Abstract: A container made from corrugated paperboard has a bottom wall, opposite side and end walls, and a self locking arrangement on the end walls holding the container in erected condition. The self locking arrangement includes first and second end panels on opposite ends of the side walls, and a third end panel on opposite ends of the bottom wall. The end panels form the end walls of the container. The first and second end panels have at least one notch formed in an upper edge, and a roll over flap is foldably joined by at least one web to an upper edge of each of the third end panels and is folded inwardly and downwardly over the upper edges of the first and second end panels into a locked position to hold the end panels and thus the container in erected condition. In the locked position, the web is engaged in the notch. In particular, the web has a thickness less than the thickness of an end panel, so that it fits deeply into the notch, producing a tight fit and reliable interlocking of the components of the self locking arrangement.

Abstract translation: 由瓦楞纸板制成的容器具有底壁，相对侧壁和端壁，以及在竖立状态下容纳该容器的端壁上的自锁装置。 自锁装置包括在侧壁的相对端上的第一和第二端板，以及在底壁的相对端上的第三端板。 端板形成容器的端壁。 第一和第二端板具有形成在上边缘中的至少一个切口，并且卷绕翼片通过至少一个腹板可折叠地连接到每个第三端板的上边缘，并且向内和向下折叠在上部 第一和第二端板的边缘进入锁定位置以保持端板，因此容器处于竖立状态。 在锁定位置，卷筒纸啮合在凹口中。 特别地，腹板具有小于端板厚度的厚度，使得其紧密地配合到凹口中，从而产生紧密配合并且可自动锁紧装置的部件的可靠互锁。
