Definitions
- the invention relates to a container for flowable Media, especially shaped by blow molding Plastic container, with a reference to the flowable medium connected ventilation device in a round collar opening of the container ceiling, with a cylindrical central body with upper central body chamber and lower central body chamber and with a bottom, wherein the central body inserted into the collar opening and under Interposition of a sealing ring with a on the central body molded ring flange on the collar of the collar opening is attached, with a filter substance that in the Central body is arranged, and with a flat lid, the ring flange of the central body with collar elements comprises, the cylindrical central body one at the bottom of the central body attached to the container interior Protective cap protruding from the floor with at least one Passage, and wherein the flat cover between the Has slot elements for ventilation ventilation.
- the flowable medium can be a Trade liquid with high or low viscosity, it can also be a flowable, fine-grained or act powdery medium.
- Aeration device means a device that builds up pressure in the container prevented as well as the development of a negative pressure.
- a Pressure build-up or a negative pressure can for example arise because the flowable introduced into the container Medium changes in volume under the influence of temperature changed, so to speak "breathes".
- "Between the fret elements” means that the all-round covenant, forming Slot spaces is divided into fret elements and that itself this slot spaces between the collar elements are located.
- containers are known in the lower Area of a side face a removal opening and in the Have a ventilation device.
- a ventilation device from a small diameter hole in a cover, the one on the collar of a corresponding opening is screwed on.
- the invention has for its object such To create containers, which ensures that on the one hand finely divided pollutants or water the air can enter the container, on the other hand the filter substance is protected from the flowable media becomes.
- the invention proposes generic container for flowable media, especially molded containers by way of blow molding made of plastic, before that the lower central body chamber via a check valve with the upper one Central body chamber is connected, and that the Filter substance is located in the upper central body chamber.
- the cylindrical central body, the Protective cap and the flat lid molded from plastic be.
- the association can be cohesive or form-fitting, e.g. B. by welding or locking, respectively.
- the passage can be a recess or a bore.
- the invention is based on the knowledge that in a Ventilation device consisting of the components described Central body, protective cap and flat lid is constructed, on the one hand there is a room in which filter materials can be accommodated, for example in the form a cartridge can be inserted, what the penetration of finely divided impurities in the interior of the container while "breathing" the filled flowable medium prevented.
- the flat lid protects the ventilation device overall and works at the same time as a safety device against uncontrolled opening.
- the flat flat lid can have recesses on the top Have insertion of an operating tool.
- the Ventilation device can be easily designed so that in Inside the container a slight and controlled Pressure build-up or a minor and controlled Set negative pressure.
- the invention recommends that the bottom of the central body has openings on which a flow resistance fleece is put on. It can but also the central body at the top of such Flow resistance fleece must be covered.
- the Ventilation device the specified function. Does he have A lower discharge opening with a container Closure body, e.g. B. in the form of a tap, so can Ventilation device for an air supply at the outlet of the medium can be set up via the discharge opening. It In this case, the openings described are recommended to be provided with a sufficiently large diameter and the To leave or to remove filter substance in the central body remove.
- the container 1 shown in the figures is for flowable media determines and consists of plastic. He is preferably molded by blow molding. He is with a closed with respect to the flowable medium Ventilation device 2 provided directly or with Using a screw cap in a round collar opening 3 of the container 1 is housed.
- FIGS. 2 and 3 One notices a cylindrical central body 4, which in the Collar opening 3 is inserted, a bottom 5 with at least has a filter opening 6 and with interposition a sealing ring 7 with an integrally formed ring flange 8 is placed on the collar 9 of the collar opening 3.
- Central body 4 is a filter substance 10, for example in the form of a filter cartridge.
- Under the Central body 4 is located towards the interior of the container convex, spherical or conical Protective cap 11. In the exemplary embodiment, it is conical executed. It is at the bottom 5 of the central body 4 attached.
- this protective cap has 11 as a passage 12 a bore. Also is a level Flat lid 13 is provided, the 14 with collar elements Ring flange 8 of the central body 4 includes and in the area between the collar elements 14 slot spaces 15 for the Has ventilation.
- the cylindrical central body 4, the protective cap 11 and the flat cover 13 are united by welding.
- the flat cover 13 is with the help of opening protection elements 16, which when opening the flat cover 13 break, attached to the collar 9 of the collar opening 3.
- the protective cap 11 and Flat lid 13 are made of plastic.
- the flat cover 13 has recesses 17 on the upper side for inserting one Tool. It was indicated in Fig. 2 on the right that one omit the filter substance and apply it to the central body 4 can put on a cover 18.
- a flow resistance fleece could also be placed on the filter opening 6. In this way can be achieved that a permissible internal pressure in the Container builds up or a permissible negative pressure becomes sets. If you enlarge the described openings and if the filter substance is left out, the ventilation device can 2 also for the air supply at one Leakage of the medium from the container 1 via a lower one Drain opening 19 function.
- 4 and 5 is the Ventilation device inserted into a screw cap 21, which is screwed onto the collar of the collar opening.
- the Opening protection device 16 is made of sheet metal or foil molded cap attached to the flat lid 13.
- 4 and 5 are the reference numerals already explained have been entered because the embodiment according to FIGS. 4 and 5 in this respect with the embodiment according to FIG. 2 and 3 matches.
- As passage 12 are special Recesses provided. The arrangement is however in 4 and 5 so taken that the Central body 4 to the interior of the container via the floor 5 protrudes so that the central body 4 an upper Central body chamber 4a, in which the filter substance 10 is arranged, as well as a lower central body chamber 4b has, which via a check valve 20 with the upper Central body chamber is connected.
- the protective cap 11 is arranged in the area below the check valve 20 and welded to the central body.
