Abstract

A non-spill beverage container includes a cap having a tube-like spout and a baffle mounted inside the spout, and a flow control member having a spout (first) membrane supported over the spout opening. A vent (second) membrane that is disposed adjacent to the spout and is supported over a vent opening defined in the cap. The spout and vent membranes are punctured to form multiple, substantially round pinholes that remain closed to prevent fluid flow under normal atmospheric conditions, and open to facilitate fluid flow under an applied pressure differential (e.g., when sucked on by a child). The baffle limits the differential pressure applied to the spout membrane when the container is not in use. The flow control member can only be removed from the cap by removing the cap from the container body and pressing a flexible safety button from an inside surface of the cap.

Description

RELATED APPLICATIONS

[0001] This application is a continuation-in-part of U.S. Patent application for “NON-SPILL CONTAINER WITH FLOW CONTROL STRUCTURE INCLUDING BAFFLE AND ELASTIC MEMBRANE HAVING NORMALLY-CLOSED PINHOLES”, U.S. application Ser. No. 11 / 131,721, filed May 17, 2005.FIELD OF THE INVENTION

[0002] The present invention relates to fluid flow control devices for beverage containers, and more specifically it relates to elastic flow control members for, e.g., child sippy cups, and adult “travel” mugs and sports bottles. RELATED ART

[0003] Sippy cups, travel mugs and sports bottles represent three types of beverage containers that utilize flow control devices to control the ingestion of beverage in response to an applied sucking force. Sippy cups are a type of spill-resistant container typically made for children that include a cup body and a screw-on or snap-on lid having a drinking spout molded thereon. An inexpensive flow control element, such as a soft rubber or silicone o...
