Definitions

  • the invention relates to a precompression system for placing between a pump and a discharge nozzle, according to the preamble of claim 1.
  • a precompression system for placing between a pump and a discharge nozzle, according to the preamble of claim 1.
  • Such a precompression system is known from the document US 5.641.957.
  • US Patent No. 5,730,335 shows another type of precompression system.
  • a sprayer head for a container, for instance a bottle containing liquid detergent.
  • a sprayer head is formed by a body in which a manually operable piston pump is arranged.
  • This pump is operated by a trigger that is pivotally connected to the body.
  • the suction side of the pump is connected to a tube that extends into a bottle over a substantial length, usually nearly to the bottom thereof, and through which liquid may be drawn out of the bottle.
  • the compression side of the pump is connected to the discharge nozzle of the sprayer head through a conduit.
  • the precompression system comprising a precompression valve that is kept shut by spring means and that is opened only when a predetermined pressure is attained within the pump.
  • the precompression valve has for its object to prevent the fluid from leaving the discharge nozzle at too low a pressure, which would result in too large drops being formed in the spray.
  • the liquid In order to achieve an optimum spraying pattern the liquid must in fact be pressed out of the discharge nozzle at a predetermined and relatively high pressure.
  • the known precompression system comprises an end part of the cylinder wall of the pump, which debouches in an annular space.
  • the rim of the cylinder wall constitutes a seat onto which a resiliently flexible diaphragm is pressed.
  • This diaphragm is pressed shut by spring pressure, which in the diaphragm of this older patent is generated by the flexion stresses in the material of the diaphragm itself.
  • the pressure in the pump cylinder becomes high enough the diaphragm will be lifted from the seat whereby pressurized liquid may flow from the cylinder to the conduit leading to the discharge nozzle.
  • the diaphragm will return to the closing position in which it comes to rest against the seat again as a result of the internal spring force.
  • the known precompression system has the drawback that the annular space is arranged in-line with the pump cylinder. It is therefore difficult to design this known precompression system such that it can be manufactured by injection molding, and furthermore the resulting design becomes relatively bulky, thus making it hard to incorporate in a compact sprayer head.
  • the pump incorporating the precompression system is arranged under an angle between the suction tube and the spraying tube for manufacturing reasons, which results in a complex structure that is hard to assemble.
  • the invention therefore has for its object to provide a precompression system of the type described above, which is easier to make and assemble than the conventional precompression system, and which therefore offers a greater freedom of design when integrating it into a compact sprayer head. This is achieved with the precompression system of claim 1.
  • the invention further relates to a spraying device comprising a pump having a suction side and a compression side, means connected to the suction side of the pump for supplying a fluid to be sprayed, a discharge nozzle connected to the compression side of the pump and a precompression system of the type described above arranged between the pump and the discharge nozzle.
  • the invention relates to an assembly constituted by a container and a spraying device as described above.
  • a sprayer head 1 for a container 2 comprises a pump 3 having a suction side 5 and a compression side 6.
  • Movable operating means 4 are connected to the pump 3, in the illustrated example constituted by a trigger 13 having a continuous pivot shaft 53 that is received in a hollow space 54 in a frame 22 carrying the pump 3 and that is locked therein by a flexible snap arm 55.
  • Means 7 are connected to the suction side 5 of the pump 3 for supplying a fluid from the container, comprised of a conduit having its free end connected to a tube 23 extending into the container.
  • the compression side 6 of the pump 3 is connected to a discharge nozzle 8 through a conduit 9.
  • an aperture 56 is arranged in the trigger 13, through which extends the end of this conduit 9, onto which is arranqed the discharge nozzle 8.
  • Pump 3 is a piston pump, constituted by a pump housing or cylinder 10 and a piston 11 reciprocating therein.
  • the piston 11 is connected to the trigger 13.
  • the sprayer head 1 comprises biasing means 16.
  • the biasing means are constituted by a pair of parallel flexion springs 17 that engage ribs at the inside of trigger 13.
  • the connection between the trigger 13 and the piston 11 is a snap connection formed by protrusions 14 of the trigger 13 being snapped into corresponding openings 28 in the piston 11.
  • a precompression system comprising a space 58, which in the illustrated embodiment is annular, connected to the cylinder 10 and an end part of the spraying conduit 9 debouching therein, which are closed off in a gas- and liquid-tight manner by a resiliently flexible domed diaphragm 59.
  • the space 58 is bordered by a cylindrical sleeve 60 that is received in a cavity 61 in the frame 22 and that is integrally formed with the diaphragm 59 in the illustrated embodiment.
  • an opening 15 is formed, in which is arranged a valve, and which is connected to the suction tube 7 for the fluid through an opening 67 in the frame 22.
