Description

[Technical Field]

[0001] [CROSS-REFERENCE TO RELATED APPLICATIONS] This application claims priority from Chinese Utility Model Application No. 202421724630.9, filed on July 19, 2024, the disclosure of which is incorporated herein by reference.

[0002] This application relates to the field of dental cleaning tools, and in particular to monofilament dental tape, dental floss rolls made from monofilament dental tape, and dental floss sticks made from monofilament dental tape. [Background technology]

[0003] Monofilament dental tape is a tool used to clean between teeth. It removes food debris and plaque from between teeth through friction and translation. To slide smoothly between teeth, the thickness of the monofilament dental tape must be sufficiently thin. However, if the thickness is too thin, it will have a negative effect on the tensile strength of the monofilament dental tape, making it more likely to break when pulled. To effectively scrape away food debris and plaque from the tooth surface, the side of the monofilament dental tape that comes into contact with the tooth surface should have an uneven structure. However, this structure increases the thickness of the monofilament dental tape, making it difficult to slide between teeth.

[0004] It would be desirable to develop a monofilament dental tape that slides easily between teeth, has some tensile strength, and has a structure that helps effectively scrape food particles and plaque off of the tooth surface. Summary of the Invention

[0018]

[0013] Exemplary embodiments of the present application are described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are illustrated in the accompanying drawings, it should be understood that the present application may be embodied in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more complete understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0019] FIG. 1 is a perspective view of a monofilament dental tape according to a first embodiment of the present application. In this specification, the direction in which the monofilament dental tape 1 extends is defined as the length direction or first direction (i.e., the arrow direction x in FIG. 1 ), the direction perpendicular to one side of the monofilament dental tape is defined as the width direction or second direction (i.e., the arrow direction y in FIG. 1 ), and the direction perpendicular to the length direction and width direction is defined as the height direction or third direction (i.e., the arrow direction z in FIG. 1 ). The monofilament dental tape 1 has a long, narrow strip shape extending along the length direction x and includes a wavy section 10 in a cross section along the width direction y. The monofilament dental tape 1 may further include a guide section 2 disposed at the edge of the wavy section 10.

[0020] FIG. 2 is a cross-sectional view of the monofilament dental tape of FIG. 1. FIG. 3 is a partially enlarged schematic view of the wavy section of FIG. 2, showing one wave unit and multiple secondary wave units superimposed thereon. The wavy section 10 includes a first wavy portion 100 and a second wavy portion 101. The first wavy portion 100 includes six wave units connected in series. The wave units are triangular in shape. The second wavy portion 101 includes one or more secondary wave units superimposed on a wave unit of the first wavy portion 100. The secondary wave units are sinusoidal in shape. Specifically, the secondary wave units are superimposed at a length that is one-quarter of that of each wave unit in the first wavy portion 100 of the wavy section 10. The wavelength h4 of each wave unit in the first wavy portion 100 is greater than the wavelength h5 of each secondary wave unit in the second wavy portion 101. The amplitude h7 of each wave unit of the first wavy portion 100 is greater than the amplitude h6 of each secondary wave unit of the second wavy portion 101.

[0021] The guide section 2 is disposed on the edge of the wavy section 10 and includes a connecting portion 21 close to the wavy section 10 and a guide portion 22 remote from the wavy section 10. The width h8 of the guide section 2 is approximately 120 μm. The guide portion 22 has a smoothly extending arc-shaped surface.

[0022] In the embodiment of FIG. 1, the monofilament dental tape is made from 30 wt% Hytrel® 5556 (a polyetherester thermoplastic elastomer), 65 wt% Hytrel® 4068FG (a polyetherester thermoplastic elastomer), and 5 wt% Multibase™ MB50-010 (a polyetherester thermoplastic elastomer lubricant masterbatch).

[0023] When the monofilament dental tape 1 is not subjected to external force, the thickness h1 of the wavy section 10 is 70 μm. The height h3 of the wavy section 10 is 100 μm. The width h2 of the wavy section 10 is 1600 μm.

[0024] The wavelength h4 of the wave unit is about 260 μm, the amplitude h7 is about 15 μm, and the wave unit has a rounded profile at the turning portion. The wavelength h5 of the secondary wave unit is about 84 μm, and the amplitude h6 is about 3 μm.

