This application is a divisional of pending U.S. patent application entitled “STACKABLE CONTAINER APPARATUS AND METHODS”, and assigned continuation reissue of reissue application Ser. No. 12/966,775 filed on Dec. 13, 2010, and is a reissue of U.S. Pat. No. 7,740,138 issued Jun. 22, 2010 which claims benefit to U.S. Ser. No. 11/128,923, filed on May 12, 2005.
This invention relates to containers for storing and transporting products, such as electronics equipment, and more specifically, to stackable container apparatus and methods.
A wide variety of products are stored and transported in containers. It is often desirable to stack the containers during storage and transport to effectively utilize the available space within the storage facility or the transport vehicle. A variety of containers are known which provide some capability to be stacked, including the various containers disclosed, for example, in U.S. Pat. No. 6,457,599 B1 issued to Apps et al., U.S. Pat. No. 6,237,758 B1 issued to Hsu, U.S. Pat. No. 6,186,345 B1 issued to Robertson, U.S. Pat. No. 6,085,467 issued to Packrall et al., U.S. Pat. No. 5,769,230 issued to Koefelda, U.S. Pat. No. 5,203,494 issued to Blomfield, and U.S. Pat. No. 4,655,360 issued to Juhanson. Although desirable results have been achieved using such prior art containers, there is room for improvement.
The present invention is directed to stackable container apparatus and methods. Embodiments of apparatus and methods in accordance with the present invention may advantageously provide an improved capability to stack a plurality of containers in a secure, non-sliding manner, and may substantially improve a user's ability to store products, and may also reduce or eliminate the need for specially-crafted foam inserts, in comparison with prior art containers.
In one embodiment, a container assembly in accordance with the invention includes a lid portion and a base portion coupleable to the lid portion and forming a containment space. The lid portion has an upper surface and includes a plurality of first raised members projecting outwardly from the upper surface, at least some of the first raised members cooperatively forming a plurality of first receiving areas. Similarly, the base portion has a lower surface and includes a plurality of second raised members projecting outwardly from the lower surface, at least some of the second raised members cooperatively forming a plurality of second receiving areas. The second receiving areas are adapted to fittingly receive a second plurality of first raised members of a like container assembly positioned below the lower surface, and the first receiving areas are adapted to fittingly receive a second plurality of the second raised members of another like container assembly positioned above the upper surface.
Preferred and alternate embodiments of the invention are described in detail below with reference to the following drawings.
FIG. 10 10A is an enlarged top elevational view of an upper stackable container engaged with the plurality of lower stackable containers in accordance with a further embodiment of the invention;
FIG. 10B is a close-up view of a raised cleat from FIG. 10A;
The present invention relates to stackable container apparatus and methods. Many specific details of certain embodiments of the invention are set forth in the following description and in
In one particular embodiment, the stackable containers 100 are formed of rotomolded polyethylene. In alternate embodiments, other suitable materials may be used. In another embodiment, the containers 100 may be hermetically sealable and shock resistant, and may be suitable for the transport of sensitive electronic equipment from a supplier to an end user. In a further embodiment, the stackable containers 100 are sized and adapted for use in conjunction with the United States military's most common air transport pallet, the 463L, and standard cargo netting.
In one particular embodiment, each of the raised bosses 112 has an approximately square shape measuring 2.5 inches by 2.5 inches when viewed from above (
In one embodiment, as shown in
In one particular embodiment, the raised cleats 134A and the raised bosses 112B are sized and adapted so that the raised bosses 112B engage against the lower surface 132A of the lower portion 130A of the upper container 100A, and the raised cleats 134A engage against the upper surface 116B of the lid portion 110B of the lower container 100B. The contact between the raised bosses 112B and the lower surface 132A, and the contact between the raised cleats 134A and the upper surface 116B, may advantageously improve the load carrying capabilities of the containers 100A, 100B, and may reduce or prevent deformation of the lid and base portions 110B, 130A under heavy loads, elevated temperatures, or other operating conditions.
Similarly, in a further embodiment, at least one of the first and second ridges 136A, 138A of the lower portion 130A of the upper container 100A are sized and adapted to engage with the ribs 118B of the lid portion 110B of the lower container 100B. Again, this contact between the ridges 136A, 138A, and the ribs 118B may improve the load carrying capabilities of the containers 100A, 100B, and may reduce or prevent deformation of the lid and base portions 110B, 130A.
Embodiments of the present invention may provide significant advantages over prior art stackable containers. Because the raised cleats 134A of the base portion 130A are engaged into the first receiving areas 115B of the lid portion 110B, and the raised bosses 112B of the lid portion 110B are engaged into the second receiving areas 135A of the base portion 130A, the upper container 100A may be securely engaged with the lower container 100B in the stacked position (
Furthermore, because the second receiving areas 135A of the base portion 130A are formed over the lower surface 132A by the cooperation of the raised cleats 134A (and the first and second ridges 136A, 138A) rather than by forming indentations or recesses in the lower surface 132A, an inside surface (not shown) of the base portion 130A (opposite from the lower surface 130A) may remain relatively smooth and even. The resulting relatively smooth inner surface may substantially improve a user's ability to store products in the container 100A, and may advantageously reduce or eliminate the need for specially-crafted foam cushions having relief cuts, indentations, or other means of accommodating the protrusions or irregularities that exist on the inner surfaces of at least some prior art containers. Similarly, because the first receiving areas 115B of the lid portion 110B are formed over the upper service 116B by the cooperation of the raised bosses 112B (and the raised ribs 118B), an inner surface (not shown) of the lid portion 110B (opposite from the upper surface 116B) also remains relatively smooth and even, which may also substantially improve a user's ability to store products in the container 100B.
Embodiments the present invention may also provide improved interlocking features between successive layers of stackable containers 100. For example,
FIG. 10 10A is a partial top elevational view of an upper stackable container 200 engaged with the plurality of lower stackable containers 100 of
In operation, a user may lift upwardly on the handle member 154 until the support arm 152 engages with the support surface 164 in the deployed position 160. If the user provides further lifting force on the handle member 154, the support arm 152 is prevented from further up for rotation by the support surface 164. After the container 100 is lifted and moved to a desired position, the support arm 152 may be rotated downwardly into the stowed position 162. In the stowed position 162, the support arm 152 and handle member 154 are contained within the recess 158.
Embodiments of the present invention may provide further advantages in comparison with the prior art. For example, in the deployed position 160, because the support arm 152 is prevented from further rotation upwardly by the support surface 164, the user may exert a lifting force on the handle member 154 without causing the handle member 154 to pinch the user's hand against an outer surface of the base portion 130. Similarly, in the stowed position 162, because the support arm 152 and handle member 154 may be disposed within the recess 158 in the base portion 130, the support arm 152 and handle member 154 may be at least partially protected from damage, and may allow a tighter packing between adjacent containers 100.
Alternate embodiments of the present invention may be conceived, and it will be appreciated that the invention is not limited to the particular embodiments described above and shown in
In a further embodiment, as shown in
While preferred and alternate embodiments of the invention have been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of these preferred and alternate embodiments. Instead, the invention should be determined entirely by reference to the claims that follow.
