Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 122 words
A package for a sterilized product comprising a container made of a plastic material, said container consisting of overlying front and rear panels, the front panel having upper and lower sections adjacent confronting edges of which define an access opening, said front and rear panels being joined along their open edges, an opaque tear strip over said access opening, said tear strip made of spun bond polyolefin having a heat seal waxlike coating on one face thereof confronting said front panel, said tear strip being sealed over said access opening in a predetermined controlled manner so that the seal area about the periphery of said access opening is transparent through said tear strip to provide visual indicia means of an integral seal.
Claim 2
Dependent Claim 122 words
A package for a sterilized product comprising a container made of a plastic material, said container consisting of overlying front and rear panels, the front panel having upper and lower sections adjacent confronting edges of which define an access opening, said front and rear panels being joined along their open edges, an opaque tear strip over said access opening, said tear strip made of spun bond polyolefin having a heat seal waxlike coating on one face thereof confronting said front panel, said tear strip being sealed over said access opening in a predetermined controlled manner so that the seal area about the periphery of said access opening is transparent through said tear strip to provide visual indicia means of an integral seal.
Claim 3
Dependent Claim 28 words
A package as claimed in claim 1 wherein tHe upper section of the front panel is formed integrally with the rear panel along an upper transverse fold line.
Claim 4
Dependent Claim 22 words
A package as claimed in claim 1 wherein the front and rear panels are joined by means of a double seal arrangement.
Claim 5
Dependent Claim 39 words
A package as claimed in claim 1 wherein the front and rear panels are generally rectangular and said rear panel has a flap extension with openings therein to facilitate loading on a wicket where the packages may be filled.
Claim 6
Dependent Claim 26 words
A package as claimed in claim 1 wherein the seal areas extending the length of said access opening are spaced therefrom to define a sterile zone.
Claim 7
Dependent Claim 37 words
A package as claimed in claim 1 wherein the seal areas extending lengthwise of said access opening are spaced inwardly from the opposed edges of said tear strip to define tabs facilitating removal of said tear strip.
Claim 8
Dependent Claim 196 words
A package for a sterilized product comprising a container made of a plastic material, said container consisting of overlying front and rear panels, the front panel having upper and lower sections adjacent confronting edges of which define an access opening, said front and rear panels being joined along their open edges, an opaque tear strip over said access opening, said tear strip made of spun bond polyolefin having a heat seal waxlike coating on one face thereof confronting said front panel, said tear strip being sealed over said access opening in a predetermined controlled manner so that the seal area about the periphery of said access opening is transparent through said tear strip to provide visual indicia means of an integral seal, the seal areas extending the length of said access opening being spaced therefrom to define a sterile zone and said product being disposed in the lower portion of said package with the upper edge generally aligned with the access opening whereby upon removal of said tear strip the upper section of said package may be folded to expose the product through said access opening thereby providing a sterile field for delivery of the product.
