QQ emerging foam is contaminated, which is subject to moisture absorption then hardens and is extremely difficult to remove. The empty container comes with it the additional part sitting in the area of the container closure is thrown away as a disposable part. Since the container in this type of Absorption is exposed to large and varied forces, consists in there is a high risk of damage due to the strength requirements the container consists of a relatively expensive aluminum: monoblock container.

The design as a disposable part of this, along with the additional adapter element, represents an extremely large waste of material, - because one strives to as disposable parts to make certain elements as inexpensive and simple as possible. The recording and bracket of the container on the dispensing gun is inadequate in the known type of holding device. Lack other support there is a risk that the container kinks there in the area of the additional adapter part or is bent, in which case the entire container closure is detached from the container and that under pressure standing foam can emerge abruptly until the container is completely emptied and contaminate the environment. This harbors the risk of serious physical injuries, apart from the fact that in this way no intended use Further use is possible.

Another disadvantage is that the container with an additional adapter part on the one hand and the dispensing gun on the other hand must be adapted to each other and therefore conventional containers with tilting valve, but without the additional Valve adapters cannot be used in conjunction with the dispensing gun.

The invention is based on the object of providing a holding device of the type mentioned in the preamble of claim 1, which enables reliable alignment and support of the container without an additional adapter element being required on the container side, ^so that commercially available, simple containers with a tilt valve are used can, with the resulting advantages, whereby a reliable support of the container is ensured and the risk of the container accidentally in the area of the valve adapter is avoided

The invention achieves the following advantages. The container is simple and can be commercially available, since it does not need its own additional adapter element.

This opens up the possibility of using conventional tinplate cans as containers, "the are relatively light and also relatively inexpensive. Due to the low weight, handling is not caused by the container weight makes it even more difficult. Due to the low costs, there is no waste of material Throw away empty containers in limits. Each container is in two longitudinally spaced locations reliably held. One holder takes place in the area of the centering shoulder on which the container-side The cylinder part of the lock is fitted with a precise fit. Characterized in that the container at an axial distance therefrom on one ■ Another point is secured in such a way that axial forces act on the container coaxially to the centering shoulder, is the There is no risk of forces acting across the container during handling, which could result in the container being torn off of the dispensing gun in the valve area with all the disadvantages that arise therefrom. It is already sufficient to place the container on the protruding centering shoulder in the area of the container closure and e.g. at the opposite end of the container by means of an adaptable holding device to exert an axial force on the container, which causes the container with the cylinder part in the area of the container closure BS pressed onto the centering shoulder is and remains pressed, 'Whereby at the same time Kippvönt.ilst the tappet of the tilt valve is pressed in and the tilt valve is opened.

The valve adapter 13 has a projecting centering shoulder 15. This is a closure 16 of the container 11 associated with the eisi drawn inwards , 'Cylinder part 17 and one adjoining it

Has bottom 18 into which a valve 19 is inserted, that in the illustrated embodiment from a tilt valve consists. Such tilt valves are known per se.

De ^ outer diameter of the centering shoulder 15 corresponds

approximately the inner diameter of the drawn-in cylinder part 17, which thus fits exactly onto the centering shoulder 15. Of the The container 11 is thus with its cylinder part 17 of the closure 16 in a substantially coaxial alignment to the longitudinal center axis of the centering shoulder 15 can be attached to the latter with simultaneous centering. Of the Centering shoulder 15 contains a receiving opening in the interior 20 in the form of a bore into which a tappet 21 of the valve 19 protrudes.

Container 11 axially presses on the centering shoulder 15 simultaneous opening of Veritile 19. Details ■ this second end part 23 are described later *

The inner receiving opening 20 of the centering shoulder 15 is at least over part of its length, in the illustrated embodiment in the lower region 24, the outer diameter of the plunger 21 adapted and takes this on under sealing after sweet. At the lower end, dis Receiving opening 20 an inner; radially protruding Support surface 25, against which the plunger 21 can be pressed with its frontal end, thereby caused Insertion of the plunger 21 and opening of the valve 19. In Fig. 1, the valve 19 is already in this shown in the open position.

The valve adapter 13 contains a check valve 26, which is a valve ball, below the receiving opening 20 which is pressed upward into the closed position via a spring 26 in FIG. 1. Under the pressure of the When the valve 19 is open, the foam emerging from the container 11, the valve ball 27 counteracts the action the spring 28 is pressed down in FIG. 1, whereby the passage for the foam up to the dispensing gun 14 is released.

