Abstract

PURPOSE: To provide a container which can be simply folded after use and can be abandoned under a compact condition. CONSTITUTION: A container for packaging consists of a bottom face 1 and a side face 2 with a slope and each one line groove 3 is formed on the right side part and the left side part of the bottom face as the center. These line grooves 3 are formed in such a way that they continuously exist between two upper side edge parts facing each other on the side face 2 and two line grooves 3 become closer as they approach to the upper side edge.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention relates to a cup-type packaging container for containing instant noodles, a shallow-sealing packaging plate for selling prepared foods and the like, and then folding and discarding after use. The present invention relates to a foldable packaging container formed so as to be capable of being folded.

[0002]

2. Description of the Related Art Heretofore, the above-mentioned cup-type packaging container, packaging dish, etc. have been formed of thick Styrofoam.

[0003]

By the way, even though such a packaging container is disposable, it is formed so as not to lose its shape due to its application. Therefore, it is difficult to put them together compactly when they are discarded after use, and it is difficult to handle and wastes a space. The present invention has been developed in view of the above circumstances, and an object thereof is to provide a packaging container that can be easily folded after use.

[0004]

In order to achieve the above object, according to the present invention, in a packaging container having a bottom surface and a slope, one line groove for folding is provided on each of the left and right sides of the bottom surface as a center. The line groove is formed continuously between two opposing upper edge portions on the side surface, and the two line grooves are formed so as to be closer to each other toward the upper edge. Further, in the above configuration, the line groove is formed in a concave arc shape that is continuous from one upper edge of the side surface to the bottom surface, and is adjacent to the bottom surface, and is further upward and facing each other.
Further, the line groove is formed downward from one upper edge of the side surface to reach the boundary line between the bottom surface and the side surface, along the boundary line, and further continuing to the other upper edge part facing each other.

[0005]

Embodiments will be described below based on the illustrated embodiments.
1 to 3 show a first embodiment. The first embodiment relates to a cup-shaped packaging container having a relatively shallow bottom that contains instant noodles and the like, and has a round bottom surface 1 and an inclined side surface 2. Is provided with two line grooves 3 for bending. The line groove 3 is formed in a concave arc shape that is downward from one upper edge 2a of the side surface 2 and is close to the bottom surface 1 and is continuous between the other upper edge portions 2b facing upward. 2 are provided one by one, and these two line grooves 3 and 3 are provided on the upper edge portions 2a and 2 of the side surface 2, respectively.
It is symmetrically provided so that it gradually approaches as it goes to b.

4 to 6 show a packaging container according to the second embodiment. This second embodiment relates to, for example, a packaging plate having a shallow bottom used for selling prepared foods and the like over the counter. On the boundary line between the bottom surface 4 and the side surface 5 and on the side surface 5, two line grooves 6 for bending are provided.

The line groove 6 has an upper edge 5 on the side surface 5 in the width direction.
It is provided diagonally downward from a toward the corner portion of the boundary line 7 between the bottom surface 4 and the side surface 5, is continuously provided along the boundary line 7 in the length direction, and is diagonally upper edge on the opposite side surface 5. 5
It is provided in the shape of a polygonal line provided toward b and is provided one by one with the bottom surface 4 as the center, and the two line grooves 6, 6 are gradually close to each other on the two side surfaces 5, 5 toward the upper edge. , Provided symmetrically.

For disposal after use, in the first embodiment, the left and right sides of the side surface 2 are folded along the line groove 3 toward the bottom surface 1 respectively, and in the second embodiment, along the line groove 6 and the left side surface 5. , If the right side is folded in the direction of the bottom 4 respectively, the container becomes compact and is discarded in the compacted state.

Although the present invention has been described with reference to an embodiment of a styrofoam packaging container, the present invention is not limited to this, and the present invention is also applied to a cup-type packaging container using a foldable material such as paper. It is possible.

[0010]

As described above, according to the present invention, since two line grooves are provided between the upper edges of the two side surfaces facing each other in the side surface portion of the packaging container, after use, it is folded along these line grooves. It can be easily made compact. Therefore, it has advantages that it is compact and not bulky, it is easy to carry, it can be discarded without needing a wasted space, and it can contribute greatly to the prevention of dust pollution. In addition, the two line grooves are formed so that they approach each other toward the upper edge of the side surface and are folded so as to be folded back in the direction opposite to the inclination direction of the side surface, so that the part that was once folded should not be opened again. Fixed to.
