The closure (10,30) comprising a top portion (11) and a skirt portion (12) depending from the top portion (11). A tamper evident band (13,33) is joined to the skirt portion (12) by one or more frangible connectors (14,34). The band (13,33) comprises a first portion (15,35) extending generally away from the skirt portion (12) and a second portion (16,36) hingedly connected to the first portion (15,35) and movable between a first moldable orientation and at least a second operable orientation. For closure (10), the second portion (16) comprises a plurality of curved undercuts (18) extending at least partially into a cavity of the closure (10) when it is in its operable orientation. For closure (30), the inner surface (35a) of the first portion (35) can have a plurality of inwardly extending protuberances (40) positioned thereon. ## Claims ### Claim 1 A closure attachable to a container having an opening, the closure comprising: a top portion; a skirt portion depending from the top portion, said top portion and skirt portion defining a cavity; and a tamper evident band joined to the skirt portion by one or more frangible connectors; wherein the band comprises: a first portion extending generally away from the skirt portion; and a second portion hingedly connected to the first portion and movable between a first moldable orientation and at least a second operable orientation; the second portion comprising a plurality of curved undercuts extending at least partially into the cavity when in said operable orientation. ### Claim 2 (depends on 1) The closure of claim 1 wherein the second portion of the band is hingedly connected to the first portion through a hinge connection. ### Claim 3 (depends on 1) The closure of claim 1 wherein the second portion further comprises relatively thinned sections integrally formed between two, between some, or between each of the curved undercuts. ### Claim 4 (depends on 1) The closure of claim 1 wherein one, some or all of the curved undercuts comprise an inner wall and an outer wall and extend from the hinge connection to the inner edge. ### Claim 5 (depends on 4) The closure of claim 4 wherein the inner wall is convex and the outer wall is concave. ### Claim 6 A closure attachable to a container having an opening, the closure comprising: a top portion; a skirt portion depending from the top portion, said top portion and skirt portion defining a cavity; and a tamper evident band joined to the skirt portion by one or more frangible connectors; wherein the band comprises: a first portion extending generally away from the skirt portion and having an inner surface; and a second portion hingedly connected to the first portion and movable between a first moldable orientation and at least a second operable orientation; wherein the inner surface of the first portion has one or a plurality of inwardly extending protuberances. ### Claim 7 (depends on 6) The closure of claim 6 wherein the protuberances are provided on the inner surface at or adjacent the free end of the first portion. ### Claim 8 (depends on 6) The closure of claim 6 wherein the protuberances are hemispherical bumps. ### Claim 9 (depends on 6) The closure of claim 6 comprising a plurality of equally spaced protuberances. ### Claim 10 (depends on 6) The closure of claim 6 wherein the protuberances have an inwardly extending dimension that serves to ensure the second portion cannot collapse completely back against the inner surface of the first portion when the closure is attached to a container finish. ### Claim 11 (depends on 6) The closure of claim 6 wherein the second portion has a dimension extending from a hinge connection with the first portion to the inner edge that is greater than the longitudinal dimension of the protuberances. ### Claim 12 (depends on 11) The closure of claim 11 wherein the dimension of the second portion is approximately equal to twice the longitudinal dimension of the protuberances. ### Claim 13 (depends on 1, 6) The closure of claim 1 or claim 6 wherein the one or more frangible connectors comprise frangible bridges. ### Claim 14 (depends on 1) A container/closure combination with the container having an opening sealed by a closure as defined by claim 1. ### Claim 15 (depends on 1) A mold for forming a closure as defined in claim 1, the mold comprising a cavity shaped to form the tamper evident band with the second portion thereof in a molded orientation. ### Claim 16 (depends on 1) A method of forming a closure according to claim 1 comprising: molding the closure with an integral tamper evident band, said second portion of the band being in a moldable orientation in which said curved undercuts extend outwardly; and re-orienting the second portion of the band relative to the first portion to a position wherein the curved undercuts extend into the cavity of the closure. ### Claim 17 (depends on 1) A method of attaching a closure according to claim 1 to a container, the method comprising turning the closure onto the container until the closure seals the container and the curved undercuts are positioned under a retaining flange on the container. ### Claim 18 (depends on 6) A method of forming a closure according to claim 6 comprising: molding the closure with an integral tamper evident band, said second portion of the band being in a moldable orientation; and re-orienting the second portion of the band relative to the first portion to a position where it is adjacent the first portion. ### Claim 19 (depends on 6) A method of attaching a closure according to claim 6 to a container, the method comprising turning the closure onto the container until the closure seals the container and the second portion is positioned under a retaining flange on the container.
