On the downstream end face 29 of the cap 17 is formed over the central opening 19 extending recess 30 which causes the diameter of the opening 19 in the region of the recess 30 is greater than the diameter of the opening 19 outside the recess 30. Die Deepening is for example the FIGS. 5 and 6 refer to. The extension of the diameter of the opening 19 of the cap 17 is also given for example by comparing the FIGS. 6 and 7 ,

The outer diameter of the fastening part 12 of the dispenser 11 in the region of the projections 27 of the webs 26 is smaller than the smallest diameter of the central opening 19 of the cap 17 in the region of the recess 30 with a small clearance. In the area outside the recess 30, the smallest diameter of As a result, the maximum outer diameter of the attachment part 12 of the dispenser 11 is approximately equal to or smaller than the maximum diameter of the central opening 19 of the cap 17.

In the in the FIGS. 3 to 7 illustrated mounting position of the dispenser 11 is inserted with its mounting portion 12 so in the central opening 19 of the cap 17 and placed on the valve nozzle 4 that the projections 27 of the webs 26 are directed to the recess 30 having edge portion of the opening 19. In this position, therefore, the dispenser can be passed unhindered through its opening 19 with its mounting area and placed on the valve nozzle 4.

After rotation of the dispenser about the longitudinal axis of the valve nozzle 4 from the previously described and in the FIGS. 3 to 7 shown mounting position in the in FIGS. 8 to 10 shown operating position engage the projections 27 of the webs 26 of the mounting portion 12 below the edge portions of the opening 19 with a smaller inner diameter, whereby the mounting portion 12 of the dispenser 11 is prevented from detaching from the valve nozzle 4 and simultaneous removal from the opening 19. The thus caused hold the dispenser 11 can be particularly the FIG. 9 remove.

Like from the Figures 10 and 12 shows the bayonet lock described above obstructs the tilting movement of the dispenser 11 from the mounting position (see FIG. 10 ) in the tilted position (see FIG. 12 ) Not. Even during the tilting movement and in the tilted position of the dispenser 11, the bayonet closure is retained by the projections 27 of the webs 26 of the attachment region 12 of the dispenser 11 engaging under the edge regions of the central opening 19 with a smaller inner diameter.

As continues from the FIGS. 6 and 7 As can be seen, two webs 31 are arranged on the upstream side of the projections 27 of the webs 26 of the mounting portion 12 of the dispenser 11, which extend upstream of the projections 27 and whose radially outer sides are inclined radially inwardly in the upstream direction. The webs 31 serve as insertion aids during insertion of the attachment region 12 of the dispenser 11 into the opening 19 of the cap 17.

Like from the FIGS. 6 and 7 Also, the webs 31 are disposed on the radially outer side of plate-shaped parts 32 which are integrally formed on the upstream side of the annular flange 20 of the mounting portion 12.

Between the annular flange 20 and the cylinder jacket-shaped portion 25 of the mounting portion 12 of the dispenser 11 are also at an angle of 90 ° the projections 27 on the webs 26 upstream ribs 33 are arranged, which also serve as insertion aids during insertion of the mounting portion 12 in the region of the smaller diameter of the opening 19 outside the recess 30, since their radially outer edges are inclined in the upstream direction radially inwardly , The ribs 33 also serve to reinforce the seating of the annular flange 12 on the attachment portion 12 of the dispenser 11.

Like the plan views according to the Figures 3 . 5 . 8th and 11 show, the recess 30 is substantially mirror-symmetrical to the axial to the opening 19 and perpendicular to the plane in which the tilting movement of the dispenser 11 takes place, extending plane. In addition, the recess 30 is also formed substantially mirror-symmetrically to the plane in which the tilting movement of the dispenser 11 takes place. The recess 30 extends in the radial direction over the downstream facing end face 29 of the cap 17 away. The edges of the recess 30 pointing in the circumferential direction of the opening 19 extend essentially in the parallel direction.

Such as from the sectional views of FIGS. 7 and 10 As can be seen, the conical constriction 28 having region of the edge of the opening 19 of the cap 17 is provided at its upstream end with a circumferentially extending undercut 34. The undercut 34 serves that, as in FIG. 12 shown, the radially outer edge region of the annular flange 20 of the attachment portion 12 in the tilted position of the dispenser 11 engages under the conical constriction 28 having edge portion of the opening 19 and thus with the inner portion of the opening 19 positively against removal of the dispenser 11 in the axial Direction of tilting cooperates.
