Definitions

  • the invention relates to a container for flowable media, in particular a blow molded plastic container, - with a closed with respect to the flowable medium ventilation device in a round collar opening of the container ceiling.
  • the flowable medium can be a liquid with a high or low viscosity, but it can also be a flowable fine-grained or powdery medium.
  • Aeration device means a device that prevents pressure build-up in the container as well as the creation of a negative pressure.
  • a pressure purchase structure or a vacuum can arise, for example, because the flowable medium filled into the container changes in volume under the influence of the temperature, that is to say "breathes".
  • Containers with such a ventilation device are also used for adhesives.
  • Containers of the basic structure described above which have a removal opening in the lower region of a side surface and a ventilation device in the top surface.
  • a ventilation device consists of a small diameter bore in a cover which is screwed onto the collar of a corresponding opening. It cannot be prevented that pollutants or water penetrate into the interior of the container when the container is "breathing”.
  • the invention has for its object to provide a plastic container for flowable media, which is provided with a ventilation device, which at the same time ensures that finely divided pollutants or water can not penetrate into the container.
  • the subject of the invention is a container for flowable media, in particular by plastic blow molding, with a ventilation device closed with respect to the flowable medium in a round collar opening of the container top with
  • a protective cap which is attached to the bottom of the central body and has at least one passage
  • a flat cover which, with collar elements, encompasses and is united with the ring flange of the central body and has slot spaces for ventilation in the region between the collar elements, wherein the cylindrical central body, the protective cap and the flat cover are combined with one another and the flat cover is fastened with the aid of an opening protection device which breaks when the flat cover is opened.
  • the cylindrical central body, the protective cap and the flat cover can be molded from plastic.
  • the union can take place cohesively or positively, for example by welding or locking.
  • the bottom has at least one filter opening.
  • the passage can be a recess or a bore.
  • the invention is based on the finding that, in the case of a ventilation device which is constructed from the described central body, protective cap and flat cover, on the one hand a space is created in which filter materials can be accommodated, for example in the form of a cartridge, which can be used Prevention of fine-particle contamination into the interior of the container when the filled flowable medium "breathes" is prevented.
  • the flat lid protects the ventilation device as a whole and at the same time functions as a safety device against uncontrolled opening.
  • the flat flat cover can have depressions on the upper side for inserting an actuating tool.
  • the ventilation device can easily be designed such that a slight and controlled pressure build-up or a slight and controlled negative pressure occur in the interior of the container.
  • the invention recommends that the bottom of the central body has openings on which a flow resistance fleece is placed.
  • the top of the central body can also be covered by such a flow resistance fleece.
  • the ventilation device fulfills the stated function.
  • the container has a lower emptying opening with a closure body, e.g. B. in the form of a tap, the ventilation device can be set up for an air supply when the medium runs out through the discharge opening. In this case it is advisable to provide the openings described with a sufficiently large diameter and to remove or remove the filter substance in the central body.
  • the container 1 shown in the figures is intended for flowable media and consists of plastic. It is preferably shaped by blow molding. It is provided with a ventilation device 2 which is closed with respect to the flowable medium and which is accommodated directly or with the aid of a screw cap in a round collar opening 3 of the container 1.
  • a ventilation device 2 which is closed with respect to the flowable medium and which is accommodated directly or with the aid of a screw cap in a round collar opening 3 of the container 1.
  • FIGS. 2 and 3 A cylindrical central body 4 can be seen, which is inserted into the collar opening 3, has a bottom 5 with at least one filter opening 6 and is placed on the collar 9 of the collar opening 3 with the interposition of a sealing ring 7 with an integrally formed ring flange 8.
  • a filter substance 10, for example in the form of a filter cartridge, is accommodated in the central body 4.
  • a spherical cap or conical protective cap 11 convex towards the interior of the container. In the exemplary embodiment, it is designed conical. It is attached to the bottom 5 of the central body 4. At least at its lowest point, this protective cap 11 has a bore as a passage 12.
  • a flat flat cover 13 is provided which, with collar elements 14, encompasses the ring flange 8 of the central body 4 and in the region between the collar elements 14 has slot spaces 15 for ventilation.
  • the cylindrical central body 4, the protective cap 11 and the flat cover 13 are joined together by welding.
  • the flat cover 13 is fastened to the collar 9 of the collar opening 3 by means of opening protection elements 16 which break when the flat cover 13 is opened.
  • the cylindrical central body 4, the protective cap 11 and the flat cover 13 are made of plastic.
  • the flat cover 13 has recesses 17 on the upper side for inserting a tool. It was indicated in FIG. 2 on the right that the filter substance can be omitted and a cover 18 can be placed on the central body 4.
  • a flow resistance fleece could be placed on the central body 4.
  • a flow resistance fleece could also be placed on the filter opening 6. In this way it can be achieved that a permissible internal pressure builds up in the container or that a permissible negative pressure is established. If the openings described are enlarged and the filter substance is left out, the ventilation device 2 can also function for the air supply when the medium runs out of the container 1 via a lower emptying opening 19.
  • the ventilation device is inserted into a screw cap 21 which is screwed onto the collar of the collar opening.
  • the opening protection device 16 is a cap which is formed from sheet metal or film and is fastened to the flat cover 13.
  • the central body 4 protrudes toward the container interior over the bottom 5, so that the central body 4 has an upper central body chamber 4a, in which the filter substance 10 is arranged, and a has lower central body chamber 4b, which is connected to the upper central body chamber via a check valve 20.
  • the protective cap 11 is arranged in the area below the check valve 20 and welded to the central body.
