Definitions

  • the invention relates to a device for vacuum-tight sealing of containers, in particular for perishable goods, such as food, paints and the like.
  • the object of the present invention is therefore to provide an inexpensive and easy-to-use device for vacuum-tight sealing of containers, which can be used in a variety of ways.
  • the device according to the invention is inexpensive to manufacture and easy and safe to use. It is equally suitable for households and the commercial sector.
  • the vacuum required for durability can be adjusted with little effort using a relatively simple vacuum monitor and a permanently connected vacuum pump.
  • the device according to the invention is versatile, in particular also as a built-in device in refrigerators and coolers.
  • the drawing shows a device for vacuum-tight sealing of containers.
  • the device comprises a container 2 with a bottom 4 and four side walls 6, 7, 8 and 9.
  • a lid 10 can be placed, which has a peripheral downwardly projecting edge flange 12 which overlaps the edge 14 of the container on the outside and which is provided on the underside with a circumferential seal 15 for tight support on the edge 14 of the container 2.
  • the interior of the container can be divided into several sub-spaces 20 by removable partitions 16, 18, which are connected to one another via openings 22 provided in the partitions.
  • the partition walls 16, 18 serve primarily to stabilize the container 2.
  • Removable insert containers 24 which can be closed by means of covers 23 are inserted into the subspaces 20 created by the partition walls 16, 18. It is also possible to omit the partitions if the insert containers stabilize them. It is also possible to use the container 2 as such with the partition walls without the insert containers.
  • connection 26 for a vacuum pump 28 and a connection 30 for a ventilation valve 32 and / or a vacuum gauge or a pressure sensor 34.
  • the vacuum pump 28 can and may be manually or motor-operated permanently connected or connectable if necessary.
  • the described device is used for preservation as follows of perishable goods such as food, paints, etc.:
  • One or more of the insert containers 24 located in the container 2 is or are filled as completely as possible with the perishable goods to be stored and are closed with the lid 23.
  • the container 2 is then closed with the lid 10 and evacuated with the aid of the vacuum pump 28 via the connection 26.
  • the set negative pressure can be read on the manometer or detected with the pressure sensor 34. Different negative pressures are regularly required for different goods.
  • the vacuum pump is switched off manually or electrically via the pressure sensor. If the target vacuum is exceeded, the target vacuum must be restored, which can be done manually or automatically. Monitoring and maintenance of the target negative pressure can be carried out automatically via the pressure sensor 34 and a vacuum pump 28 which is constantly connected and connected to the pressure sensor.
  • the lid 10 Due to the negative pressure created in the container 2, the lid 10 is pressed firmly onto the container, which is thereby hermetically sealed at the same time. At the same time, the negative pressure also arises in the insert containers.
  • the container 2 is ventilated via the ventilation valve 32. Due to the resulting differential pressure between the interior of the insert containers 24 and the interior of the container 2, the covers 23 are pressed firmly onto the insert containers, which are thereby closed in a vacuum-tight manner.
  • the sealed insert containers can be removed and additionally stored, for example, in a refrigerator and the like. However, they can also remain in container 2.
  • the closed insert containers 24 again can be opened, they are equipped with a ventilation valve 36 or with another suitable device, for example a pull tab provided on the cover seal (not shown).
  • the container 2 can be used even without the insert containers 24 and possibly also without the partition walls 16, 18.
  • the containers 2 can be used separately or as built-in devices for refrigerators, boxes, etc.