[0025] The wavy section 10 formed by overlapping the first wavy section 100 and the second wavy section 101 can increase the roughness and cleaning power of the monofilament dental tape without affecting its compressibility and ability to penetrate between teeth. The wavelength h4 and amplitude h7 of the wave units of the first wavy section 100 are relatively large, forming the basic structure of the wavy section 10 that gives the monofilament dental tape good compressibility and ability to penetrate between teeth. The wavelength h5 and amplitude h6 of the secondary wave units of the second wavy section 101 are relatively small, mainly serving to increase the roughness of the monofilament dental tape, thereby improving its cleaning power.

[0026] It can be understood that the traveling direction of the secondary wave units of the second wavy portion 101 changes along the contour direction of the first wavy portion 100 to achieve the above technical effect.

[0027] It is understood that the thickness of the wavy section 10 can be uniform or non-uniform to achieve the above technical effect. In the latter case, the maximum thickness of the wavy section 10 does not exceed six times, and preferably does not exceed two times, the minimum thickness. The thickness h1 of the wavy section 10 can be in the range of 20 to 120 μm, preferably in the range of 30 to 90 μm, and more preferably in the range of 40 to 80 μm. The width h2 of the wavy section 10 can be in the range of 700 to 3000 μm, preferably in the range of 700 to 2000 μm, and more preferably in the range of 1000 to 2000 μm. The height h3 of the wavy section 10 can be in the range of 40 to 200 μm, preferably in the range of 60 to 170 μm, and more preferably in the range of 80 to 150 μm.

[0028] It can be understood that to achieve the above technical effects, the first wavy portion 100 of the wavy section 10 can have 2 to 25 wave units, preferably 5 to 10 wave units. The wavelength h4 of the wave units in the first wavy portion 100 of the wavy section 10 can be in the range of 60 to 800 μm, preferably in the range of 100 to 600 μm, and more preferably in the range of 150 to 500 μm. The amplitude h7 of the wave units in the first wavy portion 100 of the wavy section 10 can be in the range of 0 to 90 μm, preferably in the range of 2 to 50 μm, and more preferably in the range of 3 to 25 μm.

[0029] It can be understood that to achieve the above technical effects, the wavelength h5 of the secondary wave unit in the second wavy portion 101 of the wavy section 10 can be in the range of 20 to 600 μm, preferably in the range of 30 to 400 μm, and more preferably in the range of 40 to 200 μm. The amplitude h6 of the secondary wave unit in the second wavy portion 101 of the wavy section 10 can be in the range of 0 to 50 μm, preferably in the range of 1 to 25 μm, and more preferably in the range of 2 to 15 μm.

[0030] It can be understood that in order to achieve the above technical effect, the wavelength h4 of the wave unit in the first wavy portion 100 of the wavy section 10 is not more than 20 times the wavelength h5 of the secondary wave unit in the second wavy portion 101 of the wavy section 10, preferably not more than 10 times, more preferably not more than 4 times.

[0031] To achieve the above technical effects, the monofilament dental tape 1 can be made of a polyamide thermoplastic elastomer, a polyetherester thermoplastic elastomer, a polyolefin thermoplastic elastomer, a thermoplastic polyurethane elastomer, a styrene block copolymer elastomer, a polyolefin with a tensile modulus of less than 1 GPa, or a polybutylene succinate with a tensile modulus of less than 1 GPa. The monofilament dental tape 1 is preferably made of a polyamide thermoplastic elastomer or a polyetherester thermoplastic elastomer. More preferably, the monofilament dental tape 1 is made of a polyetherester thermoplastic elastomer.

[0032] Although not shown, it is understood that the monofilament dental tape of the present application may also include a coating applied to the surface thereof, which may consist of a lubricating agent, a release agent, an abrasive agent, a whitening agent, an active agent, an olfactory stimulant, a salivating agent, an organoleptic stimulant, an essential oil, a spice, an antibacterial agent, or an antiviral agent.

[0033] 4 is a partial schematic diagram of a wavy section 10 of a monofilament dental tape 1 according to another embodiment of the present application, showing one wave unit and multiple secondary wave units superimposed thereon. Compared to FIG. 3, the wave units of the first wavy portion 100 in FIG. 4 are still triangular in shape, while the secondary wave units of the second wavy portion 101 are also triangular in shape.

