[0007] In the inventions described in Patent Documents 1 and 2 that use paper and plastic film for packages and the like, it cannot be said that means for taking out the packaged item from the package are disclosed. Further, in the invention described in Patent Document 3, even if a rupture line for facilitating the removal of the paper diaper can be obtained, means for easily breaking the packaging bag at the rupture line are not disclosed. Also, the packages and bags described in Patent Documents 1, 2, and 3 use a plastic film at least in part, but no consideration is given to the disposal of the plastic film.

[0008] The present invention aims to facilitate the opening of a sealed bag containing disposable absorbent clothing items such as disposable diapers, and, if the bag is made of paper and plastic film, to facilitate the separation of the paper and plastic film.

[0009] To solve the aforementioned problems, the present invention focuses on a bag that contains and seals multiple wearable items that absorb bodily fluids.

[0010] The bag according to the present invention has vertical, horizontal, and front-to-back directions, at least a portion of the bag is made of paper, and has a top surface and a bottom surface facing each other in the vertical direction, and a circumferential surface formed between the top surface and the bottom surface, and an opening means for the bag is formed on the circumferential surface.

[0011] In one embodiment of the bag according to the present invention, the circumferential portion includes a front portion, a rear portion, and both side portions, and the opening means is formed in at least the front portion and the corner portion interposed between the front portion and the side portion.

[0012] In one embodiment of the bag according to the present invention, the opening means includes a gripping portion formed on the circumferential surface and used for opening the bag.

[0013] In one embodiment of the bag according to the present invention, the wearable articles are stacked inside the bag so as to form at least two upper and lower layers, and the opening means is formed in either a portion corresponding to the boundary between the two upper and lower layers, or in a range of 30 mm width above and below that portion.

[0014] In one embodiment of the bag according to the present invention, when the bag is opened using the opening means, the bag is divided into a portion including the upper section and a portion including the lower section, and the portion of the circumferential surface on which the opening means is not formed acts as a hinge portion, allowing the portion of the bag including the upper section to rotate.

[0015] In one embodiment of the bag according to the present invention, a portion of the bag is formed of paper, and the other portion of the bag is formed of a plastic film, and at least a portion of the paper and at least a portion of the plastic film overlap and are irremovably joined.

[0016] In one embodiment of the bag according to the present invention, the bag is formed from a laminated sheet of paper and a plastic film, and the paper and the plastic film are joined together at either the entire surface where they are in contact with each other or a portion of the surface where they are in contact with each other.

[0017] In one embodiment of the bag according to the present invention, the opening means is one of a single perforation, an annularly extending perforation, an annularly extending half-cut, or an opening tape.

[0018] In one embodiment of the bag according to the present invention, the annular half-cut is formed in the area where the paper and the film overlap, with the paper facing the outer surface of the bag, and inside the half-cut, the film is divided into an upper portion and a lower portion.

[0019] In one embodiment of the bag according to the present invention, a printed area using biomass ink is formed in a section of the paper that is exposed on the circumferential surface.

[0020] In one embodiment of the bag according to the present invention, the area occupied by the one section is less than 10% of the area of ​​the paper exposed in the bag.

[0021] In one embodiment of the bag according to the present invention, after opening by the opening means, traces of the opening means are left on the periphery of the opening, and the plastic film, which does not overlap with the paper, is revealed on the inside of the periphery.

[0022] In one embodiment of the bag according to the present invention, the bodily fluid absorbent wearable article is folded at a bent portion extending in either the lateral direction or the vertical direction intersecting the lateral direction, and a plurality of such wearable articles are stored in the bag in a state where the bent portions face each other.

[0023] In one embodiment of the bag according to the present invention, the bodily fluid absorbent wearable article is a disposable diaper, and the folded portion is located in the crotch area of ​​the diaper.

[0024] In the bag according to the present invention, since at least a portion is made of paper, it is possible to reduce the amount of plastic film used in the bag. The opening means of this bag, such as perforations, includes a gripping portion for the bag, making the opening process easier. Furthermore, since the paper and plastic film in this bag are joined at a portion of the surfaces that come into contact with each other, it is easy to separate the paper from the film.

