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

A fluid dispensing power toothbrush, comprising:

• a head portion which includes a brushhead;
• a handle portion which includes a housing, defining an internal space in which is located a drive system for moving the brushhead;
• a fluid system which includes a single, undivided fluid reservoir having a length and sufficient fluid therein for multiple uses and a fluid pump separate from the fluid reservoir which moves fluid in successive user-initiated actions from the single fluid reservoir to the brushhead, by operation of an actuation member portion of the fluid pump, wherein the fluid reservoir and the fluid pump are positioned along an outer surface of the housing of the handle in operation of the toothbrush;
• a cover member configured to overlay and mate with a portion of the housing of the handle and to overlay the length of the fluid reservoir and at least the actuation member portion of the fluid pump, forming an exterior surface of a lower portion of the toothbrush when the cover member is in a closed position, wherein the cover member is configured relative to the outer surface of the housing to define a space therebetween to accommodate the fluid reservoir when the cover member is in a closed position, and wherein the fluid reservoir is accessible for removal when the cover member is in its open position;
• and
• a connector assembly for movably attaching the cover member to the housing to permit the cover member to move between said open and closed positions.
