Abstract: A toothbrush includes a head having multiple cleaning elements. One group of the cleaning elements is flexibly mounted on the head and another group may be fixedly mounted on the head. The flexibly mounted cleaning elements are attached to a flexible membrane so that the membrane is capable of flexing to alter its original orientation during use of the toothbrush and then recover to the original orientation randomly during use.

Abstract: The head of a powered toothbrush includes a first tuft block mounted for rotational oscillation about an axis generally perpendicular to the outer surface of the head, and a second tuft block having fixed bristles or bristles independently movable by being mounted on an elastomeric base. The second tuft block oscillates perpendicular to a longitudinal axis of the head and in an in and out direction perpendicular to the outer surface of the head. A third stationary block may also be mounted on the head of the powered toothbrush. The bristles on the first, second, and third tuft blocks may be of various lengths, colors and stiffness, and may be mounted perpendicularly to or at an angle to the outer surface of the head.

Abstract: A toothbrush includes a support member mounted on a first shaft in the head of the toothbrush. A carrier member is mounted on a second shaft to the support member. The support member is eccentrically mounted so that when its first shaft is rotated the carrier member is moved in an orbital path during the rotation of the support member. The carrier member is freely mounted on its second shaft so that during this orbital movement the carrier member rotates in a random manner. Cleaning elements such as bristles extend outwardly from the carrier member.

Abstract: A powered toothbrush refill head combines a typical round oscillating or primary tuft block which oscillates in a rotational manner with a secondary tuft block. The secondary tuft block may be oscillated in a rotational manner or may oscillate linearly back and forth in the same direction as the handle of the toothbrush. The secondary tuft block could be in the form of a pair of side by side plates mounted on the head adjacent to the round oscillating block. The invention could also be practice where the secondary tuft block is in the form of a plurality of sets of rows of bristles mounted for back and forth movement in a direction perpendicular to the handle.

Abstract: A toothbrush assembly comprises a toothbrush, a storage unit comprising an input, a memory for storing audio signals received via the input, and an output for transmitting or playing the stored audio signals.

Abstract: A package that demonstrates a functionality of a contained product that has a demonstration feature distinct from the contained product that changes from a resting state to an active state upon activation of the contained product is described. In at least one configuration the product is a power toothbrush. In various instances the demonstration feature may be a movable medium. Among other things the movable medium may be agitated in the active state or may comprise various substances including one or more of sand, glitter, particles, powder filaments or fiber. A method of demonstrating the aforementioned functionality of a product, such as a toothbrush, is also described.

Abstract: An electrically driven toothbrush has a brush holder that is arranged to rotationally vibrate and carry a number of bristles interspaced with arcuate membranes. The membranes serve to aid cleaning of the teeth and to polish the teeth surfaces during use of the toothbrush.

Abstract: A child's toothbrush includes a handle in the form of a child-safe, ventilated toy, such as a rocket or a vehicle, and contains a removable child-safe vehicle, figurine, other toy or sundry product therein, and wherein a toothbrush head may be detachable from the handle.

Abstract: A drive system for imparting motion to a treating implement such as a toothbrush or the like includes a cam rotatably driven around an axis of rotation by a motor. The cam has a closed loop cam track eccentric to the axis of rotation. A control member is disposed between the cam and the treating implement head. The control member has a control slot extending completely through the control member. A pivot member is located between the control member and the treating implement head. The drive system further includes a drive shaft with its drive end freely mounted in the cam track. The drive shaft extends through the control slot and through the pivot member with its driven end operatively connected to the drive connection of the implement head. As a result, when the cam member is rotated the direction of movement of the drive shaft is controlled by the drive shaft being confined for sliding movement in the control slot. The drive shaft is still capable of rotating because of its free mounting in the cam track.

Abstract: A toothbrush (10) is disclosed with soft fingers (16) mounted on the toothbrush head (14). During use of the tooth-brush the fingers move laterally relative to the axis of the tooth-brush thereby improving the tooth cleaning and gum massaging performance of the toothbrush. The lateral movement of the fingers is accomplished by relatively stiff ribs (24) which physically interconnect the fingers to flexible portions of the toothbrush head. The ribs translate flexure of the head into the lateral movement of the fingers.

Abstract: A powered toothbrush include a head containing a rotating or oscillating first bristle carrier and also containing a second bristle carrier movably connected to the head, which second bristle carrier may include elastomeric walls for enhanced cleaning and may include a weakened section to permit it to at least partially collapse during a brushing motion.
