INTERDENTAL BRUSH
Document Type and Number:
WIPO Patent Application WO/2018/025304
Kind Code:
A1
Abstract:
An interdental brush is provided which can be easily inserted between the teeth. This interdental brush has a handle part 10, a core part 20, and a brush part 30. The core part 20 extends in a straight line from the handle part 10. The brush part 30 is formed from multiple filaments which extend from the core part 20 in a direction that intersects the direction of extension of the core part 20. The brush part 30 includes n filament bundles (n being an integer greater than or equal to 3) which are formed from single groups of filaments continuous along the direction of extension of the core part 20. The interval between the filament bundle 33 nearest the tip 20a of the core part 20 and the adjacent filament bundle is wider than the average interval of the n filament bundles.
