1. Field of the Invention
The present invention generally relates to crates.
2. Description of Related Art
Conventional milk crates have a rectangular-shaped bottom, four rectangular side walls and an open-ended top. Unfortunately, stacking such milk crates may take up a large amount of space, making them inefficient to store. Because they are inefficient to store, they are often stacked outside of buildings and other structures, making them susceptible to weather damage and to theft.
A need therefore exists for a crate that eliminates or diminishes the disadvantages and problems described above.
One aspect is a system that may include one or more crates. The crates may each include, for example, a floor and side walls. The crates may be arranged in a variety of relative positions and/or orientations. When in a first relative position, the crates may be arranged in a stacked arrangement in which the crates are positioned to hold and/or store items. When in a second relative position, the crates may be arranged in a nested, more compact arrangement in which at least a substantial portion of an upper crate may be disposed within an adjacent lower crate.
Another aspect is a plurality of crates that may be positioned in a stacked arrangement and a nested arrangement. The height of the crates 10 in the nested arrangement may be less than about 50 percent, 40 percent, 30 percent and/or 20 percent of the height of the crates in the stacked arrangement. Moreover, the ratio of the height of the crates 10 in the stacked arrangement to the height of the crates in the nested arrangement may be at least about 2, 3, 4 and/or 5 to 1. For example, in one embodiment, at least about one hundred fifty nested crates may fit into the space that thirty stacked crates may occupy. The crates may thus provide significant advantages. For example, items may be placed into crates for storage and the crates may then be stacked. When the crates are no longer being used to store and/or carry the items, the empty crates may be nested and stored in a much smaller area than they occupied when stacked. Significantly, this may allow more of the empty crates to be stored inside secured areas and/or areas out of the weather, which may help prevent weather damage to, and/or theft of, the crates
Yet another aspect is a crate that may include one or more alignment and/or interlocking portions. The alignment and/or interlocking portions may be sized and configured to align and/or interlock the crates when in the stacked arrangement and/or the nested arrangement.
A further aspect is the crates may include a support that may interconnect opposing side walls. When in the nested arrangement, the supports of a pair of adjacent crates may be aligned to allow the supports to nest within and/or interlock with each other. In addition, when the crates are in the stacked position, the supports of the pair of adjacent crates may be generally offset, which may allow the support of the lower crate to contact one or more portions of the upper crate to help stabilize the upper crate. In some instances, the support of a crate may extend along at least a substantial portion of the height of its side walls, which may advantageously help strengthen, stiffen and/or reinforce the side walls and the crate.
Another further aspect is the crates may include side walls that may include one or more projections and/or receiving portions. The projections and/or receiving portions may interlock with each other when the crates are in the nested arrangement. The projections may also help align, support and/or stabilize the crates when in the stacked arrangement. For example, when the crates are in the stacked arrangement, the projections of the lower crate may contact, abut and/or engage an exterior surface of the upper crate, which may help align, support and/or stabilize the upper crate. In some instances, the projections of a crate may extend along at least a substantial portion of the height of its side walls, which may advantageously help strengthen, stiffen and/or reinforce the side walls and the crate.
Yet another further aspect is that one or more portions of side walls of the crates may extend inwardly. When the crates are in the stacked arrangement, the inwardly extending portions of the side walls of the lower crate may contact, abut and/or engage an exterior surface of the side walls of the upper crate, which may help align, support and/or stabilize the upper crate. When the crates are in the nested arrangement, the inwardly extending portions of the side walls of the upper and lower crates may interlock with each other.
Still another aspect is a crate that may be constructed from plastic using a molding process, such as compression molding, injection molding and/or any other suitable molding process. Desirably, if the crate is constructed from plastic using a molding process, some or all of the crate's features may be quickly and easily integrally formed in the crates as part of unitary one-piece construction during the molding process. It will be appreciated, however, that the crates need not have a unitary, one piece construction. It will also be appreciated that the crates need not be constructed from plastic or using a molding process and may be constructed from plastic, wood, metal and/or any other desired material using any other desired manufacturing process.
