Description

Technical Field

[0001] The utility model relates to an adjustable bending dental floss stick, which is characterized in that a bendable portion with a bending function is arranged in the middle of the gripping and pressing portion of the adjustable bending dental floss stick, so that the adjustable bending dental floss stick can be bent left and right with the bendable portion as the center, and then the dental floss is bent so that the dental floss can be in a tight or loose state. Background Art

[0002] Dental plaque is a biofilm that gradually builds up around the tooth surface and is responsible for many periodontal diseases, such as gingivitis or periodontitis. The main cause of dental plaque formation is poor daily oral hygiene, i.e. failure to follow effective oral cleaning methods, which results in bacteria adhering to the tooth and gum surfaces.

[0003] Therefore, modern people use oral cleaning tools such as toothbrushes, toothpicks, dental floss, dental floss sticks or mouthwashes to clean their oral cavity. In particular, in order to remove food residues between teeth, dental floss or dental floss sticks are generally used for cleaning.

[0004] The dental floss sticks on the market are roughly divided into F-type dental floss sticks and Y-type dental floss sticks. In terms of use, F-type dental floss sticks are more suitable for cleaning the front teeth; Y-type dental floss sticks are more suitable for cleaning the back teeth. However, the dental floss on the dental floss sticks is designed in a linear shape, that is, the dental floss is in a tight state. Therefore, in use, due to improper use or incorrect force by the user, the dental floss on the dental floss stick is prone to breakage and damage to the teeth, and it is not possible to effectively clean the gaps between teeth and the surface of the teeth. Therefore, the current design of linear dental floss sticks has its defects in tooth cleaning. In addition, the dental floss of the tight dental floss sticks currently on the market will irritate or even damage the gums when used, and long-term use will cause gum atrophy, which will cause another oral disease. Dental floss is a standard tool recommended by dentists and other professionals for oral cleaning. However, the public must undergo education and training before using it. It requires certain skills and is relatively troublesome to use, making it difficult to promote and apply.

[0005] In view of the above inconveniences, it is necessary to develop a new type of dental floss stick to help users who are not good at using dental floss or dental floss sticks, and people who need to clean their teeth quickly, effectively and correctly, so that they can clean the gaps between teeth more easily to achieve the purpose of oral hygiene and health care. Utility Model Content

[0006] The utility model provides an adjustable bending dental floss stick, which comprises: a dental floss rack, which has two side arms and a connecting part, the two side arms respectively have a first end away from the connecting part and a second end connected to the connecting part, the first ends are connected to dental floss, and the second ends are respectively connected to the front half of the connecting part; and a gripping and pressing part, which has a front end connected to the connecting part and a rear end away from the connecting part, the front end is connected to the rear half of the connecting part, and a bendable part is provided in the middle of the gripping and pressing part, wherein the bendable part is used to bend the gripping and pressing part to the left and right sides, and drive the two side arms to bend the dental floss together.

[0007] In a specific embodiment, the two side arms and the connecting portion form a U-shaped or V-shaped structure.

[0008] In a specific embodiment, the connecting portion, the two side arms and the gripping and pressing portion of the adjustable bending dental floss holder are integrally formed. In addition, the gripping and pressing portion and the two side arms are respectively located at different positions of the connecting portion, for example, the two side arms are located at the front half of the connecting portion, and the gripping and pressing portion is located at the rear half of the connecting portion.

[0009] In the present invention, the material of the dental floss can be a common dental floss material known to those skilled in the art. The dental floss material is generally a soft polymer material, such as nylon, polyester fiber, acrylic fiber, polyethylene, Teflon, plant fiber material or silk. In a specific embodiment, the material of the dental floss includes nylon, Teflon, plant fiber material or silk. In addition, the dental floss can be artificial fiber or braided dental floss, waxed or wax-free, round dental floss and flat dental floss, or dental floss with added flavors such as mint and xylitol or substances for preventing dental caries. In some aspects, the two ends of the dental floss are respectively connected to the first ends of the two side arms.

