Description

  The present invention relates to a film package, and more particularly, to a film package for packaging sanitary paper folded in a pop-up manner.

  Conventionally, pillow packaging and gusset packaging in which a hygienic paper bundle such as tissue paper, toilet paper, kitchen paper, paper hand towels, paper towels and wipers are stored in a packaging bag formed of a flexible film in a pop-up manner. There is known a film package referred to as a film package. Such a film package is often used by transferring a bundle of paper stored in a packaging bag to a dedicated dispenser so that dirt and moisture do not adhere to the sanitary paper. On the other hand, if there is no affordable dispenser, if there is no place to install the dispenser, or if the user does not use the dispenser, the bundle of sanitary paper may be used in a packaging bag. (For example, see Patent Document 1).

  Such a packaging bag is provided with a temporary binding portion formed of perforations that can be uniformly broken over substantially the entire length in the longitudinal direction of the packaging bag so that the sanitary paper bundle is conveniently taken out of the packaging bag and transferred to the dispenser. ing. However, even when the sanitary paper is taken out while being stored in the packaging bag, if the temporary binding portion is broken over the entire length and the opening is opened, the sanitary paper remaining in the packaging bag as the sanitary paper is consumed is opened. As the paper decreases and the height of the bundle decreases, the space between the slit on the top of the packaging bag and the top of the sanitary paper bundle increases, and should be consumed next, which should be drawn out in a pop-up manner. There was a problem that the sanitary paper easily fell into the space inside the packaging bag.

  Hereinafter, embodiments for implementing the present invention (hereinafter, embodiments) will be described in detail with reference to the accompanying drawings. Note that the same elements are denoted by the same reference numerals throughout the description of the embodiments.

<First embodiment>
A first embodiment of a film package according to the present invention will be described with reference to FIGS. As shown in FIG. 1, the film package 10 includes a packaging bag 11 formed of a flexible film, and a temporary binding portion 12 provided on the upper surface 11 a of the packaging bag 11 in the longitudinal direction X. As will be described in detail later, the temporary binding section 12 includes left and right end sections 12a, 12a formed by single-line perforations, and a central section 12b formed by single-line perforations.

  First, the packaging bag 11 will be described. The packaging bag 11 is a film packaging bag formed by sealing both ends 11b in the longitudinal direction X with a heat seal or the like in a state where the article to be packaged P is stored inside a tubular flexible film. It is. As shown in FIG. 1, the film packaging bag is formed in a substantially rectangular parallelepiped shape having a gusset, and thus is suitable for storing a bundle of sanitary paper as the article to be packaged P.

  As the flexible film constituting the packaging bag 11, a polyethylene (PE) resin film or a polypropylene (PP) resin film can be suitably used. In addition, this type of packaging bag such as a polyethylene terephthalate resin film can be used. 11 can be used. The flexible film may be a laminated film in which several films are laminated, or may be a film made of a resin mixture of these.

It is preferable that the thickness of the flexible film constituting the packaging bag 11 be 30 to 50 μm as measured according to JIS P8118. When the thickness of the flexible film is less than 30 μm, there is a problem of insufficient strength, and when the thickness exceeds 50 μm, there is a problem of high cost. When a flexible film is formed of a polyethylene (PE) resin film, the basis weight that can secure the above-mentioned thickness is 27.3 to 46.3 g / m ^{2 for} low-density PE and medium-density PE. if 27.8~47.0g / ^{m 2,} a 28.2~48.3g / ^{m 2} if high density PE. Further, when the flexible film is formed of a polypropylene (PP) resin film, the basis weight that can secure the above-mentioned thickness is 26.4 to 45.0 g / m ² in the case of no stretching, and in the case of stretching. the 27.2~45.3g / ^{m 2.}

  As shown in FIG. 2, a packaged object P made of a hygienic paper folded in a pop-up manner is stored inside the packaging bag 11, and has a rectangular parallelepiped shape as a whole. The packaged object P is a sanitary paper such as a tissue paper, a toilet paper, a kitchen paper, a paper hand towel, a paper towel, and a wiper, and may be any of them.

  To briefly explain the pop-up type, the sanitary paper is folded alternately in the vertical direction. When one sanitary paper is taken out, a part of the next sanitary paper is pulled out from the opening for taking out. To fold hygienic paper in a pop-up fashion, ply-up (two sheets) the large-width papermaking base paper as necessary, and then combine a large number of narrow-width rolls cut to a predetermined width to perform folding. The interfolding may be performed by a multi-folding method, in which the base paper of a wide-width papermaking is plied up as required, the roll is cut into a predetermined width, and then folded with one or two narrow-width rolls. The method may be used.

