Abstract

PROBLEM TO BE SOLVED: To obtain a tooth pick which damages neither teeth nor a gum by making at least a part containing the tip part of a cone part flat in the tooth pick having the cone part following a cylinder part to facilitate the insertion thereof into a clearance between the tooth while enabling accurate griping thereof. SOLUTION: In a tooth pick having a cone part 2 following a cylinder part 1, a flat part 3 is formed at least at a part containing the tip part of the cone part 2. In a making method, a bar material is cut into a cylinder and one end thereof is cut into a cone to form a cylinder part 1 and a cone part 2. Then, a part containing the tip part of the cone part 2 is cut flat from both sides to form a flat part 3. In the tooth pick thus obtained, the gripping of the cylinder part assures the gripping and the flat part at the tip part facilitates insertion into a narrow clearance between teeth thereby minimizing damage to the teeth and a gum.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothpick, and more particularly, to a shape of a tip of the toothpick and a method of manufacturing the toothpick.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional toothpick has a cylindrical portion 1 which is gripped by hand and a conical portion 2 which is formed continuously with the cylindrical portion 1 and is inserted into a gap between teeth to remove foreign matter. Is formed. In addition, as shown in FIG. 5, there is one that is formed in a flat shape over the entire length.

[0003]

When the conventional toothpick shown in FIG. 4 is used to forcibly insert the conical portion 2 of the toothpick into a narrow gap between the teeth and remove foreign matter, the root of the conical portion becomes thick. Because it is meat, it is difficult to insert it into the gap between the teeth, and if you insert it forcibly, extra force will be applied to the tooth, not only damage the root of the tooth but also damage the gums,
It was undesirable for dental health. In the case shown in FIG. 5, the whole was flat and thin, and not only could it not be reliably gripped, but also the toothpick itself had insufficient strength and foreign matter could not be sufficiently removed. Then, this invention was made in order to solve such a problem of such a conventional toothpick, and can be firmly grasped, can be easily inserted into a gap between teeth, and does not damage teeth and gums. Offers a toothpick.

[0004]

A toothpick according to the present invention is a toothpick having a cylindrical portion and a conical portion formed continuously with the columnar portion, at least a part including a tip portion of the conical portion is formed in a flat shape. Things.

[0005] A method for manufacturing a toothpick according to the present invention includes a step of forming a cylindrical portion of a rod-shaped member, a step of forming a conical portion at one end of the cylindrical portion continuously with the cylindrical portion, and a tip portion of the conical portion. The method includes a step of forming at least a part in a flat shape.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1 1 is a plan view and a side view showing a first embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a cylindrical portion of a toothpick, 2 denotes a conical portion of a toothpick, and 3 denotes a part including a tip of the conical portion 2. It is a formed flat part.

Next, the manufacturing method of the first embodiment will be described. First, a bar (not shown) is cut into a cylindrical shape as shown in FIG. 2A, and one end thereof is cut into a conical shape as shown in FIG. 2B to form a cylindrical portion 1 and a conical portion 2. Then (c)
As shown in (1), a part (here, approximately half) including the tip of the conical part 2 is cut flat from both sides to form a flat part 3. In the manufacturing method of the first embodiment, a flat portion shaving step may be added to the conventional final manufacturing process of a toothpick, and a significant modification of the manufacturing process is not required.

[0008] The toothpick thus configured grips the cylindrical portion, so that it is securely gripped. Further, since the toothpick has a flat portion at the tip, it can be easily inserted into a narrow gap between the teeth. Less damage to teeth and gums.

Embodiment 2 In the first embodiment, the flat portion 3 is formed almost in half including the tip of the conical portion 2, but in the second embodiment, as shown in FIG. Formed. The structure shown in the second embodiment is suitable for removing a foreign substance clogged deeply in a place where the gap between teeth is particularly narrow (many artificial teeth) because the flat portion becomes long. The manufacturing method according to the second embodiment is the same as that according to the first embodiment, and a description thereof will not be repeated.

[0010]

According to the toothpick according to the present invention, a flat portion is formed on a part or almost all including a cylindrical portion serving as a grip portion and a tip portion of a conical portion formed continuously with the cylindrical portion. In addition to being secure, it can be easily inserted into the narrow gap between the teeth, and the teeth and gums are less likely to be damaged. In addition, the method for manufacturing a toothpick according to the present invention can be achieved by adding a flattening step to the conventional manufacturing process of a toothpick, and does not require a significant modification of the manufacturing process.
