A delivery device delivers a repair compound from a container with which it is assembled, and includes an integral smoothing tool or blade part. The container has an opening end finish, allowing the repair compound to enter, and extrude from, a nozzle part of the delivery device when the container is squeezed. A portion of the blade part exhibits transverse flexibility to facilitate smoothing of a deposited repair compound. The blade part also functions to effect closure of a terminal end orifice of the nozzle part, typically having a closure plug that enters the orifice to form a seal when disposed, by flexure of the blade part, in a closing position relative to the nozzle. Alternatively, the blade part may be capable of linear articulation to achieve closure at the nozzle orifice, and the sealing element may comprise a flat surface. The device enables one-handed setup, dispensing, closure, and smoothing of a deposited repair compound.

1. A repair-compound dispenser, comprised of a container that is at least partially compressible and is constructed for dispensing a repair compound contained therein from an opening thereof when the container is compressed; and a delivery device that enables a user to single-handedly dispense repair compound received from said container and also to smooth the dispensed repair compound deposited upon a receiving surface; said delivery device comprising: (A) a dispensing nozzle part that is constructed to communicate with said opening of said container and that has a passageway for the passage of repair compound received from said container, at said opening thereof, from a rearward inlet end of said passageway to a forwardly spaced outlet orifice thereof;(B) a smoothing blade part operatively associated with said nozzle part and having a blade portion that extends forwardly beyond said outlet orifice of said nozzle part passageway and that terminates in a generally rectilinear leading edge, said blade portion being constructed for forcing a repair compound into subsurface recesses and defects of a receiving surface on which the repair compound is deposited, and for smoothing the surface of the deposit; and(C) a closure element on said blade part that is constructed to close said forwardly spaced outlet orifice of said nozzle part passageway, said blade part being movable between a closing position, in which said closure element effectively closes said outlet orifice of said nozzle part, and at least one opening position in which said closure element is displaced from said outlet orifice to permit repair compound to pass therethrough, at least one of said nozzle part and said blade part having means for attachment to said container. 2. The dispenser of claim 1 wherein said container is in the form of a resilient tube or bottle, or is of substantially bellows-like form. 3. The dispenser of claim 1 wherein said nozzle part is integrally formed with said container, and wherein said means for attachment is on said blade part. 4. The dispenser of claim 1 wherein said nozzle part and said blade part comprise an assembly that is disengageable from said container and is attached thereto by said means for attachment, said nozzle part being constructed for engagement with said container at said opening thereof and for so communicating with said opening. 5. A hand-held delivery device that enables a user to single-handedly dispense a repair compound received from an attached container that is at least partially compressible and is constructed for dispensing a repair compound contained therein through an opening thereof when compressed, and also enables a user to smooth a repair compound dispensed from said delivery device and deposited upon a receiving surface, said delivery device comprising: (A) a dispensing nozzle part that is constructed for engagement with a container and that has a passageway for the passage of a repair compound received through a rearward inlet end of said passageway to a forwardly spaced outlet orifice thereof;(B) a smoothing blade part operatively associated with said nozzle part and having a blade portion that extends forwardly beyond said outlet orifice of said nozzle part passageway and that terminates in a generally rectilinear leading edge, said blade portion being constructed for forcing a repair compound into subsurface recesses and defects of a receiving surface on which the repair compound is deposited, and for smoothing the surface of the deposit; and(C) a closure element on said blade part that is constructed to close said forwardly spaced outlet orifice of said nozzle part passageway, said blade part being movable between a closing position, in which said closure element effectively closes said outlet orifice of said nozzle part, and at least one opening position in which said closure element is displaced from said outlet orifice to permit repair compound to pass therethrough, at least one of said dispensing nozzle part and said smoothing blade part having means thereon for attachment of said delivery device to such a container with said passageway of said nozzle part positioned to receive repair compound from an opening of the container. 6. The dispenser of claim 5 wherein said blade part is slidably mounted on said nozzle part for linear movement between said closing position and said at least one opening position of said blade part. 7. The dispenser of claim 6 wherein said nozzle part comprises a tubular portion located rearwardly of said outlet orifice and having a longitudinal axis, and wherein said blade part comprises a coaxial collar portion at least partially encircling said tubular portion of said nozzle part. 8. The dispenser of claim 7 wherein at least the exterior of said tubular portion of said nozzle part is substantially cylindrical, and wherein said collar portion is ring shaped, said delivery device being constructed to prevent relative rotation of said blade part on said nozzle part about said longitudinal axis of said tubular portion. 9. The dispenser of claim 7 wherein said collar portion has at least one structural feature for enhancing manual engagement thereof to thereby facilitate one-handed movement of said blade part between said closing position and said at least one opening position. 10. The dispenser of claim 5 wherein said blade part comprises a forwardmost, generally planar plate portion on which said rectilinear leading edge is provided, and a pair of laterally spaced rails connecting said plate portion to said collar portion and defining an open area therebetween, said outlet orifice of said passageway of said nozzle part being aligned with said open area of said blade part in said opening position thereof so as to permit passage of repair compound through said open area for deposit upon such a receiving surface. 11. The dispenser of claim 10 wherein said rails are constructed to permit resilient deflection of said plate portion of said blade part in opposite, transverse directions, generally normal to a plane thereof, in reaction to force applied thereto. 12. The dispenser of claim 11 wherein, in an unflexed position, said plate of said plate portion of said blade part is offset substantially from said longitudinal axis of said tubular portion of said nozzle part. 13. The dispenser of claim 5 wherein a bearing surface of said closure element on said blade part bears upon structure defining said outlet orifice of said nozzle part passageway to effect sealing of said outlet orifice in said closing position of said blade part. 14. The dispenser of claim 13 wherein said bearing surface of said closure element is substantially flat. 15. The dispenser of claim 14 wherein said nozzle part defines a channel extending inwardly from a forward end thereof and having a bottom wall in which said outlet orifice is formed, and wherein said blade part includes a rearward end portion that is slideably received in said channel of said nozzle part for movement between said closing position and said opening positions, said rearward end portion of said blade part overlying said outlet orifice, to block the flow of repair compound therethrough, in said closing position. 16. The dispenser of claim 13 wherein said closure element is of plug-like form and resides within said outlet orifice of said passageway in said closing position. 17. The dispenser of claim 13 wherein a gasket element is associated with one of said structure defining said outlet orifice of said nozzle part passageway and said closure element of said blade part, said gasket element lying in direct surface contact with the other of said structure defining said orifice and said closure element to promote air-tight sealing of said outlet orifice in said closing position. 18. The dispenser of claim 5 wherein said passage of said nozzle part includes a portion, proximate said outlet orifice thereof, that tapers in the direction of said orifice.
