<p>PURPOSE:To enable an easy opening and closing of a shake-out opening by one hand by a method wherein a slide panel at an upper part of a front side in a wide-sided panel is slided in the lateral direction, so that an upper part of a narrow-sided panel may be projected to be V-shaped. CONSTITUTION:A folding area 4a is defined by a slantwise folding line (n) in an upper part of a narrow-sided panel 4, and a cutin (r) is formed in a wide- sided panel 1 which connects a middle part (beta) of an upper side of the panel 1 and a lower end (alpha) of the folding line (n). A slide panel 14 having an arched end edge, whose arch is drawn around the lower end (alpha) of the folding line (n) and has a radius as long as or a little shorter than the length of a straight line between the lower end (alpha) and the upper end (beta) of the cutin (r), is connected to a longer side edge of the folding area 4a, and this slide panel 14 is inserted into the cutin (r) from outside. An exposed part of the slide panel 14 is slided in the horizontal direction by a thumb of a hand which holds a carton, so that the folding area 4a is folded outwardly along the folding line (n) to form a V-shaped shake-out opening. After content is shaken out, a projected part is pushed in from the sideway by the thumb.</p> |
