- an absolutely environmentally insulated docking device 96 is obtained, with which any bulk goods, as in FIG. 4 represented in fixed or transportable containers 116 can be transferred.
- the lever arms 106 and 108 are actuated in such a way that the first and second Conseinhei ⁇ th 102 and 104 are moved towards each other.
- the first and second closure strips of the first and second coupling closure 1 and 1 ' move uniformly away from each other opening both the flexible bag 90 and the flexible Um Scholl ⁇ hose 94.
- On the outer sides of the cheek body of the closure strips are in turn biegelastician Ledges 200 and 200 ', which are held with their opposite ends in Halte ⁇ ments that are part of the bearing elements.
- the docking device according to the invention can continue to be used without contamination, without the need for additional cleaning steps.
- the removal of the docking device according to the invention from the holding device 100 is just as simple as its instal lation.
- the coupling closures 1 and 1 ' can be easily separated from each other, in each case closed, so that even after loading or refilling a contamination of the environment as well as the transfilled products is not to be feared ,
- FIG. 5a shows a container 300 according to the invention for fine dosing of, in particular, powdered or granular bulk material.
- This flexible container 300 comprises a Be fiscaler ⁇ body 302 and a tapered towards the outlet section 304.
- This section 304 follows, interrupted by the second coupling closure 312 of the conveyor 310, at the opening end 306 environmentally sealed a first inventive coupling closure 308 is attached.
- the container body 302 is thus followed by a hose-like conveying means 310, which is regularly narrower than the bag body 302.
- the bag body for example, can be placed headfirst on dosing jaws 314 in such an embodiment for finely dosed emptying, by means of which the conveying means 310 protrudes.
- a second coupling device 312 is mounted for the fine metering of the bulk material to be filled.
- this coupling closure can simply be put on or pulled onto the conveying means 310 from the outside, so that it is the same encloses.
- the closure strips or the cheek body of this second coupling closure 312 are adhesively bonded to the outer wall of the conveying means, for example, when conveying means 310 and container body 302 are present in one piece.
- container body 302 and conveyor 310 as separate components to the second coupling closure 312, in which case the opening edge 310 of the container body 302 is preferably to the upper portion of the closure strips, especially the insides of the cheeks, and the first opening 318 of the conveyor 310, in particular circumferentially, with the lower portion of the closure strips of the second coupling closure 312, in particular the inner sides of the cheek body of the first and second closure strips, in particular environmentally sealed, connected.
- Ausgestal ⁇ tion sections of the inner sides of opposing cheek body of the second coupling closure 312 can come into direct contact with each other. It has been found that if such a direct contact of the inner sides of the elastic cheeks of the second coupling closure 312 is permitted, a particularly effective fine metering of even very finely divided bulk materials succeeds.
- Figure 5b shows a particularly preferred embodiment of a one-piece container 300 in an intermediate manufacturing step.
- each recesses 320 and 322 are provided on the front and the back of the container, which are each dimensioned smaller than the cheeks of the first and saut ⁇ ter closure strip of the second coupling closure 312.
- the cheek bodies of the coupling closure then come to rest or are connected in an environmentally tight manner to the edge 328 surrounding the recess.
- the container to be filled (not shown) in turn has a coupling closure according to the invention which can be coupled with the first coupling closure 308 of the container 300 to form an environmental-proof docking device according to the invention.
- This docking operation is preferably carried out after the controlled to be emptied container 300 has been brought into a suitable emptying position, for example by means of suitable metering jaws 314.
- the second coupling closure 312 preferably remains closed, ie the inner sides of the cheeks of the first and second closure strips lie directly or indirectly, ie separated by the bag walls, sealingly against each other.
- the inner elastic segments of the cheek body protrude beyond the outer thermoplastic segment of the cheek body.
- the trained docking device is opened, so that the container is available for filling.
- the second coupling closure 312 is also pressurized, preferably by a pneumatic and in particular elektri ⁇ cal drive device so that bulk material can pass from the container body 302 gravity driven into the container to be filled.
- the filling process can be assisted by suitable devices, such as vibrators or activators.
- the filling speed can be varied. In most cases, a gap of only 1 to 2 mm is sufficient to undertake a fine dosing. The accuracy of the dosing can be increased again, especially with very finely divided bulk materials by using a vibrator.
- FIG. 6 shows an alternative embodiment of a metering container 400 according to the invention, comprising a container body 402 and a conveyor 410.
- a coupling closure 408 according to the invention.
- a second inventive coupling closure for fine metering of particular powdery bulk material is in the Ausu ⁇ insurance form shown in Figure 6 on a metering device 412 with at least one opening under lateral pressure and variable expanding outlet 414 in the form a Schlit ⁇ zes resorted.
- This metering device 412 is mounted on the inside of the conveying means 410 or in the transition of the container body 402 and conveying means 410.
- this metering device 412 By connecting this metering device 412 completely environmentally sealed to the conveyor 410 or its inner wall (in FIG. 6, for the sake of illustration, a fully circumferential, but not full-surface connection between the inner wall of the conveyor and the outside of the metering device is shown reproduced), for example, with an adhesive or by means of welding, it is ensured that bulk material only on the Aus ⁇ laß 414 of this metering device 412 by the conveyor 410 in the direction of the first Coupling closure 408 can get.
- the metering device 412 has not only a bending-axial disc 416 separating the passage of the conveying means 410 but also wall elements 418 extending away from this disc, in particular in the direction of the container body 402, which can be connected to the inner wall of the conveyor 410.
- This vor ⁇ preferably circumferential wall 418 then forms together with the substantially schei ⁇ benförmigen partition 416 a kind of pantry.
- this wall it is likewise possible for this wall to extend from the elastic disk 416 in the direction of the first opening end 406 of the conveying means 410 or both in the direction of the opening end 406 and in the direction of the container body 402.
