Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a creamy material dispensing container for pressure-dispensing a creamy material.

[0002]

[Prior art]

[Problem to be solved by the present invention] For example,
The container described in Japanese Patent No. 150767 includes a container body having a partition wall formed on an upper inner surface of a body, a bottom plate fitted to an inner surface of a lower portion of the body so as to be raised by negative pressure in the body, and a body. An elastic dome wall stretched at the upper end, a nozzle with a discharge valve communicating with the inside of the elastic dome wall, an operating plate for compressing the elastic dome wall integrally connected to a lower outer surface of the nozzle via a thin hinge, It comprises a suction valve provided on the partition wall. The compression and opening of the elastic dome wall allows the creamy substance in the body to be sucked into the elastic dome wall and discharged from the nozzle.

[0003] However, the conventional container has a disadvantage that the structure is rather complicated and cannot be formed at a low cost. In addition, since the nozzle and the operation plate are close to each other, there is a problem that the nozzle is liable to become an obstacle during the pressing operation, and that the cream-like substance is easily attached to the fingertip by mistake.

[0004] In the present invention, the structure is simplified by using a single valve element for the valve element for the discharge valve and the valve element for the suction valve.
The present invention relates to a container which can be formed at a low cost and in which a nozzle does not obstruct a pouring operation.
