Definitions

  • the invention relates to a hair curler with an elongated bobbin, on which the hair is to be fixed with the aid of a tensioning band to be clamped between the longitudinal ends of the bobbin, the pins being molded onto the ends of the tensioning band during casting, as coupling and closure elements for insertion into the End holes of the winding body provided receiving holes are formed.
  • Such a hair wave developer is known from US-A-2 525 750.
  • Such bobbins are generally produced in a substantially cylindrical shape with a hyperboloidally increasing diameter at the longitudinal ends of the cylinders.
  • the hair is wrapped around the winding body and the wound hair is fixed by means of a tension band which is to be coupled to the longitudinal ends of the winding body with a certain elastic stretch.
  • This hair curler known from US-A-2 525 750 has a cast tension band which is provided with slits which do not penetrate the tension band before the hair curler is first used. Furthermore, the hair curler according to US-A-2 525 750 is designed as a cylindrical sleeve made of absorbent material such as cotton or paper.
  • the invention has for its object to reduce the effort for producing the tensioning straps and increase the chemical resistance of the straps.
  • this object is achieved according to the invention in that the winding body is injection-molded in a hollow manner and the openings formed on its end faces by mold cores are provided as receiving holes for the pins, and in that the tensioning band is made of a rubber-elastic, elastomeric polyurethane (PUR) manufactured by the injection molding process and the material elasticity of the tensioning strap is supplemented by formula elasticity, in particular by injected holes with essentially uniformly wide edge strips.
  • PUR rubber-elastic, elastomeric polyurethane
  • the invention makes it possible to obtain a tensioning band solely by spraying elastic plastic materials, the elasticity of which is sufficient for coupling with the winding body wound with hair, the material of which is chemically neutral to the application liquid or the corrugating agent and by the intended addition of the material elasticity
  • the elasticity of the formula must be stretched with a force that is sufficiently low for practical use.
  • the material elasticity is supplemented by injected holes.
  • the winding body is injection-molded in a hollow manner, it has a cavity running parallel to the central axis as a reservoir for a corrugating agent.
  • additional internal injection molding units such as cores or slides, are required to produce this cavity during spraying.
  • the latter tools result in holes on the end faces of the winding body which are not to be covered with hair, which holes are to be closed with the pins of the tensioning band, thereby preventing liquid waving agent from exiting the end face of the winding body when using liquid.
  • the pins provided for coupling the tensioning strap are molded onto the tensioning strap as closure elements for the (core) holes remaining on the end faces of the winding body in one operation during injection molding, the costs for producing and inserting otherwise customary sealing plugs in the case of hollow-molded winding bodies saved.
  • the injection molding of the pins as coupling and locking elements for insertion into the holes in the end faces of the winding body means practically no additional effort.
  • the material for the strap is:
  • Thermoplastic polyurethane elastomer produced by reacting a mixture of butanediol and a polymer diol with a molecular weight of 800 to 3000 on an ester and / or ether basis with diphenylmetanediisocyanate, the proportions of the starting materials being chosen according to the known prior art so that the resultant Product after thermoplastic processing at room temperature has a Shore hardness according to DIN 53505 of 75 to 85.
  • the tensioning strap 2 of FIG. 1 essentially consists of the edge strips 4 of diamonds 5 lined up with the tip.
  • the tensioning strap 3 of FIG. 2 consists of the edge strips 6 of circular holes 7 lined up with one another.
  • the tensioning straps 2 and 3 have at the longitudinal ends Pins 11 and 12, the tab 11 being assigned a grip tab 10.
  • the pins 11 and 12 which can be seen in particular in FIG. 3, are also molded on directly during the manufacture of the tensioning band after the injection molding process. Otherwise, in Fig. 3 in Side strap 13 shown have any configuration corresponding to FIG. 1 or 2.
  • the strap 13 with integrated pin 11, 12 engages in the application in the end receiving holes 17, 18 of the winding body of Fig. 4, which is injected as a hollow body or shaped in another way that at its longitudinal ends 15 and 16, for example a core or slider forth, holes 17 and 18 remain.
  • the pins 11, 12 designed as coupling and closure elements are inserted into these openings 17, 18, so that they close the openings 17, 18 and the escape of any corrugation agent that may be used is avoided at the longitudinal ends 15 and 16.
  • the pins 11, 12 are formed simultaneously and in one operation during the injection molding of the tensioning strap 13 according to FIG , 12 are to be locked in the holes 17, 18 and how the holes 17, 18 are closed.
  • the holes 5, 7 of the tensioning straps 2, 3 are also injected during the injection molding of the strap.
  • the tensioning strap according to the invention is to be produced from a permanently elastic plastic which is chemically neutral with respect to the corrugating agent to be used and can be stretched with relatively little force. Tests have shown that the permanent thermoplastic polyurethane "elastomer" supplied by Elastogran GmbH, Lemförde, under the trade name “Elastollan” fulfills the requirements particularly well. This is the above-mentioned thermoplastic rubber-elastic polyurethane.
