  • Child-resistant latch for trigger sprayer
    Patent number: 5823396
    Abstract: A removable latch for use with a trigger actuated pump sprayer renders the sprayer child-resistant as the latch, of a one-piece plastic molded construction, is braced between a trigger actuator and an opposing portion of the pump body. The latch has an integrally molded spring biased clamp which engages the tongue of the trigger actuator provided for transmitting the manual pull force applied to the trigger to the pump piston. The latch has a spring-biased clamp engaging the tongue for removably securing the latch in place.

  • Plunger lock-up dispenser
    Patent number: 5615806
    Abstract: A pump dispenser has a plunger lock-up feature in which the plunger is positively retained against dislodgement by cradling projections on the piston stem against abutment shoulders of a locking sleeve which is fixed within the pump body of the dispenser. The pump body may be of an integral one-piece construction with the container closure, and the container vent opening is controlled by an upstanding sleeve on the piston cup for preserving the integrity of the piston seals.
