Abstract
A tamper evident, unitary, plastic overcap adapted to be placed over a container neck flange, which neck flange has, adjacent its outboard end, a radially outwardly protruding annular ridge. The overcap comprises a relatively thin, flat, round, end wall having extending axially inboard therefrom an a cylindrical skirt with a plurality of circumferentally spaced, integral projections extending radially inward from an inboard portion of said skirt and adapted to underlie a container neck flange ridge, so that said overcap cannot be removed from a container neck flange without at least partial destruction of said overcap.
