ABSTRACT:
A container including a one-piece folded body. The container includes a central portion divided into a bottom section, a rear section and a top section. First and second foldable hinges extend across the central section, substantially parallel to each other. The first and second hinges separate the bottom section from the rear section and the rear section from the top section, respectively. A side section adjoins the central section and is foldable along a first foldable crease perpendicular to the first and second hinges. The first foldable crease separates the side section from a bottom side section, rear section from a rear side section and the top section from a top side section. A crease is formed in the rear side section. A crease is also formed in the top side section. The creases in the rear and top side sections are substantially parallel to each other. Upon movement from the open position to the closed position, the container reaches a critical position at which a spring action biases the container to the closed position.
