Abstract
Abstract A bag 10 for containing liquids is formed by welding together two plastic sheets around their peripheries and includes a neck portion 11 for connection to an outlet. An outlet tube 13 is partially inserted into the neck portion leaving a part of the tube with an upstanding seal member 17 outside the neck portion. A sleeve 18 is passed over the neck portion and the sleeve is shrunk into place, urging the neck portion 11 into tight engagement with the outlet tube 13 and effecting a seal between the sleeve 18 and the seal member 17 on the outlet tube 13.
