Absorbent articles

Technical field

The present invention relates to a disposable absorbent article used for menstruation or incontinence.

Akita

Background art

In conventional absorbent articles such as sanitary napkins, since an absorbent body made of wood pulp or the like is in contact with the body with a permeable sheet interposed therebetween, the body part to be contacted due to movement of the contacted body or the like It cannot be said that the system was able to flexibly respond to the deformation of. Therefore, they cannot be said to fit the body well. Therefore, a gap may be formed between the body and the absorbent article, and body fluids and the like discharged from the body may leak from the gap between the absorber and the body. In addition, the absorber may be deformed when absorbing body fluids and the like, and even if the body is sufficiently fitted at the initial stage of wearing, a gap may be formed later with the body as described above. . Furthermore, when pressure is applied to the absorber by body movement or the like, the already absorbed body fluid may leak out. As a means for solving such a problem, an absorbent product or the like having a flexible structure using beads has been disclosed (Japanese Patent Application Laid-Open No. Hei 412 6357).

However, disclosed are flat napkins in which the beads are arranged over the entire flat surface, and cylindrical tampons in which the beads are arranged in the center and wrapped in an absorber. Such a napkin structure has a poor fit to the body and makes it easy to feel discomfort in the buttocks. Inability to fully adapt to the delicate shapes of the urine and pubic area, and it is likely to hinder the reliable reception and absorption of urine and blood. Because of this, it is possible for underwear to become dirty due to leakage.

Therefore, an adaptable structure that can be fitted to the delicate shape of the absorbent article wearer's urinary outlet and genital area, so that it has an excellent appearance when worn and can prevent leakage without impairing the feeling of wearing It is an object of the present invention to find the structure of the present invention and to make this adaptable structure applicable to other sanitary products and the like. Disclosure of the invention

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and its purpose is to ensure that a wearer of an absorbent article fits even a delicate shape, such as a urinary outlet or a genital area, so that a wearer can wear the absorbent article. An object of the present invention is to provide a structure of a conformable structure which has an excellent appearance at the time and which can prevent leakage without impairing a feeling of wearing. The previously disclosed adaptive structure using beads does not take into account the three-dimensional shape of the body that the absorbent article contacts, and if there is flexibility, the gap between the body and the body decreases. Was expected to be lost or lost. However, gaps may be formed during changes between different postures, such as the three-dimensional shape and sitting position of the body. Therefore, in the present invention, by taking the three-dimensional shape of the absorbent article and its change into consideration, by arranging the compliant structure at an appropriate portion, and / or The above problems can be solved by modifying the structure.

That is, a disposable absorbent article further comprising an absorbent article including an absorbent body and a sheet member covering the absorbent body so as to be arranged on the body side of the absorbent body, Include flexible parcels and structural elements that are mutually movable that are wrapped in the parcel and are absorbed by the absorber It is characterized in that objects can be transmitted therethrough and fixed narrow.

More specifically, the present invention provides the following.

(1) An absorbent article, comprising: an absorbent body; and a sheet member having at least a part of the absorbent body for permeability to an object to be absorbed and covering the absorbent body; The article may further comprise a conforming structure having a contact surface which is in contact with a wearer's or animal's genital area and / or the vicinity thereof and which flexibly deforms in accordance with the external shape of the genital area and Z or the vicinity thereof. The conforming structure comprises: a flexible packet, and a granular element that is wrapped in the packet with a predetermined space provided. An absorptive article having a thickness that allows transmission and being narrowly arranged on the body side.

Here, the absorber must absorb at least one of urine, blood, other bodily fluids, water, a mixture with other liquid or solid substances, and a mixture of any combination thereof. May be included. The sheet member may include a top sheet and Z or a back sheet. The top sheet may be a liquid-permeable sheet, for example, a hydrophilic non-woven fabric made of synthetic fibers such as polyethylene (PE) Z polyethylene terephthalate (PET), PEZ polypropylene (PP), and PPZPP. it can.

The pack sheet may have liquid impermeability, and a plastic film or a laminate sheet can be suitably used. For example, P P, P E

It can be selected from spunlaced non-woven fabric composed of T composite fiber, composite sheet of film and non-woven fabric, and the like. It is also desirable to have a predetermined durability. Although it is not always necessary, it is preferable that the surface has good appearance and touch, and it is more preferable that a color or pattern can be provided.

Wearers are generally human, but not limited to young and old. The animals are Preferably an animal other than bets, the organ mammal is more preferred _c pudendal other than human include, but are generally may refer to male and female external genital human, in the case of the animal, its equivalent It may mean. Therefore, "near the vicinity" may mean such a vicinity of the external genitalia, such as the urethral orifice and other parts of the body which are mainly outside, and may be hit by the absorbent article. May be included (equivalent parts in animals).

The contact surface in contact with the pubic region and / or the vicinity thereof may include the contact surface of the compliant structure with which the above-mentioned pubic region and the Z or the vicinity thereof come into contact with each other so as to apply pressure, directly or indirectly. "Direct" means that there is no inclusion between the contact surface and the above-mentioned hidden part, etc., and "Indirect" means that there is an inclusion between the contact surface and the above-mentioned hidden part. Good. The inclusions may be liquid or solid, and may include, for example, the above-mentioned sheet member, and these inclusions may have shape flexibility and do not significantly impair the deformation function of the contact surface. preferable. Therefore, the contact surface that is flexibly deformed in accordance with the external shape of the genital area and the vicinity thereof or Z may be deformed along the external shape of the external body such as the external genitalia. Here, “correspondingly flexible” means that the contact surface is flexible, and the shape of the contact surface without deforming or affecting the external shape of the shadow and Z or its vicinity. May change.

