Description

The present invention relates to individually packaged absorbent articles.

Generally, absorbent articles such as sanitary napkins, panty liners, and incontinence pads are provided as individually packaged absorbent articles that are individually wrapped with packaging sheets. Packaging sheets used for individually packaged absorbent articles not only have the function of hygienically packaging the absorbent article until use, but also wrap used absorbent articles when replacing the absorbent article. It is also used for disposal.

When disposing of used absorbent articles as mentioned above, depending on the material of the packaging sheet, bodily fluids that have spread or adhered to the absorbent article may be visible through the packaging sheet, which may cause discomfort. Many users think so. Therefore, a configuration of the packaging sheet that makes it difficult to visually recognize the color of body fluids that have spread or adhered to the absorbent article, such as the red color of menstrual blood, has been studied (for example, Patent Document 1).

Japanese Patent Application Publication No. 2018-127279

Even if a packaging sheet such as that described in Patent Document 1 is used, the region of body fluid that has permeated and diffused into the absorbent article is visible to some extent from the outside. If you see information about the absorbent product (product information such as product name, logo, product specifications, etc.) along with the area of diffused body fluids, you may become aware that the product is a used absorbent product. It may become more intense, leading to increased discomfort. This discomfort depends on the user, but for example, the user may become more aware that he or she is disposing of the used absorbent article, or the absorbent article may not be as intended after being used. This can be exacerbated when you imagine that you may be seen by others without knowing it.

On the other hand, it is also conceivable that the information about the absorbent article is not attached to the absorbent article or the packaging sheet in the first place. However, before using the individually packaged absorbent article, there is also a desire to immediately recognize information about the article when viewing the individually packaged absorbent article. For example, a user who uses a plurality of individually packaged absorbent articles of different types depending on the situation may carry a plurality of individually packaged absorbent articles of different types in a pouch or the like. In such cases, being able to immediately recognize product information is important to reduce the possibility of using an absorbent article that is inappropriate for the situation.

In view of the above, one aspect of the present invention is to provide an individually packaged absorbent article in which the absorbent article is packaged with a packaging sheet, in which information about the absorbent article can be correctly recognized before opening, and the absorbent product after use can be accurately recognized. It is an object of the present invention to provide a configuration in which information about the article is difficult to be seen together with body fluids that have soaked into the absorbent article when the article is discarded.

In a first aspect of the present invention, an absorbent article is arranged on the inner surface of a packaging sheet so that the back surfaces of the absorbent articles face each other, and the absorbent article is folded toward the inner surface of the packaging sheet. The individually packaged absorbent article is an individually packaged absorbent article, wherein the absorbent article is provided with an identification mark in a first color that is a reddish color, and the packaging sheet is provided with an identification mark in a chromatic color different from the first color. A certain second color is applied, and the identification mark is visible from the outside of the packaging sheet when individually packaged.

In the first aspect, the first color identification mark attached to the absorbent article is visible through the packaging sheet. Therefore, the color of the identification mark seen from the outside of the individually packaged absorbent article, that is, the color produced by superimposing the original first color of the identification mark and the second color of the packaging sheet, is the same as that of the packaging sheet that serves as the background. The identification mark is visible against the second color, and the user can recognize the identification mark from the outside of the individually packaged absorbent article. This makes it easy to identify the type of individually packaged absorbent article before use (before opening), so even if multiple different types of individually packaged absorbent articles are in a pouch or the like, the user can Desired individually packaged absorbent articles can be easily selected.

Further, according to this aspect, the first color of the identification mark attached to the absorbent article is red. Therefore, when red body fluid such as menstrual blood is absorbed into the absorbent article and diffuses, the body fluid diffused inside the absorbent article will see through from the back of the absorbent article and overlap with the identification mark, making the identification mark visible. This makes it difficult for the information contained in the identification mark to be recognized. Therefore, visual recognition of bodily fluids in the used absorbent article and recognition of the article information based on the identification mark are unlikely to occur at the same time. With conventional configurations in which body fluids that have soaked into the absorbent article and identification marks representing information about the absorbent article are easily visible, some users may feel that they are looking at a used absorbent article. However, according to this aspect, such discomfort and disgust can be reduced.

A second aspect of the present invention is that the packaging sheet, together with the absorbent article, has a first region including one end of the packaging sheet in the first direction, and a second region including the other end opposite to the one end. , a third region between the first region and the second region, wherein the first region and the second region are folded so that the first region overlaps an outer surface of the second region. The identification mark is attached to at least one of a region facing the first region and a region facing the third region of the absorbent article.

According to the second aspect, the packaging sheet is folded inwardly together with the absorbent article into at least three folds. Such folding provides a packaging format that is simple yet protects the absorbent article from the external environment.

Further, in this aspect, the identification mark is attached to at least one of the region of the absorbent article that faces the first region and the region that faces the third region of the packaging sheet. The first region and the third region of the packaging sheet are regions of the packaging sheet that are exposed to the outside in an individually packaged state, regardless of the folding position when the packaging sheet is folded. Therefore, the identification mark attached to the area facing the first area and the area facing the third area of the packaging sheet of the absorbent article can be applied to the packaging sheet from the outside regardless of the folding position when the packaging sheet is folded. It can be seen through. Therefore, the user can easily find the identification mark on the individually packaged absorbent article before opening. Therefore, information about the absorbent article can be immediately acquired before use (before opening), and a desired absorbent article can be easily identified and taken out from among a plurality of different types of absorbent articles.

In a third aspect of the present invention, the absorbent article has a main body formed by stacking a liquid-impermeable backsheet on the back side, an absorbent body, and a liquid-permeable top sheet on the front side in this order. The back sheet has a white color.

