Abstract: 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.

Abstract: An oral care implement handle or a refill head therefor. The refill head may include a sleeve portion extending from a proximal end to a distal end, the sleeve portion having an inner surface that defines an internal cavity. The internal cavity may extend along a sleeve axis from an open bottom end at the proximal end of the sleeve portion to a closed top end, the internal cavity being configured to receive an attachment portion of a stem of an oral care implement handle. The internal cavity may have a proximal section adjacent the open bottom end and a distal section adjacent the closed top end. The distal section of the internal cavity may include a central portion located on the sleeve axis and at least one slot portion radially extending from the central portion.

Abstract: An oral care implement including a handle and a replacement head that is detachably coupled to the handle. The oral care implement may include a handle having a longitudinal axis that includes a gripping portion and a stem extending from the gripping portion. The gripping portion may have a shoulder that circumferentially surrounds the stem and an annular rib protruding from the shoulder. The replacement head may have a sleeve portion terminating in a proximal edge that is formed from a resilient material. The replacement head may be detachably coupled to the handle so that the annular rib of the shoulder and the proximal edge of the sleeve portion that is formed of elastomeric material are in contact with one another.

Abstract: An oral care implement, such as a toothbrush, that comprises a mirror and a light pipe adjacent the mirror. In one embodiment, the invention can be an oral care implement comprising: a body comprising a handle portion and a head portion; a mirror coupled to the body; a light source coupled to the body; and a light pipe coupled to the body and surrounding at least a portion of the mirror, the light pipe operably coupled to the light source to distribute light emitted by the light source through the light pipe.

Abstract: An oral care implement handle or a refill head therefor. The oral care implement handle may include a gripping portion and a stem protruding from a shoulder of the gripping portion. The stem may include a post located at a distal end of the stem. The post may have a non-circular transverse profile. More specifically, the post may include a hub portion and a protuberance that either protrudes radially from a side surface of the hub portion, protrudes upward from the shoulder of the gripping portion, or both. The refill head may include a sleeve having an inner surface that defines an internal cavity. The internal cavity may include a central portion and at least one slot portion extending radially from the central portion. Thus, the internal cavity of the sleeve portion may have a profile configured to receive the stem of the oral care implement handle.

Abstract: An oral treatment device that emits electromagnetic radiation onto surfaces of a user's teeth. The oral treatment device may include an intraoral mouthpiece and a handle extending therefrom, the handle containing the control circuitry required for operation of the device. The mouthpiece may include a lamp support structure, a lamp, a lens plate, and a guard component. The lamp may include an electromagnetic radiation source that includes a flexible sheet and a plurality of illumination elements located thereon. The illumination elements may be light emitting diodes printed with an electrically conductive. Additional electronic components such as a processor and a power source may also be included in the device.

Abstract: In some embodiments, an oral care implement includes an elongate body extending from a proximal end to a distal end, a head disposed at the distal end of the elongate body, a plurality of bristles disposed at the head, a speaker, a sound chamber, and a water impermeable membrane. The speaker is disposed in the elongate body to emit sound corresponding to audio received from an audio source. Speakers disposed in a distance spaced from the proximal end of the elongate body and is configured to emit sound toward the proximal end of the elongate body. The sound chamber includes an elongate internal space extending from the first opening proximate the speaker the second proximate the proximal end of the elongate body. Sound emitted from the speaker passes through the sound chamber. The water impermeable membrane occludes the sound chamber between the speaker and the proximal end.

Abstract: An oral care implement including a handle and a replacement head that is detachably coupled to the handle. The handle may include a gripping portion extending from a proximal end to a distal end and a stem extending from the distal end of the gripping portion. The stem may have an inner cavity. A vibratory element including a motor and an eccentric may be partially located in the stem. The eccentric may have a first end that is operably coupled to the motor and a second end opposite the first end, the second end having an aperture therein. A guide pin may be fixed to the stem such that a first portion of the guide pin protrudes into the inner cavity of the stem. The first portion of the guide pin may extend through the aperture in the second end of the eccentric.