[0010] In the present invention, the material of the adjustable bendable dental floss stick (such as the connecting portion, the two side arms and the gripping and pressing portion) is a soft elastic material. Therefore, when the adjustable bendable dental floss stick is bent left and right by applying force from the left and right sides of the bendable portion, the adjustable bendable dental floss stick will not break during normal use. However, through the material selection and manufacturing process design, the user can break the dental floss stick through the bendable portion after use to avoid secondary use or other infection and contamination.

[0011] In some embodiments, the material of the dental floss stick includes a plastic material. In a specific embodiment, the plastic material includes polypropylene (PP), polystyrene (PS), ABS (Acrylonitrile butadiene styrene) resin / acrylonitrile-butadiene-styrene copolymer, polyethylene terephthalate (PET), polyamide (PA), polyethylene (PE), polyurethane (PU), polycarbonate (PC) or high-density polyethylene (HDPE). The material of the dental floss stick has a certain degree of elasticity and does not contain harmful substances that are harmful to human health. Since the material of the dental floss stick is elastic, the dental floss stick can be bent appropriately.

[0012] In some aspects, the gripping and pressing portion is a portion for the user to grip. In general, the gripping and pressing portion is in the shape of a rod. However, considering that the utility model needs to design a long strip of the bendable portion (such as a groove) in the middle of the gripping and pressing portion, the gripping and pressing portion of the utility model is an elongated member with a certain width to accommodate the bendable portion (such as a groove).

[0013] In the utility model, the function of the bendable portion is to provide a place for applying force to bend. Therefore, the bendable portion is a component with a bending function. One of the forms of the bendable portion is a bendable groove, and the groove is designed in the middle of the gripping and pressing portion, so that the left and right sides of the gripping and pressing portion (i.e., the left and right sides of the gripping and pressing portion adjacent to the groove) can be bent with the groove as the center. In a specific embodiment, the groove can be designed to be V-shaped or ㄩ-shaped. By bending the groove to achieve the bending state of the two side arms of the dental floss stick, the dental floss will become a C-shaped or even U-shaped. Of course, the bottom of the groove and the bevel angles on its left and right sides can also be designed to be asymmetrical according to needs, that is, the angles on the left and right sides of the groove present an asymmetrical angle or angle. The groove and the bevel angle design therein will affect the maximum angle at which the adjustable bendable dental floss stick can be bent, and then affect the tightness of the dental floss, that is, the shape of the dental floss will be different. Different shapes of dental floss can be applied to different teeth. Therefore, the utility model allows the dental floss to have different tightness and shapes through different grooves and bending angles to meet different teeth cleaning needs.

[0014] In the present invention, the groove can be arranged in the middle of the top surface or the bottom surface of the gripping and pressing portion, or in the middle of both surfaces. Therefore, the bendable portion can be arranged in the middle of one or both surfaces of the gripping and pressing portion. In a specific embodiment, the bendable portion is arranged on the top surface and / or the bottom surface of the gripping and pressing portion. Therefore, the gripping and pressing portion in the adjustable bendable dental floss stick of the present invention can be designed to have a groove on one side or on both sides. Since the groove has a bendable function, the design of having grooves on both sides allows the adjustable bendable dental floss stick to be bent to different sides or directions.

[0015] In the present invention, the gripping and pressing portion can be regarded as an independent component of the left and right halves, namely the gripping and pressing portion of the left half and the gripping and pressing portion of the right half. When the gripping and pressing portion is divided into the left and right halves, each forming an independent component, the bendable portion located in the middle of the gripping and pressing portion forms a connecting component of the left and right halves of the gripping and pressing portion. Therefore, the bendable portion can be used as a connecting component to connect the left and right halves of the gripping and pressing portion, while still having a bendable function. In a specific embodiment, the gripping and pressing portion is divided into the left and right halves, and the bendable portion forms a connecting component to connect the left and right halves of the gripping and pressing portion.

