Definitions

  • the present invention relates to a storage container according to the preamble of claim 1, a setting device according to the preamble of claim 10 and a method for producing a storage container according to the preamble of claim 11.
  • Combustion-powered setting devices have a combustion chamber with an ignition device.
  • Setting elements eg. As nails or bolts are introduced with a setting tool in a setting object.
  • a generally liquid fuel is introduced, so that within the combustion chamber, a mixture of air and gaseous fuel is present.
  • the fuel is stored in a storage container under pressure as a liquid and due to the lower pressure in the combustion chamber, the fuel changes its state of aggregation into the gaseous state of matter. For a precise metering of the amount of fuel, it is necessary that this is supplied as a liquid of the combustion chamber.
  • combustion power driven setting tools generally include a solenoid valve as a timed metering device or a mechanical valve as a volume controlled metering device.
  • the storage container is divided into two separate chambers, namely in an interior and an exterior space.
  • the fuel is arranged in liquid form and the outside space is with an outside gas filled. Due to the pressure of the outside gas in the exterior space, the fuel in the interior never gets below the vapor pressure of the fuel, so that the fuel in the interior is always in the liquid state.
  • the outer gas has a higher vapor pressure than the inner gas, so that even when discharging fuel in liquid form from the interior and a consequent reduction in the volume of the interior and an increase in the volume of the outer space in the interior of the fuel continues is present in the liquid state of matter as a liquid.
  • the interior space is separated from the exterior space by a bag.
  • a container wall bounds a total interior of the storage container and by means of the bag, the total interior space is divided into the interior and the exterior space as two separate chambers.
  • the bag is constructed of a flexible sheet material as a composite sheet material.
  • a first film material and a second film material are welded together in a material-locking manner at a connection region.

  • the first and second film material are welded to one another by means of the plastic, so that between the film of metal of the first film material and the metal foil of the second foil material part there are at least two plastic foils of the first and second foil material part welded together.
  • the foil made of metal, in particular of aluminum, serves as a permeation barrier.
  • fuel can flow from the interior space into the exterior space through the films of plastic welded together, and conversely external gas can migrate from the exterior space into the interior space.
  • the plastic of the plastic films does not form a sufficient permeation barrier. This migration or permeation of fuel and outer gas causes the vapor pressure on the fuel and the outer gas to change such that the ability of the outer gas, the fuel to keep fluid, greatly reduced.
  • the storage container can thus be stored, especially in the arrangement of the setting tool, only for a short time, since the permanent permeation of fuel into the outer space and of external gas into the interior causes the fuel in the interior of the storage container at least partially Gas is present and thus can not be dosed sufficiently accurate in the combustion chamber of the setting tool.
  • can-in-can systems of the storage container.
  • a deformable aluminum can is arranged within the outer container wall.
  • the aluminum can prevents permeation, however, these can-in-can systems are particularly expensive to manufacture and are therefore generally too expensive for use in setting tools.
  • the EP 1 532 057 B1 shows a dispensing valve with bags for the delivery of pressurized liquids, foams, gels or the like with a welded bag of flexible film material with a welded receiving body, which is placed through a closable with a valve cover opening of a container therein, wherein the valve cover receives a valve body with a valve needle axially displaceable against the action of an elastic element out of a closed position.

  • the first and second film material part 19, 20 each having a thickness 29 (FIG. Fig. 3 ) to provide. This is done, for example, in that the composite film 30 is unwound from a roll and then correspondingly large parts for the first and second film material part 19, 20 are cut off. Subsequently, the two foil material parts 19, 20 are stacked, so that thereby the end and edge region also lies on top of each other.
  • the first and second film material parts 19, 20 are heated at this end or edge region, and then a compressive force is applied to this edge region of the first and second film material parts 19, 20, thereby producing in each case the second and third films 33, 34 made of plastic of the first and second film material part 19, 20 squeezed or pressed between the two sheets 31 of metal.
  • a welded connection 23 is produced as a metal connection 22 between these two foils 31 made of metal, in that the two foils 31 made of metal are welded directly to one another at the connection region 21 ( Fig. 4 ).
  • the connecting region 21 Between the two foils 31 made of metal thus exclusively metal is arranged on the connecting region 21, so that a permeation of fuel 17 from the interior 15 into the outer space 16 and vice versa of outer gas 18 from the outer space 16 in the interior 15 is substantially excluded.
  • the first film 32 made of plastic, respectively. Notwithstanding this, when the plastic is pressed out prior to the production of the metal connection 22, the first film 32 on the connection region 31 can also be removed (not shown).
  • the width 35 of the Connecting portion 21, namely the welded joint 23 is substantially greater than the sum of the thicknesses 29 of the first and second sheet material part 19, 20.
  • a plastic weld 38 between the second and third plastic film 33, 34 of the first Film material part 19 and the second and third films 33, 34 made of plastic of the second film material part 20.
  • the plastic weld joint 38 does not prevent the permeation of fuel 17 into the outer space 16 and from outer gas 18 into the inner space 15 because the plastic does not form a permeation barrier.
  • the thickness 37 of the metal connection 22 is substantially smaller than the thickness 39 of the plastic weld joint 38 and substantially smaller than the sum of the thicknesses of the first and second sheet material parts 19, 20.
  • the width 35 of the entire connection region 21 is shown, ie the metal connection 22 and the plastic weld connection 38.
  • Fig. 4 only the width 35 of the metal connection 22 is shown.
  • Fig. 5 is a part of the storage container 10 in a second embodiment, namely substantially the connecting portion 21 of the bag 7 of the storage container 10, shown.
  • the first and second foil material part 19, 20 comprises only the foil 31 made of metal.
  • the two films 31 made of metal are connected to one another in a materially bonded manner by means of a solder connection 24, so that a solder layer 36 is thereby arranged between the two films 31.
  • the solder layer 36 is formed of metal, so that between the two sheets 31 of metal of the first and second sheet material part 19, 20 is formed exclusively metal, but the metal of the solder layer 36 is a different metal than the metal of the foils 31 made of metal.
  • Fig. 6 is a part of the storage container 10 in a third embodiment, namely substantially the connecting portion 21 of the bag 7 of the storage container 10, shown.
  • the two plastic films 34 but not the two plastic films 33, have been squeezed out of the connection region 21, so that the film thickness of the plastic film formed from the films 33, 34 in the connection region 21 is reduced by approximately 75%.
  • the two plastic films 33 are connected to one another by means of a plastic welding connection 23. In non-illustrated embodiments, the plastic films are glued together.
  • the bag 7 is produced on the connection region 21 with a metal connection 22, so that exclusively metal is formed between the two film material parts 19, 20, each with the foil 31 of metal between the two films 31 on the metal connection 22, or these are directly connected to each other, so that there is no plastic on the metal connection 22, which would allow permeation.
  • the bag 7 can be easily manufactured, so that advantageously on the one hand the storage container 10 is inexpensive to manufacture and on the other hand, the permeation between the interior 15 and the outer space 16 and vice versa is substantially excluded at the metal compound 22.
