Description

牙刷 toothbrush 發明領域 Field of invention

本發明係有關於一種牙刷。 The invention relates to a toothbrush.

本專利申請係根據2011年12月7日在日本所申請之特願2011-267939號來主張優先權,並將其內容引用至此。 Priority is claimed on Japanese Patent Application No. 2011-267939, the entire disclosure of which is hereby incorporated by reference.

發明背景 Background of the invention

一般牙刷係具有:手柄體,係具有設植有毛束之頭部、使用時可握持之手柄部、及將頭部與手柄部連接之頸部;植毛部,係在頭部之植毛面設植用毛的毛束。 The general toothbrush has a handle body having a head with a hair bundle, a handle portion that can be gripped during use, and a neck portion that connects the head portion and the handle portion; the hair-planting portion is attached to the hair-planting surface of the head. Set the hair bundles for planting hair.

在為口腔內清掃器具之牙刷中,為了提高最必要之功能的清掃效果,於是產生了各種之發明。為了提高清掃效果,重要的是使植毛部與清掃對象部位接觸,將清掃對象部位用適當之刷掃壓力來擦掃。當植毛部未與清掃對象部位適當地接觸時,就無法將牙面、臼歯之咬合面、牙間、與牙頸部等所附著之牙垢充分地除去。又,清掃口腔內時,當刷掃壓力過小時,就難以將牙垢,特別是牙間部或與牙頸部等之狹小部之牙垢除掉,當刷掃壓力過大時,就有弄傷牙齦或牙齒之虞。 In the toothbrush which is an in-oral cleaning device, in order to improve the cleaning effect of the most necessary function, various inventions have been produced. In order to improve the cleaning effect, it is important to bring the hair-planting part into contact with the cleaning target portion, and to clean the target portion with appropriate brushing pressure. When the hair-planting portion is not properly brought into contact with the cleaning target portion, the tartar attached to the tooth surface, the occlusal surface of the jaw, the interdental space, and the tooth neck portion cannot be sufficiently removed. Moreover, when cleaning the oral cavity, when the brushing pressure is too small, it is difficult to remove the tartar, especially the dent of the interdental part or the narrow part of the tooth neck, and when the brushing pressure is too large, the gums are damaged. Or the top of the teeth.

對於牙刷,一般而言,對於毛束之配置、用毛之 形狀、毛束之裁切形狀等會盡心處理而使植毛部可與清掃對象部位適當地接觸。 For the toothbrush, in general, for the configuration of the hair bundle, the use of hair The shape, the cutting shape of the tuft, and the like are handled with care, so that the tufting portion can be properly brought into contact with the cleaning target portion.

近年,根據衛生考量之提高,對於牙刷,尋求更高一層之清掃效果的提升,針對上述希望,提案有將不同直徑之毛束組合之牙刷、或將不同毛長之毛束組合之牙刷。 In recent years, according to the improvement of hygiene considerations, for the toothbrush, the improvement of the cleaning effect of the higher layer has been sought. In view of the above hopes, there are proposed toothbrushes which combine hair bundles of different diameters or toothbrushes which combine hair bundles of different hair lengths.

又,根據手柄體之盡心處理,而出現了提高清掃效果之測試。 Moreover, according to the careful handling of the handle body, a test for improving the cleaning effect has appeared.

例如,提案有一刷毛,而該刷毛係橫跨牙刷首頸部之整體,使刷毛部之植毛方向的厚度相對於另一方,為數值較小之整個長方形或楕圓形(例如,專利文獻1)。根據專利文獻1之發明,使首部變細而使其具彈性地彎曲,藉此尋求緩和刷掃壓力。 For example, it is proposed to have a bristles that span the entirety of the head and neck of the toothbrush so that the thickness of the bristle portion in the direction of the hair-planting portion is smaller than the other, and the entire rectangle or the circle is smaller (for example, Patent Document 1) . According to the invention of Patent Document 1, the head portion is made thinner and elastically bent, thereby seeking to alleviate the brushing pressure.

或者是,提案有一牙刷,其係使碰觸掌握部之大拇指的最粗部分輪廓為特定形狀之六角形狀(例如,專利文獻2)。根據專利文獻2之發明,藉由改變握著之手的大拇指所碰觸之前述六角形狀的面,來決定牙與牙齦之邊界或牙面與牙刷之毛尖端而成之角度,尋求効率良好地清掃口腔內。 Alternatively, a toothbrush having a hexagonal shape of a specific shape in which the thumb of the grip portion is touched is proposed (for example, Patent Document 2). According to the invention of Patent Document 2, the angle between the teeth and the gums or the angle between the tooth surface and the tip of the toothbrush is determined by changing the surface of the hexagonal shape touched by the thumb of the hand, and the efficiency is sought. Clean the mouth.

發明概要 Summary of invention

然而,對於臼歯之牙面、咬合面、牙間部、與牙 頸部等所有清掃對象部位,要使植毛部適當地接觸,可使頸部變細,就能有效提高在口腔內之操作性。 However, for the tooth surface, occlusal surface, interdental part, and teeth All the parts to be cleaned, such as the neck, should be made to make the hair part properly contact, so that the neck can be thinned, and the operability in the oral cavity can be effectively improved.

但,當單純欲使頸部變細且將口腔內之牙刷的操作性提高,手柄體之強度就會不足,頸部之彎曲量變得過大,清掃效果容易降低。藉由使用高強度(彎曲彈性率2000MPa以上)之樹脂來將手柄體成形,雖可防止手柄體折斷或破損,但無法控制頸部之彎曲量,會有無法用適當之刷掃壓力來將清掃對象部位擦掃的問題。 However, when the neck is made thinner and the operability of the toothbrush in the oral cavity is simply increased, the strength of the handle body is insufficient, the amount of bending of the neck becomes excessive, and the cleaning effect is easily lowered. By using a high-strength (bending elastic modulus of 2000 MPa or more) resin to shape the handle body, it is possible to prevent the handle body from being broken or broken, but it is impossible to control the amount of bending of the neck, and it is impossible to clean with a proper brushing pressure. The problem of rubbing the object part.

