ABSTRACT:
A single service container having a hollow body and a cap with a portion extending interiorly of the body. The cap is mounted to seal a wide mouth style of opening formed at the upper end of the body. Interiorly of the mouth, a portion of the cap extends downwardly so as to cooperate with the positive internal pressure of the container and assist in sealing the cap on the body. A conical ring is formed on the periphery of the dome and engages an undercut interior surface adjacent to the mouth. The container further includes means for sealingly engaging the perimeter of the mouth. To open the container, a pulling member is pulled thereby severing the sealing engagements between the cap and the mouth, releasing the internal pressure and opening the container.
