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 retaining flaps and a plurality of connector elements extending only between said retaining flaps, each of said connector elements being unitary at a first end with a first retaining flap and at a second end with a second retaining flap, whereby said connector elements and said retaining flaps extend in a continuous closed hoop-like structure, and wherein said connector elements have a first maximum height and said retaining flaps have a second maximum height, and wherein said first height is within a range of about 50 percent to about 95 percent of said second height; and wherein each of said retaining flaps 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 retaining flaps 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 assured when the closure is unscrewed from the container, and wherein each of said retaining flaps is shaped as to include a first convexly radius ramp portion, a second convexly radiused ramp portion and a flat forward portion, which is provided between the first and the second convexly radiused ramp portion.
