Definitions

  • This invention relates to sprayer assemblies of the type that are attachable to a container of liquid to be sprayed over a mouth opening of the container, and when thus attached are operable, as with a push-button, to discharge a spray of the liquid from a spray nozzle of the assembly.
  • a sprayer assembly of the kind to which the invention relates has a store of pressure gas, e.g. air, connected thereto.
  • Means are provided whereby operation of the push-button or other manual control simultaneously establishes a gas owpath from said gas store to the interior of the liquid container so as to apply a gas pressure to the free surface of said liquid, and establishes a liquid owpath from the interior of the body of liquid in the container to the spray nozzle; hence operation of said push-button or the like results in a discharge of liquid from the spray nozzle due to the action of the gas pressure on the store of liquid.
  • pressure gas e.g. air
  • a more specic object is to provide means in such a sprayer assembly whereby actuation of the manual control, eg. button, will only be required to establish the above-mentioned liquid flowpath, while the gas ilowpath is automatically and permanently established on attachment of the sprayer assembly to a container.
  • a sprayer assembly for attachment to a liquid container said assembly comprising a reservoir containing a store of gas under pressure; a spray outlet nozzle; means defining a gas owpath from a point of said reservoir within said store of gas to a point of said container above a store of liquid contained therein, and means deining a liquid flowpath from a point of said container within the store of liquid to said spray nozzle; first means sealing said gas flowpath and second means sealing said liquid flowpath; means automatically actuable on attachment of the assembly to a container for disabling said rst sealing means to establish said gas ilowpath thereby to apply gas pressure to said store 'of liquid, and means manually actuable for disabling said second sealing means to establish said liquid flowpath thereby to discharge a spray of liquid from the nozzle under the action of said gas pressure.
  • the means for sealing the gas flowpath comprise a valve including a valve head, means such as a spring normally biasing the valve head into sealing engagement with a valve seat, and a stem extending from said valve head for actuation by an upper surface of a container neck on attachment of the sprayer assembly to the latter so as then to displace the valve head from said valve seat and thereby establish permanently said gas owpath.
  • FIG. 1 is a vertical cross sectional View of a liquid container, such as a flask or phial, having a sprayer attachment according to the invention screwed over the neck of it;
  • FIG. 2 is a cross sectional view of the sprayer attachment of FIG. l partly broken away, also showing the neck portion of the container on which it is attached, the View being taken on line II-II of FIG. 1;
  • FIG. 3 is a generally similar view to FIG. 2 but showing the sprayer attachment of the invention separate from the container, e.g. prior to attachment thereto.
  • the sprayer attachment of the invention is shown as comprising a sleeve or skirt 1 closed at its upper end and having a generally cylindrical body or plug member 2, conveniently made of a plastic, press-tted therein.
  • the body member 2 has a screw-threaded recess 2a formed in its lower end to enable the attachment to be screwed over the complementarily-threaded neck 3 of a ask 4 containing a liquid to be sprayed.
  • an annular seal 5 Interposed between the adjacent surfaces of body member 2 and the top surface of the neck 3 is an annular seal 5 which in addition to its sealing function serves as a spacer for a purpose later described.
  • a tank or reservoir 6 of pressure gas eg. air
  • a tank or reservoir 6 of pressure gas eg. air
  • a nozzle 7 (see FIG. 2). Also formed through the member 2 and a wall of the skirt portion ofthe assembly in a direction at right angles to the axis of the nozzle 7, is a bore 11 having a frustoco-nical intermediate portion interconnecting a smaller and a larger-diameter cylindrical portion, as willl be apparent from FIG. l.
  • a push-button member 12 Slidably mounted in this bore is a push-button member 12 which has a main part slidably fitting the smallerdiameter part of the bore 11 and a frustoconical rear end part 12a tting into the frustoconical part of said bore.
  • a compression spring 13 seated in the largerdiameter part of the bore 11 serves to bias the pushbutton member 12 to a projected position in which the rustoconical part 12a is abuttingly seated against the frustoconical part of the bore 11.
  • a duct 8 (FIG. 2) formed through body or plug member 2 in axial alignment with the nozzle 7 connects the nozzle with the intermediate frustoconical part of the bore 11.
  • a dipper tube 10 has its upper end secured around a boss projecting from the center of the under side of the body member 2 and extends down into the ask 4 to a point near the bottom of it.
  • the frustoconical sealing part 12a of the push-button member disengages the frustoconical wall of the bore 11 and thereby provides an annular gap through which the said ducts 8 and 9 communicate, to provide a path of discharge for the liquid contents of the flask from nozzle 7 in the form of a spray, as will be presently explained.
