Description

Technical Field

[0001] This application relates to the field of oral hygiene products technology, and in particular to a dental floss and dental floss picks. Background Technology

[0002] With the development of the times and the gradual improvement of living standards, people are paying more and more attention to oral hygiene, and there are more and more tools for oral cleaning, such as dental floss picks. People can use the floss on dental floss picks to scrape off the deposits on the tooth surface, and they can also use dental floss to remove deposits in areas such as between teeth and under the gums. Dental floss can remove food debris, tartar, and plaque that are difficult to remove by rinsing and brushing, which helps prevent oral diseases such as bad breath, tooth decay, and periodontal disease.

[0003] However, in related technologies, the friction generated when dental floss rubs against teeth is usually small, resulting in poor cleaning effect of dental floss on stubborn deposits such as plaque. Utility Model Content

[0004] This application provides a dental floss and a dental floss pick, which can improve the cleaning power of the dental floss, thereby improving the cleaning effect on stubborn deposits such as dental plaque.

[0005] In a first aspect, this application provides a dental floss comprising a base and a plurality of dental cleaning particles, wherein at least a portion of the dental cleaning particles are located within the base, and at least a portion of the dental cleaning particles are flush with or protrude from the surface of the base.

[0006] In some embodiments of this application, the surface roughness of the dental cleaning particles is greater than that of the polyester rubber matrix. By combining the matrix with the dental cleaning particles, the friction generated when the dental cleaning particles rub against the teeth is greater than that generated by the matrix, which can effectively clean stubborn deposits such as dental plaque, effectively prevent oral problems such as gingivitis and periodontitis, and promote oral health.

[0007] In some embodiments of this application, the matrix is ​​a polyester rubber matrix. On one hand, the polyester rubber matrix is ​​safe and non-toxic, has a smooth surface, good resilience, is not prone to fuzzing, and is not prone to fraying. This results in less friction between the matrix and teeth, and reduces the likelihood of fraying, splitting, and scattering. Consequently, the dental floss causes less damage to teeth and less irritation to gum tissue. It also has sufficient tensile strength for smooth back-and-forth movement, preventing it from getting stuck between teeth and improving user comfort. On the other hand, the polyester rubber matrix has sufficient strength, giving the dental floss adequate durability, toughness, and lifespan, allowing for the cleaning of the entire mouth with a single floss. Furthermore, polyester rubber combines the excellent elasticity of rubber with the processability of thermoplastics, resulting in good processing performance, easily controllable processing conditions, and high cost-effectiveness. This makes dental floss easier to mass-produce and offers excellent value for money.

[0008] In some embodiments of this application, the matrix and the dental floss particles are mixed and integrally molded. This results in a stronger connection between the matrix and the dental floss particles, and makes floss formation easier.

[0009] In some embodiments of this application, the width of the substrate is d, and the thickness of the substrate is h, where h < d, so that the substrate is flattened. This makes the dental floss as a whole flattened, which better matches the shape of the slit-like gaps between teeth, and makes it easier to insert into and slide back and forth within the gaps.

[0010] In some embodiments of this application, 0.2 mm ≤ d ≤ 5 mm; and / or, 0.02 mm ≤ h ≤ 0.2 mm. This ensures efficient flossing while preventing the base from being too wide, which could hinder floss insertion between teeth; and / or preventing floss from being too thin, which could easily damage the gums when in contact with them, while also preventing the base from being too thick, which could make floss difficult to insert between teeth.

[0011] In some embodiments of this application, the matrix is ​​a white translucent matrix or a transparent matrix; and / or, the flossing particles are colored particles. When the matrix is ​​white translucent or transparent, users can see the flossing particles within it, providing a more intuitive understanding of the improved cleaning power of the floss. It also enhances the aesthetics and enjoyment of flossing, making it more suitable for children. Furthermore, quality control personnel can more easily observe the distribution of the flossing particles during production, facilitating quality inspection and preventing consumers from receiving substandard floss. When dental floss granules are colored, their visibility is enhanced, allowing users to clearly see the distribution of the granules within the floss matrix. The colored granules also offer greater aesthetic appeal and fun, making them more suitable for children. Furthermore, the color of the granules can differentiate between different types of dental floss, making it easier for users to choose the appropriate type. For example, green granules are for freshening breath, purple granules are for preventing cavities, red granules are strawberry-scented, and green granules are watermelon-scented.

