A reservoir toothbrush has a neck and a bristled head 1 that receive paste from duct 3. The handle 10 houses a release valve 5 that is a supply connection for a toothpaste container 6. The paste 11 is forced from within the container 6 by various devices including a manual plunger 7-9, or by the container being pressurised internally. The paste 11 may also be squeezed directly from a pliable handle 10, allowing a hollow paste filled handle to be provided. Brushes nay be refilled using replaceable containers 6 or wholly disposed of. |
