ABSTRACT:
The outlet tubes of pressurized cans containing, for example, polyurethane which is to be foamed, very frequently become clogged. The unconsumed residue of the substance intended to be dispensed consequently becomes unusable. This is prevented in accordance with the invention by the use of tubes which are sufficiently stiff to enable them to be folded back over themselves to form a solvent-tight pinch fold, in which folded-back position the tube is held by a holding device. In addition, the free end of the tube can also be closed.
