ABSTRACT:
A synthetic plastic bag for containing liquids, e.g., urine, has a plastic outlet tube. It is manufactured by a first step of seam welding the tube between two superposed bag walls. In a subsequent step, an encircling sleeve is slid over the tube to a position where it contains within it the portions of the bag walls on either side of the tube. Thirdly, this sleeve is compressed onto the tube by a crimping operation conducted with the crimping force applied in a direction substantially parallel to the plane in which the bag walls lie. The tube may be part of a tap or other outlet fitting such as a push-pull tap.