  • This valve 63 which is also integrally formed with the sleeve 60, is movable, in the shown embodiment pivotable between a position in which it hermetically seals the opening 67 (Figs. 3, 4, 6A) and a position in which this opening 67 is left clear (Fig. 5, 6B). Further a stop member 64 is connected to the diaphragm 59, which serves to limit bending of the diaphragm 59 and to prevent it from "flipping over”.
  • the cylindrical sleeve 60 is locked in the cavity 61 of the frame 22 by an end wall which in the shown embodiment is integrally molded with the container 2.
  • the cylindrical sleeve 60 further includes a reinforcing flange 75 by which deformation of the sleeve 60 under the influence of the pump pressure in the cylinder 10 and thus the risk of leakage along the sleeve 60 is prevented.
  • the shut off valve 63 is connected to the cylindrical sleeve 60 by means of a pair of pivotable and stretchable f -shaped arms 68 having one end 69 attached to the sleeve 60 and the other end connected to the valve body 63.
  • the arms 68 are pivoted upward and stretched somewhat, whereby the valve body 63 is lifted from the opening 67 over a height L.
  • the cylindrical sleeve 60 does not include an opening which is connected to the suction tube 23. Instead the sleeve 60 has a slightly outwardly extending peripheral edge part 70 close fittingly lying against the wall of the cavity 61.
  • the peripheral edge portion 70 is relatively flexible and includes a slightly inclined inner surface 73.
  • the sleeve 60 further includes a part 71 having a reduced diameter and bordered on one side by the flexible edge part 70 and on the other side by the cylindrical part of the sleeve 60. Together with the wall of the cavity 61 the reduced diameter part 71 defines an annular space 72 which is in fluid communication with the opening 67.
  • the peripheral edge part 70 functions as a valve having excellent sealing properties. Due to the sealing action of the peripheral edge part 70 the pump pressure does not act on the cylindrical part of the sleeve 60, so that the risk of leakage of fluid along the cylindrical part and the annular sealing ridges 74 connected thereto is reduced. Furthermore the sleeve 60 may be constructed smaller and less heavy than in the previous embodiments, as there is no need for a reinforcing flange along the peripheral edge. Furthermore this embodiment of the sleeve 60 may simply be manufactured by means of injection moulding, as the elimination of an opening in the side wall and the corresponding valve has for its result that there is no need for slides or mandrels in the mould. Finally, the sleeve 60 may also be installed more easily, as it is wholly symetrical in rotational direction around the center line, and lacks an opening that should be aligned with the opening 67.
  • peripheral edge part 70 of the sleeve 60 is not critical, as the sole requirement is that it should exert sufficient pressure on the wall of the cavity 61 to ensure a perfect sealing during a pump stroke, and should be lifted from the wall at any point along its periphery during a suction stroke.
  • shape of the edge part 70 and of the wall should further be selected such, that they define an annular space. Therefore, the angle of inclination of the peripheral edge part is somewhat smaller in an alternative embodiment (fig. 9), whereas the wall of the cavity has a larger inclined part, leading to substantially the same volume for the annular space 72.
  • the precompression system 40 serves in known manner to inhibit transport of fluid from the container 2 to the discharge nozzle as long as a predetermined pump pressure is not yet attained. If a fluid is sprayed through the nozzle 8 at too low a pressure, this fluid is insufficiently atomized and drops generated in the spray cone are too large.
  • the connection between the container 2 and the discharge nozzle 8 is closed off by the diaphragm 59 which is forcibly pressed against the rim 66 of the spraying conduit 9 serving as a seat due to the internal stress determined by the domed configuration and assisted by the ambient pressure behind the diaphragm 59- Only when sufficient pressure, for instance on the order of 3 bar, is built up in the cylinder 10 by moving the piston 11 to its end position will the diaphragm 59 be lifted from the seat 66.
  • the sprayer head 1 thus functions as follows.
  • a user wishes to atomize the fluid from the container 2, he first pulls the trigger 13.
  • air that is present in the cylinder 10 and that cannot flow back to the container 2 due to the opening 67 being shut off by the valve 63 is compressed by the piston 11.
  • the pressure of the air is high enough at the end of the pump stroke the diaphragm 59 is lifted from the seat 66 and the air may escape.
  • annular space 58 is connected to the pump cylinder 10 and the conduit 9 debouching therein is connected to the discharge nozzle, instead of the other way around as in conventional precompression systems, the annular space 58 need not be aligned with the cylinder 10, but may be offset as illustrated.
  • the sprayer head may thus be efficiently manufactured by injection molding so that the design may be kept compact.
