ポンプ式吐出容器
Document Type and Number:
Japanese Patent JP5603734
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pumping discharge container which can reduce liquid leakage from a discharge nozzle after liquid discharge.SOLUTION: This pumping discharge container involves the following components: a check valve which is additionally arranged to one spot for controlling the opening/closing of a primary valve, aside from a check valve at the lower end of a rod part; a stopping part with an enlarged diameter which is arranged at the upper end of the rod part; a secondary valve which is so constituted that the interior of a liquid chamber can be completely closed by the stopping part of the rod part and a separately arranged cylindrical valve seat part coming into contact with each other, when a nozzle head has reached its ascent end. Therefore, even in the case that the internal pressure of the liquid chamber has climbed, after discharging the liquid, it is possible to significantly reduce the liquid leakage after discharge, without the opening of the secondary valve.
