Abstract
A squeezebottle dispenser having an inner flexible bag containing a viscous fluid in fluid communication with a dispensing nozzle. A vent hole is provided in the squeezebottle side wall which is blocked by the user to prevent air from exiting the squeezebottle during squeezing so that air compression within the squeezebottle forces the inner bag to discharge its contents through the dispensing nozzle. When the squeezebottle is released, the vent hole is unblocked in order to vent air into the squeezebottle so that the squeezebottle may return to its unsqueezed shape. The vented air entering an air space located between the squeezebottle and the inner bag replaces the volume of the contents discharged from the inner bag. The addition of a recessed channel, formed between the vent hole and a venting point, which is covered with a compliant film to form an air passage, enables the user to block the vent hole indirectly. When the compliant film is pressed into and against the recessed channel anywhere along the air passage, air cannot escape from inside the squeezebottle, thereby enabling air compression to occur inside the squeezebottle.
