Definitions

  • the present invention relates to a spray can filled with a propellant gas according to the preamble of claim 1.
  • Pressure relief valves are known from many areas, which could certainly meet the requirements, but the use of such pressure relief valves is not a practical solution for the area of spray cans, since, among other things, they are designed and are therefore very expensive to manufacture.
  • the present invention is therefore based on the object of designing a spray can of the generic type in such a way that it is possible to drain with structurally simple means when a critical overpressure is reached and the functionality of the spray can is then fully retained.
  • the openings through which the spray can contents, in particular part of the propellant gas, can escape when a defined critical overpressure is exceeded, can be introduced without additional work steps in the manufacture of the valve disk, so that this results in a very inexpensive manufacture.
  • the openings can be provided in any area of the valve plate, which represents a closure against the interior of the spray can.
  • a particularly advantageous embodiment of the invention is that the openings are provided in the plate dome.
  • they can be arranged in the jacket area or, according to a further concept of the invention, in the face area.
  • the openings are made before the plate dome is produced by appropriate deformation, the openings advantageously being punched out.
  • a closing means for example, spring-loaded slides can be provided which, in the event of a critical overpressure, open the openings to such an extent that the propellant gas can escape until the excess pressure is released. Then the slides are brought back into their closed position due to the spring action.
  • an elastic hose part is placed over the plate dome as a closing means so that the openings are covered at operating pressure.
  • the hose part is stretched so far that the medium under pressure can escape. Once the excess pressure has been released, the hose part rests on the outer surface of the plate dome due to its elasticity, so that the openings are sealed gas-tight.
  • the plate dome 2 is provided with openings 3 arranged in the casing region 5, which are preferably arranged at the same distance from one another and lying in a common plane.
  • the hose part 4 shows a situation as it arises when the medium in the spray can exceeds a defined excess pressure.
  • the hose part 4 is lifted from the outside of the plate dome 2 to such an extent that the medium can escape to the outside.
  • the pressure falls below a critical value
  • the hose part rests on the plate dome 2 due to its elasticity and closes the openings 3 until a renewed overpressure inside the spray can in turn leads to a lifting of the hose part 4.
  • a permanent opening and closing of the openings 3 is possible if necessary.
  • the material of the hose part 5 must be selected.
  • a gas-tight closure up to, for example, 18 bar still meets the safety requirements.
  • the elastic forces of the hose part 4 are lower, so that the hose part lifts off the wall of the plate dome 2 and the spray can contents can partially escape.
  • the overpressure e.g. is 1 bar healthy, the hose part lies gas-tight on the openings 3.
  • FIG. 3 An embodiment of the invention as shown in FIG. 3 also functions in this sense.
  • the openings 3 are provided in the end region 6 of the plate dome 2, the openings 3 being distributed in the form of a ring at the same distance.
  • openings 3 can of course be introduced anywhere in the valve plate 1 where there is a direct transition to the interior of the spray can. It is important, however, that the openings 3 are sealed gas-tight at operating pressure.
