Definitions

  • This invention relates to liquid atomizers and particu larly to atomizers driven by an alternating pump.
  • the present invention especially, but not exclusively, concerns atomizer pump units adapted to be operated manually by the user and to be mounted as the cap for a essel containing the liquid to be atomized.
  • Yet another object herein is to facilitate the utilization of such atomizers.
  • the present invention is intended to be employed in an atomizer assembly having a pump comprising an alternating element to be operated by the user and a restoring means for returning, and maintaining, the element in its rest position.
  • the novel concept of the invention rests in causing this element, when in its rest position, to break the communication between the pump work chamber and the pump outlet valve, and, preferably, in attaching to the wall of said chamber an element capable of yielding elastically in such a way as to ensure the reestablishment of the communication between the chamber and the valve when the alternating element is moved away from its rest position.
  • the present invention also consists in several other features which will be discussed in detail below.
  • the invention concerns not only the abovedescribed device, but also its application to containers for dispensing various types of cosmetic and medicinal liquids.
  • FIG. 1 shows a longitudinal cross-sectional view of one preferred embodiment of the present invention in its rest position
  • FIG. 2 is a view similar to that of FIG. 1 showing that Patented June ill, 1968 embodiment in its position corresponding to the end of its compression motion;
  • FIGS. 3 and 4 show views similar to those of FIGS. 1 and 2, respectively, of a second embodiment of the present invention.
  • FIGS. 5 and 6 are correspondingly similar views of a third embodiment thereof.
  • each of the illustrated embodiments of the present invention are shown, only for exemplary reasons, in the form of a unitary assembly of an atomizer pump and nozzle arrangement forming a part of a threaded cap designed to fit tightly on the top of a suitable container, such as a bottle or can, having any neck diameter, since the cap can easily be made to any size.
  • a suitable container such as a bottle or can, having any neck diameter
  • the cap can easily be made to any size.
  • the structure of the present invention can be used as easily in connection with wide-neck bottles as with those of the narrow-neck variety.
  • the alternating pump is constituted by a cylinder 1 within which travels a plunger 2.
  • a downward pressure exerted by the user on a control push button 3 urges plunger 2 in a direction to drive fluid out of the volume In enclosed by the lower portion of cylinder 1.
  • This movement of plunger 2 also serves to compress a restoring spring 4, placing said spring in a condition to force plunger 2 out of volume la when the user releases button 3.
  • This upward movement creates a partial vacuum in volume 1a which acts to lift ball valve 5 away from its seating and to draw liquid from tube 5a into volume 1a.
  • Tube 5a is an immersion tube whose length is such that its lowest end rests very close to the bottom of the container to assure that all of the liquid in the container will eventually be drawn into volume 111.
  • the bottom of spring 4 is supported by a washer which may rest on a screen 18 serving to limit the movement of ball valve 6.
  • cylinder 1 The upper end of cylinder 1 is extended by a coaxial, larger-diameter portion 7 enclosing a bowl-shaped volume 7a.
  • Cylinder 1 and plunger 2 are also joined together by a roughly annular flexible membrane 8 which may be made of rubber or any other material having similar mechanical properties.
  • the inner edge of membrane 8 is attached to plunger 2 by being mechanically gripped, for example, between a shoulder on the upper end of said plunger and the lower edge of a sleeve 2a of rigid material which forms an element for transmitting to plunger 2 the depression force exerted by the user on button 3.
  • the outer edge of membrane 8 is attached to cylinder 1 by being tightly gripped between the outer circumference of portion '7 and a retaining collar.
  • the space 7a communicates with the space 1a through the annular passage resulting from the play existing between plunger 2 and cylinder 1.
  • the pump work chamber is thus constituted by these two spaces and has a maximum volume when plunger 2 and membrane 8 are in their rest position, as shown in FIG. 1.
  • Plunger 2 has an upper portion containing a fluid passage 9, 9a communicating with work space 7a through a radial groove in said plunger shoulder and serving as the pump outlet passage.
  • the outlet end of this passage is covered by a one-way outlet valve 6 which is normally ur ed the-reagainst by a spring 13.
