Problems solved by technology

[0003] However, in this interdental cleaner, although the synthetic resin hair-like bodies are sandwiched between the metal wires, the metal wires are sometimes bent during use. In addition, the hair-like bodies are sandwiched by twisting the metal wires, so , the fixing force of the trichomes on the metal wire, that is, the tensile strength of the trichomes is sometimes uneven
In addition, when using metal wires to make interdental cleaners, the metal wires must be bent into a U-shape, hair-like bodies are arranged between the bent pieces, and then the bent pieces

Example Embodiment

[0064] Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

[0065] figure 1 It is a front view of main parts of an embodiment of the interdental cleaning tool of the present invention. figure 2 Yes figure 1 The enlarged cross-sectional view of line II-II. image 3 It is the overall front view.

[0066] Interdental cleaning is provided with a number of hairy protrusions 2... and a handle 4 of a predetermined length. The hair-like protrusions 2 are made of melted synthetic resin as a raw material, and are integrally formed on the outer peripheral surface of the shaft body 1 at intervals in the circumferential direction and the axial length direction. The handle 4 is integrally formed on the base of the shaft body 1 described above.

[0067] The shaft body 1 has the same shape from the base to the front end, and is formed in a cylindrical shape with a diameter of 0.5 mm, for example. In addition, it may be forme...

Abstract

Relates to an interdental cleaning tool provided on the peripheral surface of a shaft member 1 with one or a plurality of projections 2, the projections being pinnulate elements or cirrate elements, and shaft member 1 and projections 2 being integrally molded from synthetic resin, whereby there may be afforded a soft touch against the tissues of the oral cavity during use, deviation in extraction force of the pinnulate members and cirrate members may be prevented, and production costs may be reduced.

Description

technical field [0001] The invention relates to a interdental cleaning tool which is inserted into the gap between adjacent teeth to clean the gap and its manufacturing method. Background technique [0002] Conventionally, interdental cleaners that are inserted into the gap between adjacent teeth to clean the gap are as follows. That is, a metal wire is bent into a U-shape at the center of its length direction, a number of hair-like bodies made of synthetic resin are arranged between the formed bent pieces, one end and the other end of the bent piece are pinched, and the bent piece is bent. After the flap is twisted to sandwich the hair-like body, the end of the hair-like body is cut off, the lengths of the hair-like body are aligned, and one end of the above-mentioned metal wire is attached to a handle of predetermined length made of synthetic resin. [0003] However, in this interdental cleaner, although the synthetic resin hair-like bodies are sandwiched between the meta...
