FIELD: personal use articles.SUBSTANCE: invention relates to hygienic means and can be used for tooth care. The device contains a body with a floss spool for cleaning interdental spaces. The floss has elastic double-sided conic-shaped bulges. The bulges are positioned with equal spacing. The floss ends are drawn to the outside through a hole in the body whereon an element with a cutting edge for floss cutting and a plate are mounted. The plate is attached to the body with its middle part and has one free part in the form of a cutting element with the blade turned towards the body. The other free part of the plate represents the clamp plate spring with an end deflected away from the body. The plate is attached crosswise to the body over the hole. The body consists of a working part and a cover. The body is designed so that to enable the cover separation through the hole in the tapering top of the body. Shaped in the body working part is a rigid core mating the axial channel in the spool. Made on the cover inner surface is a groove mating the core free end. Made on the body cover is a spring-loaded element preventing the spool rotation.EFFECT: enhanced convenience of the device repeated usage as well as more cost-efficient floss expenditure by way of simplification of the floss placement in the body hole, dosaging of the length of the floss part being cut off as well as more reliable retention of the flow free end on the device.5 cl, 7 dwg |