[0012] In some embodiments of this application, the dental cleaning particles are spherical, near-spherical, or ellipsoidal. Spherical dental cleaning particles can contact the tooth surface in a point-contact manner, resulting in a high concentration of contact stress on the teeth, which can further improve the cleaning effect of the dental cleaning particles and more easily and efficiently remove stubborn plaque. Near-spherical dental cleaning particles can contact the tooth surface in a multi-point-contact manner, increasing the probability of contact between the dental cleaning particles and the tooth surface, resulting in greater wear on the teeth, but with stronger cleaning power. Elliptical dental cleaning particles have a larger contact area with the tooth surface, resulting in relatively dispersed contact stress on the teeth, less wear on the teeth, and less discomfort when rubbing against the teeth, thus allowing the cleaning particles to simultaneously achieve both cleaning power and cleaning comfort.

[0013] In some embodiments of this application, the particle size of the dental cleaning particles is r, where 1 micrometer ≤ r ≤ 50 micrometers. This prevents the dental cleaning particles from being too small, which would make it difficult for them to significantly enhance friction and cleaning power, while also preventing the dental cleaning particles from being too large, which would cause greater pressure and irritation to the gaps between teeth and the gums.

[0014] In some embodiments of this application, the relative dentin abrasion value n of the teeth-cleaning particles is 40≤n≤240. This allows the teeth-cleaning particles to significantly enhance friction and cleaning power while reducing damage and discomfort to the teeth.

[0015] In some embodiments of this application, the ratio of the total volume of all the dental cleaning particles to the volume of the matrix is ​​m, where 3% ≤ m ≤ 30%. This allows the dental cleaning particles to significantly enhance friction and cleaning power, while preventing excessive wear on tooth enamel and irritation to the gums, and also preventing excessive addition of dental cleaning particles from reducing the toughness of the dental floss.

[0016] Secondly, this application also provides a dental floss pick, which includes a handle and dental floss as described in any of the above embodiments. The handle includes a stem portion and a mounting portion connected to the stem portion, and the dental floss is mounted on the mounting portion.

[0017] The beneficial effects of this application are as follows: By combining the matrix with dental cleaning particles, on the one hand, by placing at least some of the dental cleaning particles in the matrix, the overall density of the dental floss can be increased by utilizing the solid dental cleaning particles within the matrix, thereby improving the structural strength of the dental floss, enhancing its toughness and service life, and enabling the use of a single dental floss to clean all the teeth in the mouth; on the other hand, the dental cleaning particles, which are flush with or protrude from the surface of the matrix, can form uneven structures or areas of varying hardness on the surface of the matrix, allowing the dental cleaning particles to contact the teeth when using dental floss to clean them, increasing the frictional force generated when the dental floss rubs against the teeth, thereby effectively cleaning stubborn deposits such as plaque, and thus effectively preventing oral problems such as gingivitis and periodontitis, which is beneficial to oral health.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Based on the above-mentioned technical problems, this application provides dental floss and dental floss picks to solve the problem that in related technologies, the friction generated when dental floss rubs against teeth is usually small, resulting in poor cleaning effect of dental floss on stubborn deposits such as plaque.

[0023] Firstly, this application provides a dental floss 10, such as Figure 1 As shown, the dental floss 10 includes a base 11 and a plurality of dental floss particles 12, at least some of the dental floss particles 12 are located within the base 11, and at least some of the dental floss particles 12 are flush with or protrude from the surface of the base 11.

