Abstract

The invention provides a foam-dispensing pump container which is improved when the foam or liquid backflows to the inside of a pump after being dispensed to reduce the usability. The foam-dispensing pump container according to the present invention has the valve seat portion which protrudes inwardly below the air-liquid mixing unit and which is formed of the flexible member that can come into contact with the outer peripheral face of the latch portion of the rod-shaped valve body, and immediately after the nozzle head starts rising, the flexible valve seat portion comes into contact with the rod-shaped valve body before the upper opening end of the liquid chamber comes into contact with the rod-shaped valve body, thereby significantly reducing a backflow of the foam or liquid into the air passage, and consequently improving the usability of the foam-dispensing pump container.

Description

technical field [0001] The present invention relates to a pump-type foam spray container that sprays foam from a foam spray port, and particularly relates to the improvement of the situation where the foam or liquid flows back into the pump after the foam is sprayed, resulting in a drop in usability. The foam is formed by mixing the air and the foaming liquid in the body of the container by depressing the nozzle head out of the container. Background technique [0002] Conventionally, containers of various structures have been proposed as pump-type foam ejection containers. In this pump-type foam ejection container, the nozzle head of the nozzle body provided on the upper part of the container body is pressed down to release the foam contained in the container body. The liquid is mixed with the air sucked from the outside of the container to form foam, and the foam is sprayed out of the container through the foam passage inside the nozzle head. In addition, in such a convent...
