- the third embodiment differs from the second embodiment in that a base material is not used for the head portion 331, and the entire head portion 331 from the handle portion 25 is formed as a transparent elastic portion 138. It is composed.
- the material constituting the elastic portion 138 is selected from those common to the elastic portion 134 of the second embodiment, which are suitable for integrally molding the head portion 331 and the handle portion 25.
- a force that can basically exert the same function and effect as in the second embodiment is such that the head part 231 and the handle part 25 are entirely transparent, except for the brush part. Therefore, inconvenience due to the hard material portion hitting the teeth and the like in the oral cavity can be completely prevented.
- the handle portion 25 which is not only easy to manufacture but slightly deforms slightly. This makes it possible to suppress the application of strong irritation to the gums and the like during use.
- the hardness of the soft material forming both the handle portion 25 and the head portion 331 is set to 60 to 90 degrees, preferably about 70 to 80 degrees in a durometer test of the type in IS-K6253 (IS07619). Therefore, a material that is harder than the elastic portion 134 in the first embodiment is used.
- the hardness is set to an appropriate value to prevent the handle portion 25 and the like from being inadvertently deformed during use so that it cannot be operated.
- the handle-side attaching / detaching portion 28 of the handle portion 25 is formed so as to be able to be securely fixed to the main body 11 by integrally forming a hard material or adopting a more reliable fixing method. Is preferred,.
- FIGS. 19 to 21 show a configuration example of the head unit 431 of the fourth embodiment of the toothbrush 10, FIG. 19 is a schematic perspective view seen from the back side of the head, and FIG. 21 is a schematic perspective view as viewed from the front side, and FIG. 21 is an end view taken along line DD in FIG. 20, showing the integral molding of the head portion.
- the fourth embodiment is different from the third embodiment in that the base material is not used for the main body of the handle portion 25 and the head portion 431, but is applied from the handle portion 25 to the main body of the head portion 431.
- the elastic part 142 is transparent.
- the material of the elastic portion 142 is the same as that of the third embodiment.
- the difference between the fourth embodiment and the third embodiment is that, in the fourth embodiment, a flocking base 141 (a hole for flocking) for transplanting the bristles of the brush of the brush portion 55 is used.
- the base portion for providing the 136) is different from the elastic portion 142 in that it is formed of a hard material.
- the inner core 43 is arranged in the molds 144 and 145, the flocking base 141 is formed first, and then the formed flocking base 141 is planted by the protrusions of the inner core 43. After being set so as to be accommodated in the pores 136, it can be formed by molding the material of the elastic portion 142 like a streak on the outside of the flocking base 141.
- a force capable of basically exerting the same operation and effect as in the second embodiment is such that the head portion 431 and the handle portion 25 are entirely transparent and soft except for the flocking base 141. Since it is formed by the same method as in the third embodiment, it is possible to completely prevent inconvenience due to the fact that the hard material portion hits the teeth and the like in the oral cavity.
- the bristles of the brush portion 55 are implanted in the holes of the hard flocked base 141, and the implanted bristles are supported by the hard flocked base 141. Since it is difficult to come off, a tough structure can be realized, and a material that is slightly softer than that of the third embodiment can be selected as the flexible portion in the handle portion 25 or the like.
