Embodiment approach 1

[0022] In the following explanations, the so-called inside and outside are based on Figure 1 to Figure 3 As a reference, the upper side is regarded as the inner side, and the lower side is regarded as the outer side. Furthermore, the so-called left and right are respectively represented by figure 2 The left and right sides are regarded as the left and right, the so-called up and down, respectively image 3 The left and right sides are used as up and down.

[0023] refer to Figure 1 to Figure 3 , The interdental brush is made of nylon bristles 11, stainless steel wire 12 and handle 13 made of thermoplastic synthetic resin.

[0024] The bristles 11 are divided into bundles. Each bundle of bristles 11 is sandwiched between the folded metal wires 12, and then the metal wires 12 are twisted. Thereby, a bristled strand and wire 14 having a front end portion implanted with bristles 11 and a base portion free of bristles 11 is formed.

[0025] The handle 13 is composed of a m...

Abstract

An interdental brush comprising: bristles (11), wires (12) twisted with bristles (11), and a handle (13) mounted on the wires (12), the handle (13) comprising a main body ( 21) and the sub-body (22), the main body (21) is formed with a vertical hole (41) inserted into the base of the wire (12) and a horizontal hole (43) intersecting the vertical hole (41). (12) is formed with anti-off bending portion (51) on the base portion facing the horizontal hole (43), on the sub-body (22) is provided with a circle surrounding the bending portion (51) and filling the horizontal hole (43). ) inside the locking part (52).

Description

technical field [0001] The invention relates to an interdental brush and a manufacturing method thereof. Background technique [0002] As this kind of interdental brush, the following interdental brush is known, which is composed of bristles, a wire twisted with bristles, and a handle provided on the wire, and a curved portion for preventing detachment is formed at the base of the wire. The arrangement of the wires to the shank is realized by their insert resin molding (for example, refer to Japanese Unexamined Application Publication No. 62-174423). [0003] In insert resin molding, the structure of the mold for molding is complicated and expensive, so the equipment cost is high. In addition, the work of setting the wire in the mold is time-consuming and troublesome. Therefore, interdental brushes manufactured by insert resin molding are expensive. [0004] The object of the present invention is to provide an inexpensive interdental brush and a manufacturing method capab...
