However, when these packaging bags according to the prior art are used, it is easy to take out the absorbent article. However, the packaging bag after removing the top surface has a large opening, and the article is contaminated with dust or the like. However, there was a problem that the contents were easily popped out due to a fall and the portability was poor.
Therefore, a main problem of the present invention is to provide a packaging bag for absorbent articles that can be easily taken out and can maintain good portability even when the remaining number of absorbent articles in the packaging bag is reduced. It is to provide.

  The present invention that has solved the above problems is as follows. In addition, the “cut line” in the present invention indicates a line formed by a perforation, a cut, or the like that is cut off during use. The “cut line” is a line including one or both of the cut line and the already separated line formed by a slit or the like. Further, in the packaging bag according to the present invention, each direction is defined as the “upper surface portion” as the surface on which the take-out port is arranged regardless of the actual distribution and use state.

<Invention of Claim 1>
A packaging bag for absorbent articles in the form of a hexahedron having an upper surface portion, a bottom surface portion, and four side surfaces, in which the absorbent article is housed in a plurality of layers in the vertical direction.
The upper surface portion has a cut line for forming a take-out port,
It has a valley fold position along the circumferential direction in the middle in the up-down direction of the side surface portion, and a mountain fold position along the circumferential direction spaced apart upward or downward with respect to the valley fold position,
At least an adhesive portion covered with a peeling portion between the mountain fold position and the valley fold position, or between a position that is line-symmetric with the mountain fold position and the valley fold position with respect to the valley fold position. Have
The side surface portion is folded in each direction at the mountain fold position and the valley fold position, and the portion between the mountain fold position and the valley fold position of the side surface portion is folded between the upper and lower side portions, and the peeling is performed. The side surface portion is peeled off by adhering a portion between the mountain fold position and the valley fold position and a portion opposite to the side fold position through the adhesive portion exposed thereby. Configured to hold the folded state,
A packaging bag for absorbent articles.

(Function and effect)
When the absorbent article is stored in a plurality of layers in the vertical direction, the take-out port is preferably formed as a cut line having the same length parallel to the long side of the upper surface portion. Since the take-out port is linear, it is possible to prevent dust and the like from adhering to the absorbent article inside after opening the packaging bag. In addition, by setting the length to be the same as the long side of the upper surface portion, it is possible to secure an opening sufficient for taking out the article.

  When the packaging bag of such a form is used, if the remaining number of absorbent articles decreases, a gap will be formed in the upper part of the packaging bag, making it difficult to take out the article. In order to reduce this gap, it is necessary to reduce the height of the packaging bag. In the present invention, a part of the side portion of the packaging bag can be folded inside, and the height of the packaging bag can be reduced by providing an adhesive portion for holding the folded state. . Thereby, the distance from the taking-out opening of the upper part of a packaging bag to the absorbent article with which the remaining number decreased can be shortened.

  In patent document 1, although the height of a packaging bag is made low by removing a packaging bag upper surface part and a part of side part, in this case, an upper opening will become large. On the other hand, in the present invention, since the upper surface portion of the packaging bag is not removed, it is possible to reduce the height of the packaging bag without widening the upper opening.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, the form using the sanitary napkin individually packaged as an absorbent article is illustrated.

(First embodiment)
FIG. 1 is a perspective view showing a sanitary napkin packaging bag according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a state in which a side portion is folded during use.
The packaging bag 1 is preferably manufactured from a flexible thin sheet material. The material constituting the packaging bag 1 can be paper, non-woven fabric, resin or the like, and is not limited, but in particular, a resin film (polyethylene film, polypropylene film or the like) is preferably used. In the case of using a resin film, a printing unit 2 is usually provided which is colored so as to be opaque so that the contents of the packaging bag 1 are not visually recognized from the outside, and a product name and other necessary items are printed on the wall.

  The top surface portion 11 and the bottom surface portion 12 of the packaging bag 1 are heat-sealed and ultrasonically formed so that the resin film has a gusseted bag shape having folding portions 17 at both ends of the sealing wire 16 along the sealing wire 16. It is formed by sealing with welding, adhesive or the like. The side portion of the packaging bag 1 includes a front panel 13, a rear panel 14 that faces the front panel 13, two side panels 15 that connect the front panel 13 and the rear panel 14. The front panel 13, the rear panel 14, and the side panel 15 are substantially planar as shown in FIG.

  FIG. 1 discloses a form in which sanitary napkins 100 folded into flat rectangles and individually wrapped are stacked in a row parallel to the bottom surface portion 12. There is no particular limitation as long as it has at least two layers in the vertical direction. Two layers may be stacked (FIG. 10), or a layer parallel to the bottom surface formed by vertically overlapping the napkin 100 on the bottom surface portion may be stacked twice or more than three layers (FIG. Double lamination).

