Abstract

The invention provides snap-on, twist-off container closure assemblies including one or more of the following features: (1) a sealing plug on the closure for insertion into the container neck, said plug having an outer annular sealing recess or sealing rib for engagement with an annular sealing rib or sealing recess on the inside of the container neck to form a seal; (2) complementary first and second locking elements on the container neck and the closure which engage to resist twisting-off of the closure from the neck until a predetermined minimum opening torque is applied to the closure, the assembly further comprising an alignment means to align the first and second locking elements when the closure is snap-fitted onto the container neck; and (3) ramped first and second thread segments on the container neck and the closure to reduce the axial force required to snap the closure onto the container neck relative to the axial force required to snap the closure off the container neck; and (4) a sealing web on the container neck and a compressible sealing wad in the base of the closure to form a seal with the container neck after removal of the sealing web.
