Description

[Detailed Description of the Invention] The present invention relates to an integrated package in which 2 to 10 self-supporting bags are integrated and packaged.

The self-supporting bag shown in FIG. 3 is increasingly being used as a beverage container instead of a can because of its low disposal and packaging costs.

However, although these self-supporting bags are flexible, they are easily deformed, so when they were to be displayed, they were removed from packaging boxes such as cardboard boxes and displayed one by one.

Furthermore, since self-supporting bags are flexible, it is difficult to transport and stock them in a stacked state.

When self-supporting bags were to be packaged together, it was common to fit them into a frame with cuts as shown in Figure 1, or to arrange them on a molded plastic tray and shrink-wrap them.

However, such a packaging method requires a high packaging cost, and there has been a desire for an integrated package that can be packaged at low cost and that can be stacked.

In view of the above points of the present invention, the packaging cost is low and the integrated packaging body can package 2 to 10 self-supporting bags.

The present invention will be described in detail below with reference to the drawings.

As shown in Fig. 2, the frame used in the package of the present invention consists of side walls 1 and 2 having inwardly curved sides, a top plate 3, and a bottom plate 4, each of which is bent along a fold line between them, and one end is glued. This is the frame body 5 made of.

Further, in the fold line portions at the four corners of the frame 5, parallel cuts 7, 7 are provided across the fold lines, and fold lines are provided at the edges of the cuts 7, 7, and a locking portion 8 is formed by bending inward.
It is a frame with a

The self-supporting bag A shown in FIG. 3 is inserted into the opening of the frame body 5 shown in FIG. 2 from both directions as shown in FIG. This is an integrated package of bags.

By providing a locking portion here, the bottom of the self-supporting bag inserted into the bag is locked, and the bag can be stored more reliably.

Moreover, the width of the top plate 3 and bottom plate 4 of the frame body 5 is
It is smaller than the total thickness of the bottom of the self-supporting bag shown in the figure, and the side wall 2 is curved inward, so when shrink-wrapping with shrink film, the shrink film is constrained to the shape of the frame. The middle part of the self-supporting bag can be tightened more than the top plate and bottom plate parts, and the effect of integrated packaging due to shrinkage can be fully exhibited.

Furthermore, if the shape of the side wall of the frame is rectangular, even if the width of the side wall is smaller than the total thickness of the bottom of the self-supporting bag, the shrinkable film will be constrained to the shape of the frame when shrink-wrapped with shrinkable film. Therefore, the middle part of the self-supporting bag cannot be tightened more than the other parts, and the effect of integrated packaging due to shrinkage cannot be fully exhibited, and the self-supporting bag moves within the frame, which is undesirable.

In this way, the present invention uses a small frame and a shrink film to avoid deforming the corners of the self-supporting bag, and also
- It is an integrated package that can be stacked in groups of 10, and can be stacked without using cardboard boxes etc.
It is now possible to exhibit.

Furthermore, since it is simply wrapped in shrink film, it can be seen through from the outside, further enhancing the display effect.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A top plate and a bottom plate each having a side wall that curves inward and whose side wall width is smaller than the total thickness of the bottom of the self-supporting bag after filling, are folded along the respective fold lines. An integrated package of self-supporting bags, which is formed by inserting two or more self-supporting bags into a bent frame from both sides of the frame and covering the periphery with a shrinkable film. (2) The utility model registration claim described in paragraph 1, wherein the frame is provided with a locking part formed by bending inward parallel cuts that extend from the side wall to the top plate and from the side wall to the bottom plate. An integrated package of self-supporting bags.