The conforming structure may include a contact surface that flexibly corresponds to the pubic region in contact with the above or the external shape in the vicinity thereof, and a content that is deformed via the contact surface. Such absorbent articles can generally be divided into two parts, the body side and the non-body side. The body side is the side closer to the external shape of the body in contact, and the non-body side is the other side. Therefore, the adaptation structure arranged on the side of the body is arranged relatively in contact with the outer shape of the body. The absorbent article, at least the Since it includes an adaptation structure and the absorber, the adaptation structure is usually arranged on the body side, and the absorber is arranged on the non-body side.

At least a part of the sheet member may have permeability to an object to be absorbed by the absorber, and for example, the whole or a part of the top sheet may have permeability. The material to be absorbed may be any substance that can be absorbed by the absorber, and may be permeable if at least a portion of such substance is permeable.

The sheet member covers the absorber, but does not necessarily have to be in direct contact with the absorber, and its arrangement is flexible. For example, if at least a part of the sheet member is disposed on the contact surface, the sheet member may wrap both the conformable structure and the absorber, and at least the sheet member A part may also serve as at least a part of the packet of the adaptation structure, or may overlap with the packet and wrap the adaptation structure and the absorber. As an example, the sheet member that covers the absorber may also serve as a parcel of the adaptation structure, and integrally wrap the contents of the absorber and the adaptation structure. That is, the sheet member is not limited to a single flat sheet shape, but may take a composite sheet shape (may include a three-dimensional shape) in which several sheets are combined. The flexible packet covers at least a portion of the contact surface of the conformational structure, and may be deformed or brought into contact with the contents of the conformational structure (e.g., a pubic area) by a pressing force or other factors. At least a portion of the parcel can be flexibly deformed. As described above, the contact surface on which at least a part of the parcel is disposed may directly or indirectly contact the shadow and the outer shape of Z or its vicinity. Here, “directly” may mean that the contact surface directly contacts the hidden part and the outer shape in the vicinity of Z or “indirect”, and “indirect” means that the contact surface, the hidden part and the外形 External shape at or near Z It may mean that something intervenes between and. The “something” may include any state or form such as a solid or a liquid, but preferably does not significantly impair the deformation function of the contact surface. For example, the sheet member may be interposed between an outer shape of the shade or the like and at least a part of the parcel disposed on a contact surface. The state in which a predetermined spare space is set in this parcel is not the state in which the contents wrapped in this parcel are overflowing into the parcel, but is added if necessary. It may mean a state in which the contents (whether the same or different) can be further wrapped.

The predetermined surplus space can be calculated from the surplus space ratio, which is the relative value of the force. The surplus space ratio can be expressed, for example, as follows. That is, the volume A of the content actually contained is subtracted from the volume A of the content when the content is completely filled in the package, and the difference is divided by the previous volume A and expressed as a percentage. [((A—B) /) XI 0 0]. For example, when packing a sphere q with a small diameter in a sphere-shaped parcel P, even if the volume of P is 100 cm ³ , the total volume when the sphere q is packed as closely as possible is, for example, 5 impossible also 0 be cm is ^3, if actually stuffed total volume of 3 0 cm ³ spheres q, the spare area ratio, ((5 0- 3 0) / 5 0) X 1 0 0 = 40%. Alternatively, a packing ratio expressed as a percentage by dividing the actual content volume B by the content volume A when completely filled may be used [(B / A) XI 00]. Such a marginal space ratio is preferably about 20 ° / ₀ to about 80%, and more preferably about 35% to about 65%. In calculating the extra space ratio, 1) pack the package so that the expansion and contraction of the package is small or the expansion and contraction when the contents are packed is constant; 2) the package is sufficiently flexible and It is assumed that the shape will naturally change to the optimal shape when packed. In other words, by holding the package This is based on the premise that the method of packing the contents is fixed, such as packing the contents while holding the parcel in the air. The granular element is a content wrapped in the parcel, and its number can be counted under a predetermined condition. This granular element may include cases where it is divided or divided, and does not prevent itself from being combined with other granular elements to form a larger granular element. The adaptation structure may be narrowly arranged on the body side. The term “narrow” may include representing an elongated state like a strip.

(2) The absorbent article according to (1), wherein at least one cross section of the parcel has an Ω shape, and the granular element is substantially spherical.

Here, the cross-section of the parcel may include a cross-sectional shape seen when the parcel having a three-dimensional shape is cut along an arbitrary plane, including a granular element that is one of the contents, but is more preferable. May include a cross-sectional shape of a cross-section substantially perpendicular to the front-back direction of the wearer or the like. The Ω-shaped cross-section may mean that the cross-section of the parcel has a substantially circular shape having at least one constricted shape like a drawstring bag. The constriction may include a gap (space) leading to an external space located outside the space wrapped by the parcel, and may include that the gap is sufficiently narrow. The granular element, which is one of the contents, can be taken in and out of the space leading to the outside.When the conforming structure is used, the space leading to the outside is narrowed down by some method, and the granularity of the contents is reduced. It may also mean that the element is in a state where it is difficult or impossible to get out. Further, that the granular element has a substantially spherical shape may include that the granular element has a spherical shape, a bale-shaped spherical shape, a flat spherical shape, or the like. (Or defects) may be included. For example, a hemispherical shape is included. In addition, the method includes a plurality of granular elements having the same shape. It may also include the case where one granular element is decomposed or divided into a plurality.

