ABSTRACT:
A combination of a liquid-containing bag and a tube 28 is disclosed. The bag may be a urine drainage bag and is made up of a pair of superposed sheets 20, 22, joined by a weld 24 whose configuration is chosen to define in a single welding operation the outline of the bag and the tube integral therewith. A single weld seam 24 defines the bag volume. The tube and portion of the weld seam 24 run adjacent to one another and are separated by a row of perforations 30 or by a line of weakening. In such an arrangement, means are provided for precluding face-to-face contact of selected parts of the inner surfaces of said sheets. This may be done by effecting heat shrinkage of selected parts of one or both sheets. One or preferably both sheets is biaxially oriented.
