Abstract
The accompanying description and drawings disclose a liquid carrying paperboard carton having straw opening means formed in a side wall panel thereof. The straw opening means includes a tear strip formed by cuts through the carton wall beginning at the edge of the side panel adjacent the usual underlying fifth panel. 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. The formation of the tab automatically provides a cut-out portion on the edge of the side seam flap of the adjacent blank while being cut from a roll of paperboard, thus providing an opening for a straw hole when the tear strip of a completed container is peeled back from the underlying fifth panel.
