1. A fillet forming caulking tool for use with a caulking cartridge having a conical plastic nozzle said tool comprising:
- (a) a conical body member terminated at its larger end with means to retain said caulking tool on said plastic nozzle and at its smaller end with a partial closure;
(b) a fillet forming member having planar surfaces attached to said smaller end; and
said planar surfaces of said forming member lying essentially on the centre line of said conical body member;
(c) an orifice in said closure of said body member immediately beneath said surface of said fillet forming member;
wherein said fillet forming member is a flexible resilient triangular member having two edges at approximately forty five degrees to the said centre line of said body member and a third edge substantially at right angles to said centre line of said body member.

Abstract
A tool is provided to fit on the plastic nozzle of standard caulking cartridges. The tool consists of a tapered hollow body terminated in a planar sqeegee member which has two edges at 45° to the center line of the body. An orifice under the sqeegee permits caulking compound to emerge from the tool where it is shaped into a fillet for sealably joining two surfaces which are at right angles to each other. The sqeegee wipes the surfaces clean except at the junction of the surfaces where the fillet is formed.

6. A fillet forming caulking tool for use in association with a caulking cartridge having a conically tapered plastic nozzle, said tool designed to produce a fillet of caulking material in a joint between two adjacent surfaces lying at an angle of less than 180°
- with respect to each other said tool comprising;
(a) a conical body member terminated at its larger end with an outwardly extending flange; (b) a fillet forming member having planar surfaces attached to the smaller end of said conical body member, a surface of said fillet forming member lying essentially on the centre line of said conical body member; (c) the smaller end of said conical body member being closed on each side of said fillet forming member but having an orifice adjacent a surface of said fillet forming member; wherein said fillet forming member is a flexible resilient scraper of essentially triangular form having two edges at approximately forty five degrees to said centre line of said conical body member with the junction of said two edges forming an apex lying on said centre line, said apex being truncated to provide a curved fillet forming edge slightly beyond the smaller end of said conical body member and a third edge at approximately ninety degrees to said centre line whereby said two edges engage said adjacent surfaces being joined during operation. - View Dependent Claims (7, 8)

9. A fillet forming caulking tool comprising a caulking cartridge having a conically tapered plastic nozzle and a removeable forming tool having;
-
(a) a conical body member terminated at its larger end with means to retain said forming tool on said plastic nozzle and at its smaller end with a partial closure; (b) a fillet forming member having a planar surface attached to said smaller end;
the planar surface of said forming member lying essentially on the centre line of said conical body member;(c) an orifice in said body member immediately beneath said surface of said fillet forming member; wherein said planar member is a flexible resilient triangular member having two edges at approximately forty five degrees to the said centre line of said body member and a third edge substantially at right angles to said centre line of said body member.

10. A fillet forming caulking tool including a caulking cartridge having a conically tapered plastic nozzle and a removeable forming tool for forming a fillet of caulking material in a joint between two adjacent surfaces lying at an angle of less than 180°
- with respect to each other said forming tool comprising;
(a) a conical body member terminated at its larger end with an outwardly extending flange; (b) a planar fillet forming member attached to the smaller end of said conical body member, a surface of said fillet forming member lying essentially on the centre line of said conical body member; (c) the smaller end of said conical body member being closed on each side of said planar fillet forming member but having an orifice adjacent a surface of said planar fillet forming member; wherein said planar fillet forming member is a flexible resilient scraper of essentially triangular form having two edges at approximately forty five degrees to said centre line of said conical body member with the junction of said two edges forming an apex lying on said centre line, said apex being truncated to provide a curved fillet forming edge slightly beyond the smaller end of said conical body member and a third edge at approximately ninety degrees to said centre line whereby said two edges engage said adjacent surfaces being joined during operation.
