Abstract: A package is provided for enclosing a proteinaceous product under vacuumized and hermetically sealed conditions. The package has a peelable hermetic reclosure and 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 two planar marginal portions are adhered together face-to-face by an adhesive 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 about 5,000 and about 100,000 centipoise at 300.degree. F. and said adhesive provides a peelable hermetic reclosure.

Abstract: A reclosable package comprising interlocking closure strips positioned outside of a hermetic seal or seal area and the method for producing and filling same. The hermetic seal is of the easy-open or peelaway type so as to not destroy the integrity of the package or closure strips upon opening of the package.

Abstract: 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.

Abstract: This invention relates to packaging and is more particularly concerned with improvements in a package and method of forming the same in which the meat or perishable food package can be easily opened and reclosed while positively conveying a positive perception to the customer that the package is hermetically sealed before it is opened and that the package is positively resealable. An opening and reclosure cap provides an audible snap as it is opened and a similar audible snap as it is reclosed.

Abstract: 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.
