[0131] Then referring to Figure 11 A second embodiment of the toothbrush 1 will be described.

[0132] In this figure, for Figures 1 to 10 The structural elements of the first embodiment of the first embodiment are the same elements, and the same reference numerals are denoted by the same reference numerals.

[0133] In the second embodiment, the bending strength of the deformation portion 70 is different in the thickness direction and the width direction (having anisotropy).

[0134] Figure 11 It is a cross-sectional view of the deformation portion 70 orthogonal to the long axis direction.

[0135] The protruding portion 82 in the toothbrush 1 of the first embodiment is in the long axial direction, and the protruding length protruding from the base 81 is the same circular throughout the week. like Figure 11 As shown, the protruding portion 82 of the present embodiment is formed in the long axial direction of the long axis, and has a long axis in the thickness direction, and has ...

Abstract

The purpose of the present invention is to provide a toothbrush that is gentle on the teeth and gums and that gives useability with a pleasant sensation, while easily preventing overbrushing. This toothbrush comprises: a head part (10) that is provided at a distal end in a longitudinal direction and that has a bristle surface (11); a gripping part (30) disposed further toward a rear end than the head part; a neck part (20) disposed between the bristle surface and the gripping part; and a deformation part (70) that includes a hard section (70H), which is disposed further toward the rear end than the bristle surface and which is formed from a hard resin, and a soft section (70E), which is formed from a soft resin and which coats at least a portion of the hard section. The deformation part is deformed by an external force in a first direction which orthogonally intersects the bristle surface and is compressed as a result of the hard section sandwiching the soft section in the longitudinal direction.

Description

Technical field [0001] The present invention relates to a toothbrush. [0002] The present application claims priority to Japanese Patent Application No. 2019-121416, which is applied in Japan, based on June 28, 2019, and references it here. Background technique [0003] The proportion of people having 20 teeth at 80 years is approximately 50%, on the other hand, the proportion of elderly dental caries (root-side caries) is increasing. Root dental caries is a dental dental caries exposed due to retreat of gums, but since the composition ratio of the organic component is higher than that of the oscillate is higher than that of the enamel, the caries develop is faster. As one of the reasons of the contrast of the gums, excessive brushing of brushing is performed in a brush pressure greater than appropriate value. [0004] Conventionally, as a toothbrush for reducing excessive brush pressure, for example, a toothbrush as described in Patent Document 1 is disclosed. The toothbrush de...