(3) The absorbent article according to (1) or (2), wherein the parcel is made of a liquid-permeable sheet material.

Here, the liquid-permeable sheet material includes a sheet-like material through which a liquid or other fluid can pass. As such a material, for example, a hydrophilic nonwoven fabric made of synthetic fibers such as PE / PET, PE / PP, and PPZPP can be selected. Part of the parcel, which may also be referred to as packing cover material, may be identical to a part of the topsheet.

(4) The absorbent article according to any one of (1) to (3), wherein the absorber includes a central absorber and Z or a side absorber.

Here, the central absorber is an absorber extending in a slightly narrower state in the front-rear direction of the wearer who wears the absorbent article, and may include an absorber positioned substantially at the center in the left-right direction. The absorbent may include a water-absorbing / water-retaining layer or a liquid-retaining layer, and may be composed of hydrophilic fibers such as SAP and pulp sandwiched between tissues, synthetic fibers, or a mixture thereof. Limited is that no, as an example, about 3 1 0 gZm ² SAP basis weight is the basis weight of the pulp is about 40 0 gZm ^2, or a 20% - about 30% of synthetic fibers of the pulp basis weight mixed and heat treated It may be in the form of a sheet. Further, the side absorbent body may include an absorbent body extending in a slightly narrower state in the front-rear direction of the wearer on the left and right sides as viewed from the wearer of the central absorber (the center line in the case where there is no center absorber). The absorbent may include a water-absorbing / water-absorbing layer or a liquid-retaining layer, and may be composed of hydrophilic fibers such as SAP and pulp sandwiched between tissues, synthetic fibers, or a mixture thereof. Without limitation, as an example, SAP fabric weight is about 310 gZm ² , pulp fabric weight is about 400 g / m ² , or synthetic fiber of about 20 to 30% of pulp fabric weight is mixed. The sheet may be subjected to heat treatment. (5) The absorbent article has a U-shape in its cross section, and at least a part of the elements constituting the U-shape is composed of the central absorbent and / or the side absorbent. (4) 3. The absorbent article according to claim 1.

The elements that make up the U-shape may include three elements: an upper horizontal bar, a right vertical bar connected at the end of the upper horizontal bar, and a lower horizontal bar connected to the end of the right horizontal bar. At least one of these elements may be constituted by a cross section of the central absorber and the Z or side absorber.

(6) At least a part of the parcel of the adaptation structure is a third one except for the contact surface (first surface) and the surface (second surface) directly or indirectly in contact with the absorber. The package according to any one of (1) to (5), wherein the package is arranged on a surface, and at least a part of the package arranged on the third surface is impermeable. Absorbent articles.

Here, the “surface directly or indirectly in contact with the absorber (second surface)” means that a substance (subject to be absorbed) that is absorptive to the absorber passes through the second surface. It may mean a surface that is arranged so as to be able to reach the absorber. For example, in a surface in direct contact, the object to be absorbed can immediately contact the absorber when passing through the surface. On the surface that is in indirect contact, the object to be absorbed can pass through the surface and other intervening members and contact the absorber. Therefore, even when the object to be absorbed passes through the third surface, the object to be absorbed does not reach the absorber in the system of the absorbent article according to the present invention. Here, the parcel may be a single sheet-like member, or may be a composite member having a relationship such that a plurality of sheet-like members partially overlap. The function relating to the above-described permeability may be exerted as the entire composite material.

Next, examples of the absorbent article and the like according to the present invention will be described with reference to the drawings. However, in these examples, only one specific example is given of dimensions, materials, structures and configurations. However, the present invention is not limited to these examples. [Composite sanitary product of the first embodiment]

First, the basic configuration of the composite sanitary product of the first embodiment will be described. FIG. 1A shows a substantially central cross section of the absorbent article according to the first embodiment.

The cross-sectional shape of the absorbent article 10 according to the first embodiment is a low-height silk hat cross-sectional shape. At the top, the top sheet 12 which is one of the embodiments corresponding to the sheet member, and then the granular element (or packing) covered (or included) with the parcel (or packing material) 18 Material) Adaptable structure 24 including 16, below it is the first absorber 20, and below it is the wide second absorber 22, arranged in a rectangular cross section It has been. The second absorber 22 extends to the brim portion of the silk hat cross-sectional shape, and an aggregate in which the above-described conforming structure 24 and the first absorber 20 are stacked is shown in the figure. The second absorber 22 is arranged substantially at the center on the second absorber 22. Under the second absorber 22, a back sheet 14 is arranged so that the entire second absorber 22 is placed thereon. The uppermost parcel body surface is in contact with the body via the top sheet 12, and this side is the aforementioned body side, and this uppermost parcel body surface constitutes the contact surface 19 of the compliant structure 24. I do. If the absorbent article is divided into the body side and the non-body side, it can be seen that the conforming structure 24 is arranged on the body side of the absorbent article 10 as described above. Although the top sheet 12 covers the whole from above as described above, it is flexible and easily deformed, and particularly, the portion in contact with the above-mentioned contact surface corresponds to the external shape of the shade, etc. of the wearer or the like in contact. Deformed. Therefore, the top sheet 12 has a step shape in which a convex portion is provided at the center along the upper contour line of the above-described silk hat cross-sectional shape. The top sheet 12 and the back sheet 14 are joined at a joint 15 to prevent body fluids and the like leaking from the second absorbent body 22 from leaking out of the absorbent article 10. Can be passed. This bonding can be performed by hot melt or other bonding. '

