TEETH CLEANING DEVICE

The invention relates to a device for cleaning teeth, which device comprises a body, a space formed inside the body for dental floss and wire holders arranged at one end of the body, with wedge-shaped fixing grooves for fixing dental floss formed in the middle of the wire holder ends 5 and between the head and other wire holders.

The dental floss can be used to effectively clean the spaces between the teeth and thus prevent cavities. The most common use of dental floss is by hand, holding it with both hands, spraying the dental floss into the mouth between the teeth, and sweeping the gaps clean. This kind of wire use is cumbersome and unhygienic. There are various dental flosses that are used to aid in the use of dental floss. 15 GB application 2,074,876 discloses a tooth with a wire in which cross-shaped, wedge-shaped mounting grooves are formed in the ends of the wire holders. U.S. Patent 2,443,411 *: ·. the wedge-shaped grooves are also located at the ends of the wire holders, while in the device according to U.S. Patent 4,657,033, the wedge grooves are on the sides of the wire holders. Corresponding • · ”| the solution is also disclosed in U.S. Patent No. 2,784,722, ‘’ · in which ridges are formed in the grooves on the side.

In the device according to U.S. Pat. No. 3,871,393, the wedge-shaped grooves are located on the sides of the wire holders, but the device 25 has a special tightening mechanism. The problem with all the above-mentioned devices is that when using the devices, the dental floss can slide in its grooves, which makes the use of the device cumbersome and the wire has to be tightened constantly. In addition, the end of the wire is somewhat detached or easily detached, which also causes the wire to loosen.

The object of the invention is to provide a device for cleaning teeth, in which the dental floss is fixed 2 82806 tightly to the wire holders. In addition, the purpose of the invention! is to bring out a device that is simple in construction, inexpensive to manufacture, easy to use, hygienic and floss-saving.

The object of the invention is achieved by a device for cleaning teeth, which is characterized by what is stated in the claim.

The device according to the invention has a wire fastening groove. of

formed to prevent the wire from slipping in the fastening grooves

the ridges. In addition, protrusions are formed at the upper edge of the mounting groove in the center of the end of the second wire holder to prevent the end of the wire from coming off. In this case, the dental floss 15 wedges into the fastening grooves when it is wound on and around the end of the wire holders. The ridges in the grooves are arranged to prevent the dental floss from moving in the direction of the fastening groove. The shape of the ridges and their number vary in different embodiments of the invention. During cleaning, sheep ·. 20 The wire stays in place and cannot slip. Neither. the end of the wire cannot be detached from the attachment. Clean! After placement, the dental floss is removed by pulling it away from the mounting groove, allowing it to come off easily. * · In one embodiment of the invention, the ridges are shaped so as to prevent the dental floss from sliding only in the other direction. In such a device, the dental floss is always attached to the device in the same way.

The invention will now be explained in more detail with reference to '. 30 to the accompanying drawings, in which:. Fig. 1 shows an embodiment of a device according to the invention for cleaning teeth from the side, Fig. 2 shows another embodiment of the device according to the invention, seen from the side and in cross-section, Fig. 3 shows the fastening of a dental floss according to Fig. 2. 82806 Fig. 4 shows a cross-section of the first thread holder end of the device according to Fig. 3, Fig. 5 shows a top view of the end of the second thread holder of the device according to Fig. 3, Fig. 5 shows a section AA of Fig. 5, and Fig. 7 shows a section AA of Fig. 5. BB.

Figures 1 and 2 show two applications of the device according to the invention. The device according to Figure 1 is the so-called 10 The Y-shaped device and the wire holders are an extension of the frame. In the device according to Figure 2, the wire holders are arranged so as to extend transversely away from the body in relation to the body. Both devices include similar parts. The devices comprise a body 1, 15 in which a space 2 (not shown in Figure 1) is formed. A toothed wire spool 3 is placed in the space 2, which is placed in a holder 11 fixed to the lower part of the body.

• · · ·:. As shown in Fig. 2, from the space 2 inside the body, a channel 12 is arranged to extend through the body in the vicinity of the second wire holder 4. Thread exit hole * 25 13 and a guide groove ”· * · * 13 is formed between the end of the wire holder and is arranged to guide and hold the dental floss in place so that it does not slip to the side. In some applications, the channel is arranged to extend in the immediate vicinity of the end of the wire holder, so that a guide groove is not required.

»« * «· · * ·» »V Figures 3-7 show the structure i>» I ”of the ends of the wire holders and the fastening of the wire. At the ends of the wire holders there is a fastening groove 6 formed in the middle thereof, which divides the head into two substantially equal parts. Wire holder head · * “; and a second fastening groove 7 is formed between the rest of the part.

»· · 4 82806

The fastening grooves 6, 7 are mainly wedge-shaped in shape.

In addition, a ridge 8 is formed in the mounting grooves, which prevent the bag I u i u mn i s l a l <i ί n n i I y m ii i a:. , · Ι a: i on: i u n n I a i: i - :; I i. In the application shown here, the ridges are mainly triangular in cross-section, but their shape may vary in different applications.

Figures 5-7 show the structure of the wire holder to which the end of the dental floss is attached. Protrusions 9 are formed on the upper edge of the fastening groove 6a 10 to prevent the end of the wire from coming off. The structure of the second wire holder A is otherwise similar except that it has no protrusions.

When the device is not in use, the end of the dental floss is wrapped around the end of the 15 wire holder A. When using the appliance, remove the end of the thread from the holder and pull the thread outwards from the body. The wire is then fastened by twisting it around the ends of both angan holders 1 in the fastening grooves 6, 7. If necessary, the wire can be pulled more than 20 times between the wire holders, whereby the thickness of the wire can be effectively adjusted. However, due to the shape of the mounting grooves and the ridges, the wire stays firmly in place when the device is used. As shown in Figs. 3 and A, the wire is first drawn into the fixing groove 6 in the middle and then into the fixing groove 7 on the side, where the wire on the side tightens the wire between the wire holders tightly. After use, the wire is removed and cut with a cutting device 10 located in the center of the body. The cutting device is not close to the ends of the wire holders, so it does not damage the mouthpiece when using the device.

The invention is not limited to the preferred embodiments shown but may vary within the scope of the claims.
