| 摘要 |
The present invention provides a sound and/or light emitting toy or novelty device (20) including a portion adapted to be attached on the exterior of a drinking straw (1) and electrical means in the device (24) for emitting a visual and/or audible effect when the portion of the straw on to which the device is fitted is full of liquid. There is provided a pair of electrodes (2,3, Figure 5) which are adapted, when the device is fitted to a drinking straw, to pierce the straw wall at two spaced locations. The visual effects may be generated by light emitting diodes, and the audible effects may be generated by a piezo-electric sounder. Externally, the device may resemble a number of different devices such as a teddy bear (20) or a space vehicle (22, Fig.2). |
