Abstract
Sachet comprising: a first and a second wall (10, 20), a closure assembly (3) comprising a first and a second support web (30, 32) that are connected to the first and the second wall (10, 20), respectively, and each have a closure element (34), the first support web (30) being connected discontinuously along its length to the first wall (10) of the sachet (1) so as to form at least one passage (40) between this first support web (30) and the first wall (10) of the sachet (1) from the outside of the sachet (1), said passage (40) allowing local deformation of the first support web (30) for modifying the relative local orientation of the closure elements (34) while the walls (10, 20) are being moved apart and making it easier to separate the closure elements (34).
