Description

BACKGROUND

Technical Field

The present invention relates to stabilizers for milk crates, especially milk crates stacked on pallets.

Background of the Invention

Milk crates are generally cubical containers with a floor, four sidewalls extending from the floor and defining an interior, and an open top. Traditionally, milk crates are comprised of rigid plastic and stacked on pallets in a 3 by 3 matrix (3 high by 3 across), with nine total milk crates in each row on the pallet. Such crates, however, are prone to tipping.

Canadian Patent Application No. 2,163,675 (the '675 Application) teaches a device with pegs that attaches to the rim of a crate. The crates are shown in the '675 Application, as single stacked, and the device is meant to be used on the bottom crate. The device of the '675 Application is not designed to prevent the top-most crates from tipping.

U.S. Pat. No. 3,146,505 (the '505 Patent) teaches a stacklip that extends into and attaches the corners of four adjacent cartons. The stacklips of the '505 Patent are not attached and thus the device would be cumbersome to use. The cartons of the '505 Patent are cardboard and the stacklips of the '505 Patent have specially designed ledges (denoted therein by numeral 96) that bite into the cardboard. The lower end of the legs (denoted by 56) are splayed outwardly at 58. It appears that the system of the '505 Patent would be cumbersome to use and is not designed for use with rigid plastic milk crates.

Therefore, there is a need for stabilizers that are designed for use with milk crates stacked on pallets that prevent the crates for tipping.

DETAILED DESCRIPTION

With reference to FIGS. 1-10 the present invention provides a milk crate stabilizer system, designated by the numeral 10. In the drawings, not all reference numbers are included in each drawing for the sake of clarity. In addition, although other dimensions are possible, FIGS. 1-10 are CAD drawings, drawn to scale.

Referring to FIGS. 1-10, the milk crate stabilizer system 10 may include at least one row 12 of milk crates 14, each milk crate 14 comprising a floor 16, four sidewalls 18 extending from the floor 16 and defining an interior 20, and an open top 22. The milk crates 14 are preferably stacked on a pallet 54. The milk crates 14 are preferably comprised of a rigid plastic and cubical in shape. The floors 16 and sidewalls 18 may include holes in a lattice-type pattern, as depicted in FIGS. 1, 2 and 10, for example. Milk crates such as these are commonly known. In each vertical stack, the milk crates 14 are preferably partially nested inside each other.

The present disclosure provides a milk crate stabilizer 24 for use with such milk crates 14, particularly those stacked on a pallet 54 in columns of nine milk crates 14 per row 12, as depicted in FIGS. 1 and 2, for example. The milk crate stabilizer 24 may include a plate 26 located above the at least one row 12 of milk crates 14, and a plurality of groups 28 (preferably four groups) of four pegs 30 extending downwardly from the plate 26, and the pegs 30 contact the sidewalls 18 of adjacent milk crates 14 and removably join the adjacent milk crates 14, as best seen in FIGS. 1, 2 and 10. The milk crate stabilizer 24 may be formed of any material but is preferably rigid and comprised of, for example, plastic or wood. Preferably, at least the pegs 30 are rigid.

In some embodiments, each peg 30 comprises a top end 32 extending from the plate 26, a free bottom end 34, a height 36 extending from the top end 32 to the bottom end 34, and a width 38 generally perpendicular to the height 36 and the peg width 38 is less at the bottom end 34 of the peg 30 compared to the top end 32. In other words, preferably, the pegs 30 are tapered as best seen in FIGS. 3-7 and 9. Optionally, the pegs 30 are tapered cylinders, as best seen in FIGS. 3-10. Optionally, the peg heights 36 of the pegs 30 are identical and are, for example, about 2.75 inches. Optionally, the plate 26 is generally rectangular in shape and comprises a plate width 40 and a plate length 42 perpendicular to the plate width 40. Optionally, two pegs 30 in each group 28 are aligned along the plate width 40 and two pegs 30 in each group 28 are aligned along the plate length 42, as best seen in FIGS. 6 and 8. Preferably, the pegs 30 in each group 28 are arranged in a rectangular pattern, as best seen in FIGS. 6 and 8. The plate 26 includes a top surface 56, a bottom surface 58 opposite the top surface 56 and facing the top-most row 12 of milk crates 14 and has a thickness 60 extending from the top surface 56 to the bottom surface 58. Preferably, the plate bottom surface 58 is flat. The peg bottom end 34 is located below the plate bottom surface 58.

Optionally, for each group 28, adjacent pegs 30 are spaced approximately the same distance apart. Optionally, all adjacent pegs 30 are spaced approximately the same distance apart as shown in FIG. 8. Optionally, for each group 28, adjacent pegs 30 are spaced between about 1.25 inches apart. Optionally, the plate 26 comprises aperture handles 46 located on opposite sides of the plate 26.
