Bag comprising a closure device fixed to extension webs

摘要

The invention relates to a bag (1) comprising: —two walls (10, 20), —two support webs (12, 22), each comprising at least one complementary section (3), an upper edge (12a, 22a), —two extension webs (14, 24), each comprising an upper part (14a, 24a) fixed to a respective wall (10, 20) of the bag (1) close to the mouth (5), and a lower part (14b, 24b) that is movable with respect to said wall (10, 20), the support webs (12, 22) being fixed to a respective wall (10, 20) by way of a respective extension web (14, 24) away from their upper edge (12a, 22a), such that the traction on the walls (10, 20) of the bag (1) when the complementary sections (3) are in contact causes the support webs (12, 22) to rotate about said complementary sections (3).
