Definitions

  • the present invention relates generally to trigger actuated sprayers for dispensing liquid from- a"container, particularly to the trigger assembly for such a sprayer, and to methods for assembling a complete device.
  • Trigger actuated sprayers which dispense liquids in response to depression of a trigger are well known.
  • the sprayers have received wide consumer acceptance and appea due to the ease of handling the sprayer, the efficiency with which the sprayer dispenses liquid, and the convenience of using such a sprayer.
  • the sprayers are used to dispense a variety of liquid products, such as cleaning solutions, cosmetics, toiletries, agricultural and industrial products.
  • Such trigger sprayers have a nozzle for dispensing either a spray or a stream of the liquid products.
  • the aim point of the nozzle must be kept relatively constant as the trigger handle is depressed.
  • three alternatives are available to ensure that the aim point does not substantially change. The alternatives are illustrated schematically in Figs. 1, 2 and 3.
  • nozzle 101 may be fixed onto the trigger sprayer body so that it does not move as trigger handle 102 is operated.
  • the trigger handle in a device using this alternative compresses a separate pump 103 in the direction of the arrow.
  • An unshown passage communieating with the nozzle leads the liquid from the pump to the nozzle.
  • U.S. ' Patent 3,061,202 to Tyler illustrates a trigger sprayer using a fixed nozzle and a separate pump.
  • nozzle 101 is formed integrally with pump 103.
  • the nozzle is formed so that the aim point coincides with the pumping axis of the pump.
  • trigger handle 102 is depressed to operat the pump, the nozzle moves back along the pumping axis, i the direction of the arrow, thereby maintaining a constan aim point.
  • U.S. Patent 3,701,478 to Tada illustrates a trigger sprayer in which the nozzle moves back along the pumping axis as the trigger handle is depressed.
  • the third alternative to keep the aim point of the nozzl relatively constant is to mount the nozzle at the end of the pump and to aim the nozzle at an angle relative to t pumping axis.
  • nozzle 101 is mounted at a right angle relative to pump 103.
  • trigger handle 102 is operated, the pump is depressed and the nozzle moves down in the direction of the arrow with the pump.
  • the aim point of the nozzle in this alternative moves slightly in the vertical direction, for all practical purposes the aim point is constant.
  • U.S. Patent 4,077,549 to Beard illustrates a trigger sprayer in which the nozzle descends as the trigger handle is depressed.
  • the radial distance between the pivot point for the handle 106 and the depression point of the handle changes. This is shown schematically in Fig. 4a.
  • the radial distance LI between the pivot point P of the trigger handle and the depression point D of the trigger handle is different than the radial distance when the trigger handle is released.
  • the released position is indicated by the dotted lines in Fig. 4a.
  • the released distance L2 is considerably less than the depressed distance LI.
  • the usual structure consists of a cam and a sliding surface which allows the trigger handle ro pivot about its pivot point while maintaining the nozzle (or the pump in the Fig. 1 alternative) in its desired orientation.
  • a cam and a sliding surface are denoted by numerals 105 and 104, respectively, in Figs. 1, 2 and 3.
  • a cam and a sliding surface may be seen in Fig. 3, reference numerals 40 and 41 in Tyler; Fig. 2, reference numerals 54 and 55 in Tada; and Fig. 1, reference numerals 17 and 26 in Beard.
  • the present invention is a trigger sprayer designed to overcome the above mentioned disadvantages of conventiona trigger sprayers.
  • the present invention is a trigger sprayer incorporating a special "living" hinge as the pivot point for the trigger handle.
  • the "living" hinge comprises a flexure which may be distorted in response to depression of the trigger handle.
  • the distortion is both an angular distortion to allow the trigger handle to rotate about the pivot point as the trigger handle is depressed, and a lateral distortion to accommodate the change in radial distance between the pivot point and. the depression point (compare Fig. 4a with Fig. 4b).
  • This flexure provides a moving hinge point for the trigger handle.
  • the flexure can be integrally molded with the frame and. the trigger handle, thus reducing the number of parts required to construct a trigger sprayer. Accordingly, th complexity and tolerances which must be maintained are significantly reduced, and the device may be constructed with ease.
