A container (51) for storage and dispensing of fluids, comprising collapsible front (54) and rear walls (56) defining a chamber, having a gland (50) defining a fluid passage for allowing the passage of fluids into the chamber carried on the front wall (54) of the container (51). The gland (50) includes a sealing land (59) within the container for sealingly engaging a heat sealable membrane (61) along a continuous seal upon the application of heat through the rear wall (56) of the container. The sealing land (59) in a pre- sealed condition, includes at least one thermo-deformable projection (64) having a raised profile providing an initial melt zone of reduced area relative to the area of the sealing land.

L'invention porte sur un contenant (51) destiné au stockage et à la distribution de liquides, qui comprend des parois avant (54) et arrière (56) repliables définissant une chambre et, soutenu sur la paroi avant (54) du contenant (51), un presse-garniture (50) définissant un passage fluidique qui permet le passage de liquides dans la chambre. Le presse-garniture (50) comprend une plage de scellement (59) à l'intérieur du contenant, qui est destinée à entrer en contact hermétique avec une membrane thermoscellable (61) le long d'un joint étanche continu lorsque de la chaleur est appliquée à travers la paroi arrière (56) du contenant. La plage de scellement (59), à l'état préalable au scellement, comprend au moins une projection thermodéformable (64) à profil surélevé qui constitue une zone de fusion initiale de superficie réduite par rapport à la superficie de la plage de scellement.
