Personal care implement

Oral care implement

Toothbrush

A personal care implement includes a treatment device having a longitudinal axis and including a treatment portion having at least one treatment element; a connection portion having a main body and a first resilient snap attachment protruding from the main body, the main body formed of a first material having a first hardness and the first resilient snap attachment formed of a second material having a second hardness, the first hardness being greater than the second hardness; and the treatment device is alterable between: (1) a detached state; and (2) an assembled state in which the treatment device is detachably coupled to a grip section such that the first resilient snap attachment cooperates with and engages a first engagement portion of the grip section to secure the treatment device to the grip section.

Personal care implement with replacement head

A toothbrush includes a handle, a head at a distal end of the handle comprising a bristle plate, a hole extending through the bristle plate, a plurality of bristles at least partially disposed in the hole and extending from the hole in a direction away from the head, and a reservoir in fluid communication with the hole. Fluid in the reservoir enters the tuft holes and is wicked out of the head of the toothbrushes by capillaries formed between the bristles.

Brush with fluid delivery

A personal care implement that uses less plastic by removing material from a handle of the oral care implement while maintaining a comfortable grip which is similar to a normal grip that a user associates with a personal care implement. That is, the handle has a recess in a rear surface thereof, such that the handle or a portion thereof has a U-shaped transverse cross-sectional area. Portions of the handle may be covered with an elastomeric material to increase gripability and comfort. The handle may also include various rib structures elongated along the recess to increase the strength of the handle so that it does not significantly deform during normal use.

An oral care implement having a head and a handle. A plurality of tooth cleaning elements extend from an exposed front surface of the head. The handle has an open thumb gripping passageway extending between an exposed first surface of the handle and an exposed second surface of the handle opposite the exposed first surface. The handle also has a plurality of slots defining open slot passageways from the exposed first surface of the handle to the exposed second surface of the handle. The open thumb gripping passageway may be defined by a ring component that is fitted into an aperture in a body component. The open thumb gripping passageway may be a void space in the handle. The open slot passageways may be elongated along the handle and may serve to reduce a total amount of virgin material needed to manufacture the oral care implement.

An oral care implement herein may be embodied as an oral device for placement in the oral cavity. The device may include an insert configured for placement in the oral cavity in contact with a wearer's teeth and an activating member configured for placement in the oral cavity and selectively attachable to the insert.

Oral device with activating element

A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.