[0026] The details of the present invention will be described below with reference to the attached drawings.

[0027] Figure 1 is a partially cutaway perspective view of a packaging body 1 including a bag 2 according to the present invention. The packaging body 1 has a bag 2 and contents. The contents are disposable bodily fluid absorbent wearable articles, and the figure shows a plurality of disposable pant-type diapers 3 as an example of disposable bodily fluid absorbent wearable articles.

[0028] In Figure 1, bag 2 is a gusseted bag made of paper containing at least one of kraft pulp and recycled paper pulp, but the gusset is not shown in the figure. Bag 2 has a top portion 6 and a bottom portion 7 that are opposite each other in the vertical direction Y of the figure, and a circumferential portion 8 is formed between these two portions 6 and 7. A hanging portion 10 with a finger insertion hole 9 is formed on the top portion 6. The bottom portion 7 is flat so that the package 1 can be placed on the floor or the like. The circumferential portion 8 is a part that can also be called the body, but in the figure an example formed in the shape of a rectangular tube, and has first and second side portions 11 and 12 that are opposite each other in the horizontal direction X, and a front portion 13 and a rear portion 14 that are opposite each other in the front-to-back direction Z. However, when the package 1 is displayed in a retail store or the like, if there is a side of the package 1 that is to be shown preferentially to the buyer, that side is called the front portion (front side).

[0029] In the illustrated example, there is no particular difference between the front portion 13 and the rear portion 14, and the front portion 13 can be called the rear portion and the rear portion 14 can be called the front portion. In the circumferential direction W of the circumferential portion 8 of the bag 2, the first, second, third, and fourth corner portions 16, 17, 18, and 19 are formed between the first side portion 11 and the front portion 13, between the front portion 13 and the second side portion 12, between the second side portion 12 and the rear portion 14, and between the rear portion 14 and the first side portion 11.

[0030] The pant-type diaper 3 contained in such a bag 2 has a front waist area 21 that covers the body of the diaper wearer, a rear waist area 22, and a crotch area 23, and these areas 21, 22, and 23 form a waist opening 24 and a pair of leg openings 25. The crotch area 23 is folded in half at the fold portion 26. Inside the bag 2, a lower section 27 is formed in which multiple diapers 3 are arranged horizontally X with the fold portion 26 facing upward, and an upper section 28 is formed in which multiple diapers 3 are arranged horizontally X with the fold portion 26 facing downward, and there is a contact area 30 between the fold portions 26 of each other between the lower section 27 and the upper section 28. However, in the present invention, the manner in which absorbent wearable items such as diapers 3 are stored in the bag 2 is not particularly limited. However, depending on the shape and size of the bodily fluid absorbent article, it may be preferable for the article to be folded in a way that extends horizontally or vertically. In addition, it may be preferable for the bodily fluid absorbent articles to be placed in bag 2 with their folded portions facing each other.

[0031] In bag 2, a circumferential perforation 31 extending in the circumferential direction W is formed in the portion corresponding to the contact portion 30 in the lateral direction X and the front-to-back direction Z. The circumferential perforation 31 is an opening means in the present invention, and one example thereof is formed in the front portion 13 and the first and second side portions 11 and 12, as shown in the figure, having a first end 31a in front of the fourth corner 19 or the fourth corner 19, and a second end 31b in front of the third corner 18 or the third corner 18. Bag 2 also has two arrows 61 indicating a gripping portion for opening bag 2. The arrows 61 are printed with biomass ink and are drawn along the second corner 17 and above and below the perforation 31. When the bag 2 is grasped at the second corner 17, which is the portion indicated by arrow 61 or the portion adjacent to arrow 61, and pulled in the direction indicated by arrow 61, it tears along the circumferential perforations 31, separating into an upper portion 51 and a lower portion 52. The arrow acting in this way, i.e., the grasping portion, is an auxiliary means for opening the bag in the present invention. In the illustrated example, the circumferential perforations 31 extend in the circumferential direction of the bag 2, but insofar as the technical effects of the present invention are achieved, the perforations 31 may extend in the vertical direction Y, the horizontal direction X, the front-to-back direction Z, or in directions intersecting these directions.

