Definitions

  • the invention relates to a container with a removable upper part, which contains a valve for dispensing a liquid or pasty product from a disposable packaging which can be inserted into the container from above and which acts on a pressure generated in the container by a propellant gas.
  • US Pat. No. 3,282,473 discloses a pressure container which can be connected to a propellant gas reservoir and in which, after unscrewing its base plate, there is a tube in a support plate located in the head region of the container can be screwed in. It is emptied using a tilt valve.
  • a tilt valve When the tube is screwed in, pressure is inevitably applied. Since the tube mouth is open . must be part of it. of the product, even before a seal is made between the tube and the valve, and remains in the head part of the pressure vessel. The same thing happens when you unscrew the tube. The result of this are product residues in the container head, which is virtually inaccessible from the outside, which, as a result of hardening, can lead to malfunctions in the tilting valve and can also decompose.
  • a container of the type specified in the introduction is known from US Pat. No. 3,561,644.
  • the disposable packaging consists of a cartridge with a tubular outlet nozzle which is passed through the valve designed as a pinch valve.
  • This cartridge is emptied according to the piston principle using a bellows containing the propellant.
  • This principle cannot be used for single-use packaging in the form of metal or plastic tubes.
  • the replacement of the cartridge proves to be extraordinarily cumbersome, because the container must first be deep-frozen so that the propellant gas can be liquefied again in the bellows and the latter can be returned to the starting position.
  • the invention has for its object to provide a container of the type specified in the introduction, which allows easy emptying and a simple change of any disposable packaging in tube or cartridge form with a simple structure.
  • the disposable packaging has a collar in the region of its emptying opening, by means of which it extends between the upper edge and the upper part of which can be clamped in a pressure-tight manner and that the gas pressure of the propellant gas acts on all sides of the disposable packaging.
  • the collar of the disposable packaging advantageously consists of elastic material and then itself forms the seal between the upper edge of the container and its upper part, which is screwed to the container or connected in some other way in such a way that the pressure required for sealing on the upper edge of the container overlying collar is generated.
  • a seal of suitable shape is provided instead between the upper edge of the container and the underside of the collar, which seal can either be inserted into a flat groove in the upper edge of the container or glued to the underside of the collar.
  • the collar can form the upper end of the disposable packaging and be integrally connected to it, that is, for example, manufactured together with the packaging or sealed or welded onto it as a lid after it has been filled.
  • the collar can also be screwed onto the emptying opening of the disposable packaging, in particular then if the disposable packaging is a commercially available tube, in which case the collar is screwed onto the tube instead of the screw cap.
  • the collar has a passage opening for the product which is closed by an elastic sealing plate, and a hollow needle which is directed towards this passage opening and penetrates the sealing plate when the container upper part is placed is connected to the valve in the upper part of the container.
  • the sealing plate can either be sealed onto the passage opening, preferably from the underside thereof, or can be inserted in the form of a flat plug.
  • the collar itself is made of a material of sufficient elasticity and thickness, it can itself take on the role of the sealing plate.
  • the collar tightly connects a tubular emptying nozzle to the emptying opening of the disposable packaging, the valve then being designed as a pinch valve acting on this emptying nozzle.
  • the emptying spout can optionally be an integral part of the collar or the disposable packaging. But it can also be a separate part that is tightly connected to the mouth of the disposable packaging by screwing the collar.
  • Propellant gas is preferably supplied via a valve in the bottom of the container. This could be done, for example, via a refill bottle, similar to that used to refill gas lighters.
  • valve is part of a chamber of the container that is open at the bottom, small gas storage container and opens under axial pressure on the latter.
  • the valve is a portioning valve screwed into the bottom of the container.
  • the portioning valve ensures that only the amount of propellant gas required for completely emptying a disposable packaging passes into the container, regardless of the position of the gas storage container when the portioning valve is actuated and how long the actuation takes place.
  • liquid propellant gas can escape, which in the present case would lead to an excess in the container which would escape unused when the disposable packaging was changed.
  • Figure 1 shows the container during the insertion of a tube 1, to which a collar 2 is formed, the lower surface of which is inserted after the tube is inserted via an annular seal. 4 rests on the upper edge of the container 3.
  • the ring seal 4 can be inserted into a flat groove in the upper edge of the container 3.
  • the collar 2 consists of a sufficiently elastic material with sealing properties, the ring seal 4 is unnecessary.
  • the necessary contact pressure is generated by the upper part 7 of the container 3, which is screwed to it in the exemplary embodiment, but can also be connected, for example, by a bayonet lock.
  • the collar 2 is connected in one piece to the tube 1 or another disposable packaging, for example a cartridge with a displaceable base (not shown) which acts as a piston.
  • the collar 2 can either be produced together with the tube 1 or subsequently welded or sealed after it has been filled.
  • the collar 2 has an outlet opening for the product, which is closed by a rubber stopper 5. Opposite the rubber stopper, there is a sharpened hollow needle 6 in the upper part 7 of the container, which is connected to a product valve 8 of a conventional type. When the upper part 7 is screwed onto the container 3, the hollow needle 6 pierces the rubber stopper 5. This creates a sealed connecting channel between the tube 1 and the product valve 8. No product can escape into the space between the top of the collar 2 and the thread of the upper part 7, especially since the interior of the container 3 is still depressurized at this time. The same applies when the upper part 7 is removed for changing the tube 1, because on the one hand the propellant gas pressure escapes, on the other hand the rubber stopper 5 ensures that the puncture site of the hollow needle 6 closes tightly.
  • the so-called stem 11 of a portioning valve 12, which belongs to a liquid gas storage container 10, is screwed tightly into a bore in the bottom 9 of the container 3.
  • the portioning valve is opened by axial pressure on the bottom of the gas storage container 10 and only allows the amount of propellant gas required for the complete emptying of the disposable packaging used to be exceeded. This ensures particularly economical propellant gas consumption. So that the gas storage container 10 can be screwed into the threaded bore in the base 9 sufficiently tightly to achieve a tight connection via the stem 11 of its portioning valve, the stem 11 and the gas storage container 10 are connected to one another in a rotationally fixed manner.
  • Figures 2 and 3 show further embodiments of the collar, which is designed here as a screw collar.
  • the screw collar 2a has a flat top, which (as in the case of FIG. 1) can thus serve as a standing surface for the tube.
  • the screw collar 2b has a cylindrical extension which fits into a recess (not shown) provided in the upper part of the container. This allows more space to be gained.
  • the screw collar has a seal 4a on the underside with a round or rectangular cross section, which takes the place of the ring seal 4 in FIG.
  • the screw collars 2a, 2b are provided with a passage opening for the product to be dispensed, which is closed on the inside with a thin sealing plate 13 which takes the place of the rubber stopper 5 of FIG. 1 and is later perforated by the hollow needle 6 (FIG. 1).
  • FIG. 4 shows a screw collar similar to FIG. 2, but with a passage opening for an emptying spout 2c, as is particularly suitable for dispensing pasty products.
  • the product valve in the upper part of the container is designed in a manner known per se as a pinch valve.
  • the emptying nozzle 2c is passed through the opened pinch valve and the excess is cut off.
  • the emptying nozzle 2c can also be an integral part of either the screw collar or the disposable packaging itself.
  • the outside diameter of the disposable packaging used is only limited by the inside diameter of the container 3 (FIG. 1), but can also be arbitrarily smaller, it is expedient to provide the collar with suitable centering means, such as an annular groove or a centering collar (not shown).
  • suitable centering means such as an annular groove or a centering collar (not shown).
