  • Patent number: 6131234
    Abstract: A flower-like bathing implement which includes an elastic tube of net arranged into the shape of an axially peripherally wrinkled short cylinder; a first binding element inserted through the elastic tube of net and tied up, forming a first tied point at the elastic tube; a second binding element wound round the elastic tube of net and tied up, forming a second tied point spaced from the first tied point at a distance, the second binding element having a part extended over top and bottom sides of the elastic tube and tied up, forming a third tied point at the elastic tube of net adjacent the second tied point; a first expansion portion formed of a part of the elastic tube of net between the first tied point and the second tied point; a second expansion portion formed of the other part of the elastic tube of net and shaped like a flower expanded in all directions from the second binding element.

  • Patent number: 6112363
    Abstract: A bath belt including: a main body having a first elastic mesh tube which is pushed and gathered so that a periphery of the first elastic mesh tube is axially successively crimped into a waved shape; a pair of first binders respectively disposed on two opposite sides of the main body; and several second binders spaced from each other and disposed on the first elastic mesh tube for binding the same. The portions of the first elastic mesh tube between the second binders are expanded to a series of ball-like bodies. The main body further includes at least one second elastic mesh tube positioned between one end of the first elastic mesh tube and one of the first binders. The second elastic mesh tube is wound into an annular shape. The second elastic mesh tube is passed through the hole of the first elastic mesh tube and partially extends outside of the first elastic mesh tube.

  • Patent number: 6098236
    Abstract: A bath strip which includes an elastic tube of net transversely stretched, two first flexible binding elements inserted through the elastic tube of net and tied up, forming two loop-like handle means at two opposite ends of the transversely stretched elastic tube of net, and a plurality of second flexible binding elements respectively wound round the transversely stretched elastic tube of net and tied up, separating the transversely stretched elastic tube of net into a longitudinal series of spherical portions.

  • Patent number: 6092258
    Abstract: A bath brush including an elastic mesh tube, a grip member and a binding member. The mesh tube is axially squeezed and compressed, whereby the circumference thereof is continuously waved and crimped. The grip member is disposed on an outer side of the elastic mesh tube and formed with a first fixing portion and a second fixing portion spaced from each other by a predetermined distance and at least one third fixing portion between the first and second fixing portions. The binding member has a predetermined length and flexibility and is formed with a first and a second binding sections spaced from each other by a predetermined distance, a pressing section between the first and second binding sections and at least one third binding section disposed on the pressing section. The number of the third binding section corresponds to the number of the third fixing portion.

  • Patent number: 5916408
    Abstract: A method for making a mittenlike bath scrubber includes an initial step in which a tubular net is transformed into a wavy net by a heat rolling device. The wavy net is then flattened such that the wavy net has an upper layer and a lower layer. The flattened wavy net has a closed end which is formed by the fusion of the corresponding portions of the upper layer and the lower layer. The flattened wavy net has an open end which is opposite to the closed end and is provided with a strap. The flattened wavy net is turned inside out to become the mittenlike bath scrubber.

  • Patent number: 5758386
    Abstract: A bath scrubber comprises an elastic webbed tube, two first lashing members and one second lashing member. The webbed tube has a periphery which is pleated continuously in the direction of the longitudinal axis of the webbed tube. The first lashing members are secured respectively to both ends of a first radial direction of the webbed tube. The second lashing member is secured to the periphery of the webbed tube such that the second lashing member is perpendicular to the first radial direction of the webbed tube so as to enable the webbed tube to form two expanded integral parts of different sizes.

  • Patent number: 5709434
    Abstract: A method for making a spherical bath scrubber comprises a tubular network body and two bracing members separated at a predetermined interval for exerting a tensile force on the tubular network body embracing the bracing members. The centers of two stretched sides of the tubular network body are lashed to facilitate the further stretching of two stretched sides of the tubular network body in an alternating and superimposing manner so as to enable the tubular network body to expand from the lashing points to form the spherical bath scrubber.
