[The problem the invention is trying to solve]

The inventions described in Patent Documents 1 and 2, which use paper and plastic films for packaging, etc., cannot be said to disclose a means for opening the packaged object from the packaging. Moreover, in the invention described in Patent Document 3, even if a tear line for easily taking out a disposable diaper is obtained, there is no disclosure of a means for easily tearing the packaging bag at the tear line. Moreover, although the packaging and bags described in Patent Documents 1, 2, and 3 use plastic films in at least a portion, there is no concern about the disposal of the plastic films.

The subject of the present invention is to provide a sealed bag for storing disposable body fluid absorbent wearable articles such as disposable diapers, so that the bag can be easily opened and, when paper and plastic films are used in the bag, the paper and plastic films can be easily separated. [Technical means for solving the problem]

In order to solve the above-mentioned problems, the present invention is directed to a sealed bag for storing a plurality of body fluid absorbent wearing articles.

The bag of the present invention is characterized in that the bag has an up-down direction, a lateral direction and a front-back direction, at least a part of the bag is formed by paper, and has a top face portion and a bottom face portion opposite to each other in the up-down direction, and a peripheral face portion formed between the top face portion and the bottom face portion, and a means for opening the bag is formed on the peripheral face portion.

In one embodiment of the bag of the present invention, the peripheral surface portion includes a front portion, a rear portion, and two side portions, and the opening means is formed at least at any one of the corners between the front portion and the side portions.

In one embodiment of the bag of the present invention, the opening means includes a gripping portion formed on the peripheral surface portion for opening the bag.

One of the embodiments of the bag of the present invention is that the wearable articles are stacked on the inner side of the bag to form at least two sections, upper and lower, and the opening means is formed at a position corresponding to the boundary of the upper and lower sections, and at any position within a width range of 30 mm above and below the position.

One of the implementation forms of the bag of the present invention is that, when the bag is opened using the opening means, the bag is separated into a portion including the upper section and a portion including the lower section, and a portion of the peripheral surface where the opening means is not formed serves as a hinge portion, allowing the portion including the upper section of the bag to rotate.

One embodiment of the bag of the present invention is that a portion of the bag is formed by the paper, and the other portion of the bag is formed by a plastic film, and at least a portion of the paper and at least a portion of the plastic film overlap and are inseparably joined.

One embodiment of the bag of the present invention is that the bag is formed by a laminated sheet of the paper and the plastic film, and the paper and the plastic film are joined at either the entirety of the surfaces in contact with each other or a portion of the surfaces in contact with each other.

In one embodiment of the bag of the present invention, the aforementioned opening means is any one of a single perforation line, a perforation line extending in a ring shape, a half-cut extending in a ring shape, and an opening tape.

One of the embodiments of the bag of the present invention is that the aforementioned annularly extending half-cut is formed at the overlapping portion of the aforementioned paper and the plastic film with the aforementioned paper as the outer side of the aforementioned bag, and on the inner side of the aforementioned half-cut, the aforementioned plastic film is divided into an upper portion and a lower portion.

In one embodiment of the bag of the present invention, a printing portion using bio-ink is formed in an area of the paper exposed on the peripheral surface.

In one embodiment of the bag of the present invention, the area occupied by the region is less than 10% of the area of the paper exposed in the bag.

In one embodiment of the bag of the present invention, after being opened by the opening means, a trace of the opening means is produced around the opening, and the plastic film is exposed inside the periphery without overlapping with the paper.

One of the embodiments of the bag of the present invention is that the aforementioned absorbent wearing article is folded at a bend extending in either a transverse direction of the aforementioned absorbent wearing article or a longitudinal direction intersecting the transverse direction, and a plurality of the aforementioned wearing articles are stored in the aforementioned bag in a state where they are stacked with the aforementioned bends facing each other.

One of the embodiments of the bag of the present invention is that the aforementioned body fluid absorbent wearable article is a disposable diaper, and the aforementioned folded portion is located in the crotch region of the aforementioned diaper. [Effect of the invention]

In the bag of the present invention, since at least a part is formed of paper, the amount of plastic film used in the bag can be reduced. The opening means such as the perforated line in the bag makes the opening operation easy by including a gripping portion for the bag. In addition, the paper and the plastic film in the bag are joined at a part of the mutually contacting surfaces, making it easy to sort the paper and the plastic film.

