You can see how they are doing. When the packaging bag 1 is closed, the packaging bag 1 is in the state shown in FIG.

  In the present embodiment, as shown in FIG. 4, the opening / closing part 8 extends in a direction substantially parallel to the arrangement direction of the sanitary goods 2 in the closed state of the packaging bag 1. That is, in the closed state, the opening / closing part 8 extends in a direction substantially parallel to the direction of action of the restoring force of the sanitary product 2 that is generated by being compressed and accommodated in the packaging bag 1. In other words, the direction in which the female engaging member 8 a and the male engaging member 8 b are engaged is a direction substantially perpendicular to the arrangement direction of the sanitary goods 2.

  FIG. 5 is a diagram for explaining the direction of action of the restoring force of the sanitary product that is generated by being compressed and accommodated in a packaging bag. 5A is a cross-sectional view in the VA-VA direction of FIG. 2A, and shows a state where sanitary goods are compressed and aligned in the packaging bag 1. FIG. 5B shows one sanitary article before being compressed and stored, and FIG. 5C shows one sanitary article after being compressed and stored.

As shown in FIG. 5 (a), the sanitary goods 2 ₁ , 2 ₂ , 2 ₃ , 2 ₄ to 2 _n-1 , 2 _n (n is an integer of 2 or more) are respectively compressed in the packaging bag 1. Contained. FIG 5 (b) and as shown in FIG. 5 (c), for example, on a sheet of sanitary articles 2 ₁ after accommodated by compression, one sanitary article prior to receiving by compressing 2 _'1 It can be seen that the restoring force F ₁ is generated so as to repel the compressed force. The remaining sanitary products 2 ₂ , 2 ₃ , 2 ₄ to 2 _n−1 , 2 _n are also compressed in the same manner as the sanitary products 2 ₁ , so that a restoring force similar to the restoring force F ₁ is generated respectively. . Then, the restoring force F ₂ generated from the plurality of sanitary products 2 ₁ , 2 ₂ , 2 ₃ , 2 ₄ to 2 _n−1 , 2 _n bulges the two opposing side surfaces A and A ′ to the outside. Thus, it works in a direction substantially perpendicular to the side surface portions A and A ′ (see FIG. 5A). Further, when the two opposing side surface portions A and A ′ bulge outward, forces are transmitted to the side surface portions B and B ′ integrated with the side surface portions A and A ′, respectively, and FIG. ), A force F ₃ recessed inwardly acts on the side surface portions B and B ′.

In FIG. 6, the cross-sectional shape C of the trunk | drum 3 of the packaging bag 1 before accommodating the several sanitary goods 2 is represented with a dashed-dotted line, and the trunk | drum 3 of the packaging bag 1 after the several sanitary goods 2 were accommodated. The cross sectional shape D is represented by a solid line. As shown in FIG. 6, the cross-sectional shape D is deformed by the restoring force F ₂ and the force F _{3 of} the plurality of sanitary articles 2 accommodated as compared to the cross-sectional shape C (in FIG. 6, the cross-sectional shape D is horizontally long). I understand).

Conventionally, the opposing side surface portions A and A ′ bulge outward due to the restoring force F _{2 of} the plurality of sanitary products 2 accommodated, so that the leading edge of the top portion 4 integrated with them is also outward. Due to the spreading force, it was difficult to close the opening of the packaging bag by the opening / closing portion, or the opening of the packaging bag was opened later even after closing.

In the present embodiment, in the closed state of the packaging bag 1, the opening / closing portion 8 is provided on the top portion 4 of the packaging bag 1 so that the opening / closing portion 8 extends substantially parallel to the direction of action of the restoring force F ₂ . With this configuration, interference acting direction of the restoring force F ₂ is comprised in the acting direction substantially perpendicular force to engage the pair of engagement members constituting the switching unit 8, the force restoring force F ₂ to the engagement Since this is suppressed, the closed state of the packaging bag 1 is maintained. Further, as shown in FIGS. 5A and 6, the two side portions B and B ′ facing each other by the force F ₃ are recessed inward, so that the tip edge of the top portion 4 integrated with them is also the same. Recessed inside. And since the action direction of the indenting force coincides with the action direction of the engaging force in the pair of engaging members constituting the opening / closing part 8, the engaging force of the opening / closing part 8 increases, and the packaging bag 1 The opening becomes difficult to open. Therefore, the closed state of the packaging bag 1 is maintained, and as a result, the clean state of the stored sanitary article 2 can be maintained.

In the present embodiment, sanitary goods are targeted as articles, but sanitary goods are more demanding to prevent foreign objects from entering the inside of the packaging bag than other articles. You can enjoy it. Further, among the sanitary goods, the pants-type diaper has a sufficient thickness. Therefore, the restoring force F ₂ is applied to the two side surface portions A and A ′ facing each other of the trunk portion of the packaging bag containing a plurality of diapers. Work hard. Therefore, when this embodiment is applied to a package containing a plurality of such pant-type diapers, the effect of maintaining the closed state of the packaging bag can be further improved as compared to a package containing other types of sanitary goods.
