摘要:
The technical problem of this invention is to create check valve mechanisms of a simple configuration. Thus, the object of this invention is to provide a discharge container maintaining high productivity, showing good squeeze operation, and having improved outer appearance. The above technical problem and the object of this invention are solved and achieved by a discharge container comprising: a squeezable container 1 having an outer layer 2, an inner layer 3 laminated with the outer layer 2, a container neck 6 disposed on top of the container 1 and used as the flow path 29 for the contents, and an air intake 13 used to introduce outside air into the void between the outer layer 2 and the inner layer 3; an applicator 70 having an applying mechanism and discharge holes 74 for discharging the contents, and having discharge passage 76 communicated with the neck 6; the second check valve mechanism 41 that acts to open or close the flow path 29 so as not to allow the backflow of the contents and the entry of outside air; a base cup 50 having a bottom of its own, a cylindrical wall 51, which is fitted around the bottom cylinder 8, and an air hole 54 that introduces outside air into air intake 13; and the first check valve 40, which is assembled with and fitted to the base cup 50 so as to allow outside air to pass through the air intake 13 but not to allow the backflow of introduced air.