因此,本發明之目的在於提供一種即使使頸部變細,清掃效果亦相當高之牙刷。 Accordingly, it is an object of the present invention to provide a toothbrush which has a relatively high cleaning effect even if the neck is made thinner.

本發明者們所認真討論之結果而言,本發明所達成之目標,其係隨著將頸部之截面輪廓從頭部側朝向手柄部側,使其變化成特定形狀,並藉由將頸部之彎曲方向階段性限制,使植毛部與清掃對象部位適當地接觸,並用適當之刷掃壓力來清掃,而可提高清掃效果。 As a result of earnest discussion by the inventors, the object of the present invention is to change the shape of the neck from the head side toward the handle side to a specific shape, and by neck The bending direction is stepwise restricted, so that the hair-planting portion and the cleaning target portion are properly contacted, and the appropriate brushing pressure is used for cleaning, thereby improving the cleaning effect.

即,本發明之牙刷之一態樣,係具有設植有毛束之頭部、延伸設置於前述頭部之頸部、及延伸設置於前述頸部之手柄部,且前述頸部隨著從前述頭部側朝向前述手柄部側,截面輪廓會變化者,其特徵在於:前述頸部,係使前述頭部側之截面輪廓為大致圓形,且隨著前述大致圓形的截面輪廓朝向述手柄部側,會成為用表面、背面及側面形成各邊之大致四角形的截面輪廓,進而隨著前述大致四角形之截面輪廓朝向前述手柄部側,成為頂部位於兩側 面且在厚度方向扁平之大致多角形。 That is, in one aspect of the toothbrush of the present invention, there is a head having a hair bundle, a neck extending from the head, and a handle extending from the neck, and the neck is When the head side faces the handle portion side and the cross-sectional profile is changed, the neck portion has a substantially circular cross-sectional profile on the head side, and the substantially circular cross-sectional profile is oriented toward the head. The handle portion side has a substantially quadrangular cross-sectional profile in which the sides, the back surface, and the side surfaces are formed, and the cross-sectional contour of the substantially quadrangular shape faces the handle portion side, and the top portion is located on both sides. The surface is substantially polygonal in shape in the thickness direction.

在前述厚度方向扁平之大致多角形,宜任意一邊由前述頸部之表面形成,與前述任意一邊相對向之邊則由前述頸部之背面形成。 Preferably, the substantially polygonal shape which is flat in the thickness direction is formed by the surface of the neck portion, and the side opposite to the one side is formed by the back surface of the neck portion.

即,本發明係關於以下所述。 That is, the present invention relates to the following.

(1)一種牙刷,係具有設植有毛束之頭部、延伸設置於前述頭部之頸部、及延伸設置於前述頸部之手柄部,且前述頸部隨著從前述頭部側朝向前述手柄部側,截面輪廓會變化者,其特徵在於:前述頸部,係使前述頭部側之截面輪廓為大致圓形,且隨著前述大致圓形的截面輪廓朝向述手柄部側,會成為用表面、背面及側面形成各邊之大致四角形的截面輪廓,進而隨著前述大致四角形之截面輪廓朝向前述手柄部側,成為頂部位於兩側面且在厚度方向扁平之大致多角形。 (1) A toothbrush having a head having a hair bundle, a neck portion extending from the head portion, and a handle portion extending from the neck portion, wherein the neck portion faces from the head side In the case of the handle portion side, the cross-sectional profile is changed, wherein the neck portion has a substantially circular cross-sectional profile on the head side, and the substantially circular cross-sectional profile faces the handle portion side. The cross-sectional contour of the substantially square shape in which each side is formed by the front surface, the back surface, and the side surface is further formed into a substantially polygonal shape in which the top portion is located on both side surfaces and is flat in the thickness direction as the cross-sectional contour of the substantially square shape faces the handle portion side.

較佳實施例之詳細說明 Detailed description of the preferred embodiment

針對本發明之一實施形態之牙刷,在以下參照圖1~2來說明。 A toothbrush according to an embodiment of the present invention will be described below with reference to Figs.

圖1A與圖1B之牙刷1具有:在俯視下大致四角形之頭部2、延伸設置於前述頭部2之頸部4、與延伸設置於前述頸部4之手柄部6所一體成形之大致長條狀的手柄體10、以及 設於頭部2之植毛部(不圖示)。 The toothbrush 1 of Fig. 1A and Fig. 1B has a head portion 2 having a substantially square shape in plan view, a neck portion 4 extending from the head portion 2, and a substantially long shape integrally formed with the handle portion 6 extending from the neck portion 4. a strip of handle body 10, and The hair-planting part (not shown) provided in the head 2.

手柄體10之材質係可考慮手柄體10所求之剛性或機械特性等來決定,例如,宜為彎曲彈性率(JISK 7203)500MPa以上之樹脂(以下,稱為硬質樹脂),更宜為彎曲彈性率2000MPa以上之樹脂。使用於手柄體10之樹脂之彎曲彈性率的上限無特別地限定,例如可為3000MPa。 The material of the handle body 10 can be determined in consideration of the rigidity or mechanical properties of the handle body 10, and is preferably a resin having a bending elastic modulus (JISK 7203) of 500 MPa or more (hereinafter referred to as a hard resin), and is preferably curved. A resin having an elastic modulus of 2000 MPa or more. The upper limit of the bending elastic modulus of the resin used for the handle body 10 is not particularly limited, and may be, for example, 3000 MPa.

