Definitions

  • the invention relates to a two-chamber pressure can for dispensing a filling material with a pressure-resistant outer container, with an inner container made of deformable metallic material for receiving the filling material, which is fastened to a lid receiving the dispensing valve and closing the outer container, and with a closable opening on the bottom of the outer container for filling the propellant.
  • Two-chamber pressure cans in which the blowing agent is separated from the filling material, are increasingly being manufactured. They are used, for example, as dispensers for liquid filling goods, as cream dispensers, as dispensers for foods in pasty form or the like. They often use compressed gases that do not pollute the environment, such as C0 2 , N 2 0, N 2 or air. Since, according to the provisions of the law on measurement and calibration, the space which holds the pressurized propellant may not exceed 40% of the volume of the outer container, but on the other hand it must be ensured that the propellant pressure is sufficiently high to largely empty the inner container To be able to drive out the last rest of the contents, high initial pressures of over 10 bar are required for the blowing agent. These very high pressures lead to considerable sealing problems, since the propellant pressure of the full can must not drop even over a long period of time, because otherwise the contents cannot be driven out or cannot be driven out completely.
  • the outer container is designed as a conventional three-part can, the jacket of which is formed from a flat sheet metal cut into a cylinder, which is followed by the overlapping areas are welded together. The ends of this cylindrical jacket are then bulged outwards and flanged together with a corresponding cover and a corresponding base part.
  • the double longitudinal seam there are sealing problems when the inner container is crimped between the jacket and the cover, in particular when an inner container made of metal is used, since there is a discontinuous transition in the region of the flanged seam.
  • the invention has for its object to provide a two-chamber pressure can of the type mentioned, which remains simple with simple manufacture.
  • the outer container is preferably narrowed slightly in the region of its open end, and / or the inner container is slightly expanded in the region of its open end, which on the one hand results in a limited contact area between the outer container and the inner container, while at the same time in the further region lying towards the bottom an annular space for the propellant is created.
  • the inner container can expediently be made of aluminum which has been softened by annealing.
  • the jacket of the outer container can advantageously consist of one piece together with the base.
  • Such a container is particularly easy to manufacture by extrusion. It is also particularly easy to paint and print all around.
  • 10 denotes the outer container, which can consist of one piece with the curved bottom 12.
  • a cup-shaped body can be produced in a known manner by extrusion.
  • An opening is provided in the bottom 12 through which the propellant is later introduced. This opening is closed with a plug 21 after the propellant has been filled in.
  • the outer container can be narrowed at 14 at its open end.
  • the edge is bent outwards. It serves to receive the upper edge 16 of the inner vessel 11 and the outer edge of the lid 18.
  • the inner vessel 11 consists of soft material, preferably of soft annealed aluminum. It can be somewhat expanded in the area of its upper edge at 15. The edge is also bent outwards.
  • the outer dimension of the inner container 11 is chosen at 15 so that it is on the inner wall of the shell of the outer container 10 is present or is only a very short distance, so that the inner container can be easily inserted through the opening of the outer container in this. Due to the above-mentioned design of the inner container 11 or the outer container 10, an annular space 22 is formed after the inner container has been inserted, which serves to receive the propellant. In addition, the inner container can be inserted particularly easily into the outer container.
  • annular layer 17 is arranged, which is made of any suitable sealant, such as e.g. Latex. This layer can e.g. be sprayed on.
  • This sealant layer 17 results in an additional seal between the inner container and the outer container, which is connected upstream of the seal between the inner container and the outer container caused by the usual sealant layer in the edge of the lid. This ensures a very secure seal even over long periods of time.
  • the two-chamber can according to the invention is produced as follows.
  • the bottom of the outer container 10 is produced in a known manner by extrusion, and the free edge is slightly drawn in and bent outwards, as shown in FIG. 2.
  • the hole is then made in the domed bottom 12 and the sealant layer 17 is applied.
  • the thin-walled inner container 11 can be produced in a similar manner by extrusion. It is then further treated in a known manner, in particular soft annealed. An inner protective layer can then be applied, which protects the container from a possibly aggressive filling material. Then the upper part can be expanded a little. It is then turned outside.
  • the inner container 11 is inserted into the outer container 10.
  • the sealant layer 17 is pushed back somewhat.
  • it lies in front of the gap between the inner container and the outer container.
  • the lid is put on, the edge of which also contains a sealant layer in the usual way.
  • the edge of the lid is flanged together with the edges of the outer container 10 and inner container 11, whereby a fixed connection. binding of the parts is produced.
  • the inner container 11 can be filled with filling material through the valve opening in the lid 18, whereupon the valve 19 is fastened to the lid 18 with a valve plate 20 and the inner container is thus closed.
  • the space 22 between the inner container and the outer container is filled with propellant through the opening in the base 12, whereupon this opening is closed with a stopper 21.
  • the propellant acts on the sealant layer 17 lying in front of the gap between the inner container and the outer container in the manner described, and presses the part in front of it against this gap, as a result of which an effective additional sealing It seal is achieved. This results in a very effective seal that prevents the blowing agent from escaping for a long time, even at high propellant pressures.
