Abstract
Abstract A closure is described for sealing containers such as beverage or liquor or other containers. The closure is a unitary molded closure cap which includes a flowed-in sealing gasket. A tamperproofing band may be applied with the closure cap which is locked onto a bead on the container so that it is torn free from the upper sealing portion of the cap or partly torn free and its circular form broken when an attempt is made to turn the closure cap off of the container.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
114 words
A unitary molded plastic closure cap for sealing a container having a threaded neck comprising the combination of: a cover; a depending skirt having container engaging threads on its inner surface; a radially inwardly extending bead positioned on said skirt between said cover and saidskirt threads and forming a'liner retaining groove between said cover and said threads and facilitating stripping the molded thread form portions; a flowed-in plastic sealing liner positioned on the underside of said skirt with its outer edge occupying said groove; and said liner having its greater width at its outer edge and occupying substantially the entire groove and having a progressively lesser width radially inwardly of the closure cap cover.
Claim 2
Dependent Claim
114 words
A unitary molded plastic closure cap for sealing a container having a threaded neck comprising the combination of: a cover; a depending skirt having container engaging threads on its inner surface; a radially inwardly extending bead positioned on said skirt between said cover and saidskirt threads and forming a'liner retaining groove between said cover and said threads and facilitating stripping the molded thread form portions; a flowed-in plastic sealing liner positioned on the underside of said skirt with its outer edge occupying said groove; and said liner having its greater width at its outer edge and occupying substantially the entire groove and having a progressively lesser width radially inwardly of the closure cap cover.
Claim 3
Dependent Claim
41 words
The closure cap as claimed in Claim 1 which further comprises a tamper indicating band releasably attached to the bottom of said depending skirt by spaced frangible bridges, and lug means 'on said band for engaging a bead on the container.
Claim 4
Dependent Claim
50 words
The closure cap as claimed in Claim 2 in which said lug means and said frangible bridge means are spaced from one another and proportioned for providing reduced attaching force to same tamper indicating band directly above the lug means compared to the attaching force away from the lug means.
Claim 5
Dependent Claim
31 words
The closure cap as claimed in Claim 3 in which said bridge means comprises one or more bridges and said lug means comprises one or more lugs spaced from said bridges.
Claim 6
Dependent Claim
41 words
The closure cap as claimed in Claim 3 in which said bridge means comprises bridges approximately diametrically spaced from one another and said lug means comprises lugs each spaced about half way between said bridges and approximately diametrically from one another.
Claim 7
Dependent Claim
33 words
The closure cap as claimed in Claim 5 in which one of said bridge means comprise a hinge providing a stronger connection between said skirt and said band than said other bridge means.

Dependent Claim
17 words
The closure cap as claimed in Claim 1 in which said bead has a generally triangular cross-section.
Claim 10
Dependent Claim
25 words
The closure cap as claimed in Claim 8 in which the apex of the triangular cross section is the radially innermost portion of said bead.
Claim 11
Dependent Claim
15 words
The closure cap as claimed in Claim 8- in which said apex comprises a radius.
Claim 12
Dependent Claim
31 words
The closure cap as claimed in Claim 1 in which the uppermost surface of said bead facing the cap cover has a 25 0 to 60° angle with the cap cover.
Claim 13
Dependent Claim
104 words
A generally cylindrical molded plastic closure cap for sealing a container comprising the combination of: a disc-like cover; a depending generally cylindrical skirt; a radially inwardly extending circular bead positioned on said skirt between said cover and said skirt forming a liner retaining groove between said cover and said threads; a disc-like flowed-in plastic sealing liner positioned on the underside of said skirt and occupying said groove; said liner having its greatest width at its outer edge and occupying substantially the entire groove and having a progressively lesser width radially inwardly of the closure cap cover, being approximately one half of said greatest width.
Claim 14
Dependent Claim
104 words
A generally cylindrical molded plastic closure cap for sealing a container comprising the combination of: a disc-like cover; a depending generally cylindrical skirt; a radially inwardly extending circular bead positioned on said skirt between said cover and said skirt forming a liner retaining groove between said cover and said threads; a disc-like flowed-in plastic sealing liner positioned on the underside of said skirt and occupying said groove; said liner having its greatest width at its outer edge and occupying substantially the entire groove and having a progressively lesser width radially inwardly of the closure cap cover, being approximately one half of said greatest width.
Claim 15
Dependent Claim
40 words
The closure cap as claimed in Claim 12 which further comprises a tamper indicating band releasably attached to the bottom.of said depending skirt by spaced frangible bridges, and lug means on said band for engaging a bead on the container.