FIG. 1B shows a plan view of the absorbent article 10 (however, since the top sheet 12 covers the whole, the top sheet 12 is shown in a see-through state). The adaptation structure 24 covered by the top sheet 1 2 (shown in the transparent state of the top sheet since it covers the entire adaptation structure 24 etc. in FIG. 1B) has an absorbent structure in FIG. 1B. It is located substantially at the center of the article 10, and is arranged so that the width of the article 10 in the direction corresponding to the left-right direction as viewed from the wearer is narrower than the length extending in the front-rear direction as viewed from the wearer. In front of the conforming structure 24 (upper side in the figure), there is a front part 26 of the second absorbent body 22, and behind (lower side in the figure), there is a rear part 27 of the second absorbent body 22, Side portions 28 of the second absorber 22 are disposed on the left and right. Such a division can be made by a slit or the like (not shown in FIG. 1A) in the second absorber 22.

The top sheet 12 is made of a through-air nonwoven fabric made of hydrophilic fibers of ΡΕΖΡΕΤ, ΡΕΖΡΡ, and Ρ / Ρ, and has a basis weight of 26 g / m ² . The back sheet 14 is made of a PE film and has a basis weight of 22 g / m ² . The conforming structure 24 is moisture permeable and hydrophobic and has a width of about 35 mm, a length of about 170 mm, and a thickness of about 15 mm. The adaptation structure 24 can be arranged on the entire surface of the absorber, but more preferably can be effectively used in the vicinity of the urinary outlet or in a portion where pressure is applied to prevent liquid penetration. Further, in consideration of a sense of discomfort or the like, the width of the conforming structure 24 corresponding to the width direction of the absorbent article 10 is preferably about 30 to about 5 Omm, and the length is preferably about 100 to about 200 mm. The thickness is preferably about 5 to about 30 mm, more preferably about 10 to about 2 Omm. If it is too large, the sense of incongruity is significantly increased, and if it is too small, the function of the adaptation structure 24 is extremely low. Because it will go down. Here, the function of the conformational structure 24 is not only that it flexibly deforms in accordance with the contacted outer shape, but also that it diffuses body fluids and the like that intrude from the contact surface to the absorber below it. Includes the function of transmitting. Also, this diffusion limits the speed at which body fluids and the like penetrate into the absorber below.

The way in which the granular element 16 of the adaptation structure 24 is packed into the packet 18 will be described with specific reference to the case of the present embodiment. A through-air nonwoven fabric of the parcel body 18 is prepared in a predetermined size, and a bag-like shape is formed except for at least a part thereof. The granular element 16 is packed into the bag shape from the remaining part. As the granular element 16, for example, PP pellets, foamed beads and the like are suitably used. In this example, PP pellets of 300 g Zm ² and expanded beads of ²⁰⁰ g / m ² made of polystyrene were used. The average diameter of these elements was about 4 mm. Finally, the remaining part is closed and joined to complete the conformable structure 24. As in the case of the present embodiment, the bag shape of the parcel body 18 can be made so as to wrap one bag from one sheet, and a hemisphere and a semi-elliptical sphere are respectively formed by two sheets. Even if it is made and joined, it can also be formed by joining multiple sheets, such as three sheets or four sheets.

The granular element 16 used in the present example is a particulate matter having a small compression deformation of about 5 mm, and is independent of each other. Can be moved. The type and shape of the beads to be used are preferably selected in consideration of various necessary conditions. For example, polyolefin-based or styrene-based pellets, hollow beads, foamed beads, and the like can be suitably used. The basis weight varies greatly depending on the specific gravity of the raw materials, so it is thought that it cannot be easily limited.However, a preferable range can be selected using the above-mentioned extra space ratio or packing ratio. You. The size of the beads is preferably about 1 to about 10 mm, more preferably about 5 mm. Necessary flexibility · It should be determined according to adaptability and diffusivity.However, the size of the beads does not necessarily need to be uniform, and it is also possible to create a density gradient by changing the material. is there. It is possible to add deodorant function and antibacterial function to the beads by performing surface treatment of the beads and by properly selecting the raw material of the beads.

When the absorbent article 10 of the present embodiment is mounted, the granular element 16 constituting the conforming structure 24 moves fluidly along the shape of the crotch portion due to the wearer's body pressure and the like. The absorbent article 10 comes to fit closely to the body. When excrement comes out, it passes through the topsheet 12 and then diffuses through the gap between the granular elements 16 in the conformational structure 24, so that the conformational structure 24 and the first absorber 2 It passes through a zero boundary surface (one of the embodiments corresponding to the second surface) and reaches the absorber 20. Even if a body pressure such as a sitting position is applied, the adaptation structure 24 maintains a constant volume and hardly changes in density, so it is considered that the adaptation structure 24 does not hinder the permeation and diffusion of the liquid. Further, since the pressure applied to the absorbers 20 and 22 can be dispersed, there is an advantage that the absorption capacity of the absorbers 20 and 22 can be hardly affected by the pressurization. With the above configuration, when the absorbent article 10 of the present embodiment is worn, it can fit along the crotch shape and be in close contact with the body _c. Pressure was applied from various directions Even in this case, the conforming structure 24 has an advantage that it has excellent instantaneous absorption because it maintains a constant volume. Furthermore, there is an advantage that the absorption performance is hardly affected by the posture because there is almost no change in density.

