    • PROBLEM TO BE SOLVED: To provide a carton having a zipper which does not decrease strength of the carton, can surely propagate breakage along a weakened line, and can be broken from both directions. SOLUTION: The carton includes a plurality of panels including a bottom wall/a side wall/a top wall forming a cylindrical structure. The top wall panel includes the zipper, both sides of which are partitioned by a pair of breaking lines to be broken when the carton is opened. Each breaking line is formed by arranging a plurality of Z-shaped/reverse Z-shaped short slits in line, and two sides at both ends of the three sides with the Z-shaped/reverse Z-shaped short slits are extended toward the extending direction of each breaking line. Each breaking line has a pair of dispersing parts which are mutually dispersed and extended from its breaking starting point, a pair of parallel parts which are mutually parallel and extended near the terminal ends of the dispersing parts, and a pair of converging parts which mutually converge near the terminal end of the parallel parts to the breaking end points. The breaking starting point and the breaking end point are mutually in mirror-image relation with the dispersing part and the converging part, and the zipper can be opened from both sides of the breaking starting point and the breaking end point.

    • 要解决的问题:为了提供一种不会降低纸箱强度的拉链的纸箱,可以沿着弱化线确实地传播断裂,并且可以从两个方向断裂。 解决方案:纸箱包括多个面板,包括形成圆柱形结构的底壁/侧壁/顶壁。 顶壁板包括拉链,其两侧由打开纸箱的一对断开线分隔开,以便破碎。 每条断线通过排列多条Z形/反向的Z形短狭缝而形成,并且Z形/反向Z形短狭缝的三边两端的两侧向延伸方向延伸 每条断线的方向。 每个断线具有一对分散部分,其从其断裂起点相互分散和延伸,一对平行部分在分散部分的末端附近相互平行和延伸,并且一对会聚部分相互会聚 在平行部分的终端附近到断裂端点。 断裂起点和断裂端点与分散部和会聚部相互成镜像关系,并且拉链可以从断裂起点和断裂终点的两侧开口。 版权所有(C)2008,JPO&INPIT
