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

Claim 11
Dependent Claim
22 words
A spacer according to claim 1, wherein the intermediate portion is at a substantially right angle to the plane of said spacer.
Claim 12
Dependent Claim
21 words
A spacer according to claim 10, wherein the flexible end portion is at a substantially right angle to said intermediate portion.
Claim 13
Dependent Claim
113 words
In combination with a container, a resilient spacer selectively applied to the surfaces of a packaged article to cushion and space same during handling, said resilient spacer comprising an integral plurality of resilient wedge-shaped elements positioned in substantially the same plane, said spacer being removably positioned against a wall of said container by means of an integral flexible tab means by insertion of said tab means into a slit in said container wall, said flexible tab means comprising an integral resilient intermediate portion in registration with said slit in said container wall, said resilient intermediate portion integrally communicating with a flexible end portion which removably retains said resilient spacer against said container wall.
Claim 14
Dependent Claim
113 words
