  • the acting pressure does not move the container 313 together with the repair nozzle 100 due to the support, but moves the propulsion element within the container 313 so that the material 315 to be dispensed is squeezed out of the container 313, enters the product channel of the repair nozzle 100 and finally over the slit-shaped Orifice 103 can be issued.
  • FIG. 6 shows a detailed view C of the repair system FIG. 5 ,
  • the repair nozzle 100 is mounted on the container 313 containing the material 315 to be dispensed.
  • the internal thread 114 of the repair nozzle 100 has been brought into engagement with a corresponding external thread 314 of the container.
  • the sealing lip ring 109 of the repair nozzle 100 adjoins an end region 316 of the container 313.
  • a rotation of the two threaded portions 114, 314 to each other such that the sealing lip ring 109 is partially pressed into the end portion 316 of the container 313 and / or cuts to a secure seal, even with production-related surface inaccuracies on the end portion 316th to be able to guarantee.
  • the sealing lip ring 109 can be configured to be flexible, for example, and be adapted to the end region 316 of the container by being screwed onto the external thread 314, so that, for example, a deformation of the sealing lip ring 109 results in a sealing function without being cut into the end region 316.
  • the repair nozzle 100 is sealed to the container 313 via two sealing elements. On the one hand via the threaded portions 114, 314 by providing a high-precision internal thread 114 of the repair nozzle, whereby a sealing region 115 is provided, on the other hand on the protruding sealing lip ring 109, which allows a sealing possibility at the end portion 316 of the cartridge 313.
  • FIG. 7 shows an alternative embodiment of a repair nozzle 200 having a proximal product delivery side 201 and a distal product delivery side 202 and with a product channel 205.
  • the product channel 205 connects a product delivery port 216 on the proximal product delivery side 201 to a slit-shaped port 203 on the product output distal side 202 is designed in the proximal region of the repair nozzle 200 substantially rotationally symmetrical about an axis of rotation 206 and is enclosed in the direction of the distal product discharge side 202 by a trapezoidal jacket portion 204 having the slot-shaped mouth opening 203.
  • the trapezoidal cladding region 204 is configured such that a base 208 is disposed on the product output distal side 202.
  • the slot-shaped mouth opening 203 extends over the base 208 of the trapezoidal shell portion 204.
  • a radially outwardly with respect to the axis of rotation 206 projecting collar 207 is provided which serves to support the repair nozzle 200 to a container.
  • the trapezoidal jacket region 204 has on the surface a plurality of separation aids 214 arranged parallel to the base 208. These separation aids 214 represent markings at which the user can sever parts of the trapezoidal jacket region 204. Due to the trapezoidal shape of the shell portion 204, severing a part at the distal product discharge side 202 is accompanied by a reduction in the base 208.
  • the slit-shaped orifice 203 which extends across the base 208, is also reduced in size.
  • the user can in this way by separating parts of the trapezoidal shell portion 204 vary the size of the slit-shaped orifice opening 203 to adjust this to the dispensed material or the size of the desired bead of material.
  • the cladding region 204 has reinforcing ribs, not shown, and is provided on the side of the proximal Artszu fertilseite 201 with an internal thread 211, with which the repair nozzle 200 can be mounted on a container with a corresponding external thread.
  • the internal thread 211 is a precision thread described above which provides a first sealing element via a sealing region 212.
  • a sealing lip ring 209 is provided as a further sealing element in the region of the proximal Artszu slaughter 201. This encloses annularly the product feed opening 216 and extends in the proximal direction. Due to the proximal extension, the sealing lip ring 209 protrudes in the direction of the container when the repair nozzle 200 is fastened on a container.
  • the extent of the sealing lip ring 209 is designed such that it comes into contact with the attachment of the repair nozzle 200 with the container and thus causes a seal between the repair nozzle 200 and container.
  • the repair nozzle 200 has only one of the sealing elements described.
