JP7038982B2 - The floss fixing method in the floss for cleaning the teeth and the product thereof. - Google Patents

Description

The present invention relates to a method for fixing floss in an interdental cleaning floss and a product thereof.

Triangular toothpicks and interdental brushes are used to clean the interdental area, but in the upper part of the interdental area, a special floss is used because the interdental space is extremely small.
This floss is a chemical yarn such as polyester, and has a structure in which hundreds of ultrafine yarns are bundled and flattened by reducing the amount of twisting, and easily inserted between teeth.
In addition, there is also a floss in which the above-mentioned floss is harder and flattened than a substance intended for lubrication.

In Japan, the above-mentioned floss is mainly a disposable product that is cut to about 3 to 5 cm and is simultaneously molded with a tension on the bow-shaped part of a resin molding member that is bow-shaped and has a handle on one end. The products that are used habitually in European countries and the United States of America are products that are simply wound and packaged with floss of about 20 to 30 m, and the mainstream method is to take out and cut the amount to be used and clean the teeth. Then, the patent documents relating to the above-mentioned products are described below.

The problem that the inventor tries to solve

As described in Japanese Patent Application No. 2016-113918 filed for patent on May 20, 2016 by the present inventor, in disposable products that are mainstream in Japan, the tension of floss is like a product that uses a finger. It cannot be adjusted, and problems may occur depending on the shape between the teeth. In addition, a bow-shaped molded product is required, and a large amount of molded product is required for the manufacturer, and even if it seems cheap to the user, it is more expensive than the products used in European countries and the United States. .. In addition, since it is a disposable product, it can be said to be hygienic, but it cannot be said to be an eco-friendly product that is trending with the times.

Even for products that are used habitually in European countries and the United States, the amount of floss used for one interdental cleaning is required to be 30 to 40 cm in order to use both hands, and it is necessary to be proficient in using both hands, Japan. As a human culture, it is necessary to dispel the discomfort of inserting a finger into the oral cavity.
Since tooth cleaning is as important as tooth surface cleaning (brushing), it is necessary to continue habituation, and it is important that floss products are economical, inexpensive, easy and accurate. This was the subject of product development.

Means to solve problems

From a hygienic point of view, the floss has a size that is easy to hold even in the size of a woman's palm, and has a structure that allows the floss to be completely fixed each time the amount used is withdrawn. Next, wrap it around the middle finger of one hand at intervals of about 10 cm, hold it at a distance of 2 to 3 cm with the thumb and index finger of one hand, stretch the floss tightly, and insert it along the surface of the teeth while gently moving back and forth, slowly moving up and down. The structure is such that stains (colored stains) and plaque are removed by moving and brushing the surfaces of adjacent teeth.

We have also developed a nunchaku-type product in which floss protrudes from the tip of a stick for the purpose of easily and accurately cleaning the interdental space of the back teeth (molars) for those who feel uncomfortable with the act of inserting a finger into the oral cavity. did. Similar to the above-mentioned products, this product also has a structure in which the floss is wound up and located inside the case so that it can be fixed and pulled out.

The invention's effect

The floss is housed in a palm-sized case, and the structure allows the floss to be easily fixed, making it possible to clean the teeth by simply wrapping it around the middle finger or index finger of one hand. In addition, the amount of floss used at one time can be reduced from 30 to 40 cm to about half.

From a hygienic point of view, it is possible to clean the teeth by simply pulling out the floss from the case and wrapping it around the middle finger or index finger of one hand. In addition, since the tension of the floss can be adjusted by the shape between the teeth, troubles during use are reduced.

In the nunchaku type, which uses two rods, the interdental cleaning of the back teeth (molars) can be easily performed, and it is no longer necessary to insert a finger into the oral cavity.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

The floss fixing method shown in FIG. 1 is as follows. The interdental cleaning floss 1A is set in advance on the case shaft 2B of the case 2 as a floss winding 1 for interdental cleaning of about 20 to 30 m so as to be freely rotatable. The interdental cleaning floss 1A drawn out from the interdental floss winding 1 passes through a small hole located in the center of the case floss guide portion 2D, passes through the central portion of the case floss fixing portion 2C, and is pulled out from the floss protruding small hole 2G. Is done. As shown in FIG. 1, the case hinge 2E located in the center of the case opens and closes the case, and the case opening / closing portion 2F fixes the case bottom 2A. Further, FIG. 2 is a cross section of AA and BB of the case floss fixing portions 2C provided on the case upper 2 and the case lower 2A, and shows a structure for fixing the interdental floss 1A passing near the center of the upper and lower unevenness. It is a thing.

