Abstract
A pipe lubricant applicator includes a rotatable housing to receive a lubricant, the housing having a central axis and a concave inner surface and wherein an axis extending radially from the central axis of the housing intersects the concave inner surface at an angle that is not 90°.
Claims18
A pipe lubricant applicator comprising:
- a rotatable housing to receive a lubricant, the housing having a central axis and a concave inner surface;
- wherein an axis extending radially from the central axis of the housing intersects the concave inner surface at an angle that is not 90°.
A pipe lubricant applicator comprising:
- an applicator housing to receive a pipe lubricant, the housing including a central axis, an inner surface, and an outer surface;
- an opening in the housing through the inner and outer surfaces to receive the pipe lubricant;
- wherein the inner surface comprises a plurality of concave surfaces;
- and
- wherein an axis extending radially from the central axis intersects any one of the plurality of concave inner surfaces at an obtuse angle.

A method for applying a coating of lubricant on pipe threads, the method comprising:
- rotating a housing;
- supplying the lubricant to an interior volume of the housing;
- and
- forcing the lubricant toward a concave inner surface of the housing such that substantially all of the lubricant contacts the concave inner surface along a vector including an obtuse angle with the concave inner surface;
- whereby the lubricant is funneled in the direction of the obtuse angle toward an opening in the housing.