  As general dimensions of the bundle of sanitary paper, the length in the longitudinal direction X is about 180 to 250 mm, the length in the short direction Y is about 80 to 115 mm, and the length in the vertical direction is about 30 to 110 mm. In response to this, the storage space of the packaging bag 11 has a length in the longitudinal direction X of about 105 to 130%, a length in the transverse direction Y of about 100 to 120%, and a vertical It is preferable that the length in the direction is about 100 to 120%. When the length in the longitudinal direction X and the length in the transverse direction Y are within this numerical range, the contact portion between the bundle of sanitary papers and the inside of the packaging bag 11 is reduced, the packaging bag 11 is easily bent, and the bundle of the sanitary papers is bundled. , The position of the opening 13 is easily lowered. If the length in the up-down direction exceeds 120%, the packaging bag 11 is greatly bent before the use of the sanitary paper.

  Next, the temporary binding section 12 will be described. As shown in FIG. 1, the temporary binding portions 12 are provided on the upper surface 11 a of the packaging bag 11 so as to extend from one side to the other side in the longitudinal direction X, and the right and left ends formed by single-line perforations are provided. It is composed of partial sections 12a, 12a and a central section 12b formed by a single line perforation. Here, an example is shown in which the left and right end sections 12a, 12a are provided within the range of the upper surface 11a of the packaging bag 11, but the left and right end sections 12a, 12a are located on the left and right of the upper surface 11a of the packaging bag 11. It may extend to both ends 11b in the longitudinal direction X beyond the end.

  Both the end sections 12a, 12a and the center section 12b can break the perforation by applying a force toward both ends in the short direction Y of the packaging bag 11. As will be described in detail later, the opening 13 may be provided by breaking only the central section 12b as shown in FIG. 3 without breaking the perforated end sections 12a, 12a constituting the temporary binding section 12. it can. In this way, the next sanitary paper that is pulled out after the preceding sanitary paper has been taken out, even if it is stored in the packaging bag 11, may stop in a state where a part thereof is exposed to the outside from the opening 13. As a result, it does not fall into the space inside the packaging bag 11. In addition, the opening here refers to a narrow space formed when a perforation of a single line, such as the end sections 12a, 12a, is broken when formed of a single line, and a cut (or Slit). On the other hand, when a double track is formed as described later, it indicates a wide space such as an opening 13 formed when a perforation of the double track is broken, such as the central section 12b.

  With reference to FIG. 4 and FIG. 5, the temporary binding section 12 of the first embodiment will be described in more detail. As described above, the temporary binding section 12 has left and right end sections 12a, 12a and a center section 12b sandwiched therebetween. The center section 12b further includes a first center section 12b1 closer to the center and left and right ends. There are left and right second central sections 12b2 and 12b2 near the section sections 12a and 12a. In other words, the temporary binding section 12 includes, in order from the left side, a left end section 12a, a left second central section 12b2, a first central section 12b1, a right second central section 12b2, and a right end section 12a. Have been.

  Then, in order to change the easiness of breaking for each of these sections, the tie-cut ratio between the length of the cut portion and the length of the non-cut portion is changed at the perforation forming each section. The second central section 12b2 is set to be most easily broken, and subsequently, the first central section 12b1 and the end section 12a are formed so as to be easily broken. More specifically, when the combination of one cut portion and one non-cut portion is one pitch, one pitch of the second central section 12b2 is equal to the length of the cut portion. The length of the non-cut portion is 2: 1 to 1: 2. Similarly, the pitch of the first central section 12b1 is 1: 1 to 1: 6, and the pitch of the end section 12a is 1: 1 to 7: 1. It is set to 10.

  FIG. 4 does not show the actual dimensions, but indicates that the pitch is different for each section, with the solid line portion of the perforation being a cut portion and the white portion being a non-cut portion. FIG. 5 shows this difference in a more easily understood manner, in which a solid line portion of the perforations is a cut portion and a white line portion is a non-cut portion, and one pitch is compared for each section. Note that the dimensions described in FIG. 5 are numerical values as examples described later, and are not limited to these numerical values.

  By changing the easiness of breakage for each section in this manner, in the first embodiment, for example, in the case where the center section 12 is opened on both sides from the center in the longitudinal direction X, first, the center first center section When 12b1 is broken, the second central sections 12b2, 12b2 at both ends are easily broken subsequently. The right second center section 12b2 and the right end section 12a have a difference in the perforation pitch, that is, the easiness of breakage. Therefore, in normal use, the right second center section 12b2 is followed by the right second center section 12b2. The opening 13 can be formed by breaking only the center section 12 without breaking the end section 12a.

  When the bundle of sanitary paper is taken out of the packaging bag 11 and transferred to a dispenser for use, the left and right end sections 12a, 12a are also broken to form slits, and the central section 12 is formed by breaking. It goes without saying that the temporary binding portion 12 can be opened along with the opening 13 over the entire length in the longitudinal direction X.

