Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
240 words
A rapidly opening sterilizable sealed package for wound dressing adhesive tape comprising: an unfolded adhesive support carrying a wound dressing pad midway on one side thereof; a pair of protecting films applied to one side of said adhesive support in opposed positions along the length thereof so as to meet substantially centrally over said wound dressing pad where they are separated from one another and have folded-back laps; and a first pair of outer sheaths overlying and attached to said pair of protecting films, at least one of which has a folded-back portion adhesively attached to one of said folded-back laps of said protecting films and the other of which is adhesively attached to the folded back lap of the other of said protecting films, said sheaths being separably adhesively attached to one another in a position adjacent and on said one side of said wound dressing pad, a second pair of outer sheaths coextensive with said first pair of outer sheaths on the other opposite side of said adhesive support, said second pair of outer sheaths being firmly secured to said first pair of outer sheaths at respective free ends thereof remote from said wound dressing pad so as to form gripping extensons, which when pulled apart in opposite directions, cause said outer sheaths to separate centrally and in their outward movement away from one another will also move said protecting films outwardly to uncover said wound dressing pad.

A rapidly opening sterilizable sealed package for wound dressing adhesive tape comprising: an unfolded adhesive support carrying a wound dressing pad midway on one side thereof; a pair of protecting films applied to one side of said adhesive support in opposed positions along the length thereof so as to meet substantially centrally over said wound dressing pad where they are separated from one another and have folded-back laps; and a first pair of outer sheaths overlying and attached to said pair of protecting films, at least one of which has a folded-back portion adhesively attached to one of said folded-back laps of said protecting films and the other of which is adhesively attached to the folded back lap of the other of said protecting films, said sheaths being separably adhesively attached to one another in a position adjacent and on said one side of said wound dressing pad, a second pair of outer sheaths coextensive with said first pair of outer sheaths on the other opposite side of said adhesive support, said second pair of outer sheaths being firmly secured to said first pair of outer sheaths at respective free ends thereof remote from said wound dressing pad so as to form gripping extensons, which when pulled apart in opposite directions, cause said outer sheaths to separate centrally and in their outward movement away from one another will also move said protecting films outwardly to uncover said wound dressing pad.
Claim 3
Dependent Claim
163 words
A rapidly opening sterilizable sealed package as claimed in claim 1, wherein said first and second pairs of outer sheaths are formed by four strips of material extending longitudinally of said package one above and one below said wound dressing pad, said pair extending above said wound dressing pad having a portion coated with adhesive on their ends and sides directed toward the inside of the package, and being sealed together peripherally of said wound dressing pad, each of said four strips having a folded strip having a folded-back portion also coated with adhesive facing a similar folded-back portion coated with adhesive on the adjacent strip in the longitudinal direction of said package, said adhesive folded-back portions being sealed together with slight overlap so as to offer little resistance to pulling them apart in the longitudinal direction of said package, said resistance being less than the resistance offered by said portion coated with adhesive of said strips located above said wound dressing pad.
Claim 4
Dependent Claim
68 words
A rapidly opening sterilizable sealed package as claimed in claim 1, wherein said first and second pair of outer sheaths are formed by two strips of material coated with adhesive at their inner ends on their sides directed toward the inside of the package, placed one above and one below said wound dressing pad, sealed together peripherally of said wound dressing pad and having an intermediate weakened portion.
Claim 5
Dependent Claim
35 words
A rapidly opening sterilizable sealed package as claimed in claim 3, wherein a strip of sealing adhesive material is applied inwardly of said weakened portion for connection to said folded-back laps of said protecting films.
Claim 6
Dependent Claim
26 words
A rapidly opening sterilizable sealed package as claimed in claim 1, wherein said folded-back laps of said protecting films are formed by extensions of the latter.
Claim 7
Dependent Claim
29 words
A rapidly opening sterilizable sealed package as claimed in claim 1, wherein said folded-back laps of said protecting films are formed by separate elements applied to said protecting films.
Claim 8
Dependent Claim
75 words
A rapidly opening sterilizable sealed package as claimed in claim 1, wherein said folded-back laps of said protecting films are made of one strip of material having applied to the central portion thereof another narrower strip, these two strips being connected to one another by a pair of adjacent parallel transverse welding seams and then cut transversely in the area between said welding seams so as to form said folded-back laps on said protecting films.
Claim 9
Dependent Claim
31 words
A rapidly opening sterilizable sealed package as claimed in claim 1, wherein said folded-back laps of said protecting films are sealed to the adjacent portions of said outer sheaths by adhesive.
Claim 10
Dependent Claim
38 words
A rapidly opening sterilizable sealed package as claimed in claim 1, wherein said folded-back laps of said protecting films are sealed to the adjacent portions of said outer sheaths by a material made adhesive by exerting pressure thereon.
Claim 11
Dependent Claim
39 words
A rapidly opening sterilizable sealed package as claimed in claim 1, wherein said folded-back laps of said protecting films are sealed to the adjacent portions of said outer sheaths by a material made adhesive under the influence of heat.
Claim 12
Dependent Claim
66 words
A rapidly opening sterilizable sealed package as claimed in claim 1, wherein the central adjacent ends of said protecting films may be secured to the adjacent portions of said first pair of outer sheaths by any conventional process compatible with the material of the parts to be connected and ensuring adequate resistance of the thus connected parts to a force tending to pull those parts apart.
