The dispenser 11 is provided with an inner channel 13 which opens upstream into a tubular portion 14. The outer diameter of the tubular portion 14 decreases toward the upstream end so as to be insertable and press-fitted into the downstream tubular end portion of the valve nozzle 4

is fastened.

Furthermore, the attachment portion 12 of the dispenser 11 is provided with a conical portion 15 which widens to its upstream end. Between the conical

Region 15 and the tubular portion 14 of the

Fixing portion 12 of the dispenser 11 is provided an annular groove 16 open to its upstream end, in which the downstream projecting tubular end portion of the valve nozzle 4 is press-fitted.

With a cap 17 is designated, which is fixed to the beaded edge 6 of the container 1. The cap 17 has at its outer periphery an external thread 18, on which a

Commercially available spray gun with an arranged in the region of its upstream end internal thread

The undercut is formed in the embodiment considered by a cylindrical extension of the opening 19. The opening 19 thus includes one at its downstream end

arranged cylindrical area, which extends over a shoulder-shaped area 22 in the extended

cylindrical area 21 passes. The shoulder-shaped portion 22 is shaped so that during the tilting movement of the dispenser 11 from the axial alignment shown in Figure 1 relative to the cap 17 and the container 1 in the tilted position shown in Figure 2, the flange 20 with a very small clearance under the undercut ie in the shoulder-shaped area 22, attacks. Of the

Shoulder-shaped portion 22 is thus convex in longitudinal section of the cap 17, in particular approximately

arcuate with respect to the center of the tilting movement of the dispenser 11 with the tilting valve. 2 As is apparent from Figs. 1 and 2, the dispenser 11 in the downstream connection to the inner channel 13 is a tubular connecting part 23 for a hose or a pipe, not shown in the drawing, whereby the medium to be sprayed or sprayed to its

Scope can be performed.

Furthermore, at the dispenser 11 is a T-shaped

Actuating arm 24 is provided over the manually the

Tilting movement of the dispenser 11 can be effected. In that shown in Figures 3 to 12

Embodiment is provided as an additional support of the dispenser 11 to the above-described and shown in Figures 1 and 2 measure a Baj onettverschluss between the dispenser 11 and the cap 17. Of the

Baj onettverschluss is designed such that the dispenser 11 in its mounting position with respect to the container 1 with attached cap 17 can be freely inserted through the central opening 19 of the cap 17 and placed on the valve nozzle 4. By subsequent rotation of the

Spender 11 by 90 ° from said mounting position to the operating position, in which it can be brought by pressing the operating arm 24 in its tilted position, the bayonet locking means of the dispenser 11 and the cap 17 cooperate, so that the dispenser against removal in the axial direction the tilting position and release of the mounting portion 12 is additionally secured by the valve nozzle 4.

Apart from the donor 11 and the cap 17th

formed bayonet closure means, the dispenser 11 and the cap 17 are basically as in the first described above and in Figures 1 and 2

Embodiment formed. In particular, the attachment area 12 of the dispenser 11 has a conical area 15 that widens toward its upstream end on, which extends over the conical annular flange 10 of the

Valve nozzle extends.

At the conical region 15 closes in the second embodiment considered here at the

upstream side additionally

cylinder jacket-shaped region 25, which extends over a downstream end region of the sealing part 3 of the

Foam can extends, as is apparent in particular from Figures 6, 7 and 9. In the transition region between the conical region 15 and the cylinder jacket-shaped region 25 of the

Fixing portion 12 of the dispenser 11 is provided a radially outwardly projecting annular flange 20, which can also be taken in particular Figures 6 and 7. On the downstream facing side of the annular flange 20 radially extending webs 26 are formed, the radially outer ends of which over the

extend annular flange 20 as projections 27 and which form the bayonet locking means of the dispenser 11, as will be explained in more detail below.

The two webs 26 with the projections 27 are arranged on the annular flange 20 diametrically with respect to the axis of the annular flange 20, and at a circumferential angle of 90 ° to that of the dispenser 11th

arranged actuating arm 24. As further apparent from Figure 6, the radially inwardly facing ends of the webs 26 with the conical portion 15 of

Attachment portion 12 of the dispenser 11 connected.

The projections 27 of the webs 26 act as

Bayonet closure means of the dispenser 11 as follows

Bayonet closure means of the cap 17 together.

As can be seen in particular from FIGS. 7 and 9, FIG the edge of the central opening 19 of the cap 17 at its downstream end portion a downstream

directed conical constriction 28. 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 to

Example, Figures 5 and 6 refer. The extension of the diameter of the opening 19 of the cap 17 is also given, for example, by comparing 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 mounting position of the dispenser 11 shown in Figures 3 to 7, this is introduced 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 to the recess 30 having edge region the opening 19 are directed. 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 mounting position previously described and shown in Figures 3 to 7 in the in Figures 8 to 10 shown actuating 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 at a release from the valve nozzle 4 and simultaneously removing from the

Opening 19 is prevented. The thus caused hold of the dispenser 11 can be seen in particular in FIG.

As is apparent from Figures 10 and 12, the above-described Baj onettverschluss obstructs the tilting movement of the dispenser 11 from the mounting position (see Figure 10) in the tilted position (see Figure 12) not. Even during the tilting movement and in the tilted position of the dispenser 11 of the Baj onettverschluss remains obtained by the projections 27 of the webs 26 of the mounting portion 12 of the dispenser 11 engage under the edge regions of the central opening 19 with a smaller inner diameter.

Further, as shown in Figs. 6 and 7, on the upstream side of the projections 27 of the ridges 26 of the attachment portion 12 of the dispenser 11 are respectively disposed two ridges 31 extending upstream from the projections 27 and their radially outer sides in the upstream direction are inclined radially inwardly. 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.

As also shown in FIGS. 6 and 7, the webs 31 are arranged on the radially outer side of plate-shaped parts 32 which are formed on the upstream-facing side of the annular flange 20 of the fastening region 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 ° arranged the projections 27 on the webs 26 upstream ribs 33, which also 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 serve, 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. As the plan views of Figures 3, 5, 8 and 11 show, the recess 30 is substantially

mirror-symmetrical to the plane parallel to the opening 19 and perpendicular to the plane in which the tilting movement of the dispenser 11 takes place. In addition, the

Recess 30 also substantially mirror-symmetrical to the plane in which the tilting movement of the dispenser 11 takes place, formed. 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.

For example, as shown in the sectional views of FIGS. 7 and 10, the region of the edge 19 of the cap 17 having the conical constriction 28 is provided at its upstream end with a circumferentially extending undercut 34. The undercut 34 serves to ensure that, as shown in FIG. 12, the radially outer edge region of the

annular flange 20 of the mounting portion 12 in the tilted position of the dispenser 11 under the conical

Constriction 28 having edge region of the opening 19 engages and thus with the inner region of the opening 19th

positively cooperates against removal of the dispenser 11 in the axial direction of the tilted position. 
