Claim 1
Independent Claim 237 words
A package for shallow depth articles comprising in combination: a. a single blank of paperboard or the like scored at each edge to form a substantially rectangularly shaped and centrally located back panel portion having abbreviated side and end closure flaps separated from the centrally located back panel portion by said score lines; and, b. a flattened tubular segment of transparent material having top and bottom walls and being dimensioned to substantially the same size as said back panel portion ; c. a first adhesive means on the inside of said blank and consisting of a plurality of substantially continuous zones of adhesive located adjacent the abbreviated side closure flaps and centrally of said centrally located back panel portion and securing the bottom wall of said tubular segment to said centrally located back panel portion ; d. a second adhesive means on the inside of said blank and consisting of substantially continuous zones of adhesive located on one abbreviated end closure flap and both abbreviated side closure flaps and securing the abbreviated end and side closure flaps around one end and both sides of said tubular segment and to the top wall of said tubular segment while leaving an open end of said tubular segment exposed; and, e. means at one end of said package for permitting access to the interior of the tubular segment after the package is filled and the remaining open end is closed.
