ABSTRACT:
A squeeze dispenser for liquids, preferably relatively highly viscous liquids, is provided with a flexible holder (1) with an outflow opening (2) via which a liquid can be pressed out of the holder, and with a sealing element (3) arranged over this outflow opening. In this sealing element, a first valve (12) is arranged via which, when the holder is squeezed, liquid can be pressed out of the holder, as well as a second valve (18) for admitting air into the holder when the holder is no longer squeezed.
