Can ends with narrow scores
A can end includes a main score forming in an arcuate pattern on an upper surface of the can end. The main score defines a tear panel. An anti-fracture score is disposed parallel and contiguous with the main score. The residual thickness of material after scoring ranges between 0.0045 and 0.0057 inch.
1 . A can end comprising:
a main score disposed in an arcuate pattern on an upper surface of the can end, the main score defining a tear panel;
an anti-fracture score disposed parallel and contiguous with the main score, wherein a residual or thickness of material of scoring ranges from 0.0045 to 0.0057 inch; and
wherein the anti-fracture score has a residual or thickness of material that is greater than the main score residual.
2 . The can end of claim 1 , further comprising a shadow bead defined on the tear panel.
3 . The can end of claim 1 , wherein the can end is formed in part by a blade with a width of between 0.0002 and 0.0008 inch.
4 . The can end of claim 1 , wherein the anti-fracture score has a width of 0.0012 inch.
5 . The can end of claim 1 , wherein the anti-fracture score residual is between 0.001 and 0.003 inch higher than the main score residual.
6 . The can end of claim 1 , wherein the main score and the anti-fracture score are disposed across a relieved portion of a bubble.
7 . A can end comprising:
a main score disposed in an arcuate pattern on an upper surface of the can end, the main score defining a tear panel; and
an anti-fracture score disposed parallel and contiguous with the main score,
wherein a residual or thickness of material of scoring ranges from 0.0045 to 0.0057 inch;
wherein an anti-fracture score residual is between 0.001 and 0.003 inch higher than a main score residual.
8 . The can end of claim 7 , further comprising a shadow bead defined on the tear panel.
9 . The can end of claim 7 , wherein the can end is formed in part by a blade with a width of between 0.0002 and 0.0008 inch.
10 . The can end of claim 7 , wherein the anti-fracture score has a residual or thickness of material that is greater than the main score residual.
11 . The can end of claim 7 , wherein the main score and the anti-fracture score are disposed across a relieved portion of a bubble.
12 . The can end of claim 7 , wherein the anti-fracture score has a width of 0.0012 inch.
13 . A can end comprising:
a main score disposed in an arcuate pattern on an upper surface of the can end, the main score defining a tear panel; and
an anti-fracture score disposed parallel and contiguous with the main score,
wherein a residual or thickness of material of scoring ranges from 0.0045 to 0.0057 inch;
wherein the main score and the anti-fracture score are disposed across a relieved portion of a bubble.
14 . The can end of claim 13 , further comprising a shadow bead defined on the tear panel.
15 . The can end of claim 13 , wherein the can end is formed in part by a blade with a width of between 0.0002 and 0.0008 inch.
16 . The can end of claim 13 , wherein the anti-fracture score has a residual or thickness of material that is greater than the main score residual.
17 . The can end of claim 13 , wherein an anti-fracture score residual is between 0.001 and 0.003 inch higher than a main score residual.
18 . The can end of claim 13 , wherein the anti-fracture score has a width of 0.0012 inch.
19 . A can end comprising:
a main score disposed in an arcuate pattern on an upper surface of the can end, the main score defining a tear panel; and
an anti-fracture score disposed parallel and contiguous with the main score,
wherein a residual or thickness of material of scoring ranges from 0.0045 to 0.0057 inch;
wherein the anti-fracture score has a width of 0.0012 inch.
20 . The can end of claim 19 , further comprising a shadow bead defined on the tear panel.
21 . The can end of claim 19 , wherein the can end is formed in part by a blade with a width of between 0.0002 and 0.0008 inch.
22 . The can end of claim 19 , wherein the anti-fracture score has a residual or thickness of material that is greater than the main score residual.
23 . The can end of claim 19 , wherein an anti-fracture score residual is between 0.001 and 0.003 inch higher than a main score residual.
24 . The can end of claim 19 , wherein the main score and the anti-fracture score are disposed across a relieved portion of a bubble.
