CA 2196108

A plastic film liquid pouch is formed from impermeable film sheet material and has opposed side walls with sealed circumferencial edges to form an enclosed chamber. A liquid product is provided in the chamber and a space is also provided to permit expansion of the liquid. An internal straw restraining passage is formed by seals between the opposed side walls. The straw restraining passage communicates with the liquid chamber and a straw is held loosely captive inside the passage and axially displaceable therein . The straw restraining passage defines a reduced cross-sectional area of the chamber whereby the opposed side walls of the bag at the restraining passage may be collapsed towards one another by the fingers of a user person thereby displacing a restricted quantity of liquid to expose the straw to grasp the straw and push an end of the straw through the film sheet material whereby to extract the liquid from the pouch either by sipping it through the straw or by compressing the pouch to force the liquid through the straw.

Une poche plastique de liquide est constituée d'une pellicule imperméable et comporte des parois latérales opposées dont les bords circulaires sont scellés pour former une chambre fermée. La chambre contient un produit liquide et comprend un espace permettant l'expansion de ce dernier. Un passage interne de contention de la paille est formé par des joints d'étanchéité placés entre les parois latérales opposées, communique avec la chambre et emprisonne librement une paille qui peut s'y déplacer axialement. Il définit une zone de coupe transversale réduite de la chambre par laquelle un utilisateur peut rapprocher, en appuyant au moyen de ses doigts, les parois latérales opposées de la poche, qui se trouvent près du passage. Ainsi, l'utilisateur déplace une quantité restreinte de liquide pour exposer la paille, la prendre et pousser une des ses extrémités à travers la pellicule afin d'extraire le liquide de la poche soit en le sirotant au moyen de la paille, soit en comprimant la poche pour forcer le liquide à sortir par la paille.
