A fluid-dispensing power toothbrush which includes a handle portion with a housing, a head portion and a fluid delivery system. The fluid delivery system includes a fluid reservoir and a fluid pump which are positioned to extend substantially along an outer surface of the housing of the handle portion. A cover member is pivotally attached to the housing and is configured to overlay and mate with a portion of the housing to form the exterior surface of a lower portion of the toothbrush when the cover member is in a closed position.

Cover structure for enclosing a removeable fluid-dispensing reservoir between the cover and an exterior surface of a toothbrush

The fluid-dispensing power toothbrush includes a selected toothbrush architecture, generally, a handle portion, a head portion which is removable from the handle portion and a fluid-dispensing system which is removable with the head portion. The fluid-dispensing portion includes a pump and a fluid reservoir, with the reservoir being removable from the pump. The entire reservoir extends down along an exterior surface of the handle, below the lower edge of the head portion. A cover member overlies and mates with the handle, covering the reservoir when the cover member is in a closed position.

Structural arrangement for a fluid-dispensing power toothbrush

The attachment system includes a brushhead assembly having a spring/carrier combination which comprises a spring assembly and a separate carrier assembly, adapted to mate as a combination with a receiving portion, in the form of a cup member, at the top of the handle of the toothbrush. The spring/carrier combination includes a slot which mates snugly with a vertical rib on the inside surface of the cup member, and further includes a portion which opposes the slot on the spring/carrier combination which mates snugly with a cut-out portion in the cup member, to prevent rotational movement of the brushhead relative to the handle. The spring/carrier assembly further includes two opposing spring finger elements, wherein the lower ends of the spring fingers fit into corresponding openings in opposing sides of the cup member when the spring/carrier assembly is operatively positioned in the cup member, tending to prevent translational movement of the brushhead relative to the handle.
