The lid can be closed and opened with one touch on the container body. It concerns a container. 2. Description of the Related Art In containers used for tablets, granules, powders, and the like, there are many methods for closing and opening a lid on a container body by a screwing method. A female screw is formed inside the side wall of the lid, and a male screw is formed outside the side wall of the mouth of the polyethylene terephthalate container body. The method of closing and opening the cover was common. However, the method of closing the lid on the container body by screwing the male screw and the female screw is such that the lid is closed until the top plate of the lid and the upper edge of the opening of the container body come into contact with each other and are sealed. It was necessary to rotate, and the rotation stroke of the lid was extremely long.
In addition, the end position of the screwing differs depending on the strength of the tightening torque, is very unclear, and may cause an overrun (idling). For this reason, many proposals have been made to make the rotation stroke of the lid as short as possible and to fix the final position of the lid. For example, Japanese Utility Model Application Hei 6-760
No. 84, the lid is closed and opened on the container body by a convex portion provided on the inner surface of the side wall of the lid, and an engaging convex portion and a fixing convex portion provided on the outer surface of the side wall of the container body. A method of capping is disclosed. [0003] However, the method of closing and opening the lid on the container main body by the above-mentioned convex part of the lid and the engaging convex part and the fixing convex part of the container main body, Although the rotation stroke is short and the final position of the lid is fixed,
The engagement force of the lid with the container body was weak, and the click feeling (feeling of closing the lid) was lacking, and it was not satisfactory in terms of function. The present invention has been made to solve the above-mentioned conventional problems, and has a short rotation stroke of the lid when the lid is closed and opened, and the lid can be closed and opened with one touch on the container body.
An object of the present invention is to provide a container which has a strong engaging force of the lid with respect to the container main body, firmly fixes the lid at the final position when the lid is closed, has a good click feeling, and is sufficiently functionally satisfactory. The present invention relates to a container comprising a cylindrical lid and a blow-molded container body having a cylindrical mouth, as shown in FIG. )
