Abstract
This invention relates to a thermoplastic tamper-indicating closure. The closure features a top wall and an annular downwardly depending sidewall. Connected to the lower end of the annular sidewall by way of an annular frangible area is an annular tamper-indicating band. The tamper-indicating band features an annular upper portion which depends downwardly from the frangible area. The band additionally has an annular lower portion hingedly connected to the annular upper portion and which comprises a plurality of spaced apart tabs with each tab connected to its neighboring tab by way of a flexible web. Each of the tabs preferably has a scalloped recess at their lower extent to provide some circumferential flexibility when the annular lower portion of the band is hinged inwardly from its molded position to its utilitarian position.
