A medical drip-feed bag for dispensing fluids made of polyolefin polymer having flexible walls defining therein a collapsible space for storing said fluids, said bag comprising a sealable inlet for introducing fluids into the bag and an outlet for dispensing said fluids, said outlet comprising hermetically sealed connector means sandwiched between said walls, said connector means comprising a substantially lenticularly shaped body with integral nipple, said connector means further comprising a bore going through the body and nipple and forming a channel for fluid to flow out of the bag, said connector means consisting essentially of a polyolefin polymer and being heat sealed directly to said walls without an intermediate adhesive layer therebetween.
A method for manufacturing drip-feed bags from polyolefin comprising the steps of:
- preparing a bag from polyolefin polymer, said bag having an inlet and an outlet for fluids;
- and
- directly heat sealing a connector means consisting essentially of polyolefin having a substantially lenticularly shaped body with integral nipple and a central throughgoing bore through the body and nipple in said outlet, while the connector means is sandwiched in between the walls of the bag, without an intermediate adhesive layer between the walls and the connector.
