Abstract
Abstract A paperboard blank for a flip-top container, a flip-top container and a method of assembly are disclosed. The containers feature an initially sealed flip-top separable along perforations accessibly disposed on the front panel of the container. When opened, the flip-top exposes an access cutout of an integral internal collar which increases the structural strength of the container at certain critical locations. Each side of the container is provided with a latch having mating portions which are detachably connected and thus positively aligned during all of the container assembly steps to eliminate registry problems between the mating portions of the latches.
