The present invention relates to a stand up bag of a heat-sealable or weldable plastic film for receiving liquid and/or paste-like material, the bag comprising two side walls connected to each other along their longitudinal edges, a foldable bottom member which is positioned between the side walls and serves as a self- standing bottom being inserted at the lower end of the stand up bag between the lower transverse edges, and a foldable cover member being positioned at the upper end of the stand up bag between the side walls, and comprising a removal opening between the upper transverse edge of a first side wall and the corresponding cover member edge, with a closure element being inserted into the removal opening. To be able to empty the stand up bag in a better and simpler way, the closure element is bendable and is retained by a means for stabilizing and retaining the forwardly bent closure element.

L'invention concerne un sachet à fond plat (1) réalisé dans une pellicule plastique thermosoudable ou soudable, destiné à contenir des produits liquides et/ou pâteux. Ce sachet comporte deux parois latérales (2,3) interconnectées au niveau de leurs arêtes longitudinales. A l'extrémité inférieure du sachet, entre les arêtes transversales inférieures, il est prévu d'insérer une partie de base (10) pliable servant de fond, située entre les parois latérales. A l'extrémité supérieure, entre les parois latérales, le sachet comporte une partie de couverture (11) pliante. Le sachet présente par ailleurs une ouverture de soutirage située entre l'arête transversale supérieure d'une première paroi latérale et l'arête correspondante de la partie de couverture. Un élément de fermeture est inséré dans l'ouverture de soutirage (12). Afin de pouvoir améliorer et de faciliter le vidage du sachet à fond plat, l'élément de fermeture (20) est rabattable et est maintenu par un dispositif destiné à stabiliser et à maintenir l'élément de fermeture rabattu vers l'avant.