[0034] 5 is a partial schematic diagram of a wavy section 10 of a monofilament dental tape 1 according to another embodiment of the present application, showing one wave unit and multiple secondary wave units superimposed thereon. Compared to FIG. 3, the shape of the wave units of the first wavy portion 100 in FIG. 5 is still triangular, while the shape of the secondary wave units of the second wavy portion 101 is sinusoidal.

[0035] 6 is a partial schematic diagram of a wavy section 10 of a monofilament dental tape 1 according to another embodiment of the present application, showing one wave unit and multiple secondary wave units superimposed thereon. Compared to FIG. 3, the wave units of the first wavy portion 100 in FIG. 6 are sinusoidal in shape, and the secondary wave units of the second wavy portion 101 are still sinusoidal in shape, but three secondary wave units are superimposed at half the length of each wave unit in the first wavy portion 100 of the wavy section 10.

[0036] 7 is a partial schematic diagram of a wavy section 10 of a monofilament dental tape 1 according to another embodiment of the present application, showing one wave unit and multiple secondary wave units superimposed thereon. Compared to FIG. 3, the wave units of the first wavy portion 100 in FIG. 7 have a rectangular shape, and the secondary wave units of the second wavy portion 101 also have a rectangular shape.

[0037] It can be understood that in order to obtain the above-mentioned technical effects, the first wavy portion 100 of the wave unit having the above-mentioned shape (triangle, arc, sine wave, rectangle, other polygon, etc.) and the second wavy portion 101 of the secondary wave unit having the above-mentioned shape (triangle, arc, sine wave, rectangle, other polygon, etc.) can be arbitrarily combined, and all are within the protection scope of the present application.

[0038] 8 is a partial schematic diagram of a wavy section of a monofilament dental tape according to another embodiment of the present application, showing two wave units of the same shape and multiple secondary wave units stacked thereon. Compared to FIG. 3, the wave units of the first wavy portion 100 in FIG. 8 have an arc-shaped shape, while the secondary wave units of the second wavy portion 101 have a sinusoidal wave shape. Furthermore, in FIG. 8, a straight section 102 connects the two wave units of the first wavy portion 100.

[0039] FIG. 9 is a partial schematic diagram of a wavy section of a monofilament dental tape according to another embodiment of the present application, showing two wave units of different shapes and multiple secondary wave units superimposed thereon. Compared to FIG. 8, the first wavy section 100 in FIG. 9 is formed by consecutively connecting a triangular wave unit and a sinusoidal wave unit. The secondary wave unit superimposed on the triangular wave unit of the second wavy section 101 is triangular, while the secondary wave unit superimposed on the sinusoidal wave unit is sinusoidal. Furthermore, in FIG. 9, no straight section 102 is interposed between the first wavy sections 100.

[0040] The following describes the process by which the monofilament dental tape advances between teeth based on an embodiment of the present application. As the monofilament dental tape slides over the occlusal surfaces of the teeth, the guide section 2 of the monofilament dental tape catches on the interdental opening, thereby generating feedback for the object pulling the dental tape (such as a hand, a dental floss roll, or a dental floss stick). In this way, the user of the monofilament dental tape can clearly sense the position of the monofilament dental tape and then change the direction of the force applied to the monofilament dental tape. After the direction of the force applied to the monofilament dental tape is changed from parallel to the occlusal surfaces of the teeth to perpendicular to the occlusal surfaces of the teeth, the monofilament dental tape reciprocates over the interdental opening under the action of the combined forces, so that the dental tape body 1 extends from the interdental opening into the interdental space along the width direction y. As the monofilament dental tape moves back and forth between the teeth along the width direction y, the wavy section 10 of the dental tape body 1 comes into contact with the surface between the teeth, and as a result, food debris between the teeth and plaque on the tooth surface are pushed into the grooves formed by the first wavy portion 100 and the second wavy portion 101 of the wavy section 10, and are then pulled out from between the teeth as the monofilament dental tape moves.