[0016] The gripping and pressing part on the adjustable bendable dental floss stick of the utility model can have different designs. For example, the central part of the gripping and pressing part can be designed to be hollow, and the bendable part is respectively arranged at the front end and the rear end of the hollow part. Such a design can also facilitate the user to bend the adjustable bendable dental floss stick. In a specific embodiment, the central part of the gripping and pressing part is hollow, and the bendable part is respectively arranged at the front end and the rear end of the gripping and pressing part.

[0017] In addition, considering that users sometimes place the dental floss stick on a desktop or other flat surface, there is a risk that the dental floss will touch the desktop, which will cause hygiene problems. Therefore, the utility model proposes a design in which the horizontal height of the dental floss holder is higher than the horizontal height of the gripping and pressing portion. This design is to convert the connecting portion into an arc-shaped structure, which bends upward from the gripping and pressing portion to the extension direction of the two side arms, so that the dental floss holder is at a higher horizontal plane than the gripping and pressing portion. In a specific embodiment, the connecting portion is an arc-shaped structure, which bends upward from the gripping and pressing portion to the extension direction of the two side arms, so that the dental floss holder is higher than the gripping and pressing portion. With such a design, when the adjustable bending dental floss stick is placed on the desktop, the gripping and pressing portion will touch the desktop, but the horizontal height of the dental floss holder will be higher than the gripping and pressing portion. Therefore, the dental floss on the dental floss holder will not touch the desktop at all, and the hygiene of the dental floss can be ensured.

[0018] Furthermore, the utility model can add protrusions to the bottom surface of the gripping and pressing portion (the side that will contact a plane (such as a desktop)), for example, protrusions are provided on the bottom surfaces of the front and rear ends of the gripping and pressing portion. The function of the protrusions is to raise the adjustable bending dental floss stick and to keep the adjustable bending dental floss stick in a stable state when placed on a plane. In a specific embodiment, the bottom surfaces of the front and rear ends of the gripping and pressing portion each have a protrusion, which prevents the dental floss holder from contacting the plane when the adjustable bending dental floss stick is placed on a plane. Therefore, when the adjustable bending dental floss stick is placed on a plane, only the protrusion will contact the plane, and the adjustable bending dental floss stick as a whole will not contact the plane to keep the dental floss hygienic.

[0019] In some aspects, the two side surfaces of the gripping and pressing portion are designed to be long strips with the same or different thicknesses. In addition, the contact area of ​​a portion of the two side surfaces of the gripping and pressing portion can be increased, for example, by designing it into an elliptical shape. The benefit of increasing the contact area is that the user's fingers hold the adjustable bending dental floss pick with a larger force application area. In a specific embodiment, the two side surfaces of the gripping and pressing portion are elliptical in shape for pressing and applying force.

[0020] In the utility model, a non-slip portion may be provided on the gripping and pressing portion, which may be provided on the top surface, side surface or bottom surface of the gripping and pressing portion. The function of the non-slip portion is to facilitate the user to hold the adjustable bending dental floss stick firmly. In some aspects, the non-slip portion is a component with a concave-convex structure. The friction between the contact with the finger is increased by the design of the concave-convex shape. Therefore, when the user's finger presses the non-slip portion on the gripping and pressing portion, it is more convenient to hold the adjustable bending dental floss stick firmly. In a specific embodiment, the gripping and pressing portion further includes a non-slip portion, which is provided on the top surface, side surface or bottom surface of the gripping and pressing portion to facilitate gripping.

