Squeezable containers with integrated valve for multidose dispensing

Abstract

In some embodiments, a system for dispensing a fluid includes a dispensing plug and a squeezable container for receiving the dispensing plug and storing the fluid. The dispensing plug includes a one-way valve for dispensing the fluid. The squeezable container includes a squeezable wall, an opening for dispensing the fluid that is sealed airtight by the dispensing plug, an air-return hole in the squeezable wall, and an air-return valve that is permeable to air and impermeable to the fluid and that closes the air-return hole. The fluid leaves the squeezable container through the one-way valve of the dispensing plug in response to exerting a pressure onto the squeezable wall, and air enters the squeezable container through the air-return valve upon expansion of the squeezable wall in response to releasing the pressure onto the squeezable wall.
