Abstract

See full text

A clamshell type container is formed from a unitary blank (10) of paperboard, the top or crown of the container including two side wall panels (32) which extend slantingly downwardly and whose free edges extend beneath the upper edges of the lower container half side walls. The crown has a front wall formed of two panels (40, 48) folded together so as to define a dual layer front wall. The outer panel (40) of the dual layer front wall is provided with spaced apart perforated lines (46) to define a tear strip (44). The inner panel (48) of the dual layer front wall is provided with indicia to show the winning of a prize upon tearing off of the tear strip. Alternatively, the normally hidden inner surface of the tear strip may be provided with indicia. Either of the downwardly sloping side wall panels (32) of the crown or top may, alternatively, be provided with this tear strip and indicia construction. As a further variant, the auxiliary indicia panel (48) may be folded over the crown front panel (40) so that the auxiliary indicia panel (48) is on the outside of the dual layer (40, 48) crown front wall, instead of on the inside.
