Abstract (en)
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). Those 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. <IMAGE>