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

FIG1 is a partially broken perspective view of a package 1 including a bag 2 of the present invention. The package 1 has a bag 2 and a contained object. The contained object is a disposable body fluid absorbent wearable article, and the figure shows a plurality of disposable shorts-type paper diapers 3 as an example of the disposable body fluid absorbent wearable article.

In FIG. 1 , the bag 2 is a corner-supported bag formed by paper containing at least one of kraft pulp and old paper pulp, but the illustration of the corner plate is omitted in the figure. The bag 2 has a top portion 6 and a bottom portion 7 that are opposite to each other in the vertical direction Y of the figure, and a peripheral portion 8 is formed between the two portions 6 and 7. A hanging portion 10 having a finger insertion hole 9 is formed on the top portion 6. The bottom 7 is formed to be flat so that the packaging body 1 can be placed on the ground or the like. Although the peripheral portion 8 can also be called a main body portion, the figure shows an example of forming a square tube shape, with first and second side portions 11 and 12 that are opposite to each other in the horizontal direction X, and a front portion 13 and a rear portion 14 that are opposite to each other in the front-rear direction Z. However, when the package 1 is displayed in a small vendor's store or the like, if the side that the purchaser wants to see first is on the package 1, that side is called the front side (front side).

In the example shown in the figure, there is no particular difference between the front part 13 and the rear part 14, and the front part 13 can be referred to as the rear part, and the rear part 14 can be referred to as the front part. In the circumferential direction W of the peripheral part 8 of the bag 2, the first, second, third, and fourth corners 16, 17, 18, and 19 are formed between the first side part 11 and the front part 13, between the front part 13 and the second side part 12, between the second side part 12 and the rear part 14, and between the rear part 14 and the first side part 11.

The shorts-type paper diaper 3 as the storage item in the bag 2 has a front waist region 21, a rear waist region 22, and a crotch region 23 covering the body of the paper diaper wearer, and the waist opening 24 and a pair of leg openings 25 are formed by the regions 21, 22, 23. The crotch region 23 is folded in half at the bend 26. Inside the bag 2, there is a lower section 27 in which a plurality of paper diapers 3 are arranged in the transverse direction X with the bend 26 facing upward, and an upper section 28 in which a plurality of paper diapers 3 are arranged in the transverse direction X with the bend 26 facing downward, and there is a portion 30 between the lower section 27 and the upper section 28 where the bends 26 contact each other. However, in the present invention, the manner in which the bodily fluid absorbent garment such as the disposable diaper 3 is stored in the bag 2 is not particularly limited. However, depending on the shape and size of the bodily fluid absorbent garment, it is desirable to fold the garment with a so-called fold extending in the lateral direction or in the longitudinal direction. In addition, it is desirable to store the bodily fluid absorbent garment in the bag 2 with the folds facing each other.

In the bag 2, a circumferential perforation line 31 extending in the circumferential direction W is formed in the portion corresponding to the contact portion 30 in the transverse direction X and the front-rear direction Z. The circumferential perforation line 31 is a means for opening the bag in the present invention. As shown in the figure, one example is formed on the front portion 13 and the first and second side portions 11 and 12, and has a first end 31a at the fourth corner 19 or just in front of the fourth corner 19, and has a second end 31b at the third corner 18 or just in front of the third corner 18. In the bag 2, two arrow marks 61 are used to indicate a gripping portion for opening the bag 2. The arrow marks 61 are printed with bio-ink, along the second corner 17, and are drawn above and below the perforation line 31. The bag 2 is torn into an upper part 51 and a lower part 52 at the circumferential perforation line 31 by grasping the part with the arrow mark 61 or the second corner 17 of the part adjacent to the arrow mark 61 and pulling in the direction indicated by the arrow mark 61. The arrow mark, i.e., the gripping part, is an auxiliary means for opening in the present invention. In addition, although the circumferential perforation line 31 in the example shown in the figure extends in the circumferential direction of the bag 2, the perforation line 31 may also extend in the up-down direction Y, the lateral direction X, the front-back direction Z, and directions intersecting these directions as long as the technical effect of the present invention can be achieved.

