- As for insert resin molding, the structure of a molding die is complicated and expensive, so the cost of equipment is high. Further, a work to set a wire to a mold requires time and effort, so it is troublesome. Accordingly, an interdental brush produced by insert resin molding is expensive.
- An object of the present invention is to provide cheap interdental brushes and a producing method capable of producing them.
- An interdental brush according to the present invention comprises: bristles; a wire with which the bristles are twisted; and a handle attached to the wire. The handle consists of a main body and a sub-body. The main body is provided with a longitudinal hole into which a base part of the wire is inserted, and a lateral hole intersecting the longitudinal hole. The base part of the wire is provided with a coming-off preventing bent portion formed to be exposed to the lateral hole. The sub-body is provided with an engagement portion filling the lateral hole so as to surround the periphery of the bent portion.
- According to the interdental brush of this invention, it is possible to produce it by simple resin molding without using insert resin molding. Therefore, cheap interdental brushes are provided.
- Further, if a part of the surface of the main body is covered with the sub-body, and the discrimination properties of the main body and the sub-body are different to each other, it is possible to add visual appeal.
- Further, if the main body and the sub-body are made of synthetic resin, fitting characteristics between resin are high, whereby it is possible to strengthen the bonding power between the main body and the sub-body.
- Further, if a difference in discrimination properties results from at least one of color, gloss and material, the difference in discrimination properties can be changed easily.
- Further, if the main body comprises a shoulder part, a tail part and a barrel part communicating the shoulder part and the tail part via a low step, the lateral hole is positioned in the barrel part, the sub-body covers the barrel part, and the boundaries between the surfaces of the shoulder part and the tail part and the surface of the sub-body adjacent thereto are flush with each other, it is possible to provide a smooth image in the handle as a whole, which contributes to improving the merchantability.
- A method of producing an interdental brush according to the present invention comprises the steps of: forming, by primary resin molding, a main body of a handle having a longitudinal hole and a lateral hole intersecting the longitudinal hole; inserting a base part of a wire, with which bristles are twisted, into the longitudinal hole so as to be exposed to the lateral hole; forming a coming-off preventing bent portion at the base part of the wire via the lateral hole; and forming, by secondary resin molding, a sub-body of the handle such that a part thereof fills the lateral hole so as to surround the periphery of the bent portion.
- According to the method of producing an interdental brush of the present invention, it is possible to produce bristles, a wire and an handle in different steps, which enables to produce an interdental brush in simple steps. Therefore, the cost of producing an interdental brush is low.
- Further, if the step of forming the bent part is performed by inserting a rod-shaped jig J into the lateral hole and pressing the tip part of the jig J onto a to-be-bent portion of the base part of the wire, a part of the role of the jig for forming the bent portion is taken by the main body, and also forming of the bent part itself is easy.
- Further, if the same material is used in the primary resin molding and the secondary resin molding, the material cost can be saved, and also management of the producing steps can be easily carried out. However, different materials may be used in the primary resin molding and in the secondary resin molding.

FIG. 1 is a perspective view of an interdental brush according to the present invention. -
FIG. 2 is a longitudinal sectional view taken along the line II-II ofFIG. 1 . -
FIG. 3 is a longitudinal sectional view taken along the line III-III ofFIG. 1 . -
FIG. 4 is an exploded perspective view showing a twisted wire with bristles of the interdental brush and the main body of a handle. -
FIG. 5 is a producing process drawing of the interdental brush. - Next, an embodiment of the present invention will be explained with reference to the drawings.
