Title:
歯間清掃具
Document Type and Number:
Japanese Patent JP7188077
Kind Code:
B2
Abstract:
Provided is an interdental cleaning tool which prevents, when cleaning between teeth, a flexible cleaning portion from being easily peeled due to a tooth or dental calculus being caught by recesses that are left as marks of hold pins during insert molding, and which prevents, even if such peeling does occur, a large amount of peeling and re-peeling from an end part of a peeled portion. A flexible cleaning portion (21) includes a core covering portion (21a) that covers a core base (12), and a plurality of recesses (21c) that are formed due to hold pins during insert molding. The recesses (21c) are formed along a longitudinal direction of the core base portion (12). A core base exposed portion of each recess (21c) has a shape elongated in an oblique direction that intersects both the longitudinal direction and a lateral direction orthogonal to the longitudinal direction, and, at a position where a dimension of the core base exposed portion in the longitudinal direction is maximum, the maximum dimension is 0.25 mm or less.
