  • Dual liquid tight closures
    Patent number: 4351443
    Abstract: A container and closure construction featuring double means of liquid tight-sealing with a threaded closure so arranged as to double seal combined or sequentially against two separate areas of the rim of a container neck to provide sealing properties even when closure is partially unscrewed from the top of the rim of the container. A preferred embodiment has its application of the above arrangement together with child proof safety closures having unique safety locking arrangements in the form of coincidentally registered abutments and projections formed in and/or on said container and closure which do not substantially interfere with applying the closure to the container but which can be disengaged only through purposeful mind-controlled dextrous manipulation.
