Abstract: Drivetrain assemblies for personal care devices to generate controllable power tapping motion alone or with controllable sweeping motion. The drivetrain assemblies include a drivetrain shaft at least partially contained within a body portion. The drivetrain shaft is further configured to engage a brush head member. Some drivetrain assemblies include a single actuator for generating periodic linear movement, wherein the drivetrain shaft transmits the linear movement to the brush head member via a pivoting motion and/or a translational motion. Other drivetrain assemblies include the actuator for generating periodic linear movement and a motor on the drivetrain shaft to periodically rotate the shaft about a central axis.

Abstract: The present disclosure relates a reclosure or zipper for a reclosable package or container, such as a plastic bag, wherein opening or closing the zipper causes an audible sound and a tactile feel. The reclosure or zipper is manufactured by an apparatus which includes a cutting wheel which is opposed to a pressure wheel. The cutting wheel includes cutting teeth spaced about its periphery. Interlocked zipper material is engaged between the cutting wheel and the pressure wheel to form indentations in the interlocked zipper, thereby resulting in audible and tactile feedback when the zipper is operated.
