Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention is a bag made of a synthetic resin film having a bottom gusset (hereinafter referred to as a "bag bag") or a can container on the bottom of a bag without a handle. The present invention relates to a bottom plate made of cardboard with a flange that allows the flat state of the bottom surface to be maintained even when it is housed.

(B) Conventional technology Although the handbag 10 made of a synthetic resin film handbag having a bottom gusset is made for a can container, when the can container is accommodated in a single bag, the entire circumference of the can container 10 is covered. The uprightness is maintained by touching the inside, and the handbag 10
The bottom surface of the container has a shape in which the tangent line of each can container formed by pressing each can container is continuous.

Also, a cardboard having the same shape as the bottom shape when the can container was stored was placed on the bottom of the carrying bag 10.

(C) Problems to be solved by the invention However, the bottom surface of the handbag 10 can maintain a flat and normal state when the can container is fully accommodated. Not only was the appearance distorted and unsightly, but the image of the product was also damaged.

Further, in a case where a cardboard having the same shape as the bottom shape when the can container is accommodated is placed on the bottom of the handbag 10, in the case where the capacity of the can container becomes small, not only the cardboard is deformed, but also the bottom and bottom plates are The normal state of was not able to be maintained.

The present invention stabilizes the flat state of the bottom of the handbag 10 with a bottom plate with a flange, and when the handbag 10 is folded, the bottom 1 of the bottom plate 1 and the flange portion 2 are folded so that the handbag 10 or a bag without a handle is folded. It is intended to provide a folding bottom plate of a bag which can be inserted into a bag and simultaneously polymerized and stacked.

(D) Means for Solving the Problems The present invention has the following configuration in order to achieve the above object.

That is, the bending line of the outer bending line 3 in the left and right direction of the center of the bottom face 1 made of cardboard of a size inscribed in the rectangular bottom of the spreading bag 10 and the inner bending lines 4 on both sides of the bottom face 1 of the carrying bag 10. Flange portions 2 that stand upright are provided on both side surfaces of the bottom, and an outer bending line 3 of the bottom surface 1 extends to the apex of the flange portion 2 (see FIG. 1).

(E) Action Since it is configured as described above, the outer bag 3 of the entire length of the bottom plate is folded (see FIG. 2), and the folded carrying bag 10
Place the top part of the lower gusset part so as to sandwich it (see FIG. 5).

When storing the can container, open the upper edge of the handbag 10 and push the bottom open, and the bottom plate will be flat on the outer bend line 3 and the inner bend line 4 will be bent to form the flange 2 on the side face of the handbag 10. The can container can be accommodated in such a manner that the flat bottom surface 1 is naturally formed so as to stand upright from the bottom surface 1 (see FIGS. 4 and 6) while being in contact with the can 1.

(E) Embodiment An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of the bottom plate, FIG. 2 is a perspective view in which the outer bending line 3 is bent, FIG. 3 is a perspective view in which the top and bottom of FIG. 2 are turned upside down, and FIG. 4 is an inner bending line. 4 is a perspective view in which only the bag 4 is bent, FIG. 5 is a front view in which the outer bending line 3 is folded and sandwiched at the bottom of the bag 10 and FIG. 6 is a state in which the bag 10 is opened so that the can container can be accommodated. It is a perspective view.

The carrying bag 10 is formed by folding an upper gusset portion of a film made of nylon, polyethylene or the like by bending the upper portion and a lower gusset portion by bending the lower portion so as to be in front of and behind the bag. The left and right ends up to the lower gusset portion are adhered with the left and right ends being overlapped to form a bag state, and a handle is attached to the handle, including a handle without a handle.

Reference numeral 1 denotes a bottom surface, which is a pole paper having an area similar to that of the inner bottom of the handbag 10, and a fold line of the outward bending line 3 is provided over the entire length in the left and right of the center.

In the 2 flange portion, equilateral triangles with both sides as one side are provided at both ends of the bottom surface 1 to provide folds of the inner bending line 4, and the folds of the outer bending line 3 of the bottom surface 1 are extended to the apex of the flange portion 2. Set up.

The regular triangular shape of the flange portion 2 is the same as the triangular shape that is formed on the upright side surface of the lower gusset that occurs when the handbag 10 is opened, but is not particularly limited, and is semicircular, semielliptical, square. The shape and other polygonal shapes may be used.

Further, in the description of the present invention, the bag made of synthetic resin film having the bottom gusset is used, but it may be a paper bag, a cloth bag, a leather bag, etc., and the bottom plate may be a metal plate or a wooden plate.

In use, the folded bag 10 is inserted so that the upper side of the lower gusset is sandwiched (see Fig. 5), so that multiple bags can be stacked and packed and transported. When storing cans, the bag 10 is opened. Open the side and push the outer bending line 3 until the bottom surface 1 becomes flat, while the upper opening of the handbag 10 becomes a quadrangle, while both ends of the lower gusset naturally form an equilateral triangle with the bottom as one side. Also, the inner bending lines 4 on both sides of the bottom surface 1 of the present invention are naturally bent, and the flange portion 2 stands upright to obtain an inscribed state (see FIG. 6).

Since the bottom plate of the present invention is laid on the bottom of the handbag 10 opened in a quadrangle, the bottom and the appearance of the handbag 10 are not significantly deformed even if the can container is partially or partially housed. You can carry it with you.

(G) Effect of the Invention In the present invention, the bottom can be held flat when the can container is housed in the handbag 10 as described above, but even if a small number of can containers are housed, the shape is not so much. It does not deform and can be carried around in a good appearance.

Further, even when the handbag 10 is folded, the bottom plate of the present invention can be folded in two by the outer bending line 3 and inserted so as to sandwich the lower gusset, so that it does not become bulky by stacking a number of sheets and the volume is not so large during transportation. It does not increase and does not hurt.

Furthermore, when the bag 10 is opened, the bottom of the bag 10 spreads out in a quadrangle by pushing the back of the outer bending line 3 of the bent bottom plate so that the bottom surface 1 becomes flat and the side surface of the bag 10 is outside the flange 2. Since the fold line 3 is naturally guided, the handbag 10 can be opened upright and brought into contact with the inner surface of the handbag 10 in one operation, so that the handbag 10 can be easily opened.
