A contraction-controlled bellows container (1) is disclosed, which can retain half or fully contracted configurations of the bellows ridges (2) whose upper walls (21) and/or lower walls (22) have at least one circumferential indentation (3) adjacent the corresponding outer hinges (23) and/or inner hinges (24). The indentations utilize the pressure applied onto the container effectively and get depressed further into the corresponding bellows ridges prior to the corresponding portions of the other walls, reducing the total pressure requirement. The indentations bring together the walls in which the indentations are provided into the bellows ridges (2). These walls are gradually turned in shape to lose their shape restoration thanks to their generally protruding configuration. Adjustment of the sizes of the indentations makes it possible to selectively contract the bellows ridges.

[ What is claimed is:] [1.] A contractible bellows container comprising:a bellows ridge having an upper wall and a lower wall, said bellows ridge being positionable in an open state in which said upper wall and lower wall are spaced apart and in a contracted state in which said upper wall and lower wall are proximate;said upper wall and said lower wall being coupled by an outer hinge;said upper wall being coupled to a first adjacent bellows ridge by a first inner hinge;said lower wall being coupled to a second adjacent bellows ridge by a second inner hinge;wherein in said open state, one of said upper wall and said lower wall is generally s-shaped and includes a concave deformation and the other of said upper wall and said lower wall is generally convex.
