  • Patent number: 5174314
    Abstract: An oral hygiene device employs a hollow plastic tube sealed at both ends. At least one area along the length of the tube is weakened and has its diameter in the weakened area reduced, but not reduced to zero diameter. A length of fiber, such as conventional dental floss well known as a tooth cleaning material is stored within the length of the tube comprising the housing and has each of the free ends secured to a bulk of rigid material whose size does not permit the fibrous material from being able to escape the narrow diameter area. In use, a user bends the unbroken tubing housing to a point that the tubing breaks into at least two pieces, allowing the fibrous flossing material to be positioned intermediate the separated portions of the tubing, which are now free to act as handles. After its use, the fibrous material and the two handles may be discarded.

  • Patent number: 4836227
    Abstract: An oral hygiene device is comprised of a hollow housing having a weakened section in the periphery of the housing so that when the weakened section is broken, a user may grasp and separate the housing into two portions. A length of stretchable dental material and dentifrice is totally encased within a cavity in the unbroken housing and is secured at each end to two interior regions of the housing that can be separated at the weakened section. The length of the dental material is sufficient to allow the two portions of the housing to be grasped with opposite hands of the user and disposed in spaced apart relationship with each other, thereby permitting a portion of the dental material to be stretched uniformly in cross-section, by passing the dental material through small draw-like openings in each end of the housing so as to form a uniform and smooth exposed length of dental material and a quantity of the dentifrice which may be applied between adjacent teeth of the user, in conventional fashion.

  • Patent number: 4519408
    Abstract: An oral hygiene device is comprised of a hollow housing, having a weakened section in the periphery of the housing so that when the weakened section is broken, a user may grasp and separate the housing into two portions. A length of dental floss-like material is totally encased within a cavity in the unbroken housing and is secured at each end to two interior regions of the housing that are separated by the weakened section. The length of the dental floss-like element is sufficient to allow the two portions of the housing to be grasped with opposite hands of the user and disposed in spaced apart relationship with each other, thereby permitting the precoiled portion of the floss-like material to be straightened out and to be applied between adjacent teeth of the user, in conventional fashion.