Here, specific dimensions and the like of the adaptation structure 24 will be described with reference to the physical characteristics of a woman included in the wearer. The conforming structure 2 4 is worn When worn by a person, it extends from near the beginning of the incision to the vicinity of the anus, responds (or adapts) to the fine irregularities in the crotch of a woman, fills the gap, and always adheres to the urination or vaginal opening. A liquid such as a bodily fluid can be permeated and guided to the central absorber. To fulfill such a function, the conforming structure 24 of the present embodiment may have the following dimensions in addition to the dimensions described above. That is, the length is about 17 Omm, the width is about 4 Omm, and the thickness is about 15 mm. This is about 100 to about 14 Omm from the anterior labia to the anus, about 5 Omm from the urethral orifice to the posterior cleft, and about 250 from the anterior labia to the coccyx as female average physical characteristics. Because it is mm. Here, the length of the adaptation structure 24 is set to about 170 mm, but, for example, if the length is shorter than about 50 mm, the length is not enough to sufficiently fill the gap, and conversely, the length is longer than about 25 Omm. It is thought that the wearer will feel uncomfortable. The average female crotch width is about 3 Omm at the shortest part and about 90 mm at the maximum part. Therefore, the width of the adaptation structure 24 is set to about 4 Omm.If the width is shorter than about 10 mm, the gap cannot be sufficiently filled, and if the width is longer than 10 Omm, a sense of incongruity occurs. Become. In addition, since the average female has a genital depth of about 5 to about 20 mm, the thickness of the adaptation structure 24 is set to about 15 mm.If the thickness is smaller than about 5 mm, the gap is not enough. If it cannot be filled and it exceeds about 3 Omm, it is considered that the sense of incongruity will increase significantly.

Here, as an example, take the case of a conforming structure 24 having a width of about 50 mm and a length of about 170 mm.For example, a case where a bead having a diameter of 6 mm or 3 mm is packed as a content. State. Table 1 below summarizes the results such as the amount of beads filled and the resulting vacant space ratio. <Table 1>

Example of beads packed into an adaptive structure

Bead density 0.0283gZcm ² Packing ratio = 100-room space ratio In Table 1, circles, triangles, and bats are used to evaluate the preference of the spare space ratio. This evaluation can be considered as an absolute scale within the scope of the present embodiment, but when evaluated under various conditions, the absolute values do not always match. Therefore, it is appropriate to consider the “upper limit” and “lower limit” in the table as approximate guidelines. Rather, we can emphasize relative relationships as follows. Embodiments 1-3 are more preferable than Embodiments 13 because Embodiments 13 and 13 have a considerably small spare space ratio (a considerably large packing ratio). In addition, Embodiments 1-4 are more preferable than Embodiments 14 to 14, since Embodiments 1-4 have a considerably large spare space ratio (a considerably small packing ratio). Similarly, Embodiments 1 to 7 are preferable to Embodiments 1 to 8 because Embodiments 1 to 8 have a relatively small spare space ratio (a relatively large packing ratio). Also, since Examples 13 to 13 have a smaller spare space ratio (larger packing ratio), it is considered that Examples 1 to 8 are more preferable than Examples 13 to 13. Even with such a rough guide, the diameter of the beads is in the _c Figure 2 A及Pi diagram 2 B think it possible to compare the desirability of also a spare area rates in different such shall, female crotch The shape is schematically shown. FIG. 2A shows a cross-sectional shape of a female body at a substantially central portion in the left-right direction. In this figure, 202 indicates the navel. The pubis, which is the part A on the front, has a gentle bowl-like shape, and almost no pressure is expected from the side. At the vaginal opening of the part B, it is slightly curved toward the body (upper side in the figure), and the pressure from the side is applied most here. Therefore, in this portion, if the adaptation structure 24 becomes convex upward at the center, it can be in contact with the vaginal opening. Site C is the part of the buttocks, where there is little pressure from the side and a crack in the buttocks begins. FIG. 2B shows a bottom view of the crotch looking up from below. It can be seen that site A, site B, and site C described above are arranged in order at approximately the center. The ellipses on both sides are 2 10 for both feet. FIGS. 3A, 3B, 3C, 3D and 3E show examples of packing the granular element 16 of the conformational structure 24 into the packet 18 in various forms. For example, the package 18 may have liquid permeability on the upper and lower surfaces of the conformable structure 24.

This side surface 18b is one of the embodiments corresponding to the third surface described above. Here, the upper surface 18a and the lower surface 18c in which the film is opened and the non-opened side surface 18b may be combined. In FIG. 3A, through holes are formed in the upper surface 18a and the lower surface 18c of the package. Therefore, even if the upper surface 18a and the lower surface 18c of the parcel are liquid-impermeable, liquid can permeate.

Fig. 3B shows the first parcel 18d with a slightly hatched cross-sectional shape of the top hat and a lid so that the opening of the parcel 18d is lined up with the brim equivalent part. The second parcel 18 e and the granular element 16 are wrapped by. Hydrophobic sheets 17 (corresponding to the third package) are arranged on the sides of these main parts.

