Abstract
Abstract A leader on a web coacts with a hook which projects into a reel chamber in a case to limit web recoil into, and interfere with initiation of web removal from, the case. The leader also coacts with a reel on which the web is wound to prevent web ravel. The leader has an aperture and is fashioned with a pair of sloping shoulders which are wider than the spacing of the reel flanges such that upon web recoil the shoulders engage the flanges causing the leader to bend and displace the aperture toward engagement with the hook and to tension the reel to cause its frictional retention.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
87 words
A cartridge comprising: a case having a chamber with an opening to the exterior; a reel with a hub mounted for roTation in said chamber; a web coiled about said hub for removal from and return to for recoiling in said chamber through said opening and having a lead end portion; a leader mounted on said lead end portion and having an aperture extending therethrough, and a hook arranged from said case for engaging in said aperture to limit movement of said web in a recoiling direction.
Claim 2
Dependent Claim
87 words
A cartridge comprising: a case having a chamber with an opening to the exterior; a reel with a hub mounted for roTation in said chamber; a web coiled about said hub for removal from and return to for recoiling in said chamber through said opening and having a lead end portion; a leader mounted on said lead end portion and having an aperture extending therethrough, and a hook arranged from said case for engaging in said aperture to limit movement of said web in a recoiling direction.
Claim 3
Dependent Claim
29 words
A combination according to claim 1 characterized by means for displacing said aperture toward engagement with said hook as the lead end portion is moved in a recoiling direction.
Claim 4
Dependent Claim
32 words
A combination according to claim 2 wherein said hook is disposed in said chamber and provides a bearing surface over which said web travels during removal from and return to said chamber.
Claim 5
Dependent Claim
46 words
A combination according to claim 2 wherein said displacing means comprises a pair of spaced apart reel flanges between which said web is coiled about said hub and means on said leader for engaging said flanges after said lead end portion is returned to said chamber.
Claim 6
Dependent Claim
43 words
A combination according to claim 4 wherein said engaging means comprises a pair of opposed marginal side portions of said leader having a width greater than the width of said web and flanges for engaging said flanges upon recoil movement of said web.
Claim 7
Dependent Claim
30 words
A combination according to claim 5 wherein said marginal side portions have a pair of tapered shoulders comprising elements of said leader for first engaging said flanges during recoil movement.
Claim 8
Dependent Claim
36 words
A combination according to claim 5 wherein said case has a pair of parallel side walls, said hook is disposed midway between said side walls and said aperture is centered with respect to said side portions.
Claim 9
Dependent Claim
40 words
A combination according to claim 1 wherein the leader has a portion projecting from said case following limitation of web movement and characterized in that said case has an external slot spaced from said opening for removably receiving said portion.
Claim 10
Dependent Claim
32 words
A combination according to claim 1 wherein said hook is fashioned for frictionally engaging and releasably holding said leader to interfere with initiation of web removal from said case through said opening.
Claim 11
Dependent Claim
94 words
In a case of the type having a pair of connected together case sections defining a reel chamber and adapted for recoilably dispensing a web from said chamber through a case opening, and having a hook projecting into said chamber for engaging in a web aperture to limit web movement in a recoil direction, the improvement comprising a pair of spaced apart wall segments perimetrically limiting said reel chamber, said segments being integral with, spaced from, and defining a socket within said case outside of said reel chamber for receiving and holding said hook.
Claim 12
Dependent Claim
94 words
In a case of the type having a pair of connected together case sections defining a reel chamber and adapted for recoilably dispensing a web from said chamber through a case opening, and having a hook projecting into said chamber for engaging in a web aperture to limit web movement in a recoil direction, the improvement comprising a pair of spaced apart wall segments perimetrically limiting said reel chamber, said segments being integral with, spaced from, and defining a socket within said case outside of said reel chamber for receiving and holding said hook.
Claim 13
Dependent Claim
124 words
In a web of the type adapted for storage in a coil on a flanged reel in a case and having a leader mounted on its lead end portion for facilitating removal of said web from said case, the improvement characterized in that said leader is wider than said web for engaging the flanges of said reel when said tape is recoiled on said reel following removal therefrom, said leader has a trail end portion proximate said web, said trail end portion having a pair of sloping shoulders proportioned for engaging the flanges of said reel upon web recoil, and said leader has an aperture proportioned to cause said leader to bend transversely of said web when said shoulders are drawn into flange engagement.
Claim 14
Dependent Claim
124 words
In a web of the type adapted for storage in a coil on a flanged reel in a case and having a leader mounted on its lead end portion for facilitating removal of said web from said case, the improvement characterized in that said leader is wider than said web for engaging the flanges of said reel when said tape is recoiled on said reel following removal therefrom, said leader has a trail end portion proximate said web, said trail end portion having a pair of sloping shoulders proportioned for engaging the flanges of said reel upon web recoil, and said leader has an aperture proportioned to cause said leader to bend transversely of said web when said shoulders are drawn into flange engagement.
Claim 15
Dependent Claim
94 words
A cartridge comprising: a case having a chamber therein with an opening to the exterior; a reel with a hub and a pair of spaced apart radial flanges mounted for rotation and radial shifting in said chamber; a web having a trail end portion connected to said reel and arranged for passing through said opening in dispensing and recoiling directions; and a leader on said web proportioned for tensioning said web and radially shifting and frictionally immobilizing said reel when said web is recoiled about said hub to prevent web ravel in said case.
Claim 16
Dependent Claim
94 words
A cartridge comprising: a case having a chamber therein with an opening to the exterior; a reel with a hub and a pair of spaced apart radial flanges mounted for rotation and radial shifting in said chamber; a web having a trail end portion connected to said reel and arranged for passing through said opening in dispensing and recoiling directions; and a leader on said web proportioned for tensioning said web and radially shifting and frictionally immobilizing said reel when said web is recoiled about said hub to prevent web ravel in said case.
Claim 17
Dependent Claim
37 words
A combination according to claim 12 wherein said hub has an opening and characterized by a pin fixed to said case and disposed in said opening for frictionally restraining said hub when said reel is radially shifted.
Claim 18
Dependent Claim
35 words
A combination according to claim 13 wherein said leader is wider than the spacing of said flanges for engaging and tensioning said reel against said pin while said web is moved in a recoil direction.
