Definitions

  • This invention relates to a structurally and functionally improved liquid atomizer, and especially an apparatus utilized for the dispensing of perfumes, colognes, toilet waters and the like.
  • FIG. 1 is a perspective view of anatomizer mounted upon a liquid containing receptacle
  • FIG. 2 is a sectional side view in enlarged scale of one preferred form of atomizer constructed in accordance with the teachings of this invention and showing that assembly in projected position;
  • FIG. 4 is a view similar to FIG. 2 but showing the atomizer head in retracted or depressed position
  • FIG. 5 is also a view'similar to FIG. 2 but illustrating an alternative form of structure
  • FIG. 6 is a view corresponding to FIGS. 2 and 5 but showing a still further alternative design
  • FIG. 7 illustrates in section a further preferred form of valve and piston structure
  • FIG. 8 illustrates in section another form of valve and piston structure
  • the atomizer will normally be associated with a receptacle so as to be capable of attachment thereto rather portion 14 furnishing an interrupted screw thread for c0- operation'with the thread of the receptacle neck. Also,
  • ashell 16 conveniently formed of metal and prothe shell is a stem 18 conveniently provided with a spirally extending fin 19, and spaced from the inner surface defining the orifice 17, so that air may flow between the convolutions of the fin and intermingle with liquid passing through a bore (shown in phantom in FIG. 2) of stem 18 in the mixing chamber 20 intervening the outer surface of the stemvand the opposedinner fiace of shell 16. If no bore is provided through the stern, then both air and liquid will flow between the fin convolutions. Both the shell and stem project into a vertically extending bore formed in head 12, for a purpose hereinafter brought out.
  • the upper portion of the piston assembly 13 conveniently includes a metallic tube 13a. This tube is'flared in an outward direction adjacent its lower end as indicated at 13'. A bushing 21 is interposed between the tube and an outer tube 22 which latter provides a cylinder.
  • the assembly moreover includes member 24 having a flexible skirt portion 23, having wiping engagement with the cylinder wall; the upper end of this skirt being continued in the form of a boredextension.
  • This part of the piston assembly is preferably formed of a material having inherent resiliency.
  • Cylinder 22 may be reduced adjacent its lower end as indicated at 25 and mount a flexible tube portion 27 which will conveniently have a length such that it will extend adjacent the lower end of a receptacle with which the,
  • a spring 31 is provided within cylinder 22 and confined in the space between shoulder 23' formed in skirt 23 and shoulder 22' in cylinder 22.
  • a second valve structure is provided adjacent the upper zone of the atomizer. That structure conveniently includes a flared portion 32 defining the upper end of the bore extending through member 24. This furnishes a seat for valve member or body 33. The latter is normally maintained, on its seat by virtue of the fact that the lower end of a spring 34 bears against it. The upper end of the spring conveniently thrusts against the inner end of shell 16 and/or stem 18.
  • a rod 35 is provided within bore 24' of member 24 and freely movable longitudinally therein when the head 12 is in the non-depressed or raised position shown in FIG. 2.
  • the lower end of rod 35 extends downwardly within cylinder 22.
  • the diameter of this rod is such that it extends with ample clearance within the bore 24'.
  • venting opening 36 is formed intermediate the ends of cylinder 22.
  • spring 31 is limited by the lower edge zone 13' of tube 13 engaging the lower edge of bushing 21.
  • FIG. 4 the device of FIG. 2 is shown with head 12 in depressed position.
  • a second depressing of head 12 will compress the air within the cylinder 22. This will displace liquid within cylinder 22 upwardly into the bore of extension 24. In that position the lower end of rod 35 will engage ball 30 and the upper end of rod 35 will engage ball 33 of the upper valve structure displacing it from its seat 32 and against the action of spring 34. Accordingly, fluid within the bore of extension 24 will not have to overcome the seating pressure of the valve body in order to flow towards the nozzle. The liquid together with the air passing through the bore of the piston assembly will move into the nozzle. An atomized mixture will be discharged through orifice 17 from chamber 20. If desired and as indicated in FIG. 1 the nozzle may also carry a pin 37 extending outwardy therefrom and capable of being engaged by a latch extension 38 carried by the cap. Thus, a detent structure is feasible to maintain the nozzle head and piston assemblies in retracted positions if this is desired.
  • flared portion 13 in the retracted position of the piston device as shown in FIG. 4 flared portion 13 is below vent opening 36 allowing exterior air to pass through the cylinder and vent opening into the receptacle but when the piston device is in the projected position shown in FIG. 2 flared portion 13' is above the vent opening 36 preventing the passage of the receptacle content out of the receptacle through the vent opening and the cylinder.
  • Skirt 23 is between the vent opening 36 and the cylinder inlet at flared surface 29 in both the projected and retracted positions of the piston device, preventing passage of the content of the receptacle through the cylinder into v'ent opening 36.
  • an upper valve structure Adjacent the upper end of tube or neck 40, an upper valve structure is disposed which in this embodiment embraces the seat defined by the upper edge zone of the neck and with which a valve member 45 cooperates. That valve will have secured to it the upper end of rod 46.
  • a rod 52 may slidably extend therethrou-gh with ample clearance.
  • the upper end of extension 51 provides a valve seat 53.
  • Rod 52 is connected at its upper end with a valve body 54 which may simply be defined by a flared extension of rod 52.
  • a rubber sealing member 63 is provided.
  • Member 63 has not been shown in previous embodiments and consists of a cylindrical body portion 64, a peripheral outwardly directed flange 65 adjacent the upper surface of container 10.
  • Member 63 also has a lower inwardly directed shoulder 66 joining portion 64 and a portion of member 63 adjacent the outer wall of cylinder 22a.
  • the portion of member 63 in adjacency with the outer wall of cylinder 22a is indicated by the numeral 67 in FIG. 8 and the outside surface thereof is indicated by a numeral 68.
  • the surface 68 is exposed to the contents of container 10 and is angularly formed so that the portion bounded by surfaces 67 and 68 continually decreases in thickness as it moves away from the main body of member 63 providing a membrane.
  • An atomizer pump construction in accordance with claim 2 in which a rod is interposed between said first and second check valves which upon abutting said first check valve opens the same, and the distance between said first and second check valves is greater than the length of said rod in the first position of said piston assembly and less than the length of said rod in the second position of said piston assembly whereby one end of said rod abuts said second check valve and the remaining end of said rod abuts said first check valve opening the same.
  • An atomizer pump construction in accordance with claim 1 in which a resilient sleeve is provided surrounding the pump cylinder and said vent opening, said sleeve preventing any continuous flow of fluid through said vent opening into the cylinder and yielding outward to enable opposite fluid flow through said vent opening.
