Abstract
Disclosed is a sanitary or no-touch dispenser which dispenses sheets of a web material, such as a paper towel. The disclosed dispenser provides the web material to a user by using both manual and electronic means to dispense the sheet. This is accomplished by having a motor engagably connected to an actuator roller. The motor is activated by a motor activation means, such as a switch. The motion of the actuator roller, which is started by the user grabbing and pulling a tail of the web material extending from the dispenser, causes the motor activation means to activate the motor which in turn drives the actuator roller to continue it its rotation motion to dispense the sheet from the dispenser.
Claims22
A dispenser for dispensing sheets from a roll of a web material comprising:
- a housing which forms a compartment;
- a holder for supporting a roll of a web material within the compartment;
- a cutting blade contained within an actuator roller, the actuator roller having a rotational path, the cutting blade being extendable from the actuator roller at a first predetermined location in the rotational path of the actuator roller and retractable at a second predetermined location in the rotational path of the actuator roller, wherein the cutting blade is extended from the actuator roller to cut the web material to form a sheet of the web material to be dispensed from the dispenser;
- a motor engagably connected to the actuator roller;
- a motor activation means, wherein the motor activation means activates the motor at or near the first predetermined location of the rotational path and deactivates the motor at or near the second predetermined location of the rotational path.
A dispenser for dispensing sheets from a roll of a web material comprising;
- a housing;
- a compartment positioned within the housing;
- a holder for supporting a roll of a web material, the holder located within the compartment;
- a dispensing actuator roller rotatably mounted within the compartment, the actuator roller having a rotational path and a rest position;
- a cutting blade mounted within the actuator roller, wherein the cutting blade cuts the web material at a predetermined location in the rotational path of actuator roller, and the cutting blade cuts the web material to form a sheet of the web material to be dispensed from the dispenser;
- a motor engagably connected to the actuator roller;
- a motor activation means to activate the motor, wherein the motor activation means activates the motor at a first predetermined location of the rotational path of the actuator roller between the rest position and the predetermined location in the rotational path of the actuator roller in which the cutting blade cuts the web material and deactivates the motor at a second predetermined location of the rotational path of the actuator roller at or before the rest position,
- wherein the first predetermined location in the rotational path of the actuator roller is between one-quarter and one-half of one full rotation of the actuator roller from a rest position and the second predetermined location is between one-third of one full rotation of the actuator roller and one full rotation of the actuator roller from the rest position.
