DETAILED DESCRIPTION

(7) While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.

(8) FIG. 1 shows a first stack of containers 10 in accordance with one aspect of the present invention, and a second stack of containers 12 in accordance with a modified aspect of the present invention. The containers 10 of the first stack are shown having an opening or window 14 in a front and a top portion of the container 10. The containers 12 of the second stack are shown having a detachable panel 16 in the front and top portions of the container 12. Upon removal of the detachable panel 16, the containers 12 of the second stack will appear similar or identical to the containers 10 of the first stack.

(9) As used herein, directional or positional terms (e.g., front, top, horizontal, etc.) are made with respect to the invention as shown and positioned in the drawings, and as typically set up. These terms are not meant to limit the invention to being in such positions (e.g., a “top” wall or portion described herein would still be a “top” wall even if one placed a container upside down).

(10) FIGS. 2A and 2B illustrate a blank 18 for forming the containers 10 shown in the first stack of FIG. 1. The blank 18 is cut from a sheet of material, such as paperboard, a plastic sheet, or a corrugated paper or corrugated plastic sheet (or other similar or suitable material).

(11) The blank 18 includes panels for a back wall 20, a first side wall 22, a front wall 24 and a second side wall 26. The panels are separated by fold lines.

(12) Each of the first and second side walls 22, 26 have matching top gable areas 28, 30, respectively. The gabled areas 28, 30 are formed from angled segments forming an upwardly directed point at a central location (e.g., an upside down “V” shape). Each side wall includes a first top edge segment that extends upward from one end of a top edge of the back wall and a second top edge segment that extends upward from one end of the top edge of the front wall. The segments meet at the central location to form the upside down “V” shape.

(13) Similarly, each of the first and second side walls 22, 26 include bottom gable areas 32, 34, respectively, having angled segments forming an upwardly directed point at a central location that match or mirror the top gable areas 28, 30. Each side wall includes a first bottom edge segment extending upward from one side of a bottom edge of the back wall, and second bottom edge segment extending upward from one end of a bottom edge of the front wall. This matching shape (between the top of the side walls and the bottom of the side walls) facilitates stacking two or more like containers.

(14) A top wall or side 36 is formed from a plurality of flaps extending upward from the back, first side, second side and front walls 20, 22, 24 and 26. These include a top flap 38 extending from the top edge of the back wall 20 and a corresponding top flap 40 extending from the top edge of the front wall 24. Each of the side walls 22, 26 include a first top flap 42, 44 (spanning one of the angled segments forming an upper edge of the gable area) and a second top flap 46, 48 (spanning another of the angled segments forming the upper edge of the gable area). The flaps extending from the side walls 22, 26 are folded under the flaps 38, 40 extending from the back and front walls 20, 24 when the container 10 is set up.

(15) Similar to the top side 36, a bottom wall or side 50 is formed from a plurality of flaps extending upward from the back, first side, second side and front walls 20, 22, 24 and 26. These include a bottom flap 52 extending from the bottom edge of the back wall 20 and a corresponding bottom flap 52 extending from the bottom edge of the front wall 24. Each of the side walls 22, 26 include a first bottom flap 56, 58 (spanning one of the angled segments forming a lower edge of the gable area) and a second bottom flap 60, 62 (spanning another of the angled segments forming the lower edge of the gable area). The flaps extending from the side walls 22, 26 are folded under the flaps 52, 54 extending from the back and front walls 20, 24 when the container 10 is set up. The bottom and top edges of the back wall 20 and the front wall 24 are generally horizontal when set up.

(16) The top flap 38 from the back wall 20 and the top flap 40 from the front wall 24 each include a locking flap 64, 66, that when folded, force tabs 68, 70 to extend upward from the container 10 when set up. The tabs 68, 70 are aligned and effectively form a single tab structure 72 (while each flap 64, 66 includes a tab 68, 70, in the example illustrated, a container can also be formed wherein only one of the top flaps 38, 40 includes structure for forming a tab).

(17) The bottom flap 52 from the back wall 20 and the bottom flap 54 from the front wall 24 each include a centrally located cut away portion 74, 76 that collectively form a slot 78 when the container 10 is set up. The slot 78 cooperates with the tab 72 of a like container 10 when stacking two or more like containers 10.

(18) FIGS. 2A and 2B also show the front window 16 which extends through a portion of the front wall 24 and a portion of the top flap 40 extending from the front wall 24. Other windows can be provided on the back wall and side walls as desired.

(19) Additionally, the blank 18 includes a glue panel 80 extending at one end of the blank 18 from the side of the second side wall 26. The glue panel 80 is glued to the edge of the back wall 20 at the other end of the blank 18 to initially begin forming the container 10.

(20) FIGS. 3-8 illustrate formation of the container 10 from the blank 18. As shown in FIG. 3, the glue panel 80 is glued to an inwardly facing surface of the back wall 20 to create a rectangular tube like shape having an open top and open bottom. FIG. 4 illustrates the top flaps 42, 44, 46, 48 and bottom flaps 56, 58, 60, 62 of the first and second side walls 22, 26 initially folded inward. This is followed in FIG. 5 with the bottom flaps 52, 54 of the back and front walls 20, 24 folded inward. The slot 78 is formed when the flaps 52, 54 are locked together. The bottom flaps 52, 54 include various tabs 82, in a zigzag pattern with intervening resting areas, extending from a bottom edge of the flaps to lock the flaps 52, 54 together.

(21) FIG. 6 shows the locking flaps 64, 66 connected to the top flaps 38, 40 folded downward. This forces tabs 68, 70 to extend upward. FIG. 7 shows the top flaps 38, 40 folded downward to form the top side of the container 10 with the upwardly extending tab 72 (formed from the tabs 68, 70). Two set up containers 10 are shown in FIG. 8.

(22) FIG. 9 shows four set up containers 10 stacked together on the right and three aligned containers 10 in an exploded view.

(23) Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
