Description

ABSTRACT:
A dental flosser which has a locking mechanism that effectively prevents slippage of floss string during use. Broadly speaking, the flosser includes a body and a handle threadably joined to the body. The locking mechanism includes a bore in the body through which the floss is threaded, a shoulder on the body, and a washer mounted on the body adjacent the bore. With the floss looped around the washer, threadably tightening the handle on the body compresses the floss between the shoulder and handle to prevent floss slippage. Preferably, the handle has a floss storage cavity and the body has an internal floss passageway extending to the tip of one of two prongs on the body. Loosening the handle allows floss to be drawn or dispensed from the one prong.
