Definitions

  • the invention relates to a protective cap for the bunghole closure of a liquid container.
  • Liquid container with a bung hole, where a bunghole closure is located are widely known in practice. Specifically, it is about bunghole closures on containers for drinks. Examples of such containers are barrels, small barrels (party kegs) or cans, which are filled without pressure or under pressure with the respective beverage; think of party kegs for beer in particular.
  • a bunghole closure with a pressure compensation valve is known, which is the filling opening on the top floor of a party keg closes.
  • a seated in the bung closure valve rotary plug is rotated by hand.
  • the party keg has a separate lower discharge opening with an integrated drainage tap for the liquid withdrawal.
  • a negative pressure When unpressurized removal of liquid from the lower discharge opening is formed above the liquid level in the container, a negative pressure.
  • the container can be aerated by means of the pressure compensation valve to reduce this negative pressure.
  • the object of the invention is to provide a protective cap that prevents unwanted manipulation of the pressure balance valve and ensures a tamper-evident.
  • the task solving protective cap is of circular cylindrical cup shape. It has an outer cylinder jacket ring that fits over the bung closure and permanently stops it.
  • the outer periphery of the cup bottom takes a bottom ring, which is connected with predetermined breaking points to the cylinder jacket ring.
  • a grip tab In the center of the center of the cup, there is a grip tab, which is hinged to the bottom ring with a film hinge.
  • four offset by 90 ° predetermined breaking points for the bottom ring are provided. But it can also be more or less than four.
  • the grip tab is connected with predetermined breaking points on the bottom ring, which tear more easily than the predetermined breaking points between the bottom ring and cylinder jacket ring.
  • predetermined breaking points Preferably, two diametrically opposite predetermined breaking points are provided for the grip tab.
  • a finger opening is provided on the side opposite the film hinge side between the grip tab and the bottom ring.
  • the grip tab is provided with grip ribs.
  • a holding web projects inwards at the lower edge of the cylinder jacket ring.
  • the holding web is preferably segmented over the circumference. But he can also go over the scope.
  • the protective cap according to the invention has a preferred use for a bung closure with a pressure compensation valve. Mind you, it can also be used for other bung-hole closures.
  • the protective cap is of circular cylindrical cup shape. It has an outer cylinder jacket ring 10, which represents the cylinder cup jacket, and a bottom ring 12 and a gripping tab 14, which together represent the cylinder cup bottom.
  • the protective cap fits with the cylinder jacket 10 via a bung closure.
  • a holding web 16 segmented over the circumference projects inwards.
  • the protective cap is slipped on a bunghole closure, the holding web 16 digs into its elastic material.
  • the cylinder jacket 10 thus has permanent hold on the bung closure. He can not be destroyed without destroying it.
  • the bottom ring 12 occupies the outer periphery of the cylinder cup bottom. He is connected with four offset by 90 ° predetermined breaking points 18 to the cylinder jacket ring 10.
  • the gripping tab 14 is hinged thereto at the inner edge of the bottom ring 12 with a film hinge 20. At the side opposite the film hinge 20, a finger opening 22 is provided between grip tab 14 and bottom ring 12.
  • the pull tab 14 is connected with predetermined breaking points 24 to the bottom ring 12.
  • the predetermined breaking points 24 are located in the middle between the Film hinge 20 and the finger opening 22. They are diametrically opposite each other.
  • the predetermined breaking points 24 of the pull tab 14 tear more easily than the predetermined breaking points 18 between bottom ring 12 and cylinder jacket ring 10th
  • the grip tab 14 is provided with grip ribs 26.
  • the protective cap may be preassembled on a bung closure before it is inserted into the bunghole, for example, to close the filling opening of a liquid container.
  • the protective cap can also be placed subsequently on the bunghole closure.
  • the protective cap thus fulfills the function of a tamper-evident closure in the manner of a seal.
