Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a container having an excellent airtight fitting property, and more particularly, to a lid and a container body, lids to each other, container bodies to each other, and a lid to a container. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various types of containers having different depths that can be fitted in an airtight manner by combining main bodies.

[Conventional technology and problems]

Conventionally, the container, depending on the size and amount of the contained object,
That is, it is usual to prepare a large container for accommodating a large object, a small container for accommodating a small object, and the like for the number of contained objects having different sizes and amounts. However, if the lid body and the container body each have a certain depth, and the opening meeting surfaces of both are flat and do not fit when airtight, the lid bodies, the container bodies, the lid body and By combining with the container body, three types of containers with different depths can be provided, but such a container with a flat opening meeting surface is subject to, for example, vibration or slight external pressure even if it is touched a little. The lid comes off just by knocking it off, and it has no practical use.

Thus, as described above, it is necessary to prepare as many containers as the number of contained objects having different sizes, which results in a considerable increase in the cost of the container. In particular, in the case of a disposable container or the like such as for home delivery, it is necessary to reduce the cost as much as possible, but the conventional method of preparing only the number of contained objects has its own limit.

[Means for solving problems]

As a result of earnest research in view of such circumstances, the present invention has completed the present invention by finding that the above problems can be solved by devising the structure of the opening meeting surface of the lid and the container body.

That is, the present invention comprises a rectangular lid and a container body,
The lid body and the container body have an outer peripheral edge, and each opening meeting surface is divided into the same number of plural parts, and each section is provided with a convex portion inside the outer peripheral edge and a concave portion fitted to the convex portion. In each adjacent section, the combination of the convex portion and the concave portion is different from each other, and further, the arrangement of the convex portion and the concave portion is the same in the lid body and the container body. To do.

The present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a lid body and a container body of the present invention with their opening surfaces facing upward,
2 is an enlarged view of the part inside the circle in FIG. 1, and FIG. 3 is A
-A sectional view, FIG. 4 is a BB sectional view, FIG. 5 is a CC sectional view, and FIG. 6 is a DD sectional view.

In these figures, the container of the present invention comprises a lid (1) and a container body (11), the lid (1) having an outer peripheral edge (3).
And the opening meeting surface with the container body is divided into two sections in the middle of each of the vertical and horizontal directions, and the four sections are provided with a convex portion (2
a) and (2a ') and concave portions (2b) and (2b') are alternately arranged.

On the other hand, the container body (11) is provided with an outer peripheral edge (13), and the opening meeting surface with the lid body is similarly composed of four sections divided into two in the middle in the vertical and horizontal directions, and the four sections are convex portions (12a). , (12
a ') and recesses (12b), (12b') are alternately arranged.

In the above, the concave portion is formed in a size capable of fitting and accommodating the convex portion.

As described above, the lid and the container body of the present invention have the same arrangement of the convex portion and the concave portion of each section. Therefore, when the lid body (1) is capped on the container body (11), Is the outer peripheral edge (3) of the lid body (1) and the outer peripheral edge (1) of the container body (11).
3) and the protrusions (2) of the lid (1).
a) and (2a ') are concave portions (12) of the container body (11).
b), (12b ') and also the recess (2) of the lid (1).
b) and (2b ') are convex portions (12) of the container body (11).
a) and (12a ′), respectively, resulting in a zigzag fitting structure of outer peripheral edge-projection (or recess) -recess (or projection), and the lid (1) is airtight. Container body (1
Be crowned 1).

In the present invention, the division of the lid body and the container body is not particularly limited, but if the number is too large, it becomes difficult to fit the protrusions and recesses due to molding distortion and the mold design becomes complicated. It is appropriate to divide into two at the center and the above-mentioned four.

The container of the present invention is preferably made of synthetic resin or foamed synthetic resin in terms of moldability.

7 to 9 respectively show the container of the present invention, FIG. 7 shows a combination of the original lid body (1) and the container body (11), and FIG. 8 shows the lid body (1) 2 FIG. 9 shows a combination of two container bodies (11). That is, by preparing two molds for the lid and the container body, it is possible to provide three types of containers having different depths and having airtightness. According to the present invention, for example, if another mold for a lid or a container body having different depths is prepared, and a total of three molds are prepared, the depths will be different,
It is possible to provide 6 types of airtight containers, and similarly, if 4 molds are prepared, 10 containers can be provided.

Although the present invention has been described above in the case where the lid body and the container body have different depths, respectively, the depths may be the same, and in this case, the container having excellent airtight fitting property. Can be provided.

[Action / effect]

As described above, according to the present invention, it is possible to provide a container having a high airtight fitting property, and further, by making the depth of the lid body and the container body different, the depth can be changed with a small number of molds, It is possible to provide a large number of airtight containers that exceed the number of molds, and it is possible to provide inexpensive containers.
