The device 20 may be attached to the bottom 10 by staples, glue, or other attachment devices or fasteners not shown. The entire receptacle 1 may be made of a biodegradable material. The entire receptacle may be made of paper, cardboard, stiff cardboard, or any rigid biodegradable material which can be folded from the flattened state of FIG. 6, where sides 2, 4, 6, and 8 are parallel or substantially parallel to the bottom 10, and sections 4a and 4c are parallel or substantially parallel to the section 4b, and sections 8a and 8c are parallel or substantially parallel to the section 8b, to the upright state of FIG. 1, where sides 2, 4, 6, and 8 are perpendicular or substantially perpendicular to the bottom 10, and sections 4a and 4c are perpendicular or substantially perpendicular to the central section 4b and sections 8a and 8c are perpendicular to substantially perpendicular to the central section 8b. The sections or panels 4a and 4c may be stapled to the sides 6 and 2 respectively, or otherwise attached, such as by gluing, to fix the panel or side 4 in the upright and assembled state shown in FIG. 1. Similarly, the sections or panels 8a and 8c may be stapled to the sides 6 and 2 respectively, or otherwise attached, such as by gluing, to fix the panel or side 8 in the upright and assembled state shown in FIG. 1.
The bottom 10 may have circular or substantially circular openings 10b, 10c, 10d, and 10e, as shown in FIGS. 4, 5, and 7.
FIG. 10A shows a top, front, right perspective view of the receptacle 1, with the receptacle 1 shown in an upright assembled state, and a top, front, right perspective view of an additional receptacle 100, which may be identical to the receptacle 1 of FIG. 1, with the additional receptacle 100 shown in an upright assembled state. FIG. 10B shows a top, front right perspective view of the receptacle 1, stacked on top of the additional receptacle 100.
FIG. 11A shows a front view of the receptacle 1 and a front view of the additional receptacle 100, with the receptacle 1 and the additional receptacle 100 shown in an assembled upright state. FIG. 11B shows a front view of the receptacle 1 stacked on top of the additional receptacle 100, with the receptacle 1 and the additional receptacle 100 shown in an assembled upright state.
FIG. 12A shows a right side view of the receptacle 1 and a right side view of the additional receptacle 100, with the receptacle 1 and the additional receptacle 100 shown in an assembled upright state. FIG. 12B shows a right side view of the receptacle 1 stacked on top of the additional receptacle 100, with the receptacle 1 and the additional receptacle 100 shown in an assembled upright state.
The additional receptacle 100 includes sides 102, 104, 106, and 108, similar or identical to sides 2, 4, 6, and 8 of the receptacle 1. The side 104 includes sections 104a-c similar or identical to sections 4a-c. The side 108 includes sections 108a-c similar or identical to sections 8a-c. The receptacle 100 includes device 120 having walls 120a and 120b, similar or identical to device 20 having walls 20a and 20b. The receptacle 100 includes handles, similar or identical to handles 3, 5, 7, and 9, including handles 107 and 109 shown in FIGS. 11A and 12A, respectively.
When the receptacle 1 is stacked on top of the receptacle 100, as in FIGS. 10B, 11B, and 12B, the outer peripheral wall 20a (shown in FIG. 5) of the receptacle 1 sits on the top edge 104d (corresponds to 4d shown in FIG. 4) of panel or section 104b (shown in FIG. 10A), on the top edge 102a (corresponds to 2a shown in FIG. 4) of panel 102 (shown in FIG. 10A), on the top edge 106a (corresponds to 6a shown in FIG. 4) of panel 106 (shown in FIG. 10A), and on the top edge 108d (corresponds to 8d shown in FIG. 4) of panel or section 108 of the receptacle 100. While the outer peripheral wall 20a sits on edges 104d, 102a, 106a, and 108d, the inner peripheral wall 20b is nested inside of the chamber 101a (corresponds to chamber 1a shown in FIG. 4) of the receptacle 100, such that the inner peripheral wall 20b is surrounded by section 104b, side 102, side 106, and section 108b shown in FIG. 10A. This nesting arrangement, prevents the receptacle 1 from moving laterally, such as in the directions D1 or D2 shown in FIG. 11B, when the receptacle 1 is stacked and nested on top of the receptacle 100 as in FIGS. 11B and 12B. In FIGS. 11B and 12B, the location of the inner peripheral wall 20b is shown by a dashed lines because the inner peripheral wall 20b is typically not visible when it is nested inside of the receptacle 100.
The inner wall 20b may have a length L1, shown in FIG. 11B, which may be seventeen and five eighths inches and a width W1, shown in FIG. 12B, which may be eleven and five eighths inches. The outer wall 20a may have a length L2, shown in FIG. 11B, which may be eighteen inches and a width W2, shown in FIG. 12B, which may be twelve inches. Other sizes may be used but these sizes are particularly useful for a twenty four quart milk case.
The receptacle 1 is particularly useful in the dairy industry for carrying quarts or other containers of milk.
Each of the panels or sides 2, 4, 6, and 8 may have a height of H1, shown in FIG. 2 and FIG. 3, which may be about eleven inches. The outer wall 20a of the device 20 may have a height H2, shown in FIG. 2 and FIG. 3, which may be about three thirty-seconds ( 3/32) of an inch. The inner wall 20b of the device 20 may have a height H3, shown in FIG. 2 and FIG. 3, which may be about three eighths (3⁄8) of an inch. The height, H3, of the inner wall 20b is configured so that it is sufficient to provide a nesting feature when the receptacle 1 is stacked on top of the receptacle 100 as in FIGS. 11B and 12B, but not too large so that the inner wall 20b does not contact beverage containers, such as milk cartons 200, shown by dashed lines in FIG. 12B, placed in chamber 101a (shown in FIG. 10A) of the receptacle 100. In FIG. 12B the milk cartons 200 include milk carton 202, 204, and 206 shown by dashed lines. The milk cartons 200 would include further milk cartons not shown in the direction of the length L1 of FIG. 11B, so that there would typically be a plurality of rows in the direction of length L1 of FIG. 11B of milk cartons or other beverage containers, and a plurality of columns of milk cartons or other beverage containers in the direction of width W1 of FIG. 12B. The receptacle 1 and the milk cartons 200 or other beverage containers are configured so that the inner wall 20b does not contact the top of milk cartons 202, 204, and 206 and the inner wall 20b does not contact other milk cartons which are not shown. In at least one embodiment the receptacle 1 is configured so that a matrix of milk cartons, fits snugly, upright, inside of the chamber 1a of the receptacle 1 or chamber 101a of the receptacle 100, when the cartons 200 are standing upright as in FIG. 12B.
The receptacle 1 may be made of a moisture absorbing material to absorb moisture that may leak or spill out of beverage containers, such as milk cartons. The receptacle 1, including the device 20 may be disposable.
Although the invention has been described by reference to particular illustrative embodiments thereof, many changes and modifications of the invention may become apparent to those skilled in the art without departing from the spirit and scope of the invention. It is therefore intended to include within this patent all such changes and modifications as may reasonably and properly be included within the scope of the present invention's contribution to the art.
