Definitions

  • the invention relates to a closure cap for containers, canisters or the like. With a protected degassing valve.
  • Plastic barrels are already known to use self-sealing caps, which are equipped with a degassing valve, the general shape of which is reminiscent of a mushroom.
  • the valve is arranged deep in a recess designed for this purpose.
  • this position in a trough or bowl permits the accumulation of water around the closure cap, which results from atmospheric precipitation when such containers are stored outdoors. This water remaining around the cap can penetrate through the degassing valve into the container if, for example, a negative pressure is caused by cold or pressure surges.
  • the object of the invention is therefore to overcome this disadvantage by proposing a closure cap in which the degassing valve is protected from the ingress of a liquid by an attached lid which is located at the bottom of the depression or shell where the valve is located, has accumulated.
  • a closure cap according to the invention for containers, drums, canisters or the like is characterized with a degassing valve arranged in a shell recessed in relation to the upper edge of the cap, essentially in that the shell, at the bottom of which the valve is arranged, in the upper part by a cover is closed, which forms a chamber with the shell, which is connected to the outside air via a gas vent.
  • a self-closing cap 1 the body 2 of which seals any container, barrel or canister, has a degassing valve 3 which passes through the bottom 4 of a shell 5 formed in the top of the cap so that the valve is in its opposite the top 6 of the closure cap is protected position.
  • the body 7 of the degassing valve 3 has the general shape of a mushroom, which can stand out from holes 8 and 9 as a result of an internal pressure, thereby opening a passage from the interior of the container to the outside.
  • the degassing valve 3 is forcibly pressed with its bulbous lower end 10 into a passage 11 which is formed in the middle of the shell 5.
  • the vertical movements in this passage take place along the valve stem 12 and are limited at the top by its bulbous lower end.
  • the side walls 13 and 14 and the wall 15 of the bottom 4 of the shell 5 are formed in one piece in the body of the closure cap.
  • the valve is protected against various mechanical impacts and against the ingress of a liquid from the outside, for example water, by a cover 16 which is placed on the top 6 of the closure cap on its upper edge 17.
  • a gas outlet 19 is provided provided which ensures the degassing passage, so that enclosed gases, which have arisen from the material contained in the container or the liquid, can escape.
  • This gas discharge is preferably formed laterally in particular radially in the lid or in the body of the closure cap, so that penetration of rain water through this passage along the surfaces is avoided.
  • the gas exhaust 19 has the shape of a groove or a radial groove 20 which is longer than the thickness of the cap at the top edge, so that this groove or groove is exposed at the inner end and a free Passage for the gases between the shell 5 and the outside air guaranteed.
  • a radial gas outlet 19 in the form of a groove or groove which is formed in the body of the closure cap in its upper edge, for example in the form of a radial groove 21 (FIG. 7).
  • the cover 16 is a plastic disc which is fastened on the upper edge 17 of the closure cap or is firmly connected to the latter. Its top 22 can be made slightly curved to allow any water to drain away more easily.
  • the union or fastening of the cover 16 on the upper edge 17 of the closure cap can either be carried out directly on this surface, either by engaging a circumferential clamping projection 23 which is perpendicular to the plane of the cover and can be pressed into a complementary groove 24 (FIG. 1).
  • the lid can also have a ring shoulder 27 pointing downward with a transverse clamping projection 28 which engages in a corresponding groove 29 on the upper part 25 of the side face 26 of the cap (FIG. 2).
