Abstract
Abstract A marketing package for fragile, icing coated bakery items is provided, comprising a paperboard base having a horizontal configuration conforming to that of the item to be packaged but extending horizontally beyond the edges of the item. A transparent plastic cover is provided having a top wall of the same configuration of the item to be packaged but of greater horizontal dimensions than the item and lesser dimensions than that of the paperboard base. An integral depending sidewall is peripherally attached to the top wall of the cover and the bottom edges of the sidewall are formed into a horizontal flange which rests on the perimeter of the paperboard base. Projecting tabs are peripherally spaced on the paperboard base and a score line is provided in the paperboard to permit such tabs to be readily deflected downwardly. At the same location, an integral horizontally projecting tab is provided on the bottom wall of the plastic cover to lie in overlying relationship to the paperboard tab, however, the plastic tab is substantially rigid relative to vertical displacement. A food grade tacky adhesive secures the overlying plastic cover tabs and base plate tabs and the plastic cover may be readily removed from the base plate by deflecting the base plate tabs downwardly to effect the shearing of the tacky adhesive.