[0024] Understandably, by combining the base 11 with the floss particles 12, on the one hand, by placing at least some of the floss particles 12 within the base 11, the overall density of the dental floss 10 can be increased within the base 11 using solid floss particles 12, thereby enhancing the structural strength of the dental floss 10, improving its toughness and lifespan, and enabling the use of a single dental floss 10 to clean the entire mouth. On the other hand, the floss particles 12, which are flush with or protrude from the surface of the base 11, can form uneven structures or areas of varying hardness on the surface of the base 11, allowing the floss particles 12 to contact the teeth when cleaning them with the dental floss 10. This increases the friction generated when the dental floss 10 rubs against the teeth, effectively cleaning stubborn deposits such as plaque, and thus effectively preventing oral problems such as gingivitis and periodontitis, contributing to a healthy oral environment.

[0025] In some embodiments, the surface roughness of the cleaning particles 12 is greater than the surface roughness of the substrate 11. The cleaning particles 12 have a granular structure, and the surface roughness of the cleaning particles 12 is greater than the surface roughness of the substrate 11, resulting in a greater coefficient of friction between the cleaning particles 12 and the teeth than the coefficient of friction between the substrate 11 and the teeth.

[0026] Understandably, by combining the matrix 11 with the cleaning particles 12, the cleaning particles 12 generate greater friction when they rub against the teeth compared to the matrix 11. This can effectively clean stubborn deposits such as dental plaque, effectively prevent oral problems such as gingivitis and periodontitis, and promote oral health.

[0027] In some embodiments, the matrix 11 is a polyester rubber matrix.

[0028] It should be noted that, compared to other dental floss materials commonly used in related technologies, which are typically made of PE, PTFE (polytetrafluoroethylene), nylon, or cotton, PE floss is thin, silky, resistant to linting, and not easily broken. However, the small contact area between the thin PE floss and teeth results in generally lower cleaning efficiency, and the friction generated when PE floss rubs against teeth is usually low, leading to poor removal of stubborn deposits such as plaque. In addition, PE floss is usually quite sharp, which is not very friendly to people with sensitive gums. PTFE floss is soft, smooth, and less likely to damage gums, but PTFE floss lacks tensile strength and is prone to excessive deformation during use. This makes it less smooth and more likely to get stuck in areas such as between teeth. Furthermore, the friction generated when PTFE floss rubs against teeth is usually low, resulting in poor removal of stubborn deposits such as plaque.

[0029] In addition, although nylon floss can compensate for the lack of tensile strength, it is prone to fraying and splitting, which can easily damage the gums. Cotton floss, on the other hand, has problems such as high water absorption, easy breakage of single filaments, easy fraying, and short lifespan, which means that it is usually impossible to use a single piece of dental floss to clean all the teeth in the mouth.

[0030] In this application, the matrix 11 is made of polyester rubber (TPEE), also known as thermoplastic polyester elastomer, which is a linear block copolymer containing polybutylene terephthalate (PBT) as the hard segment and aliphatic polyester or polyether as the soft segment. On the one hand, the polyester rubber matrix is ​​safe and non-toxic, has a smooth surface, good resilience, is not prone to fuzzing, and is not prone to scattering. This results in less friction between the matrix 11 and the teeth, and it is less prone to fraying, splitting, and scattering. Consequently, the dental floss 10 causes less damage to the teeth and less irritation to the gum tissue. It also has sufficient tensile strength to glide smoothly back and forth, and is less likely to get stuck in areas such as between teeth, thus improving the user's cleaning comfort. On the other hand, the matrix 11 has sufficient strength, which gives the dental floss 10 sufficient durability, toughness, and service life, so that one piece of dental floss 10 can be used to clean the entire mouth.

[0031] In addition, polyester rubber combines the excellent elasticity of rubber with the easy processability of thermoplastics, giving it good processing performance, easy control of processing conditions, and high cost-effectiveness. This makes dental floss 10 easier to industrialize and offers good cost-effectiveness.