The hydrophobic sheet 17 is a side surface of this package (one of the examples corresponding to the third surface). ) Will have an impermeable function. Since the cross-sectional shape of the first packet 18d becomes narrower as it goes down, it can be called an omega (upper case) shape in a broad sense. The parcels 18d, 18e may be liquid permeable.

FIG.3C shows a fourth parcel 18 f having a shape of a high mountain at the center in the width direction and a fifth parcel 18 g extending flat at a position corresponding to the bottom thereof. It is possible to define a space having a triangular cross section with the bottom side down. This space contains granular elements 16 and a hydrophobic sheet 17 (corresponding to the sixth parcel) is arranged outside the fourth parcel 18 f forming the mountain-sided slopes on both sides. Have been. By combining these 4th, 5th and 6th parcels, You can think of it as a body. Due to the hydrophobic sheet 17 (corresponding to the sixth parcel), the parcel of this embodiment has a function of being impermeable on the side surface (one of the embodiments corresponding to the third surface). ing. In addition to the cross-sectional shapes of these embodiments, the cross-section of the conforming structure 24 can be shaped like an ellipse, trapezoid, or triangle. In addition, the fourth packet 18 f and the fifth packet 18 g may be liquid-permeable.

Here, the hydrophobic sheet 13 extends to the side surface of the absorber 20, and liquid leakage on the side surface can be more effectively prevented. In this way, the top sheet 12 may also serve as at least a part of the parcel.

By the way, regarding the surface corresponding to the second surface, FIG. 3E shows a typical adaptive structure 24 (package body) in which the so-called package 18 i has a Ω-shaped cross section and is packed with granular elements 16. 18 i and a particulate element 16). The cross-sectional shape of this parcel 18 i is, in a narrow sense, an Omega (uppercase) shape.

[Composite sanitary product of fifth embodiment]

FIGS. 12 and 13 show another pump-type mummy 80 according to the fifth embodiment of the present invention. In the developed view of Fig. 13, the pants-type ommut is composed of a bonding portion 58 of both sides of the front seat 66 on the lower side in the figure and a bonding portion 6 of both sides of the rear seat 68 located on the upper side. By joining 0 and 1 by a known method such as hot-melt, a pants-type omu 80 having a waist opening and a pair of leg openings is obtained. Fig. 12 shows a cross section (X-X, cross section in Fig. 13) of a pants-type ommut in which an absorbent article (the main part shown in cross section in Fig. 12) is arranged at the approximate center. . In this figure, from the top, the topsheet 12 covers the entire upper surface of the absorbent article, and the compliant structure 24 formed by wrapping the particulate elements 16 in the parcels 18 is placed underneath. Below that, three divided absorbers 23 are arranged side by side with the central absorber 23 placed almost directly below the adaptation structure 24. A back sheet 14 is arranged under the absorber 23, and elastic bodies 82 are arranged on both sides under a side sheet 83 extending to both sides. Below that, another elastic body 81 is arranged on both sides.

FIG. 13 is a plan view of the precursor of the pants-type omu 80 as viewed from above. In the center, a narrow and conformable structure 24 is arranged in the front-rear direction. In the figure, a front absorber 26 (first absorber) 1S is located below the rear absorber 27 (first absorber 27). Section) 1S Side absorbers 28 (second absorption sections) are arranged on both sides of the section. The curved portions on both sides have a ledge crotch gather portion 87, where the elastic body 81 is arranged. In addition, above the curved portions on both sides, a ledder side portion 74 is arranged. Absorbent gathers 85 are further arranged on the pants-type ommook 80 along both sides of the absorbent article, and form the following shape. Above the rear absorber 27, there is a rear seat 68, which has elastic portions on both sides on which elastic members 62 extending to both sides are arranged. At the upper end of the rear seat 68, there is an elastic portion provided with an elastic body 64. A front seat 66 is provided below the front absorber 26, and has elastic portions on both sides provided with elastic members 62 extending to both sides thereof.

Adhesive parts 58 and 60 in Fig. 13 are adhered to each other, and when assembling of this pants-type ommook 80 is started, it is pulled by contraction of absorber gathers 85 As a result, the second absorption section rises. This is the same operation as the redder crotch gather portion 72 of the fourth embodiment. However, in the direction in which the elastic body is arranged (extended), the leg inseam gathers 72 are not on the same line as the underbody. Therefore, since the two pulling forces work separately, the absorber gathers 85 exhibit a reduced force by the amount of force that must be applied to the redder crotch gathers compared to the redder crotch gathers 72 That would be good. Therefore, the elastic body 82 forming the absorbent gather 85 can reduce the damage given to the function of the elastic body due to use or the like, and can reduce the contact of the gather with the skin. In the present embodiment, the pants-type ommut is given as an example, but it may be an open type, and furthermore, it can be applied as a pad with a counterbore that is not integrated with the outer (body sheet). Also, it is possible to combine at least a part of the first absorption section as a pad, and to combine a pants-type pad and a pad. Furthermore, a combination of textile shorts and pats is also possible.

Elastic bodies 62 and 64 are arranged on the body sheet along the periphery. Since these elastic bodies 62 and 64 are attached to the body sheet in an extended state, they become pants-like when loosened. This condition is shown in FIG. It can be seen that the waist portion of the pan is formed by the elastic bodies 64 and 62. There is a gather made of an elastic body 94 around the underbody, and the adaptive structure 24 and the absorber 25 seen from this underbody are seen stacked.

