Abstract

A lid for a distribution manifold is described where the manifold has an inlet opening defining an axis, access opening opposite the inlet and a plurality of radially extending outlet ports. The lid for the access opening includes a mounting member adapted to couple the lid to the manifold to close the access opening, a cone coupled to the mounting member and extending axially toward the inlet opening of the manifold when the lid is coupled to the manifold, and a single piece retainer adapted to secure the cone to the mounting member without additional fasteners.

Claims

1. A lid for a distribution manifold, the manifold having an inlet opening defining an axis, access opening opposite the inlet and a plurality of radially extending outlet ports, the lid comprising:

a mounting member adapted to couple the lid to the manifold to close the access opening, the mounting member haying a top wall and a downwardly depending inner annular wall;

a cone coupled to the mounting member and extending axially toward the inlet opening of the manifold when the lid is coupled to the manifold, the cone haying a cone shaped wall forming a cone tip and a cylindrical wall disposed radially inward from the inner annular wall of the mounting member; and

a single piece retainer adapted to secure the cone to the mounting member without additional fasteners, the retainer being a cylindrical ring positioned between the inner annular wall of the mounting member and the cylindrical wall of the cone and adapted to secure the cone to the mounting member.

2. The lid as defined by claim 1 wherein the cone and mounting member define a hollow interior.

3. The lid as defined by claim 1 wherein the cone cylindrical wall has a lip at a distal end thereof trapped by the retaining ring to hold the cone in place relative to the mounting member.

4. The lid as defined by claim 1 wherein the retaining ring and the inner annular wall have complementary snap engagement elements.

5. The lid as defined in claim 1 wherein the material for the mounting member is selected for its structural properties to mount on the manifold and the material for the cone is selected for wear resistance.

6. The lid as defined in claim 1 wherein the material for the mounting member is rigid injection moldable material.

7. The lid as defined in claim 6 wherein the material for the mounting member is a glass reinforced nylon.

8. The lid as defined in claim 1 wherein the material for the lid is selected from the group of thermoset elastomer and thermoplastic elastomer.

9. The lid as defined in claim 1 wherein the material for the lid is EPDM with UV stabilizers.
