A refill head, and oral care implement incorporating the same, wherein the refill head can be uncoupled from a stem of a handle by withdrawing the refill head from the stem of a handle along the longitudinal axis of the oral care implement, which results in locking members on the refill head disengaging from an engagement rib on the stem. The locking members and engagement rib may be aligned with or angled relative to the longitudinal axis of the oral care implement. A portion of the stem may be visible through a portion of the refill head to reinforce the proper connection between the refill head and the handle.一種重填頭以及與該重填頭結合的口腔保健器具,其中,藉由沿口腔保健器具的軸線自一手柄之桿拉出重填頭,造成重填頭上之鎖定構件脫離桿上的接合肋,使可自該手柄之桿拆卸重填頭。鎖定構件與接合肋可相對於口腔保健器具互相對齊或形成角度。經由一部份的重填頭可見到一部份之桿,以使再加強重填頭與手柄之間的正確接合。50‧‧‧動力牙刷60‧‧‧縱向軸100‧‧‧重填頭110‧‧‧頭部111‧‧‧牙齒清潔元件120‧‧‧套筒123‧‧‧內部表面124‧‧‧外部表面127‧‧‧上部部位210‧‧‧握緊部220‧‧‧桿222‧‧‧外部表面226‧‧‧遠側末端230‧‧‧抗轉肋234‧‧‧開口236‧‧‧頂部
