The present invention relates to a packaging bag for storing absorbent articles such as sanitary napkins, and more particularly to a packaging bag for absorbent articles that can be used as a bag for disposing of used absorbent articles in bulk.

BACKGROUND ART Conventionally, absorbent articles such as sanitary napkins and disposable diapers have been folded into small pieces and packaged individually, and a plurality of absorbent articles have been sold together in a single packaging bag.

Such a packaging bag is disclosed in Patent Document 1 below, which includes a body and a top that covers the top of the body, and the top has an opening part for opening the packaging bag, and has a breakable part. an opening part including a plurality of opening lines for opening the packaging bag by forming an opening according to the opening, and a pair of engaging parts disposed across the opening part and capable of selectively covering the opening by engagement. A packaging bag is disclosed that has a joint part and is provided with an opening/closing part that can open/close the inside of the packaging bag.

Further, in Patent Document 2 listed below, an opening through which the absorbent articles are taken in and taken out is formed in a bag that accommodates a plurality of absorbent articles, and the bag is releasably attached to the surface of the bag around the opening. , a package is disclosed that is equipped with a lid that opens and closes an opening.

JP2017-24742A Japanese Patent Application Publication No. 2014-101140

As in Patent Documents 1 and 2 above, in conventional packaging bags, the opening for taking out the stored absorbent article can be easily opened/closed, or the opening for taking out the stored absorbent article can be easily taken out. However, there has been no prior art that allows the packaging bag to be used as a disposal bag for used absorbent articles.

When using a packaging bag as a bag for disposing of used absorbent articles, conventionally, after storing the used absorbent articles in the packaging bag, when closing the opening of the bag, the opening of the bag is narrowly gathered. Commonly used methods include tying it once, and pinching the periphery of the opening in two places and tying them together. However, the former method requires a fairly long bag portion from the opening to tie the knot, and has the disadvantage that it cannot accommodate a large amount of used absorbent articles. In addition, the latter method has the drawback that it is difficult to close the opening without any gaps, and the used absorbent article inside is visible through the gaps in the openings.

On the other hand, in order to dispose of the used absorbent article, the user must separately prepare a plastic bag for disposal, and it is a hassle to bring such a plastic bag into the toilet. In addition, from the perspective of reducing environmental impact, the number of plastic bags used when purchasing products has decreased, and people are now more likely to bring their own bags.In addition, the hassle and financial burden of having to purchase plastic bags for disposal has become more common. was there.

Furthermore, when a used absorbent article is disposed of in a transparent or translucent plastic bag, there is a problem in that the inside is visible. On the other hand, when a packaging bag for absorbent articles is used as a disposal bag for used absorbent articles, since the packaging bag is printed, the used absorbent articles contained therein are removed from the outside. Although it has the advantage of being difficult to see, it has the above-mentioned disadvantages because there is no means to close the opening for taking in and taking out absorbent articles, so it has rarely been used as a disposal bag. By the way, the packaging bag described in Patent Document 1 is equipped with a so-called zipper that can close the opening, but when the bag is filled with used absorbent articles, the zipper does not close the opening. There was a risk that it would not be possible.

Therefore, the main object of the present invention is to make it possible to use a packaging bag for absorbent articles as a bag for disposing of used absorbent articles, to eliminate the hassle of carrying a plastic bag to the toilet, and to ensure that the opening can be closed. An object of the present invention is to provide a packaging bag for absorbent articles.

In order to solve the above problems, in a first aspect, a plurality of absorbent articles are housed and formed into a rectangular parallelepiped shape having a top part, a bottom part, a front part, a back part and a pair of side parts. A packaging bag for absorbent articles,
Gusset portions folded into a triangular shape are formed on both sides of the upper surface portion, and gusset portions are formed in portions of the upper surface portion excluding the gusset portions, and extend in diagonal directions from connecting sides with the front portion and the back portion, respectively. An easily breakable part is formed that can form a tying piece,
The easy-to-break portion includes a pair of first easy-to-break portions each extending along the gusset portion and each having a substantially V-shape in plan view, and a second easy-to-break portion connecting the tops of the first easy-to-break portions on both sides. A pair of third third parts extend from the top of one of the first easily breakable parts toward the connecting side with the front part, and extend from the top of the other first easily breakable part towards the connecting side with the back part. It consists of an easy-to-break part,
The binding piece portion formed by the portion surrounded by the first easy-to-break part, the second easy-to-break part, and the third easy-to-break part has a connecting side with the front side and a connecting side with the back side. One piece each extends from

Embodiments of the present invention will be described in detail below with reference to the drawings.