[0021] In some aspects, the gripping and pressing portion can be designed in shape or structure according to mechanics and / or ergonomics, or an additional pressing member can be designed to facilitate the user to operate the bending and use the adjustable bending dental floss stick. The utility model can further design pressing members on the left and right sides of the gripping and pressing portion to provide a better force application position when the user applies force from the left and right sides of the gripping and pressing portion to bend. In other words, the user bends the dental floss stick to the left and right by pressing the pressing members on the left and right sides of the gripping and pressing portion. Therefore, the pressing member can be designed as a component with a larger area to facilitate the user's fingers to press. In a specific embodiment, the left and right sides of the gripping and pressing portion are respectively connected to a first pressing member, which is used for pressing and applying force. The shape of the pressing member is not limited, and can be semicircular, semi-elliptical, square or rectangular. In addition, no matter how the pressing member is configured, it does not affect the bending function of the dental floss stick of the utility model. In another specific embodiment, the pressing member and the gripping and pressing portion are an integrally formed structure.

[0022] In the present invention, the pressing member can also be designed at any position on the outer side of each of the two side arms. For example, a pressing member can be connected to the outer side of the right arm, and a pressing member can be connected to the outer side of the left arm. Therefore, the outer sides of the two side arms each have a pressing member, and the user can also bend the dental floss stick left or right by applying force to press the two pressing members. In a specific embodiment, the two side arms are respectively connected to a single outer side with a second pressing member, which is used for pressing and applying force.

[0023] In addition, if the dental floss is directly fixedly connected to the two side arms of the dental floss stick, the user will discard the entire dental floss stick after using the dental floss stick. Therefore, the utility model also proposes a design that allows the adjustable bending dental floss stick to be reused. In this design, the utility model can design a perforation at the first end of the two side arms on the adjustable bending dental floss stick, and the purpose of the perforation is to allow the dental floss to pass through and be wound and fixed. Therefore, the two ends of the dental floss are wound and fixed on the two perforations. Furthermore, after the dental floss passes through and is wound around the two perforations, one end of the dental floss is fixed on one of the perforations, and the other end is wound and fixed on a single pressing member. Since the dental floss is fixed by passing through and winding around the perforation or the pressing member, rather than being directly fixedly connected to the two side arms of the dental floss stick. The dental floss can be removed from the adjustable bending dental floss stick, and new dental floss can be rewound and fixed on the adjustable bending dental floss stick. Therefore, after the user has finished using the dental floss, the dental floss can be removed from the adjustable curved dental floss stick, and the adjustable curved dental floss stick itself can be retained; and then new dental floss can be reinstalled on the adjustable curved dental floss stick. Such a design allows the adjustable curved dental floss stick itself to be reused, as long as the dental floss is replaced. In a specific embodiment, the first ends of the two side arms respectively have through holes, wherein one end of the dental floss passes through and is wrapped around the through holes on the first ends of the two side arms, and the other end thereof is wrapped around and fixed on the first pressing member or the second pressing member.

[0024] In addition, the present invention can also provide other components for winding dental floss, which are used to fix the dental floss passing through the perforation. The dental floss winding component can be designed at any position on the adjustable bending dental floss stick, and the function of the dental floss winding component is only to provide a position for winding and fixing the dental floss, and does not provide a pressing effect. For example, a hole is punched on the gripping and pressing part structure to facilitate the winding and fixing of the dental floss.

[0025] The utility model is designed to set the bendable part in the middle of the holding and pressing part, so that when the user applies force on the left and right sides of the holding and pressing part, the adjustable bendable dental floss stick can be bent left and right with the bendable part as the center, that is, in addition to the bending of the left and right sides of the holding and pressing part, the two side arms on the connecting part will also bend left and right. Since the two side arms will also bend left and right, the dental floss connected between the two side arms will also bend accordingly. Therefore, when the adjustable bendable dental floss stick is not bent, the dental floss is in a tight state, for example, the dental floss presents a straight line. When the adjustable bendable dental floss stick is bent, the dental floss will become C-shaped or U-shaped, that is, the tension / stress of the dental floss becomes lower. When the user bends the adjustable bendable dental floss stick, the dental floss can be in a C-shaped or even U-shaped shape, at which time the stress of the dental floss is reduced, which can reduce the damage to the teeth or gums when cleaning the teeth. Therefore, a C- or U-shaped dental floss is the most suitable for covering teeth and the gaps between teeth and gums to achieve the purpose of effective tooth cleaning. Therefore, the present invention allows the dental floss stick to be bent left and right, so that the dental floss on the dental floss stick can be adjusted to a C- or U-shaped form. This design is not only convenient to use, but also takes into account the safety and effectiveness of the use of the dental floss stick, ultimately achieving the purpose of effective tooth cleaning.

