Abstract
Abstract This relates to a container neck finish which is particularly constructed to have an interlock with a closure of the pry-off type. The container neck finish has a peripherally projecting locking bead which includes an upper camming surface and a lower locking surface, and the associated closure has within the skirt thereof an extension of the usual gasket or sealing liner wherein, when the closure is applied to the neck finish locking bead, will deform the adjacent portion of the liner and form an interlock therewith which serves to retain the closure in place. The interlock permits the prying off of the closure and will serve again to retain the closure in place for the purpose of maintaining the original seal when the closure is reapplied.

Claim 1
Independent Claim
133 words
A container neck finish for receiving in pry-off relation a closure which may be resealed with said neck finish, said neck finish providing an end surface for sealing engagement by a closure, and axially below said end surface in remote spaced relation a radially outwardly projecting locking bead for locking engagement by a closure to retain such closure on said neck finish, said locking bead being spaced from said end surface by an axially elongated cylindrical surface, and the peripheral size of the exterior of said neck finish above said locking bead being greater than the peripheral size of the exterior of said neck finish below said locking bead with an upper surface of said locking bead being a camming surface and a lower surface of said locking bead being a locking surface.
Claim 2
Dependent Claim
133 words