作為彎曲彈性率500MPa以上之樹脂,例如可舉例有聚丙烯(PP)、聚對苯二甲酸乙二酯(PET)、聚丁烯對苯二甲酸酯樹脂(PBT)、聚對苯二甲酸環已烷二甲酯(PCT)、聚縮醛(POM)、萘二甲酸乙二酯(PEN)、聚苯乙烯(PS)、丙烯腈-丁二烯-苯乙烯共聚物樹脂(ABS)、丙酸纖維素(CP)、聚芳基酸酯、聚碳酸酯、丙烯腈-苯乙烯共聚物聚脂(AS)等,當中宜為彎曲彈性率2000MPa以上之POM、PEN、PBT等。藉由使用彎曲彈性率2000MPa以上之樹脂,可使頭部2變薄,使頸部4變細,來提高在口腔內之操作性,且防止手柄體10之破損。 Examples of the resin having a bending modulus of 500 MPa or more include polypropylene (PP), polyethylene terephthalate (PET), polybutylene terephthalate resin (PBT), and poly (terephthalic acid). Cyclohexane dimethyl ester (PCT), polyacetal (POM), ethylene naphthalate (PEN), polystyrene (PS), acrylonitrile-butadiene-styrene copolymer resin (ABS), Cellulose propionate (CP), polyarylate, polycarbonate, acrylonitrile-styrene copolymer polyester (AS), etc., preferably POM, PEN, PBT, etc. having a flexural modulus of 2000 MPa or more. By using a resin having a bending modulus of 2000 MPa or more, the head portion 2 can be made thinner, the neck portion 4 can be made thinner, the operability in the oral cavity can be improved, and the handle body 10 can be prevented from being damaged.

又,手柄體10可用軟質樹脂被覆手柄部6之一部分或是全部。藉由用軟質樹脂被覆手柄部6之一部分或是全部,使用者握住手柄部6時之手的合適感會提升,又可防止握持之手指滑開。 Further, the handle body 10 may be covered with a part or all of the handle portion 6 with a soft resin. By covering one or both of the handle portions 6 with a soft resin, the user's proper feel when holding the handle portion 6 is improved, and the gripping fingers are prevented from slipping open.

作為軟質樹脂,例如,宜為硬度SHORE A90以下之樹脂,更宜為硬度SHORE A10~40之樹脂可供舉例。作為上述軟質樹脂,例如,聚烯系彈性體、苯乙烯系彈性體、聚酯系彈性體、聚氨酯系熱可塑性彈性體等之彈性體樹脂、矽 等可供舉例。 As the soft resin, for example, a resin having a hardness of SHORE A90 or less is preferable, and a resin having a hardness of SHORE A10 to 40 is more preferably exemplified. As the soft resin, for example, an elastomer resin such as a polyolefin elastomer, a styrene elastomer, a polyester elastomer, or a polyurethane thermoplastic elastomer, or the like, Etc.

手柄體10之長度L1係可關於操作性等來決定,例如,可為150~200mm。 The length L1 of the handle body 10 can be determined with respect to operability and the like, and can be, for example, 150 to 200 mm.

頭部2係將手柄體10之長度方向作為長邊,並使在俯視下頸部4側之頂部為用曲線所切除角落之大致四角形的平板狀,且一方之面(植毛面)20複數形成有植毛穴22者。該植毛穴22設植有束好用毛之毛束,形成複數毛束構成之植毛部。 In the head portion 2, the longitudinal direction of the handle body 10 is defined as a long side, and the top portion of the neck portion 4 in plan view is a substantially square-shaped flat plate having a corner cut by a curved line, and one surface (planting surface) 20 is formed in plural. There are 22 hairy points. The planting hole 22 is planted with bundles of hairs that are used to form a hairy part composed of a plurality of hair bundles.

在本稿中,將與植毛面20且與手柄體10之長度方向正交之方向當作寬度,將與植毛面20正交之方向當作厚度。此外,將植毛面20所面對之側當作表面,將植毛面20面對之側的相反側當作背面。 In the present draft, a direction orthogonal to the hair-growing surface 20 and the longitudinal direction of the handle body 10 is regarded as a width, and a direction orthogonal to the hair-growing surface 20 is regarded as a thickness. Further, the side on which the hair-growing surface 20 faces is regarded as a surface, and the side opposite to the side on which the hair-planting surface 20 faces is regarded as a back surface.

頭部2之大小可考慮在口腔內之操作性等來決定。 The size of the head 2 can be determined in consideration of the operability in the oral cavity and the like.

頭部2之寬度W1,當過大時在口腔內之操作性會降低,當過小時,植毛之毛束之數量會過度減少,容易損及清掃效果。故,寬度W1,例如可為5~13mm。 The width W1 of the head 2 is less operability in the oral cavity when it is too large, and when it is too small, the number of hair bundles of the hair is excessively reduced, which easily impairs the cleaning effect. Therefore, the width W1 can be, for example, 5 to 13 mm.

頭部2之厚度T1係愈薄愈能提高在口腔內之操作性,但當過薄時,頭部2之強度容易變得不足。故,厚度T1可考慮手柄體10之材質等來決定,例如,宜為1.5~5mm,更宜為2~3mm。 The thinner the thickness T1 of the head 2 is, the more the operability in the oral cavity can be improved, but when it is too thin, the strength of the head 2 tends to become insufficient. Therefore, the thickness T1 can be determined in consideration of the material of the handle body 10, for example, it is preferably 1.5 to 5 mm, more preferably 2 to 3 mm.

頭部2之長度L3,當過長時容易損及在口腔內之操作性,當過短時,植毛之毛束之數量變得過少,容易損及清掃效果。故,長度L3可在10~26mm之範圍來適宜地決定。 The length L3 of the head 2 is likely to impair the operability in the oral cavity when it is too long, and when it is too short, the number of hair bundles of the hairs is too small, and the cleaning effect is easily damaged. Therefore, the length L3 can be appropriately determined in the range of 10 to 26 mm.

植毛穴22之形狀並無特別地限定,可舉例有正圓 或楕圓等之圓形、三角形或四角形等之多角形等。 The shape of the planting hole 22 is not particularly limited, and examples thereof include a perfect circle. Or a polygon such as a circle, a triangle, or a quadrangle such as a circle.

植毛穴22之數量無特別限定,例如可為10~60。 The number of the planting holes 22 is not particularly limited and may be, for example, 10 to 60.

植毛穴22之直徑根據尋求之毛束的粗度來決定,例如可為1~3mm。 The diameter of the planting hole 22 is determined according to the thickness of the sought-up tuft, and may be, for example, 1 to 3 mm.

