Description

  The present invention relates to an interdental brush for removing dirt such as plaque between teeth.

  As a conventional interdental brush, a brush having a thread portion connected between thread tension portions like the interdental brush shown in FIG. 1 of Patent Document 1 is widely used. The interdental brush of Patent Document 1 is easy to use for cleaning between the teeth on the front teeth side, but for cleaning between the teeth on the back teeth side, the handle portion and the thread portion are parallel, so that the angle between the teeth is angular. Difficult to insert into.

  Therefore, as in the interdental brush shown in FIG. 1 of Patent Document 2, a thread portion arranged in a direction perpendicular to the longitudinal direction of the handle portion is used for cleaning between the back teeth. However, the interdental brush of Patent Document 2 is difficult to use because the handle is operated from the side for cleaning between the teeth on the front teeth side.

Utility Model Registration No. 3110869 JP 2003-93413 A

  As described above, when cleaning the front teeth, use the interdental brush disclosed in Patent Document 1, and when cleaning the back teeth, use two interdental brushes disclosed in Patent Document 2 separately. It was inconvenient because the interdental brush was used alternately.

  Accordingly, an object of the present invention is to provide an interdental brush that can solve the above-described problems and can easily clean the space between the front teeth and the back teeth with one piece.

  An interdental brush according to the present invention for achieving the above object is an interdental brush comprising a main body part having a handle part, and a first thread part and a second thread part arranged on the main body part. The first yarn portion and the second yarn portion are arranged in different directions from each other.

  According to the interdental brush according to the present invention, the first thread portion and the second thread portion are arranged at right angles to the handle portion, so that the first thread portion is cleaned between the teeth on the back teeth side. The second thread portion can be used for cleaning between the teeth on the front teeth side. Therefore, by properly using the first thread portion and the second thread portion, it is possible to easily clean the front teeth to the back teeth without difficulty.

It is a perspective view of an interdental brush. It is a perspective view of the interdental brush of the state turned over. It is a front view of an interdental brush. It is a side view of an interdental brush.

The present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 is a perspective view of an interdental brush, FIG. 2 is a perspective view in an inverted state, FIG. 3 is a front view, and FIG. 4 is a side view. The interdental brush 1 has a length of about 9 cm and a width of about 2.8 cm, and can be prepared and used in suitable sizes for children and adults.

  The interdental brush 1 includes a main body portion 2 and a thread portion 3 disposed on the main body portion 2, and the main body portion 2 is made of, for example, a hard synthetic resin. The thread portion 3 attached to the main body portion 2 is made of, for example, a nylon thread material and has a diameter of about 0.5 mm.

  The thread portion 3 may be a single thread material, or may be a bundle of a plurality of thin thread materials. When a structure is formed in which a large number of thin thread materials are bundled, dirt such as plaque between teeth is easily caught between the thread materials when the gap between the teeth is cleaned, and more dirt can be removed.

  The body part 2 of the interdental brush 1 includes a handle part 4 of a rod-like body whose rear part is a handle part, a protrusion part 5 extending in a horizontal perpendicular direction from the front end part 4a of the handle part 4, and the protrusion It is composed of a pair of arms 6 extending in a curved shape in an obliquely perpendicular direction with respect to the horizontal direction of the protruding portion 5 from the end portion 4a further forward than the portion 5.

  As shown in FIG. 3, when the interdental brush 1 is viewed with the thread portion 3 facing upward, the protruding portion 5 is provided so as to extend from the handle portion 4 to the left side. This is the arrangement of the protrusions 5 of the right-handed interdental brush 1, and for left-handed use, the protrusions 5 may be provided to extend to the right side on the opposite side. Furthermore, the protruding portion 5 may extend from the handle portion 4 in both the left and right directions, and the three yarn portions 3 may be arranged.

  The pair of Y-shaped arms 6 extends in a curved shape in an obliquely vertical direction with respect to the horizontal direction of the protrusion 5 from the end 4 a further forward than the protrusion 5. Furthermore, the arm part 6 is arranged so as to be symmetric with respect to the handle part 4, and is shaped so as to be separated from each other toward the tip.

