Definitions

  • the invention relates to a container for pressurized gases, wherein a mouth of the container is covered with a valve plate carrying a valve, and the valve plate has at least one notch reducing the thickness of the valve plate as a safety valve.
  • an impermissible pressure increase can occur, for example due to the decomposition of hydrogen peroxide or an inadmissibly high temperature.
  • US Pat. No. 3,074,602 describes a punctiform or annular indentation in the valve plate, which tears open when the valve plate is deformed due to excessive pressure.
  • US 3,918,610 shows a container according to the preamble of claim 1, in the valve plate of which an encircling bead is stamped in an outer edge region, which is interrupted by six radially extending webs.
  • two of the webs are each provided with a notch that runs across the web and continues on the side walls of the web and over a short piece of the bottom of the bead adjacent to the web.
  • annular notch is known as a safety valve of a container, which is provided in the jacket of the container.
  • a corresponding safety valve which is however arranged in a cover of a container, is known from EP 0 262 070 A.
  • the trigger threshold In order to ensure that the safety valve is triggered at a specified pressure and to prevent unwanted triggering due to mechanical stress during transport, use or when the contents of the aerosol can are still warming up, the trigger threshold must be determined as precisely as possible when manufacturing the aerosol can required. However, this is not possible with the known aerosol cans, in which a deformation of the valve plate is required to trigger the safety valve.
  • the object of the present invention is to propose a container for pressurized gas liquids with a safety valve which is simple and inexpensive to manufacture and which triggers as precisely as possible at a predetermined pressure.
  • the notch runs in a ring shape and encloses an area whose size results in a force sufficient for tearing at the notch at a predetermined overpressure inside the container.
  • a particularly large effective area is possible in that the area includes the axis of the valve.
  • the thickness of the valve plate on the indentation can be chosen so large that the tolerances of this thickness required in terms of the most accurate release pressure can be observed when using conventional punching tools.
  • the container according to the invention has the advantage that no further parts are required. This saves material and costs.
  • the annular notch In the context of the invention, it is not necessary for the annular notch to have the shape of a circle.
  • the notch can be made on the inside as well as on the outside of the valve plate.
  • the indentation forms a closed ring
  • the inner part of the valve plate may be flung with the valve when the safety valve is triggered. Since this is undesirable in many cases, it is provided in a development of the invention that the notch is interrupted at one point on the circumference. It has proven to be advantageous if the interruption takes a circumferential angle between 10 ° and 90 °.
  • a container for pressurized gas in which the valve disk is designed in an inner region for receiving a sealing washer, which is between an edge folded in the direction of the valve axis and a disc-shaped part of the edge spaced from the edge Valve plates is held.
  • the notch is arranged in the disk-shaped part.
  • the notch is arranged in an edge region of the disk-shaped part.
  • the sealing washer can easily come out through the opening that is formed in the event of triggering.
  • the diameter of the annular notch can be varied, for example with regard to the trigger pressure, and may be smaller than the diameter of the sealing ring disk. However, it should be provided that the diameter of the annular notch corresponds substantially to the diameter of the sealing washer.
  • the disc-shaped part has a circumferential shoulder and that the notch is arranged outside the circumferential shoulder.
  • a notch 5 running concentrically around the valve axis is provided as the predetermined breaking point.
  • the indentation at 6 is interrupted over a circumferential range of approximately 60 °, so that when the indentation 5 is triggered, the part located within the indentation 5 does not completely detach from the valve plate, but merely tilts (FIG. 4).
  • the remaining parts of the embodiment shown in the figures are known per se, for example from DE 29 16 699 C2. An explanation of these parts is only made below, insofar as it is necessary to understand the invention.
  • the only indicated aerosol can 7 has a mouth flanged at 8 at the edges, which is closed with a valve disk 9, a seal 10 being provided.
  • the valve disk 9 is shaped in such a way that the edges of a valve seal 13 and a membrane 14 are clamped between an inward circumferential fold 11 and a disk-shaped part 12.
  • the membrane 14 is connected in one piece to a closure body 15 which contains passage channels for two liquids located in the aerosol can and in an elastic container (not shown) within the aerosol can.
  • the valve is opened by pressure on a foam head 16, an extension 17 of the foam head penetrating into a blind bore 18 of the closure body and moving it downwards so far that the passage channels are released from the seal, and the liquids via grooves 19 at the lower end of the Extension 17 can flow into the foam head 16.
  • the predetermined breaking point 5 tears open at an overpressure, so that the inner part of the valve plate tilts up with the valve. Suitable tolerances prevent the foam head (not shown in FIG. 4) from obstructing this tilting.
  • this annular holder can be chamfered at the upper outer edge so that it is together with the seal 13 in the case of a Triggering of the safety valve slips out of the valve plate.