  • One of the basic concepts of the present invention is to provide means which tightly closes the fluid path between work space 7a and outlet valve 6 when the pump is in its rest position, thereby assuring that the container on which the atomizer is mounted, as well as the pump work spaces, will not be subject to any fluid leakage.
  • this means is constituted by a portion of membrane 8 which bears against a disc it of plunger 2 when the latter is in its rest position. It should be noted that this membrane forms one boundary of the pump work space and also encloses the fluid-receiving end of passage 9, 9a.
  • the communica' tion between passage 9:: and work space 7a is controlled by the relation between the membrane and the disc 19 which is rigidly mounted on plunger 2.
  • the cap containing the pump and adapted to close the container comprises an outer shell constituted by a cylindrical wall 19 and an annular top 1]. in which is formed an axial opening 11a for the passage of sleeve 2a. Opening 11a is of slightly smaller diameter than disc 1%; hence, top 11 serves to determine the rest position of plunger 2 and acts to force membrane 3 against disc 18, thus assurin the creation of a seal between the latter two elements.
  • the remainder of the cap is constituted by an insert consist'ag of a cylindrical lateral portion 26 having raised cont? tor-engaging threads therein, and an annular top 23 having a central openin 21 therein through which passes cylinder 1.
  • This open serves as the outlet end for an air passage constituted by a radial passage 23a in top 23 communicating with a longitudinal slot 24 (left side of drawings).
  • the inlet end of this passage communicates with the outside air through opening 11a and thereby permits air to enter the container at a rate equal to the rate at which liquid is dispensed. Air may enter whenever membrane 8 is not blocking opening 11a, i.e., whenever the pump is not in its rest condition.
  • membrane 8 acts to prevent nuid from escaping either from space 7a or rom the abovedescribed air passage.
  • Such an arrangement for closing the air passage is described in detail in applicants French Patent No. 1,339,657 filed on Aug. 30, 1962.
  • Push button 5 is rigidly mounted atop sleeve 2:; and comprises a fluid outlet path consisting of a vertical passage 14 aligned with the fluid passage through sleeve 2a, a radial passage 15 communicating with passage 1 an atomizing nozzle 16, and, in the embodiment of FIGS. l and 2, a helical passage 17 connecting passage 15 to nozzle 16, the shape of passage 17 be'ng chosen to give a rotation to the atomized spray.
  • the above-described device b gins its cycle of operation in the position shown in FIG. 1, with a quantity of liquid held in volume ta.
  • the user depresses push button 3, thereby moving plunger 2 downward through the intermediary of sleeve 2:: and against the action of restoring spring
  • the start of this downward movement deflects membrane 8 suificiently to open both the above-described air-inlet passage and the fluid passage between volume 7a and passage 9, t er. Both passages will remain open during the complete cycle of operation of the pump, until plunger 2 returns to its rest position.
  • Valve 6 is provided with a radial passage which assures that a fluid fiow path will remain between passaegs 9 and 14 even if valve 6 is forced into its uppermost position, as shown in FIG. 2.
  • the fluid is forced through passages 14, 15 and 1'7, being accelerated considerably in this latter passage due to the small cross-sectional area thereof, and emerges from atomizing nozzle 16 as a line spray.
  • FIGS. 3 and 4 there is shown a secand proposed embodiment of the present invention in which elements identical with corresponding elements of FIGS. 1 and 2 are given the same reference numerals while elements which are the functional equivalents thereof are given the same number indiced, The same procedure will be followed for FIGS. 5 and 6.
  • FIGS. 3 and 4 to be in its rest position and at the end of compression travel, respectively, difiers from that of FIGS. 1 and 2 only in the structure of plunger 2 button 3 valve 6 and membrane 8 and in the elimination of sleeve 2a, spring 13, and helical passage 17, the latter two elements being merely optional features in any device of this type.
  • Plunger 2 is shorter than plunger 2 and does not re quire a disc such as disc it].
  • passage 9a and the lower end of passage 9 are placed in a slightly lower position than in FIG. 1.
