Patent

CA 2239006

A container (10) for fluids or liquids such as beverages and the like is formed of flexible material such as plastic and includes a body (12) having an internal reservoir (14) and a tubular spout (30) extending upwardly from the body. The spout has an internal passage (32) in fluid communication with the reservoir. A constriction (34) in the container creates a low pressure zone in the passage downstream of the constriction as liquid flows from the reservoir into the spout. Means are also provided to inflate the spout as fluid flows along the internal passage. A method of forming fluid-filled containers from a tube (58) of flexible material and a method of forming a self-supporting fluid- filled container are also disclosed.

Un récipient (10) destiné à des fluides ou des liquides tels que des boissons et analogues est constitué d'une matière souple telle que du plastique et présente un corps (12) comportant un réservoir intérieur (14) ainsi qu'un bec tubulaire (30) surmontant verticalement le corps. Le bec présente un passage intérieur (32) en communication fluide avec le réservoir. Un étranglement (34) ménagé dans le récipient crée une zone de basse pression dans le passage, en aval de l'étranglement, à mesure que du liquide s'écoule du réservoir dans le bec. On a également prévu des moyens destinés à gonfler le bec à mesure qu'un fluide s'écoule le long du passage intérieur. L'invention concerne également un procédé de formation de récipients remplis de fluide par un tube (58) en matière flexible, ainsi qu'un procédé de formation d'un récipient auto-porteur rempli de fluide.
