Abstract From the Canadian patent

A pocket or purse toothbrush has a reservoir of liquid dentifrice in the handle of the brush. The brush per se has an absorbent pad extending along the back from a position near the reservoir to adjacent the brush bristles. A valve between the reservior and the absorbent pad may be opened to saturate the pad with dentifrice, allowing tooth brushing without a supply of water and, if desired, in private even if away from home.
