Description
本發明係有關於一種牙刷。 The invention relates to a toothbrush.
本申請案基於2011年8月26日在日本所申請之特願2011-184569號，主張優先權，並於此引用其內容。 The present application claims priority from Japanese Patent Application No. 2011-184569, filed on Jan.
作為牙刷之基本功能，口腔內的清潔效果或按摩效果為一需求，而藉由提升其基本功能，開始謀求牙刷的高附加價值。為了達到提升其基本性能，於把手部賦予柔軟性，並將植毛部抵觸清潔對象部(齒面、咬合面、齒間部、牙齦等)的壓力(刷壓)加以緩和，開始進行嘗試改善觸感。 As a basic function of the toothbrush, the cleaning effect or the massage effect in the oral cavity is a requirement, and by increasing the basic functions, the high added value of the toothbrush is sought. In order to improve the basic performance, softening is imparted to the handle portion, and the pressure (brushing pressure) of the hair-receiving portion against the cleaning target portion (tooth surface, occlusal surface, interdental portion, gums, etc.) is alleviated, and an attempt is made to improve the touch. sense.
作為緩和刷壓的牙刷，例如提出的一種牙刷，係於柄部與頭部之間具有整體彎曲的部分，該整體彎曲的部分材係相對長軸於橫切方向具有折軸，於彎折處貫通有彈性體材(例如，專利文獻1)。 As a toothbrush for relieving brush pressure, for example, a toothbrush is proposed which has an integrally curved portion between the handle and the head, and the integrally curved portion has a folding axis with respect to the longitudinal axis in the transverse direction at the bend. An elastic body is penetrated (for example, Patent Document 1).
又，提出的一種牙刷，係由與發泡劑混合的彈性體所形成，刷柄的區域係發泡形成，頭部的橫剖面區域大致係實體形成(例如，專利文獻2)。 Further, a toothbrush proposed is formed of an elastomer mixed with a foaming agent, and a region of the handle is foamed, and a cross-sectional area of the head is substantially solid (for example, Patent Document 2).
即便如此，牙刷的附加價值不僅如上述緩和刷壓的牙刷而提升功能者，外觀上的特徵亦為一需求。例如，在一部分的市場上，偏好將把手部的後端側變粗、具份量感的牙刷。一般而言，若將把手部變粗，則手持部分變得 容易滑動、柔軟性下降，造成無法緩和刷壓，變得容易折損觸感。 Even so, the added value of the toothbrush is not only a function of lifting the brushed toothbrush as described above, but also a feature in appearance. For example, in some markets, a toothbrush that thickens the rear end side of the handle portion and has a sense of weight is preferred. In general, if the handle portion is thickened, the hand-held portion becomes It is easy to slide and the softness is lowered, so that the brushing pressure cannot be alleviated, and the touch is easily broken.
針對這樣的問題，例如提出的一種牙刷，係設有於把手部之長方向延伸的複數個凹條部及凸條部，凹條部與凸條部係於把手體的寬度方向交互地並列而形成，且被覆材披覆凹條部及凸條部所形成的面上(例如，專利文獻3)。依據專利文獻3的發明，提升止滑效果或操作性，且達到外觀上的差異化。 In order to solve such a problem, for example, a toothbrush is provided with a plurality of concave strip portions and a ridge portion extending in the longitudinal direction of the handle portion, and the concave strip portion and the ridge portion are alternately juxtaposed in the width direction of the handle body. The cover material is formed on the surface formed by the groove portion and the ridge portion (for example, Patent Document 3). According to the invention of Patent Document 3, the anti-slip effect or the operability is improved, and the difference in appearance is achieved.