[0026] Therefore, the core concept of the present invention is a dental floss stick that can be bent in a mirror or non-mirror direction, and the direction of the mirror / non-mirror bending and the dental floss direction can be designed at various angles according to user needs, especially a parallel angle can achieve the best effect. In this way, the mirror / non-mirror bending can change the dental floss on the dental floss stick from a tight state to a loose state.

[0027] Generally speaking, dental floss in a tight state can be used to pass through the gaps between teeth; while dental floss in a loose state can naturally form a C or even U shape according to the bending angle of the dental floss stick, achieving the safe and effective purpose of cleaning teeth without damaging teeth and gums. Therefore, when the dental floss is in a C or even U shape, it is most suitable for covering teeth and the gaps between teeth and gums. The use of existing dental floss requires a lot of practice and even training for users to learn how to wrap the dental floss around their fingers to make the dental floss present a C or U shape to clean teeth and oral cavity. The utility model can help users, by utilizing the inherent design of the dental floss stick, achieve the state of making the dental floss present a C or U shape by bending the dental floss stick with almost no training requirements. Since the dental floss can be adjusted to a C or U shape, it will not damage teeth or gums due to the stress of the tight dental floss like the existing general dental floss stick.

[0028] A bendable portion is designed in the center of this dental floss stick, which can be manufactured using general mold design and plastic injection molding. The dental floss stick body can be equipped with a handle or fixed point suitable for ergonomics (human factors engineering) / finger force, which is convenient for bending or unfolding. However, whether or not other ergonomic handles or fixed points are further equipped does not affect or limit the present invention. The conception and practice of the present invention is to bend the inherent body of the dental floss stick to form a dental floss that can be adjusted to a tight and C or U-shaped shape, so that correct use and convenient operation can be naturally achieved, while taking into account the safety and effectiveness of the use of the dental floss / dental floss stick. This design can also meet the needs of dentists who need dental floss sticks and dental floss with customized angles according to the oral and tooth structures of certain patients when treating their mouths and teeth.

[0048] The following embodiments are non-limiting and merely represent various aspects and features of the present invention.

[0049] The utility model is designed as an adjustable bending dental floss stick, and the bending method of the adjustable bending dental floss stick is left-right bending. By bending the dental floss stick, the dental floss on the dental floss stick can be deformed, that is, the dental floss can be in a tight and loose state. The deformation of the dental floss can be applied to a variety of different tooth cleaning situations.

[0050] like Figure 1 As shown in Figure A, the utility model provides an adjustable bendable dental floss stick 100 with a V-shaped bendable portion, which comprises a dental floss holder 110, which comprises two side arms 111 and a connecting portion 112, wherein the two side arms 111 respectively comprise a first end away from the connecting portion 112 and a second end connected to the connecting portion 112, wherein a dental floss 113 is connected between the first ends, and wherein the second ends are respectively connected to the front half of the connecting portion 112; and a gripping and pressing portion 120, which comprises a front end connected to the connecting portion 112 and a rear end away from the connecting portion 112, wherein the front end is connected to the rear half of the connecting portion 112, and a bendable portion 121 is provided in the middle of the gripping and pressing portion 120, wherein the bendable portion 121 is a V-shaped groove, wherein the bendable portion 121 is used to bend the gripping and pressing portion 120 to the left and right sides, and drive the two side arms 111 to bend the dental floss 113 together.

