Description

A self-locking dental floss stick

technical field

The invention relates to the field of dental floss sticks, in particular to a self-locking dental floss stick.

Background technique

Tooth cleaning has always been one of the focuses of modern people. Toothbrushes, toothpicks, and dental floss are all commonly used tooth cleaning tools. However, flossing has its own unique advantages for removing food debris from between your teeth and keeping your teeth clean.

The most popular flossing tools on the market today mainly include: bow-shaped flossing sticks and dental floss used directly around the fingers. The arched dental floss stick is a one-time product, and multiple arched dental floss sticks may be used to completely clean the teeth, resulting in a great waste of resources, which is not in line with the concept of green environmental protection. For the dental floss that is directly wound around the fingers, the dental floss wrapped around the two fingers must be wasted each time it is used, which greatly wastes resources and shortens the frequency of using a box of dental floss. In addition, using it to clean teeth needs to put hands into the mouth to operate, which is not only inconvenient to use, but also easily causes the harm of disease entering from the mouth. Although some recyclable dental floss sticks have appeared in recent years, there are disadvantages such as complex internal structure and inappropriate operation of the dental floss fixing device group, which limit their wide application.

For the dental floss material itself, the friction coefficient of the currently used nylon material is relatively large, and a large pressure is required to press the dental floss into the interdental gap at the narrow gap between the teeth, which not only damages the enamel, but also easily. Pressing the floss against the gums can cause the gums to bleed and risk infection. And nylon is very easy to absorb water and adhere to the microorganisms in the oral cavity, so generally, after a piece of dental floss is used once, it needs to be replaced with a new dental floss for interdental cleaning.
