A method for the fabrication of a container, comprising the steps of: - Providing a preform, said preform being substantially tubular and being provided with an open end communicating with a cavity; - Positioning said preform within a mold such that said open end of said preform protrudes from said mold, the shape of said mold substantially defining a container; - Providing an injection means (112, 118, 119, 123, 125), said injection means (112, 118, 119, 123, 125) configured to inject a quantity of liquid into said cavity of said preform and comprising a feed pipe connected to a liquid supply and controlled by a feed valve, a nozzle provided with a nozzle mouth and a nozzle valve, the nozzle mouth being configured to fit over the open end, and the nozzle valve being configured to open and close fluid communication between the injection pipe and the nozzle mouth, the injection means further comprising an injection pipe disposed to establish fluid communication between the nozzle and an injection cylinder, the injection cylinder containing an injection piston translatably disposed within said injection cylinder, said injection cylinder being provided with a return pipe in fluid communication with the liquid supply and controlled by a return valve, - disposing said nozzle mouth in sealed fluid communication with said open end of said preform using means (115, 116) for retracting/advancing the nozzle, - Injecting said quantity of liquid into said cavity of said preform, thereby increasing the pressure within said cavity and inducing said preform to deform into the shape of said mold and form a container; - Reducing the pressure within said container to atmospheric pressure while maintaining sealed fluid communication between said injection means (112, 118, 119, 123, 125) and said open end by withdrawing the injection piston, and - Upon completion of said reducing, closing the nozzle valve and the feed valve, and opening the return valve, fully advancing the injection piston to expel any uninjected liquid through the return pipe back to the liquid supply, then disengaging the nozzle from the container, using means (115, 116) for advancing/retracting the nozzle. - Providing a preform, said preform being substantially tubular and being provided with an open end communicating with a cavity; - Positioning said preform within a mold such that said open end of said preform protrudes from said mold, the shape of said mold substantially defining a container; - Providing an injection means (112, 118, 119, 123, 125), said injection means (112, 118, 119, 123, 125) configured to inject a quantity of liquid into said cavity of said preform and comprising a feed pipe connected to a liquid supply and controlled by a feed valve, a nozzle provided with a nozzle mouth and a nozzle valve, the nozzle mouth being configured to fit over the open end, and the nozzle valve being configured to open and close fluid communication between the injection pipe and the nozzle mouth, the injection means further comprising an injection pipe disposed to establish fluid communication between the nozzle and an injection cylinder, the injection cylinder containing an injection piston translatably disposed within said injection cylinder, said injection cylinder being provided with a return pipe in fluid communication with the liquid supply and controlled by a return valve, - disposing said nozzle mouth in sealed fluid communication with said open end of said preform using means (115, 116) for retracting/advancing the nozzle, - Injecting said quantity of liquid into said cavity of said preform, thereby increasing the pressure within said cavity and inducing said preform to deform into the shape of said mold and form a container; - Reducing the pressure within said container to atmospheric pressure while maintaining sealed fluid communication between said injection means (112, 118, 119, 123, 125) and said open end by withdrawing the injection piston, and - Upon completion of said reducing, closing the nozzle valve and the feed valve, and opening the return valve, fully advancing the injection piston to expel any uninjected liquid through the return pipe back to the liquid supply, then disengaging the nozzle from the container, using means (115, 116) for advancing/retracting the nozzle.
