1. Field
The present invention relates to an apparatus for positioning containers, and in particular, reusable plastic containers, on a support surface.
2. Background
Groceries, such as produce, or other objects are typically placed in containers, such as reusable plastic containers, which are placed on support surfaces, such as tables, for display in stores. To place the containers containing the groceries or other objects onto the tables, each container typically has to be lifted and placed directly at the desired location. The containers are typically heavy when full. To enable multiple rows of heavy containers to be placed on the support surface, the containers for the upper rows are lifted and placed above the lower rows of containers. Accordingly, an improved apparatus and method are needed to place heavy containers on support surfaces used to display the objects in the containers.
According to an aspect of the invention, there is provided an apparatus for positioning containers on a support surface of a support, the apparatus including an engagement portion constructed and arranged to attach the apparatus to the support. The apparatus also includes a first portion extending from the engagement portion. The first portion is constructed and arranged to rest on the support surface and enable sliding movement of a container thereon. The apparatus also includes a second portion constructed and arranged to rest on the support surface and enable sliding movement of the container thereon. The apparatus further includes a stop portion in between the first portion and the second portion. The stop portion is constructed and arranged to position the container at a predetermined position on the support surface.
According to an aspect of the invention, there is provided a method for positioning containers on a support surface using a container positioning apparatus. The method includes engaging an engagement portion of the apparatus with at least a portion of the support surface and placing a first container onto a first portion of the apparatus. The method also includes sliding the first container on the first portion towards the stop portion and over the stop portion and sliding the first container onto a second portion of the apparatus. The method further includes retaining the first container on the second portion using the stop portion, and placing a second container on the first portion.

A lip portion 40 may be formed at one end of extension portion 38 such that a plane defined by lip portion 40 is generally perpendicular to the plane formed by extension portion 38 and generally parallel to the plane formed by rear portion 34. The lip portion 40 functions with the extension portion 38 to facilitate removal of the containers 12 from the apparatus 10. In other words, the lip portion 40 and the extension portion 38 help prevent the containers 12 from catching on the apparatus 10 when the containers 12 are slid away from the stop portion 24 during removal of the containers 12 from the apparatus 10, which will be described in more detail below. A portion of first portion 22, rear portion 34 of engagement portion 20, and bottom portion 36 of engagement portion 20 may define a receiving space 42 constructed and arranged to receive at least a portion of support 15. Accordingly, when apparatus 10 is engaged with support 15, a portion of support 15, for example, an edge of support 15, is received within receiving space 42 of apparatus 10. As such, in one embodiment, engagement portion 20 and a portion of first portion 22 may form a C-shaped structure that enables apparatus 10 to “hook” onto support 15. In embodiments where support 15 is a slat table, receiving space 42 may receive a portion of slat 16 such that engagement portion 20 is “hooked” onto slat 16 of the slat table. Optional openings 37 may be provided on bottom portion 36 of apparatus 10, openings 37 being constructed and arranged to receive screws or other attachment mechanisms that enable apparatus 10 to be removably fixed to support 15.
As described above, apparatus 10 may be made of integrally formed portions. For example, first portion 22, second portion 26, stop portion 24, and engagement portion 20 may be integrally formed. In one embodiment, apparatus 10 may be manufactured or formed using a single sheet of material, just for example, steel sheet metal. The sheet metal may be stamped to form the various portions of apparatus 10. In one embodiment, stop portion 24 may be formed by stamping (e.g., bending) the sheet metal between first portion 22 and second portion 26. Stop portion 24 may be constructed and arranged to enable container 12 to be both lifted and slid over stop portion 24, and retained on a first portion 22 so as to prevent sliding movement of container 12 towards second portion 26 when apparatus 10 is on an inclined support surface 14. In some embodiments, ball bearings may be provided on stop portion 24 to facilitate sliding movement of containers 12 over stop portion 24. A portion of the sheet metal may be cut (e.g., by laser cutting, punch pressing, or other methods) to form extension portion 38, lip 40, and opening 35. That is, after the sheet metal has been cut along edges 44, 46, and 48, rear portion 34 of apparatus 10 may be formed by stamping (e.g., bending) a portion of the sheet metal perpendicular to the rest of the sheet metal. Accordingly, extension portion 38 is formed and extends past first portion 22 after rear portion 34 has been formed by the bending of the sheet metal. Lip 40 may be formed by stamping (e.g., bending) a portion of the sheet metal at an end of extension portion 38. Bottom portion 36 may be formed by stamping (e.g., bending) the sheet metal again after rear portion 34 has been formed such that bottom portion 36 is generally perpendicular to rear portion 34. In one embodiment, manufactured apparatus 10 may be about 40.7 inches in length and about 9.5 inches in width. In some embodiments, apparatus 10 has a width that is about ⅔ of the width of container 12. It should be appreciated that the measurements of the entire apparatus 10 and any portions of apparatus 10 may vary.
Apparatus 10 may include a friction-reducing treatment 23 on a surface thereof to facilitate sliding of the containers thereover. In one embodiment, friction-reducing treatment 23 may comprise a hammer finish, while in an alternate embodiment, friction-reducing treatment 23 may comprise a powder coating. It should be appreciated that apparatus 10 may be provided with any of a variety of friction-reducing treatments and should not be limited to the previously described embodiments.
The above described method of manufacturing apparatus 10 is not intended to be limiting, and it should be appreciated that in some embodiments, apparatus 10 may be formed using other methods and using various materials, and any of the portions of apparatus 10 may be separately formed and then connected together to form apparatus 10. It should also be appreciated that in some embodiments, engagement portion 20 may be made of different materials from the rest of apparatus 10. For example, in some embodiments, engagement portion 20 may be made of resilient materials that enables engagement portion 20 to “clamp” onto a portion of support 15. It should be appreciated that other clamping functions or clamps may be added in other embodiments. Apparatus 10 may also be made of other materials, such as, just for example, various types of metals, wood, plastic, cardboard, or a combination thereof.
Apparatus 10 may be used to facilitate positioning of containers 12, such as the reusable plastic containers, as follows in accordance with an embodiment. A container 12 to be positioned on second row 32 may be lifted and placed on second portion 26 of apparatus 10. One end of container 12 may then be slightly lifted onto stop portion 24, and then slid over stop portion 24 and onto first portion 22 and then slid into place on first portion 22. In embodiments where support surface 14 is inclined, stop portion 24 prevents the sliding movement of container 12 downwards towards second portion 26. Another container 12 may be lifted and placed onto second portion 26 to form first row 30.
To remove containers 12 from apparatus 10, container 12 on second portion 26 may be lifted off of apparatus 10. To remove container 12 from second row 32, container 12 may be slid a short distance on first portion 22 in a direction away from stop portion 24 and onto extension portion 38. The extension portion 38 and the lip portion 40 of the apparatus 10 may facilitate the sliding movement by preventing the containers 12 from catching on the apparatus 10 during sliding movement away from the stop portion 24. One end of container 12 may then be slightly lifted onto stop portion 24 and slid over stop portion 24 and onto second portion 26 in a controlled manner. Container 12 may then be lifted off of second portion 26.
Apparatus 10 enables and facilitates the stacking of filled containers 12 into rows without having to form first row 30 and then form second row 32 of containers 12 by lifting filled containers 12 and placing them above containers 12 in first row 30. Instead, apparatus 10 enables containers 12 to simply be placed on first row 30, slightly lifted above stop portion 24, slid over stop portion 24, and then slid into second row 32 and retained at a predetermined position on support surface 14 by stop portion 24 of apparatus 10.
