Patent

CA 2264922

A bag construction (1) for use to distribute flowable material is provided. The bag construction generally includes first (4) and second (5) panels or panel sections oriented juxtaposed to one another. In one end of the bag construction, a base gusset (8) is provided between the panels. The base gusset includes apertures (9) therein, for distribution of flowable materials. In preferred embodiments, a rib-and-trough closure arrangement (31) is provided so that the pouch construction can be selectively closed to inhibit distribution of material, when desired. Methods of preparing such arrangements and methods of use are provided.

Le sac (1) faisant l'objet de l'invention, conçu pour distribuer une matière fluide, est généralement doté d'un premier panneau (4) et d'un deuxième panneau (5), ou de sections de panneaux orientés de façon à être juxtaposés l'un par rapport à l'autre. Un soufflet (8) est prévu à l'extrémité de fond du sac, entre les deux panneaux. Ce soufflet contient des ouvertures (9) qui servent à la distribution des matières fluides. Des formes d'exécution préférées prévoient des fermetures de type fermeture éclair (31), qui permettent, si on le souhaite, de fermer le sac afin d'empêcher la distribution de la matière. L'invention porte également sur des procédés de fabrication de sacs de ce type, ainsi que sur leurs procédés d'utilisation.
