Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a container consisting of an inner bag and an outer box that can store food, etc. This invention relates to a packaging container that can be opened.

<Conventional technology> Conventionally, a container has an inner bag stored in an outer box,
As a simultaneous opening type container configured so that an inner bag and an outer box can be opened at the same time, the technology shown in Japanese Utility Model Application Publication No. 52-87429 or No. 57-63075 is known.

In the former case, two parallel perforation lines are provided on the outer box to form a strip-shaped peeling part, and two perforation lines are perforated on the adhesive part of the inner bag to form a joint, and the inner bag is removed. This is a technique in which the joint part of the inner bag is adhered to the peeling part of the outer box via an adhesive when the product is stored in the outer box.

In the latter case, two parallel cut lines are provided on the outer box to form a strip-shaped peeling section, and a cut tape is pasted along the entire inner circumference of the inner bag, and a cut tape is attached to the side edge of the inner bag along the cut tape. This is a technique in which a notch is made in the cut tape, and the protruding end of the cut tape is joined to the outer box.

<Problem to be solved by the invention> However, among the above-mentioned technologies, the former involves punching two tear lines in the inner bag to provide a joining part, and joining this joining part to the peeling part of the outer box. So,
When storing the inner bag in the outer box, both have to be attached to each other, resulting in a problem that the overall structure is complicated and the work of assembling the structure is difficult.

In addition, for the latter, cut tape must be attached to the entire inner surface of the inner bag, a notch must be made along the cut tape on the side edge of the inner bag, and the protruding tip of the cut tape must be joined to the outer box. As a result, there were problems such as the overall complexity, poor workability, and difficulty in mass production.

The container according to the present invention relates to a completely new technology developed in view of these conventional problems.

In particular, when storing the inner bag in the outer box, this technology eliminates the need to attach the two to each other at all.

<Means for solving the problem> The present invention is a completely new technology that fundamentally improves the conventional problems mentioned above. In the container, a tear zipper for tearing and opening is provided by making two parallel cut lines in the outer box, and a window is bored on the extension line of the tear zipper close to one end of the tear zipper. A pair of notches are formed in the side edges of the inner bag to form an opening piece for tearing and opening, and the inner bag is opened so that the opening piece of the inner bag is exposed through the window of the outer box. It is constructed by storing a bag inside an outer box.

<Function> As described above, in the present invention, a window is provided in the outer box near the tear zipper, and the opening piece provided in the side edge seal portion of the inner bag is exposed through this window. With this structure, when holding the opening piece and tearing the inner bag, the tear zipper of the outer box can be torn off at the same time to open the bag.

In the present invention, as described above, it is sufficient to store the inner bag in the outer box so that the opening piece is exposed through the window, so there is no need to join the two together as in the prior art.

Furthermore, when tearing the inner bag along the tear zipper of the outer box, the wall surface of the inner bag following the opening piece of the inner bag is guided by the two cutting edges of the tear zipper, so that the direction Even an inner bag made of a neutral film can be cut smoothly and accurately in the transverse direction with a constant width.

<Example> An embodiment of the container according to the present invention will be specifically explained with reference to figures. Figure 1 is an explanatory diagram of the outer box of the container according to the present invention, and Figure 2 is an illustration of the inner bag of the container according to the present invention. FIGS. 3 and 4 are explanatory views showing the state of the assembled configuration of the container, and FIGS. 5 and 6 are explanatory views showing the sealing type of the inner bag, respectively.

First, in FIG. 1, reference numeral 1 is the paper outer box of the container of the present application, and the upper part has two parallel cut lines so that a tear zipper 2 for tearing and opening can easily tear it. It is perforated. Further, a window 3 is bored on the extension line of the tear zipper 2 close to one end of the tear zipper 2.

Next, in FIG. 2, reference numeral 4 denotes an inner bag housed within the outer box 1, which is made of a film such as plastic film or aluminum foil. The upper opening of the inner bag 4 is sealed, and a tear opening is formed on the side edge of the inner bag 4 by a pair of upper and lower notches 5 at positions corresponding to the windows 3 of the outer box 1. A piece 6 is provided.

Further, in assembling the container according to the present invention, as shown in FIGS. 3 and 4, the inner bag 4 is stored as is in the outer box 1, and the opening piece 6 of the inner bag 4 is is exposed through the window 3 of the outer box 1, the opening piece 6 is pinched from the outside of the outer box 5, and the lid plate of the outer box 1 is attached to close the opening of the outer box. The whole can be assembled and configured.

As shown in FIGS. 5A and 5B, the opening piece 6 of the inner bag 4 explained in the above embodiment is provided with a pair of notches 5 on the side edge continuous with the seal part 7 stuck in a gusset shape. Therefore, it can also be configured or
As shown in Figures A and B, it is also possible to provide a pair of cut notches 5 on the side edges continuous with the seal part 8 pasted in an envelope-like manner.

<Effects of the Invention> As described above, the container according to the present invention is extremely simple to assemble since there is no need to attach the inner bag stored in the outer box to the outer box.

Since a window is bored in the outer box and an opening piece is provided in the inner bag, by aligning the two, the opening piece can be automatically exposed through the window of the outer box and assembled. I can do it.

This window was provided on the extension line of one end of the tear zipper of the outer box and close to it, so by holding the opening piece and pulling it along the tear zipper, it would be connected to the opening piece of the inner bag together with the tear zipper. The container can be opened all at once by tearing off the walls at the same time.

In addition, when the wall following the opening piece of the inner bag is torn, it is cut while being guided by the cutting edges on both the upper and lower sides of the tear zipper, so even if the inner bag is made of non-directional film, it can be cut with a certain width. It has features such as being able to be opened smoothly and accurately in the horizontal direction.
