Flux applicator brush and flux container system

摘要

A system for applying a pipe joining agent, such as flux, primer or adhesive, to pipe structure surfaces. The system includes a male brush that cooperates with a female brush that is removably mounted on a container than contains the agent to be applied. The male brush can be inserted through the female brush and into the container to pick up the agent. As the male brush is withdrawn from the container, the female brush wipes excess agent from the male brush so that the female brush picks up agent thereon. The male brush can then be inserted into the end of a pipe structure to apply the agent to the interior surface of the pipe structure. Also, the female brush can be removed from the container and then inserted over the end of a pipe structure to apply the agent to the exterior surface of a pipe structure.

主权项

1. A pipe joining agent container system, comprising:
a container having a bottom wall and a side wall connected to the bottom wall and extending upwardly from the bottom wall to an edge defining an open top of the container, the bottom wall and the side wall defining an interior space; a pipe joining agent disposed within the interior space of the container; a female pipe joining agent applicator brush removably associated with the container and configured for applying pipe joining agent to an exterior surface of a first cylindrical pipe structure that has a nominal exterior diameter, the female pipe joining agent applicator brush including:
a support structure, the support structure being configured for removable mounting on the container, and the support structure includes a sleeve and a first handle, the sleeve having a first axial end adjacent to the open top and a second axial end within the interior space;a cylindrical female brush connected to the support structure, the female brush including an arrangement of bristles; the bristles extend generally radially inward toward one another between the first axial end and the second axial end, and the bristles include outer radial ends connected to the sleeve and inner radial ends that define a passage through the cylindrical female brush, and the bristles are configured to wipe pipe joining agent and retain the wiped pipe joining agent; andthe passage has a diameter that is approximately equal to the nominal exterior diameter of the first cylindrical pipe structure; and a male pipe joining agent applicator brush that is configured for applying pipe joining agent to an interior surface of a second cylindrical pipe structure that has a nominal exterior diameter, the male pipe joining agent applicator brush including:
a second handle having an outer surface;a cylindrical male brush connected to the second handle and that extends circumferentially around the outer surface thereof, the male brush including a first axial end, a second axial end, and an arrangement of second bristles; the second bristles extend generally radially outward from the outer surface of the second handle between the first axial end and the second axial end of the male brush, and the second bristles include inner radial ends adjacent to the outer surface and outer radial ends;the cylindrical male brush has an outer diameter defined by the outer radial ends of the second bristles, and the outer diameter is large enough to contact the interior surface of the second cylindrical pipe structure;andthe outer diameter of the cylindrical male brush is larger than the diameter of the passage of the cylindrical female brush; the bristles of the female brush are soft enough to bend during wiping of the male brush and when applying the pipe joining agent and have enough elasticity to substantially return back to their original shape.