According to the third aspect, since the backsheet is white in color, the red identification mark attached to the back surface of the absorbent article is more noticeable compared to the color of the back surface of the absorbent article. In addition, in used absorbent articles, the reddish color of menstrual blood, etc. that has soaked into the absorbent body is maintained even when viewed from the back side, so the reddish identification mark on the back side of the absorbent article is It is possible to improve the effect that the identification mark becomes difficult to recognize due to overlap with the color of the identification mark.

In a fourth aspect of the present invention, the absorbent article is arranged on the inner surface of a packaging sheet so that the back surfaces of the absorbent articles face each other, and the absorbent article is folded toward the inner surface of the packaging sheet. The individually packaged absorbent article is an individually packaged absorbent article, wherein a slip prevention part is provided on the back surface of the absorbent article, a release sheet is interposed between the packaging sheet and the slip prevention part, and the An identification mark of a first color, which is a reddish color, is attached to the release sheet, and a second color, which is a chromatic color different from the first color, is attached to the packaging sheet, and the identification mark is attached to the release sheet in an individually packaged state. It is visible from the outside of the packaging sheet.

According to the fourth aspect, the absorbent article has an anti-slip portion on the back surface thereof, and a release sheet for protecting the anti-slip portion is interposed between the packaging sheet and the absorbent article. A packed absorbent article is provided. Even with such a form of an absorbent article, the same actions and effects as those obtained in the first embodiment can be obtained. That is, in this embodiment, an identification mark of the first color is attached to the release sheet, and this identification mark is visible through the packaging sheet. Therefore, the color of the identification mark seen from the outside of the individually packaged absorbent article, that is, the color produced by superimposing the original first color of the identification mark and the second color of the packaging sheet, is changed to the color of the identification mark seen from the outside of the packaging sheet, which is the background. The identification mark is visible in two colors, and the user can recognize the identification mark from the outside of the individually packaged absorbent article. This makes it easy to identify the type of individually packaged absorbent article before use (before opening), so even if multiple different types of individually packaged absorbent articles are in a pouch or the like, the user can Desired individually packaged absorbent articles can be easily selected.

Further, according to this aspect, the first color of the identification mark attached to the release sheet is red. When a reddish body fluid such as menstrual blood is absorbed into the absorbent article and diffused, the color of the body fluid diffused into the absorbent article becomes transparent from the back side of the absorbent article. When such a used absorbent article is wrapped with a packaging sheet to which the release sheet is still attached, body fluids absorbed into the used absorbent article appear to overlap the identification mark attached to the release sheet. Therefore, the identification mark becomes difficult to see and the information contained in the identification mark becomes difficult to recognize. Therefore, visual recognition of bodily fluids in the used absorbent article and recognition of the article information based on the identification mark are unlikely to occur at the same time. With conventional configurations in which body fluids that have soaked into absorbent articles and identification marks representing information about the absorbent article are easily visible, some users may feel that they are looking at a used absorbent article. However, according to this aspect, such discomfort and disgust can be reduced.

In a fifth aspect of the present invention, the packaging sheet includes, together with the absorbent article and the release sheet, a first region including one end of the packaging sheet in the first direction, and another end opposite to the one end. a second region; and a third region between the first region and the second region, wherein the first region and the second region overlap with an outer surface of the second region. It is folded like this,
The identification mark is attached to at least one of an area of the release sheet that is opposite to the first area and an area that is opposite to the third area.

According to the fifth aspect, the packaging sheet is folded inwardly together with the absorbent article and the release sheet into at least three folds. Such folding provides a packaging format that is simple yet protects the absorbent article from the external environment.

Further, in this aspect, the identification mark is attached to at least one of the region of the release sheet that faces the first region and the region that faces the third region of the packaging sheet. The first region and the third region of the packaging sheet are regions of the packaging sheet that are exposed to the outside in an individually packaged state, regardless of the folding position when the packaging sheet is folded. Therefore, the identification mark attached to the region of the release sheet that is opposite to the first region of the packaging sheet and the region that is opposite to the third region of the packaging sheet can be passed through the packaging sheet from the outside regardless of the folding position when the packaging sheet is folded. Visible. Therefore, the user can easily find the identification mark on the individually packaged absorbent article before opening. Therefore, information about the absorbent article can be immediately acquired before use (before opening), and a desired absorbent article can be easily identified and taken out from among a plurality of different types of absorbent articles.

In a sixth aspect of the present invention, at least the back surface of the release sheet is white in color.

According to the sixth aspect, at least the back surface of the release sheet is white in color, so the red identification mark attached to the back surface of the release sheet is more noticeable compared to the color of the release sheet. Furthermore, when a used absorbent article is wrapped in a packaging sheet with a release sheet, the color of absorbed body fluids such as menstrual blood in the used absorbent article is easily visible through the packaging sheet and the release sheet. Therefore, it is possible to improve the effect that the red identification mark attached to the release sheet overlaps with the color of the body fluid, making it difficult to recognize the identification mark.

In a seventh aspect of the present invention, the color difference between the second color and the visually recognized color of the identification mark in the individually packaged state is 4 or more.

According to the seventh aspect, the color of the identification mark seen from the outside of the individually packaged absorbent article, that is, the color produced by superimposing the original first color of the identification mark and the second color of the packaging sheet. , it becomes easier to see against the second color of the packaging sheet, which is the background. Therefore, the user can improve the effect of being able to recognize the identification mark from the outside of the individually packaged absorbent article.

In an eighth aspect of the invention, the second color is a greenish color.

According to the eighth aspect, the second color applied to the packaging sheet is green, so that when a used absorbent article is wrapped in the packaging sheet and the used absorbent article is seen through the packaging sheet, The red color of menstrual blood, etc. that has soaked into the used absorbent article appears blackish. Therefore, the red color of menstrual blood becomes difficult to visually recognize. Furthermore, if an identification mark is attached to an absorbent article, the identification mark overlaps with the absorbed menstrual blood on the used absorbent article, making it difficult to see, and the packaging sheet When the used absorbent article is seen through the packaging sheet after wrapping the article, the entire area where the menstrual blood and the identification mark overlap appears black, making the identification mark even more difficult to see. In addition, if an identification mark is attached to the release sheet, if a used absorbent article is wrapped in a packaging sheet with a release sheet attached, the identification mark attached to the release sheet may be absorbed into the used absorbent article. It overlaps with menstrual blood and becomes difficult to see, and when a used absorbent article is viewed through a release sheet packaging sheet, the entire overlapped part of menstrual blood and the identification mark appears black, making the identification mark even more difficult to see.

