Definitions

  • the invention relates to a closure with degassing valve for filling and removal openings of liquid containers, in which a gas-permeable micro-filter laminate disc is attached with its outer edge surface within an annular groove of the closure below the outwardly open degassing opening.
  • a closure is described in GB-A-1 146 972.
  • Zippers serve as closures. B. releasable plugs or press closures, screw or bung closures.
  • Closures are required which prevent the passage of liquids or solids, but which prevent the passage of gases, if possible in both directions, i. H. should enable pressure equalization.
  • vent closures are required in the form of specially designed closures, so-called vent closures, also for closing storage and transport containers for liquid or solid substances.
  • overpressure or underpressure can occur after filling and closing.
  • a negative pressure can e.g. B. arise by cooling warm filled liquids.
  • An overpressure can e.g. B. form by decomposition or degassing of the container contents, the decomposition can be accelerated many times by unintentional or unavoidable increase in temperature during transport or storage and / or by catalytic influences.
  • the overpressures or underpressures can become so great that the valves can be destroyed.
  • Micro filter laminate panes have proven to be cheap degassing closures.
  • the filter disc must not be dimensioned too small, otherwise the passage cross-sections are not sufficient to allow such gas pressures to escape in a short time.
  • the panes are large enough, it has been shown that a sufficient amount of passage is achieved at the right time, but then the pane material is overstressed and tears.
  • the task is to ensure non-destructive storage of the valve disc in the operating device in rough operating conditions, with the largest possible gasification and disc surface area being available.
  • the rising space behind the disk attachment in the closure is constricted stepwise to the central axis of the closure to form an upper ring surface, the inner ring edge of the surface forming the lower opening edge of the degassing opening and the bulge limitation of the valve disc.
  • the increasing internal pressure can escape to the outside via the free space behind the fixing parts of the disc and from there through the degassing opening to the outside.
  • a further increase in pressure bulges the disc upwards until it lies against the ring edge of the constriction and is supported against further movement upwards.
  • the support system is gas-permeable, so that the entire pane surface is available outside of its fastening surface as a degassing surface.
  • the ring edge which acts as a support shoulder, prevents inadmissible bulging and thus overextension of the disc.
  • annular sleeve can be integrally formed on the bottom of the closure, the inside diameter of which corresponds to the outside diameter of the valve disk with play.
  • the micro-filter laminate disc 2 is glued into the closure device 1 in an annular groove.
  • a free space rises up behind the pane fastening 5, which is constricted step-wise to the central axis of the closure 1 to form an upper ring surface 3.
  • the inner ring edge 6 forms the lower opening edge of the degassing opening 4 and also serves to limit the bulge of the valve disk 2.
  • annular sleeve 7 is integrally formed on the bottom of the closure device 1, the inside diameter of which corresponds to the outside diameter of the valve disk 2 with play.
  • An annular seal is located in a recess in the neck below the bung thread. 8th.

Claims (2)

1. Fermeture (1) avec une soupape de sûreté pour des ouvertures de remplissage ou de prélèvement de récipients de liquides, où un disque aggloméré micro-filtrant (2), perméable aux gaz, est fixé par sa surface périphérique dans une rainure annulaire de la fermeture (1), située en dessous de l'ouverture de dégagement de gaz communiquant avec l'extérieur, caractérisée en ce que l'espace vide s'élevant dans la fermeture derrière la fixation (5) du disque (2) se resserre vers l'axe médian de ladite fermeture (1) en présentant un étagement avec une surface annulaire supérieure (3), le chant annulaire intérieur (6) de la surface (3) constituant le bord inférieur de l'ouverture de dégagement de gaz (4) et la limite à la déformation par bombage du disque de soupape (2).
2. Fermeture selon la revendication 1 caractérisée en ce que le fond de la fermeture (1) se prolonge par une douille annulaire (7) avec laquelle il forme une pièce unique, le diamètre intérieur de ladite douille étant adapté avec un certain jeu au diamètre extérieur du disque de soupape (2).
