Abstract: The present invention relates to a dispenser nozzle for high pressure injection, of which injection pressure and efficiency are largely improved and the product lifespan is increased, and in which a tappet 100 has a leading end portion 101 formed in a conical shape, and a nozzle 110 includes a funnel-shaped accommodation part 111 formed for maintaining a predetermined gap G from an outer circumferential surface of the leading end portion 101 of the tappet 100, a funnel groove 112 formed in the center of a bottom surface 111a of the funnel-shaped accommodation part 111 such that the leading end portion 101 of the tappet 100 is inserted into the funnel groove 112 by a predetermined length, and an injection hole 113 penetratingly formed in the center of the funnel groove 112.

Abstract: The nozzle of the present invention has an internal chamber, condiment input and discharge ports in fluid communication with the internal chamber, and an extension downstream of the condiment discharge port. Preferably, the internal chamber has a flow disrupter taking the form of a funnel-shaped end portion adjacent to the condiment discharge port. The internal chamber is preferably elongated and has a larger cross section than the spout to which the nozzle is connected to reduce condiment pressure and flow speed entering the nozzle. Condiment pressure can also be reduced in the internal chamber by other types of flow disrupters: protrusions extending from the internal chamber walls into the condiment flow and/or by an insert received within the internal chamber. At the funnel-shaped end portion, condiment flow adjacent to the internal chamber side walls is preferably diverted toward the discharge port to generate crossflow and turbulence, further reducing condiment pressure and force.

Abstract: The present invention pertains to two inserts to be used in conjunction with the nozzles of known liquid flow through applicators. The inserts have a proximate flange detailed to fit into a wider portion of the applicator and a bristle or dabber portion at its distal end detailed to extend beyond the applicator. The bristle or dabber portions are connected by an elongated rod portion. In one embodiment the rod portion is crisscrossed with a clockwise thread and a counterclockwise thread whereby two disparate liquids may be mixed together through the flow transitory passage of the liquids in the nozzle. In the second embodiment the rod portion is essentially smooth. However, the external diameter of the rod is substantially less than the internal diameter of the passage of the applicator whereby an annular space is formed.

Abstract: A cap, spinner, and discharge nozzle assembly for use with a liquid dispensing apparatus such as a trigger sprayer. The spinner assembly can be externally fitted to the discharge nozzle, and includes an annular chamber surrounding a central post having a swirl chamber in its top. The central post includes longitudinal grooves, communicating with tangential grooves in an annular wall defining the swirl chamber. Apertures are provided in the base of the annular chamber such that pressurized liquid flows through the apertures and into the annular chamber, with a resulting reduction of velocity, and then along the longitudinal grooves and through the tangential grooves into the swirl chamber. A cap is provided which variably engages the discharge nozzle and which has at least a central projection on the inner side of its front face, and preferably an annular groove formed by an outer projection surrounding the central projection.

Abstract: A foam generating unit is adjustably mounted for longitudinal movement on a liquid sprayer having an orifice which provides a diverging liquid stream directed into the inlet of the foam generating unit. The foam generating unit includes a foam-generating section most advantageously having a pressure-reducing inlet passageway section including a preferably sharply outwardly tapering portion leading to a throat portion. Air inlet ports are provided communicating with the pressure-reducing passageway, through which ports air is drawn by the reduced pressure caused by the pressure-reducing passageway. The desired foaming action is achieved by adjusting the points of the pressure-reducing passageway section struck by the stream by moving the foam generating unit relative to the orifice.

Abstract: An improved adjustable-spray mechanism which includes a button body to be fixedly connected to the exit stem of an aerosol or other fluid container, the button body being characterized by a bore having an end wall. An orifice extends through the end wall from the bore and constitutes a spray outlet to the environment. An adjustable valve is disposed in the bore so as to selectively advance toward or retract from the end wall. Upon introduction of fluid to the bore, a variable fluid spray pattern can be obtained upon adjustment of the valve toward or away from the orifice in the wall.

Abstract: A foam generating nozzle is made either as an attachment to an existing liquid spray nozzle unit or as a pre-manufactured assembly and includes a foam-generating section having a pressure-reducing passageway including a preferably sharply outwardly tapering portion leading to a venturi-forming throat portion, and adapted to receive the liquid stream issuing from an inlet orifice. Air inlet ports are provided communicating with the pressure-reducing passageway, through which ports air is drawn by the reduced pressure caused by the pressure-reducing passageway. Optimum foaming action is achieved by adjusting the point of the pressure-reducing passageway struck by the stream which is most advantageously achieved by adjusting the angle of the stream issuing from the orifice so the widest portion thereof strikes the end section of the tapering portion of the passageway.
