  • the housing 30 functions as the trigger for the spray actuator 10, and also serves as the support structure for the spray nozzle 40.
  • a slidable locking mechanism 50, 51 is provided through the base 20 for selectively locking the housing 30 against rotation on the base 20.
  • the locking button 51 of the locking mechanism is depressed and the unlocking button 50 is extended, thereby holding the housing 30 in a locked position in relation to the base 20.
  • the base 20 includes a contoured hand-engaging portion 22 which provides an ergonomic design, as more fully described below.
  • Interchangeable spray nozzles 40, 140 and 240 may be removably installed in the front opening 31 of the housing 30 in order to provide varying spray patterns.
  • paint spray patterns may be varied depending upon the particular spray nozzle chosen.
  • different spray nozzles 40, 140 and 240 may be used to form spray patterns that are generally square, flat, round and the like.
  • the spray nozzle 40 shown in Figs. 1-5 may produce a generally square spray pattern
  • the spray nozzle 140 shown in Fig. 6 may produce a generally flat spray pattern
  • the spray nozzle 240 shown in Fig. 7 may produce a generally round spray pattern.
  • the nozzle housing 30 may be provided as an integral component that includes a front trigger surface 32 below the spray nozzle 40 at the front of the housing 30, and a top trigger surface 33 at the top of the housing 30 above the spray nozzle 40.
  • the user may elect to use either or both of the front trigger surface 32 and/or the top trigger surface 33 during spraying operations.
  • a user may choose to depress the front trigger surface 32 with a finger, or to depress the top trigger surface 33 with a finger or thumb.
  • the top upper trigger surface 33 may be depressed by the user's other hand.
  • the spray nozzles 40, 140 and 240 are mounted in the housing 30 of the actuator 10 at a spray discharge angle A that is not perpendicular to the longitudinal axis of the aerosol container 5, and is not parallel with a plane defined by the bottom rim of the actuator base 20.
  • the spray discharge angle A may be measured from a line L that is perpendicular to the longitudinal axis base 20 of the aerosol container 5 when the actuator 10 is in its closed or neutral position.
  • the spray discharge angle A may also be measured in relation to a plane P defined by the lower rim of the actuator base 20.
  • the spray discharge angle A may typically range from 5-50°, for example, from 10-45°, or from 12-40°, or from 15-30°, or from 18-25°. In a particular non-limiting example, the discharge spray angle may be about 20 or 21°.
  • Spray discharge angles are also illustrated in Figs. 11 and 12.
  • the actuator is in a closed or neutral position, and the spray discharge angle A corresponds to that shown in Fig. 9.
  • Fig. 12 illustrates that the spray discharge angle A' may be decreased from the spray discharge angle A shown in Figs. 9 and 11 when the actuator 10 is in its fully open or actuated position.
  • the decreased spray discharge angle A' may result from rotational movement of the housing 30 during spraying operations.
  • the actuated spray discharge angle A' may be from 0-12° less than the neutral spray discharge angle, or from 1 -10° less, or from 3-8° less.
  • Figs. 14 and 15 illustrate a spray actuator 10 with the spray nozzle removed.
  • the circular front opening 31 is provided in the housing 30 with internal threads extending inward from the front surface of the housing 30.
  • a paint delivery port 37 is located at the center of the threaded housing opening 34.
  • the housing includes a nozzle stem 34 including a tubular section 35 with a central fluid delivery line 36 and a lower inlet opening 37 that contacts the stem 8 of the container 5.
  • An upper outlet opening 38 is provided at the outlet end of the fluid delivery line 36.
  • a selected spray nozzle 140 may be installed in the opening 31 of the housing 30 by threading the spray nozzle 140 into the threaded housing opening 31.
  • a delivery line 45 for paint or other material extends centrally through the spray nozzle 140, and is in flow communication with the delivery port 37 and delivery line 36 of the nozzle stem 34.
