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. With this valve liner unit, it is possible to easily manufacture a pressurized container by a method according to which the container is first pre-pressurized with compressed air or other compressed gases, while the filling goods make no contact with the inner walls of the container and whereby it is not necessary to create an additional opening to the container instead of the one opening for inserting the valve liner unit. The filling goods can be introduced into the pre-pressurized container according to this method without contact with environmental air.
