Abstract
Tamper-evident containers are disclosed, including a container having a neck portion and an annular collar portion located below the neck portion, and a closure for application to the container including a one-piece closure body having a horizontal end wall and a cylindrical side wall including an upper portion, a depending lower skirt portion, and an intermediate side wall portion therebetween. The depending lower skirt portion includes an inwardly projecting bead having an internal diameter which is no greater than the outer diameter of the container at a predetermined location directly below the annular collar portion, so as to provide an interference fit therebetween at that predetermined location when the closure is completely applied to the container. The intermediate side wall portion includes an area of weakness which is designed to fracture when the closure is removed from the container, so as to leave the depending lower skirt portion on the container after the upper portion has been removed, and the container includes an inwardly directed non-locking tapered surface at that predetermined location, whereby after fracture of the closure at the area of weakness the depending lower skirt portion is caused to move downwardly along the non-locking tapered surface and away from the annular collar portion to provide visual evidence of fracture.
