Abstract
Abstract A nozzle for applying filler material to a corner surface is provided having a generally cylindrical barrel. One end of the barrel has three beveled surfaces which taper to form a triangular spear shape. A central bore extends longitudinally throughout the extent of the barrel and forms a tip opening at the tapered end and a supply opening at the opposite end. Filler material proceeds through the central bore and out the tip opening on to the surface to which it is applied.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
A nozzle for the distribution of filler material in a corner formed by the intersection of two generally perpendicular surfaces comprising barrell means having a tapered end, said barrel means having a cross-section area which continuously decreases toward said tapered end, said tapered end formed from three beveled surfaces, and central bore means extending longitudinally through the extent of said barrel means, said central bore means forming a supply opening and a tip opening, said tip opening provided at the intersection of said three beveled surfaces at said tapered end, said tip opening being provided at an angle of approximately 45° to a first of said three beveled surfaces and extending to the intersection of the other two of said three beveled surfaces, said other two beveled surfaces sized and positioned to fit within a corner formed by the intersection of said two generally perpendicular surfaces, said first of said three beveled surfaces adapted to smooth the flow of filler material from said nozzle.
Claim 2
Dependent Claim
164 words
A nozzle for the distribution of filler material in a corner formed by the intersection of two generally perpendicular surfaces comprising barrell means having a tapered end, said barrel means having a cross-section area which continuously decreases toward said tapered end, said tapered end formed from three beveled surfaces, and central bore means extending longitudinally through the extent of said barrel means, said central bore means forming a supply opening and a tip opening, said tip opening provided at the intersection of said three beveled surfaces at said tapered end, said tip opening being provided at an angle of approximately 45° to a first of said three beveled surfaces and extending to the intersection of the other two of said three beveled surfaces, said other two beveled surfaces sized and positioned to fit within a corner formed by the intersection of said two generally perpendicular surfaces, said first of said three beveled surfaces adapted to smooth the flow of filler material from said nozzle.
Claim 3
Dependent Claim
20 words

Claim 4
Dependent Claim
23 words
The nozzle of claim 2 further comprising means adjacent to said supply opening for securing said nozzle to a container of filler material.
Claim 5
Dependent Claim
28 words
The nozzle of claim 2 further comprising means adjacent to said supply opening for securing said nozzle to an existing nozzle provided on a container of filler material.