植毛穴22之配列樣式並無特別限定,所謂的棋盤格狀或千鳥紋狀等,可為任一配置樣式。 The arrangement pattern of the planting hair hole 22 is not particularly limited, and the so-called checkerboard pattern or the thousand bird pattern may be in any arrangement pattern.

作為構成毛束之用毛,可舉例有朝向毛前端而其直徑逐漸變小之用毛(漸縮毛)、除了毛前端之磨圓部,外徑約略相同之用毛(直毛)。 Examples of the hair constituting the hair bundle include a hair (a tapered hair) whose diameter gradually decreases toward the front end of the hair, and a hair (straight hair) having an outer diameter which is approximately the same except for the rounded portion of the front end of the hair.

用毛之材質可使用,例如,6-12尼龍、6-10尼龍等之聚醯胺、PET、PBT、聚對苯二甲酸二丙酯(PTT)、PEN、聚萘二酸丁醇酯(PBN)等之聚脂、PP等之聚烯、烯烴系彈性體、苯乙烯系彈性體等之合成樹脂材料。這些樹脂材料可以單獨1種來使用,亦可組合2種以上來使用。 The material of the hair can be used, for example, 6-12 nylon, 6-10 nylon, etc., polyamide, PET, PBT, polybutylene terephthalate (PTT), PEN, polybutylene naphthalate ( A synthetic resin material such as a polyester such as PBN), a polyolefin such as PP, an olefin elastomer, or a styrene elastomer. These resin materials may be used alone or in combination of two or more.

又,用毛可為多重芯構造,而該多重芯構造具有芯部與設於前述芯部之外側之至少1層以上之鞘部。 Further, the hair may have a multi-core structure having a core portion and at least one or more sheath portions provided on the outer side of the core portion.

用毛之截面輪廓並無特別限定,例如,可舉例有正圓形、楕圓形等之圓形、三角形、四角形、五角形、六角形等之多角形、星形、三葉之幸運草形、四葉之幸運草形等。 The cross-sectional profile of the hair is not particularly limited, and examples thereof include a circular shape, a triangular shape, a square shape, a hexagonal shape, a polygonal shape, a star shape, and a three-leaf lucky grass shape. Four leaves of lucky grass and so on.

用毛之粗度並無特別限定,截面輪廓為圓形時,例如,可為3~11mil(1mil=1/1000 inch=0.025mm)。毛束可用所有為相同粗度之用毛來構成,亦可組合2種以上之不同粗度之用毛。 The thickness of the hair is not particularly limited, and when the cross-sectional profile is circular, for example, it may be 3 to 11 mils (1 mil = 1/1000 inch = 0.025 mm). The tufts may be composed of all the hairs of the same thickness, and may be combined with two or more different thicknesses.

用毛之長度並無特別限定,例如可為6~12mm。 The length of the hair is not particularly limited, and may be, for example, 6 to 12 mm.

手柄部6係從頸部4與手柄部6之邊界(即,頸部後端)P2朝向手柄體後端7逐漸縮窄接著維持任意之直徑的狀態下而到達手柄體後端7的形狀。手柄部6之截面輪廓與後述之頸部後端P2之截面輪廓為大致相似形。 The handle portion 6 is formed such that the boundary between the neck portion 4 and the handle portion 6 (i.e., the neck rear end) P2 gradually narrows toward the rear end 7 of the handle body and then maintains an arbitrary diameter to reach the rear end 7 of the handle body. The cross-sectional profile of the handle portion 6 is substantially similar to the cross-sectional profile of the neck rear end P2 to be described later.

頸部4係將頭部2與手柄部6連接者,且為隨著從頭部2側朝向手柄部6側來擴大直徑之形狀。 The neck portion 4 has a shape in which the head portion 2 is connected to the handle portion 6 and has a diameter that increases from the side of the head portion 2 toward the side of the handle portion 6.

頸部4係使頭部2與頸部4之邊界(即,頸部前端)P1為最小之截面積,並使頸部後端P2為最大之面積。頸部前端P1之截面積可考慮手柄體10之材質來決定,例如材質為彎曲彈性率2000MPa以上之樹脂時,宜為7~12.6mm2。如為上述下限值以上,則頸部4之強度為相當充足,如為上述上限值以下,則可更加提高在口腔內之操作性。 The neck 4 is such that the boundary between the head 2 and the neck 4 (i.e., the front end of the neck) P1 is the smallest cross-sectional area, and the neck rear end P2 is the largest area. The cross-sectional area of the neck front end P1 can be determined in consideration of the material of the handle body 10. For example, when the material is a resin having a bending modulus of 2000 MPa or more, it is preferably 7 to 12.6 mm 2 . If it is more than the above lower limit value, the strength of the neck portion 4 is sufficiently sufficient, and if it is at most the above upper limit value, the operability in the oral cavity can be further improved.

頸部後端P2之截面積可考慮手柄體10之材質來決定,例如,材質為彎曲彈性率2000MPa以上之樹脂時,宜為60~150mm2。 The cross-sectional area of the neck end P2 can be determined in consideration of the material of the handle body 10. For example, when the material is a resin having a bending modulus of 2000 MPa or more, it is preferably 60 to 150 mm 2 .

如為上述範圍內可將頸部4之彎曲量適當地限制,並用適當之刷掃壓力來將清掃對象部位清掃。 In the above range, the amount of bending of the neck portion 4 can be appropriately restricted, and the cleaning target portion can be cleaned by appropriate brushing pressure.

頸部前端P1係形成頭部2之俯視形狀的切除邊角之曲線的終點(即,形成切除邊角之曲線的彎曲方向所變化之位置)。又,頸部後端P2在俯視下為頸部4之擴大寬度結束之位置。 The neck front end P1 forms the end point of the curve of the cut corner of the top shape of the head portion 2 (i.e., the position at which the bending direction of the curve of the cut corner is changed). Further, the neck rear end P2 is a position where the enlarged width of the neck portion 4 is completed in plan view.

