The gist of the variable volume package with a jacket unfoldable in plane (1) is that it consists of the deformable walls (3 and/or 3') interconnected into a polygon of at least three edges, with the first wall (5) connected to the edges, and the second wall (6) connected opposite the first wall (5), at the opposite side of the deformable walls (3 and/or 3'), and the two walls form the enclosed jacket (2). The variable volume package with a jacket unfoldable in plane (1) makes it possible to squeeze out very efficiently the contents by application of insignificant force. |
