Problems solved by technology

[0006] However, in any cylindrical toothbrush, there is a problem that there is a gap between the radial blades of the adjacent spherical brush elements, so that the radial blades are easily tilted in the axial direction. Decreased descaling, massaging effect of brushing during shorter periods of use
In addition, the density of flocking in the axial direction of the handle is reduced, thereby reducing the massage effect

Embodiment Construction

[0049] Embodiments of the present invention will be described below.

[0050] The cylindrical toothbrush of the 1st embodiment is as Figure 1 ~ Figure 3 As shown, it is composed of a round rod-shaped handle 10 that is reciprocally operated along the central axis direction by holding it with one hand, and a cylindrical brush head 20 mounted on the front end portion of the handle 10 . The handle 10 is composed of a main body portion 10A held by hand, and a head holding portion 10B detachably attached to the front end side thereof.

[0051] The main body portion 10A of the handle 10 is basically a cylindrical shape with a diameter that is easy to hold. However, in order to further improve the ease of holding, the portion other than the front end is arranged on four surfaces at intervals of 90 degrees in the circumferential direction. Odd-shaped octagonal cross-section with chamfering. In order to realize the connection with the head holding part 10B, the screw 11 protrudes tow...

Abstract

A circular tubular toothbrush having bristles implanted with an appropriate implant density distribution in the direction of the axis of a handle. The structure allows a user to comfortably use the toothbrush and provides the toothbrush with excellent massage performance in addition to excellent brushing performance. A circular tubular brush head (20) provided to the front end of a handle (10) has a hybrid structure in which hard round brush elements (20A) and soft round brush elements (20B) are arranged in the axial direction in a mixed state. The hard round brush elements (20A) each consist of a large number of nylon threads used for the bristles of toothbrushes and are each formed as a thin radial blade in which the nylon threads project radially outward. The soft round brush elements (20B) are each formed as an integral part consisting of an SEBS resin used for toothpicks etc. and each have a petaline shape in which tongue-shaped planar projections project radially outward.

Description

technical field [0001] The present invention relates to a cylindrical toothbrush, wherein a cylindrical and radial brush head is concentrically mounted on the front end of a rod-shaped handle that can be held by one hand and reciprocated along the central axis. Background technique [0002] In recent years, as a kind of toothbrush, a kind of cylindrical toothbrush has been disclosed in patent documents 1 and 2, wherein the front end of the rod-shaped handle that can be held by one hand and reciprocated along the central axis is concentric. A cylindrical brush head is installed, which is also attracting attention in the market. Here, the cylindrical brush head is formed such that radial spherical brush elements made of bundles of filaments (usually nylon filaments) forming the brush portion of the toothbrush overlap along the central axis. [0003] The individual spherical brush elements are manufactured continuously by opening the strands of wire at the periphery, welding t...