頸部4係隨著從頭部2側朝向手柄部6側,而使截面輪廓有所變化者。本說明書中所謂的截面輪廓係與長度 方向正交之截面的輪廓。 The neck portion 4 has a change in cross-sectional profile as it goes from the head 2 side toward the handle portion 6 side. The cross-sectional profile and length referred to in this specification The outline of the section orthogonal to the direction.

如圖1~2所示,本實施形態之頸部4係使頸部前端P1之截面輪廓為大致圓形(將包含頸部前端P1且使截面輪廓為大致圓形之部分作為圓形部40),隨著該大致圓形之截面輪廓朝向手柄部6側,成為大致四角形之截面輪廓(將使截面輪廓為大致四角形之部分作為四角形部42),進而隨著大致四角形之截面輪廓朝向手柄部6側,成為大致六角形之截面輪廓(將包含頸部後端P2且使截面輪廓為大致六角形之部分作為多角形部44)。從多角形部44到手柄體後端7,手柄體10之兩側面形成有稜線46、46。 As shown in FIGS. 1 and 2, in the neck portion 4 of the present embodiment, the cross-sectional contour of the neck distal end P1 is substantially circular (the portion including the neck distal end P1 and having a substantially circular cross-sectional profile is defined as the circular portion 40). With the substantially circular cross-sectional profile facing the handle portion 6 side, a substantially quadrangular cross-sectional profile (a portion having a substantially quadrangular cross-sectional profile as a quadrangular portion 42) is formed, and the cross-sectional profile of the substantially quadrangular shape faces the handle portion. The 6 side has a substantially hexagonal cross-sectional profile (a portion including a neck rear end P2 and a cross-sectional profile having a substantially hexagonal shape as the polygonal portion 44). From the polygonal portion 44 to the rear end 7 of the handle body, ridge lines 46, 46 are formed on both side faces of the handle body 10.

圓形部40、四角形部42、及多角形部44係連續地形成而使頸部4之截面輪廓慢慢地變化。所謂的大致四角形係包含頂部為用曲線所切除邊角之形狀的概念,且所謂的大致六角形,為頂部包含用曲線切除邊角之形狀的概念。又,圖2A~圖2C中之符號Q為圓形部40之截面輪廓的中心線。 The circular portion 40, the quadrangular portion 42, and the polygonal portion 44 are continuously formed to gradually change the cross-sectional profile of the neck portion 4. The so-called substantially quadrangular shape includes the concept that the top is a shape of a corner cut by a curve, and the so-called substantially hexagonal shape is a concept in which the top includes a shape in which a corner is cut by a curve. Further, the symbol Q in FIGS. 2A to 2C is the center line of the cross-sectional profile of the circular portion 40.

如圖2A所示,圓形部40係截面輪廓為大致正圓形。所謂的大致正圓形係厚度t1/寬度w1所表現之比為0.95~1.05。上述大致圓形與大致正圓形係同樣地來定義。圓形部40藉由截面輪廓為大致正圓形,便難以限制彎曲方向,則植毛面20之方向可根據清掃對象部位來變動,更加提高清掃效果。 As shown in FIG. 2A, the circular portion 40 has a substantially circular cross-sectional profile. The ratio of the substantially circular circle thickness t1/width w1 is 0.95 to 1.05. The above-mentioned substantially circular shape is defined in the same manner as the substantially circular shape. Since the circular portion 40 has a substantially circular cross-sectional profile, it is difficult to restrict the bending direction, and the direction of the hair-planting surface 20 can be changed according to the cleaning target portion, thereby further improving the cleaning effect.

厚度t1可考慮手柄體10之材質來決定,例如,材質為彎曲彈性率2000MPa以上之樹脂時,宜為3.0~4.0mm,更宜為3.0~3.5mm。如為上述下限值以上,可適度地限制彎曲 量,如為上述上限值以下,可更加提高在口腔內之操作性。 The thickness t1 can be determined in consideration of the material of the handle body 10. For example, when the material is a resin having a bending modulus of 2000 MPa or more, it is preferably 3.0 to 4.0 mm, more preferably 3.0 to 3.5 mm. If it is above the above lower limit value, the bending can be moderately restricted. If the amount is at most the above upper limit value, the operability in the oral cavity can be further improved.

寬度w1與厚度t1相同。 The width w1 is the same as the thickness t1.

如圖2B所示,四角形部42係截面輪廓為大致正方形,該大致正方形係用頸部4之表面、背面及側面來形成各邊。所謂的大致正方形係厚度t2/寬度w2所表現之比為0.95~1.05。四角形部42係截面輪廓為大致正方形,且由於各邊用頸部4之表面、背面及側面來形成,因此彎曲方向限制於頸部4之厚度方向或是寬度方向。 As shown in FIG. 2B, the quadrangular portion 42 has a substantially square cross-sectional profile, and the substantially square shape forms the sides by the front surface, the back surface, and the side surface of the neck portion 4. The ratio of the so-called substantially square thickness t2/width w2 is 0.95 to 1.05. The quadrangular portion 42 has a substantially square cross-sectional profile, and since each side is formed by the surface, the back surface, and the side surface of the neck portion 4, the bending direction is limited to the thickness direction or the width direction of the neck portion 4.

厚度t2可考慮手柄體10之材質來決定,例如,材質為彎曲彈性率2000MPa以上之樹脂時,宜為3.0~6.0mm,更宜為4.0~5.0mm。如為上述下限值以上,可充分地限制彎曲方向,如為上述上限值以下,可更加提高在口腔內之操作性。 The thickness t2 can be determined in consideration of the material of the handle body 10. For example, when the material is a resin having a bending modulus of 2000 MPa or more, it is preferably 3.0 to 6.0 mm, more preferably 4.0 to 5.0 mm. If it is more than the above lower limit value, the bending direction can be sufficiently restricted, and if it is at most the above upper limit value, the operability in the oral cavity can be further improved.

寬度w2係與厚度t2相同。 The width w2 is the same as the thickness t2.

