COLLAPSIBLE CONTAINER
A collapsible container includes a base having a pair of opposed first edges and a pair of opposed second edges. The base has a generally planar portion having a plurality of first drainage channels formed along the first edges, a plurality of second drainage channels formed along the second edges and a plurality of third drainage channels formed perpendicularly to the first drainage channels between the second drainage channels. The second drainage channels and the third drainage channels are in fluid communication with the first drainage channels. The first, second and third drainage channels form drag rails on an underside of the base that are the lowest surfaces of the base.
Reusable plastic containers are often used for shipping packages of food to stores. Frozen or refrigerated meat may be stored in plastic bags that are then placed in the reusable plastic container. The plastic bags may be damaged by sharp edges on the interior surfaces of the plastic container. Further, the plastic bags may leak liquid into the plastic container.
SUMMARYA collapsible container includes a base having a pair of opposed first edges and a pair of opposed second edges. The base has a generally planar portion having a plurality of first drainage channels formed along the first edges, a plurality of second drainage channels formed along the second edges and a plurality of third drainage channels formed perpendicularly to the first drainage channels between the second drainage channels. The second drainage channels and the third drainage channels are in fluid communication with the first drainage channels. The first, second and third drainage channels form drag rails on an underside of the base that are the lowest surfaces of the base.
The drag rails on the underside of the base may be spaced apart to define a longitudinal stacking channel extending through the entire longitudinal dimension of the underside of the base. The drag rails on the underside of the base may also be spaced apart to define a plurality of lateral stacking channels each extending through the entire lateral dimension of the underside of the base. The stacking channels permit the containers to be cross-stacked and provide for a more stable stack.
An example embodiment of a collapsible container 10 is shown in
The base wall of the base 12 is a generally planar portion formed into a plurality of longitudinal drainage channels 38, 39 and intersecting lateral drainage channels 36, 37. Outer longitudinal drainage channels 38 connect to end lateral drainage channels 36 in the corners of the base 12. A center longitudinal drainage channel 39 is between two outer longitudinal drainage channels 38 along each side edge of the base 12. Interior lateral drainage channels 37 extend perpendicularly to the longitudinal drainage channels 38, 39, between the ends of the base 12. A different number and a different arrangement of channels 36, 37, 38, 39 could be used but the disclosed number and arrangement provides some benefits in this particular application.
Referring to
The longitudinal drainage channels 38, 39 extend adjacent the side walls 14 (i.e. adjacent the side flanges 18 (
The lateral drainage channels 36, 37 are each elongated in a direction parallel to the end walls 16. There are two spaced-apart end lateral drainage channels 36 adjacent each end wall 16 (i.e. adjacent each end flange 20 (
The spaces between the lateral drag rails 46, 47 form the longitudinal stacking channel 52 that extends entirely through the length of the base 12. Spaces between the longitudinal drag rails 48,49 form two lateral stacking channels 54 entirely through the width of the base 12.
Thus any liquids that may leak from contents in the container 10 will drain from the support surfaces 40 into the longitudinal drainage channel 38 and the lateral drainage channels 36. This initially keeps the liquids from the support surfaces 40 on which the contents of the container 10 are supported. The base wall of the base 12 does not include openings through it and thus will retain liquids in the base 12 until hinge openings through the flanges 18, 20 are reached. Optionally, slots can be added in the end flanges 20 or side flanges 18 of the base 12 at a specific height in order to control the volume of fluid capacity. The slots may be at the same height of the hinge openings, or they may be lower, depending on the desired volume to be retained. The slots will also help with drainage during the washing and drying process.
Additionally, the interior surface of the bottom of the base wall is product-friendly, with no sharp edges or protruding ribs throughout the entire bottom section of the base 12. As such, the bottom of the base 12 was designed with smooth drainage channels 36, 38 and raised support surfaces 40 to create a stiff design without the use of ribs or sharp edges. This soft bottom profile ensures that packages do not get ripped, torn, or damaged when placed inside the container.
As shown, the second layer is oriented 180 degrees relative to the first layer, such that the three containers 10 in the second layer are substantially arranged on top of the four containers 10 in the first layer, and the 2×2 containers 10 in the second layer are substantially arranged on top of the three containers 10 in the first layer.
In
The base 12 is integrally molded as a single piece of suitable plastic, as are each of the side walls 14 and end walls 16.
In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
