  • the upper portion of the valve stem 32 extends above the outer and inner upper annular portions 50, 52.
  • the outer upper annular portion 50 and the inner upper annular portion 52 define a first adapter coupler (e.g., an upper adapter coupler) configured to removably secure the dispenser adapter component 22 to the container adapter component 20.
  • the dispenser system 14 generally includes a spray gun 60 (broadly, a spraying device), tubing 62 in fluid communication with the spray gun, a check valve 64 fluidly coupling the dispenser adapter component to the tubing, and may include the dispenser adapter component 22.
  • the spray gun 60 may include a nozzle 68, a handle 70, and an actuator 72 (e.g., a trigger).
  • the spray gun or spraying device may be of other designs or constructions. Operating the spray gun 60 dispenses the flowable product (e.g., aerosol).
  • the flowable product travels along a fluid path extending from the container 24 and through the valve assembly 26, the dispenser adapter component 22, the check valve 64, the tubing 62, and the spray gun 60.
  • the tubing 62 may be flexible tubing, and may be coiled, as illustrated.
  • the tubing 62 may include a coupling 78 threaded on or otherwise connected to an upper end of the check valve 64.
  • a lower end of the check valve 64 may be threaded on or otherwise connected to an upper portion of the dispenser adapter component 22, as shown.
  • the check valve 64 inhibits the flowable product from flowing back into the dispenser adapter component 22 and the container 24 to retain fluid in the flowable product in the fluid path.
  • the dispenser adapter component 22 generally includes an internal stem coupler 80 configured to fluidly and mechanically couple with the valve stem 32.
  • the stem coupler 80 defines a fluid passage that fluidly connects the stem 32 (and the valve assembly 26) with the check valve 64 and the remainder of the dispenser system 14, as seen in FIG. 8.
  • the illustrated stem coupler 80 has a lower portion that receives the stem 32 to couple the stem coupler to the stem.
  • the stem coupler 80 is disposed in an upper portion 84 of the dispenser adapter component 14.
  • the illustrated upper portion 84 is designed and constructed as a grip to be gripped by a user's hand (e.g., between thumb and one or more fingers).
  • the upper portion 84 has an elongate shape, similar to a rectangle or oval. Ribs 86 or other frictional features may be on the upper portion 84 to enhance grip.

  • the second adapter coupler includes a shroud 90 with an annular, depending flange that is configured to be received in the annular space between the outer and inner upper annular portions 50, 52 of the container adapter component 20. When the annular, depending flange is received in the annular space, the shroud 90 generally envelopes the inner upper annular portion 52.
  • the adapter components 20, 22 are couplable to one another by twist-locking.
  • at least one tongue 94 e.g., two or more tongues
  • two tongues 94 are diametrically opposite one another.

  • the stem coupler 80 is coupled to the vale stem 32 (e.g., the stem is received in the stem coupler) and rotation of the dispenser adapter component 22 relative to the container adapter component 20 (such as by gripping the grip and turning the upper adapter component in the clockwise or counterclockwise direction) engages the tongues 94 with undersides of sloped or descending ramps 100 or ribs extending radially inward from the upper outer annular portion 50, thereby imparting downward movement (i.e., translation) of the dispenser adapter component 22 relative to the container adapter component 20.
  • ramps 100 can be considered screw threads on which the tongues 94 ride against the biasing force of the valve spring 34 as the dispenser adapter component 22 is rotated. This axial translation of the dispenser adapter component 22, including the valve coupler 80, imparts downward movement of the valve stem 32 relative to the valve housing 30, thereby opening the valve assembly 26. Stops 102 at the ends of the ramps 100 are configured to engage the respective tongues 94 and inhibit further rotation of the dispenser adapter component 22. At this position, the dispenser adapter component 22 is locked onto the container adapter component 20 and the valve assembly 26 is open. In one embodiment, as can be seen from FIGS.
  • the dispenser adapter component 22 may be rotated about 45 degrees in the clockwise direction relative to the container adapter component 20 to lock the components to one another and open the valve assembly 26. Additional stops 106 adjacent the recesses 96 inhibit the dispenser adapter component 22 from rotating in the counterclockwise direction from the initial position.
  • the adapter 16, including the components 20, 22, thereof, may be formed from plastic or other suitable material, and may be formed by molding or in other suitable ways.
