Abstract
A product-dispensing device includes a housing, an actuator, and a time delay mechanism. The actuator is supported by the housing for rotation about a first axis. The time delay mechanism is operably coupled to the actuator and includes a first gear, a second gear, a damper, and a biasing member. The first gear is fixed for rotation with the actuator. The second gear is supported by the housing for rotation about a second axis and configured to engage the first gear. The first gear is operable to rotate the second gear in a first direction about the second axis. The biasing member is operable to rotate the second gear in a second direction about the second axis. The damper is operable to control a rate of rotation of the second gear in the second direction about the second axis. The second direction is opposite the first direction.
