• the hollow shape for this mounting piece is preferred because it serves to serve as a vent and for the return of the component when filling the volume of the hollow tubular member 13.
• this passage is opening upwards by a orifice 51. If the shape and the volume of the cavity 52 of the hollow interior volume of the conical projection piece 47 are sufficient, it can receive the projecting portion 53 of complementary frustoconical shape for example of a removable closure piece 54 as shown in Figure 21 performing the function plug with a circular base 55 thus ensuring a good temporary seal.
• the conically projecting mounting piece 47 may have a central fractionable bottom portion, of the kind removable closure piece 56 having a gripping nipple 57. At least the circular central portion of its base could thus after splitting dissociate from the body of the mounting piece 47 and release the inner passage for filling the product and serve as a vent when used on the spray tool.
• a multi-component embodiment which may comprise several inner volumes each containing a component for example in the form of several concentric tubular elements whose volume of each of them is released successively in the peripheral volume remaining from the body 5.
• each component is contained in a separate individual container sealed from one another, without any of the components being able to mix before the preparation of the product to be sprayed.
• a communication can be obtained between these two at least individual containers so that the two at least components can be mixed in the same space without it being necessary to leave them and in which the mixture remains confined.
• the container body namely the largest, which can be closed by a tight cover to allow the mixing of the two components by vigorous stirring of the largest container .
• the two-component or multi-component product to be sprayed is prepared, it is sufficient to mount the largest container that contains the mixture on a paint or spray tool through an adapter piece for example a distribution cone cover.
