Patent number: 6962198Abstract: The groundwater well sample device is an elongated, cylindrical sample tube, having a top end and a bottom end. The top end is open. A knothole is formed through the wall of the sample tube near the top end. The knothole is large enough for the knotted end of a string to be easily passed through the knothole. A zigzagging string-retaining slot is formed through the sample tube wall, extending from the knothole toward the top end of the sample tube. The string-retaining slot is slightly narrower than the diameter of a string. The string-retaining slot terminates in a stress-reducing aperture. In use, the knotted end of a string is passed through the knothole, and the string then pulled into the string-retaining slot where the string, slightly compressed within the slot, is held tightly in place. The top end is angled to allow easy access to the string-insertion aperture.Type: GrantFiled: August 21, 2003Date of Patent: November 8, 2005Inventor: Xiangjing Gao
