43  US 6,503,413 B2  44  Air aspirated sprayers include the classification of spray› ers generically known as "air brushes". A stream of pres› surized air draws up the aqueous wrinkle control composi› tion and dispenses it through a nozzle to create a spray of  liquid. The wrinkle control composition can be supplied via  separate piping/tubing or more commonly is contained in a  jar to which the aspirating sprayer is attached.  A broad array of trigger sprayers or finger pump sprayers  are suitable for use with the compositions of this invention.  These are readily available from suppliers such as Calmar,  Inc., City of Industry, California; CSI (Continental Sprayers,  Inc.), St. Peters, Mo.; Berry Plastics Corp., Evansville, Ind., 65  a distributor of Guala sprayers; or Seaquest Dispensing,  Cary, Ill.  A more complete disclosure of commercially available  dispensing devices appears in U.S. Pat. No. 4,082,223,  Nozawa, issued Apr. 4, 1978; U.S. Pat. No. 4,161,288,  McKinney, issued Jul. 17, 1985; U.S. Pat. No. 4,434,917,  Saito et al., issued Mar. 6, 1984; and U.S. Pat. No. 4,819,  835, Tasaki, issued Apr. 11, 1989; U.S. Pat. No. 5,303,867,  Peterson, issued Apr. 19, 1994; all of said references are  incorporated herein by reference.  Nonlimiting examples of commercially available pow› ered sprayers are disclosed in U.S. Pat. No. 4,865,255,  Luvisotto, issued Sep. 12, 1989 which is incorporated herein  by reference. Preferred powered sprayers are readily avail- able from suppliers such as Solo, Newport News, Va. (e.g.,  Solo Spraystar™ rechargeable sprayer, listed as manual  part #: US 460 395) and Multi-sprayer Systems,  Minneapolis, Minn. (e.g., model: Spray 1).  Powered sprayers include self contained powered pumps  that pressurize the aqueous de-wrinkle composition and  dispense it through a nozzle to produce a spray of liquid  droplets. Powered sprayers are attached directly or remotely  through the use of piping/tubing to a reservoir (such as a  bottle) to hold the aqueous wrinkle control composition.  Powered sprayers may include, but are not limited to,  centrifugal or positive displacement designs.  It  is preferred  that the powered sprayer be powered by a portable  DC  electrical current from either disposable batteries (such as  commercially available alkaline batteries) or rechargeable  battery units (such as commercially available nickel cad- mium battery units). Powered sprayers may also be powered  by standard AC power supply available in most buildings.  The discharge nozzle design can be varied to create specific  spray characteristics (such as spray diameter and particle  size).  It  is also possible to have multiple spray nozzles for  different spray characteristics. The nozzle may or may not  contain an adjustable nozzle shroud that would allow the  spray characteristics to be altered.  For the piston spray dispenser, as the trigger is released,  the spring acts on the piston to return it to its original  position. For the bellows spray dispenser, the bellows acts as  the spring to return to its original position. This action causes  a vacuum in the chamber. The responding fluid acts to close  the outlet valve while opening the inlet valve drawing  product up to the chamber from the reservoir.  The article of manufacture herein can also comprise a  non-manually operated spray dispenser. By "non-manually  operated" it is meant that the spray dispenser can be manu› ally activated, but the force required to dispense the wrinkle  control composition is provided by another, non-manual  means. Non-manually operated sprayers include, but are not  limited to, powered sprayers, air aspirated sprayers, liquid  aspirated sprayers, electrostatic sprayers, and nebulizer  sprayers. The wrinkle control composition is placed into a  spray dispenser in order to be distributed onto the fabric.  For smaller fluid ounce sizes (such as 1 to 8 ounces), a  finger pump can be used with canister or cylindrical bottle.  The preferred pump for this application is the cylindrical  Euromist IIfi from Seaquest Dispensing. More preferred are  those with precompression features.  Most preferably, the spray dispenser is a manually acti› vated trigger-spray dispenser. Said trigger-spray dispenser  comprises a container and a trigger both of which can be  constructed of any of the conventional material employed in  fabricating trigger-spray dispensers, including, but not lim- ited to: polyethylene; polypropylene; polyacetal; polycar› bonate; polyethyleneterephthalate; polyvinyl chloride; poly› styrene; blends of polyethylene, vinyl acetate, and rubber  elastomer. Other materials can include stainless steel and  glass. A preferred container is made of clear, e.g. polyeth› ylene terephthalate. The trigger-spray dispenser does not  incorporate a propellant gas into the odor-absorbing  composition, and preferably it does not include those that  will foam the wrinkle control composition. The trigger-spray  dispenser herein is typically one which acts upon a discrete  amount of the wrinkle control composition itself, typically  by means of a piston or a collapsing bellows that displaces  the composition through a nozzle to create a spray of thin  liquid. Said trigger-spray dispenser typically comprises a  pump chamber having either a piston or bellows which is  movable through a limited stroke response to the trigger for  varying the volume of said pump chamber. This pump  chamber or bellows chamber collects and holds the product  for dispensing. The trigger spray dispenser typically has an  outlet check valve for blocking communication and flow of  fluid through the nozzle and is responsive to the pressure  inside the chamber. For the piston type trigger sprayers, as  the trigger is compressed, it acts on the fluid in the chamber  and the spring, increasing the pressure on the fluid. For the  bellows spray dispenser, as the bellows is compressed, the  pressure increases on the fluid. The increase in fluid pressure  in either trigger spray dispenser acts to open the top outlet  check valve. The top valve allows the product to be forced  through the swirl chamber and out the nozzle to form a  discharge pattern. An adjustable nozzle cap can be used to  vary the pattern of the fluid dispensed.  The preferred trigger sprayers are the blue inserted  Gualafi sprayer, available from Berry Plastics Corp., or the  Calmar TS800-1Afi, TS1300fi, and TS-800-2fi, available  from Calmar Inc., because of the fine uniform spray  characteristics, spray volume, and pattern size. More pre› ferred are sprayers with precompression features and finer  spray characteristics and even distribution, such as Yoshino  sprayers from Japan. Any suitable bottle or container can be  used with the trigger sprayer, the preferred bottle is a 17  fl-oz. bottle (about 500 ml) of good ergonomics similar in  shape to the Cinchfi bottle.  It  can be made of any materials  such as high density polyethylene, polypropylene, polyvinyl  chloride, polystyrene, polyethylene terephthalate, glass, or  any other material that forms bottles. Preferably, it is made  of high density polyethylene or clear polyethylene tereph› thalate.  ing pump-spray dispensers, including, but not limited to:  polyethylene; polypropylene; polyethyleneterephthalate;  blends of polyethylene, vinyl acetate, and rubber elastomer.  A  preferred container is made of clear, e.g., polyethylene  terephthalate. Other materials can include stainless steel.
