Two-piece pipe end cap

Abstract

A two-piece end cap for an industrial pipe is provided. The end cap comprises a planar end wall and a flexible side wall extending about the periphery of the end wall, the side wall having a lip extending inwardly from the bottom thereof, the lip having a groove therein within which the periphery of the planar end wall is seated, an oblique surface being present along the top of the lip extending downwardly from the side wall toward the end wall and terminating adjacent a lateral edge of the lip, and the side wall having at least one annular ridge extending about the inner periphery of the side wall for engagement with an exterior surface of a pipe upon insertion of the pipe into the end cap, the annular ridge being in a plane which is parallel to the planar end wall.

1 . A two-piece end cap for a pipe, comprising a planar end wall and a flexible side wall extending about the periphery of the end wall, the side wall having a lip extending inwardly from the bottom thereof, the lip having a groove therein within which the periphery of the planar end wall is seated, an oblique surface being present along the top of said lip extending downwardly from said side wall toward said end wall and terminating adjacent a lateral edge of the lip, and the side wall having at least one annular ridge extending about the inner periphery of the side wall for engagement with an exterior surface of a pipe upon insertion of the pipe into the end cap, said annular ridge being in a plane which is parallel to the planar end wall. 
     
     
         2 . The two-piece end cap of  claim 1 , wherein said side wall is formed from an extruded sheet having opposing ends joined together. 
     
     
         3 . The two-piece end cap of  claim 1 , wherein said side wall includes multiple annular ridges. 
     
     
         4 . The two-piece end cap of  claim 1 , wherein said at least one annular ridge includes an air channel. 
     
     
         5 . The two-piece end cap of  claim 1 , wherein said at least one annular ridge comprises a series of annular ridges each having an alternating ridge-trough configuration. 
     
     
         6 . The two-piece end cap of  claim 1 , wherein said ridge includes an air channel extending along the extent thereof.
