[Technical field to which the device belongs]

 The present invention relates to a toothpick that prevents damage to the gums when removing foods that are caught between teeth after eating, is easy to carry, and can be used repeatedly.

[0002]

[Prior art]

 As is well known, a commonly-used toothpick (not shown) is configured as an interdental insertion part having a sharp tip and a sharp tip with one end or both ends forming a constant inclination angle. When removing food that remains between teeth using such toothpicks, it is necessary to force the insertion of the interdental part between the teeth (interdental) due to the thickness of the toothpick. As a result, the teeth are shaken, the periodontal tissue is damaged, and the width between the teeth is gradually widened, and more food waste remains, and the end of the interdental insertion part is sharply pointed, so Injuries may cause inflammation, periodontal disease, etc. Most of the toothpicks that are thrown away after use are mixed in the food residue, so the toothpicks with the food residue attached are simply disposed of as waste, which leads to environmental pollution.

By the way, the amount of such toothpicks used has reached several thousand tons (t) annually only in Japan, and it is the fact that some of them are imported from foreign countries. Raw materials produced by the production of these toothpicks. The required amount of trees is said to be tens of thousands of trees aged 10 years or older, which is one of the causes of the destruction of the global environment due to the cutting of timber.

In order to solve the above problems, the “interdental cleaning tool” of Korean Utility Model Publication No. 88-21409 has a handle formed of a deformable elastic material and an upper part thereof. It is an interdental cleaning tool in which a brush in three directions is provided at the center of the axis. However, the process of forming a brush on a thin shaft is not an easy process, and the production process and facility costs are high, so there is a problem that the production cost rises, and it remains around the teeth and gums during use. Foreign substances can be easily removed, but the space between the teeth (interdental) is difficult to use because it is not inserted deeply between the teeth due to the brush formed on the shaft center, and it is also difficult to clean the interdental space once used. removal tool is Ri inevitably foreign material remaining for removal of foreign matter attached between the brush is not easy, even there is a problem on sanitation.

[Means for Solving the Problems]

 The object of the present invention is to solve the above-mentioned conventional problems, and to coat the outer peripheral surface of a linear body formed by spirally twisting a metal wire with synthetic resin to prevent damage to the gums. (EN) A novel toothpick provided by forming a processed interdental insertion part and fixing a grip to the lower part of this interdental insertion part. Further, the present invention also provides a toothpick that is hygienic and convenient to carry and store by covering the toothpick with a detachable lid that is fitted over the toothpick.

[0006]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

As shown in FIG. 1 to FIG. 3, the present invention is an interdental insertion part formed by twisting a metal wire in a spiral shape and covering the entire outer peripheral surface or at least the upper part thereof with a synthetic resin. 10), a grip (20) formed so as to fix and hold a certain length of the interdental insertion part (10), and the grip (20) inserted while covering the interdental insertion part (10). It consists of a removable lid (30).

The interproximal insertion part (10) is bent at its base end to be firmly fixed to the grip (20), and the tip part is formed so that the synthetic resin is covered with a thick curved surface during the covering process. Has been done.

The grip (20) has a slanting surface (21) at one end and a slanting surface (21), and is formed in a cylindrical shape for easy gripping. It can also be formed as a pillar.

The lid (30) is provided with a vent hole (31) at the upper end, and has a hollow cylindrical shape with the lower end opened. It is also possible to form a polygon such as a triangle, a square, or a hexagon according to the shape. Moreover, the inner cross section of the lid (30) is of the same shape as the outer cross section of the grip (20) so that it can be inserted into the grip (20) for alignment. As a modification of the present idea, a clip (30a) may be formed on the outer surface near the top of the lid (30) as shown in FIG. 4 to facilitate carrying the toothpick.

[0011]

[Effect of device]

 In the present invention thus constructed, the iron wire is formed by twisting to maintain a strong elasticity, and the outer peripheral surface of the iron wire is covered with a synthetic resin so that it is hygienically sandwiched between the teeth. It can remove residual food (foreign substances), etc., and can prevent damage to the tooth tissue and gums without straining the space between teeth (interdental space) when removing foreign matter, Since it can be used repeatedly while suppressing the occurrence of diseases, it can be carried and stored for a long period of time. In addition, it is rarely polluted, has good hygiene, and has a great effect from the viewpoint of environmental protection.