- In the explanation below, inside and outside are assumed to mean that, based on FIGS. 1 to 3, the upper side is the front and the lower side is the outside. Further, left and right mean the right side and the left side of
FIG. 2 , and top and bottom mean the left side and the right side ofFIG. 3 , respectively. - Referring to FIGS. 1 to 3, a interdental brush is composed of
nylon bristles 11, astainless wire 12 and ahandle 13 made of thermoplastic synthetic resin. - The
bristles 11 are divided into plural bundles. The bundles of thebristles 11 are held by bundles in between the two-foldedwire 12, which are twisted with thewire 12. Thereby, a twisted wire withbristles 14 having a tip part with the filledbristles 11 and a base part without thebristles 11 is configured. - The
handle 13 consists of amain body 21 and asub-body 22. Themain body 21 and thesub-body 22 are formed by injection molding of polyethylene. Note that themain body 21 and thesub-body 22 may be made of the same material or different materials. As an example of using different materials, themain body 21 may be made of polyethylene, and thesub-body 22 may be made of synthetic resin having rubber characteristics such as EPDM, for example. - As shown in
FIG. 4 in the clearest manner, themain body 21 is in a linear rod shape extending in the inside and outside direction as a whole, and is composed of a substantially inwardconical shoulder part 31, a round rod-shaped barrel part 32, and acylindrical tail part 33. From the inner end of theshoulder part 31, a narrow round rod-shaped neck part 34 is protruded toward the inner side. - At the boundary between the
shoulder part 31 and thebarrel part 32, there is formed ashoulder side step 35 which is lower than theshoulder part 31. At the boundary between thetail part 33 and thebarrel part 32, there is formed atail side step 36 which is lower than thetail part 33. Theshoulder side step 35 is composed of dented U-shapedportions 37 opened to the tail part viewed from the up and down direction, and two protruded reverse U-shapedportions 38 communicating the tips of the bothU-shaped parts 37. Thetail side step 36 is formed of aring part 39 continued around the whole periphery of themain body 21. - A
longitudinal hole 41 is formed from the tip of theneck part 34 up to the inner end of thebarrel part 32 through thebarrel part 32 in the inside and outside direction. The diameter of thelongitudinal hole 41 has a size enabling the twisted wire withbristles 14 to be inserted loosely. Twolateral holes longitudinal hole 41 so as to penetrate thebarrel part 32 in the up and down direction. - At positions outside the two
lateral holes rectangle ridges 44 longitudinal in the inside and outside direction are formed on the both upper and lower side faces of thebarrel part 32, and on both of the left and right side faces of thebarrel part 32,circular protrusions 45 are formed, three for each side, in parallel in the inside and outside direction. - In the
longitudinal hole 41, the base part of the twisted wire withbristles 14 is inserted so as to be exposed to the twolateral holes lateral hole 43 of the base part, a V-shaped bent portion 51 is formed. - The
sub-body 22 is formed so as to cover the whole surface of thebarrel part 32. A part of thesub-body 22 fills the twolateral holes lateral hole 43, the periphery of thebent portion 51 is surrounded by thesub-body 22 which constitutes anengagement portion 52 with respect to thebent portion 51. Further, at theshoulder side step 35 and thetail side step 36, the steps are embedded with thesub-body 22. Thereby, the boundaries between the surfaces of theshoulder part 31 and thetail part 33 and the surface of thesub-body 22 adjacent thereto are flush with each other. Further, the tip parts of theridges 44 and theprotrusions 45 are exposed to the surface of thesub-body 22. - The colors of the resin forming the
main body 21 and thesub-body 22 differs to each other. For example, if themain body 21 is blue and thesub-body 22 is white in color, thehandle 13 is colored with fresh two-tone colors. - Since the
engagement portion 52 is fixed to thebent portion 51, there is no need to worry about the twisted wire withbristles 14 coming off from thehandle 13 at all, even if a tensile force or a torsion force is acted on the twisted wire withbristles 14 when the interdental brush is used. - Next, a method of producing the interdental brush will be explained with reference to
FIG. 5 . First, themain body 21 is made by primary molding. Here, thelongitudinal hole 41 and the lateral holes 42 and 43 are formed at the same time. Next, the base part of the twisted wire withbristles 14, which has been formed by molding separately, is inserted into the lateral holes 42 and 43. Then, a rod-shaped jig J is inserted into the lateral holes 42 and 43, and the tip of the jig J presses a part to be thebent portion 51 of the base part of the twisted wire withbristles 14 so as to deform the part to form thebent portion 51. Finally, after the jig J is removed from the lateral holes 42 and 43, the sub-body 22 is formed by secondary molding. Themain body 21 and the sub-body 22 are fixed to each other, so there is no need to worry about separation.