According to one aspect of the present invention, in an individually packaged absorbent article in which the absorbent article is packaged with a packaging sheet, information on the absorbent article can be correctly recognized before opening, and the absorbent article can be discarded after use. In this case, it is possible to provide a configuration in which information about the article is difficult to see along with body fluids that have soaked into the absorbent article.

In each drawing, unless otherwise specified, the same or corresponding configurations may be denoted by the same reference numerals and the description thereof may be omitted. Further, the drawings are only schematic, and therefore, for example, the visibility state (easily visible, difficult to see, etc.) of the identification mark may differ from the actual visibility state.

[First embodiment]
FIG. 1 shows a plan view of an individually packaged absorbent article 100 according to the first embodiment. In the individually packaged absorbent article 100 (also referred to as an individually packaged absorbent article or a packaged absorbent article) according to this embodiment, the absorbent article 1 is wrapped with a packaging sheet 10 and housed inside. FIG. 2 shows a plan view of the individually packaged absorbent article 100 according to the first embodiment in an unfolded state, viewed from the side (inner surface side) on which the absorbent article 1 is placed. In FIG. 2, the absorbent article 1 is arranged such that the back side of the absorbent article 1 (the side that faces underwear when worn) faces the inner surface of the packaging sheet 10, and the absorbent article 1 is The front side (the side facing the skin when worn) is exposed. In FIG. 2, the absorbent article is shown as a partially cutaway view.

<Basic structure of absorbent article>
In this embodiment, the absorbent article 1 packaged with the packaging sheet 10 may be a flat and elongated article that is worn so as to face an outlet for body fluids (menstrual blood, vaginal discharge, urine, etc.).

Specific examples of the absorbent article 1 may be sanitary napkins, panty liners (vaginal discharge sheets), light incontinence pads, and the like. In this embodiment, a sanitary napkin is taken as an example. As shown in FIG. 2, the absorbent article 1 includes a liquid-permeable top sheet 3, a liquid-impermeable back sheet 2, and an absorbent body 4 disposed between the top sheet 3 and the back sheet. It has a main body 8.

As the back sheet 2, a sheet material having at least water-blocking properties, such as an olefin resin sheet such as polyethylene or polypropylene, can be used. A laminated nonwoven fabric made by laminating a nonwoven fabric on a polyethylene sheet or the like, or a laminated sheet of a nonwoven fabric with a waterproof film interposed therebetween to ensure substantially liquid impermeability, etc. can be used. Moreover, a material having moisture permeability may be used.

As the top sheet 3, a perforated or non-perforated nonwoven fabric, a porous plastic sheet, or the like is suitably used. The material fibers constituting the nonwoven fabric include, for example, olefins such as polyethylene and polypropylene, synthetic fibers such as polyester and polyamide, recycled fibers such as rayon and cupro, blended fibers thereof, and natural fibers such as cotton, either singly or Two or more types can be used in combination.

The absorbent body 4 is not limited to any material as long as it can absorb and retain body fluids, but preferably contains cotton-like pulp and a water-absorbing polymer. As the water-absorbing polymer, superabsorbent polymer granules (SAP), superabsorbent fibers (SAF), and combinations thereof can be used. Examples of the pulp include chemical pulp obtained from wood, cellulose fibers such as dissolving pulp, and those made of artificial cellulose fibers such as rayon and acetate.

The thickness of the absorbent body 4 may be 0.5 to 25 mm. The absorbent body 4 may have a structure in which a region corresponding to the body fluid discharge port (body fluid discharge port corresponding region) or a region facing the buttock groove behind the body fluid discharge port corresponding region is bulged. The absorbent body 4 has a size and shape that does not protrude from the top sheet 3 and the back sheet 2, and at least at the front and rear edge portions of the absorbent body 4, the outer edges of the back sheet 2 and the top sheet 3 are hot-melt. They are bonded using adhesives such as, heat sealing, ultrasonic sealing, and other adhesive means.

A slip-stopping portion may be formed on the back surface of the backsheet 2 of the main body 8 to prevent the absorbent article 1 from slipping from the underwear when worn (not shown in FIGS. 1 and 2). The anti-slip portion may be adhesive or non-adhesive. When the anti-slip portion is adhesive, the anti-slip portion can be formed by applying an adhesive, for example. As the adhesive, for example, one whose main components are a styrene polymer, a tackifier, a plasticizer, or a combination thereof is preferably used. When the anti-slip portion is adhesive, the inner surface of the packaging sheet 10 is subjected to a peeling process (mold release process), and when the absorbent article 1 is taken out from the packaging sheet 10. To prevent an adhesive slippage prevention part from remaining on a packaging sheet 10.

On both sides of the skin side (the side facing the wearer's skin, the inner side) of the main body 8, side sheets 7, 7 are provided along the longitudinal direction of the main body 8 on both sides of the top sheet 3 in the illustrated example. It may be. As the side sheets 7, 7, a water-repellent nonwoven fabric or a hydrophilic nonwoven fabric can be used.

As shown in FIG. 2, the absorbent article 1 has wings W, W extending to the sides of the main body 8, respectively. However, the absorbent article in this embodiment may have wings W and no W. When the wings W, W are provided, the wings W, W may be formed by joining the side sheet 7 and the back sheet 2, as shown in FIG. Furthermore, an adhesive slip-preventing portion should be provided on the back side of the wings W, W, that is, on the back surface of the back sheet 2 that constitutes the wings W, W, in the same way as the slip-preventing portion provided on the back side of the main body 8. I can do it. Thereby, when worn, the wings W, W can be folded back to the underwear side and fixed to the underwear.