[Composite sanitary product of seventh embodiment]

17 to 19 show a seventh embodiment according to the present invention. This shows another pants type 100. The underpants 100 are made of a known adhesive such as hot melt, which is formed by bonding the adhesive portions 58 on both sides of the lower front sheet 66 in the figure and the adhesive portions 60 on both sides of the rear seat 68. By joining by the method, a pants-type diaper 100 having a waist opening and a pair of redder openings is obtained.

Fig. 17 shows the cross section (X-X, cross section in Fig. 19) of the ommut in which the absorbent article (the main part of the cross section shown in Fig. 17) is arranged at the approximate center. In this figure, from the top, the topsheet 12 covers the entire top surface of the absorbent article, and the compliant structure 24 formed by wrapping the particulate elements 16 in the parcels 18 is arranged below it. Then, the divided absorbers 20 are arranged under substantially the same width. Below this, an integrated absorber 22, which is divided by a slit 21, extends horizontally. Under the absorber 22, a back sheet 14 is arranged, and a side sheet (or a side seed at the gathering portion of the ledger crotch) 104 extending to both sides is provided. The elastic body 82 is arranged on both sides below. Below that, another elastic body 81 is arranged on both sides so as to be sewn into the outermost layer sheet 102. Here, FIG. 19 is a plan view of the pants-type ohmu 100 developed from above and viewed from above. When viewed in plan in this plan view, the center conforming structure 24 and the absorber 2 The part containing the absorber 22 on both sides of the part containing 0 and 22 and cut by the slit 21 is called the second absorber, and the part containing the other absorber is called the first absorber. Call. In the center, a narrow and conformable structure 24 is arranged in the front-rear direction, and in the figure, the front absorber 26 (first absorption part) is located below it, and the rear absorber 27 (first Absorbing part) Force A side absorbent body 28 (second absorbing part) is arranged on both sides in a state of being cut by slits 21. The curved portions of both sides have a ledge crotch gather portion 87 on which an elastic body 81 is arranged. In addition, above the curved portions on both sides, ledder side portions 74 are arranged. Above the rear absorber 27, there is a rear seat 68, and elastic portions provided with elastic members 62 extending on both sides thereof are provided on both sides of a central portion (no elastic member) of the rear seat 68. At the upper end of the rear seat 68, there is an elastic portion provided with an elastic body 64. A front seat 66 is provided below the front absorber 26, and has elastic portions on both sides on which elastic members 62 extending on both sides are arranged.

Here, as the top sheet 12, a sheet having liquid permeability can be suitably used. For example, it can be selected from hydrophilic non-woven fabrics made of synthetic fibers such as PE / PP, PE / PET, PE / PET. As the back sheet 14, a liquid-impermeable plastic film or a laminate sheet can be used. As the outermost layer sheet 102, a hydrophobic sheet can be used. For example, it can be selected from PP spunbond or melt blown nonwoven fabric, spunlace nonwoven fabric composed of PP and PET composite fibers, composite sheet of film and nonwoven fabric, and the like. Has the required durability and can Therefore, it is preferable that the appearance and feel are good, and it is more preferable that colors and patterns can be provided. The side sheet 104 is a hydrophobic sheet and may be selected from polyolefin-based spunbond / SMS nonwoven fabric and the like. SMS nonwoven fabric is a nonwoven fabric that forms a three-layer structure by sandwiching a microweb made of PP nonwoven fabric between spun pounds made of PP nonwoven fabric.

In the absorbers 20 and 22, the absorbent core can be made of hydrophilic fiber, SAP, or a sheet obtained by combining them. The elastic members 81 and 82 can be selected from elastic yarns or sheets made of natural rubber, synthetic rubber, and thermoplastic synthetic resin. The granular element 16 of the conformational structure 24 is composed of a large number of beads made of polyolefin or urethane foam. The size of the beads is about 1 to about 10 mm in average diameter. If the size of the beads is too small, the liquid permeability is inferior. If the size is too large, the beads have a rugged feeling, and the whole feels hard. The beads are formed in a bag-like nonwoven fabric or in a permeable container. The adaptation structure 24 having a basis weight of about 1 0 0 to about 5 0 0 gZm ^2, the thickness is about 1 0 to about 2 0 mm, preferably maintained greater than about 7 mm even when a body pressure . The width is about 30 to about 5 Omm and the length is about 180 mm.

FIG. 18 shows a cross-sectional view (a portion corresponding to X—X ′ in FIG. 19) in a state where the pants-type ommut of the present example is worn. The first absorbent part shown in the figure is, from the top, an adaptation structure 24 composed of a topsheet 12, a parcel 18 and a granular element 16 as its contents, and a first absorbent body 20. , The second absorber 22, the back sheet 14, and the outermost layer sheet 102. The absorber can be composed of one or more layers. Similarly, the second absorbent section is composed of a top sheet 12, a second absorbent body 22, a pack sheet 14, and an outermost layer sheet 102 from above. Each component of the first absorption unit 0

