Abstract
Abstract A resilient packaging spacer is provided comprising a plurality of flexible joined triangular or wedge-shaped elements, positioned in the same plane, said spacer being equipped with flexible insert means for attaching the spacer through a slit in a carton, such as a paperboard container. The resilient packaging spacer is intended to space cylindrical rectangular or squareshaped articles, such as a water heater, etc., in a container. For packaging cylindrical articles, the intermediate wedge-shaped elements are shorter than the exterior or terminal elements.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
108 words
A resilient spacer adapted to be selectively applied to the surfaces of an article to be packaged to cushion and space same during handling, comprising an integral plurality of resilient wedge-shaped elements positioned in substantially the same plane, said spacer being equipped with a flexible tab means to removably position said spacer on the wall of a container by insertion into a slit in said container wall, said flexible tab means comprising an integral resilient intermediate portion to register with a slit in said container wall, said resilient intermediate portion integrally communicating with a flexible end portion capable of removably retaining said resilient spacer against said container wall.
Claim 2
Dependent Claim
108 words
A resilient spacer adapted to be selectively applied to the surfaces of an article to be packaged to cushion and space same during handling, comprising an integral plurality of resilient wedge-shaped elements positioned in substantially the same plane, said spacer being equipped with a flexible tab means to removably position said spacer on the wall of a container by insertion into a slit in said container wall, said flexible tab means comprising an integral resilient intermediate portion to register with a slit in said container wall, said resilient intermediate portion integrally communicating with a flexible end portion capable of removably retaining said resilient spacer against said container wall.
Claim 3
Dependent Claim
23 words
A spacer according to claim 1, wherein the flexible tab means are strips at each end of a row of said wedge-shaped elements.
Claim 4
Dependent Claim
25 words
A spacer according to claim 1, wherein the flexible tab means is a strip applied at the side of a row of said wedge-shaped elements.
Claim 5
Dependent Claim
33 words