  On the upper surface portion of the packaging bag 1, a takeout opening cut line 18 is formed. Although the cut line can be formed by a perforation line, a cut line, or the like, it is particularly desirable that the cut-out line for the outlet is a perforation line. The shape of the cut-out line 18 for the take-out port is not particularly limited as long as a take-out port having a size that can be taken out without deforming the sanitary napkin 100 is formed. A straight line is more preferable. By making the take-out port linear, it is possible to prevent dust and the like from adhering to the internal sanitary napkin even after the packaging bag 1 is opened. Moreover, by using a cut line having the same length as the side of the upper surface part, an opening sufficient for taking out the article can be secured.

  The packaging bag 1 has a mountain fold position and a valley fold position along the circumferential direction on the side surface portion. Either the mountain fold position or the valley fold position may be arranged on the upper side, but the mountain fold position is preferably arranged on the upper side. There is no need to place a mark at the mountain fold position or the valley fold position, but an auxiliary line formed with printed guidelines, perforations, fold lines, etc. (mountain fold assist) so that the user can easily confirm the position. It is more preferable to arrange the line 21 and the valley fold auxiliary line 22). It is preferable that the mountain fold auxiliary line 21 and the valley fold auxiliary line are circularly arranged in the horizontal direction on the side surface portion. A portion above the mountain fold auxiliary line 21 of the packaging bag 1 is a top portion T, a portion below the valley fold auxiliary line 22 is a bottom portion B, and a portion between the mountain fold auxiliary line and the valley fold auxiliary line is an intermediate portion M. . Both the auxiliary lines 21 and 22 are arranged such that the vertical lengths of the top portion T and the bottom portion B are equal to or greater than the vertical length of the intermediate portion M. The packaging bag 1 is formed by folding the resin sheet on the side surface portion according to the mountain fold auxiliary line 21 and the valley fold auxiliary line 22 and holding the folded state (details of the holding method will be described later), FIG. As shown in FIG. In FIG. 2, in the bottom portion B, a portion hidden by the side surface sheet of the top portion T is defined as a bottom upper portion BH, and a portion that is not hidden is defined as a bottom lower portion BL.

  The printing part 2 of the packaging bag 1 is preferably arranged in the intermediate part M and / or the bottom upper part BH. When carrying a sanitary napkin, the user often puts it in a cosmetic pouch or the like so as not to know what the contents are. Although the folded package is excellent in portability, it is difficult to use it as a portable sanitary napkin when the product name is visible from the outside. By arranging the printing part 2 in the intermediate part M and / or the bottom upper part BH, as shown in FIG. 2, when folded according to the auxiliary lines 21 and 22, the printing part is hidden. The package in such a form has a structure in which the product name can be seen from the outside when the product is distributed, and the product name cannot be seen from the outside when used.

  The front panel 13, the rear panel 14, and the side panel 15 that form the side surface of the packaging bag 1 have at least an intermediate portion M between two surfaces (for example, the front panel 13 and the rear panel 14) that face each other. A peeling portion 52 surrounded by a cutting line 51 such as a perforation or a slit is provided. As shown in FIG. 1, the peeling portion 52 can be appropriately selected from a form that circulates in the horizontal direction so as to cover all four sides of the side face part, a form that is arranged in plural on each face, etc. It is preferably an elongated form. In the case where one peeling part is arranged on each of the two opposing side surfaces, it is preferable that the two peeling parts 52 are targeted with respect to the center of the horizontal cross section of the packaging bag 1 (FIG. 12).

  The adhesive portion 53 is exposed in the opening after the separation portion is separated and / or separated according to the cutting line 51. The peeling part before and behind peeling, the front of a adhesion part, and the partially expanded view of a cross section are shown to FIG. The cutting line 51 may be a cutting line that is cut when a perforation or the like is used, or a separation line in which both members that already sandwich the line are separated, such as a slit line. When the perforation is used, there is little fear of peeling during transportation, but the perforation must be cut off during use, and the resin sheet constituting the packaging bag 1 is a material that is easy to extend (for example, polyethylene) The perforation and separation of the peeling portion 52 from the packaging bag 1 are likely to be difficult. On the other hand, when the slit line is used, the peeling can be easily performed as compared with the perforation, but the peeling portion is held in the package by the adhesive portion 53, and thus the adhesive strength of the adhesive portion 53 is weak. In some cases, there is a risk of peeling and dropping during transportation. Therefore, it is desirable that the shape of the cutting line is appropriately selected in consideration of the properties of the resin sheet to be used, an adhesive, and the like. At least one end of each peeling portion is trimmed into a shape such as a semicircle, an anti-ellipse, or a trapezoid, so that it is easy for the user to pick up with a finger during separation / peeling (FIG. 5A) .

