<p>PROBLEM TO BE SOLVED: To vacuumize a PET bottle and compress by outside atmospheric pressure by tapering the tip of a suction opening and making the pointed halfway portion of the tip contact the tip of the mouth of the PET bottle. SOLUTION: The tapered portion of an insertion portion 1 is inserted into the mouth of a PET bottle 3, and by making the tapered halfway portion contact the mouth of the PET bottle 3, linear contact occurs, thus improving airtightness. The suction opening is connected to the hose 5 of a vacuum cleaner and sucked by the vacuum cleaner, the interior of the PET bottle 3 is vacuumized and compressed by external atmospheric pressure. Therefore, an empty beverage PET bottle 3 can be compressed thinner by using a home vacuum cleaner. Therefore, more PET bottles can be put in a waste bag, waste bags can be saved and the place for storage until waste is collected can be reduced.</p> |