[First form example]
As shown in FIG. 1, the packaging bag 1 according to the first embodiment of the present invention stores a plurality of sanitary napkins N, and has a top part 2, a bottom part 3, a front part 4, a back part 5, and a pair of sanitary napkins N. It is formed into a rectangular parallelepiped shape having side parts 6, 6. The term "rectangular parallelepiped" is a concept that is not limited to a rectangular parallelepiped in which the connecting sides of adjacent surfaces are formed by clear straight lines, but also includes a rectangular parallelepiped that can be regarded as the same as a rectangular parallelepiped as a whole. For example, it includes cases where each side where each surface connects to each other and each vertex are slightly rounded.

In this specification, unless otherwise specified, the "vertical direction" is the direction that connects the top surface part 2 and the bottom surface part 3, and the "front-back direction" is the direction that connects the front surface part 4 and the back surface part 5. The "left-right direction" is the direction that connects the side surfaces 6, 6 to each other.

The packaging bag 1 is preferably manufactured from a flexible thin sheet material. The material constituting the packaging bag 1 can be resin, non-woven fabric, paper, etc., and is not limited, but resin films (polyethylene film, polypropylene film, etc.) are particularly preferably used. When a resin film is used, it is usually colored to be opaque so that the contents of the packaging bag 1 are not visible from the outside, and the product name and other necessary information are printed on the outer surface.

Sealing portions 7 are formed on the top surface 2 and bottom surface 3 of the packaging bag 1, respectively, to seal the openings at both ends of the packaging bag material made of a tubular resin film. The sealing portion 7 is formed at the center portion of the top surface portion 2 and the bottom surface portion 3 in the front-rear direction, over the entire length in the left-right direction. As a bonding means for the sealing portion 7, known means such as heat sealing, ultrasonic sealing, adhesive, etc. can be used.

Triangularly folded gusset portions 8, 8 are formed on both sides (both ends in the left-right direction) of the top surface portion 2 and the bottom surface portion 3, respectively. The portion of the gusset portion 8 extending from the side surface portion 6 is folded back in a substantially right-angled isosceles triangular shape, and the outside thereof is covered by portions extending from the front portion 4 and the back portion 5. The gusset portion 8 formed in the shape of a substantially right-angled isosceles triangle has a base corresponding to a connection side with the side surface portion 6, and an apex angle directed toward the center of the top surface portion 2 or the bottom surface portion 3. Thereby, the sealing part 7 is disposed at a position passing through the center of the base and the apex of the apex of the gusset part 8 formed in the shape of a substantially right-angled isosceles triangle.

FIG. 1 discloses a configuration in which a plurality of sanitary napkins N folded into a flat rectangular shape and individually packaged are stored vertically between both side parts 6, 6 so that the planes are perpendicular to the left-right direction. However, the storage form of the sanitary napkin N is not particularly limited. For example, a plurality of them may be stored vertically between the front part 4 and the back part 5 so that the planes are perpendicular to the front-rear direction, or between the top part 2 and the bottom part 3 so that the planes are perpendicular to the vertical direction. They may be stored by stacking them horizontally. In addition, when storing vertically, two or more layers may be stacked in the vertical direction.

As shown in FIGS. 1 and 2, the portion of the upper surface portion 2 excluding the gusset portion 8 is provided with binding pieces 10 extending diagonally from the connection sides with the front portion 4 and the back portion 5, respectively. An easily breakable portion 9 is formed that can form a breakable portion 9. As a result, the packaging bag 1 according to the present invention can store a plurality of used sanitary napkins by tying the tying pieces 10, 10 together with the used sanitary napkins stored in the packaging bag 1. It is now possible to dispose of sanitary napkins all at once.

The easy-to-break part 9 may be any known part, such as a perforation or a notch, as long as it allows the packaging bag 1 to be easily broken, but perforations are particularly preferred.

By breaking the top surface 2 of the packaging bag 1 at the easy-to-break part 9, the tying piece 10 is formed as described above, and the binding piece 10 is stored in the packaging bag 1 as shown in FIG. An opening serving as an outlet for removing the sanitary napkin N is now formed.

As described above, the opening of the packaging bag 1 can be easily closed by tying the tying pieces 10, 10 together, so the packaging bag 1 can be used as a bag for disposing of used sanitary napkins. This makes it possible to save the trouble of carrying a separate plastic bag for disposal to the toilet, and also to reduce the cost of purchasing such plastic bags. In addition, the binding piece 10 is formed on the upper surface 2 excluding the gusset portion 8 so as to extend diagonally from the connection sides with the front portion 4 and the back portion 5, respectively. A sufficient length for tying the tying pieces 10, 10 together can be secured, and the opening of the packaging bag 1 can be easily and reliably closed. Furthermore, since the tying piece 10 is formed on a portion of the upper surface 2 excluding the gusset portion 8, the gusset portion 8 can be placed so as to cover and hide the used sanitary napkin, and then the tying By tying the binding pieces 10, 10 together, it is possible to prevent the used sanitary napkin inside from being seen through the gap between the knots.

