DETAILED DESCRIPTION OF THE INVENTION Such a coupling device applies a predetermined fluid, only on the container, which supplies the exhalation fluid outside the container and recommends coding the plug coupling therein. . Uses for this purpose are protrusions and recesses, which cooperate with these protrusions to ensure only certain coupling devices that fit on certain insertions of the container. The insert is placed by the fluid supplier.

A drawback of existing devices is that the different components are placed separately from each other, which is still an error in practice.

The present invention aims at obviating the above-mentioned drawbacks and is characterized in that the clamping member is connected so as not to slide in the axial direction of the plug, but relatively freely rotatably there. Provides this effect of the device,
The coupling means in the insert is spaced at the bottom to form a chamber, the recess being located above the chamber of the insert,
The stopper is a downwardly extending portion of the clamp member and is located at a distance below the coupling means.

Due to the rotatable connection of the clamping member to the plug, axial displacement can be eliminated and the particular arrangement of the cooperation of the plug and the recess makes it possible to prevent an incorrect connection as described above. . The stopper, including the stopper assembly, is nevertheless free to turn with respect to the insert.

Other characteristics of the invention are explained further in the drawing representations in the examples below. The attached figure shows a perspective view of the device with partially separated parts.

Reference numeral 1 shown in the drawing is a fluid container,
Only the top wall is shown schematically. The depression in the upper wall is
An opening 2 for connecting a threaded plug hole 3. An insert 4 which provides a synergistic action with the screw 5 is arranged in this plug hole. The insert 4 includes a passage opening 6 and a second orifice 7, the operation and function of which will be described further below.
Between the screw 9 and the bottom of the space 10, such that the screw 9 is located in the cylindrical inner part at a distance from the bottom 8 of the insert,
Pass through freely and form a chamber for the following purposes:

Inside the insert 4 in which the plug 11 is arranged, a plug connection 12 for the discharge tube is provided, through which a hole 13 extends from the top to the bottom.

The plug 11 includes a recess 14 such as a groove on its outer peripheral surface.

An outwardly facing flange 15 is located at the lower end.

A clamp piece 16 is provided around the plug 11 with an annular flange 17 in the annular inner part which fits into the annular groove 14 of the plug 11. Annular flange 1
Since the distance between 7 and the underside of the cylindrical portion 19 of the clamp piece 16 is separated, the latter (underside of the cylindrical portion 19) end is straight on the protruding flange 15 of the plug.

As a result of the connection formed by the groove 14 and the protruding flange 17, the clamp piece 16 is rotatable relative to the plug 11 in the direction of the arrow P1 but not axially slidable. Once mounted, the clamp piece 16 remains fixed on the plug 11.

According to the invention, the projections 20, 21 are arranged and arranged on the cylindrical outer wall of the clamp piece 16 under the screw 22 arranged therein.

Furthermore, for the screw 9, the distance between the two recesses 23, 24 arranged in the inner part of the insert 4 corresponds to the distance between the projections 20, 21. Recesses 23, 24
Also corresponds to the associated width of the projections 20,21.

Due to the placement of the plug 11 in the insert 4,
The plug 11 and clamp piece 16 assembly is inserted into the cylindrical opening of the insert 4. For this purpose, the projections 20,
The clamp piece 16 is rotated in the direction of the arrow P1 by turning the clamp ring 25 upward so that 21 comes to the positions of the recesses 23 and 24 on the opposite end side. The assembly can then be conveyed downwards in the direction of arrow P2 , the projections 20, 21 moving below the screw 9 into the space 10 of the insert 4.

The clamp piece 16 is consequently free to rotate with respect to the plug 11 and the insert 4. The further rotation causes the screw 22 to engage the screw 9, after which the clamp piece 16 can be screwed firmly into the insert 4. The plug 11 is thus fixed and clamped in the discharge hole (plug hole 3) of the fluid container 1.

Prior to the final clamping, the plug 11 is free to continue to rotate. Therefore, reaction or twist does not occur on the discharge pipe connected to the plug connector 12 . A further option is a non-rotating valve 30 in the passage of the stopper assembly 12 of the stopper 11.

The valve 30 is pressed downward by the compression spring 31 and partitions the opening of the stopper 11 downward. During placement, the rear portion 33 of the valve 30 approaches the passage 34 of the insert 4 against the stop 34, in which the valve is lifted from its seat by the placement of the plug 11.

It should be noted that the opening 13 of the plug 11 communicates with the hole 7 via the annular groove 34 of the insert 4 for ventilation purposes. A suitable seal ring 35 ensures the separation between the liquid passage and the vent through the plug.

It is further noted that other embodiments are possible within the scope of the invention. The positions of the projections 20, 21 and the associated recesses 23, 24 are of course taken as examples, and quite different codings can apply different arrangements and widths of the projections 20, 21.
