Molded tube with a sealed end

Abstract

The invention provides a molded tube with a sealed end. When the tube body is placed front of a press mold, an end of the tube body is heated while being rotated until the ends is moldable. Thereafter, the end portion of the tube is shaped in a manner that an inner wall of the end portion of the tube body tapes outwardly, so that a wall thickness of the tube body is smaller than that of the end portion. A plurality of threads or a groove is further formed on an external surface of the end portion of the tube to further fastening an additional element.

What is claimed is:  
     
         1 . A molded tube with a sealed end, the molded tube comprising: 
 a tube body, having a first wall thickness;    a sealed end connected to the tube body and having a second wall thickness, wherein an inner wall of the sealed end tapers toward outwardly, the second wall thickness being larger than the first wall thickness; and    a plurality of thread or a groove, optionally formed on an external surface of the sealed end.
