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.
