First Claim
1. A device enabling at least two substances to be stored separately, to be mixed together, and the resulting mixture to be dispensed, the device being of the type comprising a receptacle and at least one removable shutter suitable for separating inside the receptacle two chambers containing said substances respectively prior to first use of the device, the device further including a pushbutton for moving on first use to cause said shutter to be moved away or torn and the two chambers to be put into communication with each other, the device including a gasket comprising a portion fixed to the receptacle and a deformable portion made of an elastically-deformable material, suitable for deforming when the pushbutton is depressed so as to accompany the movement thereof, while continuing to constitute a sealing barrier between the inside of the receptacle and the pushbutton.

23. A method of manufacturing a device for separately storing at least two substances, for mixing them together, and for dispensing the resulting mixture, the method comprising the steps consisting in:
-
making a hollow body provided with removable closure means at one end and open at another end; making an end portion by integral molding, said end portion including a base and a cover connected together by a film hinge, said cover including a pushbutton connected to the remainder of the cover via at least one bridge of breakable material, said end portion including a chimney; fixing or forming a removable shutter at one end of said chimney; filling said chimney with a first substance; applying a gasket onto said chimney and shaped to close said chimney; applying the cover onto the base by pivoting about the axis of rotation of said film hinge; filling said hollow body with a second substance via said open end; and fitting said end portion on said open end of said hollow body.
