Background technique

At present, in the past 20 to 30 years, with the vigorous development of the economy in all countries in the world, most people living in metropolitan areas have escaped from the poverty of living materials, and their food, clothing, housing and transportation are extremely affluent, convenient and comfortable. In a comfortable modern life, people not only gradually pay attention to the enjoyment of food, but also pay attention to the health of their oral cavity. However, it is fermented and corrupted in the oral cavity, thereby breeding bacteria, causing peculiar smell in the oral cavity, forming plaque on the tooth surface or causing tooth decay. People often choose to use toothpicks, interdental brushes, Dental cleaning products such as dental floss or dental floss sticks are used to clean the surface and gaps of the teeth; in order to meet this vast and urgent need, various cleaning products made of different materials and in different shapes have emerged as the times require. It provides consumers with a wide variety of choices, and is expected to be favored by consumers, so that consumers can effectively remove food residue, tartar or plaque on the tooth surface or between the teeth, ensuring that consumers Oral cleaning and sanitation, thereby obtaining business opportunities for those skilled in the art, and can therefore obtain due profits.

Now take a traditional dental floss stick 10 as an example, as follows, please refer to FIG. 101 is U-shaped, and its two corresponding ends are fixedly connected to the two ends of a dental floss 103 respectively, and the holding body 102 is fixedly connected to the dental floss fixing body 101 for the user to hold; thus, the user can After a meal, grasp the holding body 102 of the traditional dental floss stick 10 with two fingers (such as the thumb and forefinger), and place the dental floss fixing body 101 into the oral cavity, so that the dental floss can be used The floss 103 on the main body 101 is fixed to scrape off tartar or food residues on the surface of the teeth and in the gaps between the teeth.

Although, referring to Fig. 1 again, the dental floss 103 on the traditional dental floss stick 10 can be used by the user to remove food residues and tartar on the surface of the teeth and between the teeth, although the dental floss 103 is in the traditional The dental floss stick 10 is in a tight straight line, but the user must first apply pressure to the dental floss fixing body 101 so that the dental floss 103 can be inserted into the gap between the teeth, and then the traditional dental floss can be moved back and forth. stick 10, and use the dental floss 103 to remove food residue and tartar between the teeth, however, the dental floss 103 is not easy to enter the tooth gap because the tooth gap is too small, or the dental floss fixing body 101 is deformed to cause the dental floss When the thread 103 is no longer in a tight straight line, the food residue and tartar between the teeth and/or the gaps near the gums are not easy to be removed. Therefore, in order to make the dental floss 103 stretch into the gaps Most users often apply too much force to the traditional dental floss pick 10, causing the floss fixing body 101 to twist and deform, and the tight and tough dental floss 103 or the hard dental floss fixing body 101 Rubbing or colliding with the user's gums and gingival papilla, thereby causing problems such as bleeding of the gums and gingival papilla, and bacterial infection.

In view of this, referring to Fig. 2, those skilled in the art have designed and manufactured a prior art interdental brush 11, the prior art interdental brush 11 consists of a supporting body 110 and an elastic bristle body 113, wherein, the support body 110 is made of a first plasticized material, on which a handle 111 is formed near one end, the handle 111 is flat, so that the user can use two Fingers (eg thumb and forefinger) hold it, and the other end thereof extends linearly away from the handle 111 to form a bristle support portion 112 , which is in the shape of a slender rod.

On the interdental brush 11 of the prior art, referring again to Fig. 2, the elastic bristle body 113 is made of a second plasticized material, and is covered on the bristle support portion 112 adjacent to its free end 112f and form a plurality of bristles 1130 vertically on the surface; because, on the interdental brush 11 of the prior art, the hardness of the first plasticized material is much greater than that of the second plasticized material Therefore, the supporting body 110 of the interdental brush 11 of the prior art not only has sufficient structural strength, can be held and applied by the user, and can simultaneously support the elastic bristle body 113 and the bristle body 113 on it. The bristles 1130 not only have sufficient structural strength, but also have sufficient softness. After the elastic bristle body 113 and the bristles 1130 on it are successfully inserted into the gap between the teeth of the user, By moving the prior art interdental brush 11 back and forth, the bristles 1130 can be used to easily brush away the food residue and tartar between the user's teeth. Generally speaking, since the gap between the user's teeth near the gums is relatively large, when the user encounters a situation where the gap between the teeth is too small, he can hold the handle 111 of the interdental brush 11 of the prior art , put the free end 112f of the prior art interdental brush 11 into the oral cavity of the user, and after aligning the tooth gaps adjacent to the gums, they can pass through the tooth gaps one by one to pass the elastic bristles The body 113 and the bristles 1130 on it can easily brush away the food residues and tartar remaining in the gaps of the teeth, and bring them out of the gaps of the teeth for removal. At the same time, the soft and elastic elastic bristle body 113 and the bristles 1130 on it can also be used to reciprocate and massage the gums corresponding to the gaps between the teeth. In this way, not only can the remaining food residues and tartar in the gaps of the teeth adjacent to the gums be completely removed under the premise of effectively avoiding the bleeding of the gums, but also the gums can be massaged back and forth to effectively promote the healing process of the gums. blood circulation, so as to achieve the dual-effect health care purpose of maintaining the health of teeth and gums.

