Definitions
- the present invention is directed to a spinner assembly, for use with a discharge nozzle in a fluid dispenser such as a sprayer bottle, which may be assembled to the fluid discharge apparatus of the fluid dispenser from its exterior.
- the present invention is directed to a spinner assembly in which the spinner, priming valve, and compression spring positioned therebetween may be formed as a single piece, which may be assembled to the discharge nozzle from its exterior.
- the spinner assembly may form part of a discharge nozzle assembly which includes a cap adapted to fit over the spinner and variably engage the discharge nozzle.
- Fluid dispenser such as pump bottles, pump spray bottles, and in particular trigger sprayer bottles, are used to dispense a broad range of substances.
- Those substances include hand, face, and body lotions; and, cleaners for materials as diverse as wood, glass, vinyl, leather, suede, metals (such as aluminum, copper, brass, silver, and chrome), rubber (such as automobile tire brighteners), formica, ceramics, stainless steel, fabrics, painted surfaces, and the like.
- Trigger-type sprayer bottles While differing in specifics, generally share certain elements in common. Among these common elements are three referred to, for purposes of the present application, as the spinner, the priming valve, and the compression spring, which is located between the spinner and the priming valve. For purposes of convenience, these three elements are referred to collectively herein as the "spinner assembly".
- spinner assembly 60 must be placed within nozzle 56. This has at least two disadvantages compared with a spinner assembly which could be assembled to the fluid dispensing apparatus externally. First, the internal placement will require more time on the part of the assembler, slowing production time and increasing production costs. Second, should the spinner prove defective during quality control testing, the fluid dispensing apparatus must be disassembled in order to replace the defective spinner assembly.

- a foam-spraying apparatus wherein a liquid is first ejected from a hand dispensing pump through an atomizing nozzle, forming a spray, and the spray thus formed is then passed through foam-forming means.
- the foam-forming means includes a housing and a screen, and is operatively associated with the dispensing pump by a snap-fit mechanism (see, e.g., column 4, lines 42 et seq.).
- TADA U.S. Pat No. 4,350,298, is directed to an improvement in the nozzle cap of a foam dispenser, whereby the nozzle cap includes a plurality of arms forming an obstacle with which a liquid sprayed from an orifice of the foam dispenser collides. A plurality of foam outlet ports is provided between adjacent arms.
- the nozzle cap is moveable relative to the foam dispenser body between a sealing and a foaming position, and may be formed integrally with the foam dispenser nozzle through a hinge (see, e.g., column 3, lines 14 et seq., and claim 1).

- a rotatable nozzle cap having a plurality of longitudinal grooves which communicate with alternating radial and tangential channels. Rotation of the nozzle cap controls whether the fluid current passes along the longitudinal grooves and through the radial channels, producing a stream, or through the tangential channels, which impart a spin to the fluid current and produce a spray.
- Co-pending application U.S. Ser. No. 07/533,454, filed June 5, 1990, is directed to a fluid discharge apparatus for imparting a stream configuration to a current of fluid, in the form of a nozzle containing a passageway having at least a receiving portion with a substantially rectilinear cross-section, and an issuing portion with a substantially curvilinear cross-section.
- a fluid current passing through the passageway thereby emerges from it in a stream configuration.
- this apparatus may take the form of a cover or cap, hingedly connected to the discharge orifice region of the sprayer so that it can be reversibly attached to that orifice.
- selector mechanisms must cope with the fact that the initial fluid configuration which they are designed to change is generated by an internal mechanism, namely, the internally-mounted spinner assembly. Thus, at the point at which the selector mechanism acts to change the fluid configuration, the fluid has already passed beyond the spinner assembly and through the discharge orifice.
- Much of the prior art therefore provides a selector mechanism in the form of some type of cover or cap which may be reversibly attached to or placed over the discharge orifice.
- a spinner assembly which may be simply and efficiently assembled to a fluid dispensing apparatus from the exterior, and which may also cooperate directly with a selector mechanism, thereby simplifying production and use of the fluid dispenser while enhancing efficiency of operation and ease of use. It would also be desireable to provide a spinner assembly wherein the flow of pressurized liquid into the swirl chamber is controlled in a way which minimizes turbulence, thereby improving the characteristics of the output from the fluid dispensing apparatus and minimizing or even substantially eliminating dripping from the discharge orifice during use.
- a spinner Assembly adapted for external engagement with a discharge nozzle.
- the spinner assembly includes a priming valve configured to mate with a priming valve seat, biasing means for biasing the priming valve towards the priming valve seat, and a spinner head.
- the spinner head includes spinner means for imparting radial spin to a current of fluid passing through the spinner means, and sealing means for providing a fluid-tight seal between the spinner head and a nozzle cap configured to fit over the sealing means and engage the discharge nozzle.
