Abstract:
1. A container for dispensing products of varying viscosity, the container comprising: a flexible body defining a cavity; a first cap coupled to a first end of the flexible body, the first cap comprising a first one-way valve configured to automatically open during use of the container to allow the product to exit from the cavity defined by the body and automatically close during use to substantially obstruct fluid and/or air from entering the cavity defined by the body; a second cap coupled to a second end of the body, the second cap comprising a second one-way valve configured to automatically open during use of the container to allow fluid and/or air to enter into the cavity defined by the body and automatically close during use to substantially obstruct fluid and/or air from exiting the cavity defined by the body; a first chamber positioned within the cavity defined by the body, the first chamber formed by a first flexible material having an outer diameter being smaller than an inner diameter of the flexible body, the first chamber enclosed in part by the first cap; a second chamber positioned within the cavity defined by the body, the second chamber formed by a second flexible material having an outer diameter being smaller than the inner diameter of the flexible body, the second chamber enclosed in part by the second cap; and a third chamber positioned within the cavity defined by the body, the third chamber defined by an inside surface of the flexible body, an outside surface of the first chamber and an outside surface of the second chamber; wherein a decrease in volume of the first chamber results in an inlet of air into the second chamber, which causes inflation of the second chamber when the flexible body recovers to a first shape after having been compressed to a second shape.
