ABSTRACT:
A container sealing system is disclosed herein for use in conjunction with a refillable container having a resealable closure member associated therewith. The sealing system includes a first fluid tight sealing member disposed between and engageable with the closure member and the container and a second sealing member integrally formed on the closure member and engageable with a portion of the container so as to prevent nongaseous contents of the container from leaking into the area of threaded engagement between the closure member and container. A vent passage is also provided in the closure member which is operative to provide safe controlled relief of pressure within the container in response to partial removal and prior to full removal of the closure member.
