Abstract

A gable top carton and a blank for forming it. The upstanding fin at the top of the gable includes two fin forming protions or extensions from each gable panel laminated together. Half of the length of each fin forming gable panel portion is provided with a horizontally extending tear line and also with a plurality of vertically extending cut lines at its midportion, the latter functioning as tear lines. To open the carton, the midportion of the upper edge of the fin is ripped downwardly and thereafter half of the fin removed by also tearing along the horizontal tear lines, to thus open half of the carton top for manual pour spout formation by the consumer. By virtue of the plurality of vertical cut lines on each gable panel fin portion, the initial vertical ripping can take place along respective non-corresponding (non-homologous) vertical cut lines in each of the two fin forming gable portions, thus compensating for any edgewise misalignment of the gable panel fin portions. The carton interior is internally coated with a barrier layer material, as conventional, but the several cuts through the paperboard and the external PE coating do not extend through the barrier layer, thus preserving the contamination inhibiting property of the barrier layer.
