Abstract
Abstract A breather package for surgical elements such as sutures or suture-needle assemblies having a layer of fibrous material and a layer of plastic material forming a pocket therebetween. Longitudinal heat seals and transverse top and bottom seals are provided which form the package. The layer of fibrous material is provided with longitudinal strips of release agent material through which the longitudinal heat seals are formed. An apparatus for forming such a package is also disclosed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
205 words
A method for packaging surgical elements, said method comprising: providing a web of fibrous material in sheet form, said web having a release agent applied thereon in at least two continuous longitudinal strips, said strips beginning at a first longitudinal edge of web material and being spaced at regular identical intervals across said web, said strips ending at a second longitudinal edge of said web; providing a web of plastic material having substantially the same width as said web of fibrous material; forming rows of recesses in said plastic material at regular intervals for accepting surgical elements to be packaged; advancing said plastic web; placing said surgical elements at regular intervals in said recesses; advancing said fibrous web into overlying relation with said plastic web, said surgical elements being disposed between said webs, said recesses in said plastic web being aligned between said release agent strips; activating said release agent to releasably secure said plastic web to said fibrous web longitudinally along each of said release agent strips; heat sealing said plastic web directly to said fibrous web transversely from said first longitudinal edge to said second longitudinal edge to enclose surgical elements individually; and cutting said webs at said seals to form individual packages.
Claim 2
Independent Claim
205 words
A method for packaging surgical elements, said method comprising: providing a web of fibrous material in sheet form, said web having a release agent applied thereon in at least two continuous longitudinal strips, said strips beginning at a first longitudinal edge of web material and being spaced at regular identical intervals across said web, said strips ending at a second longitudinal edge of said web; providing a web of plastic material having substantially the same width as said web of fibrous material; forming rows of recesses in said plastic material at regular intervals for accepting surgical elements to be packaged; advancing said plastic web; placing said surgical elements at regular intervals in said recesses; advancing said fibrous web into overlying relation with said plastic web, said surgical elements being disposed between said webs, said recesses in said plastic web being aligned between said release agent strips; activating said release agent to releasably secure said plastic web to said fibrous web longitudinally along each of said release agent strips; heat sealing said plastic web directly to said fibrous web transversely from said first longitudinal edge to said second longitudinal edge to enclose surgical elements individually; and cutting said webs at said seals to form individual packages.
Claim 3
Dependent Claim
13 words
A method according to claim 1, wherein said surgical elements comprise suture-needle assemblies.
Claim 4
Dependent Claim
21 words
A method according to claim 1, wherein said step of forming recesses in said plastic web comprises vacuum forming said recesses.
Claim 5
Dependent Claim
82 words
A method according to claim 1, wherein said webs are cut along said longitudinal seals whereby said plastic layer is secured to said fibrous layer at said release agent, and along said transverse heat seals whereby said plastic layer is secured directly to said fibrous layer, and further wherein said transverse top edge seal is spaced from said top edge so as to define a gripping tab to facilitate separation of said plastic layer from said fibrous layer to open said package.
Claim 6
Dependent Claim
35 words
A method according to claim 1, further comprising the step of applying said release agent to said fibrous web in a plurality of strips, said recesses on said plastic web being positioned between said strips.
Claim 7
Independent Claim
115 words
A method for packaging surgical elements, comprising: positioning ga web of fibrous material adjacent to a web of plastic material, said fibrous web having at least two continuous strips of a release agent applied thereon and spatially positioned to define sides of individual packages, said plastic material having recesses formed therein to coincide with said spacing between said at least two strips; placing said surgical elements in said recesses; activating said release agent to releasably secure said plastic web to said fibrous web along said sides; heat sealing said fibrous web directly to said plastic web along said top and bottom edges traverse to said sides; and scoring said sealed webs to form individual packages.
Claim 8
Independent Claim
115 words
A method for packaging surgical elements, comprising: positioning ga web of fibrous material adjacent to a web of plastic material, said fibrous web having at least two continuous strips of a release agent applied thereon and spatially positioned to define sides of individual packages, said plastic material having recesses formed therein to coincide with said spacing between said at least two strips; placing said surgical elements in said recesses; activating said release agent to releasably secure said plastic web to said fibrous web along said sides; heat sealing said fibrous web directly to said plastic web along said top and bottom edges traverse to said sides; and scoring said sealed webs to form individual packages.
Claim 9
Dependent Claim
15 words
A method according to claim 6, wherein said heat sealed surgical elements comprise suture-needle assemblies.
Claim 10
Dependent Claim
86 words
A method according to claim 6, wherein said webs are scored along said longitudinal seals whereby said plastic web is secured to said fibrous web at said release agent, and along said transverse heat seals whereby said plastic web is secured directly to said fibrous web, and further wherein said transverse top edge seal is spaced from a top edge of said individual package so as to define a gripping tab to facilitate separation of said plastic web from said fibrous web to open said package.
Claim 11
Dependent Claim
32 words
A method according to claim 6, wherein scoring said sealed webs comprises traversely and horizontally cutting said sealed webs to separate adjacent packages at transverse and longitudinal seals to form individual packages.