Although the above-mentioned traditional dental floss stick 10 and the interdental brush 11 of the prior art have specific supporters based on their characteristics and functions, but for a large number of carnivorous or vegetarian groups, due to the aforementioned Both the traditional dental floss stick 10 and the interdental brush 11 of the prior art cannot provide a mechanism for the user to easily remove the animal or vegetable fibers firmly embedded between the teeth, so the carnivorous or vegetarian groups still tend to use The traditional bamboo "toothpick" utilizes the sharp shape and tough material characteristics of the bamboo "toothpick", so that its tip can easily pass through the gap between the user's teeth (or interdental gap, interdental gap), and accurately And it is indeed effective to remove and clean the animal or plant fiber firmly embedded in the gap between the teeth, but unfortunately, the average person will unconsciously use the bamboo "toothpick" in the process of Forcibly press the shaft portion adjacent to the tip of the bamboo "toothpick" into the interdental papilla area, thereby forming a gap that does not exist in each interdental papilla area. Under the circumstances, the above-mentioned gap will naturally become larger and larger, which will lead to the problem that the gap between the teeth will become larger and larger. Even, often when the user applies improper force when flossing teeth, because the bamboo The sharp shape and tough material of the front end of the "toothpick" can damage the enamel on the tooth surface, gum papilla or puncture the soft tissue of the gums, causing bleeding of the gums, and then causing local bacterial infections. This is also strongly urged by most dentists. The main reason why its patients should not use bamboo "toothpicks", and it is strongly recommended to their patients that no matter what kind of material the "toothpicks" are used, in addition to the use of gentle force, the "toothpicks" are only It is more suitable for users who have experienced gingival papilla recession and enlarged interdental spaces.

As mentioned above, in view of the love and special needs of specific ethnic groups for "toothpicks", a special toothpick brush 1 structure has been developed and designed in this field. Please refer to Figures 3 and 4. The toothpick brush 1 is made of fiber The hard plasticized material is integrally molded, including a handle section 12, a cleaning section 13, a bristle section 15 and a toothpick section 17, wherein two corresponding sides of the handle section 12 are respectively recessed with a Gripping groove 121, when the user holds the handle segment 12 with two fingers (such as: thumb and forefinger), part of the skin of the user's fingers will sink into the gripping groove 121, to increase the grip of the fingers. The frictional force of holding the toothpick brush 1 enables the user to firmly hold the handle section 12 when using the toothpick brush 1 to clean teeth, so as to apply force to the toothpick brush 1 stably and accurately, thereby avoiding the use of Inconvenience caused by slippage of the user's fingers from the handle section 12, and even prevents the user from causing gum nipples and gums to be injured and bleeding due to improper application of force to the toothpick brush 1 due to the slippage of the fingers .

Referring back to Fig. 3 and shown in Fig. 4, on the toothpick brush 1, one end of the cleaning section 13 is connected with one end of the handle section 12, and the width of the cleaning section 13 is gradually from one end to the other end. Reduced to become a cone, so that the other end of the cleaning section 13 is easier to extend into the gap between the adjacent teeth, so as to push out the food residue and tartar remaining between the teeth . In addition, a plurality of first scraping units 131 are respectively arranged on two corresponding side surfaces of the cleaning section 13. When the cleaning section 13 extends into the gap between the teeth and moves back and forth, the first scraping units 131 That is, it can scrape off the food residue, tartar and dental plaque between the teeth on the teeth, so as to achieve the effect of effectively cleaning the teeth. Again, please refer to Fig. 3 and Fig. 4, on the toothpick brush 1, the The first scraping unit 131 can be made into a concave shape or other shapes, such as bumps, waves, etc., according to production or market requirements.

Furthermore, referring to Fig. 3 and shown in Fig. 4, the bristle section 15 includes a rod body 151 and a plurality of bristles 153, wherein one end of the rod body 151 is connected with the other end of the cleaning section 13, and the toothpick brush 1, the diameter of the rod body 151 gradually decreases from one end to the other end, and the minimum diameter of the rod body 151 is preferably 0.35-0.45 millimeters (mm), and the maximum diameter of the rod body 151 is preferably 0.55-0.65 mm. Preferably, in this way, when the user uses the bristle segment 15 to clean the teeth, the other end of the rod body 151 can be easily inserted into the gap between the teeth, and after the other end of the cleaning segment 13 is inserted into the gap between the teeth, the The first scraping unit 131 produces an effect of effectively cleaning teeth.