To explain the easy-to-break part 9 in more detail, in the packaging bag 1 according to the first embodiment, the easy-to-break part 9 extends along the gusset parts 8, 8, as shown in FIGS. 1 and 2. a pair of first easy-to-break parts 9A each extending in a substantially V-shape in plan view; a second easy-to-break part 9B connecting the tops of the first easy-to-break parts 9A, 9A on both sides; A pair of third easily breakable parts extend from the top of the first easily breakable part 9A toward the connection side with the front part 4, and extend from the top of the first easily breakable part 9A on the left side in FIG. It is composed of an easily breakable portion 9C.

In the packaging bag 1 according to the first embodiment, the tying piece 10 is formed by a portion surrounded by the first easy-to-break part 9A, the second easy-to-break part 9B, and the third easy-to-break part 9C. One piece of this binding piece 10 extends from the connecting side with the front part 4 and the connecting side with the back part 5, respectively.

The first breakable portion 9A is formed in a substantially V-shape along two inclined sides of each gusset portion 8 folded into a triangular shape. The first breakable portion 9A is formed on the outer line of the gusset portion 8 or at a position that is slightly spaced apart from the outer line and does not overlap with the gusset portion 8. Both ends of the first breakable portion 9A formed in a substantially V shape are located at or near the corner between the front portion 4 and the side portion 6 and at or near the corner between the back portion 5 and the side portion 6. , the top portion is located on or near the sealing portion 7.

The second easily breakable portion 9B is formed linearly along the sealing portion 7 so as to connect the tops of the first easily breakable portions 9A, 9A on both sides. By breaking the first easy-to-break part 9A and the second easy-to-break part 9B, as shown in FIG. become.

The third easy-to-break portions 9C extend from the tops of the first easy-to-break portions 9A toward the connection sides with the front part 4 or the connection sides with the back part 5, respectively. By breaking at this third easily breakable portion 9C, the binding piece 10 is formed. The third easy-to-break portion 9C may be broken when the packaging bag 1 is opened to form an outlet for taking out the sanitary napkin N stored therein, or when the used sanitary napkin N is removed from the packaging bag 1. You can also do this when closing the opening of the bag after filling it.

As shown in FIG. 2, the third easily breakable portion 9C is connected to the connecting side with the front portion 4 or the back portion 5, as shown in FIG. It is preferable to set the length L1 along the connecting side to a position where it is equal to or shorter than the length L2 of the second easily breakable portion 9B. L1 is the length between the first easy-to-break part 9A and the second easy-to-break part 9B along the connection side with the front part 4 or the back part 5 of the binding piece part 10. By setting the length L1 to be equal to or less than L2, it is possible to prevent the width of the base end of the tying piece 10 from becoming larger than the width of the tip, making it difficult to tie the tying pieces 10, 10 together. can.

To explain more specifically, the position where the third easily breakable part 9C connects with the connecting side with the front part 4 or the back part 5 is the vertex of one first easily breakable part 9A, as shown in FIG. The intersection point P when a perpendicular line H is drawn from O to the connecting side with the front part 4 or the back part 5 and the extension line J of the oblique side of the other first easily breakable part 9A are the front part 4 or the back part 5. It is preferable to arrange it between the intersection point Q that intersects the connection side of . However, as shown in FIG. 4, when the length of the upper surface part 2 in the left-right direction is A and the length in the front-rear direction is B, the shape of the upper surface part 2 is A>1.5B, and the upper surface The condition is that the perpendicular line H of the portion 2 and the extension line J do not intersect. When the connection position of the third easily breakable part 9C with the connection side with the front part 4 or the back part 5 is outside the intersection PQ between the intersections PQ, the proximal end of the tying piece 10 If the width of the base end of the tying piece 10 is too small and there is a risk of it breaking when pulled strongly when tying, and if it is outside the intersection Q between the intersections PQ, the width of the proximal end of the tying piece 10 may be This makes it difficult to tie the tying pieces 10, 10 together.

The tying piece part 10 extending from the connecting side with the front part 4 and the tying piece part 10 extending from the connecting side with the back part 5 are symmetrical in the front-back direction along the second easily breakable part 9B. , and are formed in substantially the same shape and are arranged symmetrically in the left-right direction along the perpendicular line at the center of the second easily breakable portion 9B. By symmetrically arranging the pieces having the same shape, when tying the tying pieces 10, 10 together, approximately equal force acts on the front, back, left and right sides, making it easier to tie.

To open the packaging bag 1 according to the first embodiment, as shown in FIG. 3, the upper surface part 2 is broken at the first easy-to-break part 9A and the second easy-to-break part 9B. This forms an opening that serves as an outlet for the sanitary napkin N stored in the packaging bag 1.