  • the present invention addresses the problem of leakage from the trigger sprayer by positioning the pump assembly of the sprayer completely within the container for the liquid.
  • the pump also incorporates a lip structure which in terms of a preferred embodiment of the invention, is located at the upper surface of the piston of the pump. This lip dovetails with a complementarily shaped structur in an upper surface of the pump, to form a seal effective to reduce significantly the amount of liquid which leaks from the trigger sprayer when the sprayer is unused or is in an inverted position.
  • Assembly of the finished product is facilitated by the modular structure of the trigger sprayer.
  • the pump and the trigger sprayer may be separately assembled, and even assembled a different locations.
  • the structure of the sprayer reduces the number of parts with critical tolerances and provides for easy interconnection of the disjoint modules. Accordingly, assembly of a finished product may be accomplished by inserting a pump module into a filled container, and snapping a trigger sprayer module over the pump module.
  • the structure of the trigge sprayer quickly accommodates mating connections on the pump module, and the mount on the trigger sprayer module seals both the trigger sprayer module and the pump modul to the filled container with a simple thrusting motion, i.e. no rotational motion is required.
  • Figs. 1, 2 and 3 are schematic representations of conventional trigger sprayers,-
  • Fig. 4a is a diagram illustrating the change in radial distance between the pivot point and the depression poin as the trigger handle of a conventional trigger sprayer is depressed
  • Fig. 4b is a diagram illustrating flexure distortion of the present invention .
  • Fig. 5 is an exploded perspective view of an embodiment o the present invention .
  • Fig. 6 is a cross-sectional view of the assembled embodiment shown in Fig.5;
  • Fig. 7 is cross-sectional view of the nozzle assembly for the embodiment shown in Fig. 5;
  • Fig. 8 is a perspective view of a ball valve usable with the invention ;
  • Figs. 9A and 9B are cross-sectional and plan views, respectively, of a mounting which facilitates assembly of the device ;
  • Fig. 10 is a schematic representation- of- an alternate embodiment of the present invention.
  • the device is a modular trigger sprayer having an integrally molded flexure or "living" hinge.
  • the device has a generally U-shaped frame 1.
  • Strengthening rib 2 is formed at the base of the frame to provide additional rigidity for the structure as the device is operated.
  • Lower leg 4 of the frame merges with cap 5 having bayone connector 6 for attachment to a bottle or a container (no shown) .
  • a screw connector or a snap-on connector may als be used.
  • Upper leg 7 of the frame merges into a dependent trigger handle 9.
  • the handle is angled relative to this leg, and extends in the general direction of cap 5.
  • the flexure is formed at the base of upper leg 7. As best seen in Fig. 6, the flexure has an arcuate shape which allows it to distort freely both angularly and laterally. The angular distortion allows the trigger handle to rotate about its pivot point, while the lateral distortion allows the upper leg to be displaced laterally by means to be described later.
  • the flexure is molded from polypropylene, but any material having sufficient flexibility and strength, such as nylon, may be used.
  • the flexure may be formed from a strip of metal which connects an upper leg molded separately from the remaining frame. Use of a metallic strip having a high spring constant also permits elimination of internal biasing springs within the trigger sprayer, and may be preferred when the trigger sprayer is used to dispense corrosive products.
  • the materials also provide a return force to return the trigger sprayer to its quiescent state after the trigger handle has been depressed and released.
  • the flexibility, distortability and plastic memory are all functions of the material used and the dimensions of the flexure.
  • the flexure is approximately 0.4 inches (10mm) wide by 0.1 inches (2.5mm) thick by 0.3 inches (7.5ram) long (measured along the arc of the flexure) .
  • th thickness is preferably in the range of 0.05 and 0.20 inches (1.25 ⁇ m-5rrm outside this range', the flexure is either too fragile, or the trigger sprayer is too hard to operate.
  • the length should be in the range G.10 to 0.50 inches (2.5 ⁇ m-12.5r ⁇ m) the same reasons.
  • the width of the flexure should be sufficient fully to accommodate delivery arm 22, to be described later.
  • Upper leg 7 also includes channel 11, the third side of which channel is formed by side member 12.
  • Side member 1 is attached to the upper leg of the frame by press fit of pins 13 and 14 within holes 15 and 16, respectively. (Se Fig. 6.)
