ABSTRACT:
A new carton blank uniquely scored and a method of folding for a liquid-tight flat top container is disclosed. The scoring pattern and tab configuration of the carton makes possible the formation of a modified gable top container the top of which is subsequently folded into the horizontal plane and held in that position leaving a flat top closure. The carbon blank is shaped and scored for folding into substantially a gable top container. An additional score line extending across one of the two roof panels and its associated triangular fold-in tabs facilitates the folding of the modified gable top into a horizontal (flat top) position. In the preferred embodiment the modified gable top, after folding, is held in its horizontal (flat top) position by a bond formed between an extension of one of the sealing tabs and one of the roof panels of the modified gable top. The sealing tab extension is attached to the remainder of the carton by a perforated section of the carton blank to allow one desiring to open the flat top container to tear along the perforation and fold the modified gable top into its pour spout position. In an alternative embodiment the bond holding the modified gable top in its horizontal position is created between a single conventional sealing tab and one of the roof panels of the modified gable top. In this second embodiment, one desiring to open the carton need only break the bond, and fold the modified gable top into its pour spout position.
