ABSTRACT:
A bag-like liquid container especially intended for medical use is formed from flexible material and includes at least one closable spout for filling or emptying the container, having its center line substantially in the plane of the flat container, the spout being provided with a flange formed integral therewith, said flange being weldably unitable to the container material for providing a completely impervious attachment of the spout to the container as well as a separation of the sides of the container so that liquid flowing into and out of the container is always guaranteed a free passage.
