US Patent 7896285 Sheet product dispenser

A dispenser for dispensing sheet product from a supply to a user is disclosed. The dispenser includes a feed device for dispensing a length of sheet product, an energy storage device in operable communication with the feed device, and a user interface in operable communication with the energy storage device. The user interface is biased in a first direction to a rest position by the energy storage device and is responsive to energy from the user to move in a second direction opposite the first direction and transfer energy to the energy storage device. The energy storage device is in operable connection with the feed device and applies the transferred energy to generate motion of the user interface in the first direction toward the rest position to actuate the feed device and dispense the sheet product.
