Carton with lid sealed to tray end flanges and lid flaps sealed to tray

Abstract

A carton package comprising a plurality of blanks of carton material cut and scored so as to provide one or more tray compartments and a separate lid part. The lid part includes a lid panel having a pair of opposed end edges defined by a pair of opposed parallel free marginal edge portions extending along the top of a pair of opposed ends of the package and a pair of opposed side edges defined by a pair of opposed parallel lid flap panel fold lines integral with a pair of lid flap panels folded downwardly along the lid flap panel fold lines in generally perpendicular relation to the lid panel so as to define substantially the entirety of a pair of opposed sides of the package. The lid panel extends over the open top space provided by the one or more tray compartments which present (1) side wall panels disposed along the pair of opposed package ends having integral flanges extending outwardly from the outer edges thereof and constituting end defining side wall panels and (2) side wall panels extending along the pair of opposed package sides constituting side defining side wall panels. The interior surface of the flanges and the interior surfaces of the lid panel free marginal edge portions are sealed together in pressurized abutting relation with heat activated adhesive therebetween. The exterior surfaces of the side defining side wall panels and the interior surfaces of the lid flap panels are sealed together in contact abutting relation with heat activated adhesive therebetween.