Another aspect is a first crate and a second crate that may be arranged in a plurality of stacked positions and a plurality of nested positions. In particular, the crates may be arranged in a first nested position in which the first crate is nested within the second crate and a second nested position in which the second crate is nested within the first crate. In addition, the crates may be arranged in a first stacked position in which the first crate is stacked upon the second crate and a second stacked position in which the second crate is stacked upon the first crate. The crates may, for example, be at least substantially interchangeable to allow the crates to be arranged in these various stacked and nested positions.
These and other aspects, features and advantages of the present invention will become more fully apparent from the following detailed description of preferred embodiments and appended claims.
The appended drawings contain figures of preferred embodiments to further illustrate and clarify the above and other aspects, advantages and features of the present invention. It will be appreciated that these drawings depict only preferred embodiments of the invention and are not intended to limit its scope. The invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
The present invention is generally directed towards crates. The principles of the present invention, however, are not limited to crates. It will be understood that, in light of the present disclosure, the crates disclosed herein can be successfully used in connection with other types of storage, shipping and/or organization systems.
Additionally, to assist in the description of the crate, words such as top, bottom, front, rear, right and left may be used to describe the accompanying figures, which are not necessarily drawn to scale. It will be appreciated, however, that the crate can be located in a variety of desired positions and/or orientations. A detailed description of the crate now follows.
As shown in
The crate 10 may be sized and configured to hold and/or store containers, such as cartons, jugs, bottles, etc. For example, the crate 10 may be sized and configured to hold and/or store one or more containers that hold beverages (such as milk, water, orange juice or other beverages) and/or other liquids. The crate 10 may, for instance, may have a generally square or rectangular shape and may form a first, generally rectangular receptacle 22 sized and configured to receive one or two one-gallon-sized containers and a second, generally rectangular receptacle 24 sized and configured to receive one or two one-gallon-sized containers. It will be appreciated, however, that the crate 10 may form a single receptacle or two or more receptacles sized and configured to receive any number of larger or smaller capacity containers. It will also be appreciated that the crate 10 and/or the receptacles 22, 24 do not require generally square or rectangular shapes and may have other suitable shapes. Moreover, it will be appreciated that the receptacles of the crate 10 need not be sized and configured to receive containers and, instead, may be sized and configured to receive any other desired item that the crate 10 is intended to hold and/or store.
As shown in
When the pair of adjacent crates are in a second relative position shown in
Desirably, the height of the crates 10 in the nested arrangement may be substantially less than the height of the crates in the stacked arrangement. For example, the height of the crates 10 in the nested arrangement may be less than about 50 percent, 40 percent, 30 percent and/or 20 percent of the height of the crates in the stacked arrangement. Moreover, the ratio of the height of the crates 10 in the stacked arrangement to the height of the crates in the nested arrangement may be at least about 2, 3, 4 and/or 5 to 1. For instance, in one embodiment, at least about one hundred fifty nested crates 10 may fit into the space that thirty stacked crates may occupy. It will be appreciated, however, that the heights of the stacked or nested crates 10 and/or the ratios thereof may be larger or smaller depending, for example, upon the particular size and configuration of the crates.
The crates 10 may include one or more alignment and/or interlocking portions. As discussed below, the alignment and/or interlocking portions may be sized and configured to align and/or interlock the crates when in the stacked arrangement and/or the nested arrangement.
In further detail, the crates 10 may include one or more supports 26 shown in
In contrast, when a pair of adjacent crates are in the stacked position, the support 26 of the upper crate 10a and the support 26 of the lower crate 10b may be generally offset, for example, at about 90 degrees offset from each other. This may allow the support 26 of the lower crate 10b to contact one or more portions of the upper crate 10a to help support and/or stabilize the upper crate 10a. In greater detail, the floor 12 of the crates 10 may include one or more receiving portions 30 (such as grooves, channels, slots or other receiving portions) that may receive and/or interlock with one or more supports 26. To help support and/or stabilize the upper crate 10a, the lower crate's support 26 may contact, abut and/or engage the receiving portion 30 of the upper crate. When more than two crates are in the stacked position, the orientations of the supports 26 of the crates may alternate—such that the supports of adjacent crates may be generally offset, but the supports of odd-numbered-positioned crates may be generally aligned and the supports of even-numbered-positioned crates may be generally aligned.
