Abstract
Tamper-evident containers are disclosed, including a container body with a neck portion and an annular collar portion below the neck portion, and a closure for application to that container body. The closure includes a one-piece closure body including a horizontal end wall and a cylindrical side wall having a depending lower skirt portion with an inwardly projecting bead having a predetermined length. The intermediate side wall portion of said closure includes an area of weakness designed to fracture when the closure is removed from the container body so as to leave the depending lower skirt portion on the container body after the upper portion of the closure has been removed, and the annular collar portion of the container body includes an upper raised portion, a lower raised portion, and a central depressed portion therebetween, the central depressed portion having a diameter less than the diameter of the upper and lower raised portions, and having a length substantially corresponding to the predetermined length of the inwardly projecting bead. In this manner, the inwardly projecting bead can be locked between the upper raised portion and the lower raised portion in order to facilitate fracture of the frangible portion of the closure as the closure is removed from the container body.