  • the housing 30 may rotate in a direction R around a pivot pin 24 from the closed position shown in Fig. 17 to an open position in which the nozzle stem 34 presses against and depresses the stem 8 of the aerosol container 5.
  • Such rotational movement R allows paint or other material contained within the spray container 5 to exit through the delivery line 36 and port 37 of the nozzle stem 34 into the delivery line 45 of the spray nozzle 140 for discharge from the nozzle.
  • the rotation R may be caused by pressing the housing 30 at locations such as the front trigger surface 32 and/or top trigger surface 33.
  • the trigger housing 30 may be biased against rotation by the valve stem 8 of the aerosol container, as more fully described below and shown in Fig. 18.
  • the trigger housing 30 may be biased against rotation by any other suitable means known to those skilled in the art, such as a spring, resilient compressible material, living hinge, or the like.
  • the locking mechanism 50, 51 is used to allow or prevent the rotation R.
  • Fig. 18 illustrates a conventional aerosol container stem 8 and stem biasing mechanism 9, which may be used to bias the trigger housing 30 toward its closed or neutral position.
  • the spring-loaded biasing mechanism 9 resists the rotation R such that a desired amount of pressure must be applied by the user to the front and/or top trigger surfaces 32 and 33 during spraying operations.
  • the spring-loaded stem biasing mechanism 9 also exerts sufficient force to the aerosol container stem 8 and the delivery port 37 of the nozzle stem 34 in order to return the housing 30 to its closed neutral position after spraying operations.
  • the spray nozzle 40 includes a central spray discharge opening 41 and a generally cross-shaped depression that creates a generally square spray pattern.
  • Opposing finger tabs 43 extend from the front of the spray nozzle 40 to allow the user to twist the threads 46 of the nozzle 40 into and out of the front opening 31 of the housing 30.
  • the spray nozzle 140 shown in Figs. 27-30 has many of the same features as the spray nozzle 40 shown in Figs. 19-22, except a generally linear depression 142 is provided that creates a flat spray pattern.
  • the spray nozzle 240 shown in Figs. 24-27 also has many of the same features as the spray nozzle 40 shown in Figs. 19-22, except a generally circular conical depression 242 is provided that creates a round spray pattern.
  • Figs. 31 and 32 are exploded views of the container 5 and spray actuator 10, illustrating the various component parts thereof.
  • Fig. 33 illustrates different types of spray patterns achievable with different types of spray nozzles 40, 140 and 240 in accordance with embodiments of the present invention.
  • the spray nozzle 40 produces a generally square spray pattern 48; the spray nozzle 140 produces a generally flat spray pattern 148; and the spray nozzle 240 produces a generally circular pattern 248.
  • the aerosol container 5 may be held in a non-vertical orientation that results in a generally horizontal discharge direction, which may be desired for many types of spraying operations including spray painting.
  • the spray discharge angle A of the nozzles 40, 140 and 240 thus provides an ergonomically favorable angled orientation for the aerosol container in which the operator's hand is in an extended position, as shown in Fig. 34, rather than bent back at a significant angle, e.g., as shown for conventional aerosol paint spray actuators in Figs. 35 and 36.
  • the contoured hand-engaging portion 22 that extends around the sides and back of the spray actuator base 20 to provide a cradle surface that generally conforms with the shape of the thumb and index finger region of a typical user's hand.
  • the front trigger 32 under the spray nozzle 40 has a relatively large surface area for comfortable engagement with at least one finger of the operator, and the top trigger surface 33 has a relatively large surface area for comfortable engagement with the operator's finger(s), thumb and/or other hand.
  • the spray discharge angle A, contoured hand cradle 22, and enlarged front and top trigger surfaces 32 and 33 all contribute to an improved ergonomic design that is comfortable to use.
  • any numerical range recited herein is intended to include all sub-ranges subsumed therein.
  • a range of "1 to 10" is intended to include all sub-ranges between (and including) the recited minimum value of 1 and the recited maximum value of 10, that is, having a minimum value equal to or greater than 1 and a maximum value of equal to or less than 10.
