摘要：
The claimed utility model relates to dentistry, in particular to containers for storing dental floss. The claimed cover consists of a lower 1 and upper 2 parts. The lower part 1 has a through tapered hole 3, into which the dental floss (a) is brought out from the container, a ball 4 is installed in the hole 3, which locks the lower outlet of the tapered hole 3, while simultaneously pressing the thread (a) against its inner wall, in fact, performing the role of the brake and the holder for dental floss (a), preventing it from falling into the container (b). The ball 4 is made with the possibility of running in the hole 3 in such a way that when the thread (a) is pulled out of the container (b), the ball rises up, opening the lower outlet of the hole 3, thus freeing up space for the thread to pass. In the upper part of the tapered hole 3, at least one hook 5 is located, which closes the upper outlet of the hole and does not allow the ball to fall out at the time of pulling the thread. The upper part 2 has an opening 6 for the passage of dental floss (a), behind which a knife 7 in the form of a flat pointed metal plate is located inside, for cutting off the measured length of the floss (a). The upper part 2 is attached to the lower part 1 with a flexible loop 8, which prevents the upper part 2 from falling in the open position. Additionally, the upper 2 removable part is designed to protect the dental floss from getting wet and dirty. 3 ill.Заявляемая полезная модель относится к стоматологии, в частности к контейнерам для хранения зубной нити. Заявляемая крышка состоит из нижней 1 и верхней 2 частей. Нижняя часть 1 имеет сквозное конусное отверстие 3, в которое наружу выведена зубная нить (а) из контейнера, в отверстии 3 установлен шарик 4, запирающий нижний выход конусного отверстия 3, одновременно прижимая нить (а) к его внутренней стенке, по сути, выполняя роль тормоза и держателя для зубной нити (а), не дающего ей провалиться в контейнер (б). Шарик 4 выполнен с воз
