    • A retainer for removably attaching a sheet to a cleaning device. The retainer has at least one cantilevered finger extending inwardly from the periphery of a cavity towards the inside of that cavity. Behind the retainer is a flexible barrier, at least partially covering the back of the cavity. The barrier prevents the user's finger from going too far into the cavity and becoming pinched, and allows the thickness of the device to which the sheet is attached to be reduced compared to a device having a conventional sheet retainer. The barrier may provide visual and/or tactile barrier cues to a user, qualitatively signaling the user which direction is proper for insertion of the sheet into the retainer and quantitatively signally the user how far the sheet should be inserted into the retainer. Strands and/or a membrane panel which are elastic or inelastic may be used for the barrier.
    • 用于将片材可移除地附接到清洁装置的保持器。 保持器具有至少一个悬臂指,从空腔的周边向内延伸到该腔的内部。 保持器后面是柔性屏障,至​​少部分地覆盖空腔的后部。 屏障防止使用者的手指进入空腔中并且被挤压,并且与具有常规片材保持器的装置相比,允许与附接片材相关联的装置的厚度减小。 障碍物可以向用户提供视觉和/或触觉屏障线索,定性地向用户发信号通知哪个方向适合将片材插入到保持器中并且定量地用户信号地将片材插入保持器中。 可以使用具有弹性或非弹性的条和/或膜片作为屏障。
