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.

Abstract: A liquid applicator structure which has an application tip fixed to front end of a cylindrical body and a liquid supply assembly built in its rear end. The liquid supply assembly includes a rotatable rod composed of a cylindrical shank-and-operating end and a solid rod having male threads thereon. The rotatable rod is held with an anti-rotation member having a cantilever-like extension. A split slide member having two split extensions is engaged with the rotatable rod at its rear end. One of these split extensions is inserted within the cantilever-like extension of the anti-rotation member and the rotatable rod, thereby preventing the split slide member from rotating. A piston member abuts on the split slide member. Rotation of the rotatable rod causes the split slide member and the piston to advance and drive liquid toward the application tip.
