1. Field of the Invention
The present invention relates to partitioning devices and, more specifically, to partitioning devices with hand holes for containers and carriers.
2. Description of the Prior Art
Prior art includes various inventions for the reinforcement of container handles. Container handles fail for a variety of reasons. In some cases, the contents are too heavy for the handles to support and they tear by compression and in-plane shearing, a condition termed “edge crush”. In other similar cases, the user grips the handles and presses down on the top of the box with his palm, squeezes excessively, resulting again in edge crush. In yet other cases, the user bends the handles out-of-plane, which is a weaker position than in-plane, and the handles tear under much less force. Various prior art inventions have been designed to reinforce the handles and prevent failure.
U.S. Pat. No. 4,867,373 for a carton divider incorporating 3-ply lifting handle, describes a combined divider and handle reinforcing insert for a paperboard carton is formed with a three-ply thickness. It further describes first and second divider panels each having an upper edge and a lower edge and oppositely disposed first and second end edges, first and second handle panels each having upper and lower edges and oppositely disposed first and second end edges, the lower edges of the first and second handle panels being connected to the upper edge of the first and second divider panels respectively.
U.S. Pat. No. 5,785,239 for a reduced material carton divider and method of producing same teaches a carton divider having vertically oriented longitudinal partitions and vertically oriented transverse partitions inter-engaged to form a grid of cells for receiving glass containers. It further describes a reinforcing strip which extends laterally on opposite sides of a vertical line bisecting said cell wall face and extends vertically for a distance spanning the vertical extent of said cell wall face.
U.S. Pat. No. 6,112,977 for a bottle carrier with dividers describes a carrier comprising of a top panel section, a first side panel section and an opposing second side panel section, a bottom panel section, and a divider section. It further describes that the divider section includes a handle reinforcement portion, a first divider panel, and a second divider panel. The handle reinforcement portion is attached to a handle grip portion in the top panel.
The present invention relates to partition sets for containers and carriers.
It is an object of this invention to provide a partition set for a container that reinforces the handles of the container.
Yet another object of this invention is to provide a container with a partition set that reinforces the handles of the container.
A further object of this invention is to provide a shrink-wrapped container with a partition set that reinforces the handles in the shrink-wrap.
Accordingly, a broad embodiment of this invention is directed to a container with a partition, the partition ends providing reinforcement to the container handles.
These and other aspects of the present invention will become apparent to those skilled in the art after a reading of the following description of the preferred embodiment when considered with the drawings, as they support the claimed invention.
Referring now to the drawings in general, the illustrations are for the purpose of describing a preferred embodiment of the invention and are not intended to limit the invention thereto.
The present invention provides a partition set for a container. The partition set is composed of subcomponents, shown in
The subcomponents are assembled into a partition, generally shown as 100 in
The partition set separates the container contents and provides reinforcement for the hand holes in the container. The partition end panels 30 fold to abut against the handle sides 40 of a container 45. The end panel hand holes 35 match and align with the hand holes 60 in the sides of container when the end panels are folded and abutted against the sides of the container, as shown in
In cases where the container includes a top, the partition set is designed and configured to abut against the top when the container is closed (not shown). In this manner, the partition set also provides support against compression tearing. That is, the partition set abuts against the top and now provides a downward resisting force against the upward compression force, in addition to the resistance provided against the out-of-plane force. In these cases, the partitions with the end panels 20 are slotted to fit into the cross panels 10 from below, as shown in the figures. This configuration helps distribute the compression force over all the subcomponents contacting the top of the container.
The end panels, which provide the majority of the tearing and crushing resistance of the partition set according to the present invention, can be reinforced to provide even further support. For example, varnish, paint, tape, glue and the like and combinations thereof can be added around the hand holes on the end panel. Additionally or alternatively, low adhesive glue, such as low-tack, pressure-sensitive glue, such as that used in Post-It notes, can be applied to the outside surface of the end panels. When the container handles are gripped, the increased pressure causes the glued panels to adhere to the container and prevent slipping. The low-tackiness of the glue allows the subcomponents to be stacked, yet easily separable.
The present invention can be used in a variety of containers where the handles are subject to failure. For example, as shown in
The present invention also provides additional support when the containers are stacked. The hand holes greatly reduce the compression support of the end panel directly beneath and above them, sometimes resulting in crushing of the area above the hand hole. The present invention provides additional support to prevent this crushing.
The present invention is designed and configured to provide support for standard hand holes for cardboard box containers and also for containers and end panels with diverse sizes and configurations. For example, the hand holes can be a multiplicity of finger holes 90, as shown in
Certain task may require additional reinforcement. In those cases, the present invention provides several embodiments.
Another embodiment that provides user comfort and additional reinforcement is shown in
Certain modifications and improvements will occur to those skilled in the art upon a reading of the foregoing description. The above-mentioned examples are provided to serve the purpose of clarifying the aspects of the invention and it will be apparent to one skilled in the art that they do not serve to limit the scope of the invention. All modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the present invention.
