DISCLOSURE OF THE INVENTION

The problem which the present invention is intended to solve is that the closing means must be operated to open the opening portion while preventing the dropping out of the housed article because the opening portion of the aforementioned housing bag is closed with the closing means with the result that there arises a disadvantage in that the user cannot swiftly take out the housed article. In addition, an attachment work for attaching the closing means onto the opening portion must be added to the manufacturing process.

An object of the present invention is to provide a housing bag which solves the aforementioned problem with the result that the housing bag, does not require any closing means, facilitate the handling by the user and the manufacture thereof while preventing the dropping out of the housed article and the widening of the opening portion.

In order to solve the aforementioned problem, the housing bag according to the present invention has an internal configuration which is approximately the same as an external configuration of an article to be housed therein, and a bag-like configuration having an opening at one side thereof; the bag being characterized by comprising:

a cushion material; and

an auxiliary material having an elasticity, a stability and an endurance higher than the cushion material and the material constituting the main portion of the bag;

wherein the cushion material and auxiliary material are arranged in an overlapping manner on the internal circumference of the opening portion along the internal circumference thereof with the result that the opening portion is formed in a thick manner with an elasticity.

Incidentally, preferably, the aforementioned auxiliary material is a thermo-plastic urethane resin-made sheet.

According to the present invention, it is possible to realize a housing bag wherein the opening portion is formed of a cushion material in a thick manner instead of providing the closing means for closing the opening portion, so that the housed article is pressed to the internal circumference of the opening portion to prevent an easy dropping out of the housed article and the taking out of the housed article is facilitated.

Furthermore, an auxiliary material with a high elasticity, stability and endurance is used together with the cushion material with the result that it is possible to prevent the widening of the opening portion and an easy dropping out of the housed article.

BEST MODE OF EMBODYING THE INVENTION

In FIG. 1(a), symbol A shows a housing bag according to the present invention. This housing bag A is intended to house and protect a portable game device and the housing bag A is constituted in such a manner that taking in and out of the housed article is facilitated, and easy dropping out of the housed portable game device is prevented and it is easily taken out.

A main body 1 of the bag which constitutes the housing bag A is provided with a surface processing with polyurethane in order to protect a cloth (Tetron cotton) from stains, moisture or the like, and the bag is formed in such a manner that the width W1 is approximately the same as the thickness W2 of the article to be housed and the depth L1 is made approximately the same as the height L2 of the housed article so that the internal configuration of the bag is made approximately the same as the external configuration of the article. The main body thereof is formed in an approximately rectangular bag-like configuration having an open one end. On an internal circumference of the opening portion 2, as shown in FIG. 1(b), a cushion material 3 is provided. The opening portion 2 is formed in a thick manner with the cushion material 3 to narrow the opening portion 2. The dropping out of the housed article is prevented without providing any closing means such as a string, a button, a fastener or the like while an auxiliary material 4 with a high elasticity, stability and endurance is arranged on an internal circumference of the cushion material 3. According to the present invention, urethane is used as the aforementioned cushion material 3, and a thermo-plastic urethane resin is used as the auxiliary material 4.

In this housing bag A, as shown in FIG. 2(a), a tape-like auxiliary material 4 is overlapped at both end portions in the longitudinal direction of the rear surface 5a of the cloth 5 constituting the main body 1 of the bag. After overlapping a belt-like cushion material 3 thereon, the surface 5b of both end portions is folded back to the side of the rear surface 5a respectively so as to wrap the cushion material 4 and the auxiliary material 3, and the cushion material 3 and the auxiliary material 4 are housed in the folded back portion 6 by stitching the cushion material 3 and the auxiliary material 4 together with the folded back portion 6 along the “a line” so that a thick portion 7 is formed. Thereafter, as shown in FIG. 2(c), the cloth 5 is folded at the center thereof so that the rear surface 5a is directed toward the outside so that the main body thereof is formed in a bag-like configuration by stitching both side portions and the lower portion of the cloth 5 along the “b line” and the “c line” respectively (see FIG. 2(d)). As shown in FIG. 2(e), when the cloth 5 is folded back, the folded back portion 6 is located at the inner side of the opening portion 2 with the result that the housing bag A can be formed which has an opening portion 2 provided with a thick portion 7.

Incidentally, when both end portions of the cloth 5 are stitched along the “b line”, it is preferable that the portions be stitched in the state in which the auxiliary material 4 is extended to some extent. As a consequence, when the auxiliary material 4 is restored after the stitching, the inner circumference of the opening portion 2 can be made somewhat smaller than the external circumference of the housed article.

The housing bag A which is formed as described above is such that the depth L1 is made approximately the same as the height L2 of the housed article B and the width W1 is made approximately the same as the thickness W2 of the housed article B with the result that the configuration of the inside is made approximately in the same configuration as the housed article. (see FIGS. 3(a) and (b).

In housing the article B to be housed in the aforementioned housing bag A, as shown in FIG. 3(a), the article B to be housed is pressed into the bag from the opening portion 2. At the time of actually pressing the article B to be housed into the opening portion 2, as shown in FIG. 3(b), the article B is pressed into the bag by pressing the thick portion 7 toward a right-wise and a left-wise direction. As shown in FIG. 3(c), in the state in which the article B to be housed is housed in the housing bag A, the depth L1 of the housing bag A is approximately the same as the height of the article B to be housed with the result that the upper portion of the article B to be housed corresponds to the thick portion 7 of the opening portion 2. Since the internal circumference surface of the opening portion 2 is made thick, the opening portion 2 is sandwiched by this thick portion 7 with the result that the article B to be housed is pressed by the thick portion 7 so that dropping out of the article B to be housed from the opening 2 is made difficult.

As shown in FIG. 4(a), when this article B to be housed is taken out of the housing bag A, as shown in FIG. 4(b), pressing the bottom of the housing bag A from below results in the pressing out of the housed article B from the opening portion 2 with the result that the projected portion of the article B is pinched and pulled out from the housing bag. Thus, the housed article can be easily taken out without the operation of opening of the opening portion such as unraveling of the string, detaching of the button, opening of the fastener or the like.

At the time of taking in or out of the housed article B, the opening portion 2 is forcibly widened with the result that there is a possibility that the closing state of the opening portion 2 is not maintained by reason that the cushion material 3 has gone slack by taking in and out of the housed article B repeatedly. However, the auxiliary material 4 which is soft like rubber and which is formed of strong thermo-plastic urethane resin such as plastics and metal maintains the state of the opening portion 2. Consequently, a housing bag A can be realized which is capable of maintaining the closed state of the opening 2 forever by recovering the expansion and slack of the cushion material 3 and which is capable of preventing the dropping out of the housed article B without using a closing means such as a button and a fastener for closing the opening portion while being capable of taking out the housed article B without operating the closing means, the bag being effective both for the manufacturer side and for the user side.
