Plastics bag, for packaging liquid, comprising a leaktight chamber and a pocket, adjacent the chamber, housing a pipe for withdrawing liquid from the chamber

摘要

A bag 30 for packaging liquid formed by a plastic film, comprises a sealed chamber for liquid, a pocket 33 in which is located a conduit (straw 21) for withdrawing the liquid, and means 4 to give access to the inside of the pocket. An opening is formed through part of the wall of pocket 33, adjacent the chamber, to allow the conduit to penetrate the chamber in a leaktight manner. The opening is located at the end of a tubular element (seal 7a), of decreasing cross-section, at the point where the section is smallest. The element is formed from a film of plastic forming one wall of the pocket adjacent to the chamber and is intended to accommodate the conduit and form a seal therearound. The means for giving access to the inside of the pocket may comprise a tab 4a cut from one of the layers of film forming the chamber .