Fig. 2 is a perspective view of the package 1 in which the upper portion 51 of the bag 2 in Fig. 1 can be rotated in the direction of arrow Q (see Fig. 1). Since the shorts-type paper diapers 3 are neatly arranged with the folded portion 26 at the top in the upper portion 51 and the lower portion 52, the shorts-type paper diapers 3 can be easily taken out of the package 1 one by one.

FIG. 3 is a diagram similar to FIG. 1 showing an example of an embodiment. In the bag 2 shown in FIG. 3 , an upper gripping portion 62 and a lower gripping portion 63 are formed in the front portion 13, more preferably in the transverse central portion of the front portion 13, sandwiching the circumferential perforation line 31. The gripping portions 62 and 63 are auxiliary means for opening. If the upper gripping portion 62 is pulled upward and the lower gripping portion 63 is pulled downward, the bag 2 is torn at the circumferential perforation line 31, and the package body 1 is made into the state of FIG. 2, and the paper diaper 3 can be taken out. The two imaginary lines 45a and 45b parallel to each other shown in the bag 2 represent the range L in the up-down direction Y in which the circumferential perforation line 31 is preferably formed in the bag 2.

Although the circumferential perforation line 31 in Figs. 1 and 3 is formed at a position facing the contact portion 30 (see Fig. 1) between the bent portions 26 of the lower section 27 and the upper section 28 of the diaper 3, the circumferential perforation line 31 can move between the position corresponding to the contact portion 30 and the two imaginary lines 45a and 45b in the vertical direction Y. The distance between each of the two imaginary lines 45a and 45b and the circumferential perforation line 31 in Fig. 3, that is, the position corresponding to the contact portion 30 in the bag 2, is 30 mm.

FIG4 is a cross-sectional view taken along line IV-IV of FIG3. In the bag 2, if the upper gripping portion 62 and the lower gripping portion 63 located above and below the circumferential perforation line 31 are pulled in the directions indicated by arrows 62a and 63a, respectively, the bag 2 is torn at the circumferential perforation line 31, and the paper diaper 3 can be taken out (see FIG3). In the present invention, the circumferential perforation line 31 is not limited to the embodiment shown in the figure, and may also extend to the rear face portion 14.

FIG. 5 is similar to FIG. 3 showing an example of an embodiment of the bag 2 of the present invention, but the bag 2 of FIG. 5 is formed with two circumferential perforations 41 and 42 parallel to each other. In the bag 2, the circumferential perforations 41 and 42 are formed at locations corresponding to the contact locations 30 (see FIG. 1 ) of the paper diapers 3 indicated by imaginary lines. One end 41a and 42a of each of the two ends of the circumferential perforations 41 and 42 above and below the imaginary line 30a is located just in front of the fourth corner 19 or the fourth corner 19 of the bag 2, and the other end 41b and 42b is located just in front of the third corner 18 or the third corner 18. The ends 41a and 42a are connected at a perforation line 43 extending in the vertical direction Y, and the ends 41b and 42b are connected via a perforation line 44.

In the bag 2, the perforation lines 41, 41a, 41b, 42, 42a, 42b, 43, 44 form a perforation line extending in a ring shape, and a strip-shaped portion 40 is formed inside the perforation line extending in a ring shape. A thin sheet-shaped gripping portion 40a is mounted on the strip-shaped portion 40. The gripping portion 40a is an auxiliary means for opening. If the gripping portion 40a is pulled in the direction indicated by the arrow mark 40c, the bag 2 is torn at the perforation lines 41, 41a, 41b, 42, 42a, 42b, 43, 44. By removing the strip-shaped portion 40 from the bag 2, the package body 1 can be separated into an upper portion 51 and a lower portion 52 (see FIG. 1), so that the paper diaper 3 can be easily taken out. The two parallel imaginary lines 45a, 45b are not located at the same position as the two imaginary lines 45a, 45b in Fig. 3, and indicate the range L in which the perforation lines 41, 42 in Fig. 5 can be formed. The strip portion 40 is a tearing strip of the tearing means in the present invention.