  • Side member 12 also includes a frangible locking lever 17, which is rotatable about an axis formed by the lower edge of the side member.
  • the locking lever may be press-engaged around neck 19 of cap 5 to prevent undesire actuation of the device. If desired, the locking lever can be designed solely to prevent actuation during shipment, and can be completely removed prior to use.
  • Pawl 20 is also mounted on side member 12 and engages projection 21 to limit the extent of upward travel of upper leg 7. The engagement of pawl 20 with projection 21 also serves to prevent damage to the sprayer if it is lifted by trigger handle 9.
  • Delivery arm 22 is mounted for rotational movement within channel 11 by mutual engagement of pivot pin 24 with pivot hole 25 in the upper leg of the frame and mutual engagement of an unshown pivot pin with pivot hole 26 in side member 12.
  • the pivot points allow delivery arm 22 to rotate with respect to the channel. It should be understood that although pivot points are depicted, a segment of flexible material (plastic, for example) may b utilized to attach delivery arm 22 to upper leg 7 and to provide for rotational movement within channel 11.
  • delivery arm 22 is substantially hollow with a rectangular cross section.
  • Nozzle 26 is inserted at a distal end of the delivery arm.
  • nozzle 26 has a small hole 27 for expelling liquid in a stream or spray.
  • a swirl chamber comprising channels 29 is formed.
  • Swirl plug 30, also enclosed within the delivery arm, is inserted into nozzle 26.
  • the swirl plug channels liquid moving through the delivery arm to the extreme portions of the swirl chamber, to impart angular momentum to the liquid flow. This conditions the flow of liquid prior to being expelled through the hole in the nozzle to allow a more uniform and more precise spray or stream to be formed.
  • the swirl plug or the nozzle may be made movable to vary the characteristics o the spray or stream, or completely to- seal the nozzle.
  • Swirl plug 30 extends leftwardly as shown in Figure 6 ' an widens into insert post 31.
  • the interior of insert post 31 is sealed with locking plug 31a to prevent formation an air cushion which would adversely affect operation of the sprayer.
  • tubular extension 32 is formed perpendicularly relative to the delivery arm, to accept tubular extension 32.
  • the lower end of tubular extension 32 is flared into an inverted cup-shape to form piston 34 for a pump.
  • lip 35 is formed in the piston.
  • Tubular extension 32 is inserted through a hole in ferrul 36 which has a complementarily shaped lip 37 formed on th inside thereof.
  • tubular extension 32 is also inserted through an opening 40 in cap 5 and press-fit into the depending tubular section of the delivery arm.
  • ball 41 is supported within the upper portion of the tubular extension by a series ,of ribs 42.
  • the bal is urged' downwardly by spring 44, which is confined withi the tubular extension by cylindrical insert 45.
  • the spring biases the ball against an aperture in seat 46 formed by the series of ribs, to form a valve within the tubular extension.
  • Figure 8 show a plastic ball insert molded from a single piece of plastic and designed to be press fit into tubular extension 32.
  • the insert includes a washer-shaped upper plate 61 for engagement with the inner surface of the tubular extension.
  • Two plastic helixes 62 extend downwardly from the plate and terminate in a plastic hemisphere 64 having the same diameter as ball 41.
  • the helixes act as a spring and permit hemisphere 64 to move upwardly against a spring bias.
  • Cylinder 47 of pump 49 is flared at the upper end 48 for tight engagement with the sides of a recess formed in the inside top surface of cap 5, so that the cylinder and the cap are effectively fixed one to the other.
  • the inner diameter of the cylinder is constructed to seat ferrule 36 tightly.
  • the lower end of cylinder 47 tapers gradually to nipple 50 which is adapted frictionally to receive dip tube 51.
  • the interior of the cylinder closely accepts piston 34.
  • the lower end of the interior of the cylinder is formed with a recess consisting of confining ribs 52 which loosely confine ball 54. These ribs also serve as a seat for compression spring 55 which extends upwardly to the inner surface of piston 34, thus urging the piston in a direction away from the dip tube and causing the lip of the piston to seal with the lip of the ferrule.
  • tubular extension32 may loosely fit into the hole in ferrule 36. This wide latitude in dimensional accuracy contributes to the low cost and simple manufacture of the sprayer.