[0032] In some embodiments, the materials used to prepare the dental floss particles 12 may include one or more of the following: silica, calcium carbonate, calcium silicate, calcium phosphate, calcium pyrophosphate, molecular sieve zeolite, and hydroxyapatite. It should be noted that the materials listed in this embodiment are all commonly used abrasive materials in toothpaste, and have undergone long-term practical testing. They can generate strong friction with teeth while also being safe, reliable, and causing minimal irritation to the oral cavity, thus ensuring the reliability and comfort of the dental floss 10.

[0033] In some embodiments, the matrix 11 and the dental cleaning particles 12 are mixed and integrally molded, resulting in a stronger connection between the matrix 11 and the dental cleaning particles 12, and making the formation of dental floss 10 easier. The matrix 11 and the dental cleaning particles 12 can be integrally injection molded. When forming dental floss 10, the dental cleaning particles 12 can be placed in molten polyester rubber and stirred evenly to form a mixed material. Then, a specific single-screw or twin-screw plastic extruder is used to extrude the mixed material into sheets, tubes, rods, fibers, films, or other product forms. The products are then cured and processed to form dental floss 10.

[0034] See also Figure 1 and Figure 2 As shown, the width of the base 11 is d, and the thickness of the base 11 is h, where h < d, so that the base 11 is flattened, thus making the dental floss 10 as a whole flattened line. The flattened dental floss 10 can better match the shape of the narrow gaps between teeth. When using the dental floss 10 to clean the gaps between teeth, the dental floss 10 can be inserted into the gap from the top of the gap, with the narrow side (i.e., the thick side) of the dental floss 10 facing the bottom of the gap. The flattened dental floss 10 is easier to insert into the gap and slide back and forth in the gap. Where d can be set to: 0.2 mm ≤ d ≤ 5 mm. It is understandable that when d is less than 0.2 mm, the width of the base 11 is too small, resulting in a small contact area between the dental floss 10 and the teeth, thus reducing cleaning efficiency and the overall structural strength of the dental floss 10, thereby reducing its durability and lifespan. When d is greater than 5 mm, the width of the base 11 is too large, which will affect the insertion of the dental floss 10 into the interdental spaces and increase the cost of the dental floss 10. Here, d can be 0.2 mm, 1 mm, 2.5 mm, 3 mm, 5 mm, or other dimensions.

[0035] Furthermore, d can be set to 0.3 mm ≤ d ≤ 3 mm, ensuring that the dental floss 10 has sufficient width to guarantee cleaning efficiency and structural strength, while preventing the dental floss 10 from being too wide, which would increase costs. Here, d can be 0.3 mm, 1 mm, 1.5 mm, 3 mm, or other dimensions.

[0036] In some embodiments, d can be 1 mm, so that the base 11 has a width more suitable for the gaps between teeth, can cover a larger tooth surface, ensure that the dental floss 10 has sufficient width to ensure cleaning efficiency and structural strength, while preventing the dental floss 10 from being too wide and increasing costs.

[0037] In some embodiments, h can be set to: 0.01 mm ≤ h ≤ 0.5 mm. It is understood that when h is less than 0.01 mm, the thickness of the base 11 is too small, making the dental floss 10 too thin. This can easily damage the gums when the floss 10 comes into contact with them, causing significant discomfort to the user. Furthermore, the excessively small thickness can reduce the overall structural strength of the dental floss 10, thus reducing its durability and lifespan. When h is greater than 0.5 mm, the thickness of the base 11 is too large, making it difficult for the dental floss 10 to be inserted into the interdental spaces and causing it to slide poorly within the spaces. h can be 0.01 mm, 0.1 mm, 0.25 mm, 0.4 mm, 0.5 mm, or other sizes.

[0038] Furthermore, h can be set to 0.02 mm ≤ h ≤ 0.2 mm, ensuring that the dental floss 10 has sufficient thickness to guarantee structural strength and cleaning comfort, while preventing the dental floss 10 from being too thick and difficult to insert into the gaps between teeth. h can be 0.02 mm, 0.1 mm, 0.15 mm, 0.2 mm, or other sizes.