<Second embodiment>
Next, a second embodiment according to the present invention will be described. In the second embodiment, as shown in FIG. 6, the central section is formed so as to have a horizontally long hexagonal plane shape by a double-line perforation. Other points are the same as in the first embodiment.

  The central section 12b according to the second embodiment has a horizontally long hexagonal plane shape, and sections corresponding to a pair of left and right two upper and lower sides of the horizontally long hexagon correspond to left and right second central sections 12b2 and 12b2. , The second central section 12b2, 12b2 constitutes a first central section 12b1. A pair of left and right upper and lower sides of a horizontally long hexagon, that is, left and right second central sections 12b2 and 12b2 expand toward the first central section 12b1 and close toward left and right end sections 12a and 12a. I have. Thus, in combination with the change in the pitch of the cut portion and the non-cut portion of the perforation, the left and right second central sections 12b2 and 12b2 serve as a suitable trigger when one of them is first broken, and to the other end. Even if it breaks, the perforations of the end sections 12a, 12a do not continue to break, and the opening 13 can be formed by breaking only the perforations of the central section 12b. That is, the second center section 12b2 on the left is easily broken first, and then the second center section 12b2 on the right is easily broken via the first center section 12b1.

<Third embodiment>
Next, a third embodiment according to the present invention will be described. In the third embodiment, as shown in FIG. 7, the central section is formed so as to have a horizontally long rhombus shape with a double-line perforation. Other points are the same as in the second embodiment.

  The central section 12b according to the third embodiment has a horizontally long rhombic plane shape, and a section corresponding to the left and right ends of two pairs of left and right sides of the horizontally long rhombus is the left and right second central section 12b2. A section sandwiched between the second central section 12b2 and the second central section 12b2 constitutes a first central section 12b1. The left and right ends of each set of two sides on the left and right sides of the horizontally long diamond, that is, the left and right second central sections 12b2 and 12b2, expand toward the first central section 12b1 and move toward the left and right end sections 12a and 12a. It is closed. Thus, in combination with the change in the ratio of the cut portion and the non-cut portion of the perforation, the left and right second central sections 12b2 and 12b2 serve as a suitable trigger when one of them is first fractured, and the other end extends to the other end. Even if it breaks, the perforations of the end sections 12a, 12a do not continue to break, and the opening 13 can be formed by breaking only the perforations of the central section 12b.

<Fourth embodiment>
Next, a fourth embodiment according to the present invention will be described. In the fourth embodiment, as shown in FIG. 8, the central section is formed so as to be elliptical due to perforations of double lines. Other points are the same as in the second embodiment.

  The central section 12b according to the fourth embodiment has a horizontally long elliptical planar shape, and sections corresponding to the left and right circular arcs on the major axis side of the elliptical form include the left and right second central sections 12b2 and 12b2. The section sandwiched between the second central sections 12b2, 12b2 constitutes the first central section 12b1, respectively. The left and right elliptical arcs, that is, the left and right second central sections 12b2 and 12b2 are expanded toward the first central section 12b1 and closed toward the left and right end sections 12a and 12a. Thus, in combination with the change in the ratio of the cut portion and the non-cut portion of the perforation, the left and right second central sections 12b2 and 12b2 serve as a suitable trigger when one of them is first fractured, and the other end extends to the other end. Even if it breaks, the perforations of the end sections 12a, 12a do not continue to break, and the opening 13 can be formed by breaking only the perforations of the central section 12b.

<Fifth embodiment>
Next, a fifth embodiment according to the present invention will be described. In the fifth embodiment, as shown in FIG. 9, the central section is formed so as to be oblong with a double-line perforation. Other points are the same as in the second embodiment.

  The central section 12b according to the fifth embodiment has a horizontally long oval (rounded rectangle) plane shape, and sections corresponding to the left and right circular arcs of the oval are the left and right second central sections 12b2 and 12b2. , The second central section 12b2, 12b2 constitutes a first central section 12b1. The oval left and right arcs, that is, the left and right second central sections 12b2 and 12b2 are expanded toward the first central section 12b1 and closed toward the left and right end sections 12a and 12a. Thus, in combination with the change in the ratio of the cut portion and the non-cut portion of the perforation, the left and right second central sections 12b2 and 12b2 serve as a suitable trigger when one of them is first fractured, and the other end extends to the other end. Even if it breaks, the perforations of the end sections 12a, 12a do not continue to break, and the opening 13 can be formed by breaking only the perforations of the central section 12b.

  The first and second embodiments will be further described using examples 1 and 2, respectively.

