Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to an improvement in a water-proof case for storing and using water-resistant products of portable communication devices such as mobile phones.

[0002]

[Prior art]

 A conventional waterproof case of this type is a bag in which one or more seal fasteners are formed on the open / close portion of a synthetic resin bag, and is fastened with Velcro when the open / close portion is folded in a rolled shape. In addition, products configured to waterproof stored products are commercially available and known.

[0003]

[Problems to be solved by the invention]

 However, in the case of a bag in which one or more seal fasteners are formed at the opening / closing portion of the above-mentioned synthetic resin bag, the air inside the synthetic resin bag expands due to the external environment due to a high temperature state or the like. In addition, it was confirmed that the sealed portion of the seal fastener may be opened due to the expansion of the synthetic resin bag. The first point is that if the sealed part of the seal fastener is opened once, it will be open unless it is closed artificially, and water will enter from that part, causing inconvenience such as failure of stored items. There are issues.

[0004] Further, a bag in which one or a plurality of seal fasteners are formed at the opening / closing portion of the synthetic resin bag, and the opening / closing portion of the synthetic resin bag is folded into a bag and fastened with magic tape. In the case of a synthetic resin bag, the air inside the synthetic resin bag expands due to the external environment such as a high temperature condition, and at that time, the synthetic resin bag expands, thereby opening and closing the open / close portion of the synthetic resin bag. The second point is that there is a possibility that holes such as holes may be broken in the bonded part of the synthetic resin bag due to high sealing performance, and water may enter from that part, causing inconvenience such as breakdown of stored items. There are issues.

[0005]

[Means for Solving the Problems]

 The present invention includes a means for solving the first problem and a means for solving the second problem.

Means for solving the first problem are to form a seal fastener (3) on an upper end opening / closing portion (2) of a synthetic resin bag (1) capable of storing a mobile phone and to hinge at a central portion. Attach a plastic bag clip (4) in the shape of an iron perm refracting in step (8), and the plastic bag clip (4) has ridges slightly displaced from each other on the inner surface on one side and the inner surface on the other side. (5) By forming (6), a means for bending the synthetic resin bag body (1) below the upper end opening / closing part (2) to be in a sealed state when the two parts face each other is bent. It is to provide.

A means for solving the second problem is that air inside the synthetic resin bag (1) expands due to an external environment, and at that time, the synthetic resin bag (1) expands. Before the damage such as a hole in the bonded part (9) of the synthetic resin bag body (1), the inside air leaked slightly from the closed plastic bag clip (4). A means for forming ridges (5) and (6) slightly shifted from each other on the inner surface on one side and the inner surface on the other side of the plastic bag clip (4).

[0008] A hole (10) having a size to which a portable cord or strap (11) can be attached is formed on the upper part of the plastic bag clip (4).

[0009]

[Effect of the invention]

 The waterproof case manufactured according to the first and second means for solving the problems according to the present invention is constructed such that the air inside the synthetic resin bag body (1) expands due to an external environment due to a high temperature state or the like. Before the expansion of the body (1) causes damage such as a hole in the bonded portion (9) of the synthetic resin bag body (1), the seal fastener (3) and the plastic bag clip (4) are damaged. The sealed part of) opens slightly, which will result in a small leak of air inside. At this point, it was confirmed that water would not easily enter the interior. However, if the internal pressure is reduced due to some internal air leakage, water can be infiltrated. However, the plastic bag clip (4) cannot be used because of the elasticity of the material of the plastic bag clip (4). This has the effect that the lower part of the synthetic resin bag body (1) below the open / closed portion can be sealed again.

As a result, the air inside the synthetic resin bag body (1) expands due to the external environment due to a high temperature state or the like, and at this time, the synthetic resin bag body (1) expands, thereby causing the synthetic resin bag body to expand. It is possible to provide a waterproof case capable of waterproofing the stored goods without causing any damage such as a hole in the bonded portion (9) of the body (1) and hardly allowing water to enter the inside.

In addition, by forming a hole (10) large enough to attach a portable cord or strap (11) on the upper part of the plastic bag clip (4), the cord (10) is inserted into the hole (10). It has the effect of making it easy to carry around by attaching a strap or strap.

【Example】

 A synthetic resin sheet (12) for the back surface having a length of 190 mm, width 75 mm and thickness of 0.3 mm and a front surface synthetic resin sheet (13) having a length of 180 mm, width 75 mm and thickness of 0.2 mm are provided at the longitudinal end and lower part. To form a synthetic resin bag (1) capable of storing a mobile phone having an opening and closing portion at the top. A seal fastener (3) having a length of 75 mm corresponding to the width of the synthetic resin bag (1) is formed 5 mm below the upper end opening / closing part (2). A plastic bag clip (4) in the shape of an iron perm with a size of 20 mm long, 90 mm wide and 10 mm thick when bent by the hinge (8) at the center. The plastic bag clip (4) is attached to the inner surface of one side and the inner surface of the other side by attaching an adhesive or a fixing pin (14) to the upper part of the back synthetic resin sheet (12) so as to enter the inside of the bag clip. The ridges (5) and (6), 1 mm long, 75 mm wide, and 6 mm high, slightly displaced from each other, were formed below the seal fastener so that they were bent and faced each other. At this time, the lower part of the synthetic resin bag (1) from the upper end opening / closing part (2) is sandwiched so as to be in a sealed state.

[0013] A hole (10) having a diameter of 5 mm is formed on the upper part of the plastic bag clip (4) to which a portable cord or strap (11) can be attached.

It goes without saying that the present invention is not limited to such an example.
