Definitions

  • the invention relates to a closure for a with a screw socket Pouring hole provided toner bottle, the one screwed onto the screw neck Has a toner bottle holder with an annular support flange, wherein the support flange with a passage opening provide the unscrewing movement the toner bottle holder is limited to the screw neck, whereby In the toner bottle holder, a closure slide for opening and closing the passage opening is adjustable and where sealing elements the transitions from the screw socket to the support flange and from Seal the support flange to the slide.
  • annular disk-shaped first sealing element seals the Support flange of the toner bottle holder for the screw neck of the toner bottle down.
  • the first sealing element is facing the screw socket Side of the support flange, e.g. glued.
  • the second Sealing element is plate-shaped and is on the support flange Toner bottle receptacle applied to the side of the closure slide facing e.g. glued.
  • the two sealing elements are made of foam material and usually punched out of prefabricated sheets.
  • the closure slide is a simple injection molded part producible and the toner bottle holder can with the sealing elements are produced fully automatically in the two-component injection molding process, whereby on known two-component plastic injection molding machines can be used with two spray stations.
  • the sealing elements can also be connected much more firmly to the toner flange holder, so that loosening need not be feared when the slide lock is opened and closed frequently.
  • the sealing elements can be held on the support flange can be further improved in that the sealing elements in grooves of the support flange are partially sunk.
  • the sealing elements are provided by means of a connecting web covering the passage opening of the support flange combined into a one-piece U-shaped sealing element then the sealing element can also be the passage opening in the support flange include in the seal.
  • the closure slide facing sealing element or the part facing the closing slide of the sealing element is flattened towards the outer circumference, or that the Locking slide with a snug and / or press fit in a receiving chamber Toner bottle holder is guided adjustable.
  • the manufacture of the closure is characterized by a process in which that the toner bottle holder with the sealing elements or the sealing element on a two-component plastic injection molding machine is manufactured with two spray stations.
  • the toner bottle holder with openings in the support flange is made from a first plastic and then in the second injection station, the two sealing elements with released openings in the support flange from one side of the toner bottle holder a second plastic.
  • Both sealing elements or the sealing element can be arranged on areas of the toner bottle holder accessible from different sides Inject from one side, which is the design of the mold halves simplified in the spraying stations.
  • the container e.g. a toner bottle runs in a screw neck 10 External thread.
  • a toner bottle holder is placed on this screw neck 10 20 screwed on, which is a sleeve-shaped screw part 24 with an internal thread having.
  • a closure slide 30 is guided such that it can be seen in FIG. 1 is to cover the passage opening 22 of the support flange 21 selectively or to be able to release.
  • the support flange 21 of the toner bottle holder 20 covers the end face 11 of the screw neck 10 of the toner bottle.
  • the difficulties with one such a closure prepares the seal between the screw connector 10 the toner bottle and the toner bottle holder 20 and between the toner bottle holder 20 and the closure slider 30, since the content of the toner bottle is thinner than water.
  • the sealing elements for these transitions must be firmly attached because their connecting surfaces when screwing the toner bottle holder 20 on the screw neck 10 and be adjusted to shear when adjusting the closure slide 30.
  • sealing elements 41 and 42 injection molded, which are fixed connected to the support flange 21.
  • the support flange 21 can be molded Have grooves 22 so that the sealing elements 41 and 42 with Parts 43 are partially sunk in the grooves 22.
  • the sealing elements 41 and 42 held even better in the radial direction. This is especially important when adjusting the slide slide 30, so that repeated actuation, the sealing element 41 does not come from the support flange 21 is solved.
  • the closure slide 30 supports the sealing element 41 turned away from guide parts 23 of the toner bottle holder 20, see above that it is in the closed position by press fitting over the sealing element 41 is held on the support flange 21.
  • the adjustment of the slide lock 30 from the open position to the closed position is thereby facilitated that the front end of the slide shutter 30 is provided with a ramp 31 and so while compressing the sealing element 41 Passage opening 22 of the support flange 21 can pass without the sealing element 41 to push ahead.
  • the support flange 21 is provided with openings 26 distributed over the circumference, so that the sealing element 42, which the end face 11 of the Seals screw 10 seals, are injected from the same side can.
  • the sealing element 41 faces the fixed tool half and the sealing element 42 is in the movable tool half specified. It is crucial, however, that a prefabricated toner bottle holder first 20 with openings 22 in the support flange 21 made of plastic is manufactured with sufficient stability and then the sealing elements 41 and 42 molded from plastic with the required elasticity become.
  • This manufacturing process can be carried out with appropriately designed tool halves on a two-component injection molding machine with two injection stations run fully automatically, what an inexpensive closure is being used. When the sealing elements 41 and 42 are injected, the fill Breakthroughs 22, as the parts 45 show. The two spray stations provide the required plastics ready.
  • the arrangement of the toner bottle holder 20 in the tool can thus be selected be that the part with the part 24 essentially through the movable tool half is determined so that the prefabricated toner bottle holder 20 can be transported to the second injection station with this mold half, where then only the space for the sealing element 42 has to be released.
  • sealing elements 41 and 42 can also form a sealing element 40 can be summarized.
  • a web 44 connects both sealing elements 41 and 42 to a U-shaped structure that the support flange 21 also covers on the side of the passage opening 22.
  • the jetty 44 then takes over the material flow from the sealing element during injection 41 to the sealing element 42.
  • the support flange 21 can also be used in this one-piece sealing element 40 may be provided with grooves 22.
  • the production can again on a two-component injection molding machine with two Spray stations take place fully automatically.
  • the U-shaped sealing member 40 takes the support flange 21 on three sides and is clearly fixed with this connected, it still covers the passage opening 22.
  • When removed or withdrawn closure slide 30 then becomes the pouring opening 27 released the toner bottle holder 20 and there is a connection from the toner bottle via the passage opening covered by the sealing element 40 22 of the support flange 21 to the pouring opening 27.
