Problems solved by technology

Unfortunately, it requires the use of plastic sheeting, which is less ecologically friendly than the corrugated containerboard.
And unfortunately, the use of the plastic sheeting raises manufacturing costs not only in materials but also in assembly.

Embodiment Construction

[0016]The invention will be understood more fully from the detailed description given below and from the accompanying drawings of embodiments of the invention which, however, should not be taken to limit the invention to the specific embodiments described, but are for explanation and understanding only.

[0017]FIG. 1 with detail view IA illustrates one embodiment of a suspension frame 10 which may be used in practicing the principles of this invention. The suspension frame may advantageously be formed from a single sheet of corrugated containerboard, with its features being formed by die cutting. The suspension frame includes an article platform portion 12 which may in some embodiments be located generally in a center of the suspension frame. The suspension frame also includes a perimeter portion 14 which will define a mating face of the suspension frame, and sidewall portions 16 which will be folded during the assembly process to give the suspension frame a 3-D shape providing depth ...

Abstract

An improved suspension package system in which one or more suspension frames are used to suspend an article within a shipping container, wherein the suspension frame includes a suspension mechanism formed by a plurality of generally concentric cuts forming a plurality of suspension channel members, each cut being interrupted by one or more nicks. The nicks conjoin adjacent channel members, and conjoin an innermost channel member to an optional article platform, and conjoin an outermost channel member to an optional perimeter portion. Sidewalls give the suspension frame a 3-D shape and provide suspension clearance. The article can be sandwiched between two opposing suspension frames. The suspension frame can be formed as a monolithic piece of corrugated containerboard. Forming the suspension of corrugated containerboard improves the recyclability of the product, and reduces its manufacturing cost by eliminating the need for purchasing and assembling a plastic suspension sheet. The frame can also be configured as a retention frame.

Description

BACKGROUND OF THE INVENTION [0001]1. Technical Field of the Invention[0002]This invention relates generally to shipment packaging, and more specifically to packaging formed of corrugated containerboard, folding carton stock, paperboard, or the like, having an improved means of suspending or retaining articles packaged therein.[0003]2. Background Art[0004]U.S. Pat. No. 5,388,701 “Suspension Packaging” by Devin C. Ridgeway and assigned to Sealed Air Corp. teaches a suspension packaging system in which two suspension frames are disposed within a corrugated containerboard box. Each suspension frame includes a corrugated containerboard frame to which is affixed a resilient member formed of a sheet of plastic. The suspension frames are placed one atop the other, with their plastic sheets adjacent each other, and the packaged article is suspended between the plastic sheets. The resiliency of the plastic sheets provides the suspension characteristic of the packaging, and allows the packaged...
