Abstract
Abstract The closure cap is provided with an extension of the skirt thereof with the skirt extension having formed therein lines of weakening and having at a lower end thereof an anchoring band which, when the closure cap is applied to a container neck finish, will permanently anchor the closure cap to the container, thus preventing littering by the separate dispensing of the closure cap. The skirt extension is provided with a line of weakening arrangement which, when a cap portion is removed from the container, will rupture and which will define a tethering strap which permanently retains the cap portion to the anchoring band while permitting any required rotation and axial movement of the cap portion to facilitate cap portion removal and product dispensing.

Total Claims: 5
Claim 1
Independent Claim
173 words
A tethered closure cap comprising an upper cap portion including an end panel and a skirt, and a lower tether portion in the form of an extension of said skirt, said skirt extension being joined to said skirt along a first peripheral weakening line having a first starting end spaced from a first terminal end, said skirt extension including a lower anchoring band, a second peripheral weakening line separating said anchoring band from an upper part of said skirt extension, said second peripheral weakening line having a second starting end spaced from a second terminal end, an intermediate weakening line joining said first terminal end to said second starting end, first anchoring means carried by said skirt for releasably securing said cap to a container, and second anchoring means for permanently securing said anchoring means to the same container, all of said weakening lines being in the form of open spaces interrupted by bridges, and said intermediate weakening line being defined by angular extensions of spaces of said first and second weakening lines.
Claim 2
Dependent Claim
173 words
A tethered closure cap comprising an upper cap portion including an end panel and a skirt, and a lower tether portion in the form of an extension of said skirt, said skirt extension being joined to said skirt along a first peripheral weakening line having a first starting end spaced from a first terminal end, said skirt extension including a lower anchoring band, a second peripheral weakening line separating said anchoring band from an upper part of said skirt extension, said second peripheral weakening line having a second starting end spaced from a second terminal end, an intermediate weakening line joining said first terminal end to said second starting end, first anchoring means carried by said skirt for releasably securing said cap to a container, and second anchoring means for permanently securing said anchoring means to the same container, all of said weakening lines being in the form of open spaces interrupted by bridges, and said intermediate weakening line being defined by angular extensions of spaces of said first and second weakening lines.
Claim 3
Dependent Claim
26 words
A tethered closure according to claim 1 wherein said bridges of said first weakening line are peripherally offset from said bridges of said second weakening line.
Claim 4
Dependent Claim
172 words
A tethered closure cap comprising an upper cap portion including an end panel and a skirt, and a lower tether portion in the form of an extension of said skirt, said skirt extension being joined to said skirt along a first peripheral weakening line having a first starting end spaced from a first teminal end, said skirt extension including a lower anchoring band, a second peripheral weakening line separating said anchoring band from an upper part of said skirt extension, said second peripheral weakening line having a second starting end spaced from a second terminal end, an intermediate weakening line joining said first terminal end to said second starting end, first anchoring means carried by said skirt for releasably securing said cap to a container, and second anchoring means for permanently securing said anchoring means to the same container, all of said weakening lines are in the form of open spaces interrupted by bridges, said bridges of said first weakening line being peripherally offset from said bridges of said second weakening line.
Claim 5
Dependent Claim
