Definitions

  • the invention relates to a packaging container through which a liquid, a gaseous or a pasty medium, in particular a food, a liquid or a toothpaste is stored for transport purposes, according to the preamble of claim 1.
  • a packaging container is known has become, which is formed from a folding carton wall, in which there is a filled with a medium liquid bag. Adjacent to the bottom of the packaging container, an opening is incorporated in the packaging container, through which a connecting piece protrudes, for the removal of the medium, which can be provided with a tap, for example, for portioning the liquid.
  • Such packaging containers are also known as so-called "bag-in-box”.
  • packaging containers are unsuitable for gassed media because, on the one hand, the packaging container does not have sufficient holidays to absorb the pressure forces prevailing in the cavity and, on the other hand, such packaging containers have to be equipped with a standpipe or similar auxiliary means so that the entire contents of the packaging container is removable without having to be rotated or tilted to completely empty this.
  • a packaging container with a pressure-resistant wall can be found in DE 10 2014 007755A1.
  • the wall of the packaging container is formed of a non-stretchable material, for example of a fabric and / or a film, and in the cavity there is a liquid bag with the medium to be stored or transported.
  • the bag is made of a gas- and liquid-tight, mostly elastic plastic.
  • Attached to the bag is a connector which, through an opening, can expel the medium through the wall of the packaging container into the environment. It is particularly disadvantageous in this state of the art that such packaging containers can not be used - or only conditionally - for gaseous media. As soon as the packaging container is in fact opened and the gas-containing medium is removed, gas which dissolves the volume of the packaging container which has become vacant in the cavity is released from the remaining medium. As a result, the gas content in the medium continuously decreases and the quality of the medium or the quality of enjoyment decreases. The gas remaining in the packaging container leads to explosions that are dangerous.
  • a packaging container of the type mentioned through which a liquid, a gaseous or a passive medium, in particular gas-containing liquids, transported, stored and subsets of the medium can be removed without existing in the medium Can dissolve gases. Furthermore, it should be ensured that the medium stored in the packaging container is always exposed to a pressure, so that even media with a low viscosity can be discharged through the connector sufficiently quickly without leaving any residue in the container. lag behind.
  • a further object of the invention is to develop a packaging container in such a way that the medium can be removed at a constant dispensing speed over the entire emptying process and that the emptied packaging container can be compressed in a space-saving manner.
  • the packaging container should be inexpensive to manufacture.
  • a second gas- and liquid-resistant deformable bag is arranged, that the second bag with the first bag, the volume of the cavity completely or at least largely fills and that in the second bag, a connector is present that through the opening or a second opening is guided through the wall of the packaging container into the environment and by means of which the pressure state and / or the volume of the second bag can be set as a function of the pressure state and / or the volume of the first bag, the pressure state in FIG the medium filled bag can be adjusted and the medium are completely displaced from the bag.
  • the dissolution of the gas is prevented by the generation of a pressure state in the first bag and the medium is not scarf over a longer storage period in the open state.
  • the wall of the packaging container is made of a rigid material, preferably sheet metal, wood or a solid plastic, or that the wall of the packaging container is made of a deformable material, preferably a tensile and / or or tear-resistant fabric.
  • the first bag completely fills the cavity with the medium in the unopened state of the packaging container. After opening the packaging container and partially expelling the medium through the connector, the volume of the cavity released from the first bag is fully balanced by an increase in volume of the second bag.
  • a gas, a gas mixture, a liquid or a gas-liquid mixture can be pressed by means of a pressure generator, so that in the first bag, a printing state is maintained.
  • the pressure for carbonated or nitrogen-containing media is in this case preferably between 2.5 and 5 bar, but this pressure can also be up to 15 bar, depending on the filling and the ambient conditions.
  • the first and second bags are preferably adapted to the dimensions of the cavity and the volume of the bags corresponds to the volume of the cavity.
  • the bags of the packaging container can be made of a plastic, for example polyethylene, polypropylene or polyurethane plastic mixture. Other gas and liquid-tight, natural or synthetic materials and material mixtures are conceivable.
  • the pouches can be produced in multiple layers and have a protective layer, for example a UV protective layer, in order to prevent the penetration of UV rays into the interior of the pouch.
  • the connecting pieces may be fastened in a reinforced region on the bag, for example by means of ultrasonic bonding or the like, and may have a valve, preferably a directional control valve, and / or a tap.
  • the wall of the packaging container is formed from a tubular, bag or silo-shaped fabric tube.
  • the open ends of the tissue tube may be closed by a suture and / or a weld and / or a concatenation.
  • High-strength synthetic or natural fabric fabrics, for example nylon or the like, are particularly suitable as material for the fabric.
  • the walls of the packaging container can be reinforced by a material additive.
  • valve and / or a cock can be arranged in the connecting pieces of the first and the second bag and / or a coupling device can be connected by means of the packaging container to a system for dispensing the medium and / or to supplying a pressurized gaseous medium can be.
  • Figure 1 shows a first embodiment of a packaging container, consisting of a wall through which a closed cavity is formed, with a first bag which can deliver a medium by means of a connecting pieces through an opening of the packaging container and a second bag, by means of a pressure generator creates a pressure state in the cavity of the packaging container,

  • the bags 10, 11 are made of a mostly elastic plastic or plastic mixture, for example polyethylene, polypropylene, polyurethane, polyamide, or the like.
  • the bags 10, 11 may be formed, among other things, as flat bags, gusseted bags, stick packs, tubular bags or multiple suture bags whose sides are pressure-tight and gas- and liquid-tight by means of one or more welds 19.
  • the first bag 10 is completely filled with the medium 2 and the first bag 10 fills the entire cavity 5.
  • the first bag 10 is locked by the valve 13.
  • the second bag 11 is empty and is pressed by the pressure prevailing in the first bag 10 in the cavity 5 against the wall 3.
  • the pressure state in the bag 10 is for example in carbonated or nitrogen-containing media and moderate ambient temperatures about 2.5 to 5 bar, but the pressure depending on the medium to be transported or stored and the ambient temperature can be up to 15 bar. Without a support of the bag 10, 11 through the wall 3 of the packaging container 1, the bags 10, 11 would not withstand the pressure condition and burst or burst. The wall 3 thus supports the bags 10, 11 in the cavity 5 and the cavity 5, the maximum volume of both bags 10, 11, so that they are not elasto-plastic, plastic, so irreversible, deformed and withstand the pressure.

  • the second bag 12 is to be transferred by the pressure generator 15 in a pressure state and the second bag 11 occupies the freed by the removal of the medium 2 volume.
  • the pressure generator 15 can press any gas or liquid mixture into the second bag 11. Regardless of the position of the connecting piece 12 of the first bag 10, the entire contents of the emptying of the packaging container 1 by the pressure state of the second bag 12 is pressed so that no unnecessary residues remain in the bag 10.
