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 area is an annular tamper-indicating band. The annular area has a frangible and a non-frangible portion. The tamper-indicating band has a vertical frangible area which extends across its width and which is preferably generally opposite the non-frangible area. The tamper-indicating band also features an annular upper portion which depends downwardly from the annular area. The band additionally has an annular lower portion which comprises a plurality of spaced-apart tabs, each tab connected to its neighboring tab by way of a flexible web. Each of the tabs has an outwardly extending projection at its lowermost extent. These projections each provide a surface which will be placed in a position of interference with a container annular flange when the tabs are bent inwardly and upwardly and the closure is fitted to the container. The annular upper portion is connected to the annular lower portion by way of an annular hinge.