  The first thread portion 3a is arranged so as to connect the distal end portion 6b of one arm portion 6a and the distal end portion 6d of the other arm portion 6c, and the one arm portion 6a and the distal end portion 5a of the protruding portion 5 The 2nd thread | yarn part 3b is arrange | positioned so that may be connected. The first thread part 3a and the second thread part 3b are fixed to the main body part 2 in a pulled linear state.

  Further, as shown in FIG. 3, when the interdental brush 1 is viewed from the front, the first thread portion 3a is arranged so as to be orthogonal to the longitudinal direction of the handle portion 4, and the second thread portion 3 b is arranged so as to be parallel to the longitudinal direction of the handle 4.

  Accordingly, the first yarn portion 3a and the second yarn portion 3b are arranged at right angles, that is, perpendicular to each other. The first yarn portion 3a and the second yarn portion 3b are not necessarily arranged so as to be orthogonal and parallel to the longitudinal direction of the handle portion 4, and the first yarn portion 3a and the second yarn portion 3b are not necessarily arranged. The yarn portions 3b may be arranged in different directions.

  Further, as shown in FIG. 4, the second thread portion 3 b is arranged so as to be in a diagonal direction perpendicular to the horizontal direction of the protruding portion 5. This oblique direction substantially coincides with the bending direction of the arm portion 6.

  Note that the first yarn portion 3a and the second yarn portion 3b may be connected by a single thread material, connected from the tip portion 5a to the tip portion 6d, and passed through the tip portion 6b. In such a case, it is preferable to provide a groove or hole at the tip 6b and hook the thread material into the groove, or fix the single thread material to the main body 2 through the hole.

  As for the upper and lower teeth in the mouth arranged in a U shape, the teeth on the back teeth side are arranged substantially in parallel with the approaching direction of the interdental brush 1 into the mouth, and the teeth on the front teeth side are arranged substantially vertically. Therefore, when using the interdental brush 1, the back side teeth are cleaned using the first thread portion 3 a disposed substantially perpendicular to the longitudinal direction of the handle portion 4. .

  After the first thread portion 3a is pushed between the teeth on the back teeth side so that the first thread portion 3a is on the bottom, the dirt accumulated between the teeth on the back teeth side can be easily slid up and down. Can be removed.

  Subsequently, when the space between the front teeth is cleaned, the second thread portion 3b is used for cleaning. When a right-handed user inserts the interdental brush 1 into the mouth, the right hand holding the handle 4 is often cleaned at a position to the left of the mouth.

  This is because it is easier for the user to use the interdental brush 1 while tightening the armpits than using the interdental brush 1 with the armpits open. The right hand that naturally grasps the interdental brush 1 is positioned to the left with respect to the mouth.

  In such a case, the second thread part 3b as shown in FIG. 4 is used for cleaning between the teeth on the front teeth side as shown in FIG. 4 rather than the interdental brush in which the thread part shown in Patent Document 1 is parallel to the handle part. It is easier to clean if is slightly slanted.

  That is, by using the second thread part 3b that is disposed obliquely with respect to the insertion direction of the interdental brush that is slanted into the mouth, the second thread part 3b is arranged in a direction orthogonal to the arrangement direction of the teeth on the front tooth side. Will be placed. As a result, the front teeth can be easily cleaned.

  Then, the second thread part 3b is placed downward, and after the second thread part 3b is pushed between the teeth on the front tooth side, it is slid up and down to easily remove dirt accumulated between the teeth. Can be removed.

  The interdental brush 1 is normally disposable from the viewpoint of hygiene, and the entire interdental dirt is removed as described above by the first thread portion 3a and the second thread portion 3b with respect to the teeth arranged vertically. It will be discarded later.

  Thus, by arranging the first thread part 3a and the second thread part 3b at right angles to the handle part 4, the first thread part 3a is used for cleaning between the teeth on the back tooth side, The second thread portion 3b can be used for cleaning between the front teeth. Then, by properly using the first thread part 3a and the second thread part 3b, it becomes possible to clean easily from the front teeth to the back teeth without difficulty.
