Closure with improved pull tab

Claim 2

A closure cap for a container in which the closure cap has a lower portion sealed to the container and an upper portion adapted for removal to enable access to the material within the container, a pair of peripheral grooves defining a tear strip which separates the upper portion from the lower portion, and a handle extending outwardly from the tear strip and operable when pulled to remove the tear strip, the improvement comprising, in combination: said handle having a portion contiguous with said tear strip and extending radially outwardly from said cap with one side of said handle portion facing the tear direction and being rigidly connected to said tear strip and the other side of the handle portion facing the opposite direction; one end of the tear strip terminating adjacent said other handle side to provide a frangible start location; and a gusset bridging said handle portion and tear strip on said one handle side to extend the fulcrum point of the handle into the tear strip tear direction thereby providing relatively greater leverage.

Claim 3

A closure cap as described in claim 1, said handle having a graspable outer portion extending substantially normal to said radially outwardly extending portion, and a second gusset bridging said radially outwardly extending portion and said outer normally extended handle portion to rigidify said handle.

Claim 4

A closure cap as described in claim 1, said radially outwardly extending portion having substantially the same height as the tear strip and being formed integrally with the tear strip.

Claim 5

A closure cap as described in claim 3, said angled gusset having a significantly smaller height dimension than the height of said radially outwardly extending portion.

Claim 6

A closure cap as described in claim 4, said gusset having an outer edge that defines an angle of about 20° to 50° between the tear strip and said outer edge.

Claim 7

A closure cap as described in claim 2, said first and second gussets having outer edges that are substantially parallel to each other.

Claim 8

A closure cap as described in claim 1, wherein said one end of the tear strip is tapered inwardly and terminates prior to engagement with said handle.

Claim 9

A closure cap for a container in which the closure cap has a lower portion sealed to the container and an upper portion adapted for removal to enable access to the material within the container, a pair of peripheral grooves defining a tear strip which separates the upper portion from the lower portion, and a handle extending outwardly from the tear strip and operable when pulled to remove the tear strip, the improvement comprising, in combination: said handle having a portion contiguous with said tear strip and extending radially outwardly from said cap with one side of said handle portion facing the tear direction and being rigidly connected to said tear strip and the other side of the handle portion facing the opposite direction; one end of the tear strip terminating adjacent said other handle side to provide a frangible start location; and a first gusset bridging said handle and tear strip on said one handle side to extend the fulcrum point of the handle into the tear strip tear direction thereby providing relatively greater leverage; said handle having a graspable outer portion extending substantially normal to said radially outwardly extending portion, and a second gusset bridging said radially outwardly extending portion and said normally extending outer handle portion to rigidify said handle; said radially outwardly extending portion having substantially the same height as the tear strip and being formed integrally with the tear strip; said first gusset having a significantly smaller height dimension than the height of said radially outwardly extending portion.

Claim 10

A closure cap for a container in which the closure cap has a lower portion sealed to the container and an upper portion adapted for removal to enable access to the material within the container, a pair of peripheral grooves defining a tear strip which separates the upper portion from the lower portion, and a handle extending outwardly from the tear strip and operable when pulled to remove the tear strip, the improvement comprising, in combination: said handle having a portion contiguous with said tear strip and extending radially outwardly from said cap with one side of said handle portion facing the tear direction and being rigidly connected to said tear strip and the other side of the handle portion facing the opposite direction; one end of the tear strip terminating adjacent said other handle side to provide a frangible start location; and a first gusset bridging said handle and tear strip on said one handle side to extend the fulcrum point of the handle into the tear strip tear direction thereby providing relatively greater leverage; said handle having a graspable outer portion extending substantially normal to said radially outwardly extending portion, and a second gusset bridging said radially outwardly extending portion and said normally extending outer handle portion to rigidify said handle; said radially outwardly extending portion having substantially the same height as the tear strip and being formed integrally with the tear strip; said first gusset having a significantly smaller height dimension than the height of said radially outwardly extending portion.

Claim 11

A closure cap as described in claim 8, wherein said one end of the tear strip is tapered inwardly and terminates prior to engagement with said handle.

Claim 12

A closure cap for a container in which the closure cap has a lower portion sealed to the container and an upper portion adapted for removal to enable access to the material within the container, a pair of peripheral grooves defining a tear strip which separates the upper portion from the lower portion, and a handle extending outwardly from the tear strip and operable when pulled to remove the tear strip, the improvement comprising, in combination: said handle having a portion contiguous with said tear strip and extending radially outwardly from said cap with one side of said handle portion facing the tear direction and being rigidly connected to said tear strip and the other side of the handle portion facing the opposite direction; one end of the tear strip being tapered inwardly and terminating prior to engagement with said handle to provide a frangible start location; a gusset bridging said handle and tear strip on said one handle side to extend the fulcrum point of the handle into the tear strip tear direction thereby providing relatively greater leverage; and said radially outwardly extending portion having substantially the same height as the tear strip and being formed integrally with the tear strip, said gusset having a significantly smaller height dimension than the height of said radially outwardly extending portion.

Claim 13

A closure cap for a container in which the closure cap has a lower portion sealed to the container and an upper portion adapted for removal to enable access to the material within the container, a pair of peripheral grooves defining a tear strip which separates the upper portion from the lower portion, and a handle extending outwardly from the tear strip and operable when pulled to remove the tear strip, the improvement comprising, in combination: said handle having a portion contiguous with said tear strip and extending radially outwardly from said cap with one side of said handle portion facing the tear direction and being rigidly connected to said tear strip and the other side of the handle portion facing the opposite direction; one end of the tear strip being tapered inwardly and terminating prior to engagement with said handle to provide a frangible start location; a gusset bridging said handle and tear strip on said one handle side to extend the fulcrum point of the handle into the tear strip tear direction thereby providing relatively greater leverage; and said radially outwardly extending portion having substantially the same height as the tear strip and being formed integrally with the tear strip, said gusset having a significantly smaller height dimension than the height of said radially outwardly extending portion.

Claim 14

A closure cap as described in claim 10, said handle having a graspable outer portion extending substantially normal to said radially outwardly extending portion, and a second gusset bridging said radially outwardly extending portion and said normally extending outer handle portion to rigidify said handle.

Claim 15

A closure cap as described in claim 10, said gusset having an outer edge that defines an angle of about 20° to 50° between the tear strip and said outer edge.
