Abstract

(57) [Summary] [Problem] To provide a toothpick for cleaning between teeth which has an effect of pushing out a clogged tooth gap. SOLUTION: A tip portion having a length of 5 to 15 mm whose cross-sectional area orthogonal to the axial direction is different from the cross-sectional area of the support portion is cut out from an extended portion of the support portion or fixed to the support portion by bonding.

Description

[Detailed description of the invention]     [0001]   [Technical field to which the invention belongs]   The present invention relates to a toothpick used for cleaning between teeth. It is related to the use of extruding things that are clogged.     [0002]   [Prior art]   Toothpick is used to stab things and remove food clogged between teeth Used for purposes. The shape is a slender columnar shape, as shown in Fig. 7, and the tip is made of a wooden cone. Is common. Also, a plate-shaped product, a triangular pyramid-shaped product, and the like are commercially available.     [0003]   [Problems to be solved by the invention]   Of those described in the prior art, those with a cylindrical shape and a sharp tip at the end are mainly It is used as a substitute for a piercing fork. Flat and triangular pyramids are used for cleaning between teeth.   The flat plate has the effect of pushing out the one clogged between the teeth. However, if the entire toothpick is flat, the tip of the toothpick is If the thickness is reduced, the thickness of the support section will also be reduced, resulting in increased strength such as bending during use. Insufficient convenience due to lack.   The triangular pyramid has sufficient strength without applying any load between teeth, but the cylindrical shape shown in Fig. 7 As in the case where the tip is sharpened conically, the tip is gradually moved from the tip end surface to the support. Since the cross-sectional area increases in each case, it is necessary to insert the tip into the tooth gap It is not possible, and the effect of pushing out the thing clogged between the teeth is weaker than that of a flat plate.     [0004]   [Means for solving the problem]   In order to solve the above-mentioned problem, the inventor of the present invention has proposed a tip portion perpendicular to the axial direction of the toothpick. The area of the cross-section is different from the cross-sectional area of the support portion, and is an area that easily enters between the teeth. In addition, the supporting portion is provided with a cross-sectional area capable of securing strength. The tip is fixed to the support by shaving or joining from the extension of the support.     [0005]   [Embodiment of the invention]   An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a tip, 2 is a support, and 3 is a tip surface. The tip is a rod with a length of 5 to 15 mm. It is cut out from the minute or fixed to the support by joining. In addition, the tip surface may be rounded or chamfered. It is better not to sharpen like the one shown in 7. FIG. 1 shows a case where the tip surface is rounded, FIG. 2 shows a case where the tip surface is chamfered, and FIG. FIG. 3 shows a case where chamfering is not performed. The support part is a part for supporting and operating the toothpick body with fingers, and the cross-sectional shape is optional. Good. 1 to 3 when the cross section is circular, FIG. 4 when it is elliptical, and FIG. 5 when it is square, FIG. 6 shows the case of a hexagon.     [0006]   [Effect of the invention]   The present invention has the following effects. When the cross-sectional area of the tip is narrowed differently from the cross-sectional area of the support, the tip will It has the effect of pushing out the thing clogged between the teeth. Also, by increasing the cross-sectional area of the support section differently from the cross-sectional area of the tip section, Can have any shape and any size. Depending on the cross-sectional shape of the tip, such as a flat plate or triangular pyramid, Since the shape of the surface is not determined, the support part should be Shape can be determined. Further, the strength can be increased by increasing the cross-sectional area of the support portion.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the present invention in which a tip end portion is rounded and a support section has a circular cross section. FIG. 2 is a perspective view of the present invention in which a tip end surface of the tip portion is chamfered and a support section has a circular cross section. FIG. 3 is a perspective view of the present invention in which the cross section of the support portion is circular without chamfering the front end surface of the front end portion. FIG. 4 is a perspective view of the present invention in which the tip surface of the tip portion is rounded and the cross section of the support portion is elliptical. FIG. 5 is a perspective view of the present invention in which the distal end surface of the distal end portion is chamfered and the cross section of the support portion is square. FIG. 6 is a perspective view of the present invention in which the distal end surface of the distal end portion is chamfered and the cross section of the support portion is hexagonal. FIG. 7 is a perspective view of a general toothpick having a cylindrical shape and a tip portion sharpened in a conical shape. [Explanation of reference numerals] 1 {tip 2} support 3} tip

Claims (1)

[Claim 1] A toothpick composed of a tip and a support, wherein the tip is a rod having a length of 5 to 15 mm and is cut out or joined from an extension of the support to support the tooth. A toothpick for cleaning teeth between teeth, wherein an area of a cross section orthogonal to an axial direction of a supporting portion fixed to a portion and in contact with a tip portion is different from an area of a cross section orthogonal to an axial direction of a tip portion in contact with the supporting portion.
