Definitions

  • the invention relates to a gas-permeable vessel closure.
  • Liquid containers especially large liquid containers, require an effective seal.
  • This seal must be gas-permeable for liquids under vapor pressure in order to avoid the risk of bursting or an explosion.
  • Such filled liquid containers must also be able to be transported and moved.
  • Gassing liquids are, for example, H 2 0 2 , chlorine bleach.
  • this crystallization preferably takes place in the part of the vessel wetted by the surge, at the upper edge and at the closure.
  • the present invention has for its object to provide a gas-permeable vessel closure, in which there is no blockage and sealing by deposited crystals, in which permanent gas exchange is guaranteed and in which the gas-permeable membrane is not wetted by liquid.
  • the gas-permeable vessel closure according to the invention are characterized in that the gas-permeable seal contains a degassing membrane (8), that the smooth side of the degassing membrane (8) is arranged lying towards the inside of the vessel, that the gas-permeable seal contains a perforated disc (5) that the Gas-permeable seal contains two or more perforated disks (4, 5), that the degassing membrane (8) is arranged between the perforated disks (4, 5), and that perforated disks (4, 5) and / or degassing membrane (8) with one or more flat seals (7) are provided.
  • the cavity (10) is formed by a spherical sleeve (1) which is provided with openings (11) towards the interior of the vessel, that the ball bushing (1) and gas-permeable seal are arranged in a screw cap (2), that the ball bushing (1), gas-permeable seal and screw cap (2) are arranged in a cap (3), that the ball bushing (1) from the rim of the vessel (12) is separated by a flat gasket (6) that the cavity (10) of the ball bushing (1) is partially filled with packing elements (9), that chemically inert plastic balls, preferably made of polyethylene, in particular in granular form, are used as packing elements (9) the cavity (10) of the ball bushing (1) with packing (9) to the perforated disc (5) is filled with granules, and that the degassing membrane (8) on the side facing the interior of the vessel with chemically inert and resistant material, especially polytetrafluoroethylene, coated is.
  • the packing acts as surge inhibitors, to which crystallizates adhere even in the case of a surge, but which are brought down again in the next surge.
  • the filling bodies are wetted by the surge up to a certain height.
  • the beads which are in loose packaging, are lifted into the free space or there is a change in the packing density, which is accompanied by the self-cleaning effect.
  • the vessel closure according to the invention also offers the possibility of use on large surfaces, eg of containers.
  • Figure 1 shows a longitudinal section through a gas-permeable vessel closure according to the invention.
  • a ball sleeve 1 is arranged in and above a vessel opening with the vessel edge 12, which is provided with openings 11 to the interior of the vessel.
  • the ball bushing 1 is covered by two perforated disks 4, 5, between which a degassing membrane 8, the smooth side of which is arranged to lie inside the vessel, is separated from the perforated disks 4, 5 by flat seals 7, and is supported.
  • the gas-permeable seal formed in this way is arranged on the inside on the underside of a screw cap 2; the screw cap 2 is in turn arranged on the underside of a cap 3.
  • Screw lid 2 and cap 3 are pulled down over the vessel edge 12 of the vessel.
  • the filling elements 9 are introduced into the cavity 10 of the ball bushing 1.
  • Figure 2 shows a cross section through the gas-permeable vessel closure according to the invention.
  • the outer concentric ring 13 provides the outer edge of the sleeve 1 and gas-permeable seal, consisting of perforated disks 4, 5 with holes 14 in cap 3 and screw cap 2, formed closure.
  • the closure has gas outlet openings 15th
  • the present invention represents a membrane closure, a closure with a valve effect.
  • the membrane can, for example, be coated with a chemically inert material, such as polytetrafluoroethylene, so that it cannot be attacked chemically, in particular on the inside of the vessel.
  • a chemically inert material such as polytetrafluoroethylene
  • the packing can be of any shape and type; spherical ones are preferred in terms of self-cleaning and packing density.
