Description

  The present invention relates to a toothpick and a toothpick set.

  Conventionally, various proposals have been made regarding toothpick, and among them, toothpick formed in a wood needle shape is widely known. However, when such needle-shaped toothpick is carried and stored in a pocket, wallet or accessory case etc. when not in use, a finger or the like is inadvertently punctured when the toothpick is picked up by hand. Can be hurt.

  In addition, there are generally three scenes where a toothpick is needed within a day, even after meals. Considering other scenes, it is desirable to carry several toothpicks together at a time when going out. It is. However, since the above-mentioned conventional toothpick is bulky when bundled, it is difficult to accommodate it in a pocket or wallet with limited storage space.

  In addition, toothpick used for interdental cleaning should not be exposed in pockets or purses from the viewpoint of hygiene, but if you bring a separate container that only contains toothpick, it will be too bulky. You may be forced to put it in your pocket or wallet. Therefore, it is possible to store the toothpick in a small bag or the like, and make it concealed in a pocket or a wallet. However, in the case of a needle-shaped toothpick, a hole is easily opened at the tip of the toothpick and it becomes unsanitary.

Therefore, many other various toothpicks have been proposed in order to improve the disadvantages of these wood needle-like toothpicks.
