Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a creamy substance dispensing container for dispensing a stored creamy substance under pressure.

"Prior Art" For example, the container described in Japanese Patent Laid-Open No. 56-95870 has a cylindrical container body in which a cylinder is erected from the upper end of the cylinder body, and a lower end portion is fitted in a watertight and vertically slidable manner on the inner surface of the upper portion of the cylinder. It is formed on the upper end portion inside the pressure cylinder, the combined pressure cylinder, the nozzle fitted to the outer surface of the upper end portion of the pressure cylinder, the spring for urging the nozzle and the pressure cylinder upward. It is composed of a discharge valve and a bottom plate slidably fitted to the lower part of the inner surface of the cylindrical container body, and resists the bias of the spring and pushes down the pressure cylinder via the nozzle to The cream container is formed so as to be pressurized and discharged from the nozzle.

[Problems to be Solved by the Invention] The conventional container described above has a drawback that it requires a little force to push down the pressure cylinder because the pressure cylinder is pressed down against the bias of the spring.

The idea is to make it easier for the pressurizing cylinder to be pushed down by the push-down lever, and to make the nozzle protrude from the window hole formed in the push-down lever, which makes it difficult for the discharge cream to adhere to the push-down lever. It is provided so that it can be formed at low cost by using a small number of parts.
