Definitions

  • the invention relates to a bung container with at least one bung hole which can be closed in a liquid-tight manner by means of a bung plug.

  • DIN 6643 solid, pourable contents
  • sheet pans have an opening which is smaller than the inside diameter of the container and which is used for filling, emptying and venting the container. This opening can usually be closed by means of a security lock.
  • the bung container usually has a so-called Tri-Sure flange and a corresponding sealing plug.
  • a so-called Tri-Sure flange and a corresponding sealing plug For the formation of this flange and the associated sealing plug, reference is made to DIN 6 ' 643, part 2.
  • the Tri-Sure flange is manufactured as a separate part regardless of the actual container.
  • the flange is introduced into a container by a compression process, in which a seal adapted to the filling material is inserted between the container wall and the flange must be (cf. DIN 6643, part 2, VI safety lock).
  • the production is complex because the flange is produced independently of the container.
  • the pressure resistance of the flange is comparatively low.
  • the Tri-Sure flange has the further disadvantage that its resistance to deformation is low.
  • the creep barrier against hydroscopic goods is low; since there are no homogeneous material transitions, a seal adapted to the contents is required. Ultimately, containers with such flanges cannot be completely emptied.
  • the BÜCO Büdenbender company has therefore developed the so-called laser flange, which does not have the disadvantages described above, since the flange element is welded to the container wall by means of laser welding.
  • this flange has the disadvantage that its production is extremely complex.
  • the invention is based on the object of developing a bung container with at least one bung hole which can be closed in a liquid-tight manner by means of a bung plug in such a way that the actual bung flange can be produced simply and inexpensively, without the sealed sealability of the container suffering as a result.
  • An inventive solution to this problem is given in claims 1 and 9. Further developments of the invention are the subject of the subclaims.

  • the collar can also protrude outwards (claim 7) or inwards (claim 8).
  • the counter element can be, for example, a bayonet flange (claim 10) or a thread (claim 11). Accordingly, the clamping element is then a bayonet ring or a threaded ring.
