Abstract

A container includes a container body; and a cap that locks onto the container body, the container body and the cap being locked by putting the cap on the container body. The cap includes a cap body, a cover cap being held on the cap body so as to be displaceable and rotatable, and an urging portion that upwardly urges the cover cap. When a rotational force is applied to the cover cap being downwardly pressed, the cap body is displaced in conjunction with the cover cap, so that locking between the cap body and the container body is released, and in a state where the cover cap is not downwardly pressed, the cap body is not displaced in conjunction with the cover cap even when a rotational force is applied to the cover cap, so that locking between the cap body and the container body is not released.

First claim

The invention claimed is:

1. A container comprising:
a container body having an opening portion; and
a cap that closes the opening portion and locks onto the container body,
the container body and the cap being locked by putting the cap on the container body and pressing the cap toward a direction of the container body,
wherein the cap includes a cap body having a cap locking portion that locks the cap onto the container body, a cover cap that covers the cap body and is held on the cap body so as to be displaceable and rotatable in an up-down direction with respect to the cap body, and an urging portion that upwardly urges the cover cap,
the cap body and the cover cap have respective positioning portions for positioning the cover cap at a predetermined position in a rotational direction of the cover cap with respect to the cap body,
the positioning portions are configured to release the positioning of the cover cap and allow the cover cap to rotate when a rotational force is applied to the cover cap not being pressed down,
the cover cap includes an inner surface to be opposed to an outer surface of the cap body only when the cover cap is pressed down against an urging force of the urging portion from the predetermined position,
when the cover cap is pressed down against the urging force of the urging portion and a rotational force is applied to the cover cap from the predetermined position, the inner surface of the cover cap comes into contact with the outer surface and rotates the cap body in conjunction with the cover cap to thereby release locking between the cap body and the container body, and in a state where the cover cap is not downwardly pressed against the urging force of the urging portion, the cap body is not displaced in conjunction with rotation of the cover cap so that locking between the cap body and the container body is not released when a rotational force is applied to the cover cap, and
in the state where the cover cap is not pressed down against the urging force of the urging portion, the cover cap rotates in non-conjunction with the cap body in a first rotational direction or a direction opposite to the first rotational direction.

2. The container according to claim 1 , wherein the cap body has a base portion to which the cover cap externally fits, the external fitting causing the cap body to work in conjunction with the rotation of the cover cap.

3. The container according to claim 1 , wherein
the container body has a guide portion which, when a rotational force is applied to the cover cap being pressed downwardly against an urging force of the urging portion, contacts the cap body that works in conjunction with the cover cap, to displace the cap body, and
the cap body goes on the guide portion to be displaced, so that locking between the cap body and the container body is released.

4. The container according to claim 1 , wherein
the container body has a regulating portion that contacts the cap body, and
in a state where the cover cap is pressed downwardly against an urging force of the urging portion, when a rotational force is applied to the cap body, application of a rotational force to the cover cap in the first rotational direction displaces the cap body in conjunction with the cover cap, so that locking between the cap body and the container body is released, and application of a rotational force to the cap body in the direction opposite to the first rotational direction causes the cap body to contact the regulating portion and refrain from being displaced, so that locking between the cap body and the container body is not released.

5. The container according to claim 1 , wherein
the rotation of the cover cap with respect to the cap body causes one of the positioning portions to come into contact with another of the positioning portions and releases the positioning due to elastic deformation of at least one of the positioning portions.

6. The container according to claim 1 , wherein
the container body and the cap our flat and generally rectangular or oval in section,
the cap body has a hood that is cylindrical and closes the opening portion of the container body, and a base that extends outwardly from one end of the hood on the container body side along the container body, and
the rotation of the cover cap with respect to the cap body causes one of the positioning portions to come into contact with another of the positioning portions so that the cover cap goes on the base portion of the cap body to release the positioning.

7. The container according to claim 1 , wherein
the cover cap has a ceiling surface in an inside upper portion of the cover cap,
the cap body has an upper end surface opposed to the ceiling surface, and
the urging portion is an elastic bending piece formed integrally with the upper end surface or the ceiling surface to be interposed between the upper end surface and the ceiling surface in a state of being compressed in the up-down direction.

8. The container according to claim 1 , wherein
the container body has a tubular neck portion and a nozzle port, and
the cap body includes a stopper portion which is inserted into the nozzle port to close the nozzle port.

9. The container according to claim 1 , wherein
the container body and the cap are flat and generally rectangular or oval in section, and
the positioning portions hold the cover cap and the cap at the predetermined position where an outer circumferential surface of the cover cap and an outer circumferential surface of the container body are substantially continuous with each other.
