Abstract: A closure for a container neck having a crown, a reduced diameter portion, a downward facing shoulder, and an enlarged diameter portion. The crown defines an opening and an outwardly extending locking bead. The closure includes a cap, a skirt, a well, a frangible membrane, a pull ring, and a retainer. The skirt depends from the top and is adapted to fit around the crown and the enlarged diameter portion of the container neck. The well includes an upper side wall depending from the top, an inwardly directed shoulder located adjacent a bottom of the upper wall, and a lower side wall depending from the inwardly directed shoulder. The lower side wall has an interior surface and the lower side wall terminating at an open bottom. The frangible membrane in the well closes off the well and includes a line of weakness frangibly connecting the frangible membrane to the lower side wall adjacent the inwardly directed shoulder. The pull ring is attached to an upper surface of the frangible membrane.

Abstract: Lotion pump has a stepped piston telescoping inside a stepped body to define a pumping chamber. The piston has a downward annular wall having inlet and discharge apertures, one above the other, to the pumping chamber. A stem integral with the actuator has a sealing head inside the annular wall which shuttles up and down between positions at which it covers one aperture or the other. Shuttling is implemented by lost-motion between the actuator spout/stem and piston. A spring urges the stem up at all times. The actuator can be turned to lock the head over the discharge aperture by nullifying the lost-motion. Further turning can lock the stem in lockdown position. One-directional turnback can liberate the head and unlock the lockdown. Detents control sequence of unlocking.