In addition, the bag 2 of FIG. 5 may be in a state where the two circumferential perforated lines 41 and 42 are not connected by the perforated line 44. In this case, the bag 2 is such that the belt portion 40 cannot be removed by the perforated line. In this case, the circumferential perforated lines 41 and 42 and the perforated line 43 form a single perforated line in a horizontal U shape.

Fig. 6 (a) and (b) show a partially broken three-dimensional view of a package body 1 and a cross-sectional view of the line VI (b) -VI (b) of the three-dimensional view of another embodiment of the bag 2 of the present invention. The package body 1 has almost the same shape as that shown in Fig. 5. However, at least a part of the peripheral surface 8 of the bag 2 in the package body 1 of Fig. 6 is formed by a laminated sheet 68 of paper 66 and a thermoplastic synthetic resin film 67. In addition, in the bag 2, a half cut 69 extending in an annular shape is used instead of the perforated lines 41, 41a, 41b, 42, 42a, 42b, 43, 44 in Fig. 5.

The half cut 69 is formed only for the paper 66, and the paper 66 can be removed from the bag 2 by peeling off the strip 70 of the paper 66 located on the inner side of the half cut 69 from the film 67. In the bag 2 after the strip 70 is removed, a gap 71 where the paper 66 does not exist is formed as an opening of the package 1, and the package 1 can be divided into an upper part 51 and a lower part 52 (see Figures 1 and 2). In the gap 71, the film 67 is separated into an upper part 67a and a lower part 67b, and a through hole 72 where the film does not exist is formed between the upper part 67a and the lower part 67b (see Figure 6 (b)). Therefore, since the package 1 is separated into the upper part 51 and the lower part 52 at the through hole 72, it is easy to take out the paper diaper 3 (see Figures 1 and 2). The strip-shaped portion 70 may also include an auxiliary means for opening as shown in FIGS. 3 and 5 .

As shown in FIG6(b), when the finger F is inserted or pulled out of the gap 71, the upper portion 67a and the lower portion 67b of the film 67 are sandwiched between the half-cut paper 66 and the finger F, so that the finger F is prevented from contacting the edges 66a and 66b of the paper 66 and hurting the finger F. The edges 66a and 66b are traces of the half-cut 69 as the opening means.

In the laminated sheet 68, the paper 66 and the film 67 are joined at a plurality of joint lines 73 extending parallel to each other, but the paper 66 and the film 67 may be joined to each other on the entire surface. However, if the laminated sheet 68 is as shown in the figure, it is easier to sort the paper 66 and the plastic film 67 when sorting the used packaging body 1.

FIG. 7 is also a figure similar to FIG. 6 showing an example of still another embodiment of the bag 2 of the present invention. However, in FIG. 7 , the bag 2 is formed of paper, and a ring-shaped perforation line 31 is formed in the bag 2. Inside the perforation line 31, a part of the bag 2 is in the shape of a so-called strip-shaped portion 70. On the outside of the strip-shaped portion 70, a strip-shaped covering member 75 formed of paper is attached via a bonding means (not shown) such as an adhesive. The covering member 75 covers the perforation line 31.

The perforation line 31 includes the first corner 16 and the second corner 17 of the package body 1 and is formed so as to extend between the third corner 18 and the fourth corner 19. The covering member 75 preferably covers the perforation line 31 and extends across at least one of the fourth corner 19 and the third corner 18, so that it is easy to grasp any of the first and second free ends 75a, 75b of the covering member 75.

As shown in the figure, if the first free end 75a is pinched and the covering member 75 is pulled in the reverse direction indicated by the arrow P, the strip portion 70 joined to the covering member 75 is cut off from the bag 2, and a gap portion 71 is formed in the bag 2. In the package 1, the upper portion 51 and the lower portion 52 are formed with the gap portion 71 as a boundary portion, so that the paper diaper (not shown) can be easily taken out (refer to Figure 1). In the package 1 of Figure 7, since the perforated line 31 of the bag 2 is covered with the covering member 75, it is possible to prevent garbage and the like from invading the inside of the bag 2 through the perforated line 31. The strip portion 70 and the covering member 75 used in this way are the unsealing tape in the present invention. In addition, the end 75a is an auxiliary means for unsealing in the present invention.

