11 Claims, 16 Drawing Figures PATENIEDnEc 18 1915 3,779,256 SHEET 1 (1F 2 INVENTORS ALBERT L. MALONEY BY HOLLY H. MALONEY GEORGE F. BETHEL ATTORNEY ORAL IIYGIENIC DEVICE BACKGROUND OF THE INVENTION stantially overcome by this invention.
Toothpicks have been used to remove certain extraneous deposits between teeth, but have not effectively caused a cleaning action when driven between two adjacent teeth. Furthermore, toothpicks of the prior art are generally made of wood or improperly formed plastic which causes the gums to bleed. Additionally, they have not been of sufficient strength to provide a continued cleaning action once placed between the teeth.
In addition to the foregoing deficiencies of toothpicks, a main deficiency revolves around the fact that the picks do not scrub the residue or extraneous buildup from the teeth nor effectively scrape material therefrom. This invention has substantially overcome such deficiencies and provides an improved oral hygenic device which serves to remove extraneous material.
In addition to the foregoing advantages of this invention, the oral hygenic device can incorporate a hook. The hook in one embodiment of this oral hygenic device enables one to lead a length of dental floss through the space between a bridge and the gum. Furthermore, it allows the threading of dental floss to other areas which enables one to clean those areas with the floss once it it threaded therethrough. In prior art devices, small holes were sometimes provided for receiving floss, as in a needle, or no means at all was provided. This made the threading of floss between a bridge tooth and gum quite difficult, causing one to thread the floss in whatever manner he could.
It is common for food debris and bacterial plaque to build up on teeth after an extended period of time if the teeth are not scraped. This invention incorporates a relieved scraping means not known in the art for scraping such residue from the teeth.
This invention substantially overcomes most of the prior art drawbacks by providing a superior oral hygenic device for preventive dentistry purposes. Furthermore, the oral hygenic device hereof provides many features to enhance the use of care for ones teeth and maintain them in an improved state of healthmess.
SUMMARY OF THE INVENTION In summation, this invention provides an improved oral hygenic device.
Specifically, the oral hygenic device hereof enables one to thread dental floss in a substantially easier manner than in the past. Furthermore, the device is shaped in such a design as to allow placement thereof within the teeth in a non-irritating manner. Also, the oral hygenic device incorporates relieved portions which scrub food debris and bacterial plaque from the teeth in a non-irritating manner to prevent substantial buildup thereof.
This invention bridges the gap between existing oral hygenic devices so as to enable one to systematically utilize a toothbrush, dental floss and the oral hygenic device hereof to provide a well-rounded cleaning and preventive dentistry program for one's mouth.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One can use the oral hygienic device of this invention generally shown by 10 in FIG. 1 by emplacing it between two adjacent teeth 12 and 14 and gripping the device with ones hand 16. FIG. 2 specifically shows a bridge cleaner 18 of this invention with a loop of dental floss 20 passing through a space 22. The space 22 lies between a gum 24 and a false bridge tooth 26 bridged between two adjacent teeth 28 and 30. The dental floss 20 serves to clean the space 22 between the bridge tooth 26 and the gum 24 in a gentle yet firm and effective manner.
It should be appreciated that inasmuch as the bridge tooth 26 is supported by the teeth 28 and 30 ,that an interface 32 and 34 between the respective teeth will not permit the passage of dental floss 20 therebetween. This is because clasps, or cement is used to emplace the tooth 26 between the teeth 28 and 30. Thus, the only way to clean the space 22 is to actually thread a piece of dental floss or a bridge cleaner as generally shown by the numeral 18 through the space 22 and work one or both within the space 22.
The bridge cleaner 18 which is shown in greater detail in FIGS. 8 through comprises an elongated body portion 38 tapering to a thin rounded end 40, with a hooked end 42 in distal relationship therefrom. The hooked end 42 has a hook 44 which forms a space 46 opening outwardly in part at an opening 48. The hook 44 receives the dental floss as shown in FIG. 2 by merely sliding the dental floss in a looped manner along the raised surface 50 of the oral hygienic device and allowing it to be caught in the opening 46. This effec tively creates a fast and fascile means for retaining the dental floss within the opening 46 of the hook 44. The raised surface is specifically raised above the level of the hook 44 so that the hook will not snag a user when the device is passed through the space 22. Preferably the hook 44 should not extend above the level or elevation of said surface 50 when it is under tension from floss placed therein. This avoids pulling of the users gum.
The oral hygienic device shown in FIGS. 8, 9, 13 and 14 specifically incorporates a cross hatched section 54. The cross hatched section 54 is formed from contiguous X-shaped lines which are analagous to those of a file. The foregoing cross-lined configuration 54 is such that the cross hatching comprises raised lines 56 which are criss-crossed, leaving spaces 58. FIG. 13 shows the crossover point 60 and the extremeties of lines 62 which comprise the filing portions and form a space 64. As can be appreciated, the abrading file action is effective for helping to remove bacterial plaque, food debris and residue which tends to build up on ones teeth.
