Including: (a) at least one floppy disk material plate combined into a semi closed container, the opening of which is determined by the edge, and defining an opening plane, including the above materials: (I) a plurality of first areas; （2） The diversity of the second area, including multiple elements in ribs, which are visually different, even if they are made of the same material, and when the application of leaf material on at least one axis extends,(i) Substantial deformation at the molecular level, (II) undergoing basic geometric deformation; and (b) sealing and closing means of converting a semi closed container into a closed container; and The trading capacity expands its scope to cope with the driving force of content within the exchange, increasing its capacity to accommodate content, part of which extends to the first direction, The rest (I) is extended to a direction perpendicular to the previous one, so that they cross each other to form (I) a restriction completely surrounding (II)
