摘要： Pressurisable container for storing and ejecting liquid, the container comprising a) a front wall having or surrounding a cavity corresponding to the form of an open vessel, b) an opening in the front wall adapted for ejection of the liquid from the container, said opening defining a container axis, c) optionally a sealing over the opening adapted for temporary use, and d) a rear wall closing and sealing the open part of the front wall vessel to confine a space for the liquid in the container, the rear wall running at least partially perpendicular to the container axis and being displaceable or deformable for movement towards the opening to pressurize the container liquid. The front wall is substantially rigid in relation to the rear wall, the rear wall before pressurizing the container is substantially flat or substantially single-curved and the rear wall is deformable under stretching to substantially fill out the container cavity. The invention also relates to methods for container manufacture and devices and methods for ejecting liquid from the containers.
