  • the foreign material is inserted and fixed in the incision It is to be removed.
  • the cutout 111 may have a narrower space between the cutout parts and the first tapered part by a force pressed from the outside. That is, as the pressure that is inserted between the teeth and abuts against the teeth becomes stronger, the gap between the incisions 111 becomes narrower, and the first tapered portion becomes sharper.
  • FIG. 5 is a cross-sectional view of a toothpick according to another embodiment of the present invention.
  • the body part 100 of the present invention includes at least one semicircular protrusion 130 protruding to the outside on an outer circumferential surface, and at least one or more rectangular engaging grooves on the inner circumferential surface of the body part 100 ( 140).
  • the protrusion 130 has a semicircular shape formed on the outer circumferential surface of the body, and in order to prevent the case where the toothpick cannot properly remove foreign matter between the teeth, when the interdental, which is the distance between the teeth, is not constant, the body 100 ) Is formed on the outer circumferential surface. That is, the protrusion 130 formed on the outer circumferential surface of the body 100 is inserted into the interdental at an irregular interdental, and can be removed by pushing or scratching foreign substances that could not be removed. Therefore, it is possible to remove even foreign substances between teeth that have become wider due to tooth imbalance and tooth damage.
  • the locking groove 140 is formed in a structure in which the diameter decreases from the first tapered portion toward the middle point of the body portion 100. This is to form a locking projection 140 for foreign substances to be caught in the opposite direction toward both ends so that the foreign matter inserted into the through hole 110 is not discharged back to the through hole 110 in the direction of the first taper.
  • the locking groove 140 is bent 90° from the inner circumferential surface of the body part 100 toward the outer circumferential surface, and the diameter decreases toward the axis connecting both centers of the through hole, which is the central axis of the body part 100, To have.
  • FIG. 6 to 7 are perspective views of a second tapered portion in the present invention.
  • the body part 100 of the present invention is not converging toward an axis connecting the center of the through hole in a direction in which the first tapered part is not formed, but any of the outer circumferential surfaces of the body part 100 It may include a second tapered portion converging toward an axis corresponding to one point.
  • the second tapered portion is sharply formed to face any one of the outer circumferential surfaces of the body portion 100. Accordingly, the body portion 100 is inserted even between the teeth of very narrow intervals, so that foreign matter between the teeth can be removed.
  • the diameter of the through hole located inside the second tapered part may be different from the diameter of the through hole located in the first tapered part. This is to make the thickness of the second tapered portion thin so that the teeth or foreign substances between the teeth can be scratched and removed.
  • the second tapered portion of the present invention includes at least one cutout 121. This is to remove the foreign material by being inserted and fixed in the cutout 121 when the foreign material cannot be properly inserted into the through hole 110 due to the size problem of the foreign material inserted into the through hole 110.
  • the second taper may include a zigzag cutout 121 having a Z-shape. This too, as described above, due to the problem of the size of the foreign material inserted into the through hole 110, when the foreign material is not properly inserted into the through hole 110, the foreign material is inserted and fixed in the incision part 121 and removed. This is to do.
  • the cutout 121 may have a narrower gap between the cutouts 121 due to a force pressed from the outside, and the first taper may be further tapered. That is, as the pressure that is inserted between the teeth and abuts against the teeth becomes stronger, the gap between the incisions 121 becomes narrower, and the second taper becomes sharper.
  • a spiral wrinkle 150 is formed on the outer circumferential surface of the body portion 100.
  • the wrinkle 150 is a first wrinkle formed between the first tapered portion and the middle of the body portion 100, the second wrinkle formed in the middle of the body portion 100, and between the body portion 100 and the middle of the second tapered portion And a third wrinkle formed.
  • the reason that the wrinkles are formed for each location is that the wrinkles formed on the outer circumferential surface of the body portion 100 inserted between the teeth, which are interdental, can pass by scratching the entire interdental, so that a stronger cleaning effect can be seen.
  • the protrusion 130 described above is preferably formed between the first tapered portion and the first corrugation, and between the second tapered portion and the third corrugation. That is, the first taper portion or the second taper portion is inserted into the interdental to remove foreign substances, and after the wrinkle 150 formed on the outer circumferential surface scratches the entire interdental area, the protrusion 150 scrapes the interdental area wider than the general area. This is to do.
  • the second corrugation of the present invention may include at least one or more openings 155 connected to the through hole of the body portion.
  • the opening 155 is a space for discharging the user's saliva that has penetrated into the opening 155 during the process of cleaning the interdental portion of the body, and the hole may be blocked by the user's saliva, making it difficult to remove foreign substances. This is to prevent.
  • the present invention is a cylindrical body portion 100, extending from one end of the body portion 100 to converge toward the central axis connecting the centers of both ends of the body portion 100 It includes a first taper that is a taper.
  • the body portion 100 may be made of a high-rigidity material of a material that does not bend well to facilitate removal of foreign substances, and may be formed of an elastic material so as not to damage the gums or teeth.
  • the first tapered portion includes a cutout 111 in which a pointed portion is cut. This is for picking up, rather than picking up or pushing the foreign material between the teeth, and removing the foreign material by inserting and fixing the incision.
  • the cutout may have a straight shape and a Z-shaped zigzag shape.
  • the same second tapered portion is formed at the other end of the body portion on which the first tapered portion is formed, and a detailed description thereof will be omitted as it is the same as the first tapered portion.

Abstract

La présente invention concerne un cure-dent qui a un espace prévu à l'intérieur de celui-ci et est destiné à éliminer un matériau étranger entre les dents. Comme un espace est prévu à l'intérieur du cure-dents et qu'une partie de corps absorbe un matériau étranger dans l'espace au lieu de retirer le matériau étranger au moyen de la poussée du matériau étranger vers le côté interne des dents, le matériau étranger peut être retiré, sans avoir à insérer un cure-dent entre les dents au moyen d'une pression forcée et à provoquer ainsi un élargissement entre les dents.
