Description

前記芯部を直線状の細長い軸状に構成することが好ましい実施の形態である。
また、前記芯材の先端部を部分球面状に形成し、その基端部の断面積を０．１５ｍｍ²以上に設定することが好ましい実施の形態である。このように構成することで、清掃部の先端部の強度剛性を高めて、歯間に刺し通した清掃部の先端部により、清掃部の挿入側とは反対の歯間の裏側をも効果的に清掃することが可能となる。 In a preferred embodiment, the core portion is formed in a linear and elongated shaft shape.
In addition, in a preferred embodiment, the distal end portion of the core member is formed in a partial spherical shape, and the cross-sectional area of the proximal end portion is set to 0.15 mm ² or more. By configuring in this way, the strength and rigidity of the tip of the cleaning unit is increased, and the back side between the teeth opposite to the insertion side of the cleaning unit is also effective by the tip of the cleaning unit pierced between the teeth. It becomes possible to clean.

持ち手としての合成樹脂製のハンドル基材を設け、前記芯部を前記ハンドル基材の先端部に連設することが好ましい実施の形態である。また、前記ハンドル基材の長さ方向の途中部の外周部にエラストマからなる環状の滑り止め部を形成し、前記ハンドル基材に滑り止め部と清掃用軟質部とを連結するエラストマからなる連結部を設けることが好ましい実施の形態である。このように構成すると、滑り止め部により歯間清掃具の滑りを防止できるので、歯間清掃具のハンドリング性を向上できる。また、歯間清掃具の成形時には、滑り止め部を成形する滑り止め部成形空間にエラストマ材料を一旦貯留して、この滑り止め成形空間から、連結部を成形する複数の供給路を通じて、清掃用軟質部を成形する清掃部成形空間の基部に、その全周にわたって一様となるようにエラストマ材料を供給できるので、清掃用軟質部の成形不良を効果的に防止できる。 In a preferred embodiment, a handle base made of synthetic resin is provided as a handle, and the core portion is connected to the tip of the handle base. In addition, an annular non-slip portion made of an elastomer is formed on the outer peripheral portion of the handle base material in the longitudinal direction, and the handle base material is made of an elastomer that connects the anti-slip portion and the cleaning soft portion. It is a preferred embodiment to provide a portion. If comprised in this way, since the slip of an interdental cleaning tool can be prevented by a slip prevention part, the handleability of an interdental cleaning tool can be improved. Also, when forming the interdental cleaning tool, the elastomer material is temporarily stored in the anti-slip part forming space for forming the anti-slip part, and from this anti-slip forming space, through a plurality of supply paths for forming the connecting part, for cleaning. Since the elastomer material can be supplied to the base portion of the cleaning portion forming space for forming the soft portion so as to be uniform over the entire circumference, it is possible to effectively prevent molding defects in the soft portion for cleaning.

前記ハンドル基材を細長い扁平な棒状に形成し、前記連結部をハンドル基材の幅広な両面の幅方向の中央部に対応させて、該ハンドル基材の長さ方向に沿って形成することも好ましい実施の形態である。この場合には、歯間清掃具の使用時には、親指と人差し指とでハンドル基材の幅広な両面を摘まんで清掃操作できるので、歯間清掃具を保持し易く、しかもハンドル基材の幅広な両面にエラストマからなる連結部が形成されるので、滑り止め部だけでなく連結部においても、保持した指の滑りを防止でき、歯間清掃具のハンドリング性を向上できるので好ましい。
また、前記ハンドル基材は、ハンドル基材本体と、該ハンドル基材本体の先端部に連設した先細基材部とを有し、前記先細基材部はハンドル基材本体の幅方向に湾曲するとともに、先端側へ行くにしたがって幅狭になるとともに薄肉になるように幅方向及び厚さ方向に先細形状に形成されていることが好ましい実施の形態である。 The handle base material may be formed in the shape of an elongated flat bar, and the connecting portion may be formed along the length direction of the handle base material so as to correspond to the center part in the width direction of both wide surfaces of the handle base material. This is a preferred embodiment. In this case, when using the interdental cleaning tool, it is easy to hold the interdental cleaning tool because the handle and the wide fingers of the handle base can be gripped with the thumb and forefinger. Since the connecting portion made of an elastomer is formed on the connecting portion, not only the anti-slip portion but also the connecting portion can prevent the held finger from slipping, and the handling performance of the interdental cleaning tool can be improved.
The handle base material has a handle base material main body and a tapered base material portion connected to a distal end portion of the handle base material main body, and the tapered base material portion is curved in the width direction of the handle base material main body. In addition, it is preferable that the taper is formed in a tapered shape in the width direction and the thickness direction so as to become narrower and thinner as it goes to the tip side.

前記ハンドル基材に合成樹脂材料節減用の凹部又は貫通孔を形成することが好ましい実施の形態である。このように構成することで、基材部の使用材料を節減して、歯間清掃具の製作コストを安くできるとともに、凹部や貫通孔を利用して、歯間清掃具の意匠性を高めたり、包装用ブリスター容器等に対して歯間清掃具を収容するときに、歯間清掃具をブリスター容器に固定したりできるので好ましい。 It is a preferred embodiment for forming a pre-Symbol recesses or through holes for the synthetic resin material savings to the handle substrate. By constructing in this way, the material used for the base material can be saved, and the production cost of the interdental cleaning tool can be reduced, and the design of the interdental cleaning tool can be improved by using the recesses and through holes. When the interdental cleaning tool is accommodated in the packaging blister container or the like, the interdental cleaning tool can be fixed to the blister container, which is preferable.