又，提出的一種牙刷，係將把手之至少握部一部分的剖面形狀形成：朝向具有頭部之刷毛面的面而開口的略U字形，於該開口凹部、把手之表背設置貫通孔，且沿著把手具有：密充於貫通孔、跨越把手之表背，越過把手的全外周而連續之熱塑性彈性體材料的被覆部(例如，專利文獻4)。依據專利文獻4的發明，藉由適當地抑制刷壓，達到使用感的提升。 Further, a toothbrush is proposed in which a cross-sectional shape of at least a part of a grip portion of the handle is formed in a slightly U-shape opening toward a surface having a bristle surface of the head, and a through hole is formed in the opening recess and the front and back of the handle, and The handle portion has a covering portion of a thermoplastic elastomer material that is adhered to the through hole, across the front and back of the handle, and over the entire periphery of the handle (for example, Patent Document 4). According to the invention of Patent Document 4, the improvement in the feeling of use is achieved by appropriately suppressing the brush pressure.

中間部12係在清潔口腔內時，透過被覆體20以大拇指押壓的部分。從植毛部落在清潔對象部的壓力(刷壓)，主要係藉由押壓中間部12的大拇指的力道強弱來進行調節。 The intermediate portion 12 is a portion that is pressed by the thumb 20 by the thumb when the oral cavity is cleaned. The pressure (brushing pressure) from the planting tribe in the cleaning target portion is mainly adjusted by pressing the strength of the thumb of the intermediate portion 12.
如圖6(A)及圖6(B)所示，中間部12的形狀為：從後端41朝向頸部6，以略相同的寬度，使表面與背面之距離(即厚度)變短，接著使表面與背面之距離(即厚度)變長。於本實施形態中，中間部12之後端41側的端部的剖面形狀、以及中間部12之前端51側的端部的剖面形狀為略正圓形。 As shown in FIGS. 6(A) and 6(B), the intermediate portion 12 has a shape in which the distance from the rear surface 41 toward the neck portion 6 is slightly the same, and the distance between the surface and the back surface (ie, the thickness) is shortened. The distance between the surface and the back surface (i.e., the thickness) is then lengthened. In the present embodiment, the cross-sectional shape of the end portion on the rear end 41 side of the intermediate portion 12 and the cross-sectional shape of the end portion on the front end 51 side of the intermediate portion 12 are slightly rounded.
略相同係指可容許-10°~10°左右之偏差的表現，該偏差宜為-5°~5°。又，略正圓形係指可容許偏離正圓形-10°~10°左右的表現，該偏差宜為-5°~5°。 Slightly the same means that the deviation of -10°~10° can be tolerated, and the deviation should be -5°~5°. Further, the slightly rounded shape means an expression which is tolerable from about -10° to 10° from the true circle, and the deviation is preferably -5° to 5°.
如圖6C所示，中間部12的厚度變得最薄的部分的剖面，係以正交於植毛面52之方向作為短徑的略橢圓形，於厚度方向為扁平的形狀。 As shown in FIG. 6C, the cross section of the portion where the thickness of the intermediate portion 12 is the thinnest is a substantially elliptical shape having a short diameter in a direction orthogonal to the hair-planting surface 52, and a flat shape in the thickness direction.
即，中間部12在中間的區域，表面及背面為凹面者。 That is, the intermediate portion 12 is in the middle region, and the surface and the back surface are concave.
藉由中間部12為此般形狀，頸部6整體於表面方向與背面方向柔彈地彎曲，使觸感更加良好。 Since the intermediate portion 12 has such a shape, the neck portion 6 is flexibly bent in the surface direction and the back surface direction as a whole, and the touch feeling is further improved.

被覆體20係使用時手指抵觸的部分，一方面面積越大，越可容易防止握持之手指的滑動，另一方面，面積太大時，因大量使用軟質樹脂，故於原料成本面上不經濟。因此，被覆體20宜為設置於：調節牙刷1之動作或刷壓的大拇指或食指頻繁抵觸之處。即，宜為決定被覆體20的長度L4與位置，以在從頸部6之底端朝向後端41之20~50%的區域設置被覆體20。 The covering body 20 is a portion in which the fingers are in contact with each other. On the one hand, the larger the area, the easier it is to prevent the sliding of the gripping fingers. On the other hand, when the area is too large, the soft resin is used in a large amount, so the raw material cost is not economic. Therefore, the covering body 20 is preferably disposed at a position where the thumb or the index finger which adjusts the action or brushing of the toothbrush 1 frequently collides. That is, it is preferable to set the length L4 and the position of the covering body 20 so that the covering body 20 is provided in a region from the bottom end of the neck portion 6 toward the rear end 41 of 20 to 50%.
