  • the dispensing member includes elastic walls of polymeric material enclosing an elongate container for holding a reservoir of the rust converter, and a dispensing tip of polymeric material having a housing attached to the reservoir having a passage communicating with an opening leading into the reservoir stands.
  • a valve member in the housing may be tight with its periphery to an inner surface of the same, the one end of the passage forms, with a tip through the outlet end of the passage, when the valve member is close to this inner surface.

  • the fixation can also be done for example in the form of a press fit or a catch.
  • the receiving unit 13 and the closure unit 3 may be made of plastic or a metallic material.
  • the reservoir 1 is in this embodiment made of a first material, for example a soft polyethylene (for example LDPE low density polyethylene) - or has such.
  • the receiving unit 13 is preferably made of a second material - for example, a harder polymer, but in any case a relative to the first material of the reservoir harder material or has such.
  • the light-curing material is conveyed or pressed into the output device A.
  • the light-curing material enters the closure unit 3 and is conveyed through this by a schematically indicated by dashed dosing 5 through the outlet opening 3.1.
  • the LED lamp 9 can be operated so that the output light-curing material is immediately cured. Turning over the applicator 100 to cure the output light-curing adhesive / material can be dispensed with.
  • the photocurable composite is cured by light, in this embodiment by LED light in the wavelength range between 395 and 470 nanometers (nm). This LED light is provided by the integrated into the snap device LED lamp 7, which can be detachably or permanently attached to the reservoir 1.
  • the reservoir 1 is shown, which has a peripheral Aufsteckvorkung 11, to which a snap device 7 (s. Fig. 1 and 6 ) can be clipped with LED lamp 9 integrated in an LED housing 9.1.
  • the reservoir 1 has at one end an opening 1.1 through which exits the light-curing material at peripheral pressure on the reservoir 1 in the output device, not shown here.

  • an internal thread 3.3 is formed with locking elements, not shown, which is screwed onto the external thread 13.4 and then inextricably locked, wherein the closure unit 3 is still rotatable and corresponding to the pitch of the thread in the longitudinal direction.
  • the non-designated inner diameter of the discharge opening 3.1 substantially corresponds to the outer diameter of the massive tip 13.3 of in FIG. 3
  • In the assembled state engages in the closed output device A in accordance with the left illustration in FIG. 16 the massive tip 13.3 in the outlet opening 3.1, whereby it is closed and no material can be output.
  • FIG. 17 the snap device 7 is shown with the LED 9 and the LED housing 9.1. This is in accordance with the slip-on preparation 11 FIG. 13 attachable.

  • a switch preferably a pressure switch 23 for actuating the LED 9 is present.
  • the reservoir 1 the output device A, consisting of receiving unit 13 and closure unit 3, respectively.
  • the closure unit 3 is formed in the manner of a rotary closure and has an outlet opening 3.1, which is closed in the closed state by the massive tip 13.3 of the receiving unit ( FIGS. 19 and 20 ) and is released in the open state after rotation of the closure unit 3 by the massive tip 3 ( Fig. 18 ) so that the curable material can escape when the reservoir 1 is compressed by manual operation.
  • the closure unit 3 is therefore made of a corresponding opaque plastic or material (eg of metallic material), which prevents the light of the LED lamp 9 from curing the light-curing material before it leaves the outlet opening 3.1.
  • the LED housing 9.1 with the receiving unit 13 in one piece, for example by injection molding, formed.
  • the closure unit 3 is open. If pressure is exerted on the wall of the reservoir 1, as indicated by the bold arrows, the light-curing material contained therein is conveyed through the opening 1.1 of the reservoir 1 into the receiving unit 13 and the closure unit 3 and can exit through the outlet opening 3.1 (see FIG.
  • FIG. 19 shows a gap between the massive tip 13.3 and the outlet opening 3.1. It is according to FIG. 19 also possible to form the LED housing 9.1 to the wall of the reservoir 1 or thus integrally formed or clipped. Another variant shows FIG. 20 , In this, the LED housing 9.1 is arranged in the region of the closure unit 3 or integrally formed therewith.
  • a filling opening can be provided in the wall of the reservoir 1. This may be provided at the opposite end of the dispenser A and is according to FIG. 20 closed for example with a detachable end cap 1.3.
  • the LED lamp 9 with the LED housing 9.1 can also be arranged between output device A and reservoir 1 (for example by a clamping connection), in which case a corresponding material flow has to be ensured.
  • the LED housing 9.1 fastened by a snap connection at least partially surrounds the reservoir 1 and the receiving unit A with the snap device and thus prevents the receiving unit A from inadvertently loosening when it is screwed to the reservoir 1.
  • the LED lamp of the applicator can also be screwed by a screw connection to the reservoir or to the output device.
  • One or more LEDs are preferably used which generate light in the visible wavelength range. Blue light in the wavelength range from 420 to 490 nm has proved to be particularly advantageous. A big advantage is that the light in the visible wavelength range is harmless to health.