[0032] Figure 2 is a perspective view of the packaging 1 obtained by rotating the upper portion 51 of the bag 2 in Figure 1 in the direction of arrow Q (see Figure 1). Since the pull-up diapers 3 are neatly arranged in the upper portion 51 and the lower portion 52 with the folded portion 26 facing upwards, each pull-up diaper 3 can be easily removed from the packaging 1.

[0033] Figure 3 is a diagram similar to Figure 1, showing an example of an embodiment. In Figure 3, the bag 2 has an upper gripping portion 62 and a lower gripping portion 63 formed on the front portion 13, more preferably in the lateral central portion of the front portion 13, with a circumferential perforation 31 in between. These gripping portions 62 and 63 are auxiliary means for opening the bag. By pulling the upper gripping portion 62 upward and the lower gripping portion 63 downward, the bag 2 tears at the circumferential perforation 31, bringing the package 1 to the state shown in Figure 2, and the diaper 3 can be removed. The two parallel dashed lines 45a and 45b shown on the bag 2 indicate a preferred range L in the vertical direction Y for creating the circumferential perforation 31 in the bag 2.

[0034] In Figures 1 and 3, the circumferential perforations 31 are formed in the area facing the contact area 30 (see Figure 1) where the folded portions 26 of the lower section 27 and upper section 28 of the diaper 3 meet. However, the circumferential perforations 31 can be moved in the vertical direction Y between the position corresponding to the contact area 30 and the two imaginary lines 45a and 45b. The distance between each of the two imaginary lines 45a and 45b and the circumferential perforations 31 in Figure 3, in other words, the part of the bag 2 corresponding to the contact area 30, is 30 mm.

[0035] Figure 4 shows a cross-section of the line IV-IV in Figure 3. In the bag 2, when the upper gripping portion 62 and the lower gripping portion 63, located above and below the circumferential perforation 31, are pulled in the directions indicated by arrows 62a and 63a, the bag 2 tears at the circumferential perforation 31, and the diaper 3 (see Figure 3) can be removed. In the present invention, the circumferential perforation 31 is not limited to the configuration shown in the figure, and may extend to the rear portion 14.

[0036] Figure 5 is a diagram similar to Figure 3 showing an example of an embodiment of the bag 2 according to the present invention, but the bag 2 in Figure 5 has two parallel circumferential perforations 41 and 42 formed thereon. In the bag 2, the area corresponding to the contact area 30 (see Figure 1) between the diapers 3 is shown by a dashed line, and the circumferential perforations 41 and 42 are formed above and below the dashed line 30a. One end 41a, 42a of each circumferential perforation 41, 42 is located at or in front of the fourth corner 19 of the bag 2, and the other end 41b, 42b is located at or in front of the third corner 18. Ends 41a and 42a are connected by a perforation 43 extending in the vertical direction Y, and ends 41b and 42b are connected via a perforation 44.

[0037] In bag 2, these perforations 41, 41a, 41b, 42, 42a, 42b, 43, and 44 form annular perforations, and a strip-shaped portion 40 is formed inside these annular perforations. A sheet-like gripping portion 40a is attached to the strip-shaped portion 40. The gripping portion 40a is an auxiliary means for opening the bag, and when the gripping portion 40a is pulled in the direction indicated by the arrow 40c, bag 2 tears at the perforations 41, 41a, 41b, 42, 42a, 42b, 43, and 44, the strip-shaped portion 40 is removed from bag 2, and the packaging body 1 can be separated into an upper portion 51 and a lower portion 52 (see Figure 1), making it easy to remove the diaper 3. The two parallel imaginary lines 45a and 45b are in the same positions as the two imaginary lines 45a and 45b in Figure 3, and indicate the range L in Figure 5 where perforations 41 and 42 can be formed. The strip portion 40 is an opening tape, which is one of the opening means in the present invention.

[0038] Note that the bag 2 in Figure 5 may also be configured in a way that does not connect the two circumferential perforations 41 and 42 with a perforation 44. In that case, the strip portion 40 cannot be removed using the perforations. Also, in that case, the circumferential perforations 41 and 42 and the perforation 43 will form a single perforation that forms a horizontal U shape.

