[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container suitable for packaging confectionery cakes such as roll cakes. More specifically, it can be assembled from a single blank sheet, and can be stably stacked when in use.Especially, a large opening area can be obtained when storing and unloading contents, and the bottom and side surfaces become flat. It relates to a container having a bottom.

[0002]

2. Description of the Related Art Conventionally, confectionery cakes and the like are housed and sold in cartons attached to ordinary boxes. But,
This kind of cake box is difficult to obtain a large opening area for convenient storage and removal of the contents, and has insufficient stability when stacked, and thus an improvement in this point has been desired. In addition, the conventional box stores roll cake, pound cake, etc.,
It was not a good-looking packaging suitable for sale to consumers as it is.

By the way, a container having a large opening area at the time of storing and taking out the contents and having a flat bottom surface and side surfaces is known from Japanese Utility Model Publication No. 61-16984, for example.
In this apparatus, a two-foldable auxiliary bottom plate is connected to one side end of the bottom plate and can be folded on the inner surface of the side plate or can be linearly extended to the side of the bottom plate.

[0004] However, this conventional example also has a problem that when containers are stacked at the time of storage or display, the containers move in the left-right direction or the front-rear direction and are liable to collapse. Furthermore, this product has a drawback that it cannot be mechanically attached at the time of assembling and has a structure in which it is exclusively assembled by hand, resulting in poor mass productivity.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to assemble a single blank sheet by mechanical bonding with good mass productivity. When unpacking and storing or taking out the contents, the bottom and side surfaces should be flat to provide a large opening area, and at the time of storage, they can be stably stacked without moving left, right, front and back. An object of the present invention is to provide a package having a possible raised bottom and suitable for storing and selling confectionery such as a roll cake having a good appearance.

[0006]

In order to achieve the above object, a container according to the present invention has a narrow bottom wall, a side wall, and a lid plate sequentially connected symmetrically about a rectangular bottom plate. , side walls and respectively symmetrically end plate above and below the cover plate, thereby connecting the junction flap and closing plate, engraved a Gyakuorikei on the boundary of the bottom plate and the reinforcing wall, before the time of assembly
The reinforcing wall is bent toward the inner surface of the side wall, and the bottom plate is raised.
The left and right connecting flaps are separately fixed to the left and right opening and closing plates, respectively , and are disposed so as to overlap the outside of the end plate.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described based on an embodiment shown in the drawings. FIG. 4 is a development view of the container of the present invention,
In this figure, narrow reinforcing walls 2, 2, side walls 3, 3, and lid plates 4, 4 are sequentially connected symmetrically on the left and right sides of the rectangular bottom plate 1 as a center. At the boundary between the side wall 3 and the cover plate 4, a plurality of parallel ruled lines 6 are formed to form a curved ridge 5.
Is engraved. A reverse crease 10 is engraved on the boundary between the bottom plate 1 and the reinforcing wall 2, and the reinforcing wall 2 is fixed to the inner surface of the side wall 3 via the reverse crease 10 at the time of assembling described later. On the other hand, an end plate 7, a joining flap 8 and an opening / closing plate 9 are connected symmetrically above and below the bottom plate 1, the side walls 2, 2 and the cover plates 3, 3, respectively. The joining flap 8 and the opening / closing plate 9
Is formed substantially as a fan as an example.

[0008]

In assembling the blank sheet cut as described above, first, the reinforcing wall 2 is fixed to the side wall 3 by an existing sack machine or other known box making machine.
The end plate 7 is folded up at a right angle to the bottom plate 1, and then the left and right joining flaps 8 are separately fixed to the inner surfaces of the left and right opening / closing plates 9, respectively, so as to overlap the outside of the end plate 7. I do.

FIG. 1 is a perspective view of the container of the present invention after assembly is completed, FIG. 2 is a state in which the lid of the container is fully opened, and FIG. In order to store a fresh confectionery such as a roll cake or a pound cake in the above-described container, the container shown in FIG.
As shown in FIG. 7, the left and right lids are fully opened using the portion of the reverse crease 10 as a hinge for rotation, and the bottom surface and the side surfaces are rotated to a position where they are substantially in one plane. When the lid is opened in this manner, a resealable container is obtained that has a large opening area and is stable, and can easily store contents, and can easily remove contents.

As described above, the container of the present invention is provided with a reverse crease 10 on the boundary line between the bottom plate 1 and the reinforcing wall 2, and the reinforcing wall 2 is attached to the side wall 3 at the time of assembly through the reverse crease 10. Since the bottom plate 1 is fixed to the inner surface side, the bottom plate 1 is raised by the height h of the reinforcing wall 2 to have a bottom shape. In addition, since the left and right reinforcing walls 2 of the bottom plate 1 are bonded to the side walls 3 to form a double structure, the strength of impact resistance and pressure resistance is enhanced, and the legs of a robust container are formed.
Further, when a plurality of containers of the present invention are stacked using the raised bottom-shaped bottom plate 1 as shown in FIG. 6, the canopy portion of the lower container is fitted and fixed to the raised bottom of the upper container. Therefore, the movement between the containers when the containers are stacked is limited, so that the containers do not move in the left-right direction or the front-rear direction, and it is possible to prevent the containers from collapsing during storage and display.

[0011]

As described in detail based on the above embodiments, the present invention can be assembled with good productivity from a single blank sheet by mechanical bonding, and when the container is opened and the contents are stored or taken out. In some cases, the bottom and side surfaces become one plane and a large opening area is obtained, and at the time of storage and the like, it is possible to stably stack without moving in the left, right, front and rear directions by using the raised bottom,
In addition, the present invention has an effect that a resealable container having a good appearance can be provided.