本體10係藉由硬質樹脂而一體成形者，係可斟酌牙刷1所要求之剛性或機械特性等而決定，例如可舉例：彎曲強度超過3000N/cm2者，宜為彎曲強度4000~15000N/cm2 者。此般硬質樹脂例如可舉例：聚丙烯(PP)、聚對苯二甲酸乙二酯(PET)、聚對苯二甲酸丁二酯(PBT)、聚對苯二甲酸環乙烷二甲醇酯(PCT)、聚縮醛(POM)、聚苯乙烯(PS)、丙烯腈-丁二烯-苯乙烯樹脂(ABS)、丙酸纖維素(CP)、聚芳香酯、聚碳酸酯、丙烯腈/苯乙烯樹脂(AS)等，其中宜為PBT。這些係可單獨1種或適當組合2種以上來使用。 The main body 10 is integrally molded by a hard resin, and may be determined in consideration of the rigidity or mechanical properties required for the toothbrush 1. For example, if the bending strength exceeds 3000 N/cm 2 , the bending strength is preferably 4000 to 15000 N/cm. 2 people. Examples of such a hard resin include polypropylene (PP), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polybutylene terephthalate (methanol). PCT), polyacetal (POM), polystyrene (PS), acrylonitrile-butadiene-styrene resin (ABS), cellulose propionate (CP), polyarylate, polycarbonate, acrylonitrile/ Styrene resin (AS), etc., of which PBT is preferred. These may be used alone or in combination of two or more.
構成被覆體20的軟質樹脂係只要在握持把手部2時，具有合手指般的彈力者即可，shore A硬度宜為90以下，尤以10~40為宜。此般軟質樹脂，例如可舉例：聚烯系彈性體、苯乙烯系彈性體、聚酯系彈性體、聚氨酯型熱塑性彈性體等彈性體樹脂、矽等。 The soft resin constituting the covering body 20 may have a finger-like elastic force when the grip portion 2 is gripped, and the Shore A hardness is preferably 90 or less, and particularly preferably 10 to 40. Examples of such a soft resin include an elastomer resin such as a polyolefin elastomer, a styrene elastomer, a polyester elastomer, and a polyurethane thermoplastic elastomer, and the like.
又，構成被覆體20的軟質樹脂，相對可視光可為透明或半透明之物，相對可視光亦可不具有透明性之物。然而，因通過被覆體20可辨視第一蛇腹部13a或第二蛇腹部13b時，達到設計性的提升，故構成被覆體20的樹脂相對可視光宜為透明或半透明之物。 Further, the soft resin constituting the covering member 20 may be transparent or translucent with respect to visible light, and may not have transparency with respect to visible light. However, when the first snake belly 13a or the second snake belly 13b is discernible by the covering body 20, the design is improved, so that the resin constituting the covering body 20 is preferably transparent or translucent.
用毛可舉例：其徑往毛端漸漸變小的用毛(漸縮毛)、除去毛端的圓部，外徑大致相同的用毛(直線毛)、漸縮毛或直線毛的毛端為分岔的分岔毛等。 The hair can be exemplified by the hair (gradual hair) which gradually becomes smaller toward the hair end, and the round portion where the hair ends are removed, and the hair ends of the hairs (straight hair), the tapering hair or the straight hair having substantially the same outer diameter are Separate hairs, etc.
