Definitions

  • the field of the invention is apparatus for dispensing with a discharge assistant.
  • the present invention is particularly related to hand actuated dispensers which are screwed onto the tops of perfume bottles or other liquid containers where it is desired to dose, spray or atomize the contents thereof.
  • the state of the prior art dispensers is represented by German Patent 1,201,684, granted Jan. 29, 1964, German Utility Patent 1,920,632, granted Apr. 12, 1964, German Utility Patent 1,735,455, granted ' May 2, 1956, and French Patents 760,904 and 1,177,620, published Sept. 15, 1933 and June 28, 1957 respectively.
  • An object of the present invention is to provide a hand operated pump dispenser wherein the suction stroke commences without delay and immediately upon the release of the plunger.
  • a hand actuated simply operating push plunger pump with a compression spring in the pump cylinder is provided.
  • the spring presses against a valve plate of an outlet valve that is opened by means of a hollow plunger stem. While the pump is at rest the plate presses against a valve seat in a pump plunger.
  • a sealing sleeve is combined in the pump cylinder in a position between the plunger and the closure cap of the container. The sleeve is engaged, while the pump is at rest, by a plunger consisting of a cutf and a neck.
  • the pump cylinderv has a pressure equalizing opening which in the resting position is at the level of the space between the plunger cuif and the sealing sleeve whereby the air equalizing path is sealed off by the latter during the resting stage.
  • the inside of the container is kept in communication with the outside atmosphere.
  • a particular feature of the present invention comprises having the plunger connected by a thin walled elastic neck to the side of the plunger stem.
  • the pump of this invention is suitable for many purposes, e.g., for dosing, spraying and atomizing from suitable containers from which a liquid, e.g., a combustible volatile, etching or odoriferous liquid, either goodor bad-smelling, can be expelled.
  • a liquid e.g., a combustible volatile, etching or odoriferous liquid, either goodor bad-smelling
  • the pump of the present invention has important advantages over known pumps.
  • the compressed liquid in the cylinder 0pposes the downward movement of the plunger cuff so that the elastic neck portion thereof is compressed by continued downward movement of the valve stem.
  • the elastic neck portion Upon termination of the downward movement and release of the hand-applied pressure and escape of fluid from the cylinder into the plunger rod, the elastic neck portion forcibly engages the plunger cuff with the valve plate, thereby closing the outlet valve. Closure of the outlet valve occurs as soon as the hand applied pressure is released, regardless of whether or not the suction movement commences immediately. Complete suction action commences therefore immediately upon initiation of the suction movement.
  • the plunger neck is securely attached and sealed in an annular groove around the plunger rod.
  • This also has the advantage of keeping the connection between the plunger and the plunger rod permanently sealed. It is therefore not possible during the pressure stroke for any liquid to enter the space between the plunger neck and pump cylinder which would prevent such liquid from being ejected by the nozzle as happens with prior pumps under normal conditions.
  • the present construction also has other advantages.
  • the sealing sleeve is formed of rubber because in its resting position where is is continually under spring pressure, it is urged against an additional closure plate. It should be made of rubber so that it will resume its original form even after remaining for long periods of time under pressure. Rubber, however, has the disadvantage of deteriorating in the presence of various liquids, with loss of its original properties.
  • it is not only the construction that is greatly simplified (by the omission of the pressure plate), but it is also possible by choice of suitable materials for the sealing sleeve e.g., Teflon or polypropylene, to avoid chemical attack by various liquids thereon.
  • the use of a rigid material for the sealing sleeve also has the advantage that in the resting condition where the plunger cuff seats on the inner edge of the sleeve, the force of the spring is exerted only on the sleeve.
  • the plunger neck is therefore not under compression while in the resting condition so that even after remaining idle for a long period of time it does not lose its elasticity.
  • Another advantageous feature of the pump of this invention is that inside the pump cylinder in the region of the plunger cuff at the end of its compression stroke there is an annular enlargement in such a position that between the plunger cuff and the enlargement there is an annular slit with additional advantages.
  • an elastic expansion occurs, especially of the pump cylinder and plunger, as a result of the increased fluid pressure.
  • this expansion returns to normal with the fluid pressure diminishing only gradually. The result is that the expulsion of the liquid occurs only gradually.
  • This is, however, a disadvantage for pumps that are to be used for different purposes. If, for example, the pump forms part of an atomizer, droplets of liquid will then remain on the nozzle after each operation which are undesirable.
  • FIGURE 1 shows the pump in its stationary condition
  • FIGURE 2 shows the pump at the end of its forward stroke.
  • the inlet valve is shown in the form of a ball valve 2.
  • the strong pressure spring 3 presses directly against the valve plate 4 which is fastened to the lower end of the plunger rod 5 and presses against a plunger 6a, 61: mounted on the plunger rod.
  • the plunger consists of a cuff 6a and a neck 6b, the latter being firmly seated in an annular groove 5a in an enlarged portion 5b of the plunger rod 5.
  • a sealing sleeve 7 of rigid material is pressed down to a depth limited by the flange 8.
  • the sealing member 9 forms a seal between the pump cylinder 1 and the opening of the container 12.
  • a pressure equalizing opening 10 is formed in the wall of the pump cylinder 1 to keep the pressure in the container 12 equal to that of the atmosphere, and also to return to the container any leakage liquid from the cylinder.
  • the lower end of the plunger has a transverse bore 11 to permit liquid to enter the bore 15 in the plunger rod 5 when the outlet valve is open.
  • the inner wall of the pump cylinder is enlarged in the region of furthest downward movement of the plunger cuff 6a.
  • the pump carries a closure cap 13 for mounting it on the container 12.
  • the lower end of the sealing sleeve 7 presents an edge 14 against which the plunger cuff 6a is pressed while the pump is at rest.
  • the plunger rod 5 carries at its upper end an actuating head 16 to the side of which an atomizing nozzle 17 is fastened.
  • the compression spring 3 presses the valve plate 4 against the plunger cuff 6a to urge the latter against the inner edge 14 of the sealing sleeve 7.
  • the effect of this is on the one hand to close the fluid passageway through the outlet valve formed by the valve plate 4 and the plunger cuff 6a to the bore 15 in the plunger rod 5, and on the other hand the engagement of the plunger cuff 6a with the inner edge 14 of the sealing sleeve 7 prevents the liquid from escaping through the air pressure equalizing opening 10, along the sealing sleeve 7 and through the slit between plunger rod 5 and the closure cap 13.
