圖1及圖2表示本實施形態的牙刷。圖1是牙刷1的正面圖,圖2是表示構成牙刷1的頭部10的植毛面12的平面圖。
1 and 2 show the toothbrush of this embodiment. FIG. 1 is a front view of the toothbrush 1, and FIG. 2 is a plan view showing the
本實施形態的牙刷1包括:頭部10,植入有牙刷毛的毛束11;頸部20,自頭部10的基端側延伸設置;柄部30,自頸部20的基端側延伸設置(以下,將頭部10與頸部20及柄部30合稱為柄體)。
The toothbrush 1 of the present embodiment includes: a
柄體是整體一體成形為長條狀者,例如為將樹脂作為材料並藉由射出成形所獲得者。 The handle body is one that is integrally molded into a long strip, for example, is obtained by injection molding using resin as a material.
作為柄體的材質,可列舉:聚丙烯樹脂(Polypropylene,PP)、聚縮醛樹脂(聚甲醛(Polyoxymethylene,POM))、聚苯乙烯樹脂(Polystyrene,PS)、聚對苯二甲酸乙二酯樹脂(Polyethylene terephthalate,PET)、聚對苯二甲酸丁二酯樹脂(Polybutylene terephthalate,PBT)、丙烯腈-丁二烯-苯乙烯樹脂(Acrylonitrile Butadiene Styrene,ABS)、聚芳酯樹脂、聚碳酸酯樹脂、丙烯腈-苯乙烯樹脂(Acrylonitrile Styrene,AS)等。該些之中,就強度高、容易將頭部加以薄壁化的方面而言,較佳為聚縮醛樹脂或聚對苯二甲酸丁二酯樹脂。 As the material of the handle body, include: polypropylene resin (Polypropylene, PP), polyacetal resin (Polyoxymethylene (POM)), polystyrene resin (Polystyrene, PS), polyethylene terephthalate Resin (Polyethylene terephthalate, PET), Polybutylene terephthalate (PBT), Acrylonitrile Butadiene Styrene (ABS), polyarylate resin, polycarbonate Resin, Acrylonitrile Styrene (AS), etc. Among these, a polyacetal resin or a polybutylene terephthalate resin is preferable in terms of high strength and easy thickness reduction of the head.
所述樹脂可單獨使用一種,亦可併用兩種以上。 The resin may be used singly, or two or more of them may be used in combination.
另外,為了提昇握持性,柄體的一部分或全部亦可由例如彈性體等柔軟的樹脂包覆。 In addition, in order to improve the grip, part or all of the handle body may be covered with a soft resin such as an elastomer.
如圖2所示,於作為頭部10的表面的植毛面12上形成
有多個(圖2中為23個)植毛孔12a,於植毛孔12a中植入有毛束11。於頭部10的短邊方向上排列有3列植毛孔12a。作為植毛孔12a的短邊方向的排列數,就朝口腔內的插入性而言,較佳為3列以下。另外,關於頭部10的短邊方向的最大寬度,亦就朝口腔內的插入性而言,較佳為8mm以下。
As shown in FIG. 2, it is formed on the flocking
頭部10的最小厚度較佳為2.0mm以上、3.0mm以下。若頭部10的最小厚度為所述上限值以下,則可提昇牙刷1的口腔內的操作性,若為所述下限值以上,則可防止頭部10的強度下降。
The minimum thickness of the
作為構成毛束11的牙刷毛,可使用:其直徑朝向毛尖逐漸變小的牙刷毛(錐形毛)、除毛尖的圓形部分以外外徑大致相同的牙刷毛(直毛),毛尖變成篦狀、球狀、前端分裂狀等形狀的牙刷毛。
As the toothbrush bristles constituting the
作為牙刷毛的材質,例如可列舉:聚醯胺(例如:6-12尼龍、6-10尼龍)、聚酯(例如:聚對苯二甲酸乙二酯、聚對苯二甲酸丁二酯、聚對苯二甲酸丙二酯)、聚烯烴(例如:聚丙烯)、彈性體(例如:烯烴系、苯乙烯系)等合成樹脂材料。該些樹脂材料可單獨使用一種、或將兩種以上組合使用。 As the material of the toothbrush bristles, for example, polyamide (for example: 6-12 nylon, 6-10 nylon), polyester (for example: polyethylene terephthalate, polybutylene terephthalate, Synthetic resin materials such as polytrimethylene terephthalate), polyolefin (e.g. polypropylene), elastomer (e.g. olefin-based, styrene-based). These resin materials can be used alone or in combination of two or more.
另外,牙刷毛亦可為具有芯部與設置於該芯部的外側的至少1層以上的鞘部的多重芯結構。 In addition, the toothbrush bristles may have a multiple core structure having a core and at least one or more sheaths provided on the outside of the core.
