DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for easily closing an opening so as to prevent the stored product or the like from jumping out when the content such as the product is stored and displayed at a store or brought back. It is related to a plastic bag made.

[0002]

2. Description of the Related Art Conventionally, as a plastic bag of this kind, Japanese Utility Model Registration No. 3058837 has been proposed. 5 (a), a self-adhesion portion 53, to which a release film 52 is temporarily attached, is provided in an opening portion 51 of a bag 50, as shown in FIG. 5 (b). After the storage, the release film 52 is peeled off to expose the self-adhesion portion 53 and the opening portion 51 is abutted to be easily bound.

[0003]

However, in the bag 50 proposed above, the handle hole 55 provided in the opening 51 is below the self-attaching portion 53. Therefore, when the opening 51 is bound, the inside of the bag is closed. When the contents 54 sealed and contained therein contained moisture, there was no escape space for moisture or the space was extremely narrow, and the moisture was trapped in the bag, and mold and the like were easily generated.

In the case where the bag 50 is made of a transparent plastic base material so that the contents can be seen from the outside during display, if the opening 51 is bound by the self-adhesion portion 53, the bag will be exposed to the moisture. There was also a problem that the wood was immediately clouded. In order to solve this problem, it has been considered to use an anti-fog film as a transparent plastic substrate or to use a film in which the anti-fog film is adhered to the inner surface, but remove moisture trapped in the bag. It wasn't a good solution because we couldn't do it.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems at once, and a plastic bag capable of efficiently releasing moisture out of the bag while enabling the opening of the bag to be more easily bound. It is intended to provide.

[0006]

In order to achieve the above-mentioned object, the present invention provides a plastic bag provided with a chuck having a re-opening / closing function in an opening, wherein a hand-held hole is provided below the chuck. It is characterized in that it is provided so that even when the opening is bound, the handle hole can be used as a moisture outlet as it is.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below with reference to FIGS.
Description will be made based on the embodiment shown in FIG. This application bag 10
The bag 10 is provided with a chuck 12 having a re-opening / closing function at the opening 11 of the bag 10. A handle hole 13 is provided below the chuck 12. Therefore, even when the opening 12 is closed by engaging the chuck 12, as shown in FIG.
Function as an outlet for the moisture S emanating from the air (it becomes a circulation hole for outside air).

As shown in FIG. 3, the chuck 12 is capable of engaging with the concave streak 1 using the elasticity of a plastic material.
2a and a tape 12b 'having a ridge 12b. The tape 12a' and 12b 'are used to adhere to the facing surface of the opening 11 of the bag 10 of the present application through high frequency bonding or adhesive bonding. Glued by means. In addition, it goes without saying that the bag 10 of the present application may be obtained by using a plastic film provided with the above-mentioned concave streaks or convex streaks in advance.

In the case of the bag 10 of the present application, in the case of the form shown in FIG. 1, the openings 11 are abutted in the form of a palm, and the concave streak 12a and the convex streak 12b are partially overlapped with each other. Is strongly pressed from the outside of the opening 11 with the thumb and the index finger, the concave streaks 12a and the convex streaks 12b bite each other at the pinched portion, so that the pinching position is sequentially moved in the muscle direction or pinched. By squeezing in the muscle direction in the state, the opening 11 can be easily sealed over the entire area.

When the opening 11 is released, the opening 11 is grasped with both fingers and a slightly strong force is applied in the direction of releasing the occlusion. A part of the added occlusion is released, and thereafter the entire area can be easily opened with a small force.

When the bag 10 of the present application is of a type in which one of the openings 11 is extended from the other as shown in FIG. Thus, a concave streak 12a and a convex streak 12b are provided on the respective surfaces facing each other. Also in this case, as shown in FIG. 4B, the handle hole 13 provided below the binding position naturally functions as an outlet for the moisture S emanating from the contents 14.

A handle hole 1 provided below the chuck 12
3 has an elliptical shape in the example of the figure, but may be a rectangle having a circular arc at the corner or the like. FIG. 4 (a)
As described above, the upper edge 13a and the lower edge 13b of the handle hole 13 may be connected to each other by the band-shaped portion 13c so as to endure the weight of the contents. This case is advantageous in that a thin and inexpensive material can be used as the material of the bag 10 of the present application. Also, although not shown, assuming a bag for storing heavy contents in advance,
In some cases, a reinforcing tape or a reinforcing film may be attached to a portion where the hook hole 13 is formed or its periphery.

Next, the operation of the present bag 10 will be described. First, the opening 11 of the bag 10 of the present application is widely opened, and contents 14 such as products are stored. Next, the opening 12 is bound by engaging the chuck 12 with a predetermined method.

Thus, the bag 10 of the present application in which the contents 14 are stored and the opening 11 is bound is, for example, shiitake mushrooms or other products having a high moisture content because the handle holes 13 are open. However, since the moisture S escapes through the handle hole 13, the moisture is not trapped in the bag, and there is almost no fear of generating mold or the like.

Further, even if the bag 10 of the present application is made of a transparent plastic substrate, there is no danger that the substrate will become cloudy due to moisture during display of the product and the contents will not be visible from the outside. Therefore,
A better state can be maintained by using an anti-fog film or a plastic substrate having an anti-fog film adhered to the inner surface as the transparent plastic substrate.

Although the bag 10 of the present application has been described by taking a three-dimensional bag as an example, it goes without saying that the bag 10 may be a flat bag or another bag.

[0017]

As described above, the present invention relates to a plastic bag provided with a chuck having a re-opening / closing function at an opening, and characterized in that a handle hole is provided below the chuck. The product can be easily filled in a state where the chuck is opened, and after filling the product, the opening can be easily bound by biting by pressing with a finger, and the preparation work for displaying the product at the store is easy. Even if the bag falls during the display, there is no danger of the product or the like jumping out.

Furthermore, even after the opening is bound, the handle hole functions as a moisture discharge port, so that moisture is not trapped in the bag, and mold and the like are not generated in the contents. In addition, various excellent effects are exhibited, for example, the transparent substrate is not clouded by moisture.
