    • A refill head for an oral care implement, such as a toothbrush, wherein the refill head utilizes a specially designed structure for coupling the refill head to an oral care implement handle that ensures proper alignment and simplifies the loading and unloading of the refill head to the oral care implement handle. In one embodiment, the refill head comprises a tubular sleeve forming a cavity and first and second upper cam surfaces that form shoulders within the cavity. The first and second upper cam surfaces are separated by first and second axial slots of different configurations that prevent loading of the refill head onto the oral care implement handle in an improper rotational orientation through interaction with first and second bosses on the oral care implement handle.
    • 用于口腔护理器具的补充头,例如牙刷,其中所述补充头使用特别设计的结构,用于将所述补充头连接到口腔护理器具手柄,所述口腔护理器具手柄确保正确的对准并且简化了所述补充头的装载和卸载到 口腔护理器具手柄。 在一个实施例中,补充头包括形成空腔的管状套筒和在空腔内形成肩部的第一和第二上凸轮表面。 第一和第二上凸轮表面由不同构型的第一和第二轴向槽分离,从而防止通过与口腔护理器具手柄上的第一和第二凸起相互作用,以不正确的旋转取向将填充头装载到口腔护理器具上。

    • An oral care implement, such as a toothbrush, which includes a handle and a replacement head utilizing a specially designed structure for coupling the replacement head to the handle of the oral care implement. The replacement head comprises a head and a tubular sleeve comprising a cavity for receiving a handle. A protuberance protrudes radially inward from an inner surface of the tubular sleeve for engaging a boss of a stem on the handle to impede rotation of the tubular sleeve about the stem in a first angular direction. A locking tab protrudes radially inward from the inner surface of the tubular sleeve for engaging an undercut surface of the boss to prevent axial disengagement of the tubular sleeve from the stem. The locking tab is circumferentially spaced from the protuberance so that an first axial channel exists therebetween for receiving a section of the boss.
    • 一种口腔护理器具,例如牙刷,其包括手柄和使用专门设计的结构的替换头,用于将替换头连接到口腔护理器具的手柄。 替换头包括头部和管状套筒,其包括用于接收手柄的腔体。 凸起从管状套筒的内表面径向向内突出,用于接合手柄上的杆的凸台以阻止管状套筒绕第一角度方向旋转。 锁定突出部从管状套筒的内表面径向向内突出,用于接合凸起的底切表面,以防止管状套筒与杆的轴向脱离接合。 锁定突舌与凸起周向间隔开,使得其间存在第一轴向通道,用于接收凸台的一部分。
