DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0052] FIG. 1 shows schematically an exemplary embodiment of the removal system 1 according to the invention.

[0053] The removal system 1 comprises an extraction head 2, that may be placed onto an opening of a bottle 3, which contains a fluid 4. On the extraction head 2, a tube 5 is mounted that runs from the extraction head 2 into the interior cavity of the bottle 3.

[0054] The extraction head 2 is further connected to a pump 7 via a line 6. Fluid 4 is pumped out of the bottle 3 by means of the pump 7. The fluid 4 is removed from the bottle 3 via the tube 5 and then fed into the line 6.

[0055] FIGS. 2-4 show an exemplary embodiment of the extraction head 2 according to the invention. The extraction head 2 has a closing means 8 in the form of a screw top, by means of which the extraction head 2 may be secured on the opening of a bottle 3. The screw top has an internal thread 9 that may be screwed onto a thread on the opening of the bottle 3. Due to the screw top of the extraction head 2, a leak-tight seal of the opening of the bottle 3 results.

[0056] Furthermore, the extraction head 2 has a head piece 10. At the upper end of the head piece 10, a connection 11 is provided at which the line 6 leading to the pump 7 may be connected. The connection 11 is secured by a check valve 12. The check valve 12 prevents fluid from escaping from the line 6. Furthermore, in the head piece 10, a ball valve 13 is provided, by means of which an air and pressure equalization is effected in the bottle 3.

[0057] A guide channel 14 opens out at the bottom of the head piece 10, which guide channel 14 projects into a central recess in the closing means 8, wherein the lower end of the guide channel 14 is secured with fastening means 15 within the closing means 8. The guide channel 14 is hollow and cylindrical in form.

[0058] The head piece 10 is movable relative to the screw top forming the closing means 8, an actuation mechanism being formed in this case.

[0059] A spring 16 is arranged between the head piece 10 and the screw top. The head piece 10 is held at a distance from the top of the locking means 8 (FIG. 2) by the spring force of the spring 16. If a user actuates the actuation mechanism formed in this manner, he presses on the upper end of the head piece 10 and presses it down, until the bottom of the head piece 10 lies on the top of the closing means 8 (FIGS. 3 and 4).

[0060] FIG. 2 shows the extraction head 2 with a non-actuated actuation mechanism. The tube 5 is mounted in the inner cavity of the guide channel 14 and held in position there with locking means.

[0061] As is evident from FIGS. 2-4, the upper end of the tube 5, which is insertable into the guide channel 14, is provided with a sleeve 17 that has a circumferential groove 18 extending in circumferential direction.

[0062] The locking means are formed by balls 19 that are guided in bore holes 20 within the guide channel 14. In the present case, four identical bore holes 20 are provided in a plane perpendicular to the longitudinal axis of the guide channel 14, which bore holes 20 are respectively arranged offset by 90 to one another in circumferential direction. The bore holes 20 extend in radial direction within the guide channel 14. A ball 19 is guided in each bore hole 20, whereby all balls 19 are identical in form. The balls 19 are guided in the respective bore holes 20 with little play.

[0063] The diameters of the bore holes 20 are somewhat constricted in the region of the opening out into the guide channel 14, i.e. are somewhat smaller than the ball diameter, such that the balls 19 are prevented from falling out into the empty guide channel 14.

[0064] As is evident from FIGS. 2-4, a projection 21 is provided at the upper edge of the wall element of the closing means 8 that delimits the recess, which projection 21 runs circumferentially in circumferential direction and represents a narrowing of the recess into which the guide channel 14 projects. This projection 21 forms a positioning means, FIG. 2 showing the closing means 8 and the positioning means in a locking position. This locking position is adopted when the actuation mechanism is not actuated and the spring 16 holds the head piece 10 at a distance from the closing means 8. The projection 21 forming the positioning means then lies, as shown in FIG. 2, in the region of the bore holes 20. The projection 21 therefore pushes the balls 19 in the bore holes 20 in the direction of the interior cavity of the guide channel 14, such that in a locking position, the balls 19 are pressed against the groove 18 in the sleeve 17 of the tube 5 with a pressing force, by means of which the tube 5 is secured within the guide channel 14.

[0065] When the actuation mechanism is actuated as shown in FIG. 3, the head piece 10 is pressed against the screw top forming the closing means 8 and the guide channel 14 is pushed further into the recess of the screw top. Therefore, the closing means 8 and with it, the projection 21, are moved from the locking position into a release position. In this release position, the projection 21 lies above the bore holes 20. The balls 19 are therefore in a released position and are therefore no longer pressed against the tube 5 by means of the projection 21, i.e. the tube 5 is no longer held securely inside the guide channel 14. Therefore, due to gravity, the tube 5 falls out of the guide channel 14 (FIG. 4) and falls into the bottle 3.

[0066] To empty the bottle 3, the extraction head 2 is fastened to the bottle 3. The actuation mechanism is not actuated and the tube 5 is held securely inside the guide channel 14 (FIG. 2). The bottle 3 is then emptied by means of the pump 7. Once the bottle 3 is empty, the actuation mechanism is actuated and the tube 5 inside the guide channel 14 is released (FIG. 3), such that the tube 5 falls into the empty bottle 3 and may be disposed of.

[0067] If the extraction head 2 is to be used for removing fluid 4 from another bottle 3, first a new tube 5 is fastened inside the guide channel 14 of the extraction head 2.

[0068] To do so, a user actuates the actuation mechanism and then slides the tube 5 into the guide channel 14. Then the user releases the head piece 10, such that the head piece 10 is raised up from the closing means 8 by the spring force of the spring 16. The closing means 8, with its projection 21, is then moved into the locking position, by means of which the tube 5 is held securely inside the guide channel 14.

[0069] The assembly formed in this manner may then be placed onto the other bottle 3 for removing fluid 4.
