Definitions

  • the present invention has, for example, the following aspects.
  • the flocking density is 2500 / cm 2 or more (JIS The value (A / B) of the vertical bristle strength A [N / cm 2 ]) / (horizontal bristle strength B [N] measured by the following measurement method) measured according to S 3016 is 40 [1 / cm 2 ] Toothbrush characterized by the above.
  • the sliding body is slid on the bristle bundle under the following sliding conditions (a) to (d), and the maximum load in the sliding direction applied to the sliding body is defined as horizontal bristle strength B.
  • sliding conditions A plurality of cylindrical rod-shaped bodies (made of stainless steel, diameter: 0.5 mm, maximum surface roughness Ra: 0.4 mm) are arranged in parallel with each other at regular intervals (3 mm intervals between the centers of the rod-shaped bodies). Use a sliding body.
  • the sliding body and the flocked surface are arranged in parallel to each other.
  • At least one of the bristle bundles has a bristle bundle diameter of 2.5 mm or more, and [3] at least one of the bristle bundles has a bristle bundle diameter of 3. 0 mm or more,
  • the ratio (A / B) of the vertical bristle strength A to the horizontal bristle strength B in the entire bristle bundle is 40 [1 / cm 2 ] or more, and 45 [1 / cm 2 ] or more. Preferably there is.
  • a / B is 40 [1 / cm 2 ] or more, the flexibility of the bristles is sufficient, the touching feeling of the hair bundle against the gums is improved, or a cleaning feeling is obtained.
  • thin hair and long hair may be used in order to increase the flocking density and increase the flexibility of the hair bundle.
  • the vertical bristle strength A is measured according to JIS S 3016. Specifically, as shown in FIG. 3, all the hair bundles 12a and 12b are trimmed so as to have a length of 7 mm, and the perpendicular to the end face 12c of the hair bundles 12a and 12b formed by the trimming. From the direction, the load body 100 having the pressing surface 101 is brought into contact and pressed at a speed of 10 mm / min to bend the hair bundles 12a and 12b. At that time, the maximum load applied to the load body 100 is measured, and the value obtained by the maximum load / planted area is defined as the vertical fur waist strength A [unit: N / cm 2 ].
  • the flocking density in the flocked region is 2500 / cm 2 or more, preferably 2800 / cm 2 or more, more preferably 3000 / cm 2 or more.
  • the “planting density” is a value obtained by the number of hairs in the planting region / the planting area.
  • the flocking density is preferably 6000 / cm 2 or less, more preferably 5000 / cm 2 or less from the viewpoint of production.
  • the range of the flocking density is preferably 2500 to 6000 / cm 2, more preferably 2800 to 6000 / cm 2 , and still more preferably 3000 to 5000 / cm 2 .
  • the vicinity of the center of the head portion in the short direction (center portion) is within a range of ⁇ 2 mm from the center of the head portion in the short direction, and when it gradually decreases, the shortest hair length among all the hair bundles Is preferably at least 60% or more with respect to the longest hair length, preferably 80 to 95%. If it is 60% or less, the fit and the contact feeling are lowered.
  • a central hair bundle group located at approximately the center in the short direction of the head part;
  • An outer hair bundle group composed of two or more hair bundles planted across the central hair bundle group in the short direction of the head portion;
  • the flocking density is 2500 / cm 2 or more and 4500 / cm 2 or less,
  • the value (A / B) of (vertical bristle strength A [N / cm 2 ] measured according to JIS S 3016] / (horizontal bristle strength B [N] measured by the following measurement method) is 40 [1 / cm 2 ] or more and 60 [1 / cm 2 ] or less,
  • the hair bundle diameter of the outer hair bundle group is 2.8 mm or more and 3.5 mm or less,
  • the thickness of the outer hair bundle group is 4-7 mils,

Abstract

La présente invention concerne une brosse à dents (1) comprenant un corps de manche (1a), dont l'extrémité comporte une section tête (10). Des faisceaux de soies (12a, 12b) sont implantés, avec une densité d'au moins 2 500 soies par centimètre carré, dans une surface d'implantation de soies (11) sur la section tête (10). Le quotient (A/B) de la rigidité perpendiculaire (A) des soies en newtons par centimètre carré et de la rigidité horizontale (B) des soies en newtons par centimètre carré est supérieur ou égal à 40 cm−2. La présente invention permet d'obtenir une brosse à dents comportant des pointes de soie très souples, comportant des faisceaux de soies produisant un effet agréable contre les gencives, et donnant une forte sensation de propreté.
