<p>The bag (1) has two parallel sheets (12, 13) for forming main walls, and a slider (5) with flanks (51, 52), whose internal faces respectively carry bosses (53, 54). Male and female sections (2, 3) are respectively fixed on the sheets, and one of the bosses is directed towards the respective flank. The slider activates the sections for closing and opening the sections towards the bosses. Stop units (6) i.e. flanges, are provided on external surfaces of the sheets and immobilize the sheets relative to the slider along a direction perpendicular to a displacement axis (X-X') of the slider.</p> |
