<p>Device for reducing the space taken by a container for liquid materials by folding it and maintaining it in a folded position by self-locking. The invention relates to a device for folding a container configured like bellows (1) and for maintaining the container in a folded position by self-locking by nesting the container bottom (2) presenting an extra width (6) into the groove (7) of the container neck (3) or vice-versa. The concave conical shape of the botton (2) provides for the nesting of successive containers. The device is particularly adapted to reduce the space taken by empty containers for all applications before use and essentially as waste; it also reduces the air volume of the container when the latter is only partially filled.</p> |