The total length of the absorbent article 1 can be 140 to 430 mm, and the width of the absorbent article 1 (width of the main body excluding the wings if it has wings) can be 50 to 130 mm.

<Basic composition of packaging sheet>
The packaging sheet 10 may also have an elongated shape similar to the shape of the absorbent article 1 in the unfolded state. In the description of this embodiment, the longitudinal direction D1 of the packaging sheet 10 may be referred to as a first direction, and the direction perpendicular to the first direction, that is, the lateral direction D2 of the packaging sheet 10, may be referred to as a second direction. As shown in FIG. 1, the packaging sheet 10 and the absorbent article 1 are arranged so that their longitudinal directions are the same, and then folded to form individually packaged absorbent articles. Therefore, the longitudinal direction D1 and the lateral direction D2 in this embodiment correspond to the longitudinal direction D1 and the lateral direction D2 of the absorbent article 1, respectively.

In the illustrated example, the packaging sheet 10 has a rectangular shape in plan view, but it may have a shape such as an oblong oval. Moreover, the planar view shape of the packaging sheet 10 may be a non-elongated shape such as a square or a circle.

The dimensions of the packaging sheet 10 depend on the size and shape of the absorbent article 1 to be packaged, but for example, when the packaging sheet 10 is completely unfolded (unfolded, FIG. 1), the length in the longitudinal direction D1 ( The length in the lateral direction D2 (sometimes simply called the width) can be from 70 to 250 mm.

The material constituting the packaging sheet 10 is not particularly limited, and may be a material that has a predetermined color and can be seen through the identification mark inside the packaging sheet 10 when viewed from the outside of the individually packaged absorbent article 100. As long as the material is not limited (described in detail later), it may be a nonwoven fabric, a resin film, paper, or the like.

It is preferable to use a nonwoven fabric as the material for the packaging sheet 10 because it can improve texture, flexibility, and the like. The nonwoven fabric used is preferably a melt-blown nonwoven fabric, a spunbond nonwoven fabric, or the like, and a combination of layers of these nonwoven fabrics and a plurality of laminated layers may also be used. Further, the fibers constituting the nonwoven fabric may be polyolefins such as polypropylene and polyethylene, polyesters, polyamides such as nylon, and the like.

When a resin film is used as the material for the packaging sheet 10, the packaging sheet 10 becomes difficult to tear. Furthermore, it is preferable to print on a resin film because the outlines of the printed characters and patterns can be made clear and the degree of freedom in design increases. When a resin fill is used for the packaging sheet 10, examples of the resin used include polyolefins such as polypropylene and polyethylene, polyester, and polyvinyl alcohol. The resin film is preferably one that has been stretched. Further, the resin film may be a non-breathable film or a breathable film.

By using paper as the material for the packaging sheet 10, there is less environmental burden upon disposal, and the natural texture of natural materials can be imparted. In this specification, paper refers to a flat plate obtained by gluing plant fibers and other fibers together with an adhesive. In particular, it can refer to those whose main raw material is vegetable fiber (pulp), for example, those whose fiber content is 50% or more, preferably 80% or more. The types of pulp contained in the paper may include wood pulp, non-wood pulp, and waste paper pulp, and these may be either mechanical pulp or chemical pulp. Additives may be added to the paper. Further, specific examples of paper used for the packaging sheet 10 include various types of paper such as Western paper, Japanese paper, processed paper, and synthetic paper. In addition, paper that has been conventionally used for other purposes, such as newsprint, printing paper (including high-quality paper), writing paper, drawing paper, wrapping paper, tissue paper, miscellaneous paper, etc., may be used unprocessed or processed. It can also be used as Note that the paper may be bleached or unbleached. Unbleached paper has a more natural texture. Further, since the inside becomes difficult to see through, it becomes difficult to see the wrapped absorbent article 1, and even when a used absorbent article is wrapped at the time of disposal, it becomes difficult to see the used absorbent article, which is preferable.

The paper used as the material for the packaging sheet 10 can be thin paper with a low basis weight so that it is easy to fold when packaging the absorbent article 1 and to maintain the packaged state. The thin paper may be thin imitation paper, Indian paper, rice paper (used as cigarette paper, etc.), glassine paper, tissue paper, toilet paper, filter paper, or the like. Moreover, the paper may be processed after paper making. Examples of the above-mentioned processing include crepe processing, embossing, calendar processing, water repellent processing (mold release processing), slit processing, ply processing, printing processing, and the like. Crepe processing and embossing can improve both strength and flexibility. Note that when the packaging sheet 10 is subjected to water repellent treatment (mold release treatment), a water repellent containing, for example, silicone resin, paraffin resin, fluororesin, etc. It may be coated on at least one of the side (which is exposed to the outside in a state of being exposed) and the inner surface opposite to the outer surface.

When paper is used as the material for the packaging sheet 10, its basis weight may be 50 to 100 g/m ² . Further, the thickness of the paper can be preferably 40 to 200 μm, more preferably 100 to 200 μm.

One packaging sheet 10 may be composed of a single layer containing any of the above-mentioned different materials, or may be a laminate formed by laminating a plurality of layers. The materials contained in each layer of the plurality of layers may be the same or different. For example, a sheet formed by laminating a resin film and paper can be used.

<Packaging structure>
When packaging the absorbent article 1 with the packaging sheet 10, the absorbent article 1 is placed on the inner surface of the packaging sheet 10, and both of them are folded in three or more toward the inner surface, so that the absorbent article 1 is wrapped inside the packaging sheet 10. It can be packaged so that it is hidden inside.