如圖2C所示,多角形部44係使截面輪廓為大致六角形。且使該大致六角形為在頸部4之兩側面位於頂部50、50之形狀,該頂部50相連,形成稜線46之一部分。前述大致六角形係上邊52用頸部4之表面來形成,且與上邊52相對向之下邊54則用頸部4之背面來形成之形狀,比起寬度w3厚度t3要較短,即,在厚度方向為扁平之形狀。多角形部44藉由採用上述截面輪廓,利用側面所形成之稜線46,成為在寬度方向難以彎曲者,由於在厚度方向為扁平,因此成為在厚度方向容易彎曲者。進而,由於多角形部44係表面及背面為平面,因此難以限制在厚度方向的彎曲。 As shown in Fig. 2C, the polygonal portion 44 has a substantially hexagonal cross-sectional profile. And the substantially hexagonal shape is in the shape of the top portions 50, 50 on both sides of the neck portion 4, the top portions 50 being joined to form a portion of the ridge line 46. The substantially hexagonal upper side 52 is formed by the surface of the neck portion 4, and the lower side 54 opposite to the upper side 52 is formed by the back surface of the neck portion 4, which is shorter than the width w3 and the thickness t3, that is, The thickness direction is a flat shape. By using the above-described cross-sectional profile, the polygonal portion 44 is made to be difficult to bend in the width direction by the ridge line 46 formed on the side surface, and is flat in the thickness direction, so that it is easily bent in the thickness direction. Further, since the surface and the back surface of the polygonal portion 44 are flat, it is difficult to restrict the bending in the thickness direction.

厚度t3/寬度w3所表現之比可考慮手柄體10之材 質來決定,例如,宜為0.50~0.95,更宜為0.70~0.90。厚度t3可考慮手柄體10之材質來決定,例如,材質為彎曲彈性率2000MPa以上之樹脂時,宜為6~12mm,更宜為8~10mm。如為上述下限值以上,可充分地限制彎曲方向,如為上述上限值以下,可更加彈性地彎曲頸部4,將刷掃壓力定為更加適當者。 The ratio of the thickness t3/width w3 can be considered as the material of the handle body 10. The quality is determined, for example, preferably from 0.50 to 0.95, more preferably from 0.70 to 0.90. The thickness t3 can be determined in consideration of the material of the handle body 10. For example, when the material is a resin having a bending modulus of 2000 MPa or more, it is preferably 6 to 12 mm, more preferably 8 to 10 mm. If it is more than the above lower limit value, the bending direction can be sufficiently restricted, and if it is equal to or less than the above upper limit value, the neck portion 4 can be more elastically bent, and the brushing pressure can be made more appropriate.

寬度w3可考慮手柄體10之材質來決定,例如,材質為彎曲彈性率2000MPa以上之樹脂時,宜為8~20mm,更宜為10~15mm。如為上述下限值以上,可充分限制寬度方向之彎曲,如為上述上限值以下,可更加提高操作性。 The width w3 can be determined in consideration of the material of the handle body 10. For example, when the material is a resin having a bending modulus of 2000 MPa or more, it is preferably 8 to 20 mm, more preferably 10 to 15 mm. If it is more than the above lower limit value, the bending in the width direction can be sufficiently restricted, and if it is at most the above upper limit value, the operability can be further improved.

頸部4之長度可考慮頭部之長度L3來決定,例如,從手柄體前端9到頸部後端P2為止的長度L2宜為70~100mm之長度。如長度L2為上述下限值以上,可更加提高在口腔內之操作性,如為上述上限值以下,可適當地限制頸部4之彎曲量。 The length of the neck portion 4 can be determined in consideration of the length L3 of the head. For example, the length L2 from the front end 9 of the handle body to the rear end P2 of the neck portion is preferably a length of 70 to 100 mm. When the length L2 is at least the above lower limit value, the operability in the oral cavity can be further improved, and if it is at most the above upper limit value, the amount of bending of the neck portion 4 can be appropriately restricted.

又,從手柄體前端9到稜線46之前端(稜線前端)47為止的長度L4宜為60mm以上,更宜為65mm以上。長度L4之上限係例如可為90mm。如長度L4為上述下限值以上,可防止稜線46與口腔內接觸,並防止清掃時產生之違和感。如長度L4為上述上限值以下,可適當地限制頸部4之彎曲量。 Further, the length L4 from the front end 9 of the handle body to the front end (the ridge end) 47 of the ridge line 46 is preferably 60 mm or more, and more preferably 65 mm or more. The upper limit of the length L4 may be, for example, 90 mm. If the length L4 is equal to or higher than the above lower limit value, the ridge line 46 can be prevented from coming into contact with the inside of the oral cavity, and the feeling of discomfort generated during cleaning can be prevented. If the length L4 is equal to or less than the above upper limit value, the amount of bending of the neck portion 4 can be appropriately restricted.

本實施形態之牙刷1係以習知眾所皆知之牙刷的製造方法為基準來製造。 The toothbrush 1 of the present embodiment is manufactured on the basis of a conventionally known method for producing a toothbrush.

例如,對模具射出硬質樹脂,將手柄體10成形。接著,對獲得之手柄體10的植毛面20設植毛束,藉此獲得牙刷1。 設植毛束之方法係例如,可舉例有:使毛束成二折並將已夾入其間之平線嵌入植毛穴22藉此設植毛束的平線式植毛、將毛束之下端朝成為植毛部之溶融樹脂中壓入且固定的熱融著法、及將毛束之下端加熱且形成溶融塊之後對模具中注入溶融樹脂且將植毛部成形的模內法等。 For example, the handle body 10 is formed by injecting a hard resin into the mold. Next, a tuft of hair is applied to the hair-growing surface 20 of the obtained handle body 10, whereby the toothbrush 1 is obtained. The method of arranging the tufts is, for example, a method in which the hair bundle is folded into two and the flat line that has been sandwiched therebetween is inserted into the planting hair hole 22, thereby setting the hairline of the hair bundle, and the lower end of the hair bundle is turned into a hair planting. A hot-melt method in which a molten resin is pressed in and fixed, and an in-mold method in which a lower portion of the hair bundle is heated to form a molten mass, and then a molten resin is injected into the mold to form a hair-planting portion.

