PROBLEM TO BE SOLVED: To provide a content dispense mechanism of a pump type container equipped with a pressure accumulation type dispensing valve and having a simple structure which gives user-friendliness and certain and sharp switching operation of a dispensing valve to a pumping product so that cost down and simplifying assembling process of the pumping product can be attained.
SOLUTION: An upper spherical body 9 of the dispensing valve leading to a content dispensing outlet 7a is urged to an upper receiving portion 3g by a coil spring 10 into a closed state. When a user pushes into an operation button 1 in the right direction in the drawing, a linked operation side piston 2 pressurizes contents in a buffer space area A but the upper spherical body 9 does not move upward only by this pressure increase and does not separate from the upper receiving portion 3g. When the operation button 1 is pushed into further, the rear end part of a rear skirt portion 2a forcibly raises the upper spherical body 9 upward from the upper receiving portion 3g and the dispensing valve is opened, and the contents stored in the buffer space area A are dispensed to the outside space area from the content dispensing outlet 7a of the nozzle 7.