用毛的材質例如可舉例：6-12尼龍、6-10尼龍等醯胺、PET、聚對苯二甲酸丁二酯(PBT)、聚對苯二甲酸丙二酯(PTT)、聚萘二甲酸乙二酯(PEN)、polybutylene naphthalate(PBN)等聚酯、PP等聚烯、烯系彈性體、苯乙烯系彈性體等(彈性體)樹脂等。 The material of the hair can be exemplified by phthalamide such as 6-12 nylon, 6-10 nylon, PET, polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT), polynaphthalene. A polyester such as polyethylene formate (PEN) or polybutylene naphthalate (PBN), a polyene such as PP, an olefinic elastomer, or a styrene-based elastomer (elastomer) resin.
牙刷1係依照習知的二色成形法而製造。 The toothbrush 1 is manufactured in accordance with a conventional two-color molding method.
例如，於一次模具將硬質樹脂射出，使本體10成形，接著，將本體設置於二次模具內，並將軟質樹脂射出，於前述本體10形成被覆部20，藉此，製得把手體。 For example, the main body 10 is formed by ejecting the hard resin in one mold, and then the main body is placed in the secondary mold, and the soft resin is ejected to form the covering portion 20 on the main body 10, whereby the handle body is obtained.
接著，藉由將毛束植設在所製得之把手體的植毛面52，製得牙刷1。植設毛束的方法例如可舉例：扁線式植毛，其係藉由將毛束折二，並將挾入其之間的扁線打入植毛孔54，來植設毛束；熱熔接法，其係將毛束下端壓入形成植毛部的熔融樹脂中而固定；注模法，其係將毛束的下端加熱而形成熔融塊後，將熔融樹脂注入於模具中，使植毛部成形。 Next, the toothbrush 1 is prepared by implanting a tuft of hair on the hair-planting surface 52 of the prepared handle body. The method of arranging the tufts can be exemplified by a flat-line type of hair-planting by arranging the tufts by folding the tufts and inserting the flat strands that are interposed therebetween into the tufts 54 to form the tufts; The lower end of the tuft is pressed into the molten resin forming the tufting portion to be fixed, and the injection molding method is to heat the lower end of the tuft to form a molten mass, and then inject the molten resin into the mold to form the tufting portion.
接著，針對牙刷的使用方法作說明。 Next, the method of using the toothbrush will be described.
首先，將大拇指的指腹抵觸背面止滑部24，且以其他手指與手掌握住柄部4來握持。此時，於柄部4形成有以硬質樹脂而構成的擴徑部42，因此，可確實地握持柄部4。再加上，於柄部4、頸部6側設有被覆體20，因此，以全手掌握法握持時，主要係大拇指與食指抵觸被覆體20，抵觸的手指可獲得柔軟的觸感。 First, the thumb of the thumb is pressed against the backstop portion 24, and the handle portion 4 is held by the other fingers and hands. At this time, since the enlarged diameter portion 42 made of a hard resin is formed in the shank portion 4, the shank portion 4 can be surely gripped. Further, since the covering member 20 is provided on the side of the handle portion 4 and the neck portion 6, when the grip is held by the full-hand grasping method, the thumb and the index finger are mainly in contact with the covering body 20, and the fingers that are in contact with each other can obtain a soft touch. .
以全手掌握法握持牙刷1，將植毛部抵觸清潔對象部時，對應所抵觸的壓力，即刷壓，植毛面52承受來自清潔對象部的應力。刷壓透過被覆體20，藉由將中間部12押壓之大拇指的力道而進行調整。因此，把手體以大拇指押壓的中間部12為支點，從中間部12至頭部5、於背面方向彎曲。此時，於本體10、較中間部12於頸部6側形成有第二 蛇腹部13b，因此，藉由第二蛇腹部13b會彎曲，可緩和刷壓。 When the toothbrush 1 is held by the full-hand grasping method, when the hair-planting portion is in contact with the cleaning target portion, the hair-carrying surface 52 receives the stress from the cleaning target portion in response to the pressure that is in contact with it, that is, the brushing pressure. The brushing is transmitted through the covering body 20, and is adjusted by the force of the thumb pressed by the intermediate portion 12. Therefore, the handle body is fulcrum with the intermediate portion 12 pressed by the thumb, and is bent from the intermediate portion 12 to the head portion 5 in the back direction. At this time, a second portion is formed on the body portion 10 and the intermediate portion 12 on the neck portion 6 side. The snake abdomen 13b, therefore, can be relieved by the second snake abdomen 13b being bent.