3 and 4, the bristles 153 are arranged at two corresponding side edges of the rod body 151 at intervals, and the length of the bristles 153 is from the middle region of the rod body 151 to the two ends of the rod body 151. Gradually shrink, so that food residues and tartar can be brought out from between the teeth through multiple rows of bristles 153 and their length changes, wherein the distance between the bristles 153 on the same side is preferably 0.4-0.6 millimeters apart , and the length of the longest bristle 153A is preferably 1.4-1.8 mm, and the length of the shortest bristle 153B is preferably 0.5-0.7 mm. In addition, the number of the bristles 153 on the same side is preferably 8-10 better.

Referring again to Figures 3 and 4, one end of the toothpick segment 17 is connected to the other end of the handle segment 12, and the width of the toothpick segment 17 gradually decreases from one end to the other end to form a knife-shaped (As shown in Figure 3 ), again, a plurality of second scraping units 171 are respectively arranged on the two corresponding sides of the toothpick section 17, so that when the toothpick section 17 stretches into the gap between the teeth, the second scraping unit The removal unit 171 can scrape off the food residue, tartar and dental plaque between the teeth on the teeth, and then achieve the effect of cleaning the teeth and the teeth. Again, on the toothpick brush 1, the second scraping unit 171 It can also be made into dimples or other shapes according to production or market demand, such as bumps, waves, etc., and the thickness of the thinnest part of the toothpick segment 17 is preferably 0.3-0.4 mm The thickness of the thickest part of the toothpick section 17 is preferably 0.55 to 0.65 millimeters, so that the other end of the toothpick section 17 can be easily inserted into the gap between the teeth, and the second scraping can be achieved by changing the thickness. The unit 171 can be attached to the periphery of the teeth to effectively remove tartar and plaque on the surface of the teeth. In addition, in order to make the toothpick section 17 not only clean the interdental spaces, but also scrape off the tongue coating on the tongue surface, the toothpick section 17 can be shaped like a knife with a wider area.

In summary, because the toothpick brush 1 has structural features such as the cleaning section 13, the bristle section 15 and the toothpick section 17, in theory, it seems to be able to have both "the toothpick of the prior art" and "the toothpick of the prior art". The effect of "interdental brush", so that users can choose to use the appropriate cleaning section 13, bristle section 15 or toothpick section 17 to clean teeth and interdental spaces according to their own needs, and can use the scraping unit 131, 171 The unique design scrapes off the residue, tartar and plaque on the teeth between the teeth, and has better practicability. Yet when the user actually uses this toothpick brush 1, because its whole body is made by the rigid plasticized material that contains fiber, therefore, its function and effect are still no difference with traditional bamboo " toothpick ", still It is very easy to form gaps that did not exist in the interdental papilla area during use. Therefore, as a result of long-term use of the toothpick brush 1, it is inevitable that the aforementioned gaps will naturally become larger and larger, resulting in gaps between teeth. The problem that becomes bigger and bigger, even, often can make the user very easily when flicking teeth because of the improper application of force , and hurt the gingival papilla or puncture the soft tissue of the gums, causing bleeding of the gums or gingival papilla, and then causing local bacterial infection. In addition, no matter the toothpick brush 1, the aforementioned traditional dental floss stick 10 or the aforementioned interdental brush 11 of the prior art are used, for the teeth (such as: molars) located in the rear of the oral cavity, the user must open his mouth wide , and press the corner of the mouth vigorously with the toothpick brush 1, the aforementioned traditional dental floss stick 10 or the aforementioned interdental brush 11 of the prior art, so that the bristle section 15 or the dental floss 103 on the aforementioned traditional dental floss stick 10 and the aforementioned The bristles 1130 on the interdental brush 11 of the prior art extend into the interdental spaces of the rear teeth, which not only causes great inconvenience to the user in use, but also is extremely unsightly. Brush 1, the above-mentioned traditional dental floss stick 10 and the above-mentioned interdental brush 11 of the prior art are comprehensively improved, so that they are not only more convenient and beautiful in use, but also can effectively protect the tooth surface and gingival papilla of the user. Under the premise of protecting the gums, providing users with a variety of options such as toothpicks, interdental brushes, and dental floss sticks has become an important issue that the industry is eager to develop and improve, and it is also an important issue that the utility model wants to discuss here. topic.