- the spinner head may include an annular sealing flange, a post positioned within the annular sealing flange, and an annular chamber defined therebetween.
- the annular chamber may further include a fluid input end, having at least one aperture which communicates the annular chamber with the interior of the discharge nozzle.
- the annular chamber preferably has a larger cross-section than the at least one aperture, so that the velocity of a fluid projected along the interior of the discharge nozzle and through the at least one aperture will decrease when the fluid enters the annular chamber.
- the post includes at least one longitudinal groove, which begins at the top of the post and extends along at least a portion of its length. Preferably there will be a plurality of longitudinal grooves, evenly spaced around the circumference of the post. At least one of the longitudinal grooves and at least one of the apertures should be aligned on a common radius of the annular chamber.
- each of the longitudinal grooves is aligned with one of the apertures on a common radius of the annular chamber.
- there are two longitudinal grooves and four apertures with the two longitudinal grooves being spaced substantially at a 180° interval from each other around the circumference of the post and the four apertures being evenly spaced substantially at 90° intervals around the circumference of the post.
- the top of the post includes a swirl chamber surrounded by an annular wall.
- the annular wall has at least one tangential groove in it, communicating the swirl chamber with the annular chamber.
- the at least one tangential groove which may extend to substantially the full depth of the annular wall, should have substantially parallel sides, and its central axis should not intersect the axis of the swirl chamber. This results in fluid acquiring a radial spin as it passes through the tangential groove into the swirl chamber.
- the at least one longitudinal groove may communicate with the at least one tangential groove.
- this configuration includes four apertures, evenly spaced substantially at 90° intervals around the circumference of the post, with each of the longitudinal grooves being aligned with one of the apertures on a common radius of the annular chamber.
- the biasing means may be positioned between the priming valve and the spinner head, and the priming valve, biasing means, and spinner head may share a common longitudinal axis.
- the biasing means may be a spring, which includes at least one approximately sinusoidal wave form.
- the spring includes a plurality of approximately sinusoidal wave forms, in an alternating 180° configuration.
- the priming valve may further include centering means for centering the priming valve in the priming valve seat when the spinner assembly is engaged with the discharge nozzle.
- the priming valve may have a substantially continuously decreasing cross-section in the direction towards the priming valve seat, thereby effecting centering of the priming valve in the priming valve seat when the spinner assembly is engaged with the discharge nozzle.
- the priming valve may terminate in a longitudinal extension having a smaller cross-section than the priming valve seat. This longitudinal extension is configured to ensure proper alignment of the priming valve with the priming valve seat when the spinner assembly is engaged with the discharge nozzle.
- the present invention is also directed to a cap adapted to fit over the spinner assembly as defined above, and to variably engage the discharge nozzle.
- This cap may include a substantially annular side wall and a front face, with the front face having an outer side, an inner side, and an orifice.
- the inner side may include an annular central projection surrounding the orifice and having a height at least equal to the height of the annular wall. This annular central projection should be configured and positioned to sealingly engage the inside of the annular wall when the cap is substantially completely engaged with the discharge nozzle.
- the cap may be threadably engageable with the discharge nozzle such that rotation of the cap about its axis in a first direction brings the cap into increasing engagement with the discharge nozzle and moves the central projection towards the swirl chamber, while rotation of the cap about its axis in a second direction brings the cap into decreasing engagement with the discharge nozzle and moves the central projection away from the swirl chamber.
- the cap may be slidably engageable with the discharge nozzle, such that sliding of the cap along its axis in a first direction brings the cap into increasing engagement with the discharge nozzle and moves the central projection towards the swirl chamber, while sliding of the cap along its axis in a second direction brings the cap into decreasing engagement with the discharge nozzle and moves the central projection away from the swirl chamber.
- the inner face of the cap may include an annular outer projection surrounding and spaced from the central projection. Between the central projection and the outer projection there is defined an annular groove, having a width substantially identical to the width of the annular wall. In this manner the annular wall may be sealingly engaged between the central projection and the outer projection when the cap is substantially completely engaged with the discharge nozzle.
- the outer projection should have a height sufficient to extend at least to the bottom of the tangential groove when the cap is substantially completely engaged with the discharge nozzle.
- the surface of the inner side of the cap is preferably substantially smooth and, except for the central projection and, where present, the outer projection, substantially flat.
- the present invention is directed to a spinner and discharge nozzle assembly in a trigger sprayer for dispensing a liquid.
- the spinner and discharge nozzle assembly include a nozzle assembly having a liquid nozzle chamber therein, and a spinner assembly having a spinner head in sealing engagement with the nozzle assembly at a downstream end thereof.
