Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a box with an inner bag (bag-in carton) for a packaging container that can store foodstuffs, etc. in a sealed state.

[Prior art] Conventionally, for example, Utility Model Publication No. 55-30235 and Publication No. 55-44774
Techniques such as those shown in the above publications have also been developed.

[Problem that the invention attempts to solve]

These conventional techniques all involve gluing the back surface of the outer box and the surface of the inner bag stored therein, so if the tear zipper on the outer box and the inner bag peel off, the objective cannot be achieved, so both have to be bonded together. Strong adhesion is required, and if it is strongly adhered, there is a risk that the film that makes up the inner bag will separate between layers, so the strength of the envelope seal for the inner bag is weaker than the adhesive strength between the outer box and the inner bag. On the other hand, if the sealing strength of the inner bag is made too weak, the sealing becomes incomplete and there are problems such as loss of airtightness.

[Means for solving problems]

This invention was devised by paying attention to such conventional problems, and the present invention will be explained with reference to the drawings as follows.

That is, in FIGS. 1 to 6, A is an outer box in which a side plate 1, a front plate 2, a side plate 3, a rear plate 4, and an adhesive piece 5 are successively arranged, and these side plates 1,3
Lid plates 6 and 7 are connected to the upper and lower ends of the front and rear plates 2 and 4, respectively, and a strip-shaped tear zipper 8 is formed along the entire upper part of the outer box by cutting lines. The zipper 8 is located at the boundary between 1 and the front plate 2.
An opening piece 9 is provided that serves as the starting point of the cut. As shown in FIG. 3, adhesive 10 is applied to the back side of the outer box A at predetermined positions, but the points to pay particular attention to are the parts of the zipper 8 corresponding to the side plates 1 and the parts of the zipper 8 that correspond to the side plates 1.
Adhesives 10a and 10b are applied to a part of the surface corresponding to the adhesive plate 5, respectively, and the other parts of the zipper 8 are not applied with adhesive 10 at all.

Next, B is an inner bag made of a film oriented in the width direction to which the envelope seal is pasted, part 1.
The side end becomes a protruding piece 11 which protrudes outward, and a part thereof has an opening piece 12 formed of upper and lower notches at a position corresponding to the zipper 8.

Regarding the structure of the container according to the present invention, etc., please refer to Section 5.
As shown in the figures and FIG. Inner bag B is attached to outer box A so that they are stuck together and held together.
It can be stored inside to form a whole.

[Effect]

Since the box according to the present invention has the above-described structure, when taking out the product stored in the inner bag B, as shown in FIG. 3. Tear off the zipper 8 of the part corresponding to the back plate 4 one after another, and finally remove the side plate 1 and the adhesive piece 5
At the same time, the projecting pieces 1 stuck and held by these zippers 8 are torn apart.
1 opening piece 12, and then this zipper 8
By pulling the opening piece 12 connected to the opening piece 1, the inner bag B is pulled into the opening piece 1 while utilizing the directionality of the film.
The inner bag B can be opened by tearing the width of 2 and the stored product can be taken out.

[Effect of idea]

In the present invention, as mentioned above, since the opening piece of the inner bag is stuck to the zipper on the front and back surfaces, the opening piece and the part following it can be delaminated by tearing the zipper. It is possible to tear the inner bag without any problems, and it can be opened even if the seal part of the inner bag is strengthened, so the seal can be maintained, and the inner bag can be opened after tearing the zipper of the outer box. , the inner bag can be opened after confirming its sealing status, giving consumers a sense of security, and can be opened smoothly without requiring much force, and since the zipper is connected to the inner bag, it will not scatter. It has the following characteristics.

[Brief explanation of the drawing]

1 and 5 are assembled sectional views, FIGS. 2 to 4 are component parts views, and FIG. 6 is a sectional view in use. A is an outer box, B is an inner bag, 1 and 3 are side plates, 2 and 4 are front and rear plates, 5 is an adhesive piece, 8 is a zipper, and 9 and 12 are opening pieces.

Claims (1)

[Scope of utility model registration request] An outer box A consisting of a side plate 1, a front plate 2, a side plate 3, a rear plate 4, an adhesive piece 5, lid plates 6, 7, etc., and a film with directionality are used, and the side edges thereof are made to protrude to form a protruding piece. 11, a tear zipper 8 is bored in the outer box A, and the cut opening piece is provided at the side end of the front plate 2, and an opening is made in the protruding piece 11 of the inner bag B. A box with an inner bag formed by forming a piece 12 and holding the front and back surfaces of the opening piece 12 between the side plate 1 of the outer box A and the adhesive piece 5.
