A dental floss device |
摘要 |
A dental floss device 1 comprises a handle 2 having a head piece 3 and a disposable holder 4 for a length of dental floss 5. The holder 4 comprises a base portion 20 and a pair of spaced-apart jaws 21 extending from the base and which extend to embrace the head piece 3 of the handle 2 when the holder 4 is in a correct alignment configuration with respect to the handle 2. The device has an interlock which ensures that the holder 4 can be interengaged with the head piece 3 only when the holder 4 is correctly aligned with the head piece 3. The interlock comprises a head interlock part provided by interlock grooves 10 and a holder interlock part provided by corresponding interlock tongues 11. There are two interlock grooves 10 and corresponding interlock tongues 11 which slidably interengage when the holder 4 is correctly aligned with the head piece 3. If the holder 4 is turned so that it is not correctly aligned with the head piece 3, the interlock tongues 11 of the holder 4 prevent engagement of the holder 4 with the head piece 3. Thus there is no risk that a user will incorrectly align and engage the dental floss holder with the head piece 3.
