  • Patent number: 6102237
    Abstract: Various embodiments of a sealing member disposed between a container body and an endpiece attached thereto are disclosed, as well as a method for disposing a sealing member between an endpiece and a container body. In one embodiment, a sealing member is disposed within a space between a container body flange and a corresponding portion of the sidewall of the container body, is disposed between a space between an endpiece flange and a corresponding portion of an endpiece wall, and is further disposed between the endpiece flange and container body flange. As such, the sealing member has a generally S-shaped configuration in cross-section. At least one and preferably two scores are incorporated on the sealing member to facilitate at least a partial removal of the endpiece from the container body so as to be able to access the contents of the container.

  • Patent number: 5875914
    Abstract: An open-ended container body is covered, preferably sealingly, by an endpiece/sealing-member. An annular flange of the endpiece/sealing-member is captured by crimping with a container body flange. The endpiece/sealing-member flange is coupled to the remainder of the endpiece/sealing-member by a tear strip which, upon removal, permits the remainder of the endpiece/sealing-member to be fully or partially removed from the open end of the container. The tearstrip is preferably integrally formed with the remainder of the endcap.
