ABSTRACT:
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 container1having an outer layer2,an inner layer3laminated with the outer layer2,a container neck6disposed on top of the container1and used as the flow path29for the contents, and an air intake13used to introduce outside air into the void between the outer layer2and the inner layer3;an applicator70having an applying mechanism and discharge holes74for discharging the contents, and having discharge passage76communicated with the neck6;the second check valve mechanism41that acts to open or close the flow path29so as not to allow the backflow of the contents and the entry of outside air; a base cup50having a bottom of its own, a cylindrical wall51,which is fitted around the bottom cylinder8,and an air hole54that introduces outside air into air intake13;and the first check valve40,which is assembled with and fitted to the base cup50so as to allow outside air to pass through the air intake13but not to allow the backflow of introduced air.
