Definitions

the invention relates to a fire extinguisher with a container for holding extinguishing agents such as, extinguishing powder, water, water-foam mixture, halon or the like, with a container volume between 1 and 15 liters and a working pressure on the extinguishing agent of 5 to 25 bar , and a valve to discharge the extinguishing agent.
extinguishing agents such as, extinguishing powder, water, water-foam mixture, halon or the like
Fire extinguishers of this type are used as mobile or semi-stationary extinguishers, the containers being made from sheet steel or aluminum.
the invention has for its object to provide a container for fire extinguishers that is easier to handle, is corrosion-resistant and at the same time can be manufactured cheaper.
the container consists of a plastic and the container jacket is made from a molded article according to the so-called stretch blow molding process.
the molding made of PETP, polyacrylonitrile or the like can be injection molded.
the injection molded, hollow body-like molding is closed at one end and provided with a container neck at the other end. This is clamped in a blow molding machine and the remaining part of the molded part is blown into a mold, creating the container coat arises.
the material stretches, preferably in a ratio of 1: 6 to 1:12, and solidifies at the same time. This solidification allows the plastic container to be operated as a fire extinguisher with a high working pressure acting on the extinguishing agent. This high working pressure is required to quickly and safely drive the extinguishing agent out of the container in the event of a fire.
plastic fire extinguishers could not be manufactured economically for the required pressure and temperature range.
a plastic fire extinguisher according to the invention has the advantage over the metal fire extinguisher that it is lighter and therefore easier to handle. This is particularly advantageous for mobile hand-held extinguishers. Furthermore, the extinguisher made of plastic has a longer shelf life because it is more corrosion-resistant than the previous metal extinguishers. Another advantage of the extinguisher according to the invention can be seen in the fact that its production costs are significantly lower compared to the previous extinguishers. This price advantage may permit use as a disposable extinguisher. This means that an exchange takes place instead of the statutory inspections, filling controls and refills.
the fire extinguisher container according to the invention also has an optical advantage.
the container jacket can be used without difficulty simplest means can be brought into any shape.
the container can thus have a shape which is typical for the applicant and which acts like a design and is consequently effective in advertising.
the high manufacturing costs of the metal fire extinguisher containers only allowed a typical shape to a limited extent.
a molded article By means of the stretch blow molding process, a molded article can be used, to which a threaded connection piece is attached, so that a plastic valve can be attached and the entire fire extinguisher is made of plastic, with all the advantages mentioned above.
the lower part is designed as a spherical base and is provided with a base part to ensure the fire extinguisher's stability. Because of the measure according to the invention, the container jacket and the container base can be injection molded from one part. This also reduces the manufacturing and assembly costs.
the stretch blow molding process allows parts of the container casing to be made transparent.
a filling control for the extinguishing agent can thus be created with the simplest means.
Fire extinguishers are used as boost pressure extinguishers or as permanent pressure extinguishers.
the fire extinguishing agent is overlaid with a gas under pressure, which expels the extinguishing agent when the extinguishing valve is opened.
the boost pressure fire extinguisher has the advantage that there is no pressure loss due to an existing permeability.
An embodiment of the invention is shown using a supercharger fire extinguisher with an internal pressure source and is described in more detail below.
the fire extinguisher 1 consists of a container 2 and a valve 3.
the container 2 is made from a blank, not shown, in the stretch blow molding process.
the molding has a container neck 4 onto which a threaded connector 5 is sprayed.
the container neck 4 is clamped in the stretch blow molding machine, not shown, and thus the container jacket 6 is produced in the stretch blow molding process, the thickness of the container jacket 6 being considerably thinner than the original thickness of the molding.
the strengthening of the container casing 6 is increased by the stretching process to such an extent that the working pressure required for proper operation can be absorbed by the container casing 6.
the container bottom is produced simultaneously with the container jacket 6 in the stretch blow molding process. Consequently, parts 6 and 7 are made in one piece.
the valve 3 preferably has a valve socket 8 with Internal thread 6, which can be screwed onto the external thread of the connector 5.
a valve tappet 12 can be actuated with a valve lever 9, which opens a pressure bottle 11 and drives out the extinguishing agent located within the container jacket 6 via the outlet nozzle 10.
a valve insert 14 is connected to the valve stub 8 and on the one hand guides the valve tappet 12 and on the other hand it carries the pressure bottle 11 and a riser pipe 13.
