Abstract: Disclosed is a side-push type of container appropriate for use for instance, in a cosmetic applicator, permitting application of a cosmetic liquid material such as varnish to selected parts of a human body such as nails without using both hands for holding the separate parts of the cosmetic applicator, simply by using a forefinger of the hand holding the applicator to feed a predetermined amount of cosmetic liquid material to the applicator tip. It comprises a hollow container body having a depressible push button on its side, an application member partly inserted into the hollow container to expose the remaining part therefrom, and a valve mechanism responsive to depression of the depressible push button for feeding the application member with a fixed amount of liquid material.
