Compressible cylindrical container with integrated screw, compression nut and bellow system

Abstract

The invention is a container with a sealing lid and a compression nut and is composed of compressible cylindrical walls. The container volume can be adjusted to equal the volume of content minimizing content contact with air. The container can be further pressurized for preservation of contents that need pressurization. The container walls are created in the form of helical collapsible screw thread bellows. The integration of a compression nut, a screw and a collapsible bellow arrangement enables the container to be compressed precisely, effortlessly, easily while retaining structural rigidity, stability and providing a non-slip gripping surface. By adjusting the pitch of the screw threads a variety of mechanical advantage ratios can be achieved thus the effort for compressing the container can be optimized. The compression nut is detachable and transferable from one container to another enabling it's cost to be shared between multiple containers.
