Abstract
L'invention porte sur un système prérempli à deux constituants qui est pourvu de premier et second réceptacles ou cylindres. Le premier cylindre comprend une première chambre présentant une extrémité de distribution ou d'administration. Cette extrémité forme un passage de distribution ou d'administration communiquant dans l'extrémité de distribution de façon à faciliter l'administration du fluide provenant de la première chambre. Un joint amovible ou bouchon est placé dans la première chambre, et un premier constituant est versé dans la première chambre entre l'extrémité de distribution et le bouchon. Un second réceptacle ou cylindre est dimensionné de façon à se placer dans le premier cylindre et comporte une extrémité d'évacuation formant un passage d'évacuation communiquant par l'extrémité d'évacuation de façon à faciliter l'évacuation du fluide du second cylindre. Un piston est disposé coulissant dans le second cylindre. Un second constituant liquide est versé dans le second cylindre entre l'extrémité d'évacuation et le piston. Le bouchon du premier cylindre et l'extrémité d'évacuation du second cylindre peuvent s'engager directement ou indirectement de façon à former un accouplement facilitant l'écoulement du second constituant liquide, du second cylindre à la première chambre du premier cylindre, au moment où le second cylindre se déplace vers l'extérieur par rapport à la première chambre.
