  • the present invention relates to coupling closures and docking devices containing these coupling closures. Furthermore, the invention relates to a flexible container and a hose containing the coupling closures according to the invention, the use of docking devices according to the invention for the environmentally sealed filling, decanting and emptying of containers and a method for environmentally sealed filling, decanting and emptying of containers.
  • Bulk or solid bulk materials are produced as intermediate or end products in a variety of processes and, unless supplied via piping systems to their final destination or destination, are to be transported and marketed in the form of containers of a specific size. Since some products have a very toxic effect on the human organism even in small amounts or react very sensitively with air or moisture, very high demands are placed on the environmental tightness when transferring such products, for example for further processing into intermediate or end products. In addition to avoiding contamination of the environment high demands are placed on the purity of the starting or intermediate products used regularly, especially in the processing industry, which is why a contamination by impurities from the outside at each point of the process and not only in the production and isolation of the starting materials is to be avoided.

  • these coupling closures can be designed such that, if they have been respectively coupled in the closed state, can be opened sequentially or preferably simultaneously.
  • coupling closures in the sense of the present invention are provided on openings of containers, containers or conveying means, such as hoses, and are connected to them, in particular tightly.
  • the container or the conveyor can be opened or closed and coupled with a container, container or conveyor, which is equipped with a corresponding coupling closure, to form a docking device.

  • the coupling closure according to the invention is particularly suitable for loading and / or reprecipitation of bulk material from flexible containers, for example plastic bags or sacks. Accordingly, in one embodiment, such a coupling closure already has a flexible bag or hose whose opening edge is connected to the first and second strip separately or in one piece.
  • the coupling closure can be both an integral part of a flexible bag, in particular in the region of the opening edge of this bag, as well as in retrospect with a bag reversibly or irreversibly connected.
  • the risk of contamination can preferably also be reduced by at least the inner side and / or the upper side of the first and / or second strip having or having at least sections an adhesive and / or adhesive layer.
  • the two first and second coupling closures according to the invention which are to be connected to one another, are dimensioned essentially identically, in order to enable environmentally sound coupling.
  • a particular advantage of the docking device according to the invention is also that two identical coupling closures according to the invention can be used.
  • the third and fourth closure elements of the first and second strip of the first coupling closure are designed to be complementary to each other.

  • the aforementioned docking devices can already be connected or connectable via their first and second coupling closures to at least one flexible container, hose or hose element.
  • flexible containers may be provided with at least one removal device, in particular in the form of a spoon or spatula, which is connected to the flexible container on the inside.
  • the present invention was thus based on the surprising realization that coupling elements with flexible closure strips are suitable for the environmentally sealed loading and transferring of bulk material from or into flexible containers, without taking restrictions on the container size or the opening area to have to.
  • the coupling closures according to the invention are accordingly suitable for all packaging sizes and can be connected reliably with coupling closures of the same type to environmentally sound docking devices without much effort.
  • the coupling closures and docking devices according to the invention are characterized by a very small number of components and can therefore be manufactured and assembled inexpensively. In this context, not only the manufacturing process, but also the maintenance of the coupling closures and docking devices according to the invention designed as little labor intensive and time consuming.
  • the coupling closures and docking devices according to the invention also represents that they must be kept under pretension neither in the open nor in the closed state, which, for example, when opening no component intrinsic resistance is overcome. This prevents rapid material fatigue and ensures long-term reliable handling with a permanently high level of environmental integrity.
  • FIG. 1 shows a coupling closure 1 according to the invention in a schematic cross-sectional view in the closed state.

  • the first closure element 10 located on the inner side 6 of the first strip which is configured in the form of a spring, engages in the second closure element 12, which is configured in the form of a groove, on the inner side 8 of the second strip 4.
  • the first and second closure elements 10 and 12 can be designed as desired, as long as they behave complementary in shape and size and ensure that the first and second strips 2 and 4 do not separate from each other without external force. Suitable clip, groove or rivet fasteners are known in the art.
  • the first and second closure elements 10 and 12 advantageously extend along the entire inner sides of the first and second strips 2 and 4.
