FIELD OF INVENTION
The Dental Floss Device generally relates to dental cleaning, more specifically dental flossing. The Device is designed to simplify the process of flossing and to make it more efficient.
BACKGROUND OF THE INVENTION
The three general methods of cleaning teeth utilizing dental floss (or, “flossing”) are: (1) A length of dental floss is cut from a roll, held in both hands by its ends and manipulated to clean the teeth; (2) A lengths of floss is stretched between two prongs of a c-shaped plastic frame with a handle which allows it to be manipulated by a single hand while cleaning teeth; and (3) a length of dental floss is attached to two handles of various shape which would allow for a more comfortable holding and operation of the floss.
The disadvantage of the first method is the necessity to place fingers inside one's mouth, which could introduce more germs from the fingers into one's mouth. Secondly, the cleaning is uncomfortable and deficient due to inability to fully reach back teeth. Finally, the first method causes the waste of floss.
The disadvantage of the second method is the constant tension applied to the length of dental floss, which does not permit effective cleaning around teeth, as well as, the inability to place the c-shaped frame in optimal position for flossing.
As to the third method, there is a number of patented devices utilizing two holder portions, sometimes even rod-like, connected by a piece of dental floss which did not find any substantial use in practice. The reason is that the devices proposed, for instance those disclosed in U.S. Pat. No. 4,342,324, U.S. Pat. No. 4,403,625, U.S. Pat. No. 5,174,314, and U.S. Pat. No. 5,911,229 have been designed in a manner that would neither produce a desired effect that is claimed in those patents, nor would be feasible in terms of production costs.
The present invention overcomes the disadvantages of the above methods by eliminating the necessity of placing finger into one's mouth, but, at the same time, by improving the ability to maneuver and to manipulate the floss, and allowing the application of the variable tension to a length of floss, which would allow effective cleaning. Moreover, the ability to manufacture the device very cheaply by injection-molding the rods together with the dental floss in one step makes the device economically feasible to produce.
SUMMARY
According to the invention, a small length of dental floss, measuring between 0.5 and 1.5 inch is attached by its ends to one of the ends of two separate rods. For the ease of understanding we chose to designate the ends of the rods to which the dental floss attaches as top ends, and the opposite ends of the rods as bottom ends. These rods shall measure not less than 2 inches in length. These rods will be easily manipulated inside the mouth by both hands, but without the need to place fingers into one's mouth. Variable tension may be applied to the length of floss as required for effective cleaning. Moreover, due to the fact that the ends of the rods may come very close to the teeth in any position in reference to one another, the floss is allowed to better loop around the tooth, to follow the curvature of the tooth, which causes it to better clean the tooth. In another embodiment of the invention, the device has a capability to utilize dental floss from a roll by quickly attaching the ends of a length of dental floss cut from a roll to two separate rods. In another embodiment of the invention the flossing is combined with tooth picking and (gum massaging) in the same operation.

DETAILED DESCRIPTION
Referring to the FIG. 1 of the drawings, there is illustrated a dental floss device according to the invention comprising a length of dental floss 1, the ends of which are connected to one of the ends of each separate rod 2. The ends to which dental floss connects we called the top end in our claims for the ease of understanding. The opposite end is called a bottom end for the same purpose. Rod is an elongated member of any shape known to men today or later invented, and may have specific shape for ease of use by blind people. Dental floss is either a thin nylon filament or a plastic (such as Teflon or polyethylene) ribbon used to remove food and dental plaque from teeth. The floss is gently inserted between the teeth and scraped along the teeth sides, especially close to the gums. Dental floss may be flavored or unflavored, and waxed or unwaxed. The length of the rods shall be not less than 1.5 inches. The length of dental floss shall be between 0.5 and 1.5 inches and shall be set to allow for comfortable manipulation of the floss inside the mouth by allowing for variable tension applied to the length of floss 1, and for comfortable insertion between the teeth. There is a lock 3 provided on one of the rods to connect the rods together for ease of storage.
Referring to FIG. 2 of the drawings, there is illustrated a dental floss device comprising of rods with handles 4 located on the bottom rod ends opposite to the top ends of the rods 2 to which the length of dental floss 1 is attached. The handles 4 are added to improve the device manipulation.