[0039] In some embodiments, h can be 0.1 mm, so that the base 11 has a thickness more suitable for the gaps between teeth, ensuring that the dental floss 10 can be easily inserted into the gaps between teeth, while preventing the dental floss 10 from being too thin and easily damaging the gums.

[0040] In some embodiments, the dental cleaning particles 12 are spherical, near-spherical, or ellipsoidal.

[0041] Understandably, the spherical dental cleaning particles 12 have the best fluidity, resulting in the lowest resistance during the mixing of the dental cleaning particles 12 with molten polyester rubber. This makes it easier for the dental cleaning particles 12 to be evenly dispersed in the molten polyester rubber. Furthermore, during the use of dental floss 10, the spherical dental cleaning particles 12 can make point contact with the tooth surface, resulting in a high concentration of contact stress on the teeth. This further enhances the cleaning effect of the dental cleaning particles 12 and makes it easier to remove stubborn dental plaque efficiently.

[0042] The spherical cleaning particles 12 can contact the tooth surface in a multi-point contact manner, which increases the probability of contact between the cleaning particles 12 and the tooth surface, thus making the cleaning particles 12 more abrasive to the teeth, but with stronger cleaning power.

[0043] The ellipsoidal teeth cleaning particles 12 have a large contact area with the tooth surface, which makes the contact stress on the teeth relatively dispersed. This results in less discomfort when the teeth cleaning particles 12 rub against the teeth, less wear on the teeth, and better cleaning comfort, allowing the cleaning particles to simultaneously achieve both cleaning power and cleaning comfort.

[0044] In some embodiments, the particle size of the cleaning particles 12 is r, which can be configured as: 1 micrometer ≤ r ≤ 50 micrometers. It is understood that when r is less than 1 micrometer, the particle size of the cleaning particles 12 is too small, resulting in excessively fine particles and a small contact area with the teeth, making it difficult for the cleaning particles 12 to significantly enhance friction and cleaning power. When r is greater than 50 micrometers, the particle size of the cleaning particles 12 is too large. When the most protruding cleaning particle 12 contacts the teeth, it can easily obstruct the contact between other cleaning particles 12 and the teeth. This excessively large particle size can actually reduce the effective contact area between all cleaning particles 12 and the teeth, and can also cause greater pressure and irritation to the gaps between teeth and the gums, resulting in greater discomfort for the user. r can be 1 micrometer, 10 micrometers, 25 micrometers, 30 micrometers, 50 micrometers, or other sizes.

[0045] Furthermore, r can be configured as: 15 mm ≤ r ≤ 25 mm, so that the particle size of the cleaning particles 12 is moderate, thereby enabling the cleaning particles 12 to not only significantly enhance friction and cleaning power, but also reduce the pressure and irritation caused by the cleaning particles 12 to the gaps between teeth and gums. Among them, r can be 15 micrometers, 20 micrometers, 25 micrometers or other sizes.

[0046] In some embodiments, r can be 20 micrometers. It should be noted that the abrasive particles in toothpaste are typically around 20 micrometers in size. Long-term practical testing has shown that teeth-cleaning particles 12 of approximately 20 micrometers can significantly enhance friction and cleaning power, while causing less pressure and irritation to the gaps between teeth and the gums. Furthermore, through numerous experiments by the inventors, it has been found that teeth-cleaning particles 12 of approximately 20 micrometers are more easily and uniformly diffused within the molten polyester rubber when mixed with it. This allows the teeth-cleaning particles 12 to be evenly distributed within the molded matrix 11, while also allowing some particles to be flush with or protrude from the surface of the matrix 11.

