Definitions

  • the invention relates to a method for producing a two-chamber pressure pack with an outer body, which encloses a pressurizable interior and forms an opening through which an inner body made of fold-forming or crushable material is used.
  • Such two-chamber pressure packs are generally used today as a replacement for the known pressure containers with propellant gas.
  • the medium is discharged from the inner body by pressurizing the interior of the outer body.
  • the medium to be dispensed therefore does not come into contact with this pressure medium, but is expressed by changing the inner body through a valve.
  • These known two-chamber pressure packs consist essentially of three parts, namely the outer body, for example an aluminum sleeve with a bottom, the inner body, for example a very thin aluminum sleeve and a funnel, which is placed on the mouth edge of the inner and outer body and surrounds it in a sealing manner. The corresponding valve is then inserted in the center of this disk-shaped funnel.
  • Attaching the funnel to the mouth edges of the inner and outer body means a considerable amount of work, since this has to be done by hand.
  • the funnel is rolled or flanged together with the mouth edges. That is why he needs a certain place. Since the valve itself usually also requires a diameter of 25 mm, the openings of today's two-chamber pressure packs must have a total diameter of around 40-65 mm. In between, only two-chamber pressure packs with graduated dimensions are used.
  • the inventor has set itself the goal of developing a method of the type mentioned above, by means of which the attachment of the additional funnel becomes superfluous, in which the interior of the outer body can be kept absolutely tight and in which two-chamber pressure packs with different opening diameters from 1 Customs, d. H. can be produced from 25.4 mm.
  • the outer body and inner body are connected to one another in a predetermined area before flanging or the like.
  • connection is preferably made by welding, gluing, shaping or the like.
  • a coating has proven to be the best here, which is applied either to the outer body or to the inner body or to both in the connection region before the inner body is inserted into the outer body.
  • This coating for example a suitable adhesive, can then dry so that the inner body is inserted into the outer body without changing the coating.
  • the two-chamber pressure pack preferably passes through an oven in which the coating is liquefied. This already creates a certain connection between the inner body and the outer body.
  • the inner body since the inner body generally maintains a certain distance from the outer body in order to be surrounded by sufficient pressure medium in the position of use, it has proven to be advisable to insert a tool into the opening of the two-chamber pressure pack, via which the inner body in the corresponding connection area is pressed against the outer body.
  • This tool can be heated so that the coating is liquefied or kept in motion by this heat.
  • the mouth edges are then flanged, this preferably being done by rolling.
  • the two-chamber pressure pack now only needs to be filled with the medium to be dispensed and the valve put on, through which the space of the inner body is now sealed, and the propellant gas has to be supplied via a bottom hole.
  • This method according to the invention also has the advantage that both the outer body and the inner body can be printed, varnished or the like before the flanging.
  • all standard interior protective lacquers can be used.
  • the flanging can be done by means of an automatic machine, so that considerable labor is saved.
  • a two-chamber pressure pack P has a sleeve-shaped outer body 1, which in the present exemplary embodiment essentially consists of a cylinder jacket 2 and a base cover 3.
  • This outer body 1 can, for example, be produced from an aluminum blank in the extrusion or deep-drawing process.
  • the bottom cover 3 has a bore 4 through which the interior I can be pressurized. After this process, the bore 4 can be closed.
  • An inner body 6 is inserted into a cylinder opening 5 beyond the bottom cover 3 of the outer body 1.
  • This inner body 6 also has a cylinder jacket 7 and a closed bottom cover 8.
  • this inner body 6 consists of a relatively thin aluminum, so that it can be crushed with the formation of folds.
  • Cylinder jacket 7 and base cover 8 enclose a space R, which in the position of use serves to receive a medium to be dispensed.
  • the inner body 6 maintains a distance a from the cylinder jacket 2 of the outer body 1 over long distances.
  • inner body 6 or its cylinder jacket 7 is connected to cylinder jacket 2 in area b.
  • the connection is made, for example, by welding, gluing, laser welding, shaping or the like.
  • This preliminary stage of a two-chamber pressure pack according to the invention is produced as follows:
  • the outer body 1 is drawn from an aluminum blank.
  • the hole 4 is made in the bottom cover 3 and the cylinder jacket 2 is covered or welded with a coating 9 of an adhesive over the region b.
  • the inner body 6 is inserted, the coating 9 being solidified so that it does not hinder insertion.
  • the two-chamber pressure pack P now passes through an oven in which the coating 9 is liquefied. As a result, a connection between cylinder jacket 2 and cylinder jacket 7 is already initiated. However, the correct connection produces a heated tool which is inserted through the cylinder opening 5 and presses the cylinder jacket 7 in region b against the cylinder jacket 2.
  • the next processing stage is shown in FIG. 2.
  • the bottom cover 3 is deformed so that it can withstand an internal pressure in the interior I and does not bulge.
  • cylinder jacket 2 and cylinder jacket 7 are flanged outwards in the region of the cylinder opening 5, so that a flanged edge 10 is created.
  • cylinder jacket 2 and cylinder jacket 7 are simultaneously pulled inwards in a specific area.
  • the space R of the inner body 6 is now filled with the substance to be dispensed and the cylinder opening 5 is closed by a cover with a valve, not shown. This lid seals the flange 10.
  • the interior I of the outer body 1 is then pressurized through the bore 4, the bore 4 then being closed.
  • the inner body 6 is pressurized, so that when the valve is actuated, the medium is discharged from the space R of the inner body 6 through the valve, while the inner body 6 yields to the same extent to the pressure in the interior of the outer body 1 and crumples .
