Definitions

  • the invention relates to a discharge element for a two-component cartridge.
  • Two-component cartridges for example for a two-component adhesive, a two-component mortar or the like, have within a cartridge two separate receiving spaces for each one component.
  • such cartridges are formed as cylindrical housing.
  • a discharge element usually referred to as a mixer, placed on the neck.
  • a passageway with a mixing device is arranged, with the aid of which the two components are mixed together so that they are expressed from the outlet end of the mixer as homogeneous as possible mixture.
  • the cartridge After use, the cartridge is usually not empty yet. Then the Austragselement is removed and the front end of the neck closed with a cap, so that the content is not dry out.
  • a discharge element is provided which can be placed on the neck of the two-component cartridge. Between the two outlet openings of the cartridge, a web is present, which prevents a simultaneous stripping of both outlet openings ( CA 2562451 A1 ).
  • CA 2562451 A1 discloses all features of the preamble of claim 1.
  • an attachment leading to a common mixing chamber and separate from this a discharge nozzle is provided.
  • the discharge nozzle can be removed from the attachment ( DE 35 01 331 A1 ).
  • a nozzle for a one-component cartridge has contact surfaces for bearing against the edges of a joint ( DE 201 12 737 U1 ).
  • a further discharge element for a one-component cartridge has lateral stabilization surfaces with the aid of which an exact alignment of the axis of the discharge element with respect to a wall surface is to be ensured ( GB 2469868 A ).
  • the invention is based on the object, the user a way to facilitate the removal of component material swollen from the discharge openings.
  • the invention proposes a Austragselement with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
  • the wiping edge of the wiper has a shape corresponding to the shape of the front end of the neck of the two-component cartridge. If the front end, in which the outlet openings of the cartridge end, is flat, then the wiping edge is rectilinear.
  • the stripping device is formed with the scraping edge laterally on the discharge element, wherein it can be provided in particular that the stripping edge runs parallel or approximately parallel to a longitudinal axis of the discharge element.
  • the Austragsieri are usually long, on the one hand to get to difficult places and on the other hand to provide a long mixing distance for the two components. The side is therefore given sufficient space on such a discharge element to attach the stripping.
  • the stripping device is formed adjacent to the connection for the neck of the two-component cartridge.
  • the stripping device can have a side edge in order to also clean the radial outside of the neck of the cartridge. According to the invention, it can be provided that a shoulder provided on the connection of the discharge element forms this side edge.
  • the wiping edge of the wiper device is formed on a rib of the discharge element.
  • an outlet opening for a component is arranged centrally and has a circular opening cross-section.
  • the opening for the second component may be a slot opening surrounding this central opening, or one or more exit openings may be present radially outside the central opening.
  • the stripping device has a pin for this central outlet opening, in which case the stripping edge then adjoins the pin laterally.
  • the Austragselement is inserted with its pin in the central opening and twisted around this pin or the central opening around. This allows the material of the outer openings very easily strip or scrape.
  • the discharge element serves as a handle. Because of the large length of the discharge element, it can be handled favorably for this purpose made possible by the invention.
  • the Austragselement according to the invention can be both for a Form screw as well as for a bayonet connection of a two-component cartridge.
  • connection can be designed as a connecting sleeve, which can also serve to attack for screwing on or for the production of the bayonet connection to the discharge element.
  • the discharge element is a plastic part, in particular a one-piece plastic part.
  • the invention also relates to the use of such a discharge element for stripping material that has swelled out of the discharge openings of a two-component cartridge.
  • the dispensing element is removed from the two-component cartridge and then the scraper edge is moved over the outlet opening of the cartridge.
  • the material that projects beyond the plane of the opening can be stripped off.
  • the discharge opening can be closed with the lid provided for this purpose.
  • FIG. 1 shows very simplified the discharge end of a two-component cartridge.
  • the two-component cartridge has an outer housing 1, which is formed substantially cylindrical. At one end, that in FIG. 1 can be seen, a neck 2 is attached to the housing, which is cylindrical. It ends in a front end 3, which lies in the example shown in a plane.
  • a second inner housing 4 is arranged, which is geometrically similar and at its in FIG. 1 upper end forms a channel 5.
  • This channel 5 is formed by a sleeve 6 which is arranged concentrically to the neck 2.
  • the correct position of the inner housing 4 and its sleeve 6 is ensured by webs, not shown.
  • the sleeve 6 forms at the outer end of the channel 5 a central discharge opening 7 for the material, which is arranged in the inner housing 4.
  • the arranged in the space between the housing 1 and the inner housing 4 material exits through the annular gap 8 between the neck 2 and the sleeve 6 from the front end 3.
  • This slot-like outlet opening 9 thus forms the outlet opening for the second component.
  • FIG. 1 For pressing the material out of the cartridge, pistons are used FIG. 1 are not shown.
  • the neck 2 On its outside, the neck 2 has a thread 10. This thread 10 starts at an axial distance from the front end 3 of the neck 2.
  • a discharge element 11 is screwed on the neck 2, when the cartridge is to be used.
  • This Austragselement is in side view in FIG. 2 shown. It contains at his in FIG. 1 lower end a connection 12 in the form of a connection sleeve 13.
  • This connection sleeve 13 has on its inner side a thread which corresponds to the thread 10 on the outside of the neck 2.
  • Austragselement extends in the external view of the Austragselements course invisible passage to the in FIG. 2 Discharge end 14 shown above. Within this passage, the two components are mixed together.
  • a circumferential shoulder 15 is formed Immediately behind the connecting sleeve 13, the outer diameter of the discharge element 11 decreases, so that there is a circumferential shoulder 15 is formed.
  • This shoulder 15 extends perpendicular to the longitudinal axis of the discharge element 11.
  • a rib 16 is formed directly following the shoulder 15.
  • This rib has a flat outer side 17, so that in each case an edge 18 is formed between the sides of the rib 16 and its outer side 17.
  • a cylindrical pin 19 is formed, which is perpendicular to the outer side 17.
  • the wiping edge 18 forms a stripping device 20, wherein in the illustrated embodiment two such stripping devices 20 are formed on the discharge element 11.
  • the stripping device is the shoulder 15 of the connecting sleeve 13 is limited by a further shoulder 21 opposite.
  • This shoulder 21 also extends perpendicular to the longitudinal axis of the discharge element, while the ribs 16 and the scraping edges 18 extend parallel to the longitudinal axis.
  • the discharge element 11 is with its connection 12 to the neck 2 of the Cartridge adapted. Accordingly, the stripping device 20 is adapted to the neck 2 of the cartridge or in other words to the terminal 12 of the discharge element 11.
  • FIG. 3 The manner of using the scraper 20 is shown schematically in FIG. 3 shown.
  • the discharge element 11 is unscrewed from the neck 2 of the cartridge, tilted by 90 °, and inserted with the pin 19 in the outlet opening 7 of the channel 5.
  • This pin 19 now serves as a support for a rotational movement of the discharge element 11.
  • the edges formed by the shoulders 15 and 21 are now just outside the radial outer side of the neck 2 in the area in which no thread 10 is present.
  • the material present at the opening 9 is scraped off by means of the edges 18. If this material has already hardened slightly, a large lever arm is available due to the large length of the discharge element 11.
  • FIG. 4 simplifies a modified embodiment.
  • a shoulder 15 is present, which forms a side edge.
  • a half turn is sufficient to once turn off the material on the radially outer side of the neck 2 is in the embodiment of the FIG. 4 a full turn required.
  • the wiping edge is present only on one side of the pin 18.
