Abstract

A compact container is the adjustment of a discharge amount of contents is easy. A compact container includes an inner container; an inner lid in which a communication hole is formed; a middle lid in which a discharge hole is formed; a first valve body; and a second valve body. When the inner pressure of the communication space is increased by the operation portion, the first valve body blocks communication between the communication hole and the communication space and the second valve body allows the discharge hole and the communication space to communicate with each other. When the inner pressure of the communication space is reduced by the operation portion, the second valve body blocks communication between the discharge hole and the communication space and the first valve body allows the communication hole and the communication space to communicate with each other.

First claim

The invention claimed is:

1. A compact container comprising:
an inner container in which contents are accommodated;
an inner lid which seals an inside of the inner container, the inner lid including a communication hole communicating with the inner container;
a middle lid which is disposed above the inner lid, the middle lid defining a communication space communicating with the communication hole between the middle lid and the inner lid, and the middle lid including a discharge hole communicating with the communication space and discharging the contents from the communication space;
a first valve body which switches between communication and blocking of flow of contents between the communication hole and the communication space; and
a second valve body which switches between communication and blocking of flow of contents between the discharge hole and the communication space, wherein:
the middle lid includes an elastically deformable operation portion which defines the communication space, the operation portion increases or decreases an internal pressure of the communication space by being elastically deformed, and the operation portion includes an annular thin portion formed by indenting a lower surface of the operation portion upward,
when the internal pressure of the communication space is increased by the operation portion, the first valve body blocks communication between the communication hole and the communication space, and the second valve body allows communication between the discharge hole and the communication space, and
when the internal pressure of the communication space is decreased by the operation portion, the second valve body blocks communication between the discharge hole and the communication space, and the first valve body allows communication between the communication hole and the communication space.

2. The compact container according to claim 1 , further comprising an outer shell which covers the inner container, the inner lid and the middle lid, wherein
a volume of the inner container is reduced as the contents flow out of the inner container into the communication space through the communication hole.

3. The compact container according to claim 1 , further comprising a biasing portion which biases the operation portion upward when the operation portion has moved downward.