In the method of fixing the floss shown in FIG. 1, the used floss 1A for cleaning the teeth after cleaning the teeth is cut off by a cutter provided on the case, and the case opening / closing portion 2F is opened a small amount to provide an appropriate amount of the floss 1A for cleaning the teeth. You can pull it out one by one.

In the floss fixing method of FIG. 3, the tooth-tooth cleaning floss 1A drawn out from the tooth-tooth cleaning floss roll 1 freely rotatably attached by the case shaft 2B provided in the case is previously formed in the case by simultaneous molding. Case rotating frame outside the case 3 circumferences outside the provided case Rotating handle small holes (grooves) 3A located at two locations outside the rotating frame Passing through one side and freely built-in rotating handle 4 Circumferential side surfaces After passing through one of the holes (grooves) 4A and protruding from the other, and passing through the other small hole (groove) 3A outside the rotating frame of the case, it is pulled out from the floss protruding small hole 2G provided at the tip of the case and used for interdental cleaning.

FIG. 4 is an enlarged view of a method for fixing the interdental cleaning floss 1A in this product. The case rotating frame outer small hole (groove) 3A, the rotating handle small hole (groove) 4A (two places), the case rotating frame outer small hole (groove) 3A, and the tooth gap cleaning floss 1A that passed through the other were provided on the rotating handle 4. By rotating the rotary handle handle 5, it is wound around the circumferential side surface of the rotary handle 4 to change the direction, and is fixed by utilizing the narrow space between the inner surface of the case rotating frame 3 and the outer peripheral surface of the rotary handle 4. To.

Further, by rotating the rotary handle 4 in the direction of the arrows shown in FIGS. 3 and 4 to make each small hole (groove) linear, the interdental cleaning floss 1A can be easily pulled out. The force for fixing the floss can also be selected by selecting the rotation handle 4 from 90 degrees (1/4 rotation) to 360 degrees (one rotation).

The floss fixing method of FIG. 5 uses the square shaft 6 shown in FIG. FIG. 7 is an enlarged view of the cross-sectional shape CC of this shaft. A square shaft bobbin portion 6A is provided near the central portion of the square shaft 6, and only the shaft shape of the bobbin portion is a round shaft for winding the interdental cleaning floss 1A. There is also a method of inserting the floss roll 1 for cleaning the interdental teeth from which the floss has been wound in advance.

The interdental cleaning floss 1A is set in the take-up case on the square shaft bobbin portion 6A located near the central portion of the square shaft 6 described above. The interdental cleaning floss 1A drawn out from the square shaft bobbin portion 6A set in the through small hole in the case with a margin is used by being drawn out from the floss protruding small hole 2G through the floss guide portion 2D of the case.

The method of fixing the interdental cleaning floss 1A in this product is to simply lower the square shaft 6 in the direction of the arrow (downward) shown in FIG. 5 and drop it into the square groove portion 2H of the case. This time, we inquired about the square shaft shape, but it can be said that a more suitable shaft shape is a polygonal shape. The reason is that the act of fixing and releasing proceeds smoothly by advancing the polygonal shape, and the same applies to the drawer of the interdental cleaning floss 1A.

In the above method, the interdental cleaning is performed by wrapping the interdental cleaning around one finger, and FIG. 8 shows an inquiry of the method of performing the interdental cleaning accurately and without using a finger.

The interdental cleaning floss 1A pulled out from the interdental cleaning floss roll 1 freely rotatably fixed to the inner case shaft 2B of the case 2 protrudes from the case floss fixing small hole 2I located near the center of the case insertion convex portion and is hollow. A hollow rod floss fixing small hole 7B that passes through the rod 7 and enters the other hollow rod tip small hole 7A from the hollow rod tip small hole 7A and passes through the hollow rod 7 and protrudes from the fixing cap small hole 8A provided in the floss fixing cap 8. Pass through and go out to the outside.

In the method of fixing the interdental cleaning floss 1A by this method, the interdental cleaning floss 1A is fixed by inserting the tip of the case 2 into the hollow rod 7. It can be said that the method of rotation is also preferable in the sense that the fixing is more complete. FIG. 9 is an enlarged version of the details of using the floss fixing cap 8 as another method. The floss fixing cap 8 is rotated in the direction of the arrow, and the positions of the hollow rod floss fixing small hole 7B and the floss fixing cap small hole 8A are shown. Is fixed by slurping. This method uses the method of FIG. 3 described above in the rod-shaped type, and in FIG. 8, the fixing method is different between the case 2 side and the floss fixing cap 8 side, but the same method can also be used. ..
