MANUALLY OPENABLE SEALED OVERWRAP AND TRAY

摘要

The present invention relates to improved manually openable packages which include a rigid or semi-rigid tray having a single thermoplastic overwrap comprising a polymeric laminate surrounding the tray and having a front panel and an opposing back panel. The inventive packages also include a continuous seal circumscribing a recessed cavity of the tray which comprises a heat seal formed by heat sealing a portion of the front panel to the peripheral flange of the tray.

主权项

1. A manually openable package comprising:
a rigid or semi-rigid tray having a base and at least one sidewall extending from said base thereby forming a recessed cavity; wherein said at least one sidewall comprises a peripheral flange extending generally perpendicularly from said at least one sidewall and circumscribing said recessed cavity; a single thermoplastic overwrap surrounding said tray and comprising a polymeric laminate; wherein said overwrap comprises a front panel and an opposing back panel comprising a longitudinal seal, a first leading end seal positioned substantially transverse to said longitudinal seal, an opposing second trailing end seal positioned substantially transverse to said longitudinal seal; a continuous seal circumscribing said recessed cavity and comprising an inner perimeter defined by a heat seal formed by heat sealing a portion of said front panel to said peripheral flange; and a removable portion of said front panel having an outer periphery inside said inner perimeter of said seal and defined by a line of weakness in said polymeric laminate.
