The novel bellows pipe (1) for bottles, pots and cans makes it possible for the first time to pour liquids in or out without a funnel yet without spilling a drop. The bellows pipe (1) can be retractably welded into the thread (2) of plastic bottles or into an intermediate pipe in the form of a securing sleeve (8) which is secured to apertures of pots and cans. The bellows pipe (1) may be pulled out as far as necessary. It may, for example, be pulled out far enough to allow it to be bent and thus easily inserted into a filler aperture to which access is difficult. |
