Definitions
- the invention relates to a container for liquids pressurized by gas, with a mouth of the Container with a valve plate carrying a valve is covered and the valve plate is at least one the thickness of the valve plate reducing notch as Has safety valve.
- Preventing the content of the aerosol can is one possible precise definition of the trigger threshold during manufacture the aerosol can is required. However, this is with the known aerosol cans, in which to trigger the Safety valve a deformation of the valve plate is not possible.
- the object of the present invention is a container for pressurized liquids with a To propose a safety valve that is simple and inexpensive is producible and that is given as precisely as possible with one Triggers pressure.
- the Indentation is ring-shaped and encloses a surface, the size of a given overpressure inside the Container sufficient to tear open the notch Force.
- the notch and the one enclosed by it can Surface to be arranged laterally from the valve.
- a special one large effective area is possible, however, that the Surface includes the axis of the valve.
- the thickness of the valve plate on the notch can still be so be chosen large, that in the sense of a possible exact release pressure required tolerances this Thickness when using common punching tools can be met.
- the invention Container has the advantage that no additional parts are required are. This saves material and costs.
- the ring-shaped notch has the shape of a circle.
- the Notch can be on both the inside and the Be made outside of the valve plate.
- the indentation forms a closed ring, the inner part of the valve plate with the valve if necessary flung when the safety valve is triggered. Since this is undesirable in many cases, one is Further development of the invention provided that the notch is interrupted at one point on the circumference. It did turned out to be favorable if the interruption occupies a circumferential angle between 10 ° and 90 °.
- the sealing washer is made of elastic material, the diameter of the ring-shaped notch, for example with regard to the trigger pressure and possibly smaller than the diameter of the Sealing ring washer. However, this should be provided be that the diameter of the annular notch in essentially the diameter of the sealing washer corresponds.
- Another advantageous embodiment of the training of Invention is that the disc-shaped part has circumferential paragraph and that the notch outside of the circulating paragraph is arranged.
- Fig. 1 shows a top view of a valve plate Aerosol can with a mounting collar 1, one flanged mouth of an otherwise not shown Aerosol can encloses, and a delivery nozzle 2.
- the safety valve On the from the fastening collar 1 and the delivery nozzle 2 enclosed annular surface 3 is located the safety valve in the form of an annular one Notch representing breaking point 4.
- the notch 4 can from the inside, as shown in Fig. 1, or from the outside be made.
- FIG. 2a shows a cross section through part of the surface 3 of the valve plate in the closed state, while Fig. 2b that is triggered as a result of overpressure and is therefore open Represents safety valve.
- the embodiment is concentric about the valve axis running notch 5 is provided as a predetermined breaking point.
- the notch is over a circumferential range of approximately 60 ° interrupted at 6, so that when the part located within the notch 5 detaches completely from the valve plate, but only tilts (Fig. 6).
- the remaining parts of the in FIGS. 3 to 6 illustrated embodiment are known per se for example from DE 29 16 699 C2. An explanation of this Parts will only be made in the following, as far as Understanding of the invention is required.
- the only The indicated aerosol can 7 has one at the edges at 8 flanged mouth, which with a valve plate 9th is closed, a seal 10 being provided.
- the valve plate 9 is shaped such that between one inward circumferential fold 11 and one disc-shaped part 12 the edges of a valve seal 13 and a membrane 14 are clamped.
- the membrane 14 is integrally connected to a closure body 15, the Through channels for two in the aerosol can and in one not shown elastic container within the Contains liquids contained in the aerosol can.
- the valve is opened by pressure on a foam head 16, a Extension 17 of the foam head in a blind bore 18 Closure body 15 penetrates and this far down that moves the passageways from the seal are released and the liquids via grooves 19 am lower end of the extension 17 flow into the foam head 16 can.
- the predetermined breaking point 5 tears overpressure so that the inner part of the Valve plates with the valve tipping up. Doing so by means of suitable tolerances, that the one in FIG. 6 Foam head, not shown, hinders this tilting.
