A brush arrangement, specifically a toothbrush, is provided with a reservoir of cleaning material in its handle. The handle is hollow and provided with an actuatable plunger arrangement which pressurizes the cleaning material so as to force it through a channel and to the brush head. The pressurized cleaning material opens a pressure valve arrangement which exposes a dispensing port through which the cleaning material is dispensed in the vicinity of a plurality of bristles. The dispensing port is opened by the application of a force from the pressurized cleaning material which exceeds a counterforce applied by a resilient device, such as a spring. When the pressure in the reservoir is relieved, such as by reversing the direction of travel of the plunger, the counterforce applied by the spring is sufficient to ensure that the pressure valve closes the dispensing port. In certain embodiments, the brush arrangement is provided with a replaceable brush head. Also, cleaning material can be supplied to the brush arrangement by inserting refill cartridges which can be made disposable.

A brush arrangement having a brush head with a plurality of bristles thereon, the brush head further comprising: reservoir means adapted for storing a fluid, said reservoir means being provided with an end stop and coupled to the brush head whereby said fluid is dispensed in the vicinity of the brush head; channel means interposed between said reservoir means and the brush head for providing a flow path therebetween for said fluid; actuator means having a first portion for manipulation by a user, and a second portion for communicating with said fluid in said reservoir means and being displaceable in response to said manipulation of said first portion for applying a pressurizing force which pressurizes said fluid, said pressurizing force being responsive to a displacement of said second portion, said second portion cooperating with said end stop of said reservoir means for reducing a dimension of said second portion whereby a remaining portion thereof having a reduced dimension is urged through a portion of said channel means in response to said manipulation; and pressure valve means arranged in the vicinity of the brush head and responsive to said pressurizing force applied by said second portion of said actuator means for opening a port whereby an amount of said fluid responsive to said displacement of said second portion of said actuator means is dispensed.