再加上，藉由第二蛇腹部13b會彎曲，以大拇指押壓的力道不會集中在頸部6，從中間部12越至前端51之整體會彎曲，可使對清潔對象物的觸感良好。 In addition, since the second snake abdomen 13b is bent, the force pressed by the thumb is not concentrated on the neck portion 6, and the whole portion from the intermediate portion 12 to the front end 51 is bent, so that the contact with the cleaning object can be made. Feeling good.
更進一步，於本體10、較中間部12於後端41側形成有第一蛇腹部13a，因此，以全手掌握法握持牙刷，清潔口腔內時，第二蛇腹部13a彎曲，使後端41於背面方向位移。藉由第二蛇腹部13a會彎曲，施加於中間部12的大拇指的押壓力緩和，形成刷壓適宜之物。 Further, the first snake belly 13a is formed on the body 10 and the intermediate portion 12 on the side of the rear end 41. Therefore, the toothbrush is held by the full hand grasping method, and when the oral cavity is cleaned, the second snake belly 13a is bent to make the rear end 41 is displaced in the back direction. By the second snake abdomen 13a being bent, the pressing force of the thumb applied to the intermediate portion 12 is relaxed, and a suitable brushing pressure is formed.
依據本實施形態，於被覆體20形成有表面止滑部22、側面止滑部23及背面止滑部24，因此，使用時，握持牙刷1的手指不易滑動。 According to the present embodiment, since the surface slip preventing portion 22, the side surface sliding portion 23, and the back surface sliding portion 24 are formed in the covering member 20, the finger holding the toothbrush 1 is less likely to slide during use.
再加上，被覆體20係設置成：將第一蛇腹部13a、第二蛇腹部13b及中間部12被覆，因此，手指不會直接抵觸第一蛇腹部13a或第二蛇腹部13b。 Further, the covering body 20 is provided such that the first snake belly 13a, the second snake belly 13b, and the intermediate portion 12 are covered, so that the finger does not directly interfere with the first snake belly 13a or the second snake belly 13b.
依據本實施形態，於後端41側形成有第一蛇腹部13a，於頸部6側形成有第二蛇腹部13b，且第一蛇腹部13a與第二蛇腹部13b之間形成有中間部12，因此，可適當地緩和刷壓，使觸感良好。 According to the present embodiment, the first snake abdomen 13a is formed on the rear end 41 side, the second snake belly 13b is formed on the neck portion 6 side, and the intermediate portion 12 is formed between the first snake belly 13a and the second snake belly 13b. Therefore, the brush pressure can be appropriately moderated to make the touch feeling good.
更進一步，本實施形態的牙刷1係藉由以硬質樹脂所構成的擴幅部42而創造出份量感，且藉由第一蛇腹部13a或第二蛇腹部13b可緩和刷壓。因此，用以賦予柔軟性之軟質樹脂的使用位置可僅為：將中間部12、第一蛇腹部13a與第二 蛇腹部13b覆蓋的部分，且能以低廉成本來製造。 Furthermore, the toothbrush 1 of the present embodiment creates a sense of weight by the widened portion 42 made of a hard resin, and the brushing can be alleviated by the first snake abdomen 13a or the second snake belly 13b. Therefore, the soft resin used to impart flexibility can be used only in the middle portion 12, the first snake belly 13a and the second portion. The portion covered by the snake abdomen 13b can be manufactured at a low cost.
