ABSTRACT:
A snap-lock device, for securing a dispensing mechanism to the mouth of a container which has an annular bead about the mouth periphery, comprises a bead embracing ring having an axially extending annular recess open at one end of its axial extent to receive the bead. An annular rib, formed with the ring adjacent the open margin of the recess, underlies at least a portion of the bead to prevent axial bead-ring disengagement. A retainer element, engageable on the ring when installed on the bead, exerts a radial force against the ring and holds the rib in underlying relation to the bead. The dispensing mechanism is mounted with one of the ring and element. A rabbeted interlocking arrangement between the ring and element prevents their relative disengagement so that the dispensing mechanism cannot be removed from the container. Therefore, the device can be used with pressurized barrier-type and aerosol containers.