  • the radial distance between the flexure 10 and the pivot point 25-26 of the delivery arm would normally be greater than the radial distance when the trigger handle is in the free position, as shown schematically in Fig. 4a.
  • the flexure must distort laterally as it rotates angularly. This is shown schematically in Fig. 4b.
  • the flexure has distorted laterally from PI to P2. This allows the radial distance L to remain constant during depression of the trigger handle, and eliminates the need for the complicated structures conventionally found to accommodate a change in radial distance (Fig. 4a) .
  • the shape of the flexure, its location and construction allow the lateral and angular distortion to take place freely.
  • the tubular extension 32 also moves downwardly lowering the piston 34 in the cylinder 47 against the action of compression spring 55. Air is expelled through the upper ball check 41.
  • the compression spring bearing against the inner seat in the cylinder formed by ribs 52, drives the piston, the piston rod, the delivery arm, the upper frame leg and the trigger handle back to their respective initial positions.
  • Ball 54 prevents the return of the fluid to the container, although a flapper valve may be utilized in place of this - 14 - -
  • a further cycle of the trigger forces the fluid up through the tubular extension, past the upper ball, along the delivery passage way and to the atmosphere through the nozzle and swirl chamber.
  • the upper ball prevents the flow of fluid back to the- cylinder. Repeated operations produce repeated intermittent discharge of liquid through the nozzle.
  • Venting of the container takes place from the atmosphere.
  • air from the atmosphere seeps through the clearance between tubular extension 32 and the aperture 40 in cap 5, and occupies the space behind the piston within the cylinder.
  • opposed vent ports 56 Fig. 6
  • This air replaces the volume of fluid drawn into the pump, and prevents the container from collapsing.
  • Figures 9A and 9B illustrate a mounting arrangement for the trigger sprayer which has been found to be particularly effective.
  • the figures illustrate cap 70 which is much the same as cap 5 shown in Figure 5.
  • Neck 71 of a container is in close proximity to the cap.
  • the cap includes a pair of diametrically opposed openings 72 below each of which is formed stub 74.
  • the lateral ends of the stubs may be cut away as shown at 73 in Figure 9B; although this is not absolutely necessary it permits the stubs to displace more easily.
  • each stub has a ramp 75 designed to interact with a similar ramp 77 on projection 76 on the container.
  • Container 71 also includes a pair of * restraining ribs 79 which, by restraining stub 74, prevent rotation of the cap when assembled on the container.
  • a pump module 49 (Fig. 5) including tubular extension 32, ferrule 36, gasket 39, and dip tube 51 is inserted into the mouth of the container, which has previously been filled with product.
  • the mouth of the container is then aligned with the cap of the trigger module (including U-shaped frame 1, handle 9, delivery arm 22 with nozzle and swirl plug, and side plate 12) so that the stubs of the cap are aligned with ribs 79.
  • the cap and container are then laterally advanced relative to each other until ramps 77 and 75 mutually engage.
  • the ramps may be on the cap or on the container, or one ramp may be formed on each the cap and the container to limit assembly to a particular orientation. Also, one of the ribs in the pair of ribs 79 may be omitted to permit a consumer to rotate and remove the cap to refill the container.
  • the relative orientation between the tubular extension and the delivery arm should not be limited to right angles as shown in the preferred embodiment; indee any orientation and direction of spray is contemplated.
  • the relative arrangement of the piston within the cylinder of the pump may be reversed, so that the trigger handle operates the pump by drawing the piston u from the cylinder rather than depressing a piston into t cylinder.

Abstract

Un vaporisateur actionné par une gâchette distribuant des produits liquides, comprend un point d'articulation mobile pour le manche (9) du vaporisateur se présentant sous la forme d'une flexion (10). Ladite flexion (10) permet une orientation constante de l'ajutage de vaporisation (26) à maintenir en accomodant les changements de distance radiale à mesure que l'on presse sur la poignée de détente (9), tout en réduisant la complexité et le nombre de pièces de la structure globale. On a placé un élément étanchéifiant (36) dans le piston (34) et le cylindre (47) de la pompe (49) afin que ledit dispositif réduise les fuites du produit liquide lorsque la pompe ne sert pas ou est inversée.,
