Description

請求項７に係る容器によれば、容器は、内容物を収容する可撓性の内部容器と、内部容器を内包する外部容器とを有し、外部容器には、内部容器と外部容器との間に外気を吸引可能な吸入弁が設けられているため、外部容器を押圧して内部容器内の圧力を高め内容物を吐出した後、外部容器の押圧を解除すると、内容物の吐出に伴い減少した外部容器内の体積を、吸入弁から外気を吸引することで補填し外部容器のみ復元することができるため、容器の外観形状を変えることなく最後まで同じ使用感で内容物を吐出することができる。
また、外部容器が形状を復元していく間、外部容器内は負圧状態であるため、吸入弁が外気を吸引し終わるまでの間、弁室に残留している内容物は回収流路から内部容器へ吸引され、十分に内容物を回収することができる。 According to the container according to claim 7, the container and the inner container flexible housing the contents, and an external container which encloses the inner container, the outer container, the inner container and the outer container Since there is a suction valve that can suck the outside air in between, after pressing the outer container to increase the pressure in the inner container and discharging the contents, the release of the outer container will release the contents. The reduced volume in the external container can be compensated by sucking outside air from the suction valve and only the external container can be restored, so that the contents can be discharged with the same feeling to the end without changing the external shape of the container. Can do.
Also, since the external container is in a negative pressure state while the outer container recovers its shape, the content remaining in the valve chamber is removed from the recovery channel until the intake valve finishes sucking outside air. It is sucked into the inner container and the contents can be recovered sufficiently.

Claims

A container that fits into the discharge cap according to any one of claims 1 to 6,
The container has a flexible inner container that contains the contents, and an outer container that contains the inner container,
The outer container is provided with a suction valve capable of sucking outside air between the inner container and the outer container.
