  • Patent number: 6601259
    Abstract: A method for making a bath brush involves the fitting of a tubular net main body with two support rods which are separated from each other by a predetermined distance. The tubular net main body is then laterally stretched before a brush handle is disposed in the middle portion of one side of the two support rods. A tightening member is used to wrap the tubular net main body which is then tightened to locate on the brush handle. The stretched main body is gradually pulled out of the two support rods such that the main body is fastened with one side of the brush handle, and that the main body expands at the tightening point serving as a center to form a loose bath ball.

  • Publication number: 20030001428
    Abstract: A method for making a bath scrubber for use in cleaning the body skin involves a tubular net main body which is fitted over two support members separated from each other by a predetermined distance. The main body is then tightened. The present invention is characterized in that the main body is pulled alternatively with one hand toward one direction and other hand toward other direction, and each time when the tubular net body is pulled, a portion of the tubular body is pulled out of the two support members synchronously until the tubular net body is completely pulled out of the two support members, thereby enabling the main body to expand along the tightening point to form a spherical body.

  • Patent number: 6149243
    Abstract: A method for making a fruit-shaped bath scrubber makes use of an elastic tubular net having two open ends. One of the open ends is first folded toward other end such that the two open ends form a combination end, and that other end of the tubular net forms a first folding end. The combination end is then folded toward the first folding end. A tail end of the tubular net is then repeatedly folded toward the first folding end until the tubular net is entirely folded to be located beside the first folding end. A ring is partially inserted into the first folding end before a lashing strap is put through the top edge of the folded portion of the tubular net, the first folding end and the ring. The lashing strap is tightened to form the fruit-shaped bath scrubber.
