Publication number: 20110163108Abstract: A container venting disc is punctuated with gaps around the periphery to allow gases from the interior of the container to vent. An intermediate ridge or layer that abuts or is proximal to the interior edge of the container lip is implemented to prevent the disc from significantly moving laterally and to also center the venting disc within the container mouth. The gap(s) forms a channel in the disc to allow gases to escape between the edge of the container mouth and the container cap. The simplicity of design allows for easy manufacture and simple placement in a container, such as for a jar or bottle.Type: ApplicationFiled: January 7, 2010Publication date: July 7, 2011Applicant: STIEFEL LABORATORIES, INC.Inventor: Steven G.
