Patent number: 8915234Abstract: A cap assembly includes a body and a tether. The body is configured to be fastened to a container for closing an opening in the container. An aperture is formed in the body, and the tether has a fastener, where a portion of the fastener extends through the aperture in the body. A gap is formed between the portion of the fastener and the body that allows for venting of vapors from the container around the portion of the fastener that is extending through the aperture.Type: GrantFiled: October 25, 2010Date of Patent: December 23, 2014Assignee: Briggs & Stratton CorporationInventors: John Gulke, Christy L.
