ABSTRACT:
An improved display carton. The carton of the invention includes a front panel having lines of weakness extending from the top corners of the panel down to the scoreline defining the bottom of the front panel. Lines of weakness are also provided in one or more of the flaps defining the top of the carton. The flaps on the top of the carton do not completely close the carton so that a user may grasp the carton at the top and pull on the top panel to remove portions of the top and front panels and reveal the product within the case. A particularly advantageous feature of the invention,is the use of a cut in a scoreline to improve the compressive strength of the carton. The cut is made at the bottom of one or more columns of flutes at a point where the flute would otherwise bend due to the presence of a scoreline defining a fold. The cut causes a complete cut of the flute rather than folding; the complete cut results in an increase in compressive strength when compared to the folded flute. Advantageously, the cut is made at the bottom scoreline of the front panel at the points where the lines of weakness meet the bottom scoreline.
