This invention relates to a molded plastic storage crate.
Plastic open-top storage crates find great utility. Many times, such crates are used to store toys, crafting supplies, household articles and other irregularly-shaped objects. When crates are filled with objects, the surface is irregular, which makes stacking filled crates one upon another difficult to accomplish. As a result, the number of crates that can be stored in a closet or another area with limited floor space is less than it could be.
Another issue with crates is that retailers desire to display a maximum number of crates in a minimal floor or shelf space. It is thus advantageous to have crates nest one within another.
It is therefore an object of this invention to provide a storage crate that nests with other crates when empty, and in which the crates can be stacked one upon another. The nesting is accomplished by making the top rim define an open top that is larger than the bottom of the crate. As a result, the sidewall is tapered inwardly from top to bottom. This allows the crates to be nested one within the other to thereby decrease the storage space required for multiple crates, a feature useful both for the retailer and the purchaser. The crates are designed to be stacked one on top of another, even when essentially filled. This is accomplished by a pair of shelves formed into the sidewalls, near the rim. The shelves are sized and spaced so that the bottom of another identical crate can rest on the shelves, with the upper crate spanning the open top between the shelves and rotated ninety degrees relative to the crate on which it rests.
In the preferred embodiment, the crate is essentially rectangular, and the sidewall defines pairs of essentially parallel opposite walls. However, the crate could take other shapes such as oval and still accomplish the invention through the combination of spaced shelves and an appropriately-shaped and sized bottom. The crate is preferably made from injection-molded plastic.
The shelves are preferably closer to the top rim than they are to the bottom. The shelves are preferably on opposite sides of the crate. The shelves each preferably comprise a top surface that is generally planar, and may each further comprise an interior lip projecting above the plane of the top surface. The shelves may each further comprise a series of ribs below the top surface.
The top rim and the bottom may be generally rectangular, in which case the sidewall may comprise four generally planar portions that define four sides of the rectangle, with the shelves in two opposite sidewall portions. The shelves may extend along most of the length of the two opposite sidewall portions. The nesting and stacking storage crate may further comprise pillars connecting the top rim and bottom at each of the corners of the rectangle. The sidewall between the pillars may comprise a series of openings.
The nesting and stacking storage crate may further comprise a series of standoffs located at spaced locations around and below the rim. The nesting and stacking storage crate may further comprise carrying handles. The carrying handles may comprise the undersides of the shelves. The bottom may have opposite sides, and the distance between the shelves may be about the same as the distance between the opposite sides of the bottom.
In a more specific embodiment, the invention features a nesting and stacking storage crate, comprising a generally rectangular bottom, a generally rectangular top rim that defines an open top, wherein the top rim defines an open top that is larger than the bottom, a sidewall connecting the bottom and the top rim, the sidewall comprising four generally planar portions that define four sides of the rectangle, and a pair of shelves formed into the sidewall on two opposite sidewall portions close to the rim, the shelves spaced from one another about the same distance as opposite sides of the bottom so that they can support the bottom of another identical storage crate.
Other objects, features and advantages will occur to those skilled in the art from the following description of the preferred embodiments and the accompanying drawings in which:
Nesting and stacking storage crate 10 may be made from injection-molded plastic material such as copolymer-polypropylene. Crate 10 comprises generally rectangular bottom 42, and generally rectangular top rim 40 that defines an open top that is larger than bottom 42. The sidewall connecting the bottom and top comprises inwardly-tapered sidewall portions 43-46. In this preferred embodiment, sidewall portions 43 and 44 are essentially planar and parallel, as are sidewall portions 45 and 46. However, this is not a limitation of the invention, as will become apparent below.
Sidewall portions 43 and 44 define near their tops shelves 12 and 14, respectively. Shelf 14 is shown in detail in
The crate is designed such that the distance between the shelves is about the same as the distance between the opposite ends of the bottom of the crate on the sides adjacent to the sides with the shelf. In other words, the distance between the outer most section of shelves 12 and 14 needs to be at least as great as the distance between the bottom of sidewall sections 45 and 46. This allows the crates to be stacked in a cross-wise fashion as shown in
The crate preferably also defines a pair of handles 15 and 13 that are integrally formed in rim 40, as best shown in
The crates are also adapted to nest together as shown in
Solid corner pillars such as pillars 22 and 24 are another optional feature of the invention. These provide some strength and rigidity in the case of the preferred embodiment in which the remaining portions of the sidewall has a series of through holes that provide both visibility and ventilation. The solid pillars in this case provide the strength necessary to allow the vertical stacking of two or more crates.
Although specific features of the invention are shown in some drawings and not others, this is for convenience only as some feature may be combined with any or all of the other features in accordance with the invention.
Other embodiments will occur to those skilled in the art and are within the following claims.
