  • Patent number: 5195659
    Abstract: An automatic toothpaste dispenser is disclosed which forces a discreet amount of toothpaste from a tube by moving a plunger in a downward direction. The toothpaste dispenser has two halves which are hinged at the top to allow the tube of toothpaste to be inserted in the device. The front of the device has a plunger which activates two rear rollers inside the device which move downwardly to squeeze toothpaste out of the tube. The front plunger is attached to a front inner mechanism having engaging teeth. The inner mechanism slides on pins which are inserted into grooves. The grooves allow the inner drive mechanism to move down until the lower pins of the drive mechanism engage a guide which pushes the drive mechanism forward to engage corresponding teeth on the rear housing containing the rollers. A spring always brings the front inner drive mechanism back towards the top of the case.
