ORAL CARE IMPLEMENT, HANDLE THEREOF, AND ORAL CARE REFILL HEAD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2021/102612

Kind Code:

A1

Abstract:

An oral care implement (1000) includes a handle (100) and an oral care refill head (200). The oral care refill head (200) is alterable between a first state in which it is separated from the handle (100) and a second state in which it is coupled to the handle (100). The oral care refill head (200) has a proximal edge surface (222) that defines an opening (230) into a sleeve cavity (221). The proximal edge surface (222) is inclined with a radial distance from a cavity axis (B-B) of the sleeve cavity (221). Similarly, the handle (100) has a gripping portion (110) that terminates at a distal end (112) and a stem (120) that protrudes from the distal end (112). The annular shoulder surface (116) is inclined downwardly and away from a stem (120) to facilitate mating of the oral care refill head (200) to the handle (100). The oral care refill head (200) may have features for securing the oral care refill head (200) to the stem (120) of the handle (100).
