Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 134 words
A container for packaging meat articles having protruding bone sections therein, comprising: a body portion of flexible material having two sides which merge at one end of the body portion to define a closed end and which define a single opening located opposite said closed end, said body portion being capable of enveloping one of said articles; and a layer of material more puncture resistant than said flexible material disposed within said body portion and being attached to one of said sides adjacent said opening and being unattached adjacent said closed end and terminating adjacent said closed end such that the area between said layer and said one of said sides is in fluid communication with said single opening, through said unattached part of said layer, said layer having a plurality of apertures therethrough.
Claim 2
Dependent Claim 134 words
A container for packaging meat articles having protruding bone sections therein, comprising: a body portion of flexible material having two sides which merge at one end of the body portion to define a closed end and which define a single opening located opposite said closed end, said body portion being capable of enveloping one of said articles; and a layer of material more puncture resistant than said flexible material disposed within said body portion and being attached to one of said sides adjacent said opening and being unattached adjacent said closed end and terminating adjacent said closed end such that the area between said layer and said one of said sides is in fluid communication with said single opening, through said unattached part of said layer, said layer having a plurality of apertures therethrough.
Claim 3
Dependent Claim 19 words
The container according to claim 1 wherein said layer is disposed on a single side of said body portion.
Claim 4
Dependent Claim 25 words
The container according to claim 1 wherein said sides communicate at edges and said layer is heat sealed to said body portion at said edges.
Claim 5
Dependent Claim 49 words
The container according to claim 1 wherein said layer is substantially rectangular in shape and is heat sealed along three of its edges to said body portion and the fourth edge is disposed at said one end of said container substantially oppositely disposed from said opening of said container.
Claim 6
Dependent Claim 14 words
The container according to claim 1 wherein said flexible packaging material is heat shrinkable.
Claim 7
Dependent Claim 21 words
The container according to claim 1 further comprising a self welding material disposed on said layer of more puncture resistant material.

Claim 9
Dependent Claim 136 words
A process for packaging meat articles having protruding bone sections therein, comprising: enveloping said meat article with a container, said container comprising; a body portion of a flexible material having two sides which merge at one end of the body portion to define a closed end and which define a single opening located opposite said closed end and a layer of perforated material more puncture resistant than said body portion disposed between said sides and being attached to one of said sides adjacent said opening and being unattached adjacent said closed end such that the area between said layer and said one of said sides is in fluid communication with said single opening through said unattached part of said layer, said layer having a plurality of apertures therethrough, and said layer overlying said protruding bone sections.
Claim 10
Dependent Claim 136 words
A process for packaging meat articles having protruding bone sections therein, comprising: enveloping said meat article with a container, said container comprising; a body portion of a flexible material having two sides which merge at one end of the body portion to define a closed end and which define a single opening located opposite said closed end and a layer of perforated material more puncture resistant than said body portion disposed between said sides and being attached to one of said sides adjacent said opening and being unattached adjacent said closed end such that the area between said layer and said one of said sides is in fluid communication with said single opening through said unattached part of said layer, said layer having a plurality of apertures therethrough, and said layer overlying said protruding bone sections.
Claim 11
Dependent Claim 53 words
The process according to claim 8 further comprising: evacuating said container; closing said container whereby said meat article is disposed within the evacuated container; and heating said container to shrink said container about said meat article with said layer overlying said bone sections to protect said body portion from the protruding bone portion.