Next, a method for disposing of used sanitary napkins all together using the packaging bag 1 will be explained. First of all, after taking out all the sanitary napkins N stored inside from the packaging bag 1 in the opened state shown in FIG. form 10. This empty packaging bag 1 is used as a disposal bag for used sanitary napkins. When the packaging bag 1 is full of used sanitary napkins, as shown in FIG. The tying pieces 10, 10 are tied together with the used sanitary napkin covered. In this way, the used sanitary napkin is covered and hidden by the top surface 2 of the packaging bag 1 including the gusset part 8, making it difficult to see the used sanitary napkin inside and allowing it to be disposed of as is. Become.

[ Reference second form example]
As shown in FIGS. 6 and 7, in the packaging bag 1 according to the second reference embodiment, the easily breakable part 9 has a pair of substantially V-shaped parts extending along the gusset parts 8 and 8 in a plan view. A first easy-to-break part 9A, a second easy-to-break part 9B that connects the tops of the first easy-to-break parts 9A and 9A on both sides, and a second easy-to-break part 9B that extends orthogonally to the center of the second easy-to-break part 9B, and extends from the front side. A third easy-to-break part 9C that extends to the middle part that does not reach the connection side with the front part 4 and the back part 5, and a connection side with the front part 4 or the back part 5, respectively, starting from the end of the third easy-to-break part 9C. It is comprised of a pair of fourth easily breakable parts 9D, 9D extending in a substantially V-shape in plan view.

In the packaging bag 1 according to the second reference embodiment, the binding is performed by the portion surrounded by the first easy-to-break part 9A, the second easy-to-break part 9B, the third easy-to-break part 9C, and the fourth easy-to-break part 9D. Two binding pieces 10 are formed, and two pieces each extend from the connection side with the front part 4 and the connection side with the back part 5.

As shown in FIG. 7, the length L3 of the third easily broken portion 9C in the second reference embodiment is the length of the connecting side of the top surface portion 2 with the side surface portion 6 (in the front-rear direction of the top surface portion 2). It is preferably less than half of the length B) (L3≦0.5B), preferably 0≦L3≦0.5B. If the length L3 is greater than 0.5B, the width of the tip of the tying piece 10 becomes too large, making it difficult to tie the tying pieces 10 together.

As shown in FIG. 7, the position where the fourth easily breakable part 9D in the second reference embodiment connects with the connection side with the front part 4 or the back part 5 is from the vertex O of each first easily breakable part 9A. Preferably, it is an intersection point P when a perpendicular line H is drawn to the connection side with the front part 4 or the back part 5. As a result, when tying the tying pieces 10, 10 together, the tying piece 10 does not tear even if it is pulled strongly, and has sufficient strength. Easier to tie.

In order to open the packaging bag 1 according to the second reference embodiment, as shown in FIG. The upper surface portion 2 is broken at a portion 9D. As a result, an opening serving as an outlet for the sanitary napkin N stored in the packaging bag 1 is formed, and at the same time, four tying pieces 10, 10, . . . are formed. In this way, in the packaging bag 1 according to the second embodiment, the tying pieces 10, 10, . . . are formed at the stage when the opening for taking out the sanitary napkin N is formed. It becomes possible to save the effort of separately performing cutting to form the portion 10.

Next, a method for collectively disposing of used sanitary napkins using the packaging bag 1 according to the second reference embodiment will be described. After taking out the sanitary napkin N and putting the used sanitary napkin into the empty packaging bag 1, when it is full, remove the upper surface part 2 other than the tying pieces 10, 10, . . . including the gusset part 8 (see FIG. The tying pieces 10, 10 are tied together while the used sanitary napkin is covered with the used sanitary napkin (other than the hatched area in 7). At this time, it is preferable to tie the two binding pieces 10, 10 facing each other diagonally on the upper surface part 2, but the two adjacent binding pieces 10, 10 are tied together. You may. In the packaging bag 1 according to the second reference embodiment, two knots are formed by tying the two tying pieces 10, 10 together, so that the opening of the packaging bag 1 can be more reliably closed. .

[Other form examples]
In the above embodiment, both ends of the first easily breakable portion 9A start from the corner between the front part 4 and the side part 6 in the top part 2, or the corner part between the back part 5 and the side part 6 in the top part 2, respectively. Although it extends diagonally, it may extend to the front part 4 or the back part 5, as shown in FIG. 9, or it may extend to the side part 6, although not shown. In this way, by extending the first easily breakable part 9A to the front part 4, the back part 5, and the side part 6, when the packaging bag 1 is opened and the opened part is folded back to form an opening, the inside can be opened. Since the upper end of the sanitary napkin N stored in the sanitary napkin N protrudes from the opening, the sanitary napkin N can be easily taken out without getting caught on the edge of the opening. Furthermore, the gusset portion 8 is difficult to be separated when the packaging bag 1 is opened.
