Abstract: The purpose of the present invention is to prevent or minimize the damage to a carton caused by sudden impact. This damage results most often from the cartons being dropped from some height. The type of carton damage is usually corner fracture. The tensile forces applied to the corner as the carton hits causes a tear to form at the base of the vertical score line (12) where the carton folds to make the bottom corner. A single score line (21) is formed in and at the side of the side panel (11) of a carton. Each score line extends outwardly from each side of the side vertical score lines which define the side panels of the carton. The purpose of these score lines is to induce a fold to form preferentially at the intersection of the score line and the vertical score line and away from the carton bottom corner when the carton is dropped or suddenly shocked. Each of the score lines should be long enough and placed a distance from the bottom wall to induce the fold line to form preferentially away from the bottom corner.

Abstract translation: 本发明旨在防止或最小化由突然撞击造成的纸板箱的变质。 这种恶化通常是由于一定高度的纸箱掉落造成的。 纸板箱的劣化类型通常是在角落中的一个突破。 当纸板箱受到冲击时，楔子受到的拉力在垂直引导线（12）的底部处引起撕裂，纸板折叠形成底部的拐角。 单侧定位线（21）形成在侧板（11）中和纸箱侧上。 每条标记线在限定纸板盒侧板的横向竖直标记线的两侧向外延伸。 这些准则的目的是促成折叠的形成，优选在引导线和所述垂直引导线的交叉处，并且远离盒子的底部的角落。 在硬纸板中，当纸板跌落或突然震惊时。 每条参考线必须相当长并且放置在离底壁一定距离处，以便形成优选与底角相对的引线。
