Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 64 words
An improved meat package, said package comprising: a meat item encased in a wrapper, said meat item having surface area potentially capable of puncturing said wrapper; and a cushion film interposed between said surface areas and said wrapper, said cushion film comprising a layer of flexible and resilient foam material and an oxygen impermeable surface covering disposed between said layer and said surface areas.
Claim 2
Dependent Claim 64 words
An improved meat package, said package comprising: a meat item encased in a wrapper, said meat item having surface area potentially capable of puncturing said wrapper; and a cushion film interposed between said surface areas and said wrapper, said cushion film comprising a layer of flexible and resilient foam material and an oxygen impermeable surface covering disposed between said layer and said surface areas.
Claim 3
Dependent Claim 18 words
The package of claim 1 wherein said cushion film includes a layer of foam about 1/16-1/8 inch thick.
Claim 4
Dependent Claim 28 words
The package of claim 1 wherein said cushion film includes a surface covering that is a separate film that is bonded to a surface of said foam material.
Claim 5
Dependent Claim 30 words
The package of claim 1 wherein the resilient foam material is capable of absorbing or adsorbing at least a quantity of liquid that may be released from said meat portion.
Claim 6
Dependent Claim 30 words
The package of claim 1 wherein the package is evacuated and said oxygen impermeable surface covering prevents oxygen in said foam material from contacting the meat surface areas covered thereby.
Claim 7
Dependent Claim 27 words
The package of claim 1 wherein said cushion film includes an oxygen impervious foam material and said surface covering is a continuous film of the same material.
Claim 8
Dependent Claim 22 words
The package of claim 1 wherein said cushion film has a surface covering that extends beyond the edges of said foam layer.
Claim 9
Dependent Claim 20 words
The package of claim 1 wherein at least one surface of said cushion film is coated with a non-toxic adhesive.
Claim 10
Dependent Claim 20 words
The package of claim 8 wherein the non-toxic adhesive is coated on the meat contacting surface of said surface covering.
Claim 11
Dependent Claim 97 words
An improved meat package, said package comprising: a meat item completely encased in a wrapper, said meat item having surface areas potentially capable of puncturing said wrapper; and a cushion film in contact with and interposed between said surface areas and said wrapper, said cushion film comprising a layer of a flexible and resilient liquid absorptive or adsorptive foam material and an oxygen impermeable surface covering disposed between said layer and said surface areas said layer of a foam material being accessible to any free liquid that may be retained between said wrapper and said meat surface.
Claim 12
Dependent Claim 97 words
An improved meat package, said package comprising: a meat item completely encased in a wrapper, said meat item having surface areas potentially capable of puncturing said wrapper; and a cushion film in contact with and interposed between said surface areas and said wrapper, said cushion film comprising a layer of a flexible and resilient liquid absorptive or adsorptive foam material and an oxygen impermeable surface covering disposed between said layer and said surface areas said layer of a foam material being accessible to any free liquid that may be retained between said wrapper and said meat surface.
Claim 13
Dependent Claim 75 words
An improved method of packaging meat items so as to prevent the puncturing of a wrapper, said method comprising: placing a cushion film across surface areas of a meat item that could potentially puncture a wrapper, said cushion film comprising a layer of a flexible and resilient foam material and an oxygen impermeable surface covering disposed between said foam and said surface areas; and enwrapping said meat, item and said cushion film with a wrapper.
Claim 14
Dependent Claim 75 words
An improved method of packaging meat items so as to prevent the puncturing of a wrapper, said method comprising: placing a cushion film across surface areas of a meat item that could potentially puncture a wrapper, said cushion film comprising a layer of a flexible and resilient foam material and an oxygen impermeable surface covering disposed between said foam and said surface areas; and enwrapping said meat, item and said cushion film with a wrapper.
Claim 15
Dependent Claim 29 words
The method of claim 11 wherein the resilient foam material is capable of absorbing or adsorbing at least a quantity of liquid may be released from said meat item.
Claim 16
Dependent Claim 17 words
The method of claim 11 wherein the space between said wrapper and said meat items is evacuated.
Claim 17
Dependent Claim 25 words
The method of claim 13 wherein said oxygen impermeable surface covering prevents oxygen in said foam material from contacting the meat surface areas covered thereby.
Claim 18
Dependent Claim 76 words
The method of claim 11 wherein at lease one surface of said cushion film is coated with a non-toxic adhesive, and said cushion film and surface covering are folded and overlapped to conform closely with the meat surface areas to be protected against wrapper puncture whereby said adhesive coated portions of said cushion film will adhere together so as to hold said cushion film against the contours of said meat surface areas during said enwrapping step.
Claim 19
Dependent Claim 20 words
The method of claim 15 wherein said non-toxic adhesive is coated on the meat contacting surface of said surface covering.
Claim 20
Dependent Claim 101 words
An improved method for packaging meat items so as to prevent the puncturing of a wrapper, said method comprising: placing a cushion film across surface areas of a meat item that could potentially puncture a wrapper, said cushion film comprising a layer of flexible and resilient liquid absorptive or adsorptive foam material and an oxygen impermeable surface covering disposed between said foam and said surface areas, said layer of foam material being accessible to any free liquid that may be retained between said wrapper and said meat surface, and completely enwrapping said meat items and said cushion film with a wrapper.
Claim 21
Dependent Claim 101 words
An improved method for packaging meat items so as to prevent the puncturing of a wrapper, said method comprising: placing a cushion film across surface areas of a meat item that could potentially puncture a wrapper, said cushion film comprising a layer of flexible and resilient liquid absorptive or adsorptive foam material and an oxygen impermeable surface covering disposed between said foam and said surface areas, said layer of foam material being accessible to any free liquid that may be retained between said wrapper and said meat surface, and completely enwrapping said meat items and said cushion film with a wrapper.
