Vinyl Waterproof Case (VINYL WATERPROOF CASE)

The present invention relates to a vinyl waterproof case, and more particularly, to a vinyl waterproof case that accommodates a mobile phone terminal, a notebook, a bill, various cards, etc. to act as a waterproof in the water.

In general, a vinyl waterproof case is used to store a portable object when swimming in a pool or stream.

This conventional vinyl waterproof case is provided with a sealing means 9 on the upper end of the vinyl case 3, as shown in FIG. The plastic case 3 is divided into a base paper 7 and a cover paper 5, and a mobile phone terminal is accommodated between the base paper 7 and the cover paper 5. The sealing means 9 comprises a second body 17 on which an upper end of the base paper 7 is fixed, and a first body 11 on which an upper end of the cover paper 5 is fixed. The first body 11 has a pair of lockers 15 which are rotated by the lever 13, and the second body 17 has a locking groove 19 in which the lockers 15 are inserted and locked. do.

By the above configuration, a mobile phone terminal is placed between the base paper 7 and the cover paper 5, the locker 15 is inserted into the fastening groove 19, and the lever 13 is turned to rotate the first body 11. And the second body 17 is locked while being in close contact. The sealing means 9 prevents water from penetrating into the plastic case 3.

However, the conventional vinyl waterproof case has to be molded by the sealing means 9, the increase in cost is a problem.

In order to solve this problem, the applicant has proposed a plastic case that serves as a waterproof device as a simple device as of 1998 Utility Model Application No. 12014 on July 1, 1998.

The present invention overcomes the above-mentioned conventional problems, and further improves the original invention, and an object of the present invention is to provide a waterproof waterproof vinyl sealable as a plastic case itself without a sealing means that is an injection molded product as in the prior art. It is.

As an example of a vinyl waterproof case for achieving the object of the present invention,

A cover sheet having a first sealing portion, and a second sealing portion formed at a predetermined distance from the first sealing portion,

On the inner surface in contact with the back surface of the cover paper is formed a pocket for accommodating a variety of small articles, a first sealing portion is formed above the pocket portion, the base paper is formed with a second sealing portion at a predetermined distance from the first sealing portion Wow,

An upper surface elongated above the second seal,

It extends to both sides of the plastic case and consists of an extension strap provided with a hook.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The vinyl case 32 is composed of a cover sheet 52 and a base sheet 50 having the same length as the cover sheet 52.

The first sealing part 44 is formed on the back surface of the cover paper 52, and the second sealing part 46 is formed at a predetermined distance from the first sealing part 44.

The inner surface of the base paper 50 in contact with the back surface of the cover paper 52 is formed with a pocket portion 38 for receiving various small items, the first sealing portion 44 is formed above the pocket portion 38 The second sealing part 46 is formed at predetermined intervals from the first sealing part 44. The outer edges of the base paper 50 and the cover paper 52 are heat sealed. In addition, the both sides of the base paper 50 and the cover paper 52, the hole 40 is formed between the heat-sealed portion 54 so that the string can be tied.

Both sides of the plastic case 32, the connecting straps 70, 72 are extended, one connecting strap 70 is provided with a female hook 42, the other connecting strap 72 is provided with a male hook 48 do.

Referring to FIG. 3, the first sealing part 44 and the second sealing part 46 have the same shape, and the locking base 60 is formed in the base paper 50, and the locking groove 60 is formed. On both sides, a plurality of sub-projections 62 are formed. The cover paper 52 includes a main protrusion 56 snap-fit into the locking groove 60, and a sub protrusion 57 protruding from both sides of the main protrusion 56. The sub protrusions 57 and 62 are mutually positioned so as to cross each other.

An upper surface 53 having a long length is formed at an upper side of the second sealing part 46.

The vinyl waterproof case according to the present invention by the configuration as described above operates as follows.

A mobile phone is inserted between the backing paper 50 and the cover paper 52, and a telephone card or the like is placed in the pocket portion 38, and the first sealing portion 44 and the second sealing portion 46 are pressed from both sides. The main protrusion 56 of the cover paper 52 is snapped into the locking groove 60 of the base paper 50, and both sub-protrusions 57 and 62 are in close contact with each other.

In this state, when folded from the upper end of the upper surface 53 at a predetermined interval, the state becomes as shown in FIG. 5, and in this state, the male hooks 48 are folded to the female hooks 42 by folding the connecting strings 70 and 72. The male hook 48 is fastened to the female hook 42 by being folded at the folding portion (A).

Then, even if the plastic case 32 is submerged in water, the percolation of the water is first detached from the upper surface 53 folded several times, and secondly, the sub-projections 57 and 62 of the second seal 46 are blocked. 3, it is completely blocked by the main projection 56 and the locking groove (60). It is also quaternarily blocked at sub-projections 57 and 62 on the opposite side.

If there is water passing through the second seal 46, it is interspersed in the folded portion between the first seal 44 and, if water is passed through the folded seal, again by the first seal 44 Waterproof in the same manner as the second seal 46.

As described above, the vinyl waterproof case according to the present invention can be manufactured at low cost because the sealing means is added to the plastic case by heat fusion without the need for preparing an injection mold. There is no effect that it becomes convenient to use.

What has been described above is just one embodiment for carrying out the vinyl waterproof case according to the present invention, the present invention is not limited to the above embodiment, the subject matter of the present invention claimed in the following utility model registration claims Any person having ordinary knowledge in the field to which the present invention pertains may make various changes without departing from the scope of the present invention.