[0051] In addition, first pressing members 122 are respectively designed on the left and right sides of the gripping and pressing part 120, so that the user can apply force from the first pressing members 122 to bend the left and right sides of the gripping and pressing part 120 connected to the first pressing members 122 to the left and right, that is, to bend the adjustable bending dental flosser 100 as a whole. Therefore, the design purpose of the first pressing member 122 is to provide a favorable force application position for the user to bend the dental flosser so as to bend the dental floss.

[0052] In addition, the design position of the first pressing member 122 can be designed on the outer side of the two side arms 111 in addition to any position on the left and right sides of the gripping and pressing portion 120. Therefore, the second pressing member can be connected to the outer side of one side of the two side arms 111 to provide a position for applying force. Since the design of the pressing member is to facilitate the user to apply force, the pressing member can be set at any position on the left and right sides of the adjustable bending dental floss stick itself.

[0053] Figure 1 B is Figure 1 A shows the bending state of the adjustable bendable dental flosser 100. When the user presses the first pressing member 122 to bend the adjustable bendable dental flosser 100, the left and right sides of the gripping pressing portion 120 will bend toward the bendable portion 121, and the two side arms 111 will also bend together. Therefore, the dental floss 113 connected to the two side arms 111 will change from a tight state to a loose state due to the bending. Depending on the different bending angles, the dental floss 113 will become a C-shape or a U-shape.

[0054] In addition, the present invention also provides a design of an adjustable bendable dental floss holder 200 having a U-shaped bendable portion, wherein the U-shaped bendable portion is a U-shaped groove, and the bottom of the groove and its left and right sides have respective bevel angles. Figure 2As shown in Figure A, the adjustable bendable dental floss stick 200 with a U-shaped groove has a dental floss holder 210, which has two side arms 211 and a connecting portion 212, wherein the two side arms 211 respectively have a first end away from the connecting portion 212 and a second end connected to the connecting portion 212, the first ends are connected to a dental floss 213, and the second ends are respectively connected to the front half of the connecting portion 212; and a gripping and pressing portion 220, which has a front end connected to the connecting portion 212 and a rear end away from the connecting portion 212, the front end is connected to the rear half of the connecting portion 212, and the middle of the gripping and pressing portion 220 has a bendable portion 221, the bendable portion 221 is a U-shaped groove, wherein the bendable portion 221 is used to bend the gripping and pressing portion 220 to the left and right sides, and drive the two side arms 211 to bend the dental floss 213 together. In addition, first pressing components 222 are respectively designed on the left and right sides of the gripping and pressing portion 220 , so as to provide a user with a pressing force from the first pressing components 222 .

[0055] like Figure 2 As shown in A, the bottom of the U-shaped groove and its left and right sides have respective bevel angles. The bevel angle between the bottom of the U-shaped groove and its left and right sides can be designed to be 10 degrees, so that the clamping angle between the left and right sides can reach 20 degrees. In this bent state, the dental floss can present the maximum bending similar to the U-shaped state, which is suitable for the use of small teeth and large curved surfaces. In addition, the bevel angle between the bottom of the U-shaped groove and its left and right sides can be designed to be 80 degrees, so that the clamping angle between the left and right sides can reach 160 degrees. In this state, the dental floss is slightly curved, which is suitable for the situation where the teeth are large and the curved surface is small.

[0056] Figure 3 and 4 The utility model discloses an improved design of the adjustable bending dental floss pick. Figure 3 The invention discloses an adjustable bendable dental floss stick 300 with a dental floss replacement function. The two side arms 310 on the dental floss holder in a U-shaped structure on the adjustable bendable dental floss stick 300 with a dental floss replacement function each have a through hole 311. The function of the through hole 311 is to allow the dental floss 320 to pass through and wrap around the through hole 311. After the dental floss 320 passes through the two through holes 311, one end of the dental floss 320 is wrapped around the first pressing member 331 of the holding and pressing part 330 of the bendable dental floss stick to be fixed. Through the design of the through hole and the pressing member of the bendable dental floss stick, the dental floss can be wrapped around these members to be fixed. At the same time, the dental floss can also be removed from the dental floss stick and replaced with a new one. Therefore, the dental floss becomes a movable design rather than a design that is integrally formed with the dental floss stick itself. The advantage of such a design is that the dental floss can be removed from the dental floss stick and new dental floss can be installed; therefore, the dental floss stick itself can be reused as long as the dental floss is replaced.

