This invention concerns containers intended to contain aerosol solutions under pressure and has for one object the provision of a container which is capable of being fixed very quickly on appartus into which it is desired to introduce its contents.

According to one aspect of this invention, there is provided a container intended to contain an aerosol solution, such container having a cylindrical portion provided with attaching means of the bayonet joint type, whereby the said container can be fixed to a support by engaging this cylindrical portion in an appropriate opening, and then rotating the said container.

The said cylindrical portion may be carried by a block adapted to receive two or more aerosol bottles and having an outlet duct to which the interiors of both bottles are connected when attached to said block.

According to a further aspect of this invention, there is provided the combination of a container according to this invention with a support intended to receive the said container, such support having a bayonet joint socket which is adapted to co-operate with said bayonet joint attaching means and comprising a nose provided with a slot, the said nose being capable of causing the opening of a valve with which the container is provided.

The bayonet joint attachment can be used simply to hold the container in a given position on the support, but it is also possible for the arrangement to be such that, during fixing of the container on the support a nose is made to be introduced against the movable part of a valve which closes the container, so that one and the same movement both locks the container on the support and connects its interior to a duct in the support.

According to a further feature of the invention, the support may be in the form of a gun having a trigger carrying a socket adapted to receive the bayonet joint attachment means of the container, the arrangement being such that, when the container is attached to the support, the valve is not opened by the said nose, but depression of said trigger moves the socket, and with it the container, towards said nose so that the valve is then opened.

In order that this invention may more readily be understood, the following description will now be given by way of example, with reference to the accompanying drawing, wherein:

FIGURE 1 is a perspective view of an aerosol container according to the invention;

FIGURE 2 is a perspective view of a gun for discharging aerosol solution and adapted to receive the container shown in FIGURE 1;

FIGURES 3 and 4 are partial sectional views of the container of FIGURE 1 mounted on the gun shown in FIGURE 2 with the aerosol-discharging gun in inoperative and operative conditions respectively;

FIGURES 5 and 6 are sectional views of the bottle and of its support on the line V—V in FIGURE 1 in the unlocking and locking positions respectively;

FIGURES 7 and 8 show diagrammatically in sectional view how it is possible both to fix the container with bayonet joint means according to the invention to its support and to connect the interior of the said container to a duct situated on the said support; and

FIGURE 9 is a perspective view showing a variant of the device of FIGURES 1 and 2, by means of which variant it is possible to discharge a mixture of aerosol solutions;

FIGURE 9α is a longitudinal section through the embodiment illustrated in FIGURE 9, taken through the axis of both containers.

FIGURE 1 shows a container 1 according to this invention, the container being in an inverted position. At its lower end the container is provided with a valve 2, not shown in detail in this figure, which may be of any desired type which makes it possible to take from the container some of the aerosol liquid contained within the said container, whilst closing the said container in a sealingtight manner when there is no action on the valve.

Between the valve 2 and the body of the container 1, there is situated a substantially cylindrical portion 3 which is provided peripherally near its lower end with two abutments 4 and 5 arranged symmetrically one on each side of the container.

FIGURE 5, which represents a section taken through the container 1, shows again the cylindrical portion 3 and the abutments 4 and 5 which extend over two arcs of a circle in symmetrical fashion.

The container 1 may be made, for example, of moulded glass, but it may also be constructed from some other material such as, for example, a plastics material.

The gun shown in FIGURE 2 is essentially consituted by a body 6 the lower portion 7 of which forms a butt, a trigger 8 being pivoted at 9 on the body of the gun. At its upper part, the trigger 8 carries a movable support 10 which receives the container 1.

As FIGURE 2 shows clearly, the support 10 has an opening 11 provided with grooves 12 and 13 of a shape to pass the abutments 4 and 5 when the cylindrical portion 3 of the container is engaged in the opening 11.

All that then remains to be done in order to lock the container on the support 10 is to rotate the container 1 through about a quarter of a revolution, so that the abutments 4 and 5 on the container are caught beneath the abutments between the grooves 12 and 13 on the support 10.

FIGURES 5 and 6 show the respective positions of the support and the container before and after locking.

It will be noted that the described bayonet joint connection enables the container 1 to be fixed on the support 10 in a particularly simple and rapid way and that it is easy to replace the container 1 on the gun.

The body of the gun carries below the support 10 a part 14 which is provided with an atomising orifice 15 connected to a valve-actuating nose 16 by a duct 17, the valve-actuating nose 16 being provided with a slot and being situated in the center of a rubber stud 18.

As FIGURE 3 shows, when the container 1 is placed on the support 10, the end of the nose 16 engages in the orifice of the valve 2 but does not act on the valve, so that the container 1 remains closed.

Finally, it will be apparent that the containers provided with attachment means according to the invention may be used for connection to apparatus other than the gun which has been described herein.
