Ecological packaging with variable volume

摘要

The interior (3) of the packaging is defined by a hermetically sealable casing (2) with at least one deformation zone consisting of at least one deformation surface. Two deformation surfaces are joined by a shared flexible edge. The outer casing is attached to the deformation surface by means of a bending edge (8). The volume (1) of the packaging can be altered. The outer casing can contain an opening with closure piece, holes or stabiliser.
