    摘要: A container for holding a viscous liquid medium and from which the same may be selectively dispensed in a desired amount includes a rigid body having a deformable top portion and carrying a dispensing mouthpiece. The application of an inwardly-directed force to the mouthpiece deforms the container top portion and causes displacement of the mouthpiece partially into the container interior such that valve openings in the mouthpiece that are normally disposed sealingly within a valve body in the interior of the container are carried to a position remote from and clear of the valve body to clear the valve openings and permit a dispensing flow of liquid through the mouthpiece and thereby out of the container body.
