DESCRIPTION OF PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a developed plan view of the container according to the first embodiment of the present invention. Reference numerals 1 and 1'refer to two side walls having substantially the same shape and dimension, and each of the side walls 1 and 1'includes two straight sides 3, 4 and 3 ', 4'that intersect each other at an acute angle θ. And the straight sides 3 and 3'or the straight sides 4 and 4'may be integrally formed from the beginning, or may be formed by bonding the separately formed sides. But in any case,
The side walls 1 and 1 ′ are continuous with each other via the corresponding straight sides 4 and 4 ′, and the other corresponding straight sides 3 and 3 ′ are the straight sides 4,
The side walls 1 and 1 ′ are folded and overlapped at the boundary 4 ′, and the side walls 1 and 1 ′ are overlapped and bonded by an adhesive or the like to form a food storage portion between the side walls 1 and 1 ′. Each of the side walls 1 and 1'has a concave arcuate fold CD, C'D 'facing the intersection P of the straight sides 3, 3'and 4 (4'), and an outwardly convex shape substantially symmetrical with the arcuate fold. With arched edges EF, E'F ', and a bowed fold CD,
The portions 5 and 5'surrounded by C'D 'and the arcuate edges EF and E'F' constitute a folding piece which can be a lid which can be opened and closed with the arcuate folds CD and C'D 'as pivot axes, Side wall 1, 1 '
A breaking means 7 (GG ') is formed across each of the straight sides.

The acute angle θ is preferably in the range of 15 degrees to 45 degrees, and particularly preferably in the range of 30 degrees to 45 degrees. This is because if the angle is too small, the storage volume becomes small, and if it is too large, it is difficult to hold by hand.

In the preferred example of FIG. 1, the length L1 of the straight sides 4 and 4'is longer than the length L2 of the straight sides 3 and 3 ', but they may have the same length. The ratio L2 / L1 of this length is 1 ≧ L2 / L1 ≧ 0.6
Is preferred, and it is particularly preferred that it is in the range of 1 ≧ L2 / L1 ≧ 0.8.

If this ratio is too small, the food storage volume becomes small, and if it is too large, it is inconvenient to grasp by hand during the breaking operation of the container.

As the material of the side wall, there is a shape-retaining and breakable material, for example, cardboard, corrugated cardboard (including single corrugated cardboard), various synthetic resins such as polyethylene and polystyrene,
A synthetic resin foam material such as polyethylene, polystyrene or polyuretin, or a laminate of paper and a synthetic resin such as polyester or nylon is preferable. Further, in that the molding is easy and preferable strength is obtained after molding, the thickness is 0.15 mm to 0.60 mm,
Preferably, it is formed of thick paper of 0.20 mm to 0.40 mm. It is preferable to use corrugated cardboard or synthetic resin foam material because heat insulation and heat retention can be obtained.

The breaking means {circle around (1)} may be composed of a series of intermittent elongated through holes or slits, a series of intermittent elongated thin portions, or perforations. In short, one end 8 (G =
G ') is used as a fulcrum, and any straight line 4 = 4' can be bent by the action of a lever so long as it can easily start to break from the midpoint H of {circle around ()} and break.

The breaking means ▲ ▼ ′ bifurcates from K, K ′ near one straight side 4 (4 ′) to facilitate breaking, that is, ▲ ▼ and ▲ ▼, and ▲ ▼ and ▲.
It is preferable to branch to ▼ respectively.

In the first embodiment shown in the exploded view of FIG. 1 and the perspective view of FIG. 2, between the ends C (C ′) and D (D ′) of the arcuate fold and the end A (A ′) of the straight side, And between the ends of the arcuate fold and the corresponding ends of the arcuate edge E (E '), F (F'),
Since each of them has a straight edge, the container has a large thickness and can store thick foods, and therefore has an advantage of a large volume.

However, when it is not necessary to increase the volume so much, these straight edges may be eliminated as in the second embodiment shown in the developed view of FIG. 3 and the perspective view of FIG. That is, both ends of the arcuate fold, corresponding ends of the arcuate edge, and corresponding ends on the opposite side of the intersection of the straight sides may be located at one point. In this case, A = C = E, A '= C' =
E ′ and B = D = D ′ = E = E ′, respectively, so that they coincide with each other.

In the embodiment described above, the sidewalls 1 and 1'are formed from a single sheet and are folded along side 4 (4 ') to join sides 3 and 3'. It is convenient for joining that the sheets are cut by providing the margin 6 along the side 3. The folded portion along the side 4 (4 ′) and the joined portion of the sides 3 and 3 ′ are easier to break by the breaking means if they have a corner, but may be rounded. As mentioned above, the basic shape of the container is an inverted cone.

Modes of Use and Actions First, the container is provided to a force food store or the like with the sides 3 and 3'attached only with the glue allowance 6 shown in Figs. The folding pieces 5 and 5'have not been folded yet, and the upper part of the container is open.

This container is filled with food such as crepe at a Forth Foods store or the like, and the folding pieces 5 and 5'are bow-shaped fold CDs,
The container is folded along C'D 'to form the upper surface of the container to substantially seal the container and provide it to the customer.

When the upper surface of the container is formed as described above, appropriate strength is added to the container, whereby the customer bends the container at the breaking means 7 as a boundary and the breaking means 7 is provided as shown in FIG. The container can be easily broken and opened by using the part 8 of the portion as a fulcrum, and the upper part of the container can be removed.

The above operation exposes the upper part of the food and eats it. The strength of the container portion left after the rupture is reduced in the circumferential direction of the container, and the food can be fixed by sandwiching the container portion.

Effect Since the present invention has the above-described configuration and operation,
It can be used for both takeout and eating in the same container, it is easy to fill food, seal and open the container, and one-hand eat utilizing elasticity is possible. Therefore, it is suitable for providing FF menus that are prepared and filled right in front of the customer and are intended for standing on the street.
