Description

Technical Field

[0001] The present invention relates to dental floss, and more particularly to a flat multi-filament dental floss and a tooth cleaning device using the same. Background Art

[0002] Dental floss is a commonly used product in daily oral care. A toothbrush can only reach 70% of the tooth surface. Dental floss makes up for the deficiencies of a toothbrush and has the advantages of being more convenient, efficient, safe, and hygienic.

[0003] In the dental profession, it is generally recognized that dental plaque remaining on teeth after brushing is the main cause of tooth and gum problems. Using dental floss for treatment is an effective method for removing dental plaque. Without using dental floss, the dental plaque will remain on the teeth and provide a barrier for bacteria to continue metabolizing carbohydrates and excreting acids, thereby attacking tooth enamel. The formation of dental plaque not only causes tooth decay and gum disease but is also related to other serious health problems.

[0004] Dental floss is exactly a device for removing dental plaque and debris attached to the human teeth. Currently, there are round dental floss and flat single-filament dental floss on the market. Round dental floss has a relatively thin wire diameter and cannot provide sufficient cleaning quality between teeth, with limited cleaning effect on the teeth and is prone to damage to local positions of the teeth. Flat single-filament dental floss is mainly made of PTFE and PA materials. Among them, PTFE material is controversial because it may contain carcinogenic substances such as PFAS, and these two materials are single filaments with a very smooth surface, so they also cannot provide sufficient cleaning quality. Summary of the Invention

[0005] The object of the present invention is to propose a flat multi-filament dental floss, which can solve at least one of the above technical problems. The technical solution of the present invention is as follows:

[0006] A flat multi-filament dental floss, at least including:

[0007] A first thread body;

[0008] A second thread body; and

[0009] A third thread body;

[0010] The first thread body, the second thread body, and the third thread body are a flat structure that is intertwined with each other along the same plane.

[0011] Its beneficial effects are as follows: at least three silk thread bodies are intertwined with each other along the same plane to form a flat structure. Compared with the traditional cylindrical dental floss, the overall surface area of such a flat multi-fiber dental floss has a more surface-contact-like situation with the tooth surface, thus increasing the friction area, enabling better cleaning of the residues or dental plaque on the teeth, and better protecting the teeth. Moreover, due to the increased contact area, the local pressure between the dental floss and the teeth can be reduced, thereby preventing tooth wear and better protecting the teeth.

[0012] The specific intertwining method is that each silk thread body is folded from one side to the other in sequence, and when it comes into contact with the adjacent silk thread body, it alternates between "passing through from the bottom" and "passing through from the top". When each silk thread reaches the other side, it is then folded back in the reverse direction.

[0013] The flat multi-fiber dental floss of this patent can be used as a component material specifically for making dental floss holders. It can also be made into a rolled dental floss wrapped by a casing and used directly.

[0014] In some embodiments, the flat structure has undulating concave and convex portions formed due to the mutual intertwining on the surface.

[0015] Its beneficial effects are as follows: compared with the traditional flat dental floss made of a single fiber, since this patent has undulating concave and convex portions, it can form a fiber layer with high and low intertwining. Thus, when the dental floss rubs against the teeth, the residues on the tooth surface can be better cleaned and scraped away through the concave and convex portions.

[0016] In some embodiments, the materials of the first silk thread body, the second silk thread body, and the third silk thread body are any one or any mixture of nylon, polyester, polyethylene, and polypropylene.

[0017] Its beneficial effects are as follows: using these materials can ensure that the dental floss has good strength and corresponding softness, preventing tooth wear.

[0018] In some embodiments, the first silk thread body, the second silk thread body, and the third silk thread body are all coated or impregnated with a lubricating substance.

[0019] Its beneficial effects are as follows: the lubricating substance can be a wax coating or an infiltrated oil to ensure reduced wear between the dental floss and the teeth.

[0020] In some embodiments, the first silk thread body, the second silk thread body, and the third silk thread body have the same diameter.

[0021] Its beneficial effects are as follows: using silk thread bodies with the same diameter can ensure neater weaving during the knitting process, making the finally formed dental floss more regular and stable, and not prone to scattering.

[0022] In some embodiments, the width of the flat structure is greater than or equal to twice the diameter of the silk thread body.