[0057] Figure 4 The invention relates to an adjustable bending dental floss stick 400 with double-sided grooves. Figure 2 Compared with the design of the adjustable bendable dental floss stick of A, the two sides of the gripping and pressing part 410 of the adjustable bendable dental floss stick 400 respectively have a bendable part 411, which is a U-shaped groove. Since the U-shaped groove is a bendable component, the design of the U-shaped grooves on both sides of the gripping and pressing part 410 allows the user to bend the adjustable bendable dental floss stick 400 on different sides through the U-shaped grooves. Therefore, the design that both sides of the adjustable bendable dental floss stick can be bent will facilitate users to use it more conveniently.

[0058] In addition, the present invention also has different improved designs for the gripping and pressing parts on the dental floss pick, such as Figures 5 to 7 shown. Figure 5 The invention is a dental floss pick with an adjustable bending structure and a first gripping and pressing part design. Figure 5 As shown, the adjustable bending dental flosser 500 has a dental floss holder 510, which has two side arms 511, a connecting portion 512 and dental floss 513; and a gripping and pressing portion 520. The connecting portion 512 is an arc-shaped structure, which is bent upward from the gripping and pressing portion 520 to the extending direction of the two side arms 511, so that the dental floss holder 510 is higher than the gripping and pressing portion 520. The design of making the horizontal height of the dental floss holder 510 higher than the gripping and pressing portion 520 is to make the gripping and pressing portion 520 close to or near the plane when the adjustable bending dental flosser 500 is placed on a plane, but the dental floss holder 510 will not have any contact with the plane; that is, the dental floss 513 on the dental floss holder 510 will not touch the plane, so as to keep the dental floss 513 clean and hygienic.

[0059] In addition, the central part of the gripping and pressing part 520 of the adjustable bending dental floss stick 500 is hollow, and the bendable part 521 is arranged at the front and rear ends of the gripping and pressing part 520. The bendable part 521 is used to provide the function of bending the adjustable bending dental floss stick 500. At the same time, the bottom surfaces of the front and rear ends of the gripping and pressing part 520 have protrusions 522, which are used to prop up the entire adjustable bending dental floss stick 500; the purpose is also to allow the protrusions 522 to contact the plane when the adjustable bending dental floss stick 500 is placed on the plane, and the dental floss holder 510 located on the protrusions 522 will not touch the plane, that is, the dental floss 513 will not touch the plane.

[0060] Figure 6 The invention is an adjustable bending dental floss pick with a second gripping and pressing part design. Figure 6As shown, the adjustable bending dental floss stick 600 has a dental floss holder 610, which has two side arms 611, a connecting portion 612 and dental floss 613; and a gripping and pressing portion 620. The connecting portion 612 is an arc-shaped structure, which is bent upward from the gripping and pressing portion 620 to the extending direction of the two side arms 611, so that the horizontal height of the dental floss holder 610 is higher than the gripping and pressing portion 620. The overall design of the adjustable bending dental floss stick 600 is also to prevent the dental floss 613 from contacting the plane when the adjustable bending dental floss stick 600 is placed on the plane. In addition, the central part of the gripping and pressing portion 620 of the adjustable bending dental floss stick 600 is hollow, and the bendable portion 621 is arranged at the front and rear ends of the gripping and pressing portion 620.

[0061] In addition, the gripping and pressing portion 620 is provided with an anti-slip portion 622, the function of which is to increase the friction area between the fingers, so that the user can easily hold and apply force to the adjustable bending dental flosser 600. Therefore, the anti-slip portion 622 is designed as a component with a concave-convex structure, so that when the user uses the adjustable bending dental flosser 600, it is not easy for the dental flosser to slip.

