Abstract
A disposable toothbrush, comprising a first section (12) having a first proximate end (16) and a first distal end (18), a second section (22) having a second proximate end (28) and a first distal end (25), a plurality of bristles (20) coupled to the first distal end (18), a plug (30) sealingly disposed within the second section (22) and thereby forming a compartment (26) within the second section (22) between the plug (30) and the second proximate end (28), a quantity of powdered dentifrice disposed within the compartment (26) and a sealing means (32) sealingly disposed on the second proximate end (28) in order to seal the compartment (26) wherein the first proximate end (16) has a smaller cross-sectional dimension than the second distal end (25) so that the first section (12) may be placed in frictional, sliding engagement with the second section (22) when the first proximate end (16) is inserted into the second distal end (25).
