Abstract
Abstract A collapsible container is disclosed in which the container is cut from a single blank. The blank may be folded so as to form an angled front panel together with an open front area for entrance into and out of the container. Cooperative locking means formed in the blank permit relative locking and holding of the respective panels when the container is in the opened or assembled condition. The end opposite the open front area is suitably closed.
