Definitions

  • ATOMIZER PUMP Filed Jan. e, 1966 A 2 sheets-sheen 1 hnl ATTOR N EY5 April 23, 1968 R. DECAUX ATOMIZER PUMP 2 Sheets-Sheer 1 Filed Jan.
  • the present invention relates to improvements to atomizers of the kind which are normally used for perfume or to vaporize beauty products or drugs or dressings.
  • Atomizers of good quality tas presently known include generally .a moving cap which is pressed in an alternating movement in order to expel the vaporized liquid through a nozzle situated in this cap.
  • This kind of apparatus presents three major disadvantages, that is to say The cap is not tixed against rotation in relation to the container so that it can turn, as can, in consequence, the vaporized jet;
  • the jet is subject to the same alternating movement as the cap;
  • the present invention has the main purpose of avoiding these disadvantages by designing an atomizer with a pump which is effectively sealed, and of which the jet occupies a fixed position in relation to the bottle or the body of the container holding the liquid to be vaporized.
  • the assembly according to the invention is very simple and may be manufactured at low cost.
  • atomizing mechanism primarily for scent sprays of the kind comprising a pump which draws in and expels and which is operated by a cap or the like on which one can press with the finger, has a body adapted to be secured on the neck of a container and has an axial bore with an intake valve at its base in communication with the interior of the container, a piston being slidable in the said bore, the piston having a push Fice rod mounted on an upper skirt in which is tted a tubular sleeve smaller in diameter than the said bore and having a lower skirt, an output valve being interposed between the interior of the lower skirt and the interior of the tubular sleeve, a spring ybeing provided for the return stroke of the piston after it has been moved by pressure applied to the push rod, the interior of the tubular sleeve communicating with the lower part of the said bore by way of the output valve and also with Ian annular intermediate space surrounding the sleeve by way of an aperture in the wall of the sleeve, the lower skirt
  • a side port of which the height, measured parallel to the axis of the mechanism, will be closely equal to the distance which the skirt must slide touncover the apertures feeding the nozzle.
  • the pump is thus lassured of a very smooth action from the beginning of the movement of the piston.
  • a mechanism according to the invention ensures sealing in close proximity to the nozzle, which reduces practically -to zero the quantity of liquid which is liable to leak towards the exterior when the atomizer is inverted during transport-ation. It is to be noticed, finally, that this sealing is ensured by the pis-ton itself, without having recourse to special sealing devices: there results from this ya great simplicity of construction, and low cost in production.
  • FIGURE l is ra sectional view of an atomizer according to the invention.
  • FIGURE 2 is a sect-ion -along the line II-II of FIG- URE l, but drawn to a larger scale,
  • FIGURE 3 is a section along the line IIL-III of FIGURE 2,
  • FIGURE 4 is a view similar to FIGURE 1 but illustrating a modification
  • FIGURE 5 is a view similar to FIGURE 4 but showing the atomizer in use
  • FIG. 6 is a section along the line VI-VI of FIG- URE 4.
  • the atomizer includes a xed body 1, which is attached by any known method onto the neck of a ask or reservoir 2.
  • the assembly may be carried out for example, as shown, by means of a threaded cap 3 which is screwed onto the ask.
  • the body 1 includes throughout its height an axial bore 4, of which the lower extremity ends at a non-return valve 5, communicating with the upper end of an intake tube 6 which extends downwardly in the conventional rnanner into the liquid 7 to be vaporized.
  • the valve 5 may comprise a ball which falls onto its seating by gravity. Without going beyond the sco-pe of the invention, this valve 5 could obviously be replaced by any other known system, and in particular by providing above the ball a special return spring.
  • a coil compression spring 8 is mounted so as to bear on a base shoulder 9.
  • the upper end of the spring 8 is fitted within the skirt 10 of a piston A the upper end of which is engaged by a cap 11 for displacing the piston A against the action of the spring 8, for example, 'by pressing the cap with the finger.
  • This piston A includes a central tubular sleeve 12, of which the exterior diameter is less than the diameter of the bore 4, and which attaches the lower skirt 10 to a push rod 13 fixed to the cap 11.
  • the lower skirt 10 does not make a tight fit within the body 1, permitting a minior flow of uid suicient to prevent a hydraulic block.
  • This push rod 13 ends in a skirt 14 sealing around its circumference which encloses the upper part of the tubular sleeve 12.
  • This skirt 14 may be identical with the skirt 10, and both are preferably made of plastic or of any other material sufficiently elastic to give them a radial pressure against the internal wall of the bore 4.
  • the bottom of the sleeve 12 communicates with the interior space of the skirt 10, by means of a ball valve 15, which constitutes the output valve of the pump thus created.
  • the valve 15 may be of any known type, and in particular may possibly include a special return spring.
  • the side wall of the body 1 of the atomizer is pierced by one or several fine radial perforations 16, which open into a vaporizing nozzle B which is shown in detail in FIGURES 2 and 3.
  • These perforations 16 open into the interior of the bore 4 at a level such that they are uncovered by the sealing skirt 10 when the piston A has already been displaced towards the base a certain distance, so as to meet the spring 8.
