v the crevice to resiliently engage the surfaces of the teeth defining the crevice. Thus. while the string or floss removes some particles. there is no assurance that it will essentially completely fill the crevice to physicaiiy and mechanically remove all the particles in the [IS-under tension produced by rollers [4 so that the yarn. between the point A at the rollers and the point B at the spool. is under a tension of l to pounds. The tensioncd yarn is guided through a bath of nylon resin dissolved in alcohol and then partially dried for thirty seconds by heat lamps 16. The yarn is then subjected to heat by a heater 1? for complete drying and pressure from a press 18. A portion of the yarn from the point A to the point C is notplaced under tension while it is being dried.
The yarn is continually processed to produce a continuous length of teeth cleaner shown in H0. 3. The
. points A and C are indicated where they will occur and crevice and to rub against and abrase the surfaces of a the teeth defining the cavity.
lt is an object of the present invention to provide 21 teeth cleaner which is capable of being as easily inserted into a crevice between teeth as dental floss but yet which is capable of essentially completely filling the crevices to assure complete removal of particles therein.
Another object of the present invention is to provide a teeth cleaner which has a portion which is formed to be of a diameter normally larger than the crevice but yet in which the spongy portion is resiliently compressible to enable it to adapt to the shape of the crevice. A further object of the present invention is to achieve the aboveobjects with a teeth cleaner that is economical. to manufacture and does not deteriorate with only a single use so that it may be used for numerous crevices. v r
In carrying out the present invention. the teeth cleaner herein specifically described consists of a plurality of elongate filaments or fibers that extend throughout the length of the cleaner. One portion of the filaments are formed to be a string portion by being essentially paralleland closely packed so that they in effect resemble conventional dental floss. The remaining portion of the filaments form a brush portion with V the filaments extending in the same direction as in the string portion but by being textured. i.e. randomly crinkled and commingled. the brush portion is thus spongy and of a larger thickness than the string portion. It is thus essentially elastic. capable of being easily reduced in diameter by a compression force or an elongating force but yet having memory which causes them to return to their normal bulky or crinkled state upon removul of the thickness reducing force.
Other features and advantages will hereinafter ap pear.
in the drawing:
FIG. 1 is a view of the teeth cleaner of the present invention.
FlG.2 is a diagrammatic 'view of one method of forming teeth cleaners.
FIG. 3 shows the manner of forming individual cleaners from the continuous length produced by the method shown in FIG. 2. a v
it will be seen that basically the points B and C correspond. The continuous yarn is then severed March of the points D to produce the individual cleaners 10.
It will be understood that the textured yarn on the spool 13 consists of perhaps 200 to 300 continuous fiIaments that were parallel and smooth but which have been textured by mechanical and/or heat treatments to permanently set or form coils. curves. twists. crimps and/or loops in the parallel filaments. Such yarn is generally commercially available with one or more fila ments and may be of the type disclosed in US. Pat. Nos. 2.919.524: 3.077.724 and 3.091.912. though. of course. the'invention is not to be limited thereto but includes textured and/or bulk. stretch yarns that have coiled. curled. crumpcd or loop distorted and commin gled filaments.
The stretching of the yarn between the points A and B causes the yarn to stretch and remove the set coils. crimp and/or loops so that the yarn that forms the string portion ll has its filaments become straight and parallel. The nylon resin from the bath coats the filaments and thus prevents them from becoming textured again upon release of the tension. The brush portion 12 is completely dried while under no tension so that it reverts to becoming textured again. Moreover. the nylon resin also coatsthc bulky brush portion to somewhat stiffen it and to give it more resistance to being compressed.
In use. the string-portion effectively acts as dental floss. permitting easy insertion past the contact point of the crowns bf adjacent teeth into the crevice between the teeth with the dislodgment of particles at the contact points. The string portion is then pulled. to cause the brush portion to enter into and pass through the crevice. The brush portion rubs against the sides of the teeth to be compressed to assume the shape of the crevice and as it is pulled through it dislodges particles therein between the gum line and the contact points. 7
The brush portion then after removal reverts to its initial noncompressed bulky shape to permit it to be used in the next crevice.
It will be understood that the brush portion is thus a spongy mass of textured nylon filaments which are held plied to a user. it is also contemplated that the teeth cleaners may be packaged as'a continuous strand. such as shown in FIG. 3 prior to severing. so that the cleaners are joined to each other with the user severing each cleaner from the length as is desired.
Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
