Patent ID: 7451898

Claim:
A tamper evident closure, comprising: a body portion comprising a base and an internally threaded downwardly depending sidewall portion; and a tamper evident band frangibly connected to said sidewall portion, said tamper evident band comprising: a main band portion, and a J-hook retention member that includes a plurality of separate pleated retaining elements with a pleated shape on their inside and their outside, wherein at least one pleat is folded perpendicular to the lower rim of said sidewall portion, and wherein at least one of the pleated retaining elements has on its inside and on its outside at least one inwardly directed fold and at least one outwardly directed fold, and wherein each of said retaining elements has an upper portion that is constructed and arranged to engage retention structure of a container in order to prevent upward movement of said tamper evident band with respect to the container, and wherein at least one of the pleated retaining elements is further constructed and arranged to engage the container so as to resist rotation with respect to the container, whereby separation of said tamper evident band from said body portion is better assured when the closure is unscrewed from the container and wherein said at least one pleated retaining element comprises a leading edge that is shaped so as to permit said retaining element to pass over said rotational locking structure when said closure is first screwed onto the container and wherein said at least one pleated retaining element further comprises a trailing edge that is shaped so as to firmly engage said rotational locking structure when said closure is being unscrewed from the container.
