• a handle,
• a plurality of exchangeable toothbrush heads, each said head comprising a generally planar back plate in which a set of bristles is secured, said back plate having a pair of opposed edges which are profiled to complement corresponding opposed edges disposed on said handle, and
• a container for said heads,
• said handle being adapted for secure but releasable engagement with each of said heads,
• said container having a plurality of compartments arranged side by side, each of said compartments being adapted to hold one of said heads and adapted to permit engagement with each said head by said handle, said back plate of each said head being located by side walls of its respective compartment, engagement being effected by relative movement of said handle and said head in planes parallel with that of said back plate, each of said compartments having an opening at one end thereof, said handle being insertable through said opening of each compartment to engage said head therein and withdraw said head from said compartment secured to said handle,
• whereby to remove said head from said container by means of said handle.

A toothbrush system comprising

• a handle
• said handle having a bifucated forward end portion defining a pair of generally parallel arms having confronting inner surfaces, said arms being resilient to permit separation thereof,
• a plurality of exchangeable toothbrush heads,
• each of said heads comprising a generally planar back plate in which a set of bristles is secured, said back plate having a pair of opposed edges which are profiled to complement corresponding opposed edges on said handle, and
• a container for said heads,
• said container holding said heads and adapted to permit engagement with said handle,
• said handle being adapted for secure but releasable engagement with each of said heads in turn, engagement and disengagement being effected by relative movement of said handle and said head in planes parallel with that of said back plate, resilient detent means being provided to secure said head and handle together when said back plate is fully inserted between said arms,

• a plurality of exchangeable toothbrush heads,
• each of said heads comprising a generally planar back
• plate in which a set of bristles is secured, said back plate having a pair of edges which are profiled to complement said opposed walls on said handle, said opposed walls and said edges having cooperating guide rails and recesses thereon, and
• a container for said heads
• said container having a plurality of compartments, each compartment being adapted to retain one of said heads therein, the compartment being open from above and one end, said back plate having an upper surface and said edges exposed for engagement from above by said handle,
• said handle being adapted for engagement with said upper surface of said back plate and rotated to engage said opposed walls of said handle with said end edges of said back plate,
• whereby to remove said head from said container by means of said handle through said open end of said compartment.