[0039] Figures 6(a) and 6(b) show a partially cut perspective view of a packaging body 1 and a cross-sectional view of the perspective view along the line VI(b)-VI(b), illustrating an example of another embodiment of the bag 2 according to the present invention. The packaging body 1 has substantially the same shape as the one illustrated in Figure 5. However, in the packaging body 1 of Figure 6, at least a portion of the circumferential surface 8 of the bag 2 is formed from a laminate sheet 68 of paper 66 and a thermoplastic synthetic resin film 67. In addition, in this bag 2, an annular half-cut 69 is used instead of the perforations 41, 41a, 41b, 42, 42a, 42b, 43, and 44 in Figure 5.

[0040] The half-cut 69 is formed only on the paper 66, and the strip-shaped portion 70 of the paper 66 located inside the half-cut 69 can be peeled off the bag 2 from the film 67. After the strip-shaped portion 70 is removed, a gap 71 where there is no paper 66 is formed in the bag 2 as an opening of the packaging body 1, and the packaging body 1 can be divided into an upper portion 51 and a lower portion 52 (see Figures 1 and 2). In the gap 71, the film 67 is divided into an upper portion 67a and a lower portion 67b, and a perforated portion 72 where there is no film 67 is formed between the upper portion 67a and the lower portion 67b (see Figure 6(b)). Therefore, since the packaging body 1 is divided into an upper portion 51 and a lower portion 52 at the perforated portion 72, it becomes easy to remove the diaper 3 (see Figures 1 and 2). The strip-shaped portion 70 may have an auxiliary means for opening as illustrated in Figures 3 and 5.

[0041] As shown in Figure 6(b), when inserting and removing a finger F from the gap 71, the upper part 67a and lower part 67b of the film 67 may be interposed between the half-cut paper 66 and the finger F, thus preventing the edges 66a and 66b of the paper 66 from touching the finger F and causing injury. The edges 66a and 66b are traces of the half-cut 69, which is the opening mechanism.

[0042] In the laminate sheet 68, the paper 66 and the film 67 are joined at a plurality of joining lines 73 extending parallel to each other. However, the paper 66 and the film 67 may be joined over their entire surfaces. However, if the laminate sheet 68 is as shown in the illustrated example, when separating the paper 66 and the plastic film 67 from the package 1 after use, the separation becomes easier.

[0043] FIG. 7 is also a view similar to FIG. 6 showing another example of an embodiment of the bag 2 according to the present invention. However, in FIG. 7, the bag 2 is formed of paper, and a perforation 31 extending in a ring shape is formed in the bag 2. Inside the perforation 31, a part of the bag 2 is in the form of a strip 70. A strip-shaped covering member 75 made of paper is attached to the outer surface of the strip 70 via joining means (not shown) such as an adhesive. The covering member 75 covers the perforation 31.

[0044] The perforation 31 is formed so as to extend between the third corner 18 and the fourth corner 19, including the first corner 16 and the second corner 17 in the package 1. A preferred covering member 75 covers the perforation 31 and extends beyond at least one of the fourth corner 19 and the third corner 18, facilitating the gripping of either the first or second free end 75a, 75b of the covering member 75.

[0045] As shown in the figure, when the first free end 75a is gripped and the covering member 75 is pulled in the direction indicated by the arrow P to be inverted, the strip 70 joined to the covering member 75 is separated from the bag 2, and a gap 71 is formed in the bag 2. In the package 1, an upper part 51 and a lower part 52 are formed with the gap 71 as a boundary portion, facilitating the removal of a diaper (not shown) (see FIG. 1). In the package 1 of FIG. 7, since the perforation 31 of the bag 2 is covered by the covering member 75, it is possible to prevent dust and the like from entering the inside of the bag 2 from the perforation 31. The strip 70 and the covering member 75 used in this way are the opening tape in the present invention. Also, the end 75a is an auxiliary means for opening in the present invention.

