RISER CAP AND IRRIGATION PIPING SYSTEM USING SAME
First Claim
1. An irrigation pipe system, comprising:
- a tubular coupler member having at least one open end adapted for connection to a fluid transport pipe, the tubular coupler member having a tubular riser adapter member in fluid communication with a central region thereof, the tubular riser adapter member having an externally threaded surface;
a riser cap member having a central tubular section defining a generally cylindrical bore for receiving a sprinkler riser, the central tubular section having open top and bottom ends, and an annular skirt coaxial with the central tubular section and having an inner diameter larger than an inner diameter of the central tubular section, the annular skirt having an inner surface having internal threads threadably connectable with the externally threaded surface of the tubular riser adapter member; and
a seal;
whereby the riser cap member is connected to the tubular riser adapter member of the tubular coupler member by inserting the bottom end of the central tubular section inside of the tubular riser adapter member and threadably connecting the internal threads of the annular skirt to the externally threaded surface of the tubular riser adapter member, with the seal disposed between the tubular riser adapter member and the riser cap member.

Abstract
A polymeric riser cap member includes a central tubular section defining a generally cylindrical bore for receiving a sprinkler riser, the central tubular section having open top and bottom ends, and an annular skirt coaxial with the central tubular section and having an inner diameter larger than an inner diameter of the central tubular section. The annular skirt has an inner surface having internal threads threadably connectable with the externally threaded surface of a tubular riser adapter member of a tubular coupler. The bottom end of the central tubular section has an annular projection disposed opposite and spaced from a portion of the annular skirt. The riser cap member includes an annular recess adapted to receive a seal located in a wall extending laterally between the annular skirt and the annular projection.
