Abstract: A container end is provided so that upon opening, a generally triangular vent region is formed with an apex pointing rearwardly toward the head space to vent the container, e.g. during pouring. A container is provided that achieves a fast and smooth pour with a relatively small increase (relative to certain previous configurations) in the opening area and achieves a superior pour without increased bursting, buckling or opening failures associated with relatively larger openings.

Abstract: A method and apparatus for reshaping a container body (e.g., a metal, drawn and ironed container body) utilizing a floating mechanism for imparting an axial load is disclosed. In one embodiment, a container may have a substantially cylindrical sidewall with an inner surface and outer surface, where a shape defining means has a contoured surface positionable with respect to a container sidewall. When a floating mechanism imparts an axial load, a fluid seal is maintained allowing sidewall deformation by means of a directed pressurized fluid.

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.

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.

Abstract: A container (e.g., drawn and ironed) with modified end constructions is disclosed. In one embodiment, the end piece which is seamed onto the sidewall of the container body includes a push-down tab for opening the container. This tab includes at least one engagement section which is offset in relation to the center of the push-down tab and which is for interfacing with the consumer's finger (e.g., thumb) in a manner which facilitates a more effective opening of the push-down tab. The engagement section curves upwardly progressing toward the perimeter of the tab and therefore may be characterized as a generally ramped surface. In one embodiment, two such engagement sections are utilized and ramp upwardly in generally opposite directions. The integral end of the container body also includes a multi-stage center panel or dome for allowing stacking of filled containers.
