[Problems to be solved by the device]

 However, in the case of the waterproof pouch constructed by any of the above-mentioned bags, since the opening / closing opening is formed by the sheet members made of synthetic resin overlapping, the edge formed with the opening / closing opening is different. Even if the parts are folded into a winding shape and fastened with the surface-attaching tape, the pulling force applied to the sheet member when the object is stored in the bag, the restoring force of the sheet member, and the loop forming the surface-attaching tape. Due to the synergistic effect with the elastic deformation of the hook, the folded part is loosened and the complete airtightness is not secured. The first problem is that there is a second problem in that when the winding folds are multiple in order to improve the airtightness, the material usage fee increases and the cost increases. there were.

As a fastening means by a pair of surface-mounting pieces using surface-mounting tape, one of the surface-mounting pieces is attached by welding the periphery to the back side of the bag body, and the other of the surface-mounting piece is the bag body. If the structure is such that the periphery is welded and attached to the inner surface of the fastening tongue whose one edge is welded and fixed so that the opening side is the free edge on the front side of the Although it does not affect, it is necessary to manufacture an extra fastening tongue and weld it to the bag body, so it is possible to simplify the structure including improving the airtightness. This is the third issue.

The purpose is to provide a waterproof pouch that can improve manufacturability.

[0006]

[Means for Solving the Problems]

 The present invention includes means for solving the above-mentioned first problem, two means for solving the second problem, and means for solving the third problem. The problem-solving means is the whole or main part of the invention.

The first means for solving the problem is to use an opening / closing port (2) for loading and unloading an article at one end of a bag body (1) formed of a conventional synthetic resin sheet, and to front the bag body (1). Based on the structure of the waterproof pouch provided with a pair of fastening means that can be detachably fastened to the side and the back side in a state where the edge portion where the opening / closing port (2) is formed is folded in a winding shape, On the inner surface of the edge of one sheet member and the inner surface of the edge of the other sheet member forming the opening / closing port (2), there are engaging protrusions (3) and engaging grooves (4) that engage with each other. It is to provide a sealing means.

[0008] One of the second means for solving problems is to form a fold for folding the edge portion where the opening / closing opening (2) is formed into a winding shape in addition to the means for solving the first problem. That is.

Another one of the second problem-solving means is the above-mentioned first problem-solving means and / or the second problem-solving means, and a pair of fastening means having a width equal to or less than the width of the bag body (1). One side of the surface-attachment piece (5) formed by the length or the surface-attachment tape divided in the range of the length is attached by welding the periphery to the back side of the bag body (1). The other side of () is welded to the front side of the bag (1) by welding the periphery to the inner surface of the fastening tongue (6) which is fixed by welding so that one end of the bag is a free edge on the opening (2) side. It is a configuration that is attached or uses a plurality of pairs of snaps consisting of welded male and female.

A third problem solving means is, in addition to the first problem solving means, a surface formed by a surface-adhesive tape having a length equal to or less than the width of the bag body (1) or divided in the range of the length. This means that the periphery of the piece (5) was directly welded to the front side and the back side.

[0011]

[Effect of the invention]

 The waterproof pouches manufactured according to the first, second and third means for solving the problems according to the present invention are the inner surface of the edge of one of the sheet members forming the opening / closing port (2) and the other sheet member. Since the inner surface of the edge of the bag is equipped with a sealing step consisting of the engaging projections (3) and the engaging grooves (4) that engage with each other, it is possible to store items in the bag (1). Even if the folded portion is loosened due to the synergistic effect of the tensile force applied to the sheet member, the restoring force of the sheet member, and the elastic deformation of the hook and the loop forming the surface-attachment tape, the engagement protrusion (3) Engagement with the engaging groove (4) secures the sealing property of the opening (2) and maintains high airtightness, preventing water from entering from the opening / closing port (2), and if necessary. It is also possible to seal the air by means of this, so that failure of the stored items due to flooding or slipping during removal can occur. Is prevented, it is possible to reduce the collision damage with other products by the buffer action of sealed air.

In particular, in the third means for solving the problem described in claim 3, the fastening means using a pair of surface-mounting tapes is divided into a length equal to or less than the width of the bag body (1) or a range of the length. Since the peripheral edges of the pair of surface-attachment pieces (5) formed by the surface-attachment tape are directly welded to the front side and the back side, one of the surface-attachment tapes is welded to the fastening tongue piece (6). Compared with the structure, the production of the fastening tongue (6) and the welding work of the fastening tongue (6) to the bag body (1) are unnecessary, and the waterproof effect and the cushioning effect due to the improvement of the airtightness are impaired. In addition, the work cost and material cost can be reduced, and in the case of being wound and fastened, each face piece (5) is hidden without being exposed to the outside to improve the appearance. Not only can the surface of the fastening portion be used as a free decorative portion.
