A flexible film pouch includes an aperture to access its contents, and a closure means such as a re-sealable spout is applied over the aperture to permit sealed storage of the contents after opening. The closure means is attached to the flexible film pouch by means of a patch that is bonded to the inside of the pouch adjacent to the aperture. The patch is selected to have a mating surface that bonds with the inner surface of the pouch, where such bonding is preferably conducted by ultrasonic welding or adhesive bonding. The patch itself may have a hole that permits access to the contents of the pouch, or the closure means may include a cutting surface that tears a portion of the patch to permit access.

L'invention concerne une poche de film flexible, comprenant une ouverture permettant d'accéder à son contenu, et à laquelle des moyens de fermeture, tel qu'un bec verseur refermable, sont appliqués sur l'ouverture de manière à permettre une conservation hermétique du contenu après l'ouverture. Les moyens de fermeture sont fixés à la poche de film flexible au moyen d'une pastille qui est collée à l'intérieur de la poche à proximité de l'ouverture. La pastille est sélectionnée de manière à présenter une surface d'accouplement qui est collée sur la surface intérieure de la poche, ledit collage étant de préférence exécuté sous la forme d'un soudage aux ultrasons ou d'une liaison adhésive. La pastille elle-même peut comporter un trou qui permet d'accéder au contenu de la poche, ou les moyens de fermeture peuvent comprendre une surface de coupe qui déchire une partie de la pastille pour obtenir un accès.