[0041] The monofilament dental tape according to the present invention has the following technical advantages. The dental tape body 1 of the monofilament dental tape has increased strength along the width direction y, making it less susceptible to cracking and fractures along the length direction x. The dental tape body 1 of the monofilament dental tape enhances the cleaning effect of the dental tape on the tooth surface. The combination of the guide section 2 of the monofilament dental tape with the dental tape body 1 ensures uniform and stable sliding resistance of the monofilament dental tape as it penetrates between teeth. When the interdental width suddenly changes, the dental tape body 1 is pulled along the width direction y to flatten it, absorbing the tension along the width direction y. This prevents the sudden release of tension caused by a sudden change in interdental width, which could damage the gums.

[0042] The present application also includes a dental floss roll made of monofilament dental tape and a dental floss stick made of monofilament dental tape, which have the same technical effects as monofilament dental tape.

[0043] The following describes an experiment on the cleaning effectiveness of dental tape, which includes the following steps:

[0044] Step 1: Using a crayon, apply 20 strokes to the enamel surface of the flat part of the canine sample to form a colored strip approximately 1.5 mm wide.

[0045] Step 2: Pull the dental tape between your fingers so that approximately 3cm of dental tape remains between your fingers.

[0046] Step 3: Rub the dental tape across the enamel surface three times in the direction of the staining strip, using a clean area of ​​the dental tape each time.

[0047] Step 4: Score the remaining colored strip, assigning a score of 5 if the colored strip is completely removed and a score of 1 if it is not removed at all.

[0048] The above test was repeated three times for each dental tape sample and the average value was calculated.

[0049] Below is described an experiment on the dental tape's ability to move in and out between teeth, which includes the following steps:

[0050] Step 1: Fix the two ends of the dental tape to the two arms of the arcuate tooling, respectively, so that the length of the dental tape between the two fixing points is approximately 4 cm.

[0051] Step 2: Connect the tooling to a handheld force gauge with a range of 20 N.

[0052] Step 3: Adjust the distance between the fixed anvil and the movable anvil of the micrometer screw with two round-end anvils to 30 μm, and fix the micrometer screw to the table.

[0053] Step 4: While holding the force gauge with one hand, apply a force vertically downward to the dental tape fixed to the tooling until the dental tape passes through the gap between the two round-end anvils of the micrometer screw, and read the maximum force on the force gauge as the interdental advance force.

[0054] Step 5: While holding the force gauge with one hand, apply a force vertically upward to the dental tape that has passed through the gap, so that the dental tape passes through the gap between the two round-end anvils of the micrometer screw, and read the maximum force on the force gauge as the interdental retraction force.

[0055] A new dental tape sample is replaced and the above test is repeated six times to calculate the average interdental advancement force and interdental retraction force.

[0056] The monofilament dental tape of the above embodiment (i.e., Example 1 in the following table) was tested and compared to other dental tapes of the prior art, the results of which are shown in the following table.

[0057] [Table 1]

[0058] In the above table, Comparative Example 1 is the commercially available product Oral B Glide Comfort Plus Floss made from polytetrafluoroethylene.

[0059] Comparative Example 2 is a monofilament dental tape made from 30 wt% Hytrel® 5556, 65 wt% Hytrel® 4068FG, and 5 wt% Multibase™ MB50-010. The monofilament dental tape of Comparative Example 2 has a total width of approximately 1600 μm and includes a guide section and a wavy section having seven triangular wave units in a cross section along the width direction y. The wavelength of each wave unit is approximately 200 μm, and the amplitude is approximately 15 μm. The height of the wavy section is approximately 105 μm, and the thickness is approximately 70 μm. The width of the guide section is approximately 120 μm.

[0060] Embodiment 1 is a monofilament dental tape 1 according to the present application, as shown in FIG.

[0061] From the table above, it can be seen that the monofilament dental tape according to the present application has a higher cleaning ability and a lower interdental advancement and retraction force than commercially available products. Compared to a monofilament dental tape having only a single wavy section, a monofilament dental tape according to the present application in which a second wavy section with a smaller wavelength and amplitude is superimposed on a first wavy section has a better cleaning ability.

[0062] The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the variations described. Many modifications and variations will be apparent to those skilled in the art. These embodiments have been chosen and described to best explain the principles and practical applications so that those skilled in the art can understand the embodiments in various embodiments and various modifications suitable for their intended use.
