Abstract
A system for selectively dispensing toothpaste from a flexible toothpaste tube includes a flexible boot having a flexible tube-receiving cavity and a boot nozzle with which an outlet of the toothpaste tube aligns. Pins are insertable into sleeves of the flexible boot and movable between open and closed positions for removal and insertion of the toothpaste tube. A presser engages the outer surface of the boot to selectively squeeze toothpaste from the toothpaste tube through the boot nozzle. A controller intermittently activates a driver which moves the presser along a track towards the boot nozzle to dispense a measured amount of toothpaste. Jaws are positioned adjacent to the boot nozzle for selectively opening and closing the boot nozzle. A timer and an adjustable volume dispensing dial control the amount of toothpaste dispensed.
