Abstract

PROBLEM TO BE SOLVED: To consider a method for solving problems in which it is impossible to make fine adjustment of the straining of a floss thread for interdental cleaning because an arched product becoming a main stream in Japan is a disposable product in retrograde to the times, and also in a method being widely used in each European country and in the United States for many years, the method that winds a thread several times in the vicinity of the first joints of middle fingers of both hands, and pinches it with an index finger and a thumb, many steps to usage are present and complex, and skill becomes indispensable, in addition, the Japanese have habitual resistance against putting fingers in the oral cavity and have problems in the oral shape, and therefore the spread proceeds only slowly.SOLUTION: A floss thread supply device is invented by the present inventor, the device being simple in operation procedures of a floss thread for interdental cleaning and facilitates replacement, can finely adjust the straining of the floss thread for interdental cleaning being an important factor when in use, and can fix the end completely. This floss thread supply device is attached to an exclusive interdental cleaning tool of each shape, and whereby the fine adjustment of replacement, fixation and straining of the floss thread for interdental cleaning is simplified easily.SELECTED DRAWING: Figure 1

Description

The present invention relates to a floss yarn supply device and its structure.

The tools used in the oral cavity vary depending on each part, and a toothbrush is used to clean the tooth surface, and a triangular toothpick and interdental brush are used to clean the lower interdental area (an isosceles triangle consisting of interdental and gingival). It is preferable to use an interdental cleaning floss thread for the upper part of the interdental area and a soft rubber cleaning tool dedicated to the tongue for the tongue surface. In addition, products that use specially processed melamine foam are also available for removing colored stains derived from living organisms such as coffee, tea, and tobacco.

In addition, since the lifespan of human beings has become long-lasting, the Dental Society has recently promoted the 8020 movement (leaving more than 20 teeth at the age of 80), which is important not only for therapeutic medicine but also for preventive medicine. It shows. The core act of preventive medicine is oral care performed by each person, and it is important to continue the act and there is a need to be able to carry it out easily and conveniently. The present invention described below is important from the viewpoint of preventing dental caries in the oral cavity cleaning, and a document on an upper interdental cleaning tool that uses a floss thread for interdental cleaning, which is less implemented than European countries and the United States. It is.

Problems to be solved by the inventor

The only method for cleaning the upper part of the interdental area is the use of a floss thread, which is implemented by the following method in European countries and the United States. The procedure consists of pulling out the floss thread for interdental cleaning from the case, cutting it to about 40 cm, winding it around the first joint of the middle finger of both hands up to a distance of about 15 cm, and 1-2 cm with both thumbs and forefinger. Tighten the floss thread for interdental cleaning and pinching with a pin, and insert it along the tooth surface while gently moving back and forth, and gently move it up and down to polish the adjacent tooth surface The process is completed by six steps, a step of removing stains (colored stains) and plaque, and a step of removing from both fingers after use and discarding.

In Japan, instead of the above method, the interdental cleaning floss thread cut to about 3 to 5 cm is bow-shaped, and the bow-shaped portion of the resin molded member with a handle at one end is simultaneously tensioned. Molded disposable products have become mainstream, and a small number of products that replace floss yarn for interdental cleaning are also available on the market.

However, there is a problem to be solved for each of the above-described products. In the method of wrapping the interdental cleaning floss thread around the middle finger of both hands, it has been widely used for many years in Europe and the United States, and it is easy to fine-tune the tension of the interdental cleaning floss thread. On the other hand, the number of processes required for use is large and time-consuming, and skill is indispensable. In addition, Japanese people have not been popularized because they are culturally resistant to putting their fingers in the mouth and their mouth shapes are slightly different from those in European countries and the United States.

The bow-shaped products that are the mainstream in Japan are disposable products that run backwards in the times, and it is uneconomical when considered from the viewpoint of being used for many years at a pace several times daily. Further, it is impossible to finely adjust the tension of the floss thread for interdental cleaning, and forcibly inserting it into the interproximal part may lead to breakage or accidentally damage the lower gingiva. Even in products that replace the floss thread for interdental cleaning, the thread is not sufficiently fixed. Not economical. The exchange method has problems such as complexity and has not been widely spread.

The present inventor has a simple and easy replacement procedure for the floss thread for interdental cleaning, can finely adjust the tension of the floss thread for interdental cleaning, which is an important factor during use, and can completely fix the end. The problem was a floss yarn feeder.

