It was confirmed that is more preferable.

<Embodiment 2>
In the second embodiment of the present invention, unlike the first embodiment, the packaging bag accommodates the sanitary article 2 such that a gap L2 is formed when the article (the sanitary article 2 in the present embodiment) is accommodated. A restricting part is provided to restrict the space. The restricting portion is formed by, for example, heat sealing. By restricting the accommodation space of the sanitary product 2, the gap L2 is forcibly formed in the packaging bag, and the gripping allowance 20 is easily formed on the top surface portion 5 of the packaging bag. It becomes easier to open the bag. Two forms of the packaging bag provided with the regulation part will be described in the following Embodiment 2-1 and Embodiment 2-2, respectively. Among the elements constituting the packaging bags according to Embodiment 2-1 and Embodiment 2-2 shown in FIGS. 4 to 8, those having the same functions are denoted by the same reference numerals as those in Embodiment 1. The description is omitted.

<Embodiment 2-1>
Embodiment 2-1 of this invention demonstrates the example which provides the said control part in two places among packaging bags.

  4 and 5 show the packaging bag 1 and the packaging body 110 in which a gap is formed by the restricting portion 30 according to Embodiment 2-1 of the present invention. FIG. 4 is a perspective view, and FIG. 5 is a front view.

  In the packaging bag 1 which concerns on this embodiment, the control part 30 which controls the accommodation space of the sanitary goods 2 is provided so that when the sanitary goods 2 are accommodated, the gap | interval L2 is formed. Specifically, as shown in FIG. 5, the restricting portion 30 is formed by bonding two inner surfaces of two facing side portions of the packaging bag 1. As shown in FIG. 4, since the opposing side portions of the packaging bag 1 are bonded in the vicinity of the top portion 4, the stored sanitary product 2 can no longer go to the upper portion of the packaging bag 1, and the gap L2 is held.

  In the present embodiment, when the sanitary product 2 is inserted from the opened bottom portion of the packaging bag 1, the range of the accommodation place is determined by the restriction portion 30, and the gap L2 is forcibly formed in the packaging bag. According to the present embodiment, the grip allowance 20 is more easily formed on the top surface portion 5 of the packaging bag 1 than in the first embodiment, and as a result, the packaging bag 1 can be opened easily and quickly.

  In the present embodiment, it is preferable to provide the restricting portion 30 in the shape of a letter C as shown in FIGS. This is because the heat seal is not easily peeled off by the force (for example, insertion force or restoring force) generated by the sanitary product 2 when the sanitary product 2 is inserted from the bottom surface.

  An example of the shape of the control part provided in FIG. 6 at the packaging bag 1 and the package 110 which concerns on Embodiment 2-1 of this invention is shown. In the present embodiment, the restricting portion 30 has a letter C shape, but is not limited to this, and if the effect that the heat seal is not easily peeled off is obtained, an inverse L as shown in FIG. Two restricting portions 30 ′ having a letter shape may be used.

<Embodiment 2-2>
Embodiment 2-2 of this invention demonstrates the example which provides a control part in the four corner vicinity of a packaging bag.

  FIGS. 7 and 8 show the packaging bag 1 and the packaging body 111 in which a gap is formed by the restricting portion 31, according to Embodiment 2-2 of the present invention. FIG. 7 is a perspective view, and FIG. FIG. 8B is a sectional view taken along the line VIIIB-VIIIB in FIG.

  In the packaging bag 1 according to the present embodiment, as in the case of the embodiment 2-1, a regulation portion 31 that regulates the accommodation space of the sanitary product 2 is provided so that the gap L2 is formed when the sanitary product 2 is accommodated. It is done. Specifically, as shown in FIG. 8 (b), the restricting portion 31 is formed by bonding the inner surfaces of the four side portions near the four corners of the packaging bag 1. As shown in FIG. 8B, it can be seen that the vicinity of the four corners of the packaging bag 1 is adhered, and the cross-sectional area of the packaging bag 1 is smaller than the area of the top surface portion 5 of the packaging bag 1. Therefore, as shown in FIG. 8 (a), the stored sanitary article 2 does not go to the upper part of the packaging bag 1 any more, and the gap L2 is maintained.

  In the present embodiment, as in the case of the embodiment 2-1, when the sanitary product 2 is inserted from the opened bottom surface portion of the packaging bag 1, the range of the accommodation place is determined by the regulation unit 31, and the packaging bag is forcibly forced. A gap L2 is formed inside. Therefore, it is possible to obtain the same effect as that of the embodiment 2-1.
