DEVICES FOR INDICATING USAGE OF AN ARTICLE

摘要

A device (1, 10) for indicating usage of an article (3) having an elongate handle is provided. The device comprises a rotatable wheel (5, 15), which is divided into a pre-determined number of segments, each of which bears indicia. The wheel (5, 15) has an engaging means (8) for engaging the handle of the article and a stop means (7, 17) for limiting the degree of rotation of the wheel. The device (1, 10) also include a window (6, 16) through which the indicia on a segment can be viewed. When the handle of the article (3) is inserted in the device, the handle co-operates with the engaging means (8) to cause the wheel (5, 15) to rotate by an amount corresponding to one of the segments, the degree of rotation being limited by the stop means. The device (1, 10) is used to display to a user the number of times the article has been used or the number of uses remaining.
