Abstract
Abstract The invention relates to a disposable toothbrush device having two elements. The first element comprises a brushing member including (i) a brushing head having flexible bristles therein, (ii) a shaft carrying the brushing head at one end thereof, (iii) an attachment means affixed to the remaining end of said shaft remote from the brushing head, and (iv) a plurality of ribs provided on the shaft adjacent the brushing head for reinforcement of shaft to render the shaft relatively rigid with respect to the bristles. The brushing head, bristles, shaft, ribs and attachment means of the brushing member are formed from a plastic material as a unitary plastic molding. The second element consists of a hollow handle in which the brushing member is housed prior to use. The handle means has one closed end, and an openable end from which the brushing member is removable from its housed position to a second brushing position wherein the attachment means on the shaft is secured onto said handle in a reverse manner from that of its housed position.