接著,說明本實施形態之牙刷1的使用方法。 Next, a method of using the toothbrush 1 of the present embodiment will be described.

首先,握持手柄部6。握持手柄部6之形態並無特別限定,可為掌握式,亦可為筆握式。通常,為了對於對象部位施加壓力並清掃,即使在任一握持形態,都會將大拇指等置於頸部後端P2附近,來握持手柄部6。 First, the handle portion 6 is gripped. The form in which the handle portion 6 is gripped is not particularly limited, and may be a grasping type or a pen grip type. Usually, in order to apply pressure to the target portion and clean it, the thumb portion or the like is placed near the rear end P2 of the neck to grip the handle portion 6 even in any holding form.

接著,對口腔內插入頭部2,用置於多角形部44附近之大拇指等來押壓柄部6並使植毛部對清掃對象部位滑動。施加於手柄部6之力透過頸部4傳到頭部2,進而從頭部2傳到植毛部,藉此植毛部對清掃對象部位施加壓力並清掃。此時,圓形部40由於截面輪廓為大致正圓形,因此彎曲方向並無限制。故,圓形部40根據清掃對象部位之形狀彎曲,使植毛部對於清掃對象部位適當地接觸。 Next, the head portion 2 is inserted into the oral cavity, and the handle portion 6 is pressed by a thumb or the like placed in the vicinity of the polygonal portion 44, and the hair-planting portion is slid to the cleaning target portion. The force applied to the handle portion 6 is transmitted to the head portion 2 through the neck portion 4, and further transmitted from the head portion 2 to the hair-planting portion, whereby the hair-planting portion applies pressure to the cleaning target portion and cleans it. At this time, since the circular portion 40 has a substantially circular cross-sectional profile, the bending direction is not limited. Therefore, the circular portion 40 is bent in accordance with the shape of the cleaning target portion, and the planting portion is appropriately brought into contact with the cleaning target portion.

在此,當在頸部4整體無限制彎曲方向時,會失去從手柄部6傳到頸部4之力量,或是頸部4過度彎曲,無法用適當之刷掃壓力來清掃。 Here, when the entire neck portion 4 has no undefined bending direction, the force transmitted from the handle portion 6 to the neck portion 4 is lost, or the neck portion 4 is excessively bent, and it is impossible to clean with appropriate brushing pressure.

在本實施形態中,多角形部44利用形成於兩側面之稜線46與在厚度方向扁平之截面輪廓,限制成在寬度方向難以彎曲,在厚度方向容易彎曲。故,施加於手柄部6之力量利用多角形部44,受制於厚度方向之力量,傳到四角形部 42。四角形部42係截面輪廓為大致正方形,該大致正方形之各邊用頸部4之表面、背面及側面來形成,彎曲方向限制於厚度方向及寬度方向。故,不會過度失去傳到四角形部42之力量,而可傳至圓形部40。 In the present embodiment, the polygonal portion 44 is restricted from being bent in the width direction by the ridge line 46 formed on both side faces and the cross-sectional profile flat in the thickness direction, and is easily bent in the thickness direction. Therefore, the force applied to the handle portion 6 is controlled by the polygonal portion 44, and is transmitted to the square portion by the force in the thickness direction. 42. The quadrangular portion 42 has a substantially square cross-sectional profile, and each of the substantially square sides is formed by the front surface, the back surface, and the side surface of the neck portion 4, and the bending direction is limited to the thickness direction and the width direction. Therefore, the force transmitted to the square portion 42 is not excessively lost, but can be transmitted to the circular portion 40.

此外,頸部4隨著從頸部前端P1朝向頸部後端P2,其截面輪廓為大致正圓形、大致正方形,由於在厚度方向變化成扁平之大致六角形,因此從頸部前端P1朝向頸部後端P2可慢慢地限制彎曲方向。故,即使頸部4變細,頸部4整體也不會過度軟弱,使植毛部用適當之狀態與清掃對象部位接觸,且將力量傳達至頭部2而使其變成適當之刷掃壓力。 Further, the neck portion 4 has a substantially circular cross section and a substantially square shape as it goes from the neck front end P1 toward the neck rear end P2, and is oriented from the neck front end P1 due to a flat hexagonal shape in the thickness direction. The neck rear end P2 can slowly limit the bending direction. Therefore, even if the neck portion 4 is thinned, the entire neck portion 4 is not excessively weak, so that the hair-planting portion comes into contact with the cleaning target portion in an appropriate state, and the force is transmitted to the head portion 2 to become an appropriate brushing pressure.

進而,由於本實施形態之牙刷1係使頸部4隨著從頸部後端P2朝向頸部前端P1為窄細之形狀,因此頸部4整體可彈性地彎曲,更加適當地緩和施加於清掃對象部位之壓力,將刷掃壓力定為更加適當。 Further, in the toothbrush 1 of the present embodiment, the neck portion 4 has a narrow shape from the neck rear end P2 toward the neck front end P1, so that the entire neck portion 4 can be elastically bent and more appropriately applied to the cleaning. The pressure of the target part is more appropriate for the brushing pressure.

如上所述,根據本實施形態之牙刷,頸部係使頭部側之截面輪廓為大致圓形,隨著大致圓形之截面輪廓朝向手柄部側,成為用表面、背面及側面形成各邊之大致四角形的截面輪廓,進而由於隨著大致四角形之截面輪廓朝向手柄部側,成為在兩側面位於頂部且在厚度方向扁平之大致多角形,因此即使使頸部變細,亦可發揮很高的清掃效果。 As described above, according to the toothbrush of the present embodiment, the neck portion has a substantially circular cross-sectional profile on the head side, and the sides are formed by the front surface, the back surface, and the side surface as the substantially circular cross-sectional contour faces the handle portion side. The substantially quadrangular cross-sectional profile, and the substantially quadrangular cross-sectional profile toward the handle portion side, is a substantially polygonal shape that is flat on both sides and flat in the thickness direction. Therefore, even if the neck portion is made thinner, it can be made high. Cleaning effect.

