Patent

CA 2162592

A pliable, fluid dispensing pouch is provided which includes a flexible shot-chamber having a venturi shaped outlet passageway leading to a discharge opening at one end of the pouch. The discharge opening is initially sealed closed by the presence of a sealing tab. The discharge opening is unsealed by tearing off the tab. The venturi shaped outlet passageway has a throat section in which a liquid meniscus forms during use which acts to prevent leakage from the pouch when not in use.

Sac de distribution de fluide pliable comprenant une chambre de dosage souple (34) possédant un passage de sortie (40) en forme de venturi s'étendant jusqu'à un orifice de distribution débouchant dans l'une des extrémités du sac. Au départ, l'orifice de distribution est obturé par la présence d'une languette d'étanchéité (50). On ouvre l'orifice de distribution en arrachant la languette. Le passage de sortie en forme de venturi comporte un col (44) dans lequel se forme pendant l'utilisation, un ménisque de liquide servant à empêcher toute fuite lorsque le sac n'est pas utilisé.