[0062] Figure 7 The invention is an adjustable bending dental floss pick with a third gripping and pressing part design. Figure 7 As shown, the central part of the gripping and pressing part 710 of the adjustable bending dental floss pick 700 is hollow, and the two outer sides of the hollow part are elliptical to increase the contact area with the user's fingers. In addition, the outer side is also designed with a non-slip part 711, so that the user can easily hold and apply force to the adjustable bending dental floss pick 700. In addition, the bendable part 712 is set at the front and rear ends of the gripping and pressing part 710.

[0063] In addition, the design of the gripping and pressing part of the utility model can be regarded as an independent component of the left and right halves. Therefore, the bendable part can be used as a connecting component between the left and right halves of the gripping and pressing part, and provide a bending function. Therefore, in the above-mentioned various designs of adjustable bending dental floss picks, the bendable part is designed as a bendable component, and its shape can be a groove, or a connecting component for connecting the left and right halves of the gripping and pressing part.

[0064] The adjustable bending dental floss stick of the present invention was also subjected to three tests to prove its effectiveness in cleaning the tooth surface and the gaps between teeth, its safety in protecting the gums, and its convenience in use from the perspective of ergonomics.

[0065] The first test is a dental floss tensile test on dental floss sticks based on the latest version of the international standard ISO 28158:2018. According to the international standard, dental floss should be able to withstand a tensile force of 10N (approximately equal to 1kgf) and should not break at either end. The utility model uses 15 samples of adjustable bending dental floss sticks in a taut state and 15 samples of adjustable bending dental floss sticks in a bent state for testing. After being tested with a calibrated tensile testing machine, the results can meet the international standard requirement of 10N for 10 seconds. Another 10 adjustable bending dental floss stick samples were subjected to destructive testing, and the results showed that a tensile force greater than 300N (approximately 3.0kgf) would cause the dental floss to fall off the dental floss stick, which is three times more than the international standard requirement.

[0066] The second test was a teeth cleaning test, where toothpaste was applied to a tooth model to simulate dirt. 15 testers were used in each test to perform a simulated teeth cleaning test, in which the adjustable bendable dental floss stick was inserted into the gaps between teeth of the tooth model when the dental floss was tight and in a bent state, and the coated toothpaste was scraped off. Commercially available Oral-B and 3M dental floss sticks were selected as the control group. The results showed that the teeth cleaning efficiency of the adjustable bendable dental floss stick when the dental floss was bent was 46.47%, and the teeth cleaning efficiency of the adjustable bendable dental floss stick when it was tight was 31.27%, which was significantly higher than the 27.53% of the Oral-B dental floss stick in the control group and the 21.13% of the 3M dental floss stick. The results show that the teeth cleaning efficiency of the adjustable bending dental floss stick in a bent state is higher than that of the adjustable bending dental floss stick when the dental floss is in a tight state, which further proves that the dental floss stick should be designed so that the dental floss can be in a bent state in order to achieve better teeth cleaning efficiency.

[0067] The third test cited the international medical device standard IEC 62366-1:2015 to conduct a human factors engineering test on the user of the adjustable bendable dental floss stick. This test designed a questionnaire based on the method of the international standard, and users filled in the scores based on their true feelings to obtain real-world data as product feedback. When scoring, special attention was paid to the convenience of use, teeth cleaning effect and protection of gums. The results showed that users could accept the adjustable bendable dental floss stick, and the average score was higher than that of the control group. This clinical-like human factors engineering test proved that the adjustable bendable dental floss stick has the advantages of ease of use, teeth cleaning efficacy and gum protection safety over ordinary dental floss stick products.

[0068] Therefore, the main feature of the adjustable bendable dental flosser of the present invention is the design of the bendable portion in the middle of the gripping and pressing portion. The function of the bendable portion is to allow the adjustable bendable dental flosser to bend left and right, and then bend the dental floss so that the dental floss can have different tightness states for users to use for cleaning teeth.
