Definitions

  • the present invention relates to a connection device for connecting a container containing a powder / granulate product to a device.
  • Connection devices for connecting containers which contain products in powder / granular form are generally known.
  • connection devices of this type the containers are usually connected by clamping a hose-shaped outlet of the container or a separate film tube provided for the connection and attached to the container to the connection device.
  • the powder / granulate product is then transferred via the tubular outlet or the film tube, i.e. H. either filled into the container or emptied from it.
  • a user After transferring the product, a user ties the tubular outlet or the film tube twice and then cuts it. The remainder of the film remaining on the connection device must be removed when a further container is reconnected. This is done, for example, via special lateral interventions provided for this purpose.
  • the explained process prevents a user with the product or - vice versa - the product from coming into contact with the outside environment, and is therefore particularly suitable for cases in which hazardous products must be handled or cross-contamination must be prevented.
  • the patent document EP 1 958 900 A2 shows, for example, a connection device that avoids such contamination.
  • the sketched connection of the container requires, on the one hand, a series of manipulations that determine the number of manageable, i.e. Limit the containers to be emptied or filled per unit of time downwards, and on the other hand generates waste in the form of separated film residues that have to be specially disposed of due to contact with the product.
  • the object of the present invention is to create a connection device for connecting a container containing a powder / granulate product to a device which enables containers to be handled quickly and without contamination.
  • connection device according to patent claim 1.
  • Further preferred embodiments are the subject of the dependent claims.
  • a connection device for connecting a container containing a powder / granular product to a device includes a base body which defines a connection opening to / into which the container is intended to be connected from an external environment with a transfer section which is intended for a removal and / or introduction of the powder / granular product from / into the container can be opened and closed again by a user.
  • Said transfer section is, for example, the upper section of a barrel on which a lid of the barrel rests, wherein the lid can be removed from the upper section of the barrel or placed on the upper section of the barrel for opening and closing the barrel.
  • the transfer section can be a tubular outlet of a container such as a big bag.

According to the invention, this applies both in a state in which the transfer section is guided to / into the connection opening and in a state in which the transfer section is not guided to / into the connection opening. In other words, in both states in which the container is connected or removed from the connection device or the connection opening, the connection device prevents the escape of particles or, after removal of the container, the escape of residues of the product.
  • the base body has an opening which is on a side facing away from the connection opening.
  • the base body defines a passage into which the transfer section of the container can be introduced through the connection opening. After introducing the transfer section of the container, the user can open the container, which can be done for example by manual intervention from the side facing away from the container.