As shown in FIG. 2, the packaging sheet 10 has a first region R1 including one end 11 in the longitudinal direction D1, and a second region R2 including the other end 12 on the opposite side of the one end. The area between the second area R2 and the second area R2 is the third area R3. When folding the packaging sheet 10 for packaging the absorbent article 1, the second region R2 is folded inward at the second folding position Fx2 along the lateral direction D2, and then the first region R1 is folded in the lateral direction Fold it inward at the first folding position Fx1 along D2. At that time, the first region R1 and the second region R2 are made to overlap, more specifically, the first region R1 is made to overlap the outer surface of the second region R2, and the paper is folded into three (inward three-fold). As a result, as shown in FIG. 1, an individually packaged absorbent article 100 is obtained which is folded and has the absorbent article 1 housed therein.

Note that, before folding the second region R2, the second region R2 is folded at one or more folding positions along the horizontal direction D2 between the other end 12 of the second region R2 and the second folding position Fx2. By doing so, it is possible to obtain a packaging structure of more than four folds.

The absorbent article 1 is placed on the inner surface of the packaging sheet 10 so that the longitudinal direction of the absorbent article 1 is aligned with the longitudinal direction D1 of the packaging sheet 10 before the packaging sheet 10 is folded. Then, the absorbent article 1 and packaging sheet 10 are folded together. After folding, both edges in the direction orthogonal to the folding direction, that is, both edges in the lateral direction D2, are sealed to form sealed portions 15, 15. The seal parts 15, 15 can be peeled off by the user's normal force, and are peeled off when the user lifts the first area R1 away from the second area R2 when opening the package. The seal portions 15, 15 may be formed by heat sealing, ultrasonic sealing, adhesive, or mechanical methods. The mechanical method is, for example, a method of deforming the surface of the packaging sheet by embossing or the like to cause the packaging sheets to engage with each other. The seal portions 15, 15 are preferably formed within a range of 3 to 10 mm from the edge in the lateral direction D2.

When the absorbent article 1 has wings W, W as in the illustrated example, the wings W, W are placed on the surface side (skin side or top sheet 3 side) of the absorbent article 1 at wing fold positions Fy, Fy. After that, the first region R1 and the second region R2 are folded in advance.

Such an individual packaging form in which the packaging sheet 10 is folded in one direction and both edges in a direction perpendicular to the folding direction are sealed is preferable because absorbent articles can be hygienically housed in a simple procedure.

Further, as shown in FIG. 1, the first region R1 overlapped on the outside may be fixed to the second region R2 with a sealing tape 18. The presence of the sealing tape 18 can prevent unintentional opening of the individually packaged absorbent article 100 before use. Furthermore, when opening the package, the user can lift and peel off the first region R1 from the second region R2 by holding and pulling the sealing tape 18. Furthermore, when disposing of the used absorbent article when replacing the absorbent article, when wrapping the used absorbent article with the packaging sheet 10, the ends of the packaging sheet 10 are fixed with the sealing tape 18. You can also.

<Identification mark>
FIG. 3 shows a state in which the absorbent article 1 shown in FIG. 1 is taken out and turned over, that is, a plan view of the absorbent article 1 seen from the back side. As shown in FIG. 2, in this embodiment, an identification mark _MA is attached to the back surface of the absorbent article 1.

The identification mark M _A may include information regarding the absorbent article 1 . More specifically, the product name, manufacturing company name, sales company name, and product specifications of the absorbent article 1, i.e., product length, presence or absence of wings, wing length, thickness (normal type, slim type, etc.), Information such as recommended use (daytime use, nighttime use, frequent use), feeling of wearing (soft type, good breathability), etc. may be included. By looking at the identification mark _MA , the user can immediately determine the type of absorbent article 1. Specifically, the identification mark _MA may include one or more of letters, symbols, codes, pictures, and logos. Note that the identification mark _MA may include information other than information regarding the absorbent article 1, or a portion that does not include information.

In this embodiment, the identification mark _MA has a first color 21 of a reddish color. As used herein, "red color" refers to a color in which the a ^* value of the CIE1976 L ^* a ^* b ^* color space is positive, preferably 45 to 98. More preferably, the L ^* value of the CIE 1976 L ^* a ^* b ^* color space of the first color 21 may be 50 to 97, and the b ^* value may be 5 to 94.

In the example shown in FIG. 2, the identification mark _MA is attached to the back surface of the backsheet 2 of the absorbent article 1. However, as long as it is visible from the back side of the absorbent article 1, the identification mark _MA may be attached to the surface of the backsheet 2, that is, the surface facing the absorbent body 4, or may be placed on both sides of the backsheet 2. may be attached.

Although the method for applying the identification mark _MA is not particularly limited, it is preferable that the identification mark _MA is formed by, for example, applying a coloring agent to the absorbent article 1 by printing. Alternatively, it may be formed by pasting colored pieces.

Although the size of the identification mark M _A is not particularly limited, it is preferable that the identification mark M _A recognized as one or a group is attached with an equivalent circle diameter in the range of 10 to 50 mm. Further, a plurality or groups of identification marks _MA may be attached at a distance from each other. For example, if the identification mark _MA includes characters, the size may be 10 to 40 points.

In addition, when the identification mark M _A is attached directly to the absorbent article 1 as in this embodiment, even after the absorbent article 1 is taken out from the packaging sheet 10, the type of the absorbent article 1 cannot be determined. You also get the advantage of knowing.

In this embodiment, the color of at least the back surface of the backsheet 2 of the absorbent article 1 is preferably a white color. "White color" is an achromatic color, for example, a color in which the a ^* value and b ^* value of the CIE1976 L ^* a ^* b ^* color space are both -10 to 10, and the L ^* value (lightness) is 90 to 100. be. Thereby, the identification mark _MA attached to the backsheet 2 can be made to stand out from the color of the entire backsheet 2. Even when the identification mark M _A is viewed through the packaging sheet 10 in the individually packaged state, it is not easily affected by the color of the back sheet 2, and the background color (second color) of the packaging sheet 10 is The third color 23 of the identification mark MA visible through the sheet 10 becomes easier to see clearly.

