Embodiment Construction

[0039] Next, a toothbrush according to one embodiment of the present invention will be described with reference to the accompanying drawings.

[0040] Figure 1A and Figure 1B The toothbrush 1 shown has a handle body. The handle body has: a substantially rectangular head 5 when viewed from above; The handle portion 2 has: a handle portion 3 ; and a neck portion 4 formed between the handle portion 3 and the head portion 5 . Roughly rectangular is a concept that includes a shape whose top is chamfered by a straight line or a curved line.

[0041] One surface of the head 5 is a flocking surface 52 , and two or more flocking holes 54 are formed on the flocking surface 52 . The hair-planted surface 52 is a surface on which a hair-planted part is formed by planting two or more bristle bundles in the hair-planting hole 54 . exist Figure 1A and Figure 1B In , the illustration of the hair bundle is omitted.

[0042] The other face of the head 5 is made into a tongue coating des...

Abstract

Provided is a toothbrush with which a brushing pressure may be detected with ease by a user, and the oral cavity of the user may be cleaned at an appropriate brushing pressure. The present invention comprises a head portion, and a handle portion which is extended from the head portion, a hair bundle being disposed at a hair implant surface of the head portion. At the handle portion of the toothbrush, a projecting section which protrudes to a back side of the hair implant surface of the toothbrush is disposed, and a tubular enclosing section is disposed to surround the projecting section. A tip of the projecting section protrudes from the tubular enclosing section. The tubular enclosing section may be displaced relatively in a direction of the tip when the tip and a tip side of the handle portion are at a fixed position, and the head portion is weighted from the hair implant surface.

Description

technical field [0001] The present invention relates to a toothbrush. [0002] This application claims priority based on Japanese Patent Application No. 2011-184568 for which it applied in Japan on August 26, 2011, and uses the content here. Background technique [0003] When cleaning the inside of the oral cavity with a toothbrush, it is important to apply moderate pressure to the target site with the hair-implanted part and brush it. About 200 g of pressure (washing pressure) applied to the target site by the hair transplanting part is appropriate. [0004] Generally, when cleaning the inside of the oral cavity, it is difficult to recognize the scrubbing pressure, and cleaning is often performed with an excessive scrubbing pressure or with an excessively low scrubbing pressure. If the brushing pressure is too low, it is difficult to remove the plaque, especially the plaque in the small parts such as the interdental part and the neck of the tooth. If the brushing pressure...
