Abstract
This invention relates to a thermoplastic closure having a top wall and an annular sidewall downwardly depending therefrom. By way of an annular frangible area, there is an annular tamper-indicating band connected to the lowermost extent of the closure annular sidewall. The annular tamper-indicating band has an annular upper portion which depends downwardly from the annular frangible 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.
