AUTOMATIC DISPENSING CAP FOR A SQUEEZEABLE BOTTLE

摘要

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.

1. An automatic dispensing cap for use with a container, the automatic dispensing cap comprising:
a body comprising a sealing lip and a protrusion, and a retainer cap connected to the body and having a chamber therein and a dispensing aperture in fluid communication with the chamber, wherein the retainer cap can move relative to the body between a closed position wherein the protrusion is seated in the dispensing aperture to prevent fluid flow through the dispensing aperture, and an open position wherein the protrusion is unseated from the dispensing aperture to allow fluid flow through the dispensing aperture, wherein the retainer cap is resiliently biased toward the closed position, and wherein the sealing lip is resiliently biased against the retainer cap and acts as a one-way valve to prevent fluid from exiting the chamber and to allow air to enter the chamber.
