ABSTRACT:
The accompanying description and drawings disclose a method of forming a paperboard blank for a gable top type liquid carrying paperboard carton having straw opening means formed in a side panel of the gable top closure structure. The straw opening means includes a tear strip formed by cuts at least halfway through the carton wall beginning at the score line formed at the edge of the side panel adjacent the usual underlying side seam flap. In an alternate embodiment wherein the side seam flap is formed on the reverse end of the carton blank, a tab is formed from material available from the adjacent blank during the scoring and cutting process, and serves as an extension of the tear strip beyond the edge of the gable top side panel.