[0023] The beneficial effect is that it can ensure that the width of the dental floss tends to be wider, thus presenting an overall flat shape and increasing the cleaning contact surface.

[0024] In some embodiments, the thickness of the flat structure is less than or equal to twice the diameter of the silk thread body.

[0025] The beneficial effect is that it can ensure that the thickness of the dental floss tends to be thinner, thus presenting an overall flat shape and being beneficial for cleaning smaller interdental spaces.

[0026] In some embodiments, it may further include at least two warp silk thread bodies. The warp silk thread bodies are located in the same plane, and the first silk thread body, the second silk thread body, and the third silk thread body are intertwined with each other along the plane where the warp silk thread bodies are located to form a flat structure.

[0027] The beneficial effect is that by setting the warp silk thread bodies, it can ensure that the entire dental floss is intertwined along the warp.

[0028] In some embodiments, it may further include any one or more of the fourth silk thread body, the fifth silk thread body, the sixth silk thread body, the seventh silk thread body, the eighth silk thread body, the ninth silk thread body, the tenth silk thread body, the eleventh silk thread body, the twelfth silk thread body, the thirteenth silk thread body, and the fourteenth silk thread body.

[0029] The beneficial effect is that in addition to the mutual interweaving of at least three silk thread bodies, multiple silk thread bodies can be further set to be intertwined with each other to form a flat structure.

[0030] The specific interweaving method is that each silk thread body is folded from one side to the other in sequence, and when passing through the adjacent silk thread body, it alternates between "passing through from the bottom" and "passing through from the top". When each silk thread reaches the other side, it is then folded back in the reverse direction.

[0031] The present invention also discloses a tooth cleaning device, which includes a handle and the above-mentioned flat multi-filament dental floss disposed on the handle.

[0032] Its beneficial effects are as follows. The tooth cleaning device of this patent has a contact with the tooth surface that is closer to surface contact, thereby increasing the friction area, enabling better cleaning of residues or dental plaque on the teeth, and thus better protecting the teeth. Moreover, due to the increased contact area, the local pressure between the dental floss and the teeth can be reduced, thereby preventing tooth wear and better protecting the teeth. At the same time, because of the undulating concave and convex parts, a fiber layer with interwoven highs and lows can be formed. Thus, when the dental floss rubs against the teeth, the residues on the tooth surface can be better cleaned and scraped off through the concave and convex parts.

[0033] In addition, in the technical solution of the present invention, unless otherwise specifically stated, this technical solution can be implemented by adopting conventional means in the art. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", "superior", "inferior", "main", "secondary", etc. are only used for descriptive purposes and can simply be used to more clearly distinguish different components, rather than indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, etc., it can be a mechanical connection, an electrical connection, it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0042] See Figures 1 - 2 As shown, schematically shown is a flat multi-filament dental floss according to the present invention, which at least includes:

[0043] A first silk thread body 1;

[0044] A second silk thread body 2; and

[0045] A third silk thread body 3;

[0046] The first silk thread body 1, the second silk thread body 2 and the third silk thread body 3 are flat structures that are intertwined with each other along the same plane.

[0047] In this patent, at least three silk thread bodies are intertwined with each other along the same plane to form a flat structure. The overall surface area of such a flat multi-filament dental floss is larger than that of a traditional cylinder, and its contact with the tooth surface is closer to surface contact, so that the friction area is increased, and the residues or dental plaque on the teeth can be better cleaned, thus better protecting the teeth. Moreover, because the contact area is increased, the local pressure between the dental floss and the teeth can be reduced, thereby preventing the teeth from being worn and better protecting the teeth.

[0048] The specific intertwining method is that each silk thread body is folded from one side to the other side in turn, and when it meets the adjacent silk thread body, it alternately passes through from the bottom and from the top. When each silk thread reaches the other side, it is then folded back in the reverse direction.

[0049] As Figure 3 shown, the flat multi-filament dental floss of this patent can be used as a component material specifically for making dental floss holders. Or as Figure 4 shown, it can also be made into a roll of dental floss wrapped in a casing for direct use.

[0050] In the flat structure of this patent, undulating concave portions 4 and convex portions 5 are formed due to the interweaving on the surface. Compared with the traditional flat dental floss made of a single filament, because of the undulating concave portions 4 and convex portions 5 in this patent, when the dental floss rubs against the teeth, the residues on the tooth surface can be better cleaned and scraped off through the concave portions 4 and convex portions 5.

[0051] The materials of the first filament body 1, the second filament body 2, and the third filament body 3 of this patent can be any one or any combination of nylon, polyester, polyethylene, and polypropylene.

[0052] Using these materials can protect the dental floss to have good strength, and at the same time have corresponding softness to prevent the teeth from being worn.

[0053] At the same time, the first filament body 1, the second filament body 2, and the third filament body 3 can all be coated or impregnated with a lubricating substance.

[0054] The lubricating substance can be the wax applied or the oil impregnated to ensure less wear between the dental floss and the teeth.

[0055] The first filament body 1, the second filament body 2, and the third filament body 3 have the same diameter.

[0056] Using filament bodies with the same diameter can ensure neater weaving during knitting, so that the finally formed dental floss is more regular and stable and not easy to scatter.

[0057] Preferably, the width of the flat structure is greater than or equal to twice the diameter of the filament body.

[0058] Thus, it can ensure that the width of the dental floss tends to be wider, so that the overall shape presents a flat shape.

[0059] At the same time, the thickness of the flat structure is less than or equal to twice the diameter of the filament body.

[0060] Thus, it can ensure that the thickness of the dental floss tends to be thinner, so that the overall shape presents a flat shape.

[0061] This patent also discloses that an embodiment may further include at least two warp silk thread bodies which are located in the same plane. The first silk thread body 1, the second silk thread body 2, and the third silk thread body 3 are intertwined with each other along the plane where the warp silk thread bodies are located to form a flat structure.

[0062] Its beneficial effect is that by setting the warp silk thread bodies, it can ensure that the entire dental floss is intertwined along the warp.

[0063] Meanwhile, this patent may further include any one or more of the fourth silk thread body, the fifth silk thread body, the sixth silk thread body, the seventh silk thread body, the eighth silk thread body, the ninth silk thread body, the tenth silk thread body, the eleventh silk thread body, the twelfth silk thread body, the thirteenth silk thread body, and the fourteenth silk thread body.

[0064] In addition to the mutual interweaving of at least three silk thread bodies, multiple additional silk thread bodies can be provided for mutual interweaving to form a flat structure.

[0065] The specific interweaving method is that each silk thread body is folded from one side to the other in sequence, and when passing adjacent silk thread bodies, it alternates between "passing through from the bottom" and "passing through from the top". When each silk thread reaches the other side, it is then folded back in the reverse direction.

[0066] Of course, only some quantities of silk thread bodies are listed in this patent. Except for the embodiments with 4 - 14 silk thread bodies in total, actually only more than 3 are required, and it can also be any one of 15 - 50. In this patent, the specific number greater than 3 is not limited.

[0067] As Figure 2 shown, a flat multi - fiber dental floss with 10 silk thread bodies is disclosed.

[0068] As Figure 3 shown, the present invention also discloses a tooth cleaning device which includes a handle 02 and the above - mentioned flat multi - fiber dental floss 01 provided on the handle.

[0069] Its beneficial effects are as follows: The tooth cleaning device of this patent has a contact with the tooth surface that is closer to surface contact, thereby increasing the friction area, enabling better cleaning of the residues or dental plaque on the teeth, and thus better protecting the teeth. Moreover, because the contact area is increased, the local pressure between the dental floss and the teeth can be reduced, thereby preventing tooth wear and better protecting the teeth. At the same time, due to the presence of the undulating concave and convex parts, a fiber layer with high - low interweaving can be formed, so that when the dental floss rubs against the teeth, the residues on the tooth surface can be better cleaned and scraped off through the concave and convex parts.

[0070] In addition, in the technical solution of the present invention, unless otherwise specified, the present technical solution can be implemented by adopting conventional means in the art.

[0071] The above are only some embodiments of the present invention, which are only used to illustrate the technical solution of the present invention and are not intended to limit it. It should be understood that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, improvements or substitutions can be made according to the above description, and all such improvements and substitutions should fall within the protection scope of the appended claims of the present invention. In this case, all details can be replaced by equivalent elements, and the materials, shapes and dimensions can also be arbitrary.
