(1) Field of the Invention
The present invention generally relates to a crate having sides with openings. In particular, the present invention is directed to a dairy crate having openings sized to prevent the insertion of a hook.
(2) Description of the Related Art
Crates are often used to transport dairy products such as milk. At dairies and in stores where the products are sold, grabbing tools such as hooks or similar instruments are often used to move the plastic crates. For crates that have solid sides with only a reinforced opening for a handle, the hooks are inserted through the handle opening. However, for crates that have both handle openings and other smaller openings on the side, the hooks are sometimes inserted through the smaller openings rather than the handle opening. However, smaller openings are typically not reinforced and tend to break when pulled on by a grabbing tool or instrument such as a hook.
One aspect of the present invention is a crate including a bottom and a plurality of sides extending upwardly from the bottom. Each of the plurality of sides are joined with the bottom and the plurality of sides are joined with one another to define an open top in the crate. At least one of the plurality of sides includes a first opening defining a handle and a plurality of secondary openings. Each of the plurality of secondary openings is sized to prevent the insertion of a grabbing tool.
Another aspect of the invention is a crate including a bottom having an outer edge and a plurality of sides extending upwardly from the bottom. Each of the plurality of sides is joined with the bottom and the plurality of sides are joined with one another to define an open top in the crate. At least one of the plurality of sides includes a first opening defining a handle and a plurality of secondary openings. The crate also includes a plurality of ribs, which are each positioned within one of the plurality of secondary openings.
For the purpose of illustrating the invention, the drawings show a form of the invention that is presently preferred. However, it should be understood that the present invention is not limited to the precise arrangements and instrumentalities shown in the drawings, wherein:
Referring now to the drawings in which like reference numerals indicate like parts, and in particular to
Crate 20 also includes a bottom 26, which is joined with sides 22. Sides 22 extend upwardly from bottom 26. Typically, crate 20 includes four of sides 22. However, in other embodiments, other numbers of sides 22 are possible, e.g., three, five, or more. Sides 22 are joined with one another to define an open top 28 in crate 20. Of course, in other embodiments, a lid (not shown) may also be includes. At least one of the plurality of sides includes a first opening 30 defining a handle. Each openings 24 is smaller than first opening 30. Referring to
As best shown in
Crate 20 is typically used as a dairy crate and is generally fabricated from a thermoplastic or the like, as sold by Norseman Plastics Ltd. of Ontario, Canada. Aspects of the present invention are not limited to a specific crate geometry, material, or use. Rather, it is contemplated that the present invention may be incorporated into any type of crate that is moved using a grabbing instrument such as a hook or similar device.
A crate according to the present invention offers advantages over prior art designs in that it reduces the damage caused to the crate by pulling on unreinforced openings on the sides of the crate inserting using grabbing tools such as hooks. Instead, a worker is forced to insert the hook into larger, reinforced openings, thereby reducing damage to the crate.
A crate according to the present invention that includes ribs offers additional reinforcement over prior art crates. The ribs help increase the strength of the crate sides thereby increasing the amount of stress they can withstand without failing.
Although the invention has been described and illustrated with respect to exemplary embodiments thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions and additions may be made therein and thereto, without parting from the spirit and scope of the present invention. Accordingly, other embodiments are within the scope of the following claims.
