BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap and a container, and more particularly to a cap and a container whose contents are expensive lipsticks or other cosmetics.
The present invention relates to a cap having a child resistance function such that a child or the like who cannot understand a dangerous drug or the like cannot easily open the cap unnecessarily.

[0002]

2. Description of the Related Art A conventional container has a structure in which a cap is screwed into a container mouth portion or simply fitted so that the cap is attached to protect the contents. Such a configuration is the same even if such a container is used for storing expensive cosmetics or filling dangerous drugs, and in many cases, it can be easily opened.

In particular, many containers for storing lipsticks have a simple fitting structure so that the cap can be easily removed immediately when it is desired to use the lipstick. I can say.

[0004]

However, since the emphasis has been placed solely on the ease of removal and mounting of the cap as described above, the operation of simply pulling the cap results in
This cap can be easily removed by anyone, and the contents can be taken out freely.

[0005] In normal use situations, where the user fully understands the value and properties of the contents to be stored or filled, the ease of removal of such a cap is convenient and without any problems. Also, although desirable, there is a concern that even those who do not fully understand the value and properties of the contents to be stored or filled can easily remove the cap.

That is, for example, it is possible that the cap of the container is removed and the contents are mischieved without imitating the value and danger of the contents by imitating the behavior of the surrounding adults such as the mother. In particular, lipstick and other cosmetics can be a good prank object for children, even if they are used for makeup. Lipsticks are often ruined.

[0007] In order to cope with such problems, a container for storing or filling expensive contents such as lipstick or a cap for the container cannot easily be removed by a child.
That is, it is required to provide a so-called container child resistance function. The cap and the container having the child resistance function are, for example, a cap of the prior art that can be removed by simply pulling the cap in a direction of separating the cap and the main body of the container, whereas a cap simply by pulling the cap. Before removing the cap or at the same time pulling the cap, perform another operation on the cap etc.
Caps and containers which are thereby configured to remove the cap, i.e. are not easily removed by children.

[0008] At this time, the operation performed on the cap or the like for the child resistance function is not too complicated as compared with the conventional cap and container removing operation, and the conventional cap can be easily removed. It must be sufficient to prevent children from trying to remove them by mischief.

Accordingly, an object of the present invention is to provide a novel cap and a container which solve the above-mentioned problems, that is, it is possible to sufficiently remove the conventional cap, and to play with children.