[0047] In some embodiments, the relative dentin abrasion value of the cleaning particles 12 is n, which can be configured as: 40 ≤ n ≤ 240. It is understood that the relative dentin abrasion value (RDA) is an indicator used to reflect the abrasive ability of particles on teeth; the larger the RDA, the stronger the abrasive ability of the particles on teeth. When n is less than 40, the cleaning ability of the cleaning particles 12 is weak, making it difficult to significantly enhance friction and cleaning power; when n is greater than 240, the abrasive effect of the cleaning particles 12 on teeth is excessive, easily causing significant damage to the enamel and potentially leading to exposure of dentinal tubules, even resulting in tooth sensitivity and pulp irritation, causing significant discomfort to the user. n can be 40, 100, 120, 150, 180, 240, or other values.

[0048] Furthermore, n can be configured as 100≤n≤150, so that the relative dentin abrasion value of the cleaning particles 12 is in a moderate state, which can significantly enhance the friction and cleaning power while reducing the damage and discomfort caused to the teeth by the cleaning particles 12. Among them, n can be 100, 120, 125, 150 or other values.

[0049] In some embodiments, the ratio of the total volume of all cleaning particles 12 to the volume of the matrix 11 is m, where m can be configured as: 3% ≤ m ≤ 30%. It is understood that the larger m is, the larger the total volume of the cleaning particles 12, resulting in a greater probability, frequency, and coverage density of contact between the cleaning particles 12 and the teeth, thus enhancing the cleaning efficiency and effect of the cleaning particles 12. When m is less than 3%, the total volume of the cleaning particles 12 is too small, resulting in a low probability, frequency, and coverage density of contact between the cleaning particles 12 and the teeth, making it difficult for the cleaning particles 12 to significantly enhance friction and cleaning power. When m is greater than 30%, the total volume of the cleaning particles 12 is too large, leading to excessive wear on the enamel and irritation to the gums. Furthermore, excessive addition of cleaning particles 12 can reduce the toughness of the dental floss 10, making it more prone to breakage. Here, m can be 3%, 10%, 15%, 20%, 30%, or other proportions.

[0050] In some embodiments, m can be 20%, which allows the dental cleaning particles 12 to significantly enhance friction and cleaning power, while preventing excessive wear of the enamel and irritation to the gums, and preventing excessive addition of dental cleaning particles 12 from reducing the toughness of the dental floss 10.

[0051] like Figure 3 and Figure 4 As shown, in some embodiments, the substrate 11 can be a white translucent substrate (e.g., Figure 3) or transparent substrate (such as Figure 4 This design allows users to see the cleaning particles 12 within the base 11, providing a more intuitive understanding of the improved cleaning power of the dental floss 10. It also enhances the aesthetics and fun of using the dental floss 10, making it more suitable for children. Furthermore, during the production process, quality control personnel can more easily observe the distribution of the cleaning particles 12, facilitating quality inspection and preventing consumers from receiving substandard dental floss 10.

[0052] like Figures 5 to 7 As shown, in some embodiments, the teeth-cleaning particles 12 can be colored particles, or they can be white particles (e.g., white particles). Figure 5 Teeth cleaning particles 12 can also be yellow, pink, red, blue, green, or other colored particles, and all teeth cleaning particles 12 can be the same color (e.g., ...). Figure 6 ) or different (e.g. Figure 7 It is understandable that colored particles are more visible, allowing users to see more clearly the distribution of the teeth-cleaning particles 12 within the matrix 11. Furthermore, colored particles offer greater aesthetic appeal and fun, making them more suitable for children.

[0053] In addition, the type of dental floss can be distinguished by the color of the dental floss particles 12, making it easier for users to purchase and select the type of dental floss they need. For example, green dental floss particles 12 are for fresh breath, purple dental floss particles 12 are for preventing cavities, red dental floss particles 12 are for strawberry-scented dental floss, and green dental floss particles 12 are for watermelon-scented dental floss.

[0054] Secondly, based on the aforementioned dental floss 10, this application also provides a dental floss pick, such as... Figure 8 As shown, the dental floss pick includes a handle 20 and dental floss 10 as described in any of the above embodiments. The handle 20 includes a stem 21 and a mounting portion 22 connected to the stem 21, and the dental floss 10 is mounted on the mounting portion 22.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
