Abstract: According to an embodiment, a container containing fluid fitted with a cap that contains a one-way valve that is placed on the upstream opening of a dispensing nozzle. Dispensed fluid is expressed by compressing the flexible walls of the container which serves to open the dispensing nozzle valve. An air recovery vent will be placed in the cap in order to allow the internal and external pressure to equalize after the contents have been partially dispensed. The vent may optionally be channeled up into the container away from the container terminus by use of a small extension tube. The exit of the vent hole/tube contains another one-way valve which prevents backflow of fluid and air while allowing air to enter the container. Thus, the flow of product out of the container and air into the container are both unidirectional.
