Abstract
A discharge unit (1) contains two separate delivery units (15) to be actuated in common through which the medium flows along a module (35) separate from two base bodies (4,5) to two atomizer nozzles (48) so that due to their spray cones overlapping each other the two separately emerging media are intermingled in utmost fine dispersion and, e.g. with the formation of a gelling blended medium, react with each other. As a result of this two media reacting with each other chemically or physically can be intermingled not before being outside of the discharge nozzles (48) and thereby simultaneously applied to the region of application, e.g. a mucuous membrane.
Claims25
A dispenser for discharging media comprising:
- a housing (4,5) including a housing body (4);
- at least one medium delivery means (23) connected with said housing (4,5);
- said medium delivery means (23) including a moveable discharge actuator (30);
- a nozzle body (6) projecting from said housing (4, 5), said nozzle body (6) being traversed by first and second nozzle ducts (49) including first and second discharge orifices (7) that allow media dispensed through said first and second discharge orifices (7) to separately release from said dispenser (1) at said first and second discharge orifices (7), each of said first and second nozzle ducts (49) respectively including an upstream end and a downstream end providing a respective one of said discharge orifices (7);
- a nozzle insert (35) extending within said nozzle body (6) and together with said nozzle body (6) providing a longitudinally extending passageway (40) communicating between said delivery means (23) and said first nozzle duct (49);
- and
- wherein said nozzle insert (35) also includes a carrier (45) which encloses at least part of an outlet duct (37) communicating between said medium delivery means (23) and said longitudinally extending passageway (40), said nozzle insert (35) further including an end section (51) directly closely opposing and traversing said upstream end of said first nozzle duct (49), said first nozzle duct (49) being linear and circumferentially bounded in one part.
A dispenser (1) for discharging media comprising:
- a housing body (4);
- a medium delivery unit (23) including a pump;
- a nozzle including a nozzle duct (49) with an upstream end and a downstream end including a final discharge orifice (7) for releasing at least one of the media from said dispenser (1) to an environment external to said dispenser (1), and
- a nozzle insert (35) inserted in said housing body (4) and including a core rod (41) extending substantially up to said upstream end of said nozzle duct (49), said core rod (41) defining an outer circumference, said nozzle insert (35) including a support member (45) directly connecting to an upstream end of said core rod (41), located entirely inside said housing body (4) and fixed to said housing body (4) laterally outside and spaced from said outer circumference of said core rod (41) with a support connector (46).
