ABSTRACT:
A carton or package for packaging semi-fluid material which can be hardened by freezing, such as ice cream, sherbet and the like, is formed from specially constructed integral carton blank and a special process for assembling the same. The carton blank has a front panel, a bottom panel, a rear panel, a cover panel, and a front cover sealing flap articulated one to the other in the order named with end-forming flaps and glue-flap extensions extending laterally therefrom adapted to be glued together to form inner and outer walls and side-cover flaps. The bottom outer wall-forming flap is glued to the inner wall-forming flaps by glue strips along the side edges of the latter, where they are joined to the front and rear panels, and the side-cover flap has a tuck-in tab adapted to be tucked in under the bottom outer wall-forming flap between the glue strips. The glue-flap extensions are adapted to fold over the side-cover flaps and to be glued thereto by an extension of the glue strip adjacent the front of the carton. In forming the carton or package, one end is closed first by folding in the side flap extensions, folding down the side-cover flap, applying the glue strips with the one adjacent the front of the carton extending up over the folded-down side-cover flap, then folding up the bottom outer wall-forming flap to a position overlying the tuck-in tab and folding in the glue-flap extensions over the glue strip on the side-cover flap and causing adherence between the glue and the folded-in flaps. The tube thus formed is then filled and the other end closed in a like manner.