<Identification mark when individually packaged>
FIG. 4 shows a state in which the packaging sheet 10 is stacked on the absorbent article 1 of FIG. 3. Moreover, FIG. 5 shows a state after the packaging sheet 10 and the absorbent article 1 are folded together from the state shown in FIG. 4, as viewed from the third region R3 of the packaging sheet 10. As shown in FIGS. 4 and 5, the identification mark _MA is visible through the packaging sheet 10. In this specification, "visible" refers to the fact that a user with normal visual acuity and color vision can recognize the information contained in the identification mark _MA in a normal manner.

As mentioned above, while the identification mark M _A has the first color 21 which is a reddish color, the packaging sheet 10 is given the second color 22 which is a chromatic color different from the first color 21. . This second color 22 has a color difference ΔE between the second color 22 and the third color 23, assuming that the color of the identification mark M _A visible through the packaging sheet 10 is a third color 23 (FIGS. 4 and 5). is preferably set to be 4 or more. The color difference ΔE is the color difference ΔE in the L ^* a ^* b ^* color space of CIE1976, and ΔE=[(ΔL ^* ) ² +(Δa ^* ) ² +(Δb ^* ) ² ] ^1/2 . Due to the above-mentioned color difference ΔE between the color of the packaging sheet 10 itself (second color 22) and the color of the identification mark _MA (third color 23) that is visible through the packaging sheet 10. Since the third color 23 of the identification mark _MA stands out against the second color 22 of the packaging sheet 10, which can be called the background, the user can immediately identify the individually packaged absorbent article 100. Therefore, for example, even if a plurality of different types of individually packaged absorbent articles are contained in a pouch or the like, the user can easily select the individually packaged absorbent article that he or she wants to use.

Further, the second color 22 of the packaging sheet 10 (the color when the packaging sheet 10 is viewed from the outside) may be a greenish color. A "green color" refers to a negative a ^* value in the CIE1976 L ^* a ^* b ^* color space. Further, the a ^* value of the second color 22 is preferably from -40 to -3. Furthermore, it is preferable that the L ^* value of the CIE1976 L ^* a ^* b ^* color space is 50 to 97, and the b ^* value is 0.2 to 40. Note that the second color 22 can be adjusted to be a complementary color to the first color 21, or to be a color within a range in which the hue angle h deviates from the complementary color by 30° or less.

The second color 22 of the packaging sheet 10 can also be applied by printing or the like. The second color 22 may be applied to the packaging sheet 10 entirely or partially. Therefore, the entire area of the packaging sheet 10 may be printed solidly, or the entire area of the packaging sheet 10 may be printed with a halftone dot pattern. In the case of a halftone dot pattern, the halftone dot area ratio is preferably 30 to 100%. When the dot area ratio is 100%, solid printing is performed. Moreover, the colors in the packaging sheet 10 may be formed so that the user can see that there are colored areas and non-colored areas. For example, in the packaging sheet 10, the portions where the seal portions 15, 15 are formed may not be colored. Furthermore, a pattern may be drawn on the packaging sheet 10 depending on the presence or absence of the second color 22 and/or the shade of the color.

If the packaging sheet 10 can be visually recognized as the second color 22 when viewed from the outside, and if the color difference ΔE with the second color 22 is 4 or more when viewed from the outside with the identification mark M _A superimposed, the packaging sheet 10 is suitable for packaging. The outer surface of the sheet 10 may be colored, the inner surface may be colored, or both sides may be colored. However, as shown in the examples shown in FIGS. 1 to 5, the second color 22 that is visible from the outside and the first color 21 of the identification mark M _A are better in the case where the outer surface is colored. This is preferable because it is easy to adjust the color (third color 23) that is visually recognized when the two colors are superimposed.

The second color 22 of the packaging sheet 10 may be applied to at least an area that overlaps with the identification mark _MA , preferably an area that includes the identification mark _MA , when the packaging sheet 10 is overlapped with the absorbent article 1. Here, the location where the identification mark _MA is attached is not particularly limited, but it may be attached preferably within the range of the main body 8, more preferably within the range of the absorber 4 in plan view. Further, in the individually packaged state, it is attached to an area facing the packaging sheet 10 that is exposed to the outside, preferably at least one of the area facing the third area R3 and the area facing the first area R1 of the packaging sheet 10. It is preferable. Therefore, in correspondence with such an identification mark M _A , the second color 22 of the packaging sheet 10 is applied to the area disposed on the outside (the area exposed to the outside), that is, the second area R2 in the individually packaged state. It is preferable that the mark is attached to an area excluding the area overlapping with the first area R1.

In this embodiment, the identification mark M _A is attached to the absorbent article 1 and this identification mark M _A is visible from the outside of the individually packaged absorbent article 100. There is no need to write it down. Therefore, as long as the packaging sheet 10 has a predetermined color (second color) in relation to the color of the identification mark (first color), the degree of freedom in designing the packaging sheet 10 can be increased.

In addition, in the individually packaged absorbent article 100, from the viewpoint that the identification mark _MA attached to the absorbent article 1 can be easily seen through the packaging sheet 10, it is preferable that the packaging sheet 10 is made of a nonwoven fabric. In that case, the packaging sheet 10 may be colored by printing a chromatic color on a colorless (white) non-woven fabric, by using pre-colored fibers themselves to form the non-woven fabric, or by using colored fibers themselves. A nonwoven fabric made of fibers may be further printed.

<Identification mark at the time of disposal>
Next, the state of the identification mark at the time of disposal will be explained with reference to FIGS. 6 to 8. FIG. 6 shows the used absorbent article 1' in a rolled up state after the absorbent article 1 in FIGS. 1 to 5 has been used. This used absorbent article 1' is rolled up so that the top sheet 3, to which body fluids are directly attached, is on the inside and the back sheet 2 is on the outside. In the example shown in FIG. 6, the used absorbent article 1' is rolled up from the end in the longitudinal direction D1, but the used absorbent article 1' may be folded in multiple folds in the longitudinal direction D1. In the used absorbent article 1', as shown in FIG. 6, body fluid can be visually recognized as a body fluid diffusion portion BD soaked into the backsheet 2 side.

