Abstract

An end loaded top opening carton is formed from a unitary cut and scored blank of paperboard, and is folded to define integral body and cover portions having single-ply top and bottom walls and double-ply front, rear and end walls. The rear wall includes an inner panel folded from said body portion wall and an outer panel formed from said cover portion, there being an intermediate panel hinged to the rear wall inner panel and the rear wall outer panel. The front and end walls each include an inner portion folded from said body portion and an outer portion folded from said cover portion. The front and end walls are separable into upper and lower sections, so that when the carton is opened, upper portions of the front, end and rear inner panels project above the lower sections of the front and end outer panels to form a collar for the articles, the collar being telescopically received within the front, end and rear outer panel upper sections.

Claims

1. In an end loading, top opening carton for holding packaged articles, said carton being formed from a unitary blank of foldable paperboard, and having integral body and cover portions and single-ply top and bottom walls and inner and outer ply front, rear, and end walls, the combination of:
