Description

Technical Field

[0001] This utility model relates to dental floss, and more particularly to a flat multi-fiber dental floss and a dental cleaning device using the same. Background Technology

[0002] Dental floss is a common product used in daily oral care. Toothbrushes can only reach 70% of the surface of teeth, while dental floss makes up for the shortcomings of toothbrushes. Dental floss has the advantages of being more convenient, efficient, safe, and hygienic.

[0003] In dentistry, it's generally recognized that plaque left on teeth after brushing is a major cause of dental and gum problems. Flossing is an effective way to remove plaque. Without flossing, plaque remains on the teeth, providing a barrier for bacteria to continue metabolizing carbohydrates and releasing acids that attack tooth enamel. Plaque formation not only leads to tooth decay and gum disease but is also linked to other serious health issues.

[0004] Dental floss is a device used to remove plaque and debris that adheres to the area around teeth. Currently, the market offers round dental floss and flat, single-fiber floss. Round floss, due to its thinner diameter, cannot provide sufficient cleaning between teeth, has limited effectiveness in cleaning the area around teeth, and can easily damage specific areas of the teeth. Flat, single-fiber floss is primarily made of PTFE and PA materials. PTFE is controversial due to the potential presence of carcinogenic substances such as PFAS, and both of these materials are single-fiber floss with a very smooth surface, thus also not providing sufficient cleaning quality. Utility Model Content

[0005] The purpose of this invention is to provide a flat multi-fiber dental floss that can solve at least one of the aforementioned technical problems. The technical solution of this invention is as follows:

[0006] A flat, multi-fiber dental floss, comprising at least:

[0007] First thread body;

[0008] The second thread body; and

[0009] The third thread body;

[0010] The first, second, and third silk threads are flat structures that interweave with each other along the same plane.

[0011] Its beneficial effects are that, by having at least three fibers intertwine along the same plane to form a flat structure, this flat, multi-fiber dental floss has a larger overall surface area compared to traditional cylindrical floss. This results in a more surface-to-tooth contact, increasing the friction area and allowing for better cleaning of residue and plaque, thus better protecting the teeth. Furthermore, the increased contact area reduces localized pressure between the floss and the teeth, preventing tooth abrasion and further protecting them.

[0012] The specific weaving method involves each thread being folded sequentially from one side to the other, alternating between "passing through from the bottom" and "passing through from the top" when intersecting with adjacent threads. Each thread is then folded back in the opposite direction upon reaching the other side.

[0013] The flat, multi-fiber dental floss of this patent can be used as a component material specifically for making dental floss picks. Alternatively, it can be made into a roll and encased in a shell for direct use.

[0014] In some embodiments, the flat structure has undulating recesses and protrusions on its surface due to their interlacing.

[0015] Its beneficial effect is that, compared with traditional flat dental floss with a single fiber, this patent has undulating concave and convex sections, which can form a layer of interwoven fibers. This allows the dental floss to better clean and scrape away residues on the tooth surface when it rubs against the teeth through the concave and convex sections.

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

[0017] The beneficial effect is that using these materials can protect dental floss from wear and tear, ensuring it has good strength while also being soft enough to prevent tooth abrasion.

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

[0019] Its beneficial effect is that the lubricant can be a coated wax or an impregnated oil, to ensure that the floss and teeth are less worn.

[0020] In some embodiments, the first, second, and third filament bodies have the same diameter.

[0021] Its beneficial effect is that using the same diameter thread body can ensure a more neat weaving process, resulting in a more orderly and stable dental floss that is less prone to scattering.

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

[0023] Its beneficial effect is that it ensures 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 implementations, the thickness of the flat structure is less than or equal to twice the diameter of the filament body.

[0025] Its beneficial effect is that it ensures that the dental floss is thinner, thus presenting an overall flat shape, which is conducive to cleaning smaller spaces between teeth.

[0026] In some embodiments, it may also include at least two warp yarn bodies located in the same plane, with the first, second, and third yarn bodies interwoven together along the plane containing the warp yarn bodies to form a flat structure.

[0027] Its beneficial effect is that by setting the warp thread body, it can be ensured that the entire dental floss is interwoven along the warp.

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

[0029] Its beneficial effect is that, in addition to at least three silk threads intertwining with each other, multiple silk threads can be set up to intertwine with each other to form a flat structure.

[0030] The specific weaving method involves each thread being folded sequentially from one side to the other, alternating between "passing through from the bottom" and "passing through from the top" when intersecting with adjacent threads. Each thread is then folded back in the opposite direction upon reaching the other side.

[0031] This utility model also discloses a dental cleaning device, which includes a handle and a flat multifiber dental floss as described above disposed on the handle.

