【発明の実施の形態】以下本発明の実施の形態を図1〜 1 to the embodiment of the DETAILED DESCRIPTION OF THE INVENTION Hereinafter the present invention
3に基いて説明する。 It will be described with reference to 3.

【0009】10は柄部11の先部に達成された植毛台で、該植毛面10aの対向する長手辺縁部10bに歯ぐきマッサージ用の棒状突起20が適宜数植設されている。 [0009] 10 is a flocked base achieved earlier portion of the handle portion 11, the rod-shaped projection 20 for gum massage the longitudinal edges 10b of opposing plant hair surface 10a is several implanted properly.

【0010】この棒状突起20は、図3(1)に示す如く、植毛台10の植毛面側と背面側の双方で連結したものや、図3(2)に示す如く、1本ずつ独立して植毛台10に組み込んだものであっても良いが、図2に示す如く、植毛台10の背面10c側に於てのみ、各基部20 [0010] The rod-like projections 20, as shown in FIG. 3 (1), and flocking surface side and the concatenation in both the rear side of the bristle base 10, as shown in FIG. 3 (2), independently one by one or may be incorporated in the flocking stage 10 Te but, as shown in FIG. 2, only at hand on the back 10c side of the bristle base 10, the base 20
aを連結部材21を介して相互に連結せしめたものが、 Those ligated to each other via a connecting member 21 a is,
棒状突起20の抜け落ちを防止し得ると共に、棒状突起20間に、植毛台10の植毛面10aが露出し、当該棒状突起20間にも刷毛束を植毛し得るのでより好ましい。 Together may prevent inadvertent rod-like projections 20, between the rod-shaped projection 20, flocked surface 10a of the bristle base 10 is exposed, more preferable because may flocked the brush bundles in between the rod-shaped projection 20.

【0011】この棒状突起20は、重合度100〜2, [0011] The rod-like projections 20, degree of polymerization from 100 to 2,

の例に於ては連結部材21も同材料かつ同システムにて一体成形されている。 Connecting member 21 At a example is also integrally molded with the same material and the same system.

【0012】30は、刷毛束で、棒状突起20間を含む植毛面10aに適宜数植毛されているものである。 [0012] 30 is a brush bundles, are those appropriate number flocking flocking surface 10a comprised between the rod-shaped projection 20. 尚、 still,
刷毛束30の材質としては天然毛、あるいはナイロンやポリブチレンテレフタレート製等の人造毛等その如何を問わない。 Regardless of natural hair or artificial hair such that whether such nylon and polybutylene terephthalate, as the material of the brush bundles 30.

【0013】而して、斯かる歯ブラシは、重合度100 [0013] In Thus, such a toothbrush, the degree of polymerization 100
〜2,000程度の線状シロキサンポリマー(オイル状)を主成分とする液状型シリコーンゴムを材料として用い、液状シリコーンゴム射出成形システムにより、棒状突起20(図2に例に於ては連結部材21を含む)を成形し、次いで0.5〜5分間放置して硬化せしめた後、これを植毛台10に、該植毛台面10a上方に突出するように組み込むことにより、極めて効率的に製造される。 Using a liquid-type silicone rubber as a main component to 2,000 degree of linear siloxane polymers (oily) as a material, the liquid silicone rubber injection molding system, the rod-shaped projection 20 (connection members At a Example 2 molding a containing) 21, and then allowed to after allowed to cure for 0.5 to 5 minutes, the flocking stage 10 this by incorporating to protrude upward plant hair stand face 10a, is manufactured very efficiently that. 因に、当該棒状突起20の植毛台10への組み込みは、刷毛束30の植毛台10への植毛の前後の如何を問わない。 In this connection, the incorporation of the bristle base 10 of the rod-like projections 20 may be either the front and rear of whether the flocking to flocking stage 10 of the brush bundles 30.

【0014】 [0014]

【発明の効果】本発明歯ブラシは、棒状突起が液状シリコーンゴム射出成形システムにより、圧縮成形法に比し低射出圧で成形されているため、バリがなく外観に優れ、しかも加硫剤を必要としないため、該加硫剤や反応副生物による劣化の恐れがない。 The present invention toothbrush according to the present invention is the bar-shaped protrusions liquid silicone rubber injection molding system, because they are molded at a low injection pressure than the compression molding, good appearance without burrs, yet requires a vulcanizing agent since no, there is no risk of deterioration due to the pressurized agent and reaction by-products. また、素練り工程を必要としないため、異物の混入の恐れがなく、より安全性に優れる。 Further, requires no mastication process, without risk of foreign material is excellent in the safety.

【0015】更に、本発明方法によれば、硬化に要する時間も圧縮成形法に比し短いため、自ずと生産性が高く、上記の如き本発明歯ブラシを極めて効率的に製造することができる。 Furthermore, according to the method of the present invention, since a short time required for curing is also compared with the compression molding method, it is possible to naturally high productivity, producing very efficiently the present invention toothbrush such as the above.
