Pig. 6 is section VI-VI in Pig. 5 ·

The aerosol can 1 is inserted into a substantially rectangular housing and covered on all sides by this. According to the pig. Λ to 4, the housing consists of a lower part 2 and an upper part 3, which can be displaced transversely with respect to one another, longitudinal guides. The housing is also polygonal in outline, e.g. B. look for 6-, 8-, 12-eekig, 'provided that only the upper part can be moved transversely with respect to the lower part.

The aerosol can 1 has a known spray valve which can be actuated by pressing the spray head 4, namely by axial pressure as well as by any radial, i.e. horizontal pressure * When actuated occurs essentially axial, so vertical spray from. The arrangement can also be such that the spray jet is at an angle exit. The spray head can also be out of round in order to determine the exit direction.

The spray head 4 is received in a bore 5 in the Top of the upper housing part 3 «The upper housing part 3 is relative to the lower part 2 can be displaced transversely, namely here are inwardly directed guide strips 6 on the two Side walls of the upper part 3 are provided, which engage under corresponding guide strips 7 on the lower part 2. As in particular 4 shows are above the guide strips 7 AnI on wall parts that are inclined or inclined towards one another 8

provided, so that the upper part 3 and lower part 2 are axLel mensteokbar together, so the guide means 6/7 simultaneously form a Sohnapp-Ra st connection. Hereby a simple assembly is achieved

The upper part 3, which extends over the edge at the edge, is suspended from the wall with its rear side tm a hook 9. Instead of the eyelet 10, another device for fastening to the wall, in particular an adhesive strip, could also be provided. The lower part 2 lies over a web 1. In its lower area on the wall, however, it has. In the rest of the way opposite the wall and also opposite the back of the upper part J Spie /. This game E, by which the lower part 2 opposite the upper part 3 along l guides 6, 7 on the wall is too flexible, corresponds to the horizontal displacement path required to actuate the spray head 4. The can 1 has wedges play in relation to the lower housing part 2 in the direction of displacement, i.e. in the direction of the wall.

When pressure is applied to the front side 12 of the housing in the direction of the wall (arrow 13 in FIG. 3), the lower part of the housing and thus the aerosol can 1 are shifted accordingly, more precisely, pivoted around the web 11. Here, since the spray head is retained in the 5ehäuseoberteil 3 4, the spray head relative to the socket Λ is displaced horizontally, whereby the