The element and each constituent element of the second absorbing portion may be made of the same material composition, may be made of a completely different material composition, or may be in the middle. The first absorbing section in which the conforming structure 24 is disposed has a greater thickness and a higher rigidity than the second absorbing section in which the conforming structure 24 is not disposed. The redder crotch gather portion 104 is formed by attaching an elastic body 82 in an extended state between the outermost layer sheet 102 and the redder crotch gear part 104 in a stretched state. It is formed by relaxing the stretched state in the process. When the elastic body 82 is in the stretched state, it is preferable that the elastic body 82 be stretched about 1.5 to about 3 times as compared with the free state. If it is less than about 1.5 times, the second absorbent section is not sufficiently raised, and if it is more than about 3 times, it will be harder to touch the skin. The side sheet 104 may be wrapped around the elastic body 82 at a joint at the side end (the part where the side sheet 104 is bonded to the outermost sheet 102 by a method such as hot melt). However, the elastic body 82 may be located a little further inside. Due to the difference in rigidity between the ledger crotch gathers 104 and the first and second absorbent sections, the second absorbent section rises on both sides of the first absorbent section and shows a cup-shaped (or U-shaped) cross section. (Figure 18). Further, by first absorbing part to maintain a constant thickness during the load, since its height is maintained, with reference to _c Figure 1 8 to 2 1 C Orthostatic is maintained in the second absorbing part, The operation of this embodiment will be described. At the time of assembling the pants-type ommut of this embodiment, the second absorbent portion having a lower bending stiffness than the first absorbent portion is formed by the contraction (or contraction) of the redder crotch gather 104 and the application of a tensile force. Stand up on both sides. This is because the elastic body in the stretched state is arranged substantially vertically in the figure at a position separated from the center first absorption part in the left and right directions by a predetermined distance in FIG. 19, and when this stretched state is relaxed, While the substantially central vertically elongated first absorbing portion attempts to maintain its shape, the portion where the elastic body is disposed contracts. For this reason, This is because the first absorbing portion becomes relatively vertically long and has a so-called bottom shape in order to eliminate the extra length. In other words, in the bottom shape of the ship, the upright sides are arranged on both sides of the bottom. At this time, it is preferable that the absorber of the rising second absorber 28 be contracted or curved so as to match the contracted portion. It is preferable that a difference in rigidity be provided between the first absorbing section and the second absorbing section in order to promote the standing of the second absorbing section. For example, the thickness can be significantly different, slitted or cut off. Thereby, a U-shaped absorbing portion is formed in the crotch portion. The width of the central part of the inseam of the first absorption section is preferably about 5 Omm or less so that the user does not feel uncomfortable when wearing. Then, in order to prevent the standing second absorbing portion from being crushed by body pressure or the like, a layer having high pressure rigidity may be arranged at the crotch central portion of the first absorbing portion. If the thickness of about 1 O mm or more remains even when the body pressure is applied, the upright of the second absorbing section can be used effectively, and more preferably, as long as the height (width) of the second absorbing section is equal. It does not crush the second absorber. In addition, since the tensile strength of the side edge portion 74 of the redder is discontinuously higher than that of the gathering portion 104, the second absorbing portion that has been raised by the lower gathers 104 is always pulled up. (See Figure 20). As a result, the U shape is maintained.

FIG. 21A, FIG. 21B and FIG. 21C show the wearing state of these pants. FIG. 21A shows a state of the pants according to the present embodiment in a normal standing posture. The first absorption section 38 is in close contact with the genital area 36. Fig. 21B shows this state enlarged. The side 108 in the figure indicates the outside of the second absorbing section. FIG. 21C shows a state in which the foot is moved, and here, the leg is opened. As can be seen from the figure, the side 108 in the figure widens when the legs are opened, the first absorption part 38 is in close contact with the crotch, and there is always an absorption surface in the urination opening. In this way, like opening a leg or raising one leg Even if the crotch width changes due to unusual movement, the leg inseam gathers 104 and the redder side parts 74 always exist around the underbody, and the standing angle of the second absorption part changes according to the movement. A constant absorption volume is always ensured and there is no gap (Fig. 21A, Fig. 21B and Fig. 21C). With such a configuration, it is possible to prevent leakage from the crotch portion without lowering the absorbing power while improving the fit of the crotch portion. In addition, the shape of the absorption site can be maintained irrespective of the movement and posture of the foot, and a certain absorption volume can be secured. Further, the absorbing surface is always present so as to cover the crotch, and can be in close contact with the crotch.

As described above, in the absorbent article of the present invention, in order to effectively absorb body fluids and the like in contact with the body, the absorbent article further includes a structure adapted to the absorbent article including the absorber and the sheet member covering the same. Since the body is arranged on the body side of the absorber, a gap is hardly formed between the body and the absorbent article, so that the absorbent can be effectively absorbed. In addition, since this flexible structure is a loose package filled with granular elements, it can be deformed in response to subtle body irregularities. Furthermore, if this absorbent article is applied to a pants-type ommut, it is possible to provide an ommut that has almost no leakage. By adjusting the elasticity of the leg crotch gathers and the elasticity of the sides of the redder, the rigidity of the absorbent body at the center in the left-right direction from the viewpoint of the wearer of the absorbent article is adjusted. By increasing the rigidity of the absorber relative to the absorber on the side, a U-shaped (or cup) cross-section can be formed so that the bottom of the ship is formed when the ommu is worn. For this reason, it is possible to adhere to the urine outlet of the central absorbent portion of the absorbent article according to the posture including the sitting position of the wearer. In particular, in the case of a sitting position, it is preferable to fill the above-mentioned conforming structure with a granular element that does not cause the absorbent article to be crushed due to body pressure, in order to make use of this U-shaped (or cup-shaped) cross-sectional characteristic. .