The valve adapter 13 has an externally threaded shoulder 29 with which it can be inserted into a matching internally threaded bore 30, the dispensing nozzle 14 is screwed in an exchangeable manner.

The first end part 22 assigned to the valve adapter 13 is made of a transverse bracket in the exemplary embodiment shown 31 formed either on the valve adapter 13 or, as in the embodiment shown, between the valve adapter 13 and the dispensing gun 14 is releasably attached. The cross bracket 31 is between the valve adapter 13 and the dispensing nozzle firmly clamped, like

particularly Pig * 1 shows.

The second end part 23 has a bottom 32 of the B. container 11 associated axial pressure member 33. The latter is arranged coaxially to the valve adapter 13 and is located on a carrier * which extends between the first end part 22 and the second end part 23.

In an embodiment not shown, there is the Axiaidruckgiied from a quick tensioning member that can be brought into the operative position by means of an eccentric or the like.

In the embodiment shown, the axial pressure member is 33 designed as a threaded spindle 34 with an end-side pressure piece 35, which by means of an external handle 36, in particular in the form of a handwheel, is adjustable. The pressure piece 35 consists e.g. of a plate, which is held captive at the free end of the threaded spindle 34, but rotatably relative to this. The lead screw 34 has a movement thread with a large pitch, so that with only a few screwing movements the handle 36 a large axial adjustment path can be achieved.

The guide part holding the threaded spindle 34 has a transverse bracket 37 which has a central internal thread which corresponds to the external thread of the threaded spindle 34. The transverse bracket 37 contains one in the center Bushing with at least a small axial extension and internal thread contained therein, whereby the latter is a s has a somewhat larger axial extent, which at the same time ensures axial guidance for the threaded spindle 34.

The carrier for the container 11 has in the embodiment shown at least two rods 38 and 39 which are approximately parallel to one another and which form from the first end part 22

of the cross bracket 31 to the second Efrdteil 23 in the form of Cross bracket 37 run and engage firmly on both; The transverse distance between the two rods 3Ö> 39 is ritir little larger than the outer diameter of the container 11. On the length between the two end parts 22, 23 on one side of both rods 38, 39 is an upper one Cross support 40 and a lower cross support 41 are provided, which are each bent approximately semicircular and by means of which the container 11 additional borrowed transversely to its longitudinal axis and about '"να π η s π a rt i g is supported. Every cross support 40, 41 consists of a correspondingly curved flat strip. The carrier designed in this way, consisting of the two longitudinal guide parts in the form of rods 38, 39, the the two end transverse brackets 31, 37 and the transverse supports 40, 41, forms an integral support part with these parts. This support part can ormteil from a one-piece plastic, metallic casting or from a welded one Support part exist.

In another exemplary embodiment, not shown instead of the two rods 38, 39, the carrier has rods, pins, strips or the like.

In a further exemplary embodiment not shown the carrier has at least one longitudinal guide part which leads from the first end part 22 to the second end part 23 and extends approximately parallel to the axis of the container 11. This longitudinal guide part can be approximately trough-shaped Have farm receptacle for the container, e.g. in the form of an approximately semi-cylindrical receptacle shell that Can be formed from plastic, sheet metal or the like.

The container 11 is placed with its cylinder part on the centering shoulder 15 in the direction of its longitudinal center axis. Thereafter, the axial pressure member 33 is brought into the operative position by means of de;: - Handle 36. The handle 36 is rotated until the pressure piece 35 not only rests on the bottom 32 of the container, but also exerts an additional axial force on the container 11, by means of which the container 11 is advanced in the axial direction towards the valve adapter 13. The cylinder part 17 of the container pushes itself onto the centering shoulder 15, the plunger 21 of the valve 19 pushing open the support surface 25 and a further axial pushing of the container 1-1 pushing in the plunger 21 and thus opening the valve 19 Consequence. The foam contained in the container 11, which is under propellant gas, is then introduced through the open valve 19 under pressure, overcoming the force of the spring 28 and opening the non-return valve 26, through the valve adapter 13 and into the dispensing gun 14, from the outlet pipe 42 of which the foam is introduced can escape in a dosed amount. If the container 11 is to be removed as a not yet fully emptied container or in a completely emptied state, the axial pressure member 33 is rotated axially away from the base 32 by rotating the handle 36, at least around