- the spinner head may further include a base portion, a central post extending downstream from the base portion, and an annular flange extending downstream from the base portion.
- the annular flange surrounds the base post and is spaced outwardly therefrom, such that an annular liquid chamber is defined therebetween.
- the base has aperture means therethrough communicating the nozzle chamber with the annular chamber, and the annular chamber imparts a reduction in velocity of the liquid when the liquid enters the annular chamber from the aperture means.
- a swirl chamber is located at the downstream end of the post, which has an annular wall defining a swirl chamber therein and passage means communicating the annular chamber with the swirl chamber.
- the passage means may include at least one tangential groove, and at least one longitudinal groove, in the wall of the post.
- the longitudinal groove opens toward and is located within the annular chamber, and communicates with the tangential groove.
- the longitudinal groove and the tangential groove may be aligned along a common radius of the spinner head.
- the present invention also includes, in combination with this assembly, a cap adapted to fit over the spinner head and variably engage the discharge nozzle between open and closed positions.
- the cap includes a substantially annular side wall and a front face, with the front face having an outer side, an inner side, and an orifice.
- the inner side has an annular groove surrounding the orifice for receiving the annular wall at the downstream end of the spinner post. Sealing means may be provided for establishing a liquid-tight seal between the annular flange of the spinner head and the annular side wall of the cap.
- the fit between the inner circumferential surface of the inner wall and the inner circumferential surface of the annular groove provides a liquid sealing engagement therebetween, preventing liquid from flowing between the engaging surfaces of the annular wall and the annular groove.
- the width of the annular groove and the width of the annular wall are substantially equal, to provide liquid sealing engagement both between the inner circumferential surface of the annular wall and the inner circumferential surface of the annular groove, and between the outer circumferential surface of the annular wall and the outer circumferential surface of the annular groove. In this manner, the flow of liquid between the engaging surface of the annular wall and the annular groove is prevented.
- the outer circumferential surface of the annular groove extends at least to the bottom of the tangential groove, and the longitudinal groove extends from the tangential groove past the outer circumferential surface of the annular groove. It is also preferred that the tangential groove extend to substantially the full depth of the annular wall.
- the cap may have a central projection that seals against the floor of the swirl chamber with the cap in its closed position, to block the flow of liquid through the orifice.
- the spinner and discharge nozzle assembly may further include a priming valve configured to mate with a priming valve seat, and a spring extending between the base of the spinner head and the priming valve.
- the spinner head, spring, and priming valve are preferably of integral, one-piece, molded plastic construction.
- FIG. 1 depicts the cap, spinner, and discharge nozzle assembly according to the present invention.
- the cap In the position shown, the cap is fully engaged with the discharge nozzle, such that the annular groove 52 defined by central projection 51 and outer projection 53 on the inner face of the cap is sealingly engaged with the annular wall 45 surrounding the swirl chamber 44.
- FIG. 2 is a partial view showing the cap backed off from the discharge nozzle to such an extent that there is no overlap between the annular groove 52 and the annular wall 45 of the swirl chamber 44. In this position, the assembly will produce a stream.
- FIG. 3 is another partial view showing a position intermediate to that of FIG. 1 and FIG. 2.
- the cap is backed off sufficiently to allow fluid to flow through the resulting apertures 60 in the tangential grooves in the annular wall and into the swirl chamber, but the annular groove is overlapping the annular wall such that fluid cannot enter the swirl chamber other than through the tangential grooves. In this position, the assembly will produce a spray.
- FIG. 4 is a top plan view of the swirl chamber 44, showing one configuration of the tangential groove 46 in the annular wall 45.
- FIG. 5 is identical to FIG. 1, except that the inner side of the front face of the cap is shown having only central projection 51 engaging annular wall 45, without the outer projection (the remaining reference numerals have been omitted for clarity).
- a one-piece spinner assembly which can be assembled to a fluid dispensing apparatus from the exterior. Moreover, due to the placement and configuration of the spinner portion of the spinner assembly, the spinner can cooperate simply and efficiently with a selector mechanism for controlling both the flow and shape of fluid projected from the fluid dispenser.
- fluid dispensing apparatus refers to the apparatus or mechanism used to draw up a fluid from a fluid container and expel it in a desired direction and/or configuration.
- the fluid dispensing apparatus would be the trigger sprayer assembly.
- the fluid dispensing apparatus would be the pump mechanism.
- fluid container refers to the container used to store fluid as a reservoir to be drawn upon by the fluid dispensing apparatus.
- this will simply be a bottle, which may be, for example, glass or plastic, and which may assume a wide range of shapes, sizes, colors, and configurations without departing from the scope of the present invention.
