- these conventional interdental brushes have certain limitations in improving the reachability to details such as the interdental corners of the brush portion and the cleaning effect.
- the present invention intends to provide an interdental brush that can improve the cleaning effect and the detail reachability and can improve the pull-out strength of the filament.
- the present inventor has used a conventional interdental brush with a circular cross-section filament in the brush portion. As a result of finding a certain point and solving this, the present invention has been completed.
- the filament may come off during cleaning, and the site that contributes to the cleaning effect during interdental cleaning is not the tip of the filament like a toothbrush, When inserted between the teeth, it becomes an abdominal part (outer peripheral surface) of the filament that bends and abuts against the interdental part. There is a limit to the action to be taken, and there is a limit to reachability to details. If a thin filament is used, even if it has a circular cross section, the details can be reached. However, the support strength is weak and the cleaning effect is reduced.
- an interdental brush having a brush portion in which a filament is sandwiched between twisted wires and then twisted to twist the wire, and the filament has a polygonal cross-sectional shape.
- the interdental brush is characterized in that at least one internal angle of the polygonal cross-sectional shape is an acute angle of 30 to 75 degrees.
- the “acute angle” includes those in which the inner angle between the sides is an acute angle and the apex portion is slightly rounded.

- the polygonal cross-sectional shape preferably has two or more acute corners.
- the acute angle is preferably 1.2 to 3 times the twist angle of the wire.
- the “twist angle of the wire” is an angle formed by the wire with respect to the axial direction of the brush part to be formed (that is, the insertion direction between the teeth of the brush part), and the filament sandwiched between the wires is at this twist angle. It arranges spirally along.
- the implanted filaments are laminated in two or more rows in the axial direction of the brush portion and are sandwiched between wires.
- the “row” of filaments between wires refers to a row of filaments in which the filaments having the same cross-sectional shape are aligned in the longitudinal direction of the wire, and “laminated state” refers to each of these rows.
- the “axial direction of the brush part” means the insertion and extraction directions of the interdental brush.
- the polygonal cross-sectional shapes of the filaments are laminated in a densely arranged state.
- “Densely arranged state” means that the polygonal cross-sectional shapes of the filaments are densely arranged without gaps, but also includes those having some gaps.
- the polygonal cross-sectional shape of all the filaments planted by the brush part does not necessarily need to be densely arranged, and what is necessary is just a dense state about half or more of the filaments planted. Each filament is sandwiched in a dense and laminated state, so that two adjacent filaments form a substantially parallelogram cross section.
- the cross-sectional shape of the filament is a polygon such as an equilateral triangle, and the sharp angle portion of the polygonal cross-sectional shape is brushed by being sandwiched and twisted between wires.
- each side of the polygon is filled so that the sides thereof are in close contact with each other, and a structure in which the density is increased is possible.
- the cross-sectional shape of the filament is a substantially equilateral triangle, a substantially rhombus, a substantially isosceles triangle, or a substantially parallelogram.
- Can be densified in particular, those having a substantially equilateral triangle are excellent in cleaning effect, have high support strength of filaments, have a high filling rate at the time of arrangement, and can reduce a defect occurrence rate at the time of production.

- Other examples include a disposable type in which the brush base of the brush portion 2 is embedded and fixed in a short shaft handle, and a brush base 2 in which the brush base is embedded and fixed in a short shaft base is attached to and detached from the long shaft holder. It is possible to adopt various forms such as those that are freely mounted, those in which the tip of the long axis holder is bent, and those in which the long axis holder is an electric interdental brush.
- the filament 3 is a monofilament made of synthetic resin, such as polyamide (nylon), polypropylene, polyethylene, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT), a mixture of these resins, and other synthetic resins.

Needless to say, it also includes those having some distortion, such as ridges, swelled slightly on the sides, and dents on the inside.
- the substantially equilateral triangles and rhombuses shown in FIGS. 5 (a) and 5 (b) are more preferable in terms of support strength because they are almost symmetrical with respect to the axial direction 2a of the brush portion 2, and are particularly balanced.
- a substantially regular triangle which is a good regular polygon, has excellent cleaning effect, high packing density, high hair removal strength, low defect occurrence rate during production, and high support strength. It is an example.
- the flat substantially isosceles triangle of FIG. 5C in which the corners 31 and 31 at both ends of the longest side 34 are acute angles is preferable, thereby increasing the packing density.

- the filaments 3 constituting the brush portion 2 do not have to have the same cross-sectional shape, and a plurality of types of filaments having different cross-sectional shapes may be mixed and planted.
- the method of mixing may be mixed at random, but in terms of packing density, it is preferable to plant the same type together in a region.
- the cross-sectional shape of the filament in the flocked region on the wire tip side is approximately rhombus
- the cross-sectional shape of the filament in the flocked region on the base end side is approximately equilateral triangle
- a non-applicable item such as a circle is randomly or divided into regions
