Abstract: A flossing device comprising a floss carrying member having a hollow interior and a locking member receivable in the interior of the floss carrying member so as to be coaxially rotatable therein. The floss carrying member is adapted to support a span of dental floss. The locking member has an aperture therein through which the dental floss passes in an operative position of the locking member and the floss carrying member has an aperture therein, the arrangement being such that the aperture in the floss carrying member aligns with the aperture in the locking member in an operative arrangement of the two members. The apertures are such as to permit the floss to be introduced from the exterior of the floss carrying member into the aperture in the floss carrying member by laying the floss crosswise in said aperture from where the floss may be advanced, crosswise, into the aperture in the locking member.

Abstract: A device for cleaning teeth of the kind known as a dental floss holder comprising a housing adapted to house a quantity of dental floss, a locking member having at least one aperture therein and a formation adapted to support a span of the dental floss. The device has at least one aperture therein (but preferably two) such that the floss in an operative arrangement of the device passes through the aperture in the device, thereafter forms the span and then passes through the aperture in the device, the arrangement being such that the floss passing through the aperture in the device also passes through the aperture in the locking member when the latter is in an operative position.