The cross-sectional profile of the circular portion can be appropriately set in consideration of the function of the toothbrush or the like. For example, in order to obtain a toothbrush which is softer and has a good touch, it is preferable to adopt a flat shape in the thickness direction of the cross section of the circular portion. By making it flat in the thickness direction, the brushing pressure can be further alleviated.

在上述之實施形態中,使四角形部之截面輪廓為大致正方形,但本發明不限於此,四角形部之截面輪廓亦可為長方形。四角形部之截面輪廓可考慮牙刷之功能等來適宜地設定。例如,為了獲得更加柔軟且觸感良好之牙刷,宜將四角形部之截面輪廓在厚度方向採取扁平之形狀。藉由使其在厚度方向為扁平之形狀,可更加緩和刷掃壓力。 In the above embodiment, the cross-sectional profile of the quadrangular portion is substantially square, but the present invention is not limited thereto, and the cross-sectional profile of the quadrangular portion may be rectangular. The cross-sectional profile of the quadrangular portion can be appropriately set in consideration of the function of the toothbrush or the like. For example, in order to obtain a softer and more tactile toothbrush, the cross-sectional profile of the quadrangular portion should be flat in the thickness direction. By making it flat in the thickness direction, the brushing pressure can be further alleviated.

又,在上述實施形態中,使四角形部之截面輪廓為於頂部形成曲線之切除邊角的形狀,但本發明不限於此,即使於頂部不形成切除邊角亦可。但,在清掃時將四角形部置於唇等而產生之違和感加以緩和的觀點看來,宜於頂部形成曲線之切除邊角為佳。 Further, in the above embodiment, the cross-sectional profile of the quadrangular portion is a shape in which the cut corner of the curve is formed at the top, but the present invention is not limited thereto, and the cut corner may not be formed at the top. However, it is preferable that the cut corner of the top forming curve is preferable from the viewpoint of alleviating the feeling of discomfort caused by placing the square portion on the lip or the like during cleaning.

在上述實施形態中,多角形部之截面輪廓為大致六角形,但本發明不限於此,多角形部之截面輪廓亦可為大致五角形、大致八角形等、大致六角形以外之大致多角形。所謂的大致五角形、大致八角形等之大致多角形,係與大致四角形及大致六角形同樣地,為頂部包含用曲線切除邊角之形狀的概念。 In the above embodiment, the cross-sectional profile of the polygonal portion is substantially hexagonal. However, the present invention is not limited thereto, and the cross-sectional profile of the polygonal portion may be a substantially polygonal shape such as a substantially pentagon shape, a substantially octagonal shape, or the like, and a substantially hexagonal shape. The substantially polygonal shape such as a substantially pentagon or a substantially octagonal shape is similar to a substantially quadrangular shape and a substantially hexagonal shape, and the top portion includes a concept of cutting a corner shape by a curve.

在上述實施形態中,多角形部之截面輪廓係不使頂部位在表面及背面,且無形成稜線(即,表面與背面為平面),但本發明不限於此,可在表面與背面雙方或是任一方形成 有稜線。但,從使多角形部只在厚度方向容易彎曲之觀點看來,宜使多角形部之表面與背面為平面。 In the above embodiment, the cross-sectional profile of the polygonal portion is such that the top portion is not on the front surface and the back surface, and the ridge line is not formed (that is, the surface and the back surface are flat). However, the present invention is not limited thereto, and may be on both the front surface and the back surface or Is formed by either side There are ridges. However, from the viewpoint of making the polygonal portion easy to bend only in the thickness direction, it is preferable that the surface and the back surface of the polygonal portion are flat.

在上述實施形態中,使頸部前端之截面輪廓為大致正圓形,在包含頸部前端之區域形成有圓形部,但本發明不限於此,例如,亦可使頸部前端之截面輪廓為大致圓形以外之形狀,從頸部前端分開之位置形成圓形部。但,從使植毛部對於清掃對象部位更加適當地接觸之觀點看來,宜使頸部前端之截面輪廓為大致圓形。 In the above embodiment, the cross-sectional contour of the distal end of the neck portion is substantially round, and a circular portion is formed in a region including the distal end of the neck portion. However, the present invention is not limited thereto, and for example, the cross-sectional profile of the front end of the neck portion may be In the shape other than the substantially circular shape, a circular portion is formed at a position separated from the front end of the neck. However, from the viewpoint of making the hair-planting portion more suitable for the cleaning target portion, it is preferable that the cross-sectional contour of the neck front end is substantially circular.

在上述實施形態中,使頸部後端之截面輪廓在厚度方向為扁平之大致六角形,包含頸部後端之區域形成有多角形部,但本發明不限於此,多角形部亦可形成於從頸部後端分開之位置。但,從加適當地限制頸部之彎曲量更之觀點看來,頸部後端之截面輪廓宜在厚度方向為扁平之大致六角形。 In the above embodiment, the cross-sectional profile of the rear end of the neck portion is substantially hexagonal in the thickness direction, and the polygonal rear portion is formed in the region including the rear end of the neck. However, the present invention is not limited thereto, and the polygonal portion may be formed. At a position separated from the back end of the neck. However, from the viewpoint of appropriately limiting the amount of bending of the neck, the cross-sectional profile of the rear end of the neck should be substantially hexagonal in the thickness direction.

在上述實施形態中,使頸部隨著從頸部前端朝向頸部後端來擴大直徑,但本發明不限於此,頸部亦可隨著從頸部前端朝向頸部後端縮小直徑,從頸部前端到頸部後端亦可為大致相同之直徑。所謂的大致相同之直徑係可容許直徑為-15%~15%程度之偏差的表現,該偏差宜為-10%~10%,更宜為-5%~5%。但,從更加適當地緩和刷掃壓力之觀點看來,頸部宜隨著從頸部前端朝向頸部後端來擴大直徑。 In the above embodiment, the neck is enlarged in diameter from the front end of the neck toward the rear end of the neck.