牙刷毛的橫剖面形狀較佳為圓形,但未必限定於圓形,可對應於牙刷1的目的用途而設為任意的形狀。例如可設為橢圓形、多邊形(例如三角形、四邊形、五邊形、六邊形等)、異形(例 如星形、三葉的三葉草形、四葉的三葉草形等)等。 The cross-sectional shape of the toothbrush bristles is preferably a circular shape, but is not necessarily limited to a circular shape, and can be set to any shape corresponding to the intended use of the toothbrush 1. For example, it can be set as ellipse, polygon (e.g. triangle, quadrilateral, pentagon, hexagon, etc.), special shape (e.g. Such as star shape, three-leaf clover shape, four-leaf clover shape, etc.) and so on.
構成毛束11的牙刷毛可全部為相同的粗度,亦可將兩種以上的粗度不同的牙刷毛加以組合。另外,就口腔內的使用性或使用感的方面而言,較佳為所選擇的牙刷毛的直徑越小,越縮短牙刷毛的毛長。另外,亦可對應於使用感或刷掃感、清掃效果、耐久性等目的,將粗度不同的多根牙刷毛組合使用。
The toothbrush bristles constituting the
毛束11的植毛方法可為將牙刷毛的毛束對折並將夾在中間的平線打入植毛孔12a中,藉此將毛束11植設至植毛孔12a中的平線式植毛法,亦可為將毛束11熱焊接於頭部10上的熱焊接式植毛法,但就成本低的方面而言,較佳為平線式植毛法。平線是以穿過植毛孔12a的中心部、且跨越植毛孔12a的方式打設至植毛孔12a中。作為平線的材質,例如可列舉黃銅或不鏽鋼等的金屬片,除此以外,亦可列舉硬質塑膠或生物降解性塑膠等。
The tufting method of the
本實施形態中的頭部10的最小厚度為2.0mm~3.0mm的範圍內,比先前的牙刷的頭部薄,因此口腔內操作性提昇。
The minimum thickness of the
另外,頭部10是以如下方式設定:呈格子狀地配置有植毛孔12a,當將頭部10的短邊方向(圖2中的上下方向)的最大寬度設為W1,將多個植毛孔12a的總面積設為S,將頭部10的長邊方向(圖2中的左右方向)上的形成有植毛孔12a的區域的最大長度設為L,將短邊方向上的形成有植毛孔12a的區域的最大寬度設為W2時,分別滿足下式(1)、下式(2)。
In addition, the
6<(S/W1)<9…(1) 6<(S/W1)<9…(1)
3<(L/W2)<5…(2) 3<(L/W2)<5…(2)
再者,長邊方向上的設置有植毛孔12a的區域的長度L是於該長邊方向上配置在最外側的植毛孔12a中的外側的邊緣間的距離。同樣地,短邊方向上的設置有植毛孔12a的區域的最大寬度W2是於該短邊方向上配置在最外側的植毛孔12a中的外側的邊緣間的距離。
In addition, the length L of the area|region provided with the
式(1)表示相對於頭部10的短邊方向的單位長度的長邊方向上的植毛孔12a(毛束11)的長度的適宜範圍(設置毛束11的長度)。若S/W1的值低於下限值,則存在如下的可能性:接觸臼齒的齒頸部的毛束11的量變少而難以充分地洗刷、或頭部10的最大寬度W1大而操作性下降。另一方面,若S/W1的值超過上限值,則存在如下的可能性:頭部10的最大寬度W1變小、或接觸臼齒的齒頸部的毛束11的量於長邊方向上變得過多而操作性變差。
The formula (1) represents an appropriate range of the length of the
相對於此,本實施形態的頭部10因滿足所述式(1)的關係,故牙刷1的操作性不會下降,且適當量的毛束11接觸臼齒,因此亦能夠用力地洗刷齒頸部。
On the other hand, since the
式(2)是表示關於形成有植毛孔12a的區域,相對於短邊方向的單位長度的長邊方向的長度的適宜範圍(配置毛束11的長邊方向的長度的適宜範圍)。若I/W2的值低於下限值,則與式(1)同樣地,存在如下的可能性:形成毛束11的長邊方向的區域變短,當洗刷臼齒的齒頸部時必須增加刷洗(brushing)次數
(頭部10的往返移動次數),或最大寬度W2大而操作性下降。另一方面,若L/W2的值超過上限值,則存在如下的可能性:形成毛束11的長邊方向的區域變長、而操作性變差。
The formula (2) represents an appropriate range of the length in the longitudinal direction with respect to the unit length in the short direction (the appropriate range of the length in the longitudinal direction where the
相對於此,本實施形態的頭部10因滿足所述式(2)的關係,故可避免牙刷1的操作性下降,並且將形成毛束11的長邊方向的區域設定成適當的長度,因此亦能夠以適當的刷洗次數用力地洗刷臼齒的齒頸部。