- fluid dispenser describes the complete assembly of housing, fluid dispensing apparatus, and fluid container. In other words, the fluid dispenser is what the end user would pick up and use to dispense fluid.
- stream configuration means a substantially coherent, cylindrical column of fluid, and is to be distinguished from a spray configuration, in which a fluid is dispersed in an expanding conical pattern.
- a spinner assembly consists of the spinner, the priming valve, and the compression spring which connects the spinner and the priming valve. Each portion of the spinner assembly has a particular function.
- the compression spring urges the priming valve into a valve seat through which the fluid must move in its passage towards the discharge orifice.
- this is necessary to enable the fluid dispensing apparatus to ⁇ prime ⁇ , that is, to permit the fluid to be drawn up from the fluid container on the return stroke of the trigger or pump mechanism.
- the sealing of the valve seat by the priming valve prevents fluid from leaking out of the discharge orifice.
- the spinner shapes the fluid into a desired configuration, such as spray or stream, before it passes through the discharge orifice.
- a desired configuration such as spray or stream
- One common form of spinner involves a central, cylindrical chamber, having two or more inlet ports which are shaped and/or positioned to impart a spin to the fluid passing through them into the central chamber.
- the trigger sprayer includes a nozzle, a spinner assembly, and a cap.
- the nozzle has a nozzle fluid chamber 10 and a valve seat 12 at the rear end.
- the spinner assembly has a spinner head 14, a spring 16, and a priming valve 18 that seats within the valve seat 12. It also includes a centering guide 20 and a centering probe 22.
- the spinner assembly is of one-piece construction.
- the spinner head 14 is essentially a solid core with an annular chamber 32 formed in the top or forward end of the head.
- the annular chamber 32 defines an outer annular sealing flange 34 that provides a fluid-tight seal at 36 with an interior surface of the cap, and also defines a central post 38.
- the spring 16 extends from the bottom or rearward end of the head.
- Apertures 40 extend through the base of the annular chamber and communicate the nozzle chamber with the annular chamber 32.
- the apertures 40 are located just outwardly of the post 38, adjacent its periphery.
- Longitudinal grooves 42 extend along opposite sides of the post 38. The grooves are generally U-shaped in cross-section and open toward the annular chamber 32.
- a swirl chamber 44 is located in the top or front of the post 38 within annular wall 45.
- Tangential grooves 46 are located in the annular wall 45 and extend between the longitudinal grooves 42 and swirl chamber 44. The tangential grooves preferably extend the full depth of the annular wall 45.
- the cap threadingly engages the nozzle and has an orifice 50 in its front face.
- central projection 51 is surrounded by an outer projection 53, defining therebetween an annular groove 52 having an inner circumferential surface 54 and an outer circumferential surface 56.
- the inner side 58 of the front face of the cap is smooth and extends from the bottom of the outer circumferential surface 56 to the annular side wall of the cap such that the inner surface 58 defines a generally smooth flat disk. This smoothness helps minimize turbulence in the fluid entering the annular chamber which, as will be explained in greater detail below, improves the characteristics of the sprayer produced by the spinner assembly.
- the annular wall 45 of the post 38, and the annular groove 52 are dimensioned to provide a snug, or essentially zero clearance, fit between the inner surface of the annular wall 45 and the inner circumferential surface 54 of the cap, and also between the outer surface of the annular wall 45 and the outer circumferential surface 56, so that virtually no fluid is allowed to pass between these surfaces.
- the length of the inner circumferential surface 54 is somewhat greater than the depth of the annular wall 45 so that the rear of the circumferential surface 54 can contact the bottom of the swirl chamber 44 with the cap screwed in to its closed position to seal off the orifice 50.
- the outer circumferential surface 56 preferably should be at least as long as the inner circumferential surface 54, and preferably somewhat longer so that it extends at least to the bottom of the tangential grooves 46.
- the longitudinal grooves 42 extend from the bottom on the tangential grooves 46 rearwardly to a location past the outer circumferential surface 56, so that fluid in the chamber 32 is always allowed to pass into the tangential grooves 46 without significant restriction even with the cap closed.
- the longitudinal grooves 42 may extend rearwardly all the way back to the forward end of the apertures 40.
- liquid from the nozzle chamber 10 flows forwardly through the apertures 40 in the spinner head and into the enlarged annular chamber 32, with a resulting drop in velocity.
- the liquid in the chamber 32 enters the longitudinal grooves 42 and from there flows into the tangential grooves 46.
- the cap With the cap in the closed position, the liquid is blocked from passage into the orifice 50 because of the contact of the rearward end of the inner circumferential surface 54 with the bottom of the swirl chamber 44, and because of the sealing engagement between the inner circumferential surface 54 and the inner surface of the annular wall 45 as provided by the snug fit between those surfaces.
