摘要： A self-locking, reusable carton is formed from a unitary blank of paperboard. The carton and blank have self-locking end closure flaps which are hingedly coupled to adjacent end edges of the side panels of the carton. The closure flaps include two flaps with L-shaped slits formed therein and a locking flap free of fold lines with a locking tab at the free end thereof. During assembly the locking flap is forced downwardly to place the locking tab in the L-shaped slits to lock the carton in its fully assembled configuration.
摘要翻译：自锁，可重复使用的纸箱由纸板的整体坯料形成。纸箱和坯料具有自锁端盖，其铰接地联接到纸箱的侧板的相邻端边缘。闭合片包括两个形成在其中的L形狭缝的折片和一个没有折叠线的锁定片，在其自由端具有锁定片。在组装过程中，锁定挡片被向下推动以将锁定片放置在L形狭缝中，以将纸箱锁定在其完全组装的构型中。