Means for solving the problem

A floss thread for interdental cleaning wound on a single bobbin or a connecting bobbin is set in the case, and each bobbin small hole and upper and lower case small holes are freely held by the through shaft and are attached to one end of the through shaft. The interstitial cleaning floss yarn is mechanically fixed by connecting the gears provided circumferentially on one side of each bobbin and the inside surface of the case by the inserted spring. Also, when releasing and pulling out the floss thread for interdental cleaning, it can be completed simply by pressing the cap fitted into the through shaft, and the end pulled out can be wound on or picked from the finger, and the finger can be removed by simply removing the finger from the cap. Cleaning can be started.

Also, by using a connecting bobbin and setting the winding direction of the floss thread for interdental cleaning in the reverse direction, it is equivalent to the amount pulled out (the remaining amount of floss thread for interdental cleaning even if the bobbin shaft diameter is the same size) Can be automatically stored in another bobbin). By using this mechanism, the new interdental cleaning floss thread is pulled out and the used interdental cleaning floss thread is stored.

Effect of the invention

The floss yarn for interdental cleaning, which has been widely used in European countries and the United States for many years, has made it easier to fine-tune the tension regardless of skill. In addition, continuity has also increased due to the convenience of multiple steps such as wrapping around both hands and the middle joint of the middle finger before use.

In addition, the connection bobbin structure eliminates the need to cut and discard the floss yarn for interdental cleaning after use.

Considering from the viewpoint of hygiene, it can be said that it is significant from the decrease in the number of times the floss yarn for interdental cleaning is touched. In addition, since it is not necessary to manufacture the handle portion and it is not necessary to wrap it around the middle finger of both hands, it can be said that the amount of use at one time is halved and it is economical.

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

The inter-dental cleaning floss thread 1 is wound about 30 m (equivalent to a commercially available inter-dental cleaning floss thread product) on a single bobbin 2 at one winding position, and is wound several times around the first joint of the index finger 3 FIG. 1 is an oblique view showing a pulled-out state, and a bobbin small hole 4 </ b> B is provided at the center of the single bobbin 2.

FIG. 2 is a view in which the single bobbin 2 is assembled in the case 5 and cut along the AA section, and the detailed description is as follows.

The remaining side of the spring 6, the single bobbin 2, and the case 5 are stacked on the case small hole 4B provided in the case 5 having a left and right split structure, and the through shaft 4 is inserted into each small hole, The case gear 7 and the bobbin gear 8 shown in FIGS. 5 and 6 were provided in a circular shape inside the one-side plane of the single bobbin 2 and the case 5 one-side plane.

If the above-described structure is used, the single bobbin 2 is brought into a free state simply by pressing the cap 4A placed on the through shaft 4, and the flat surface is pressed against the spring 6 so that the floss thread 1 for interdental cleaning is fixed with a certain tension. The single bobbin 2 is pressed against the inside of one side of the case 5 by the repulsive force of the spring 6 at the same time as the finger is released from the cap 4A, so that the case gear 7 and the bobbin gear 8 are connected to each other, and the interdental cleaning floss is connected. It is possible to mechanically completely fix the yarn 1.

Next, a method of attaching the interdental cleaning floss thread 1 in the connecting bobbin 2A shown in FIG.

The floss thread 1 for interdental cleaning is wound around one middle of the connecting bobbin 2A at two winding positions by either the left or right rotation direction. Each floss yarn for cleaning is explained by each manufacturer. Taking it up to a small amount of about 150 mm and taking into consideration the palm size of the user's palm), the end face is attached to the other side of the connecting bobbin 2A in the reverse rotation direction and fixed. As shown in FIG. 3, the circumferential inter-tooth cleaning floss thread 1 protruding from the connecting bobbin 2A is automatically stored in the other connecting bobbin 2A when the connecting bobbin 2A rotates in the direction of the arrow. Is done. In this case as well, the basic structure is the same as that of the single bobbin 2 described above, and has a small bobbin hole 4B in the center.

FIG. 4 is a view in which the connecting bobbin 2A is assembled in the case 5 and cut with a BB cross section. The outline of the structure is the same as that of the single bobbin 2 described above, and the difference is in the shape of the bobbin and the spring 6. Instead, a leaf spring 9 that can be molded simultaneously with the case is used, and an example in which the number of parts is reduced is shown.