In the used absorbent article 1', the reddish color of body fluids, especially menstrual blood, is often visible through the back side of the absorbent article even if the article is rolled or folded with the top sheet 3 inside. If such transparent body fluid comes into contact with the user's eyes together with the identification mark M _A attached to the absorbent article 1, the user may be disposing of the used absorbent article 1' or The awareness that the user is holding the item becomes stronger, which may increase the user's discomfort or disgust. On the other hand, in this embodiment, since the identification mark M _A attached to the absorbent article 1 is reddish in color, the reddish color of menstrual blood etc. that can be seen through the back side of the used absorbent article 1' is If they overlap, the identification mark _MA becomes difficult to visually recognize, and the information about the article contained in the identification mark _MA becomes difficult to recognize. As a result, body fluids and product information are simultaneously recognized by the user in the used absorbent article 1', and the used absorbent article 1' is unintentionally exposed to the eyes of others. If the user imagines that the body fluid and the information about the item will be recognized at the same time, the discomfort and aversion that may increase can be alleviated.

Furthermore, when replacing an absorbent article, many users wrap the used absorbent article 1' in the packaging sheet 10 that has been removed from a newly opened individually packaged absorbent article and discard it. FIG. 7 shows a state where the used absorbent article 1' is about to be wrapped with the packaging sheet 10, and FIG. 8 shows a state where the used absorbent article 1' is wrapped with the packaging sheet 10.

As shown in FIG. 7, the used absorbent article 1' is placed on the inner surface of the packaging sheet 10 (the surface opposite to the surface to which the sealing tape 18 is attached), and for example, if the sealing tape 18 is It is placed near the other end 12 on the opposite side to the one end 11 in the longitudinal direction D1, and is rolled up from the other end 12 side. As shown in FIG. 8, after the packaging sheet 10 is wrapped around the used absorbent article 1', one end 11 of the packaging sheet 10 in the longitudinal direction D1 is connected to the other end of the packaging sheet 10 using the sealing tape 18. Attach to the area. As a result, body fluids attached to the used absorbent article 1' are less likely to stick to hands, and the used absorbent article 1' has a compact size, so that it can be disposed of smoothly.

As described above, in this embodiment, the second color 22 is applied to the packaging sheet 10, and this second color 22 is applied as a watermark to the packaging sheet 10 while the absorbent article 1 is wrapped in the packaging sheet 10. Preferably, the adjustment is made so that the color difference ΔE from the color (third color 23) when viewing the identification mark MA is 4 or more so that the identification mark M _A can be seen. Therefore, the reddish color of bodily fluids such as menstrual blood that appears to have soaked into the back surface of the used absorbent article 1' is not visually recognized as a reddish color when the packaging sheets 10 are stacked. Therefore, especially for users who do not like the red color of blood, it is possible to reduce discomfort when disposing of the used absorbent article 1'. Furthermore, when the second color 22 applied to the packaging sheet 10 is a green color, the body fluid diffusion portion BD looks black when viewed through the packaging sheet 10, and the discomfort is further reduced.

In addition, as described above, the identification mark M _A attached to the absorbent article 1 overlaps with the body fluid diffusion portion BD visible from the back side, making it _difficult to be visually recognized. When viewed through the packaging sheet 10 to which the second color 22 is applied such that the color difference ΔE between the second color 22 and the third color 23 is 4 or more as described above, the entire area where the two colors overlap is a reddish color. The color will deviate from that. Therefore, the identification mark MA becomes even more difficult to visually recognize. Furthermore, if the packaging sheet 10 is a green color, that is, a complementary color to a red color, the entire region where the body fluid diffusion portion BD and the identification mark M _A overlap appears blackish, so that the identification mark M _A is more easily recognized. This further reduces the user's discomfort.

Note that when the used absorbent article 1' is wrapped in the packaging sheet 10 and disposed of, the information on the article is not attached to the packaging sheet 10, especially from the viewpoint that the body fluid and the information on the article are not visible at the same time. is preferred.

Even when disposing of the used absorbent article 1', if at least the back side of the back sheet 2 of the absorbent article 1 is white in color as described above, the back sheet 2 of the used absorbent article 1' will be disposed of. Since the color of the visible body fluid is maintained in a reddish color, it overlaps with the first color 21 (reddish color) of the identification mark _MA , thereby improving the effect of making the identification mark _MA difficult to see.

[Second embodiment]
An individually packaged absorbent article 200 according to a second embodiment of the present invention will be described with reference to FIGS. 9 to 11. The individually packaged absorbent article 200 according to the second embodiment has the same basic configuration as the individually packaged absorbent article 100 according to the first embodiment, but protects the slip prevention part arranged on the back side of the absorbent article 1. The difference is that a release sheet is provided for the absorbent article 1, and that the above-mentioned identification mark is attached to the release sheet instead of the absorbent article 1.

FIG. 9 is a view of the absorbent article 1 viewed from the back side, and corresponds to FIG. 3 referred to in the description of the individually packaged absorbent article 100 according to the first embodiment. In the example shown in FIG. 9, the anti-slip portion 9 on the back side of the absorbent article 1 is clearly shown. Further, a release sheet 30 is disposed to cover the anti-slip portion 9. The release sheet 30 is a sheet that has been subjected to release treatment (mold release treatment) on the surface (surface) facing the anti-slip portion 9 .

In the example shown in FIG. 9, a plurality of anti-slip portions 9, 9, 9 extending along the longitudinal direction D1 are spaced apart from each other in the lateral direction D2, but the arrangement of the anti-slip portions is as shown in the example. Not limited to. For example, a plurality of anti-slip portions extending along the lateral direction D2 may be spaced apart from each other and arranged side by side in the longitudinal direction D1.