  • the nozzle B is preferably made -up of a at circular face 17, machined on the side of the body 1, and surrounded by a cylindrical groove 18, which allows it to be capped by a capsule 19 which is pressed on.
  • this capsule 19 is perforated in its centre 'by a jet 20 which opens towards the interior by a conical chamfer.
  • This jet 20 faces a circular hollow 21 provided in the centre of the flat face 17.
  • the perforations 16 open on the fiat face 17 at two points diametrically opposed on each side of the hollow 21.
  • the communication between this latter and each perforation 16 is assured by means of a channel 22 :formed by engraving on the face 17.
  • the two channels 22 are symmetrical with regard to the centre of the hollow 21. and each one of them is made following a curved prole which permits it to open substantially tangentially into the said hollow 21.
  • a lateral perforation 26 puts the interior of the sleeve 12 in communication with the intermediate annular space which surrounds it in the bore 4. This perforation 26 opens below skirt 14.
  • flange 24 below which au internal annular nib 25 formed in the cap 11 engages.
  • the flange 24 and the nib 25 may be replaced by an other known means of check or stop, for example, by a transverse pin, or similar device.
  • the skirt 10 When the piston A arrives at the end of its travel, the skirt 10 likewise uncovers the aperture 23 which thus communicates directly with the perforations 16 ⁇ and allows the surrounding air to penetrate to the interior of the container 2, to compensate for the volume of the liquid atomized. This entry of air is made by intake through the nozzle B, which eliminates all trace of weeping which there might be a tendency to produce.
  • AIt may be seen moreover that the body 1, and in consequence the spray 27, may be positioned at will in relation to the container 2 before the cap 3 is fixed, which is of special advantage when the form of the said container 2 is not round, particularly if it is attened.
  • the body 1 includes a lateral port 30 formed through the wall of the bore 4 within which the skirt 10 of the piston A slides.
  • the upper edge of this port 30 is level with the lower edge of the skirt 10 when the assembly is in the rest position (FIGURE 4).
  • the height 31 (FIG. 5) of the port 30, measured in an axialy direction, is closely equal to the distance 32 (FIG. 4) which separates the upper edge of the skirt 10 and the perforatious 16 provided to feed the nozzle B, at the level where they open into the bore 4.
  • the perforations 16 were inclined downwards, for example in order to reduce the height of the atomizer. It is perfectly obvious that the port 30 could be calculated in the same way if the perforations 16 were arranged horizontally as illustrated in FIGURE 1.
  • the piston A rises again under the return action of the spring 8.
  • This piston starts by taking in liquid through the valve 5 Which lifts, and this intake continues until the skirt 10 uncovers the port 30 in the course of its rise. Meanwhile, a new charge of perfume has been transferred above the valve 5.
  • the port 30 may be arranged so as to open above the upper edge of the skirt 10 when this latter is fully depressed (FIGURE 5 which puts the perforations 16 directly in communication with the interior of the ask 2 and allows the air-entry opening 23 shown in FIGURE l to be omitted. In all cases, the entry of air is made through the nozzle B.
  • a radial lug 34 which is intended to fit a correspondingly profiled recess or seating provided in the open top of the cap 3 (FIGURE 6). This latter is thus fixed angularly to the body 1 which may be used to screw it on or off.
  • Atomizing mechanism principally for scent sprays, comprising a body, means mounting said body on the neck of a container, an axial bore in said body, a valve in the base of said bore for communication with the interior of said container, a piston slidable in said bore, said piston comprising a push rod having an upper skirt, a tubular sleeve fitted in said upper skirt and a lower skirt on said tubular sleeve, the external diameter of said tubular sleeve being less than the diameter of said bore to leave an annular space between said sleeve and said bore, an output valve providing communication between the interior of said sleeve and the base of said bore and an opening in the wall of said sleeve communicating between the interior of said sleeve and said annular space, an atomizing nozzle on the outside of said body, feed channels in said body communicating between said nozzle and said bore and disposed to be uncovered by said lower skirt of the piston on downward movement of the latter, and spring means urging said piston upwardly.
  • Atomizing mechanism as defined in claim 1, comprising a lateral opening in said body and communicating between said bore and the interior of said container and disposed to be uncovered by the lower skirt of said piston when the latter is displaced downwardly, the inner ends of said feed channels of the nozzle and also said lateral opening being disposed between the upper and lower- Skirts when said piston is in its downward position.
  • Atomizing mechanism as dened in claim 2 in which the height of the said lateral opening measured parallel with the axis of the mechanism is substantially equal to the distance through which the lower skirt must slide in the downward direction to uncover the feed channels of the nozzle.
  • Atomizing mechanism as defined in claim 1, in which said lower skirt of the piston completely seals said feed channels of the nozzle in close proximity to the latter when the atomizer is at rest with said double skirt in its upper position.
  • Atomizing mechanism as defined in claim 1, comprising a screwed cap retaining said body on the neck of the container a radial projection on said body and a recess in said cap, said radial projection engaging in said recess.