  • Membrane 8 is almost identical with membrane 8, except that the former carries a downwardly-directed tubular rubber sleeve 8:: which is sufficiently co-extensive with plunger 2 to pass beyond passage 9a.
  • Sleeve 8a acts, in cooperation with membrane 3 in such a way as to seal the end of passage 9a, thus breaking the communication between this passage and volume 7a, when the pump is in its rest position (FIG. 3) and to open passage 9a when the pump is in any other position (e.g. FIG. 4).
  • this sleeve performs the function previously carried out by the cooperation between disc 1d and membrane 8.
  • Button 3 is formed with a hollow downwardly-directed extension into which the upper end of plunger 2 fits.
  • the lower rim of this extension cooperates with a shoulder on plunger 2 to grip the inner edge of membrane 8
  • the top of button 3 has a depression which serves as a finger grip.
  • Valve 6 is in the form of a ball which is the functional equivalent of the valve 6 of FIG. 1.
  • membrane 8 may be made slightly thicker than membrane 8.
  • FIGS. 3 and 4 functions in exactly the same way as that of FIGS. 1 and 2.
  • FIGS. 5 and 6 there is shown a third embodiment of the present invention which differs from that of FIGS. 3 and 4 chiefly in the position of passages 9 and 9a and in the provision of an annular seal 12.
  • Seal 12 is mounted on cylinder 1 at the bottom of the large-diameter portion thereof, in such a way as to serve as a boundary between volume in and volume 7a.
  • this large-diameter portion may be made of two annular portions the inner one of which is positioned after seal 12 has been put in place in such a way as to grip the outer portion of this seal.
  • the lower portion of plunger 2 up to passage 9a has a diameter sufiicient to form a fluid-tight fit with seal 12 when the pump is in its rest position.
  • the plunger region above passage 9a has a reduced diameter which assures that passage 7a will communicate with volume in through space 12:: when the plunger leaves its rest position. If desired, the same result could be obtained 'by not giving this latter region a reduced diameter, but by providing a longitudinal groove on the plunger surface extending upwardly from passage 90.
  • Passage 9 is placed to be just even with, or slightly above, seal 12 when plunger 2 is in its highest, or rest, position.
  • an atomizer pump designed to be mounted on a container of liquid to be atomized and comprising a cas ng for red by a top end wall and a cylindrical skirt riding downwardly from said top end wall, a cylinder carried by said casing coaxially on the inside thereof so as to extend into said container, at check valve in said cylinder opening in the upward direction, a plunger slidable in said cylinder so as to be movable between two positions, a bottom one and a top one, said top position being the rest position of said plunger, said plunger being provided with a liquid passage extending therethrough from the inside of said cylinder, a push-piece rigid with said piston slidable with respect to said casing, said pushpiece being provided with a discharge nozzle in communication with said passage, a check valve in said passage adapted to open outwardly, a flexible fluidtight annular membrane having its outer edge secured in a iluidtight manner to said cylinder and its inner edge secured in a fiuidtight manner to said plunger
  • said passage has its inlet end opening into the side wall of said plunger, under said membrane inner edge, and
  • resilient means fixed to said cylinder are provided to cooperate with said plunger for cutting off communication between said passage and the inside of said cylinder when said plunger is in its rest position.
  • said resilient means consist of a portion of said membrane surrounding said inner edge thereof, said plunger including a disc located just under said passage inlet end and adapted, when said plunger is in its top position, to pinch said membrane against said casing top end wall.
  • An atomizer pump according to claim 1 wherein said resilient means consist of a downwardly extending sleeve integral with said membrane and adapted to fit on the periphery of said plunger at the height of said passage inlet end when said plunger is in its top position, thus stopping said passage, and to be deformed away from said plunger so as to clear said passage inlet end when said plunger is moved downwardly from its rest position and said membrane is correspondingly deformed.
  • said resilient means consist of a sealing annular member of resilient material fixed at its outer edge to said cylinder and the inner edge of which is slidably applied against the periphery of said plunger, the outer wall of said plunger being shaped to fit tightly against said annular member inner edge when said plunger is in its top position and to leave a passage between itself and said annular member inner edge when said plunger is moved downwardly from said top position.