Referring to the FIG. 3 of the drawings, there is illustrated a dental floss device according to the invention wherein the top ends 5 of the rods 2 are gradually tapered to a very small point, which points are flexible and are connected by the length of dental floss 1, wherefore allowing tooth picking in conjunction with flossing. The tapered top ends 5 work as toothpicks during flossing. A toothpick is a small stick of used to remove food particles from the teeth, usually after a meal.
Referring to FIG. 4 of the drawings, there is illustrated a dental floss device according to the invention wherein the flexible top ends 6 of the rods 2 connecting to the ends of the length of dental floss 1 are gradually tapered to a very small point and have serrated surface wherefore allowing improved tooth picking in conjunction with flossing.
Referring to FIG. 5 of the drawings, there is illustrated a dental floss device according to the invention wherein the flexible top ends 7 of the rods 2 connecting to the ends of the length of dental floss 1 are gradually tapered to a very small point and are made from soft, flexible material with either smooth or serrated surface wherefore allowing improved tooth picking and gum massaging in conjunction with flossing.
Referring to FIG. 6 of the drawings, there is illustrated a dental floss device according to the invention wherein the flexible top ends 8 of the rods 2 connecting to the ends of the length of dental floss 1 are gradually tapered to a very small point and are made from soft, flexible material with protruding bristles wherefore allowing improved tooth picking and gum massaging in conjunction with flossing.
In all dental floss devices illustrated on FIGS. 3 to 6 the rods may be made with the handles 4 or without the handles. Handles may be made of various shape and size known now or to be invented in the future. An alternative embodiment of the invention is illustrated on FIGS. 7 to 10.
Referring to FIG. 7 of the drawings, there are illustrated rods 9 which may be used in conjunction with dental floss from a dental floss roll. The bottom ends of the rods 9 has a split 10 with the two halves of the split 11 & 12 immediately adjacent to one another and touching. One of the halves 12 is slightly longer than the other for the ease of the insertion of the floss. The ends of the length of dental floss 1 are inserted into the split 10 of the said rods and are wound a few times around each rod, this operation is repeated a few times. This part is designed to fasten the end of the dental floss securely in place and attached to one of the ends of each rod.
Referring to FIG. 8 of the drawings, there is illustrated part 13 located on the top ends of the rods 9. This part 13 is a hollowed top end of the rod 9 with a tapered through cut 14 in its wall. The walls of the cut protruding inside the hollowed top end as two touching wedges 15 creating a single wedge, and designed to trap dental floss when inserted into the cut and securing the inserted dental floss to the ends of said rods. This part of the device, in conjunction with the split 10 illustrated on FIG. 7, is designed to prevent the escape of dental floss from the top end of the rod 9. The wedges 15 are holding the floss inside the hollowed end by deflecting the floss away from the cut 14.
Referring to FIG. 9 of the drawings there is illustrated rod 9 with a flared bottom end 16, which has a split 17 and a floss stop 18, which prevents the floss from reaching the end of the split 17. There is a slide 19 sliding along the rod 9. Moving the slide 19 onto the flared end 16 traps the end of the dental floss inserted into the split 17 by squeezing the halves of the split 17 together.
Referring to FIG. 10 of the drawing there is illustrated rod 9 with a cross cut 20 in its body and a slide 21 sliding along the rod 9. When the end of dental floss 1 is inserted into the cross cut 20 and the slide is moved over the cut 20, the floss inserted into the cut is trapped when it is bent and squeezed between the slide and the rod.
Referring to FIG. 11 of the drawing there is illustrated a rod 9 attached to a roll of dental floss 22. The roll of floss 22 may be attached to either one of the two rods 9. The floss is extracted from the roll and is attached to the rods 9 as illustrated on FIGS. 7-10. Any rod type illustrated in FIGS. 7-10 may be used with a roll of dental floss.
In all dental floss devices illustrated on FIGS. 3 to 6 the flexible top ends of the rods may be manufactured from the same material as the rods, or from a different material.
