A spray extension device for a spray can includes at least a pair of telescopable extension tubes fitted to and in fluid communication with the valve stem of a spray can. Advantageously, the extension tubes are fitted to a closure cap which, in turn, is fitted to the valve stem, and, thereby, in fluid communication with the interior of the can. Depressing of the closure cap causes the valve stem to issue fluid therethrough, into the tubes.

1. An extension spray device for an internally pressurized aerosol spray can having a moveable tubular control valve stem extending upwardly from the top of the can and generally aligned with the central axis of the can, comprising:a first closure cap, said closure cap having an inlet socket dimensioned for gripping removable fitment to the valve stem, an outlet socket, and a conduit for communicating fluid content of the spray can from the inlet socket to the outlet socket, wherein movement of said closure cap in a direction towards said spray can causes said valve stem to move and permit fluid to be discharge from said aerosol spray can, and a spray extension assembly, the assembly being removably mountable to the outlet socket of said closure cap and including: a first spray tube, the first spray tube being axially elongated and having rearward and forward end portions, the rearward end portion being dimensioned for gripping removable fitment with the outlet socket of said closure cap and the forward end portion being provided with a radially inwardly extending shoulder, and a second spray tube, the second spray tube being axially elongated and having rearward and forward end portions, the rearward end portion being provided with a radially outwardly extending first abutment, and wherein said second spray tube is dimensioned for coaxial slidable fitment within said first spray tube, said first abutment being dimensioned to engage said shoulder and prevent removal of the second spray tube from the first spray tube. 2. The extension spray device of claim 1 which further comprises:a second closure cap, said second closure cap having an inlet socket dimensioned for gripping removable fitment with the forward end portion of said second spray tube, discharge outlet, and a fluid conduit for communicating fluid received from the second spray tube to the discharge outlet. 3. The extension spray device of claim 1 wherein the fluid conduit in said first closure cap includes first and second portions which are substantially at right angles to one another wherein to change the direction of the fluid discharged from said spray extension assembly.4. The extension spray device of claim 3 wherein the second portion of said fluid conduit in said first closure cap is coaxial with the first and second spray tubes.5. The extension spray device of claim 1 whereinthe spray extension assembly includes an axially elongated third spray tube having rearward and forward end portions and dimensioned for coaxial slidable movement within the second spray tube, the rearward and forward end portions of the third and second tubes being provided, respectively, with an abutment that extends radially outwardly and radially inwardly with the inwardly extending abutment of the second tube being adapted to engage the outwardly extending abutment of the third tube to prevent removal of the third spray tube from the spray tube, and the extension spray device further comprises a second closure cap, the second closure cap having an inlet socket dimensioned for gripping removable fitment about the forward end of said third spray tube. 6. The extension spray device of claim 5 wherein the second closure cap further includes a discharge outlet, and a fluid conduit for communicating fluid received between the inlet and outlets thereof wherein to discharge fluid received from the third tube outwardly of the spray assembly.7. A kit for use with an aerosol spray can having a movable control valve actuator stem projecting upwardly from an end cap formed at one end of the spray can and movable in a direction towards the end cap, the kit comprising:a closure cap to mount to the valve actuator stem and move with the stem towards the end cap, the closure cap comprising a substantially solid generally cylindrical body having an inlet socket dimensioned for gripping removable fitment to the valve stem, an outlet socket, and a conduit for communicating fluid content of the spray can from the inlet socket to the outlet socket, and a spray extension assembly to mount to the outlet socket of the of the closure cap, the spray extension assembly including inner and outer generally cylindrical spray tubes each having a rearward and forward end portion, the rearward end portion of said outer spray tube, being dimensioned for gripping removable fitment with the outlet socket of said closure cap, and engagement structure operating the forward and rearward end portions of said outer and inner spray tubes, and wherein said tubes are disposed in coaxial relation and movable relative to one another, and said engagement structure operates to prevent removal of the inner spray tube from the outer spray tube. 8. The kit as claimed in claim 7, further comprising a second closure cap, said second closure cap including an inlet socket for grippingly removably engaging the outer periphery of the forward end portion of said inner spray tube.9. The kit as claimed in claim 8, wherein said second closure cap comprises a generally solid body and includes an outlet socket and a fluid conduit extending between the inlet and outlet sockets thereof for communicating fluid therethrough, the inlet socket of said second closure cap being in fluid communication with the valve stem when the first closure cap is fitted to the valve stem and the second closure cap is fitted to the spray tube.10. The kit as claimed in claim 7, wherein said spray assembly includes at least one spray tube disposed in movable sliding coaxial relation between said inner and outer spray tubes, and second engagement structure operating between the at least one spray tube and said inner and outer tubes for preventing unwanted removal of said at least one spray tube from said spray assembly.
