蓋との嵌合構造となっている。2. Description of the Related Art Conventionally, such a simple plastic food container is shown in FIG. It consists of a combination of a thin plastic container body A and a lid B. When fitting the lid B to the container body A, as shown in FIG. 5, the elasticity of thin plastics is used to improve the sealing performance, and the container body and lid are fitted so that the stored food does not spill out. It has a composite structure.

The outer peripheral edge of the has an extending portion a 1 extending downward, and further has an upper edge a provided with a hanging protrusion a 2 protruding outward at the lower end thereof. Further, the lid B is provided with a lower edge b having an extended portion b 1 extending downward at the outer end, and further, the fitted lid B can be easily removed on a part of the outer periphery of the lower edge b. An ear member b 2 is provided for this purpose.

は解除される。Then, by covering the lid B from above the container body A, the inner surface of the lower edge b of the lid B is changed to the upper edge a of the container body.
Along the outer surface of the lid, so that the extended portion b extends below the lower edge b of the lid as shown in the partially enlarged view of FIG.
The inner surface of 1 is fitted so as to wrap around the hooking protrusion a 2 of the upper edge a of the container body A, and the lid B integrally covers the container body A, and the contents stored in the container body A are sealed. The stored items will not spill outside. When the lid is opened, the hooked state between the lower edge b of the lid and the upper edge a of the container body is released by pulling the ear member b 2 attached to the lid.

じる。However, in the case of a container having such a structure, in actuality, in order to cover the container with the lid, the lid must be fitted exactly to the container body and the lid must be pressed down. However, this was a trouble in storing the food. Further, when the lid member is removed, if the ear member b 2 is pulled, the fitting on the opposite side becomes tight, and if the fitting state is loosened to improve the ease of opening, the seal will be insufficient and the storage There is a problem that the food tends to spill.
【０００６】この発明の課題は、容器本体と蓋との間の

実に行なうことができる。As described above, in the fitting structure of the present invention, when the lid 2 is put on the container body 1, the unevenness 23 of the lid 2 is formed.
Hold lightly with your hand and push it in the direction of the arrow. Then, the lower end 22 of the extending portion 21 extending downward around the lower end of the lid 2 comes into contact with the upper surface of the extending portion 12 inclined outward from the upper edge of the container main body and slides down, so that the elasticity of the plastic itself causes it. The extending portion 12 is forcibly expanded, and the hooking protrusion formed on the lower end 22 of the extending portion 21 has the rising portion 1 at the tip of the extending portion 12 of the container body 1.
Inside the recess 13 provided inside 3, further, the recess 15 for locking
It goes in and the lid 2 is hooked and fixed to the container body 1. On this occasion,
By bending the inner side edge 16 of the container body 1 inward as shown as d and forming the unevenness 23 on the upper edge inclined surface of the lid 2, the lid 2 can be reliably gripped, and the container 2 can be held relative to the container body 1. The target movement becomes large, and it is possible to securely cover and remove the lid.
