A container 1 obturated by a closure in the form of a disc connected by the means ensuring its sliding on one side inside the collar of the container 1 and on the other side inside a skirt formed on the obturating top of the cap 3 screwed on the collar; the cap 3 unscrewed and stopping the closure in a position in which it opens the passage for fluid between the container and the cap and between the cap and exterior; the container 1 comprising deformable walls rigidly assembled by the caps 3 and 16 formed in one piece with any known container 17 making it possible, without separating the two containers, to open the passage between the two containers and to expel under pressure the fluid contained in the container 1 into the container 17. <IMAGE>
