Claim:
In an aerosol can spray delivery system of the standard type having a two-part spray button comprising: a pressurized aerosol can having a generally planar top cap in which is mounted a product release valve assembly, said top cap being secured to a top dome of said can at a rolled inner edge of said dome, said valve communicating internal of the can with a dip tube and communicating at an outlet end with a standard two-part finger-actuatable spray button of the type including a product passage therein in communication with the outlet end of said valve, and a small diameter lateral metering orifice disposed recessed in a lateral bore in the sidewall of said button, said metering orifice communicating with said button product passage but does not extend beyond the sidewall of said button. the improvement in said aerosol can spray delivery system comprising replacement of said standard two-part spray button with an improved button comprising: a) a spray button selected from a male button and a female button having a lateral bore communicating with a vertical central product passage bore; b) a short connector tube having a central bore and a first, inner end permanently secured in said lateral bore of said spray button in place of said standard button metering orifice, said connector tube terminates in an outer, second end and said connector tube includes a restriction disposed at one end therein defining a spray metering orifice; c) said bore of said connector tube is in communication with said button product passage; d) said connector tube has a length in the range of from about ¼″ to about 2″; e) an extension tube straw having a first, belled and flared end and a second outer end, said first belled and flared end is sized to receivingly engage and be securely retained on said connector tube outer end to provide remote, targeted delivery of product spray, produced from said connector tube, to and from the outer end of said extension tube without overspray, and said second outer end of said extension tube straw does not have a restricted orifice therein; and f) so that said connector tube is secured in said spray button lateral bore with its central bore opening and metering orifice coordinated with the button product passage to provide continuous flow of product from the can through the connector tube when the button is actuated to produce spray, said connector tube being sized for diameter and length to receivingly engage said extension tube straw for confined delivery of a controlled amount of product spray produced by said connector tube to a user-desired target without overspray.
