US 6,314,609 B1 · Mouth powered vacuum

Abstract

A mouth powered vacuum is provide with a cap with a lip at a lower end attached around a mouth of a bottle. The lip is made of a resilient material, so that it can be snapped on and off the bottle without twisting. A curved intake channel is connected between a side and a bottom of the cap. A flexible pickup tube is inserted into the intake channel at the side of the cap for being swept over objects to be picked up. A generally rigid mouth piece is integrally attached to the cap, and positioned sideward and upward for being sucked by a user. The angle between the mouthpiece and the bottle is selected to enable the bottle to be held comfortably when the mouthpiece is placed between the user's lips. A mouthpiece channel is connected between a distal end of the mouthpiece and the bottom of the cap. The inner end of the mouthpiece channel is enlarged relative to the outer end. A screen is positioned across the enlarged inner end of the mouthpiece channel for preventing the user from inhaling the objects. The screen is much larger than the outer end of the mouthpiece channel for improving airflow.
