Abstract

A hexagonal paperboard container, which comprises:

(a) a one-piece, upstanding, generally tubular, reinforcing member consisting of six, foldably connected, substantially rectangular, upstanding, reinforcing panels;

(b) a one-piece body member having two sets of three, substantially rectangular, foldably connected, upstanding side wall panels and a bottom wall foldably connected along its opposite sides to the central side wall panel of each set of side wall panels;

(c) the sets of side wall panels being located on opposite sides of the tubular reinforcing member and the side wall panels being bonded to the reinforcing panels;

(d) two of said reinforcing panels which are bonded to the central side wall panels having abutting major flaps foldably connected thereto at the bottom edges thereof;

(e) the four remaining reinforcing panels having minor flaps foldably connected thereto at the bottom edges thereof;

(f) said major and minor flaps extending substantially horizontally and fitting together to form a bottom wall for the reinforcing member which lies above the bottom wall of the body member whereby a double-thickness container bottom wall is formed.

Claims

1. A hexagonal paperboard container, which comprises:

(a) a one-piece, upstanding, generally tubular, reinforcing member consisting of six, foldably connected, substantially rectangular, upstanding, reinforcing panels;

(b) a one-piece body member having two sets of three, substantially rectangular, foldably connected, upstanding side wall panels and a bottom wall foldably connected along its opposite sides to the central side wall panel of each set of side wall panels;

(c) the sets of side wall panels being located on opposite sides of the tubular reinforcing member and the side wall panels being bonded to the reinforcing panels;

(d) two of said reinforcing panels which are bonded to the central side wall panels having abutting major flaps foldably connected thereto at the bottom edges thereof;

(e) the four remaining reinforcing panels having minor flaps foldably connected thereto at the bottom edges thereof;

(f) said major and minor flaps extending substantially horizontally and interengaging and fitting together non-overlappingly to form an integral, coplanar, unsecured bottom wall for the reinforcing member which lies above and completely covers the bottom wall of the body member whereby a double-thickness container bottom wall is formed.

2. The container in accordance with claim 1 wherein the two major flaps are concave trapezoids in configuration.

3. The container in accordance with claim 2 wherein two of the minor flaps are parabolic in configuration and the other two minor flaps are crescents in configuration.

4. The container in accordance with claim 3 wherein the parabolic flaps are disposed on either side of one of the concave trapezoidal flaps and the crescent flaps are located on either side of the other concave trapezoidal flap.

5. The container in accordance with claim 1 and including a pair of top closure sections comprising a horizontally extending trapezoidal panel foldably connected to each of said central side wall panels, each trapezoidal panel overlying pairs of substantially horizontally extending triangular panels which are foldably connected to the end side wall panels, and a downwardly extending closure flap foldably connected to each trapezoidal panel.

6. The container in accordance with claim 1 and including pairs of bottom flanges foldably connected to the bottom wall of said body member and secured to said side wall panels.