The relieved portion 54 can be made up of cross hatched lines either impressed within the oral hygienic device or raised therefrom. However, any suitable relieved configuration will work if it provides the desired end result of a filing or gentle abrading action.
The round tapered end 40 of the embodiment shown in FIGS. 8, 9, l3 and 14 incorporates a narrowed portion which tapers inwardly from the full width of the elongated member 38 at approximately point 72. The oral hygienic device is provided with a blade having a hollowed or curved portion 74 which curves concavely into a reduced edge 76 for scraping purposes. Thus, when the initial rounded end 40 is inserted within the space between ones teeth, the entire oral hygienic device can be rotated to cause the reduced portion 76 or knifelike blade to scrape adjoining areas.
The foregoing knifelike edge 76 can be hollowed as shown by the curved portion 74 or may be tapered in any suitable manner as long as it provides the reduced knifelike edge 76. As will be described, alternative embodiments can utilize a tapered edge of any suitable configuration. Regardless of the configuration, the end result should be that the tapered edge or blade of this invention scrapes bacterial plaque or food debris from the teeth.
A second alternative embodiment generally shown in the drawings of this invention incorporates the embodiment shown in FIGS. 10, 1 1, l2 and 15. In this embodiment the hook 44 is utilized with its opening 48 leading to the space 46 for holding a length of dental floss 20 therein. The hook end 42 may be generally utilized in the manner shown in FIG. 2 as previously described. However, it should be noted that the embodiment of this invention incorporates stippling 80 which is of a raised character having a substantial number of individual protuberances 82 along the surface thereof. In
other words, the intermediate section of the embodiment shown in FIGS. 10, 11, 12 and 15 incorporates a series of raised protuberances which may be of any suitable shape as long as they effectively provide spaces 84. For example, the protuberances 82 should act as a scrubbing or abrasive means.
Although the raised protuberances have been defined, it should be noted that any relieved surface can be used so long as it provides gently abrading action.
In the embodiment shown in FIGS. 10, ll, 12 and 15, the rounded portion 40 tapers backwardly toward the stippling or protuberances 82 to form a bilaterally symetrical curvilinear portion 86 on both sides of an end segment 88. The end segment 88 is suitably formed so that the taper has an inwardly formed arcuate portion 86 and 87 on either side of the member 88. However, the base or lower section 90 of the member is curved upwardly to a reduced edge configuration 92 which can be utilized to scrape bacterial plaque or food debris from or between a users teeth.
Specifically, the device can be implaced at the reduced end 40 between the users teeth to a sufficient degree to allow rotation of the device so that the reduced edge 92 removes bacterial plaque. As the device is inserted further, the protuberances 82 can be utilized to gently abrade and remove bacterial plaque or residue which has been partially scraped and is ina loosened condition.
The foregoing two specific embodiments provide a knifelike scraping for generally loosening and scraping bacterial plaque as well as a substantially improved scrubbing or gentle abrading action by the relieved portions of the protuberances or stippling.
Another alternative embodiment of this invention incorporates the oral hygienic device shown in FIGS. 3, 4, 5, 6 and 7. The device shown therein is formed generally with an elongated portion incorporating a mid-section 102, a distal rounded end 104 and a handle end 106. The handle end 106 is reduced by inwardly curving portions forming the concave rounds 108 and is provided with raised stippling 110 having spaces 112 therebetween. The handle end 106 is shaped in a manner whereby it can be implaced in the sulcus or furrow between a users teeth. In this manner, the handle end 106 can be used to force food debris from ones teeth. Furthermore, the stippling 110 helps to remove bacterial plaque.
The oral hygienic device has a bladelike reduced edge portion 114 which terminates in a rounded end 104. The blade portion 114 has an upper reduced blade edge 1 l6 and a lower expanded portion 1 18. The blade is provided with stippling having spaces 122 therebetween. The stippling '120 is such that it serves to scrape the residue from a users teeth. The reduced or bladelike portion 116 is placed into a space between a users teeth at a sufficient point to be rotated. This causes the reduced section 116 to scrape any adjacent bacterial plaque or other residue on the teeth.
The foregoing combined features make this device substantially unique over the prior art. Not only is the stippling of a substantially improved type, but the reduced bladelike portion 116 serves to effectively scrape any residue or plaque on the teeth.
Altemative embodiments and features may be incorporated which fallwithin the teachings of this invention. Thus, this invention is only to be construed and read in the light of the following claims which define the scope and breadth of the invention.
