Abstract

PURPOSE: To enable an interdental brush to be easily attached in such a manner that the upper part of the main body and that of a sub body are bent, the base of wire with a brush part is inserted into a through hole of a connecting member, an insertion groove formed in the main or sub body and an insertion groove in the lower part of the bent part, and a cap is inserted into the lower end parts of the main and sub members. CONSTITUTION: A main body 10 and a sub body 11 are connected by a connecting member 12. Both ends of the connecting member 12 and the upper ends of the main and sub bodies 10 and 11 are connected by thin members 13 and 14. Bent parts 15 and 16 are formed in the upper parts of the main body 10 and the sub body 11, respectively. An insertion groove 19 is formed in the upper part of the main body 10 and an insertion groove 23 is formed in the upper part of the sub body 11. An insertion groove 27 is communicated with the grooves 19 and 23. The upper ends of the grooves 19 and 23 are communicated with a through hole 18. The inner face of the main body 10 is detached from the inner face of the sub body 11 by rotating the lower end portion 20 of the main body 10. Wire 7 of an interdental brush 6 is inserted into the through hole 18 of the connecting member 12. The lower end of the wire 7 is positioned in the insertion groove 27 of the sub body 11. After that, the main body 10 and the sub body 11 are joined and a cap 28 is inserted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interdental cleaning tool for removing interdental edible pieces and plaque.

[0002]

2. Description of the Related Art A conventional interdental cleaning tool will be described with reference to FIG. FIG. 6 is a partially cut left side view. In FIG. 6, 1 is a vertical rod-shaped metal gripping body, 2 is a support rod having a diameter smaller than that of the gripping body 1, which is integrally formed at the upper end of the gripping body 1. And the tip is slightly inclined rearward. Reference numeral 3 is a threaded groove formed at the tip of the support rod 2, and reference numeral 4 is an insertion hole formed in the support rod 2 at the upper end of the threaded groove 3 in a direction orthogonal to the axial direction of the support rod 2.

Reference numeral 5 is an insertion groove formed in a rear spiral groove 3 in the axial direction of the support rod 2 and having an upper end communicating with the insertion hole 4, and 6 is an interdental brush, for example, a wire having a wire diameter of 0.5 mm. A brush portion 8 to be inserted between the teeth is provided at a tip portion of the wire 7, a base portion of the wire 7 is inserted from the insertion hole 4, and is bent along the insertion groove 5. Reference numeral 9 denotes a nut screwed into the thread groove 3 from the lower part of the support rod 2, and presses the base portion of the wire 7 located in the insertion groove 5 to prevent the interdental brush 6 from escaping.

Next, the mounting of the interdental brush 6 will be described. In a state where the interdental brush 6 is not attached, first, the nut 9 is rotated and moved downward to be positioned below the thread groove 3 of the support rod 2. Next, the wire 7 of the interdental brush 6
The base portion of the wire rod 7 is inserted into the insertion hole 4 of the support rod 2 from the front, the brush portion 8 is obliquely positioned, the base portion of the wire 7 is bent to be along the insertion groove 5, and the base portion of the wire 7 is pressed. To rotate the nut 9 in the reverse direction and move it upward,
To prevent the interdental brush 6 from escaping.

Then, the brush portion 8 of the interdental brush 6 is slowly inserted between the teeth to remove the interdental edible pieces and plaque. Next, when removing the interdental brush 6, the nut 9 is rotated to be positioned below the thread groove 3 of the support rod 2, the wire 7 is extended and pulled out from the insertion hole 4, and the interdental brush 6 is removed.

[0006]

In the case of the above-mentioned interdental cleaning tool, the nut 9 must be rotated and moved upward while the base portion of the wire 7 of the interdental brush 6 is being pressed. Mounting of 6 is complicated. Moreover, since the nut 9 is used, it needs to be made of metal, which causes a problem of high cost.

In view of the above points, an object of the present invention is to provide an interdental cleaning tool which allows easy mounting of an interdental brush and is inexpensive.

[0008]

In order to solve the above-mentioned problems, an interdental cleaning tool of the present invention has a rod-like shape in which an upper end portion is connected to both side edges of a connecting body through a thin portion and inner surfaces are joined to each other. Of the main body and the sub body, a bent portion in which the upper portions of the main body and the sub body are obliquely positioned, an insertion hole that is transparently provided in the connecting body, and an inner surface of at least one of the main body and the sub body. Communication,
An insertion groove formed to a position below the bent portion and a brush portion inserted between the teeth at the tip of the wire are provided, and the base portion of the wire is inserted into the insertion groove from the insertion hole and folded at the bent portion. It is provided with a curved interdental brush and a cap into which the lower ends of the main body and the sub body are inserted.

[0009]

In the interdental cleaning tool of the present invention constructed as described above, the upper ends of the main body and the sub body are connected to both side edges of the connecting body through the thin portions, and the inner surfaces of the main body and the sub body are joined to each other. Then, the upper portions of the main body and the sub body are obliquely positioned by the bent portion, and an insertion groove communicating with the insertion hole of the connecting body is formed on the inner surface of at least one of the main body and the sub body to a position below the bent portion. Then
Since the base portion of the wire of the interdental brush having the brush portion at the tip portion is inserted into the insertion groove from the insertion hole and bent at the bending portion, the lower ends of the main body and the sub body are inserted into the cap. The main body and the subsidiary body are held in a joined state by the cap, and the base portion of the wire of the interdental brush is sufficiently held by the bent portion, so that the interdental brush can be easily attached. Moreover, since the main body, the sub body, the connecting body, and the cap can be molded with resin, the cost is reduced.
