Definitions
- the present invention relates to a length of yarn which is used like dental floss for insertion into crevises formed between adjacent teeth to clean the crevices.
- the adjacent crowns of the teeth forming the crevice are quite close together, if not touching, and the cleaner to be effective must pass through the adjacent crowns into the crevice.
- the cleaner if small enough to be capable of passing past the crown, is not large enough to essentially fill the crevice to enable effective cleaning action by the removal of particles therein and the scrubbing of the crevice forming surfaces of the adjacent teeth, while if large enough to effectively clean the teeth, will not pass through the crowns.
- Another object of the present invention is to provide a teeth cleaner which may be easily inserted into the crevice past theclose crowns by having its thickness decreased, but yet revert to an enlarged bulky state in the crevice to substantially fill the crevice so as to engage the surfaces of the teeth forming the crevice.
- a further object of the present invention is to provide a method for making a continuous length dental cleaner from a length of textured yarn which achieves the above objects and in which the bulkiness of the cleaner is increased over that which the yarn originally possessed.
- the interdental cleaner consists of a continuous length of textured yarn that has been coated with a hardened resin to increase its stiffness and memory.
- a hardened resin to increase its stiffness and memory.
- the yarn filaments are covered with a hardened covering, such as nylon resin.
- the process of making the cleaner not only involves providing the hardened covering but also includes the step of increasing the bulkiness of the yarn. This is achieved by exerting an elongating force on the yarn that tensions the yarn and causes the filaments to become somewhat less entangled after a removal of the tension so that the normal and inherent bulkiness of the yarn is increased.
- the covering may be applied as a liquid during the tensioning or after and then hardened with the hardening occurring while substantially no tension is exerted on the yarn and thus the covering serves to maintain the increased bulkiness thereof.
- a desired length of cleaner is severed from a continuous supply thereof and the user stretches, by tensioning, a short portion between his fingers which minimizes the thickness of the cleaner. This stretched portion is passed through the contact points at the crowns of adjacent teeth defining the crevice and into the crevice. The tension is then released which enables the cleaner to assume its normal bulky state wherein it substantially fills the crevice.
- One end of the cleaner is then pulled, to draw the clenaer through the crevice and in so doing, cause dislodgement of particles therein while also tending to scrub the surfaces of the teeth defining the cavity.
- FIG. 2 is a representation of a length thereof.
- FIG. 3 is a view showing the applying of an elongating force to reduce the diameter of the cleaner for insertion past the crowns.
- the continuous length of interdental tooth cleaner of the present invention is generally indicated by the reference numeral 10 and is wound as a continuous length on a spool 11 after being formed by the process that includes the apparatus shown in FIG. 1.
- a strand of continuous length 600 denier textured yarn is drawn from a spool 12 through a squeeze block 13 by a set of rollers 14.
- the yarn between the squeeze block 13 and the rollers 14 is stretched by a tension of perhaps 3 pounds.
- the yarn is then sprayed by a sprayer 15 with nylon resin that is dissolved in a solvent such as alcohol so that the filaments of the yarn become covered with the liquid.
- the solvent is evaporated by use of a heat dryer 16 which by eliminating the solvent causes the nylon resin to form a hardened covering on the filaments.
- a pair of feed rollers 17 draws the yarn through the sprayer l5 and the dryer 16 after which it is subsequently wound on the spool 11 as the continuous length interdental teeth cleaner.
- the rollers 14 and 17 are preferably mechanically interconnected with the rollers 17 being driven at a slightly lesser rate than the rollers 14.
- the lesser rate is such as to exert substantially no tension on the yarn between the rollers which enables the yarn to contract to a shorter length than it had when withdrawn from the spool 12.
- its bulkiness is greater.
- the spool 11 winds the cleaner 10 without any substantial tension thereon so that the cleaner on the spool 11 is at its normal bulky state.
- a user cuts the desired length of the cleaner 11) from the spool 11 and places a portion thereof, such as a portion 18, between the fingersand exerts a pulling force thereon as shown in FIG. 3, which substantially reduces the thickness of the yarn by basically straightening the filaments to eliminate the deformities of the filaments that cause the yarn to be textured.
- the portion 18 is then easily inserted through the contact point at the crowns of the teeth in the same manner as normal straight filament dental floss. The user thereupon releases the tension and the cleaner assumes its normal bulky condition as shown by the portions thereof that are not under tension.
- a slight pull on the end of the cleaner draws it through the crevice and as it is in its normal bulky condition, it substantially fills the crevice to dislodge any particles of food while also exerting a cleaning action on the surfaces of the teeth defining the crevice.
- FIG. 4 Shown in FIG. 4 is another embodiment of the present invention in which the liquid resin is contained within a bath 19 located between the rollers 14 and the squeeze roll block 13.
- the yarn is immersed in the bath 19 to have its filaments coated. It may then be either passed beneath the sprayer 15 for additional contact with the liquid resin or not and then passed through to the dryer 16 to cause evaporation of the solvent.
- the tension on the yarn at the dryer is less than the tension between the rollers 14 and the squeeze block 13 and preferably essentially no tension exists so that the yarn, while having its nylon coating hardened, will be in a relaxed state and thus will have an increased bulkiness over that which the yarn has when drawn from the spool 12.
- the bulkiness is caused by the filaments becoming somewhat less entangled after being stretched and the hardened covering maintains this state of a larger diameter or bulkier cleaner 10.
- the hardened covering still enables a tension to produce a small diameter straight portion, such as the portion 18 for easy insertion into the crevice.
- an interdental tooth cleaner which may be formed as a continuous length of textured yarn that has had its filaments covered with a hardened covering.
- the user severs a desired length of the cleaner from a supply and any portion of the cleaner may have its bulkiness substantially reduced merely by exerting a small tension thereon so that the reduced diameter portion may pass into a crevice between the points of contacts of the crowns of adjacent teeth.
- the cleaner returns to its normal bulky condition to substantially fill the crevice and enable the filaments of the yarn with their hardened covering to be pulled through the cavity to dislodge particles therein and also to rub against the tooth surfaces.
- An interdental tooth cleaner comprising a length of textured yarn formed of a plurality of filaments that have been individually permanently deformed and crinkled throughout the length of the cleaner and a covering of hardened material on the filaments to increase their stiffness and memory, said length normally being bulky by the filaments being maintained deformed and crinkled but becoming essentially straightened by an elongating force that decreases its bulkiness and in which said length returns to being bulky upon removal of the elongating force.
- the method of making a continuous length of interdental tooth cleaner comprising the steps of supplying a continuous length of textured yarn formed of a plurality of individually deformed and crinkled filaments, increasing the bulkiness of the yarn by somewhat disentangling the filaments and forming a hardened coating on the somewhat disentangled filaments.
- step of increasing the bulkiness includes the step of exerting a stretching force on the yarn and then decreasing the stretching force.
