Definitions

  • the inventions relate to the technical field of packaging technology. Specifically, an invention relates to a container whose contents are easily removable by a consumer, in particular under an increased internal pressure in comparison to the external pressure. Specifically, another invention relates to a pressure valve for said container. Specifically, yet another invention relates to a control method for pressure in a container.
  • the container is comparatively bulky, significantly larger than a common beverage can and the content is a drink that is to be tapped under pressure.
  • Portable beer kegs those with a volume of less than 50 liters, especially less than 20 liters and more than 2.5 liters, whose content can be tapped by consumers independently are in two common variants of particular importance.
  • a variant of such, provided with metallic mantle, portable beer kegs can be emptied by the action of gravitational force.
  • a tap is arranged in the lower region of the outside of the container. By opening the tap, the beer can flow out. So that no negative pressure arises in the container, such containers comprise a device which allows air from the environment to reach the interior of the container.
  • Such containers are not very user-friendly, since to fill a glass with beer, the keg must be placed, for example, on the edge of a table or the keg must be supported in order to be able to fill the glass below the tap.
  • the durability of the drum contents after the start of the barrel is significantly reduced by flowing in the outflow of the beer atmospheric oxygen.
  • containers comprising an internal pressure system.
  • the pressure inside is kept above the ambient pressure. This allows the arrangement of the tap in the upper region of the container.
  • a consumer typically has sufficient space between the lower outlet end of the tap and the level of the container to hold a glass to be filled under the tap, without having to specially position the keg.
  • the shelf life of the beer can be up to more than 30 days after the start of the barrel, since no atmospheric oxygen flows into the keg during beer extraction.
  • a beer barrel system of the second variant is the expert from WO 1999/47451 (Heineken Technical Services).
  • a beer keg system which comprises a print cartridge, which is arranged in the interior of the beer-filled container space and generates an overpressure in this space.
  • the print cartridge comprises activated carbon, whereby a larger amount of pressurized or propellant gas can be introduced into the cartridge with respect to a not provided with activated carbon cartridge without raising the pressure in the cartridge too much.
  • these cartridges are called "carbonator”.
  • this system has proven to be the best-performing solution for portable beer kegs in the market under 20 liters in the market. It became, so to speak, the market standard.
  • the invention face the task to provide a system that is inexpensive to manufacture with high ease of use by a consumer, a high flexibility in terms of the choice of fuel gas (pressure and type of gas) provides and a long shelf life of the content, even after opening container.

A marginal fluid flow or fluid exchange will also take place between two fluid-tight spaces separated from each other, wherein the pressure difference between the two spaces has an influence on the amount of the parasitically exchanged fluid per unit time. In any case, the fluid exchange in the closed state of the pressure valve, so fluid-tight, much lower than the fluid exchange in the open state of the pressure valve, so fluidkommuniplasticd.
