    摘要： A container for sliced meat products or the like has a base including a marginal base flange, a raised pedestal, and a short peripheral sidewall connecting the pedestal to the marginal base flange. A cover is also provided including a marginal cover flange and a cavity, the cavity being formed by a raised top wall and a long peripheral sidewall connecting the marginal cover flange to the top wall. A plurality of concave channels are provided along the interior surface of the long peripheral sidewall. These channels extend from the top wall and terminate at a height above the marginal cover flange which is greater than or equal to the height of the short peripheral sidewall of the base. A plurality of depressions or grooves are also provided in the upper surface of the pedestal. Preferably, the grooves extend substantially perpendicularly to the adjacent portion of the short peripheral sidewall and are equidistantly spaced. In addition, the end of each groove adjacent the short peripheral sidewall is matingly positioned adjacent a corresponding lower end of a respective concave channel.

    摘要： A continuous method of enclosing a proteinaceous product in a vacuumized and hermetically sealed package having a peelable hermetic reclosure and having a body member of semi-rigid preformed plastic with a first planar marginal portion and a central portion shaped to provide a packaging chamber. The package also has a flexible dimensionally stable base member having a corresponding second planar marginal portion and a central portion to provide a closure for said packaging chamber. The method requires placing a sufficient quantity of proteinaceous product in the central portion of the body member to substantially fill the central portion when the package is completed, positioning the first planar marginal portion face-to-face to the corresponding second planar marginal portion, vacuumizing the assembly, and hermetically sealing the package. The improvement is applying an adhesive to either the first planar marginal portion to provide at least a portion of the hermetic seal wherein said adhesive is a high molecular weight pressure sensitive hot melt adhesive having a viscosity of between 5,000 to 100,000 centipoise at 300.degree. F. and said adhesive provides a peelable hermetic reclosure.
