Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
85 words
A sterile cover for a tube of plastic material which comprises a sheath of flexible film material disposed over and sealed about said tube by at least one peelable seal closing said sheath about said tube, said sheath having free end tabs extending about said tube, the seal being so positioned and the end tabs so constructed and arranged that when said tabs are pulled said peelable seal is progressively opened, said sheath is progressively inverted, and said inverted sheath is removed from said tube.
Claim 2
Dependent Claim
85 words
A sterile cover for a tube of plastic material which comprises a sheath of flexible film material disposed over and sealed about said tube by at least one peelable seal closing said sheath about said tube, said sheath having free end tabs extending about said tube, the seal being so positioned and the end tabs so constructed and arranged that when said tabs are pulled said peelable seal is progressively opened, said sheath is progressively inverted, and said inverted sheath is removed from said tube.
Claim 3
Dependent Claim
64 words
A cover as claimed in claim 1, in which said sheath is peelably sealed to said tube by a plurality of peelable seals disposed in spaced relationship with respect to each other, at least one of said peelable seals being a destructible sterility seal extending in a plane transverse to the longitudinal axis of said tube and circumferentially closing said sheath about said tube.
Claim 4
Dependent Claim
20 words
A cover as claimed in claim 1, in which said end tabs are sealed to each other at their extremities.
Claim 5
Dependent Claim
16 words
A cover as claimed in claim 1, in which said sheath is a single folded strip.
Claim 6
Dependent Claim
13 words
A cover as claimed in claim 1, in which said sheath is tubular.
Claim 7
Dependent Claim
24 words
A cover as claimed in claim 2, in which the peelable seals extend in a plane transverse to the longitudinal axis of the tube.
Claim 8
Dependent Claim
24 words
A cover as claimed in claim 2, in which the peelable seals extend in a plAne parallel to the longitudinal axis of the tube.
Claim 9
Dependent Claim
29 words
A cover as claimed in claim 2, in which the tube is made of an olefin polymer and the thermoplastic film is made of an ionic ethylene-carboxylic acid copolymer.
Claim 10
Dependent Claim
17 words
A cover as claimed in claim 2, in which said sheath is composed of a film laminate.
Claim 11
Dependent Claim
61 words
A cover as claimed in claim 2, in which the tube is made of an olefin polymer and the sheath is made of a film obtained from a material selected from the group consisting of ethylene terephthalate polymer and a vinyl polymer, said film having a surface thereof in contact with the tube coated with a layer of ethylene-vinyl acetate copolymer.
Claim 12
Dependent Claim
65 words
A cover as claimed in claim 1, in which the sheath is made of a film strip selected from the group consisting of heat-shrinkable thermoplastic film and elastic film, said film having edges adhered to each other around the tube by a peelable seal and said sheath being peelably and circumferentially sealed to said tube by a peelable, destructible sterility seal transverse to the tube.
Claim 13
Dependent Claim
88 words
A sterile cover for a tube of plastic material which cover comprises a sheath of flexible film material disposed over and sealed about said tube by at least one peelable seal closing said sheath about said tube, said sheath having a free end portion extending about said tube, the seal being so positioned and the end portion so constructed and arranged that when said end portion is pulled said peelable seal is progressively opened, said sheath is progressively inverted, and said inverted sheath is removed from said tube.
Claim 14
Dependent Claim
88 words
A sterile cover for a tube of plastic material which cover comprises a sheath of flexible film material disposed over and sealed about said tube by at least one peelable seal closing said sheath about said tube, said sheath having a free end portion extending about said tube, the seal being so positioned and the end portion so constructed and arranged that when said end portion is pulled said peelable seal is progressively opened, said sheath is progressively inverted, and said inverted sheath is removed from said tube.
