Definitions

  • the invention relates to a device for the gas-tight packaging of articles with closely to the objects applying sheet material using a vacuum, preferably for carrying out the aforementioned method, comprising a support for at least one shell and comprising at least one sealing tool for the thermoformable film. Finally, the invention relates to a package.
  • Devices of the aforementioned types are used to package objects.
  • These articles may be inorganic products, such as tools or stationery, which are held in suitable packaging for sale in markets.
  • the articles may be organic products, such as food.
  • meat and sausage products are packed with this type of packaging in order to leave the smallest possible gas volume in the interior of the packaging.
  • the procedure is such that an object is placed in a dish and then the thermoformable film is welded to the shell.
  • the film is cut to the size of the shell, this is often done a cutting of foil and Shell in one step, z. B. when slipping of the shell occurs.
  • sharp shell edges can be formed.
  • this subsequent cutting is done on the still heated for welding film.
  • the film has a soft consistency in its heated state so that it can provide little resistance to a cutting knife. As a result, blurred cut edges, which lead to an unsightly creasing and discarding the cut edges of the film.
  • the object of the invention is to disclose a device with which it is possible to package objects in suitably configured gastight packaging.

  • In the Distance plate is preferably arranged at least one with the container in congruent position bringable breakthrough. This breakthrough then has dimensions corresponding to the sealing tool.
  • the cutting device preferably comprises knife blades, with which a cutting of the thermoformable film is successfully carried out.
  • the cutting device is spatially associated with the sealing tool. Due to this spatial assignment, a temporally short successive sealing and cutting can take place.
  • the assignment of cutting device and sealing tool to each other is given spatially, structurally, both modules are independent of each other to allow a separate performing the operations sealing and cutting.
  • the cutting device can rotate the sealing tool. If the sealing tool is rectangular, for example, knife blades of the cutting device can circulate this sealing tool like a frame. After placing the sealing tool on the film is done with the frame-like knife blades cutting the same.
  • a development of the invention provides that the support for the shell and / or the sealing tool are guided vertically variable. Pad and sealing tool can thus be approximated and removed from each other. The approach is used to place the sealing tool on the thermoformable sheet when the cutting tool still maintains a distance from the peripheral edge of the tray.
  • a next development of the invention provides that the support at least one support means for the peripheral edge of the shell having.
  • the shell can be introduced by means of the support in the support device for the peripheral edge.
  • the peripheral edge is preferably placed on this support means so that it is ready for welding or sealing with the thermoformable film.
  • the support device supports the peripheral edge and forms an abutment for the specialtylegende on the edge sealing tool.
  • the cutting device When using the spacer plate with the apertures, it is advantageous to assign the cutting device spatially to the sealing tool.
  • the cutting device is preferably like the sealing tool through the breakthrough of the spacer plate feasible.
  • the cutting tool is preferably uncoupled from the sealing tool and resiliently mounted. This decoupling makes it possible to bring the sealing tool closer to the shell first than the cutting tool.
  • a seal between the film and shell success foil is used.
  • the cutting tool is guided in a corresponding guide to the plane of the surface of the peripheral edge. The lying on the peripheral edge thermoformable film is cut, but the knife is not moved into the peripheral edge. The peripheral edge remains intact.
  • the sealing tool is disposed on the side of the thermoformable sheet, which is turned away from the shell.
