  • Container
    Patent number: 4125632
    Abstract: A plastic body is provided for use in a container which is adapted to hold product under vacuum, without undesirable deformation of the container. The body has a curvilinear bulge at the base of its cylindrical sidewall, and the bulge is dimensioned and configured to permit its slight deflection under vacuum which, in turn, facilitates upward movement of the bottom wall of the body. These changes effect a reduction of volume within the body, thereby reducing the level of vacuum which forms therewithin. The characteristics of the body render it particularly well-suited for production in relatively small sizes, utilizing relatively rigid synthetic resinous materials. It is also especially adapted for use in connection with a metal end closure, which may be hermetically sealed thereonto.
