Abstract
Abstract This disclosure relates to a tear-away tab or closure for cans, in which, the tear-away closure is retained on the can. The top of the can is formed with a tab defined by a scored segment extending radially from approximately the center of the top to the rim of the can. A stem overlying the tab is secured to the inner end of the tab and extends along the tab towards the rim of the can. A pulling ring overlies the stem and is secured to the outer end of the stem. The can is opened by lifting the ring upwardly and pulling the stem to a generally vertical position over the inner end of the tab, then forcing the stem and ring downwardly so that the tab will break away from the can top along the scored edges to form the opening in the can. The outer end of the tab is not scored, and thus remains attached to the top when the can is opened.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
96 words
A tear-away tab device within a container wall for providing an opening in said container wall comprising: a. tab means in said container wall adapted to be partially severed from said container wall, thereby forming said opening in said container wall; b. stem means secured to said tab means and adapted to apply pressure to said tab means to sever said tab means from said container wall and force said tab means into the container; and c. handle means secured to said stem means for manipulating said stem means to apply pressure on said tab means.
Claim 2
Dependent Claim
96 words
A tear-away tab device within a container wall for providing an opening in said container wall comprising: a. tab means in said container wall adapted to be partially severed from said container wall, thereby forming said opening in said container wall; b. stem means secured to said tab means and adapted to apply pressure to said tab means to sever said tab means from said container wall and force said tab means into the container; and c. handle means secured to said stem means for manipulating said stem means to apply pressure on said tab means.
Claim 3
Dependent Claim
62 words
The tear-away tab device of claim 1, wherein said tab means is a closure strip defined by a scored line which partially encloses said closure strip and a bend line between the ends of said scored line, said closure strip can be severed from said container wall along said scored line while remaining attached to said container wall along said bend line.
Claim 4
Dependent Claim
54 words
The tear-away tab device of claim 1, wherein said stem means is an elongated member which overlies said tab means and which can be manipulated by an initial upward and subsequent downward force applied to said handle means so that said tab means is severed from said container wall and forced into said container.
Claim 5
Dependent Claim
56 words
The tear-away tab device of claim 1, wherein said handle means is a pull ring which overlies both said tab and stem means, said pull ring being adapted to manipulate said stem in order to force said tab means into said container upon an initial upward and subsequent downward force being applied to said pull ring.
Claim 6
Dependent Claim
54 words
The tear-away tab device of claim 2, wherein said stem means is an elongated member which overlies said closure strip and which can be manipulated by an initial upward and subsequent downward force applied to said handle means so that said closure strip is severed from said container wall and forced into said container.
Claim 7
Dependent Claim
57 words
The tear-away strip of claim 5, wherein said handle means is a pull ring which overlies both said closure strip and said elongated member, said pull ring being adapted to manipulate said stem in order to force said closure strip into said container upon an initial upward and subsequent downward force being applied to said pull ring.
Claim 8
Dependent Claim
118 words
The tear-away strip of claim 1, wherein said stem means is an elongated member overlying said tab means, said elongated member having a first crease line dividing said member into a first and second portion, said first portion being secured to said handle means, said second portion being secured to said tab means so that said elongated member applies pressure to said tab means and severs the tab means from said container wall and forces said tab inwardly when said elongated member is bent along said first crease line so that said second portion of said elongated member is rotated to a vertical position by applying an initial upward force and subsequent downward force to said handle means.
Claim 9
Dependent Claim
97 words
The tear away tab device of claim 7, wherein said handle means is a pull ring overlying both said tab means and said elongated member, said pulling ring haVing a base portion divided into a first and second section by a second crease line, said first section being secured to said elongated member and said second section being integrally formed with a finger ring, said second section and said finger ring being adapted to pivot upwardly with respect to said first section about said second crease line when said upward force is applied to said pull ring.
Claim 10
Dependent Claim
123 words
The tear-away tab device of claim 2, wherein said stem means is an elongated member overlying said closure strip, said elongated member having a first crease line dividing said member into a first and second portion, said first portion, said first portion being secured to said handle means, said second portion being secured to said closure strip so that said elongated member applies pressure to said closure strip and severs said closure strip from said container wall and forces said closure strip inwardly when said elongated member is bent along said first crease line so that said second portion of said elongated member is rotated to a vertical position by applying an initial upward force and subsequent downward force to said handle means.
Claim 11
Dependent Claim
96 words
The tear-away tab device of claim, 9 wherein said handle means is a pull ring overlying both said closure strip and said elongated member, said pulling ring having a base portion divided into a first and second section by a second crease line, said first section being secured to said elongated member and said second section being integrally formed with a finger ring, said second section and said finger ring being adapted to pivot upwardly with respect to said first section about said second crease line when said upward force is applied to said pull ring.
