Abstract
Abstract A protective cover for a toothbrush, the cover being intended for use once only. The cover has one part adapted to enclose a part of the toothbrush handle and another part adapted to enclose the toothbrush head. That part of the cover surrounding the brushing head is, if required, also constructed with brushing means having a continuous brushing surface. A cover formed in this way can also be used in combination with an ordinary toothbrush, or with a toothbrush whose brushing head comprises a suitable soft member. That part of the cover which surrounds the brushing head is substantially secured against movement relatively to the brushing head.

A disposable cover adapted to be fitted to a toothbrush wherein said toothbrush has a brushing head and a handle; said cover comprising a substantially tubular member of flexible sheet material having an open end adapted to extend along the handle of said toothbrush and a closed end adapted to extend and surround the brushing head carried by the handle of the toothbrush; said cover being constructed to fit against a toothbrush in such manner that during brushing the teeth with the cover in position, that part of the cover which is adapted to encase the brushing head is substantially secured against movement relative to the said brushing head; said flexible tubular cover being formed of flexible polymer material having at least some elasticity; and the surface of that portion of the cover which is adapted to surround the brushing head having surface irregularities which increase the brushing efficiency of the brush when the cover is in position; said tubular cover being so arranged that the part of the cover which extends along and encases the toothbrush handle is turned inside out on removal of the cover from the toothbrush by drawing the open end toward the closed end; and additional means connected to and through said open end of said tubular cover for facilitating the turning of the cover inside out so that bacteria on the outside of the used cover are thus contained within the reversed cover; said additional means comprising an elongated flexible member secured to the interior of the cover and extending substantially the whole length and through the open end thereof.
