41  US 6,503,413 B2  42  The container and the pump mechanism can be con› structed of any conventional material employed in fabricat- The pump mechanism comprises a pump chamber of  substantially fixed volume, having an opening at the inner  end thereof. Within the pump chamber is located a pump  stem having a piston on the end thereof disposed for  reciprocal motion in the pump chamber. The pump stem has  a passageway there through with a dispensing outlet at the  outer end of the passageway and an axial inlet port located  inwardly thereof.  The article of manufacture herein comprises a spray  dispenser. The fabric wrinkle control composition is placed  into a spray dispenser in order to be distributed onto the  fabric. Said spray dispenser for producing a spray of liquid  droplets can be any of the manually activated means as is  known in the art, e.g. trigger-type, pump-type, non-aerosol  self-pressurized, and aerosol-type spray means, for treating  the wrinkle control composition to small fabric surface areas  and/or a small number of garments, as well as non-manually  operated, powered sprayers for conveniently treating the  wrinkle control composition to large fabric surface areas  and/or a large number of garments. The spray dispenser  herein does not normally include those that will substantially  foam the clear, aqueous wrinkle control composition.  It  has  been found that the performance is increased by providing  smaller particle droplets. Desirably, the Sauter mean particle  diameter is from about 10  µm  to about 120  µm,  more  preferably, from about 20  µm  to about 100  µm.  Dewrinkling  benefits are improved by providing small particles  (droplets), as discussed hereinbefore, especially when the  surfactant is present.  More preferably, the spray dispenser is a non-aerosol,  manually activated, pump-spray dispenser. Said pump-spray  dispenser comprises a container and a pump mechanism  which securely screws or snaps onto the container. The  container comprises a vessel for containing the aqueous  wrinkle control composition to be dispensed.  Preferably the spray dispenser can be a self-pressurized  non-aerosol container having a convoluted liner and an  elastomeric sleeve. Said self-pressurized dispenser com- prises a liner/sleeve assembly containing a thin, flexible  radially expandable convoluted plastic liner of from about  0.010 to about 0.020 inch thick, inside an essentially cylin› drical elastomeric sleeve. The liner/sleeve is capable of  holding a substantial quantity of wrinkle control composi- tion product and of causing said product to be dispensed. A  more complete description of self-pressurized spray dis› pensers can be found in U.S. Pat. No. 5,111,971, Winer,  issued May 12, 1992, and U.S. Pat. No. 5,232,126, Winer,  issued Aug. 3, 1993; both of said references are herein  incorporated by reference. Another type of aerosol spray  dispenser is one wherein a barrier separates the wrinkle  control composition from the propellant (preferably com› pressed air or nitrogen), as disclosed in U.S. Pat. No.  4,260,110, issued Apr. 7, 1981, and incorporated herein by  reference. Such a dispenser is available from EP Spray  Systems, East Hanover,  N.J.  As  used herein, the phrase "in association with" means the  set of instructions are either directly printed on the container  itself or presented in a separate manner including, but not  limited to, a brochure, print advertisement, electronic  advertisement, and/or verbal communication, so as to com› municate the set of instructions to a consumer of the article  of manufacture. The set of instructions preferably comprises  the instruction to apply an effective amount of the  composition, preferably by spraying, to provide the indi› cated benefit, e.g., wrinkle reduction and/or reduction of  malodor impression.  The stable, aqueous compositions of the present invention  can also be used in an article of manufacture comprising said  composition contained in a spray dispenser. Preferably the  articles of manufacture are in association with instructions  for how to use the composition to treat surfaces, espeically  surfaces having malodor impression, or wrinkled fabrics  including, e.g., the manner and/or amount of composition to  spray, and the preferred ways of stretching and/or smoothing  of the fabrics, as will be described with more detailed herein  below.  It  is important that the instructions be as simple and  clear as possible, so that using pictures and/or icons is  desirable. Thus a set of instructions can comprise an instruc› tion to reduce malodor impression on surfaces, especially  fabrics, by following one or more of the methods described  hereinbefore. A set of instructions can also comprise an  instruction to reduce the appearance of wrinkles in fabrics  by carrying out one or more of the methods described  hereinbefore.  The spray dispenser can be an aerosol dispenser. Said  aerosol dispenser comprises a container which can be con› structed of any of the conventional materials employed in  fabricating aerosol containers. The dispenser must be  capable of withstanding internal pressure in the range of  from about 20 to about 110 p.s.i.g., more preferably from  about 20 to about 70 p.s.i.g. The one important requirement  concerning the dispenser is that it be provided with a valve  member which will permit the clear, aqueous de-wrinkle  composition contained in the dispenser to be dispensed in  the form of a spray of very fine, or finely divided, particles  or droplets. The aerosol dispenser utilizes a pressurized  sealed container from which the clear, aqueous de-wrinkle  composition is dispensed through a special actuator/valve  assembly under pressure. The aerosol dispenser is pressur- ized by incorporating therein a gaseous component generally  known as a propellant. Common aerosol propellants, e.g.,  gaseous hydrocarbons such as isobutane, and mixed halo› genated hydrocarbons, can be used. Halogenated hydrocar› bon propellants such as chlorofluoro hydrocarbons have  been alleged to contribute to environmental problems, and  are not preferred. When cyclodextrin is present hydrocarbon  propellants are not preferred, because they can form com› plexes with the cyclodextrin molecules thereby reducing the  availability ofuncomplexed cyclodextrin molecules for odor  absorption. Preferred propellants are compressed air,  nitrogen, inert gases, carbon dioxide, etc. A more complete  description of commercially available aerosol-spray dis› pensers appears in U.S. Pat. No. 3,436,772, Stebbins, issued  Apr. 8, 1969; and U.S. Pat. No. 3,600,325, Kaufman et al.,  issued Aug. 17, 1971; both of said references are incorpo› rated herein by reference.  compositions of the present invention are preferably con› centrated. Also, for these methods, the compositions can  contain a  DEQA  compound, which will typically enhance  the softness of the fabrics being treated. In this embodiment,  the method comprises the steps of placing fabrics in a  laundry wash and/or rinse solution and then adding the  composition of the present invention to the wash and/or  rinse solution. These methods include methods of reducing  malodor impression on the fabrics in the wash and/or rinse  solutions, and/or methods of reducing the appearance of  wrinkles on the fabrics in the wash and/or rinse solutions.  This reduction is, of course, relative to the amounts of  malodor impression and/or wrinkles on the fabrics before  placing them in the wash and/or rinse solutions.  III.
