Abstract: A device for use by a smoker to introduce treatment fluids into a cigar, cigarette, charge of pipe tobacco and similar consumer units of smoking tobacco.

Abstract: A dispensing system is disclosed for use with a liquid dispensing package that includes a container and a system for forcing liquid from the container. The dispensing system directs liquid forced from the container to a defined area such as the eye and comprises a selectively operable nozzle that is mounted with the container to be movable relative thereto between liquid-dispensing and closed positions. The nozzle has an outlet orifice from which liquid is dispensed. An overcap is mounted in fixed relation with the container and defines an opening with which the nozzle orifice is registered when in the liquid-dispensing position. A shield, which directs liquid from the nozzle to the defined area, has an inlet aperture, a coupling arrangement for mounting the shield on the overcap with the inlet aperture registered with the overcap opening, and an outlet aperture remote from the inlet aperture.

Abstract: A finger-operable pump, adapted to be mounted on a hand-held container of liquid consumer product to provide an unpressurized dispenser package, includes a housing, that defines a pumping chamber, and a plunger telescopically received in the chamber for conventional pumping movement. A stem formed with the plunger projects outwardly of the housing. The pump further incorporates an inprovement in the form of an automatically operable seal arrangement for preventing leakage of liquid which comprises a conical valve seat formed about the mouth of a discharge passage through the plunger and stem and a valve element, having dome-shaped and conical portions, located in the pumping chamber to sealingly engage the valve seat. An actuator button is mounted on the outer end of the plunger stem and is linked, through an elongated connecting rod, to the valve element to move it out of engagement with the valve seat and then to reciprocate the plunger into the pumping chamber away from a home position.

Abstract: A finger operated accumulator release pump, adapted to be mounted on a container to dispense liquid therefrom only after the liquid has been pressurized by a predetermined amount, comprises a housing which defines a pump chamber and an inlet to the pump chamber. A conventional check valve prevents return flow of liquid through this inlet. A plunger is telescopically received for reciprocal pumping action in the pump chamber, makes a sliding piston fit with it, and is provided with an outlet passage and a valve seat at the inlet end of the outlet passage. The pressure accumulating release feature of the pump is provided by cooperation of an outlet passage by-pass arrangement and a pressure actuated accumulator valve. The by-pass arrangement comprises a number of by-pass grooves which are disposed in a generally axial direction on the inner surface of the outlet passage at a location intermediate its ends.

Abstract: An easily assembled, low cost, disposable pump is disclosed for use with household liquid product containers. The pump is designed to prevent leakage of the product regardless of container attitude and comprises hollow outer and inner cylinders, each having an end wall, the cylinders being nested in telescoped manner with their end walls in spaced adjacency to form an intake valve chamber and a superimposed product receiving and discharging pump chamber. Liquid inlet duct means is formed in the respective end walls of each cylinder for admission of fluid, and a plunger assembly including a hollow stem and a piston is slidably received in the inner cylinder for reciprocable pumping action therein. The hollow stem provides communication between the pumping face of the piston and atmosphere, via a check valve disposed in the stem. A second check valve is disposed in the valving chamber formed by the telescoped cylinders.

Abstract: The disclosed device is a finger operated plunger pump which is mountable in the mouth of a hand-held container for liquid products to provide an unpressurized dispenser package for consumer use. The pump includes the usual pump cylinder, plunger, discharge nozzle, check valves and cap for mounting the pump on the container, and is characterized by provision of a lockable seal for the discharge passage, the seal being selectively operable by the user to disable the pump and simultaneously seal it against leakage. The disablement of the pump is effected by limited rotation of one seal member relative to its complementary member to shift them between seated and unseated positions, such rotation being effected by turning the pump plunger relative to its cylinder through a connection including a telescoping stem which accommodates normal plunger reciprocation.