The side walls 14, 16, 18, 20 of the crates 10 may include one or more projections 32 and receiving portions 34 that may interlock with each other when the crates are in the nested arrangement. In further detail, as shown in
The projections 32 may also be sized and configured to help align, support and/or stabilize the crates 10 when in the stacked arrangement. For example, when the crates are in the stacked arrangement as shown in
As shown in
As shown in
As shown in
The support 26 may also be located in a generally central portion of the crate 10 and may interconnect generally central portions of the side walls 16, 20. Significantly, if the support 26 is located in a generally central portion of the crate 10 and interconnects generally central portions of the side walls 16, 20, the support may provide balanced strength to and/or reinforcement of the side walls and the crate 10. Moreover, if the support 26 is located in a generally central portion of the crate 10, the support 26 may help form a pair of at least substantially equal-sized receptacles 22, 24, each of which can, as discussed above, be optionally sized and configured to hold two one-gallon-sized containers. It will be appreciated, however, that the support 26 need not be located in a generally central portion of the crate and may be positioned in any other desired location. It will also be appreciated the support 26 is not required.
As shown in
The projections 32 on the interior surface of a single side wall may be generally aligned with the receiving portions 34 on the exterior surface of that side wall. Desirably, if the projections 32 on the interior surface of the side wall are generally aligned with the receiving portions 34 on the exterior surface of that side wall, this may allow the projections and receiving portions to be more quickly and easily manufactured. For example, where the crate is formed from plastic using a molding process and the projections 32 and the receiving portions 34 of the side wall are generally aligned, the projections 32 and the receiving portions 34 of the side wall may be formed using a single feature of a mold. Moreover, if the projections 32 of the side walls 14, 18 are generally aligned and project towards each other as shown in
To further help the projections help the projections and receiving portions interlock with each other when the crates are in the nested arrangement, the side walls 14, 18 may include a first projection 32 and a second projection 32 shown in
If desired, the crates 52a, 52b may have the same features as, or similar features to, the crates 10a, 10b and/or may have other features. Thus, for example, the crates 52a, 52b may be stacked as shown in
As shown in
The crates 10, 52 may also include one or more vents. For example, as shown in
As shown in
If desired, the upper and lower crates may have at least substantially the same sizes, shapes, configurations and/or features, which may advantageously help the upper and lower crates be at least substantially interchangeable when nested and/or stacked. It will be appreciated, however, the upper and lower crates may have substantially different sizes, shapes, configurations and/or features and need not be interchangeable.
The crates 10, 52 may be constructed from plastic using a molding process, such as compression molding, injection molding and/or any other suitable molding process. Desirably, if the crates 10, 52 are constructed from plastic using a molding process, some or all of the crates' features may be quickly and easily integrally formed in the crates as part of unitary one-piece construction during the molding process. For example, the floors 12, 62; the side walls 14, 16, 18, 20, 48, 50, 56, 58; the receptacles 22, 24; the support 26; the receiving portions 28, 30, 34; the projections 32, 54; the ledges 36; the ribs 38, 40, 42; the inwardly extending portions 44, 46 the side walls 16, 20; the slots 60; the vents 64; and/or any other features may be integrally formed in the crates as part of unitary one-piece construction during the molding process. It will be appreciated, however, that the crates 10, 52 need not have a unitary, one piece construction. It will also be appreciated that the crates 10, 52 need not be constructed from plastic or using a molding process and may be constructed from plastic, wood, metal and/or any other desired material using any other desired manufacturing process.
In view of the foregoing, the crates 10, 52 may have significant advantages. For example, items may be placed into crates 10, 52 for storage and the crates may then be stacked. When the crates 10, 52 are no longer being used to store and/or carry the items, the empty crates may be nested and stored in a much smaller area than they occupied when stacked. Significantly, this may allow more of the empty crates 10, 52 to be stored inside secured areas and/or areas out of the weather, which may help prevent weather damage to, and/or theft of, the crates.
Although this invention has been described in terms of certain preferred embodiments, other embodiments apparent to those of ordinary skill in the art are also within the scope of this invention. Accordingly, the scope of the invention is intended to be defined only by the claims which follow.
