Abstract

L'invention concerne notamment un sachet (1) comprenant au moins deux parois (2, 3) souples mais déchirables disposées en regard; une marge (4) de solidarisation rigide des deux parois (2, 3) l'une contre l'autre, agencée pour délimiter d'une part la périphérie extérieure (6-9) du sachet (1) et d'autre part le contour externe (10-13) d'un volume central (5) destiné à contenir un produitpar exemple liquide, pâteux ou pulvérulent; et une ligne (18) de plus faible résistance qui s'étend sur la marge (4) de solidarisation et qui est destinée à permettre l'ouverture du sachet (1) par suite de l'arrachement des parois (2, 3); une première extrémité (19) de la ligne de plus faible résistance (18) étant située à un bord périphérique (7) de la marge (4) de solidarisation; caractériséen ce qu'à sa seconde extrémité (20), la ligne de plus faible résistance (18) présente une tangente (21) qui intercepte le contour externe (10, 13) du volume (5), pour qu'en déchirant les parois (2, 3) suivant la ligne de plus faible résistance (18), à partir de la première extrémité (19) et via la seconde (20), une ouverture de forme substantiellement prédéterminée soit réalisée dans le volume (5).The invention relates in particular to a sachet (1) comprising at least two flexible but tearable walls (2, 3) arranged facing each other; a margin (4) for rigidly joining the two walls (2, 3) against each other, arranged to delimit on the one hand the outer periphery (6-9) of the bag (1) and on the other hand the external contour (10-13) of a central volume (5) intended to contain a product, for example liquid, pasty or powdery; and a line (18) of lower resistance which extends over the margin (4) of attachment and which is intended to allow the opening of the bag (1) as a result of the tearing of the walls (2, 3); a first end (19) of the line of weakest resistance (18) being located at a peripheral edge (7) of the margin (4) of attachment; characterized in that at its second end (20), the line of weakest resistance (18) has a tangent (21) which intercepts the external contour (10, 13) of the volume (5), so that by tearing the walls (2, 3) along the line of weakest resistance (18), from the first end (19) and via the second (20), an opening of substantially predetermined shape is made in the volume (5).