In this embodiment, as shown in FIG. 9, an identification mark _MB is attached to the back surface of the release sheet 30. The identification mark _MB differs only in that the location where it is attached is on the release sheet 30, and the information it contains, the size it is attached to, the method it is attached to, the location where it is attached, etc. It may be the same as the identification mark _MA described in the embodiment. The color of the identification mark _MB is also a reddish color like the identification mark _MA .

In the example shown in FIG. 9, the identification mark _MB is attached to the back side of the release sheet 30, but the identification mark _MB is visible when the release sheet 30 is superimposed on the absorbent article 1. If so, it may be attached to the surface of the release sheet 30. However, when forming the identification mark _MB by printing a coloring agent, in order to prevent the colorant from adhering to the anti-slip portion 9 and reducing the anti-slip effect, the identification mark _MB is printed with a release sheet. 30 is preferably attached to the back side.

FIG. 10 shows a packaging sheet 10 stacked on the absorbent article 1 and release sheet 30 shown in FIG. Moreover, FIG. 11 shows a state after the state shown in FIG. 10 is folded and packaged, as viewed from the third region R3 of the packaging sheet 10. The packaging sheet 10 in the second embodiment can be similar to the packaging sheet in the first embodiment. In this embodiment, as shown in FIGS. 10 and 11, in addition to the packaging sheet 10 and the absorbent article 1, the release sheet 30 disposed between the packaging sheet 10 and the absorbent article 1 is also folded. .

As shown in FIGS. 10 and 11, the identification mark _MB attached to the release sheet 30 is visible through the packaging sheet 10. Also in this embodiment, a second color 22 is applied to the packaging sheet 10, and this second color 22 is set so that the identification mark _MB can be visually recognized through the packaging sheet 10. Further, the second color 22 has a color difference ΔE between the second color 22 and the third color 23, assuming that the color of the identification mark _MB visible through the packaging sheet 10 is the third color 23 (FIGS. 10 and 11). It is preferable that the number is set to 4 or more. As a result, when the individually packaged absorbent article 200 is viewed from the outside, the third color 23 of the identification mark M _B , which is visible through the water, stands out against the second color 22 of the packaging sheet 10, which can be said to be the background. The user can immediately identify the individually packaged absorbent article 200, and the same effects as the individually packaged absorbent article 100 according to the first embodiment can be obtained in the individually packaged state.

The release sheet 30 in this embodiment may be non-separably adhered to the packaging sheet 10. Therefore, when replacing the absorbent article, when the packaging sheet 10 is removed from a newly opened absorbent article, both the packaging sheet 10 and the release sheet 30 are removed. Therefore, when wrapping the used absorbent article with the packaging sheet 10 when disposing of the used absorbent article, the used absorbent article is wrapped in the packaging sheet 10 with the release sheet 30 adhered to the inner surface. The wrapping method can be performed in the same manner as in the first embodiment (FIGS. 7 and 8).

When a used absorbent article is wrapped in the packaging sheet 10 with a release sheet 30 attached, the red-colored identification mark M _B attached to the release sheet 30 is absorbed and diffused into the used absorbent article, and the back side It overlaps with the body fluid diffusion part that can be seen from above. Therefore, the identification mark _MB is difficult to see and the information contained in the identification mark _MB is difficult to recognize. Therefore, both the body fluid and the information on the absorbent article can be prevented from coming into contact with the eye, and as in the first embodiment, discomfort and disgust can be reduced.

Furthermore, even at the time of disposal, since the packaging sheet 10 adjusted to the predetermined second color 22 is placed on the outside, bodily fluids soaked in the absorbent article 1 and the identification mark M _B attached to the release sheet 30 are removed. Seen through packaging sheet 10. Since both the body fluid and the color of the identification mark _MB (third color 23) are colors that deviate from red-based colors, discomfort for users who are not good at the red color of blood is reduced. Furthermore, when the packaging sheet 10 is greenish in color, both the body fluid and the identification mark _MB (third color 23) are blackish, and discomfort and disgust can be further reduced.

[Modified example of packaging sheet]
FIGS. 12 and 13 show a modification example in which the packaging sheet 10 has a different design. Although FIGS. 12 and 13 are shown as a modification of the first embodiment, they may be a modification of the second embodiment. As shown in FIGS. 12 and 13, the packaging sheet 10 can be visually recognized as the second color 22 when viewed from the outside, and has a color difference ΔE from the second color 22 when viewed from the outside when superimposed on the identification mark _MA . If it is 4 or more, patterns or patterns other than halftone dots may be added. Even in the case of the packaging sheet 10 having a pattern or design other than halftone dots, the area ratio of the colored region may be 30 to 100% of the entire area of the packaging sheet 10.

For example, as shown in FIG. 12, the design of the packaging sheet 10 may be a checkered pattern. That is, the pattern may be such that small portions colored with a chromatic color and small portions not colored are arranged in a grid pattern.

Furthermore, as shown in FIG. 13, even if the pattern is a so-called striped design in which lines having a predetermined width colored with a chromatic color and lines having a predetermined width without coloring are arranged alternately. good. As shown in FIG. 13, the direction of the stripes may be diagonal, or may be along the longitudinal direction D1, or may be along the lateral direction D2.

Although the present invention has been described above based on the embodiments, the present invention is not limited to these embodiments. Further, the above-described embodiments may be subjected to various changes, modifications, substitutions, additions, deletions, combinations, etc. within the scope of the claims, and these also belong to the technical scope of the present invention. Moreover, the above-mentioned features can also be combined arbitrarily. For example, in the second embodiment, a reddish identification mark _MA may be additionally attached to the absorbent article 1 so as not to overlap with the identification mark M _B attached to the release sheet 30.
