<p>The invention relates to a simple cylindrical-conical pipe piece and the procedure itself as a result of which disposable plastic bottles used for different drinks or other liquids can be shrunk to a fraction of their original size after use. The characteristic feature of the vacuum cleaner pipe piece (1) is that, the upper end (2) of it can be connected to the vacuum cleaner pipe (4), and its other lower end (3) can be fitted to an element of the neck part of the disposable plastic bottle (5) in a way that the air can be sucked out of the bottle through the piece, as a result of which the bottle shrinks to a fraction of its original size. The invention relates to the procedure used in the course of using the vacuum cleaner pipe piece for removing the air from the disposable plastic bottle (5) with the help of a vacuum cleaner and shrinking the bottle (5). In the first step of the procedure the cap (6) of the bottle (5) is screwed on loosely, nearly completely, as a result of which the cap (6) operates as a valve after the bottle (5) has been shrunk and seals the path through which the air could escape, and in this way the bottle (5) retains its smallest shrunk size.</p> |
