Abstract: A foldable toothbrush is formed from front (2) and rear (4) parts that are hingeably connected. The front part, containing the brush portion (6), has a cavity (8) for storing toothpaste. The cavity communicates with the brush portion through holes (16). The rear wall of the cavity is a slide member (22) that can slidably move forward to compress the cavity and force toothpaste through the communication holes. The rear part has a thruster 36 that is connected to a pusher (40) and is slidably confined to a track (28, 30, 44). When the foldable toothbrush is unfolded, the user can engage pusher (40) to move thruster (36) into the front part to engage the slide member (22) to push toothpaste through holes (26). The pusher (40) can then be disengaged from the front part and the toothbrush can be folded.
