Fire extinguisher

The invention "relates to a fire extinguisher, in particular Handheld fire extinguishers.

The well-known fire extinguishers usually come with an elaborate one Yentilverschluß provided at the opening of the extinguishing container, which is firmly connected to the container, since the extinguishing substance in the container under high pressure or the propellant for the extinguishing substance constantly acts directly on the valve, in order to use this extinguishing container in the event of danger To put into action, it is necessary to unscrew the valves in a known manner.

It has also become known to use fire extinguishers, especially hand-held fire extinguishers, in which the container opening

Is not closed directly by a valve but by a thin cap made of sheet metal or the like. That is fixed sitting on the fire extinguisher. Above this cap is an attachment with an axially displaceable pointed pin arranged, with which the cap can be pierced, so that then the fire extinguishing agent from the container via ent-r speaking channels provided in the essay can emerge. But this fire extinguisher also has the disadvantage that the attachment is firmly connected to the container, so that the fire extinguisher can be used as a disposable container for cost reasons would be too expensive.

The invention has therefore set itself the task of providing a fire extinguisher, in particular hand-held fire extinguishers, which can be used as a disposable container that is no longer after Use must be refilled, is accountable for the costs. To cancel this task, the invention proceeds from the known Fire extinguisher, the container opening is provided with a cap and the one above the cap Carrying attachment with an axially displaceable opening pin. In contrast to known fire extinguishers of this type, the However, the invention provides that the attachment is designed to be easy to put on and remove from the closure cap. This will created the possibility of throwing away the actual container as a disposable part after the fire extinguisher has been used, But not the top cap, which is new

The fire extinguisher to be purchased can be put back on without difficulty can be.

According to a further feature of the invention it is provided that the attachment with a clamping effect on the closure cap or the container opening is to be put on. An embodiment is preferably selected for this in which the attachment is the closure cap the container opening from the outside in the manner of a cylinder. If necessary, in this cylinder part of the Attachment cuts can be provided, which increase the elasticity of the cylinder.

Finally, the invention provides that the attachment consists essentially of plastic and only the axially displaceable pin and the spring loading it is made of metal.

The attached model shows an example of the Invention in the form of a handheld fire extinguisher. This consists of an elongated container of circular cylindrical shape for the Extinguishing agent or the propellant. The tapered towards the top Container something, the remaining opening is tightly closed by a cap made of sheet metal. On this cap an attachment made of plastic is attached, which clamps the cap from the outside in the manner of a cylinder includes. The cylinder-like part of the attachment has incisions that run in the axial direction

aienen to increase the elasticity of the cylinder part, so that this can be placed more easily on the cap.

An axially displaceable pin is arranged in the center of the attachment, which has a push button at its upper end and is designed as a needle point at its lower end. To the Commissioning the fire extinguisher is pierced with this pin, the cap, so that then under pressure in the Extinguishing agent located in the container can escape to the outside through flow channels provided in the attachment.

After using the fire extinguisher, the attachment is removed and can be placed on a replacement container that has not yet been used will. The used container is sent away as a one-way container.
