COMPOSITE CLOSURE
First Claim
1. A closure and container package comprising:
- the container having a neck with container threads formed thereon;
the closure including;
a circular disk including an arcuate curl formed at a periphery thereof, the disk for disposing on the container neck to form a seal therebetween, and a band including;
an annular skirt including closure threads formed on an interior surface thereof; and
plural fins extending inwardly from the skirt, the fins having a first, as-molded state prior to application of the closure onto the container and a second, fully applied state in which the fins deform upon receiving the curl when the closure is applied onto the container;
whereby in the first state the disk is not tightly secured to the band and in the second state the fins engage the curl to secure the band to the disk.

Abstract
A composite closure includes a band and an insert disk. A contact surface urges downwardly against the disk even while the band moves longitudinally relative to the disk or container. The closure has a fully tightened position in which the band'"'"'s ring contacts the disk'"'"'s annular channel, a loose position in which the ring is spaced apart from the annular channel, and an intermediate tightened position in which the ring is spaced apart from the disk and the contact surface urges against the curl. Another composite closure includes plural fins or gussets. The fins or gussets engage the peripheral curl of the insert disk to secure the band to the disk, which provides a resistance to initial unscrewing of the band. The disengagement torque required to disengage the curl from the fins may enable the closure to function as a one-piece closure.

14. A composite closure comprising:
-
a circular disk including a curl formed at a periphery thereof, the disk is capable of being positioned on a container neck to form a seal therebetween, and a band including;
an annular skirt including closure threads formed on an interior surface thereof, and plural fins extending inwardly from the skirt, the fins having a first, as-molded state prior to application of the closure onto a container and a second, fully applied state in which the fins deform upon receiving the curl when the closure is applied onto the container;
whereby in the first state the disk is not tightly secured to the band and in the second state the fins engage the curl to removably secure the band to the disk. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A composite closure comprising:
-
a circular disk including a curl formed at a periphery thereof, the disk capable of being positioned on a container neck to form a seal therebetween, and a band including;
an annular skirt including closure threads formed on an interior surface thereof, and contact means located on an interior portion of the skirt, the contact means having a first, as-molded state prior to application of the closure onto a container and a second, fully applied state in which the contact means deform when receiving the curl upon application of the closure onto the container;
whereby in the first state the disk is not tightly secured to the band and in the second state the contact means engage the curl to secure the band to the disk.

28. A composite closure comprising:
-
a circular disk including a curl formed at a periphery thereof, the disk is capable of being positioned on a container neck to form a seal therebetween, and a band including;
an annular skirt including closure threads formed on an interior surface thereof, and at least one upper contact member extending inwardly from the skirt, the upper contact member having a contact surface that consists essentially of a downwardly-and-inwardly-facing surface that has a first, as-molded state prior to application of the closure onto a container and a second, fully applied state in which the contact surface deforms when receiving the curl upon application of the closure onto the container;
whereby in the second state the downwardly-and-inwardly-facing surface engages the curl to secure the band to the disk. - View Dependent Claims (29, 30, 31)
