Abstract

A low profile inflation valve intended to be installed with an article to inflated with air, water or other fluid. The valve of the invention comprises a valve body which is sealed, such as by an adhesive, heat-sealing or RF sealing, to a corresponding opening in the article to be inflated. The body comprises a generally circular cylindrical configuration with internal threads for receiving a cap. The cap correspondingly comprises a circular cylindrical configuration having exterior threads for threaded engagement into the valve body. A flapper is affixed to the underside of the cap and functions as a one-way valve to prevent fluid from within the article from escaping therefrom when the cap is partially threaded within the body and yet which allows inflation of the article. Moreover, full tightening of the cap within the body sealingly entraps the flapper between the cap in a lower portion of the body so as to create an airtight seal and prevent further inflation (or deflation) of the article. A dust cap is provided for covering the cap during use of the article after inflation so as to prevent dust and other debris from contaminating the interior of the cap and otherwise obstructing or interfering with the proper sealing of the flapper to the underside of the cap. Preferably, the dust cap is tethered to the cap by means of a tether having a living hinge and the cap is tethered to the body by means of another tether which allows the cap to be fully removed from the body and moved off to the side during deflation of the article.
