Abstract
Abstract A dispensing head or nozzle structure is mounted on a container of adhesive. The adhesive is especially adapted to adhere together edges of a flooring material. The nozzle structure is provided with an appropriate configuration and a guide structure so that a bead of adhesive is properly positioned between the edges of two pieces of sheet flooring and the adhesive will be distributed in a manner to properly adhere the edges together.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
177 words
A nozzle comprising a means for fastening the nozzle to an appropriate structure, an elongated body portion, a passageway extending completely through said body portion, the end of the body portion opposite from the fastening means being formed with four flat faces forming a tetrahedral-type nose structure, two fin structures protruding from and perpendicular to two opposite flat faces, the fin structure is substantially triangular in shape with one side of the triangle being in the plane of a flat face, the second side of the triangle being in a plane through the end of the nozzle, and the third side of the triangle being approximately 100* inclined from the plane of the flat face from which the fin perpendicularly protrudes, said two fins being in the same plane which extends perpendicularly from two opposite flat faces, an opening at the extreme end of the nozzle structure and interconnected with the passageway through the body of the nozzle structure, and said opening existing closely adjacent the juncture of one portion of the fins and their flat surface.