[0046] Figure 8 is a perspective view of the package 1 obtained by rotating the upper portion 51 of the package 1 in FIG. 7 in the direction of arrow Q. When rotating the upper portion 51, a part 14a of the rear surface portion 14 of the bag 2 acts as a hinge. In each of the upper portion 51 and the lower portion 52 in the illustrated example, unlike the package 1 in FIG. 2, the bent portion 26 (see FIG. 1) of the diaper 3 protrudes from the bag 2, so that it is particularly easy to take out the diaper 3.

[0047] FIG. 9 is a view similar to FIG. 7 showing another example of another embodiment of the bag 2 according to the present invention, but the illustration of the diaper is omitted.

[0048] The bag 2 of the package 1 in FIG. 9 has a top portion 6, a bottom portion 7, and a peripheral surface portion 8. The top portion 6 has a hanging portion 6a extending downward in the vertical direction Y covering the upper portion 8a of the peripheral surface portion 8 to form an upper edge portion 100 on the peripheral surface portion 8. At the upper edge portion 100, the hanging portion 6a and the upper portion 8a overlap so that the upper portion 8a is on the inside and the hanging portion 6a is on the outside.

[0049] In this bag 2, the top portion 6 is formed of a thermoplastic synthetic resin film such as polyethylene, while the peripheral surface portion 8 and the bottom portion 7 are formed of paper. At the upper edge portion 100, the upper portion 8a and the hanging portion 6a are joined inseparably by using an adhesive 102 such as a hot melt adhesive or by partially melting and crimping the hanging portion 6a. A finger insertion hole 9 is formed in the top portion 6 by punching a plastic film under heating.

[0050] In the bag 2, an annular perforation 31 similar to the example in FIG. 7 is formed immediately below the upper edge portion 100. A covering member 75 covers the perforation 31, and the covering member 75 is joined inseparably to the peripheral surface portion 8 through joining means (not shown) such as adhesion inside the perforation. When either of the first and second free end portions 75a, 75b of the covering member 75 is inverted and pulled in the direction indicated by arrow P, the paper inside the perforation 31 comes off the bag 2 to form a gap portion 71, while the top portion 6 and the peripheral surface portion 8 of the bag 2 are connected at the rear surface portion 14 of the peripheral surface portion 8.

[0051] Figure 10 shows the top portion 6 in Figure 9 reciprocating and pivoting in the direction indicated by the double-headed arrow R, allowing the top opening 101 formed in the packaging body 1 to be opened and closed, although the diapers 3 are not shown. The top portion 6 acts as an openable and closable lid in the packaging body 1, preventing dust and other debris from entering the inside of the packaging body 1. After all the diapers 3 in the packaging body 1 have been used, the top portion 6 and the surrounding portion 8 can be separated at the rear portion 14 of the surrounding portion 8 using scissors or the like. The top portion 6 can then be disposed of as plastic waste, while the surrounding portion 8 and the bottom portion 7 can be reused as pulp raw materials or disposed of as combustible waste.

[0052] In the packaging 1 shown in Figure 9, a printed area 105 is also formed on the paper of the front portion 13. The printed area 105 in the illustrated example includes printed characters A, B, C, 1, 2, and 3, and is within the rectangular area indicated by the dashed line 106. The dashed line 106 extends horizontally and vertically, touching the outermost characters in the vertical Y direction and horizontal X direction when the packaging 1 is held almost perpendicular to a horizontal plane (not shown). In this invention, biomass ink is used for the printed characters, and the area of ​​the printed area 105 is kept to less than 10% of the area of ​​paper exposed in the bag. The packaging 1 and bag 2 according to the present invention are thus environmentally conscious.

[0053] In the present invention, disposable absorbent wearable items, such as the disposable pull-up diaper 3, include not only disposable pull-up diapers but also open-type diapers, training pants, pants for incontinence patients, sanitary napkins, incontinence pads, breast pads, etc. These absorbent wearable items can be stored in the bag 2 not only by folding them in half as shown in the illustrated example, but also by folding them into three or four sections, or without folding them. Furthermore, the absorbent wearable items in the lower section 27 and upper section 28 can be placed with their folded portions 26 facing each other as shown in the illustrated example, or with the waist openings 24 (see Figure 1) of the pull-up diaper 3 facing each other. Moreover, the wearable items can be stored in the bag 2 lying horizontally X, rather than stacked vertically.
