Embodiment Construction

[0046] Next, the toothbrush to which the present invention is applied will be described in detail with reference to the drawings.

[0047] In addition, in order to make the characteristics easier to understand, in the drawings used in the following description, some characteristic parts may be schematically shown for convenience, and the dimensional ratio of each component is not necessarily the same as the actual one. . In addition, the illustration of the hair bundle is omitted depending on the case.

[0048] As an embodiment of the present invention, figure 1 The toothbrush 1 shown has a brush handle 1A that is long in shape as a whole. neck4.

[0049] The handle 1A is composed of a handle 2, a neck 4 connected to the handle, and a head 3 connected to the neck, for example, integrally formed of a hard resin material. As the hard resin material used on the handle 1A, for example, polypropylene, polyethylene, polyethylene terephthalate, polycyclohexene dimethylene terephtha...

Abstract

A toothbrush in which bristle holding holes (7) are formed in a bristle holding surface (3a) of a head (3), bristle bundles (6A, 6B) are each two-folded, and a flat plate (8) sandwiched between the two-folded portions of the bristle bundle (6A, 6B) is driven into a bristle holding hole (7) to embed the bristle bundles (6A, 6B) into the bristle holding holes (7). Bristle bundles (6A, 6B), each having one side (6a, 6c) and the other side (6b, 6d) which are located with the flat plate (8) present therebetween and have a difference in height therebetween, are embedded in at least some or all of the bristle holding holes (7) formed in the bristle holding surface (3a). The directions of the flat plates (8) of the bristle bundles (6A, 6B) are appropriately set so that the tips of the bristle bundles (6A, 6B) form an undulation.

Description

technical field [0001] The present invention relates to a toothbrush in which a three-dimensional undulating shape is given to the tip of a bristle bundle without cutting the bristle shape, which has a high degree of design freedom and is easy to manufacture. [0002] this application claims priority based on Japanese Patent Application No. 2007-335415 for which it applied on December 27, 2007, and uses the content here. Background technique [0003] The basic functions of the toothbrush include cleaning effect and massage effect in the oral cavity. In order to improve the basic functions of toothbrushes, toothbrushes have added interdental penetration, clean feeling, massage properties, etc. compared with conventional toothbrushes. Furthermore, in order to achieve high added value of such a toothbrush, it is generally effective to combine the arrangement and shape of the tufting holes, the type and shape of the bristles, the cut shape of the bristle bundles, and the like i...
