[0002]

2. Description of the Related Art Conventional examples I Japanese Patent Application Laid-Open Nos. 7-291370 and 8-19835.
In the conventional example I described in Japanese Patent Publication No. 0, a storage bag is made from an airtight sheet made of a flexible resin, and several tens of wet sheets are placed inside the storage bag. A shape-shaped outlet is formed, and the outlet is configured to be hermetically sealed by a stickable and releasable open / close label coated with a pressure-sensitive adhesive or the like. However, in the conventional example I, since the resin sheet constituting the storage bag is flexible, the periphery of the outlet is soft, and the force for keeping the shape constant is weak. For this reason, when trying to take out the wet sheets one by one, the take-out opening may be deformed in accordance with the passage of the wet sheets, and a number of wet sheets may slip out.
In particular, this phenomenon occurs in that the wet sheet is zigzag-folded and one end edge of the other wet sheet is alternately inserted into the middle of one wet sheet to form an aggregate, and one of the superposed upper sheets is picked up When,
It is remarkable that the wet sheet on the lower surface can be lifted up following it. Further, even if the opening / closing label is affixed in a state where the periphery of the outlet is deformed or wrinkled, since the sealing property is lost, the inconvenience that the internal wet sheet dries easily occurs.

Conventional Example II Conventional Example II described in JP-A-7-215379
In this example, a storage bag made of a resin sheet similar to that of the conventional example I is placed in a paper-made storage box having a certain degree of rigidity, and a plastic opening / closing lid unit is attached to the storage box. The opening / closing lid unit has a main body having an opening formed substantially in the center,
A lid is connected to the main body via a hinge, and the lid can seal the opening. When the storage bag is put in the storage box, the opening of the opening / closing lid unit is located right above the outlet of the storage bag. Therefore, when the lid of the opening / closing lid unit of the storage box is opened, the wet sheet can be taken out from the outlet of the storage bag below. However, in the conventional example II, since the outlet of the storage bag is formed of a soft resin sheet, it is easily deformed, so that no resistance can be applied to the wet sheet being taken out. Therefore, the wet sheets cannot be taken out one by one as in the conventional example I. In addition, various methods have been adopted for attaching the plastic opening / closing lid unit to the paper box or the like. For example, a step formed on the upper surface of the paper box and the lower surface of the main body of the opening / closing lid unit is used. There is a method in which a hole having a shape that fits properly is formed, a step portion is positioned and inserted into the hole, and then bonded. However, such a manufacturing method that requires drilling and accurate positioning has a problem that it takes time and effort and productivity is poor. For example, the limit is about 50 pieces per minute.

Conventional example III Conventional example III described in JP-A-8-318977 is
A plastic opening / closing lid unit is directly attached to a storage bag made of a soft resin sheet. Although the details of the opening / closing lid unit are different, the basic structure is the same as that of the conventional example II. However, this conventional example has a problem that manufacturing is difficult and productivity is poor. That is, a rib is provided around the opening in the body of the opening / closing lid unit, and a flat outer edge is provided around the opening.On the other hand, a hole is formed in the upper surface of the storage bag, and the body is placed inside the storage bag. Only the ribs and the lid around the opening are exposed outward from the hole, and the flat outer edge of the opening / closing lid unit is adhered to the back surface around the hole of the storage bag. As described above, it is very difficult to temporarily insert the member (opening / closing lid unit) to be exposed into the inside of the storage bag, and the rib is accurately positioned in the hole. Because it is difficult to use a machine, it cannot be manufactured fully automatically, and manual work is indispensable in part.

Conventional example IV Conventional example IV described in JP-A-8-337276.
Is a case where a plastic opening / closing lid unit is attached to a firm storage box made of paper. The method of mounting the opening / closing lid unit also involves forming a hole in the upper surface of the storage box, putting the opening / closing lid unit in the storage box, and bonding the front side of the main body of the opening / closing lid unit to the back surface of the storage box. Conventional example II
It has the same disadvantages as I, but with poor productivity.
