Abstract

A liquid container comprising: a holder sleeve; a cylinder for forming a pressurized chamber, said cylinder being axially movable; a cylinder cam for axially moving said cylinder by rotating said holder sleeve; and projections axially movable between said holder sleeve, said cylinder being engaged with said cylinder cam. The liquid contained in the container can be supplied to a liquid applicator means not only by pushing in a push button provided at the bottom of the container but also by rotating the holder sleeve.