<Example 1>
A gusset packaging bag 11 was prepared using a 30 μm thick polyethylene (PE) resin film as a flexible film. For the packaged object P, a paper hand towel (Crecia EF hand towel soft type 200, manufactured by Nippon Paper Crecia Co., Ltd.) was used as a hygienic paper folded in a pop-up manner, and the material was pulp and paper pack recycled pulp. The number and the number of sheets are 200 pairs (400 sheets in total). The size of the bundle of hand towels is 218 mm in the longitudinal direction X, 120 mm in the lateral direction Y, and 70 mm in the vertical direction as a bundle of hand towels. there were. The packaging bag 11 had a length in the longitudinal direction X (distance between both ends 11b) of 280 mm, a length in the short direction Y of 125 mm, and a length in the vertical direction of 75 mm with respect to these sizes.

  On the upper surface 11a of the packaging bag 11, a temporary binding portion 12 made of a straight line according to the first embodiment shown in FIG. 4 is provided. The tie-cut ratio of the length of one cut portion (solid line portion) and one non-cut portion (white line portion) of each section of the temporary binding portion 12 is as shown in Table 1. Two to one and one to two are required for 12b2 for which tearability is required, one to seven and one to ten for 12a where resistance to tear is required, and one to one for 12b1 where intermediate tearability is required. １1 to 6 were each optimal.

  In the temporary binding portion 12 formed of the straight line of the first embodiment, the distance in the longitudinal direction X of the single line perforation forming the central section 12b (that is, the second line on the right side from the boundary between the left end section 12a and the second central section 12b2). The use conditions were tested by changing the distance between the central section 12b2 and the end section 12a) to 40 mm, 50 mm, 65 mm, 80 mm, 90 mm, 110 mm, 140 mm, 170 mm, and 200 mm. As a result of examining the wrapped object P (hand towel or wiper) having a softness of 1.9 to 3.5 g, as shown in Table 2, as shown in Table 2, the longitudinal direction X of the single line perforation forming the central section 12b was determined. When the distance was 65 mm to 80 mm, the taken-out property and the dropping property of the stored sheet were good. On the other hand, when the distance is less than 65 mm, the take-out property is difficult. On the other hand, when the distance exceeds 80 mm, the sheet dropping property is deteriorated.

  Here, the softness as referred to in the present specification is “a resistance value when a 10 cm wide sanitary thin paper is pushed into a gap having a width of 5 mm by a terminal, in a vertical direction and a horizontal direction, by a handle ometer method (JIS L1096: (1999E method) and an average of these values. " In addition, the take-out property is that after 10 sets are taken out, the spread of the opening width is less than 10 mm, and the drop-out property is that when taking out 20 sets, the number of times the sheet has fallen into the packaging bag is 3 times or less. , Respectively. In Table 2, those satisfying these criteria are indicated by Δ, and those not meeting are indicated by ×.

<Example 2>
A packaging bag 11 similar to that of Example 1 was manufactured, and a temporary binding portion 12 formed of a horizontally long hexagon, which is the planar shape of the second embodiment shown in FIG. 6, was provided on the upper surface 11a of the packaging bag 11. The tie-cut ratio of the length of one cut portion (solid line portion) and one non-cut portion (white line portion) of each section of the temporary binding portion 12 is as shown in Table 1.

In the temporary binding portion 12 having a horizontally long hexagonal shape according to the second embodiment, the distance in the short direction Y of the double-line perforation forming the first central section 12b1 is set to 10 mm and 20 mm, and the double-line sewing machine forming the central section 12b. The distance in the longitudinal direction X of the eye (that is, the width from the boundary between the left end section 12a and the second central section 12b2 to the boundary between the right second central section 12b2 and the end section 12a) is 10 mm, 20 mm, 40 mm; The conditions of use were tested by changing to 60 mm and 80 mm. As a result, as shown in Table 3, when the distance in the short direction Y of the double line perforation forming the central section 12b is 10 mm, when the distance (width) in the long direction X is 20, 40, and 60 mm, When the distance in the short direction Y was set to 20 mm, and when the distance (width) in the long direction X was 10 mm and 20 mm, the opening 13 could be provided by smoothly breaking the central section 12b. If caught Horizontal hexagonal virtually as substantially rectangular, the area of a suitable aperture 13 ^becomes 200mm ² ~600mm 2. After taking out the packaged object P, that is, the hand towel as the satellite paper, the stored hand towel was hard to fall into the space inside the packaging bag. In addition, since the take-out property was all good, Table 3 shows the result of only the drop property.

  As described above, the present invention has been described using the embodiment and the example. However, it is needless to say that the technical scope of the present invention is not limited to the range described in the embodiment and the example. It is apparent to those skilled in the art that various changes or improvements can be made to the above embodiment.