In the case of this connection bobbin 2A structure, the pull-out amount and the storage amount of the floss thread 1 for interdental cleaning differ little by little even if the shaft diameter of the connection bobbin 2A is the same 50 mm, and the diameter of the pull-out bobbin is about 52. 6 mm (when the bobbin width is 9 mm), the amount of the floss yarn 1 for interdental cleaning in one rotation is about 165 mm, and the storage amount is about 157 mm, which is about 8 mm longer for each rotation. However, the difference between the output amount and the storage amount decreases with use, and increases up to about 270 mm at the intermediate point (7.5 m). The storage amount gradually increases with respect to the output amount, and the floss yarn for interdental cleaning If there is no physical property change such as expansion and contraction in 1 and winding is average and accurate at the same time, the length is finally equal to that at the start of use.

If the protruding amount from the connecting bobbin 2A in the interdental cleaning floss thread 1 shown in FIG. 3 is about 330 mm (for two rotations), both ends are fixed, and therefore, as shown in FIG. It is only necessary to wrap it for one week or to pick it with the index finger 3 and the thumb, and the used portion 150 mm can be secured twice. Even with a winding amount of 15 m, the interdental cleaning floss thread 1 can be replaced 90 times. By the way, it is wrapped around the first joint of the middle finger of both hands on the market, and is picked with the index finger 3 and thumb. Since there are many products, the number of uses is 75 times.

Further, the total length at the intermediate point (about 7.5 m position) where the amount of the floss thread 1 for interdental cleaning to the outside of the connecting bobbin 2A is the largest (long) is 330 mm, which is an increase of 270 mm. This is 600 mm plus, which can be said to be MAX (longest dimension).

Even in this MAX (longest dimension) state, the interdental cleaning floss yarn 1 is in a circumferential state (annular shape) and is 191 mm in terms of diameter, and the experiment was repeated using model products by several monitors. There was no problem.

Next, the structures of the case gear 7 and the bobbin gear 8 that are indispensable for the fixing method of the floss thread 1 for interdental cleaning were inquired as enlarged views in FIGS. 5 and 6. In FIG. 5, the gear is mechanically fixed in the arrow C direction (left and right) by receiving a force from the upper arrow direction and coupling. According to this coupling method, even if it is used repeatedly, there is no change in fixation and it does not loosen. Since the shape of this gear can correspond to both the left and right directions, it is used when the coupling bobbin 2A shown in FIGS. 3 and 4 is used.

When the gear shown in FIG. 6 is used, it can be said that it is preferable when the single bobbin 2 is used in FIGS. As can be understood from the gear shape, it can be said that the inter-tooth cleaning floss yarn 1 can be mechanically fixed in the D direction as in the gear described above, but fixed in the reverse direction E. I can't do it. Therefore, it is fixed in one direction. In this case, with respect to the E direction, an accurate inter-tooth cleaning floss yarn is drawn out for each inclined surface dimension of one gear, and a “drawer” is provided each time with a tension. In addition, if the inclined shape (isosceles triangle shape) is used in both the left and right directions, the drawer can be accurately and tensioned as described above in both the left and right directions.

This gear is provided on the case piece plane and the bobbin piece plane by simultaneous molding, thereby reducing the number of parts. It is also effective to fix the shape of the floss yarn 1 for interdental cleaning with wax (harmless ingredients) for the purpose of suppressing the coefficient of friction so that it can move smoothly through the flossing device and to facilitate interdental insertion. It is. At this time, a method of blending calcium, which is effective in preventing dental caries and effective in removing plaque, and fluorine, and used interdental cleaning floss yarn 1 in the wax are stored in adjacent bobbins. Therefore, it has been considered to add a fragrance and an antibacterial agent.

In addition, even if the floss yarn after interdental cleaning is wound on an adjacent bobbin (another separate bobbin), it is unsanitary and has excellent antibacterial properties against voices that are concerned about odors. It can also be considered to use a resin impregnated with silver which is recognized as being. Moreover, the wall (ear) on both sides of each bobbin is preferably 5 mm or more from the purpose of accurately winding the floss thread 1 for interdental cleaning and the above-mentioned hygiene, and one of the above methods is used. Just doing it will have an effect.

The case gear and the bobbin gear described above are also provided circumferentially with respect to each plane, the height is preferably about 1 to 2 mm, and the width is preferably about the same. Moreover, this floss device can be used for interdental cleaning tools having various shapes including an interdental cleaning tool having a rod-shaped handle. FIGS. 7 and 8 are image diagrams showing an example of a method for cleaning the teeth 10 by inserting a floss device into the case 5 having a doorway at one end.
