Withdrawal system

1 . A dispensing system for a container, the dispensing system comprising:

a dip tube,

wherein the dip tube is fastened to an inner side of a pipe-shaped lug of the container,

wherein the dip tube includes a dispensing opening closeable by a dip tube closure,

wherein a dispense head configured to dispense liquid form the container to supply the liquid into the container is attachable to the dip tube when the dip tube closure is removed,

wherein the dip tube includes has a release safeguard, which contacts the outer side of the pipe-shaped lug with a clamping pressure,

wherein the release safeguard forms a conductive connection between the dip tube which includes dissipation-capable material, and the outer side of the container, which outer side includes dissipation-capable material,

wherein the dip tube is mounted in the container in an electrically insulated manner, wherein the release safeguard creates an electrically conductive connection between the dip tube head of the dip tube and the conductive outer side of the container so that electrostatic charges of the liquid in the container are dissipatable, and

wherein a dissipation capable material is a material whose electrical conductivity is large enough to allow electric charges to be dissipated, and

wherein the dip tube includes an outer thread that is threadable into an inner thread of the pipe-shaped lug, and

wherein the release safeguard provides safety against rotational opening of a screw connection between the outer thread of the dip tube and the inner thread of the pipe shaped lug by a friction locking engagement of radially inward protruding engagement elements arranged on a radially inward facing side wall of the dip tube,

wherein the radially inward protruding engagement elements are compressed in a radial direction by a contact with a radial outside of the pipe shaped lug and provide the electrically conductive connection between the dip tube and the outer side of the container.

2 . The dispensing system according to claim 1 , wherein the dip tube includes an inner thread into which the dip tube closure is threadable.

3 . The dispensing system according to claim 1 ,

wherein the dip tube includes has a dip tube head mounted in the pipe-shaped lug, and

wherein a mushroom-shaped lug attaches to the dip tube head, the side wall of the mushroom-shaped lug lying opposite the outer side of the pipe-shaped lug.

4 . The dispensing system according to claim 3 , characterized in that the dip tube head is designed with rotational symmetry and has a widening on its top, and the hollow-cylindrically shaped side wall opens out on a bottom of the widening.

5 . The dispensing system according to claim 1 , wherein the engagement elements are formed by elastic elements fastened on the inner side of the side wall.

6 . The dispensing system according to claim 5 , wherein the engagement elements are formed by hook-shaped elements protruding from the inner side of the side wall.

7 . The dispensing system according to claim 6 , wherein the hook-shaped elements are spring elastic.

8 . The dispensing system according to claim 6 , wherein the outer contour of the pipe-shaped lug is adapted to the contours of the hook-shaped elements.

9 . The dispensing system according to claim 8 , the hook-shaped elements provide the safety against the rotational opening of the screw connection.

10 . The dispensing system according to claim 4 , wherein a seal is fastened on the bottom of the widening of the dip tube head, wherein the seal engages a top of the pipe-shaped lug.

11 . The dispensing system according to claim 10 , wherein the seal is made from electrically insulating material.

12 . The dispensing system according to claim 1 , wherein the container includes a multilayer wall with an outer layer including dissipation-capable material and an inner layer made from an electrically insulating material.

13 . The dispensing system according to claim 1 , wherein the dissipation-capable material is a plastic or metallic material.

14 . The dispensing system according to claim 1 , wherein the inner layer includes consists of a plastic material.

15 . The dispensing system according to claim 1 , wherein the radially inward protruding engagement elements are integrally configured in one piece with the dip tube.
