This invention relates to a storage container and more particularly to a storage container with improved tamper-resistant features.
Known portable storage containers include two end walls and two side walls extending upwardly from the periphery of a base. Lid halves are each hingeably connected to an upper edge of one of the side walls. Apertures in the overlapping edges of the lid halves are aligned with one another and with apertures through the upper edges of the end walls. Locks through the apertures secure the container closed. Overlapping, interlocking leaves at inner edges of the lid halves prevent intrusion between the lid halves.
In some known containers, it is possible to disassemble the hinged connection of the lid halves to the side walls. Therefore, even though the inner edges of the lid halves are secured, the container can be accessed by unauthorized people. Additionally, in the known containers, moisture can seep between the interlocking leaves between the lid halves.
An example storage container according to the present invention includes a base having side walls and end walls extending upwardly from the base. Lid halves are hingeably connected to upper edges of the side walls. The upper surface of the lid halves includes a lip along the outer edge adjacent the hinge to prevent moisture from seeping into the storage container between the lid halves and the hinges.
Stops project upwardly from each lid half above the end walls and recesses within the end walls adjacent the base align with the stops, such that stops would be received within the recesses of an adjacent container to increase the stability of a stack of containers.
A security recess is formed on an inner surface of the side walls adjacent to each hinge. Each security recess is aligned with a corresponding security tab projecting from the lid halves. When the lid is in the closed position, each security tab is received in a security recess, thus preventing vertical movement of the outer edge of the lid half.
The inner edge of each lid half includes upper and lower leaves that overlap with upper and lower leaves on the opposing lid half. The lower leaves each include a plurality of protrusions behind a lip extending upwardly from the lower leaf. The lip helps prevent any moisture that seeps between the lid halves from entering the container.
One of the lid halves includes a pocket for holding an identification ticket for shipping the storage container. The pocket includes a recess adjacent an opening to the pocket to assist in grasping the ticket more easily.
Each lid half includes an upward projection for contacting the wall adjacent a recess when the lid half is partially closed. The projection provides sufficient interference to keep the lid partially open under its own weight, but can easily be overcome by pressing down on the lid half.
These and other features of the present invention can be best understood from the following specification and drawings, the following of which is a brief description.
A storage container 10 according to a first embodiment of the present invention is illustrated in
Each of the lid halves 18, 20 further includes stops 28, 30 projecting upwardly from opposite edges above the end walls 16, 17. The stops 30 above end wall 16 also include lateral projections 32 extending from the stops 30. The end wall 16 includes a pair of recesses 44 adjacent the base 12. The recesses 44 are aligned with the lateral projections 32 on the stops 30, such that lateral projections 32 on a subjacent like container 10 would be received within the recesses 44 to increase the stability of a stack of containers 10. The lid halves 18, 20 include lock apertures 34 inward of the stops 28, 30. The inner edge of each lid half 18, 20 includes a plurality of interlocking upper leaves 40.
As shown in
As shown in
The inner edge of each lid half 18, 20 includes the upper leaves 40 alternating with lower leaves 66, such that the upper leaves 40 of one lid half 18, 20 overlap onto the lower leaves 66 of the other lid half 18, 20.
First, referring to
The second additional feature of the second embodiment is shown most clearly in
The third additional feature of the second embodiment can be seen most clearly in
The storage containers 10, 110, including lid halves 18, 20, 118, 120, are preferably injection molded from a plastic material, such as high density polyethylene (HDPE), but other materials and processes could also be used. As indicated above, one or more features from either embodiment can be incorporated into the other embodiment.
While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
