Abstract: A pressurizable package for a substance to be dispensed is formed by inserting a flexible liner into a pressurizable container and holding the closure of the container away from the mouth so that the space between the liner and the container can be pressurized with a gas. The closure is then sealed to the container to seal the space and maintain the pressure of gas around the liner which is evacuated to further collapse the liner, by applying a suction to a valve on the closure communicating with the interior of the liner. The liner is then filled through the valve with the substance to further pressurize the gas in the surrounding space.

Abstract: The invention pertains to a liner made of elastic, deformable, flexible material. By the special design of the contours in the area of its opening, shoulder, sides, and its bottom, the liner is intended to be so firmly attached to a top, that the assembled components can be handled, stored, and transported as a single unit. The liner, by its quality and form is, by vacuum, completely contracted in the moment of its pneumatic attachment and will be fixed at the top and oriented to its intended resulting shape and direction. Such a liner is used in connection with the manufacturing of a valve liner unit which is intended to be used in a pressurized container.
