Patent ID: 8245887

Claim:
A content discharge mechanism of a pump type container comprising: an operation part located on top, a first cylindrical part having an inner surface comprising: a piston having an annular sealing part formed on the outer surface of said piston and interlocking with said operation part; a suction valve actuated in response to the movement of the piston; a means for elastically energizing the operation part in the longitudinal direction with respect to the operation part; an upstream side passage formed between said piston and said suction valve; a second cylindrical part perpendicular to the first cylindrical part comprising: a discharge outlet; a downstream side passage reaching said discharge outlet from a communication hole with said upstream side passage, said communication hole formed in the perpendicular intersection of said first cylindrical part and said second cylindrical part; a movable discharge valve provided on said downstream side passage, acting on said discharge outlet and having a means for elastically energizing in the lateral direction with respect to the operation part; and a discharge outlet setting member integrated with an opening cap of the container for setting said discharge outlet in the state where it does not move even at the time of the actuation of said operation part, wherein said annular sealing part of said piston advances together with said operation part from its stationary mode and the content discharge mechanism is not shifted from a discharge mode to a discharge finishing mode until the annular sealing part reaches the communication hole.