FIG8 is a perspective view of the package 1 in FIG7 in which the upper portion 51 of the package 1 can be rotated in the direction of the arrow Q. When the upper portion 51 is rotated, a portion 14a of the rear portion 14 of the bag 2 functions as a hinge. The upper portion 51 and the lower portion 52 of the example shown in the figure are different from the package 1 in FIG2. Since the bent portion 26 (see FIG1) of the paper diaper 3 protrudes from the bag 2, it is particularly easy to take out the paper diaper 3.

FIG. 9 is the same diagram as FIG. 7 showing another example of the bag 2 of the present invention, but the illustration of the paper diaper is omitted.

Although the bag 2 of the package body 1 in FIG. 9 has a top portion 6, a bottom portion 7, and a peripheral portion 8, the upper portion 8a of the peripheral portion 8 is covered by a hanging portion 6a extending downward from the top portion 6 in the vertical direction Y to form an upper edge portion 100 in the peripheral portion 8. At the upper edge portion 100, the hanging portion 6a and the upper portion 8a are overlapped in a manner such that the upper portion 8a is on the inner side and the hanging portion 6a is on the outer side.

In the 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 100, the upper portion 8a and the hanging portion 6a are non-separably bonded using an adhesive 102 such as a hot melt adhesive or by melting and pressing the hanging portion 6a. The top portion 6 is formed with a finger insertion hole 9 by punching the plastic film under heating.

In the bag 2, a ring-shaped perforated line 31 similar to the example of FIG. 7 is formed just below the upper edge 100, and the covering member 75 covers the perforated line 31 and is inseparably joined to the peripheral surface 8 on the inner side of the perforated line by a joining means such as bonding (not shown). When one of the first and second free ends 75a, 75b of the covering member 75 is reversed and pulled in the direction indicated by the arrow mark P, the paper on the inner side of the perforated line 31 falls off from the bag 2 to form the gap 71, and the top 6 of the bag 2 and the peripheral surface 8 are connected together at the rear surface 14 of the peripheral surface 8.

FIG10 shows a state in which the top portion 6 in FIG9 rotates back and forth in the direction indicated by the double-headed arrow R and an openable and closable top opening 101 is formed in the package body 1, but the illustration of the paper diaper 3 is omitted. The top portion 6 functions as an openable and closable lid in the package body 1 to prevent dust and the like from invading the inner side of the package body 1. After the paper diaper 3 in the package body 1 is completely used, if the rear portion 14 of the peripheral portion 8 is cut apart from the top portion 6 and the peripheral portion 8 by scissors, the top portion 6 can be disposed of as plastic waste, and the peripheral portion 8 and the bottom portion 7 can be recycled as pulp raw materials or disposed of as combustibles.

In the package body 1 of FIG9 , a printing portion 105 is formed on the paper of the front portion 13. The printing portion 105 shown in the example includes printed characters A, B, C, 1, 2, 3, and is within the range of a rectangle represented by an imaginary line 106. The imaginary line 106 extends horizontally and vertically in the up-down direction Y and the lateral direction X when the package body 1 is erected in a direction substantially perpendicular to a horizontal plane (not shown) and contacts the characters at the outermost side. In the present invention, bio-ink is used for printing characters, and the area of the printing portion 105 can be suppressed to be less than 10% of the area of the paper exposed in the bag. The package body 1 and the bag 2 of the present invention are thus environmentally friendly.

In the present invention, the disposable bodily fluid absorbent garments, which take the disposable panty-type diaper 3 as an example, include, in addition to the disposable panty-type diaper, unfolded diapers, training pants, underwear for incontinent patients, sanitary napkins, incontinence pads, breast milk pads, etc. The bodily fluid absorbent garments can be stored in the bag 2 in a folded state, a folded state, a folded state, or a folded state, in addition to being folded in half as shown in the example. In addition, the bodily fluid absorbent garments of the lower section 27 and the upper section 28 can be placed in a folded state with the bent portion 26 facing each other as shown in the example, or facing each other at the waist opening 24 (see FIG. 1 ) of the panty-type diaper 3. Furthermore, instead of stacking the wearable articles in the vertical direction, the wearable articles can be stored in the bag 2 in a state of lying in the horizontal direction X.