  • the recessed bottom Wall of the gas reservoir or tank 6 carries a riser tube extending upward to a point near the top of the tank, and connecting in aligned relation with a vertical bore 14 formed through the center of the embossed top part of the sprayer head 1.
  • the lower end of the bore 14 opens into a shallow recess 15 formed in a central area of the uppermost surface of the plug or body 2.
  • the shallow recess 15 connects near one side of it with a valve chamber 16 formed in the body member Z.
  • Chamber 16 at its bottom connects by way of a frustoconical valve seat with a vertical duct 17 formed through the plug member 2, and opening at its lower end within the gap delined between the under surface of the body member 2 and the top surface of the ask owing to the insertion of the annular spacer seal 5.
  • a continuous flowpath for gas is seen to be provided from the interior of gas tank or reservoir 6 to the space within the annular seal 5, the llowpath including the riser tube in the tank, duct 14, shallow recess 15, valve chamber 16 and duct 17. From the space within the annular seal 5, a communication exists with the interior of the flask 4 by way of an annular gap clearance present between the outer surface of dipper tube 10 and inner surface of neck 3.
  • valve 18 Positioned in the valve chamber 16 is a valve 18 having a head cngageable with the frustoconical valve seat formed in said chamber and having a stem 20 extending downwardly through the duct 17.
  • FIG, 3 which shows the sprayer head assembly of the invention in separate condition e.g. prior to being screwed on to a flask of liquid, it will be noted that valve 13 is seated by the action of spring 19, thereby cutting oit the gas owpath above described and thereby prevents the escape of gas out of the tank 6.
  • the dimensioning of the parts is so predetermined that as the sprayer assembly is screwed home over the neck 3 of the ask by way of the cooperating screw threads at 2a, the upper surface of the neck 3 of the flask forces the stem of valve 26 upwards against the action of spring 19, thereby completing the above mentioned gas flowpath and allowing the gas pressure from the reservoir 6 to act upon the free surface of the liquid in flask 4.
  • This condition of permanent gas pressure in the flask will be maintained so long as the sprayer assembly remains in its screwed-home condition, or so long as the gas pressure in the reservoir 6 has not been exhausted.
  • a sprayer assembly for attachment to a liquid container having a neck extending around a discharge opening, said sprayer assembly comprising a body having a recess with a side wall surface diametrically dimensioned to lit over the container neck for attaching said body to the container;
  • a pressure gas reservoir connected to said body
  • a clipper tube secured to said body centrally within said recess and projecting axially from the latter to extend into the container through the discharge opening of the latter upon reception of the container neck in said recess, said dipper tube having an outer diameter substantially smaller than the diametrical dimension of said recess so as to provide a radial clearance between said clipper tube and the container neck when the clipper tube extends through the discharge open- 111g;
  • said body having passage deiining means connecting said nozzle with said clipper tube;
  • Valve means interposed in said passage deiining means and controlling the ilow of iiuid through the latter;
  • additional passage defining meansl in said body extending from said reservoir and opening axially in said recess at an eccentric location spaced radially outward from said dipper tube and adjacent said side wall surface of the recess so as to communicate with the interior of the container through the discharge opening of the latter upon reception of the container neck in said recess, said additional passage defining means having a seat therein facing generally axially away from said recess;
  • additional valve means spring urged against said seat so as to normally seal said additional passage defining means and including a valve stem projecting axially from said opening of the additional passage defining means into said recess when said additional Valve means engages said seat and being engaged, and axially displaced by the container neck upon reception of the latter in said recess thereby to automatically unseat said additional valve means and permit the escape of gas from said reservoir into the container.
  • a sprayer assembly comprising a body having a generally cylindrical recess opening at the bottom thereof and receiving said neck to secure said assembly on said container, a pressure gas reservoir connected to said body, a dipper tube secured to said body centrally Within said recess and projecting axially from the latter through said opening into the container, said dipper tube having an outer diameter substantially smaller than the inner diameter of said neck to provide clearance therebetween, a spray outlet nozzle opening outwardly of said body, said body having first passage means connecting said nozzle with said dipper tube, first manually operable valve means interposed in said first passage means and controlling the flow of fluid through the latter, said body further having second passage means extending from said passage and terminating in an axial opening at the top of said recess which is spaced radially from the center of the latter by a distance lying between the inner and outer radii of said neck, said second passage means having a seat therein facing generally in 5 6 the axial direction away from said neck, second valve opening of the second passage means to prevent blocking means in said second passage means engageable
