Abstract
A vented automatic dispending cap for use with a flexible container may generally include a body and a retainer cap attached to the body. A pressure chamber is formed between the body and retainer cap. A set of resilient spring members spaced around the body holds the retainer cap against the body, which seats a valve within a dispensing hole extending through the cap. When the container is squeezed, product in the container may be forced into the pressure chamber expanding the pressure chamber and unseating the valve, thereby allowing product to exit the dispensing opening. A lip seal around the upper circumferential edge of the body prevents fluid from leaking out of the sides of the chamber but allows air to enter the chamber for venting the flexible container.
