Definitions

  • the invention relates to a cartridge with ventable piston.
  • the air bubbles in the cartridge arise when the piston is filled in the cartridge opening is used. Since the pistons have a sealing function to the cartridge wall must, at least partially with the air cushion located between product and piston locked in.
  • Another problem for some products is the escape of ingredients or penetration moisture or other air components.
  • a piston with a resilient bottom is mentioned in DE 42 29 588, the rear edge because of its larger diameter rests on the edge of the cartridge.
  • a cartridge for receiving pasty to meet these requirements Materials presented with ventable piston, the piston from a piston part and a lid part is made, in which after the vent, the cover part of the vent path permanently closes.
  • the piston part is usually close to the inner wall of the cylindrical cartridge hollow body at. It is provided with a vent channel, which preferably has an axially located in the middle Channel is.
  • the piston part is closed by a lid part facing the pasty mass added to a flask.
  • the cover part is preferably convex on the side facing the pasty mass.
  • the vent opening (s) preferably form an annular opening in the region of the inner wall the cylindrical hollow body of the cartridge.
  • the piston cover is preferably longitudinally axial stored in the direction of the piston part movable on the piston part, in such a way that in the closing process, the air between the piston and pasty material in the region of Cartridge inner wall through the annular vent between the piston part and cover part enters the piston part and discharged through a hole in the middle of the piston part becomes.
  • venting the piston part is in this embodiment by the contact pressure the pasty mass pushed in the direction of the lid part.
  • a latching mechanism ensures that when handling the piston at a later time in the filled state of the cartridges cover part and piston part can not solve each other.
  • This latching mechanism is preferably located in near the axially centered venting channel.
  • piston and cover part e.g. through a screw or bayonet mechanism connected, which also for permanent closure of the ventilation duct leads, however, by a movement from the outside.
  • a retaining mechanism holds the open arrangement between piston part and Cover part, so that the lid part in the open state does not completely detach from the piston part can. It may also be advantageous if a sealing ring of rubber-elastic material between the piston part and the cover part around the opening of the axially centered ventilation channel is attached.
  • the sealing ring should be sized so that it is compressed when to move lid and piston part towards each other. After the latching or the permanent Assembly of piston and cover part, the ring remains compressed and In addition, the access to the ventilation channel is sealed off.
  • the invention relates in its most general form to a cartridge for receiving pasty material with a ventable piston, wherein the piston consists of a piston part 2 and a cover part 3 , in which after the venting the cover part closes the venting path (4/5) ,
  • the preferred embodiment of the invention thus relates to a cartridge for receiving pasty material 6 with a cylindrical cartridge hollow body 1 with ventable piston from a tight against the inner wall of the hollow body 1 piston part 2 with vent channel 5 and a pasty mass 6 facing lid part 3 , for the Inserting closable vent opening (s) 4 leaves free, which allow the venting through the vent passage 5 .
  • the unit of piston 2 with the preassembled cover 3 used after filling.
  • the lid is convex on the product side. The air is thereby forced to the edge of the piston. Annular vents 4 are provided between the lid 3 and the piston 2 at the edge, so that the air enters the space between the piston 2 and cover 3 and exits through the opening 5 in the middle.
  • a locking mechanism 7 is provided, which ensures that when handling the piston 2/3 at a later time in the filled state, the lid 3 and 2 piston can not be separated from each other.
  • the locking mechanism 7 can be seen in Fig. 2.
  • the lid 3 engages in the center of the piston 2 a.
  • Another locking mechanism may be provided in the region of the product parts appearing T-shaped in section on the edge, which would give the cover 3 further support.
  • a holder 9 is shown in Fig. 3, which ensures that the piston part and the cover part in the open state can not completely remove from each other.
  • sealing ring 8 made of rubber-elastic material, which is compressed by the contact pressure during latching and the access to the vent opening 5 additionally seals tight.
