A lockable fluid dispenser cap is used with a dispensing pump for dispensing a fluid product from a container. The dispenser cap includes a container closure, locking fingers mounted to the closure, a lock actuating member rotatably mounted to the closure, and a pump actuating member coupled to the lock actuating member. The closure mounts the pump in the container. The locking fingers are mounted to the closure and normally spaced in unlocking relation from the pump piston but are yieldably flexible for bending toward the piston. The lock actuating member has cam elements which upon rotation of the lock actuating member forcibly bend the fingers toward the piston and into a locking relation therewith. Reciprocal movement of the pump actuating member relative to the lock actuating member is used to actuate the piston. Also, rotational movement of the pump actuating member is used to cause rotation of the lock actuating member therewith for bending the fingers from their unlocking to locking relations. The pump actuating member includes a fluid collecting dish which receives fluid product from the pump when the locking fingers are in unlocking relation with the piston permitting reciprocal movement of the pump actuating member and the piston connected thereto toward and away from the cylinder for discharging fluid product from the piston to the collecting dish.

A lockable fluid dispenser cap for use with a fluid product dispensing pump having a cylinder and a piston mounted by the cylinder for reciprocal movement to draw a fluid product through the cylinder and piston and dispense the fluid product outwardly through a fluid discharge outlet in an outer end of the piston, said lockable dispenser cap comprising: (a) a container closure adapted for attachment to an upper end of a container holding the fluid product and for mounting the pump at the cylinder thereof so as to support the pump in the container; (b) at least one locking finger mounted to said closure and adapted to extend along an outer portion of the piston when the pump is mounted to said closure, said locking finger normally positioned in an outward radially spaced relation from the piston but being yieldably flexible for bending toward the piston; (c) a lock actuating member rotatably mounted to said closure and disposed adjacent said locking finger, said lock actuating member having at least one cam element which upon rotation of said lock actuating member in one direction moves toward said locking finger to forcibly bend said finger toward the piston and into a locking relation therewith whereas upon rotation of said lock actuating member in an opposite direction said cam element moves away from said locking finger permitting said finger to return to its normal position spaced from the piston and into an unlocking relation therewith; (d) a pump actuating member connected to the piston and coupled to said lock actuating member for rotational movement to cause rotation of said lock actuating member therewith for positioning said locking finger in its respective locking and unlocking relations with the piston, said pump actuating member also coupled to said lock actuating member so as to be capable of reciprocal movement relative thereto for causing dispensing of fluid product from the piston when said locking finger is in its unlocking relation with the piston but incapable of reciprocal movement when said locking finger is in its locking relation with the piston; and (e) said pump actuating member including an outer fluid collecting dish having at least one inlet hole defined therein in communication with the fluid discharge opening in the outer end of the piston for dispensing of fluid product from the piston onto said outer collecting dish.
