HYGIENIC PAPER CARTON WITH IMPROVED PULLING-OUT PROPERTIES

摘要

PROBLEM TO BE SOLVED: To provide a carton with improved pulling-out properties so as not to have occurrence of a paper tear or the like at pulling out a sheet of hygienic paper such as tissue paper. SOLUTION: A pair of curved and bending lines 17 protrusively formed into an approximate arch toward the center of a face provided with a pulling-out opening are provided by joining both ends of at least a pair of ridge lines composed of sides of the carton and the face of the pulling-out opening. Rising parts 18 surrounded by the curved and bending lines and a pair of the sides facing the lines are formed. Bending lines 19 are provided for pushing-in and extend in a carton height direction from the tops of the rising parts 18 to the bottom of the longer sides or the shorter sides of the carton adjoining the rising parts 18. When the bottom of the rising parts 18 or a carton side adjoining the rising parts 18 is pushed into the center of the carton, the face provided with the pulling-out opening is curved and deformed into an arch along the curved and bending lines and a space is formed between the upper end of a sheet of the paper housed inside the carton and the opening.
