Abstract: An oral care implement (1000) that 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) by inserting a stem (120) of the handle (100) inside of a cavity (221) of the oral care refill head (200). The oral care refill head (200) has at least one alignment groove (250, 260) that receives at least one alignment rib of the stem (120) of the handle (100). Furthermore, the stem (120) and the oral care refill head (200) include snap lock features that form a snap-fit interlock to secure the oral care refill head (200) to the handle (100).

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