The present invention relates to an electric toothpaste dispenser which seeks to overcome the drawbacks of such dispensers of the past which provided an imbalanced or uneven squeeze across the toothpaste tube and poor alignment of the tube and the rollers of the drive assembly. The present invention overcomes these drawbacks by including a rack (242) and a long screw (240) which provide an even, properly controlled squeeze on the tube and pliable rollers (263, 264) which apply a balanced and even squeeze across the tube. The dispenser includes a housing (212) having a nozzle clearing and automatic activating assembly (280, 285) and an adaptable grasping assembly (290) for holding the tube. A drive assembly (230) is mounted within the housing and drives a carriage (260) for queezing along the length of the tube. A control system activates the drive assembly and its automatic reversal. |