[0032] The beneficial effects are that 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 and better cleaning residue or plaque on the teeth, thus better protecting the teeth. Furthermore, because of the increased contact area, the local pressure between the floss and the teeth can be reduced, preventing tooth wear and further protecting the teeth. At the same time, because of the undulating concave and convex parts, a layer of interwoven fibers can be formed, allowing the floss to effectively clean and scrape away residue from the tooth surface during friction.

[0033] In addition, unless otherwise specified, all aspects of this utility model technical solution can be implemented by conventional means in the field. Attached Figure Description

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections, mechanical connections or electrical connections, direct connections or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] See Figures 1-2 As shown schematically, a flat multifiber dental floss according to the present invention comprises at least:

[0043] First thread body 1;

[0044] Second thread body 2; and

[0045] Third thread body 3;

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

[0047] This patented technique utilizes at least three filaments interwoven along the same plane to form a flat structure. This flat, multi-fiber dental floss has a larger overall surface area compared to traditional cylindrical floss, resulting in a more surface-to-surface contact with the tooth surface. This increased friction area allows for better cleaning of residue and plaque, thus better protecting the teeth. Furthermore, the increased contact area reduces localized pressure between the floss and teeth, preventing tooth abrasion and further enhancing dental health.

[0048] The specific weaving method involves each thread being folded sequentially from one side to the other, alternating between "passing through from the bottom" and "passing through from the top" when intersecting with adjacent threads. Each thread is then folded back in the opposite direction upon reaching the other side.

[0049] like Figure 3 As shown, the flat multifiber dental floss of this patent can be used as a component material specifically for making dental floss picks. Or as... Figure 4 As shown, dental floss can also be made into a roll and wrapped in a shell for direct use.

[0050] This patent features a flat structure with interwoven concave and convex portions 4 and 5 on its surface. Compared to traditional flat dental floss made of a single fiber, this patent, with its undulating concave and convex portions 4 and 5, allows for better cleaning and scraping away of residue from the tooth surface when the floss rubs against the teeth.

[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 mixture of nylon, polyester, polyethylene, and polypropylene.

[0052] Using these materials provides dental floss with good strength while maintaining sufficient softness to prevent tooth wear.

[0053] Meanwhile, the first filament body 1, the second filament body 2, and the third filament body 3 can all be coated or impregnated with lubricating substances.

[0054] The lubricant can be a coated wax or an impregnated oil to reduce wear between the dental floss and teeth.

[0055] The diameters of the first thread body 1, the second thread body 2, and the third thread body 3 are the same.

[0056] Using the same diameter thread body ensures a more uniform weaving process, resulting in a more neat and stable dental floss that is less prone to scattering.

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

[0058] This ensures that the dental floss width tends to be wider, resulting in an overall flat shape.

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

[0060] This ensures that the dental floss is thinner, resulting in a flat overall shape.

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

[0062] Its beneficial effect is that by setting the warp thread body, it can be ensured that the entire dental floss is interwoven along the warp.

[0063] Additionally, this patent may include any one or more of the following: a fourth filament body, a fifth filament body, a sixth filament body, a seventh filament body, an eighth filament body, a ninth filament body, a tenth filament body, an eleventh filament body, a twelfth filament body, a thirteenth filament body, and a fourteenth filament body.

[0064] In addition to at least three filament bodies intertwining with each other, multiple filament bodies can be set up to intertwine with each other to form a flat structure.

[0065] The specific weaving method involves each thread being folded sequentially from one side to the other, alternating between "passing through from the bottom" and "passing through from the top" when intersecting with adjacent threads. Each thread is then folded back in the opposite direction upon reaching the other side.

[0066] Of course, this patent only lists some examples of the number of threads. In addition to the embodiment with a total of 4-14 threads, it is actually only necessary to have more than 3 threads, or any number of 15-50 threads. This patent does not limit the specific number of threads to more than 3.

[0067] like Figure 2 As shown, a flat multifiber dental floss with 10 filaments is disclosed.

[0068] like Figure 3 As shown, this utility model also discloses a teeth cleaning device, which includes a handle 02 and a flat multifiber filament 01 disposed on the handle as described above.

[0069] The beneficial effects are that 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 and better cleaning residue or plaque on the teeth, thus better protecting the teeth. Furthermore, because of the increased contact area, the local pressure between the floss and the teeth can be reduced, preventing tooth wear and further protecting the teeth. At the same time, because of the undulating concave and convex parts, a layer of interwoven fibers can be formed, allowing the floss to effectively clean and scrape away residue from the tooth surface during friction.

[0070] In addition, unless otherwise specified, all aspects of this utility model technical solution can be implemented by conventional means in the field.

[0071] The above are merely some embodiments of this utility model, used only to illustrate the technical solution of this utility model, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above description without departing from the inventive concept of this utility model, and all such improvements and substitutions should fall within the protection scope of the appended claims of this utility model. In this case, all details can be replaced with equivalent elements, and the materials, shapes, and sizes can also be arbitrary.