  Inside the peeled portion, a release treatment portion 54 in which a release agent such as silicone, long chain alkyl polymer, polyolefin, alkyd resin, fluorine compound or the like is applied in a layer shape, a thin film shape, or a mesh shape is disposed. It is preferable (FIG. 5C).

  An adhesive part sheet 55 that is slightly larger than the peeling part is laminated inside the side surface part of the package so as to cover the whole peeling part. The pressure-sensitive adhesive sheet 55 may be fixed to the side surface by heat sealing, ultrasonic welding, adhesive, or the like (in the illustrated example, the heat seal 56). You may fix with the adhesive of a part sheet peripheral part. It is also possible to take a form in which the adhesive part is arranged outside the inner bag, without providing the adhesive part sheet, as a double structure having the inner bag and the outer bag as the entire packaging bag 1. In this case, the strength of the packaging bag 1 can be increased. The material of the adhesive sheet 55 is not particularly limited and can be selected from paper, resin sheet, etc., but if the packaging bag is made of a resin film, use a resin film capable of heat sealing and ultrasonic welding. Is preferred. The raw material of the resin film may be the same material as the packaging bag or a different material.

  In the adhesive portion 53, known adhesives such as a hot melt adhesive, an acrylic adhesive, a natural rubber adhesive, a synthetic rubber adhesive, and a silicone adhesive are arranged in layers, thin films, and meshes. .

  In FIG. 4, sectional drawing of the packaging bag 1 of the folded state is shown. When the peeling portion 52 is peeled off, the adhesive portion 53 is exposed outside the side surface of the intermediate portion M. When the side surface portion is folded according to the mountain fold auxiliary lines 21 and 22, the adhesive portion 53 faces the outer side surface of the bottom upper portion BH. When the adhesive portion 53 is attached to the corresponding portion of the bottom upper portion BH, the folded state is maintained. If the guideline is printed at a position suitable for adhering the adhesive part 53 on the outer side surface of the bottom upper BH, the adhesive part 53 is prevented from adhering to the wrong place, and the form of the packaging bag 1 is prevented from collapsing. Can do.

(Second Embodiment)
6 and 7 show a second embodiment. In 2nd Embodiment, the peeling part is distribute | arranged to the side surface outer side of bottom upper part BH. FIG. 7 shows a sectional view of the packaging bag 1 in a folded state. By peeling off the peeling portion 52, the adhesive portion 53 is exposed outside the side surface of the bottom upper portion BH. The adhesive portion 53 faces the outer side surface of the intermediate portion M when the side surface portion is folded according to the mountain fold auxiliary lines 21 and 22. When the adhesive portion 53 is attached to the corresponding portion of the intermediate portion M, the folded state is maintained.

(Third embodiment)
FIG. 8 shows a third embodiment. A plurality of the mountain fold auxiliary lines 21, the valley fold auxiliary lines 22, and the peeling portions 52 can be provided. FIG. 8 illustrates two forms of each. The packaging bag 1 having a relatively large capacity can be preferably used.

(Fourth embodiment)
FIG. 9 shows a fourth embodiment. Even in the packaging bag 3 having the drawstring structure around the take-out port, it is possible to make the bag compact while maintaining the drawstring structure by folding the side surface portion. As shown in FIG. 9, in this embodiment, there is an upper end TH formed by extending the side surface portion above the upper surface portion, and a string passage hole 91 is formed in an annular shape at the periphery of the upper end portion TH. Has been. The string passage hole 91 has at least one string passage opening 93 (two in the illustrated example), and a ring-shaped string 92 passed through the string passage hole 91 is exposed from the string passage opening 93 so that the user can By pinching the exposed portion of the string 92 and pulling it horizontally outward from the center of the horizontal cross section of the packaging bag 1 (in the direction of the arrow in the figure), the periphery of the upper end portion TH provided with the string through hole is narrowed. The position of the string passing hole is not limited to the upper end portion TH, and may be the peripheral edge 11 of the upper surface portion and the side surface top portion T. Further, the shape of the string-through hole may not be annular, and it is only necessary to be arranged around at least the upper end portion or the side surface top portion of the two opposing surfaces, or the two opposing sides of the upper end portion. The material of the string 92 is not particularly limited, and fiber yarns such as cotton, hemp, and polyester, and resin films such as polyethylene and polypropylene having an elongated structure can be used. The packaging bag 3 having a drawstring structure can be used more suitably because the contents are not popped out by overturning and excellent in portability when the upper end portion is narrowed. In the form in which one string and one string passage opening are arranged and the string is pulled only in one direction and the upper portion of the storage bag is closed, two strings and two string passage openings are arranged, and the two strings are opposite to each other. Both of the forms in which the upper part of the storage bag is squeezed by being pulled by the can be used.

  The present invention is suitable for a sanitary napkin packaging bag as in the above example, but can also be applied to packaging bags such as panty liners, disposable diapers, and absorbent pads.
