Description

TECHNICAL FIELD The present invention relates to an absorbent article packaging bag having a grip portion.

A packaging bag with a gusset (also called a gusset) is conventionally known as a packaging bag for absorbent articles.

Light incontinence pads generally use a simple gusset-shaped packaging bag. In general, light incontinence pads are small in product size and relatively small in pack size, so they have been made in a simple shape without a handle or the like.

Recently, however, the number of large-capacity packs has increased, and along with this, pack sizes have increased. Such a large-sized pack is difficult to carry because of its simple rectangular parallelepiped shape without a handle. For this reason, handles are often attached to large pack size products such as adult diapers and baby diapers.

As an invention related to the manufacturing process of a conventional type of gusseted packaging bag, for example, Patent Document 1 discloses a conveying means 3 for conveying a strip-shaped tubular body 2 made of thermoplastic resin in the longitudinal direction and positioning it at a predetermined position. fusing means 4 for fusing the tubular body in the width direction at a predetermined length from the tip opening 2a of the tubular body 2; A cutting means 5 for cutting the cylindrical body in the width direction at a slightly rear portion, and a separating portion 20 disposed between the fusing means 4 and the cutting means 5 and having fusing end A and cutting end B as both ends. and a separating means 6 for separating the bag making apparatus.
Further, as an invention relating to a packaging bag with a handle, Patent Document 2 discloses a substantially hexahedral shape having a peripheral surface consisting of front and rear surfaces 3, 4 and both side surfaces 2, and upper and lower surfaces 5, 6. Disclosed is a packaging bag 1 in which a size confirmation part 10 showing a suitable size range of a wearing part of a sexual article in actual size is provided so as to be separable from the surrounding part by a perforation 11, and a handle. A form in which a handle hole 9 for passing a hand in the front-rear direction is formed in the center part in the left-right direction in the upper end part 7 formed by sealing the upper and lower edges as a sheet-like plastic film. The fold line 5c is folded inward to form a gusset, and both side portions are sealed to form a gusseted bag of the top folding type. Also disclosed is a configuration in which both end portions of the handbag loops 30, 30 are attached to the front and rear rib portions 32, 32 by suitable joining means such as fusion bonding.

However, although the packaging bag with hand holes as described in Patent Document 2 is easy to manufacture, the area of the handle portion is too large for a small package, so large diapers are purchased. There was a drawback that it was easy for others to notice that it was there.

In addition, the packaging bag with a handbag loop attached as described in the same Patent Document 2 requires attachment of a handle formed of a material different from that of the packaging film to the packaging bag after gusset packaging. It had the drawback of being difficult.

The present invention has been made in view of such circumstances, and even if the material, contents, manufacturing process, etc. are the same as those of conventional packaging bags, and the size of the handle is large, the area of the handle can be reduced. To provide a packaging bag for absorbent articles which is small and inconspicuous and can be held by a woman with one hand.

The inventor conducted extensive studies and found that a gusset-type packaging bag for absorbent articles is formed with a fold-structure gripping portion extending around the front surface, left and right side surfaces, and rear surface in a direction substantially parallel to the bottom surface. As a result, the materials, contents, manufacturing process, etc. are not different from conventional packaging bags, and even with large-sized packaging bags, the area of the handle is small and inconspicuous, so that women can hold it with one hand. A packaging bag for absorbent articles that can be manufactured can be obtained, and the present invention has been completed. That is, the present invention provides the following.

<Packaging process>
The absorbent article packaging bag 1 in this embodiment is a gusset type packaging bag (gusset packaging).
Gusset packaging is a method in which the inner surfaces of the packaging material are overlapped at both ends in the width direction so as to wrap the object placed on or under the sheet-like packaging material in a cylindrical shape. The combined parts are heat-sealed to form a cylindrical or square tube shape, and the bottom part or the mouth part is folded inward according to the length (height) of the bag to form a gusset. It is a packaging form in which each bag is made and sealed with a heat seal (top heat seal 20) or the like in a horizontal line, and each bag is cut at the sealed portion. This gusset packaging can be performed using known equipment.
The packaging bag 1 for absorbent articles in this embodiment includes the material of the packaging base material 2 to be used, the method (direction, etc.) and amount of the absorbent article to be inserted, the material and thickness of the heat-sealed portion after filling, and the finished packaging. Regarding the size of the bag, there is no change from the packaging form of the conventional packaging bag. Therefore, the packing process can be used with the conventional equipment.

In the packaging process described above, the process of forming the fold structure of the gripping portion 10 in the packaging base material 2 is performed as follows.
At the stage of sending the sheet-like packaging material 2 in FIG. 3 to the packaging process, there are front feeding rollers 21 and rear feeding rollers 22 for feeding the packaging material 2, as shown in FIG. 3(a). At this time, as shown in FIG. 3(b), if the front feed roller 21 is temporarily stopped and the rear feed roller 22 continues to operate, a difference in feeding speed of the packaging base material 2 occurs in the front-rear direction. As shown in FIG. 3(c), a grip portion 10 having a fold structure is formed. After that, it may be sent to the packaging process of the gusset packaging described above.
At the same time, it is preferable to provide the joint portion 12 described above so that the folded structure created at this time is not unraveled.
