Description

[Detailed Description of the Invention] The present invention relates to a toothbrush that facilitates cleaning of the occlusal surfaces and other details between teeth or molars.

In a toothbrush, bundled fibers are planted upright at one end of the handle, and the bundled fibers are planted upright over a certain range in the length direction and width direction of the handle. Therefore, the tips of the fibers are arranged in a plane in the length and width directions of the handle. Therefore, when brushing, the tips of the fibers hit the surfaces of multiple teeth at the same time, making it possible to brush a wide range at the same time. However, when brushing between the teeth or on the occlusal surface, the tips of the fibers come into contact with the tooth in a line or plane, making it difficult to brush thoroughly between the teeth or in the recesses on the occlusal surface. . There are toothbrushes with fibers cut into slanted edges so that they have a sharp tip, but these also form a line in the width direction of the handle, so it is still difficult to brush the concave portions of the occlusal surface. This proposal is a toothbrush in which four bundles of fibers are planted upright at one end of a rod-shaped handle, and all of the bundles of fibers are tilted toward one point from four tuft holes arranged in an approximately square shape. The fiber bundles were planted upright, and the tips of all the fiber bundles were joined together, and the tips of the joined fiber bundles were made small enough to be inserted between the teeth or into the recess of the occlusal surface. This is the summary.

To explain the toothbrush of the present invention with reference to the embodiment shown in the drawings, 1 is a rod-shaped handle, 2 is a bristle part provided at one end of the handle 1, 3 is 4 bristle holes formed in the bristle part 2, and these are approximately The tuft holes 3 are arranged in a rectangular shape and are slightly inclined in the diagonal direction. Reference numeral 4 denotes bundled fibers planted upright in each flocking hole 3, which are inclined in mutual directions along the slope of the flocking hole 3, and the tips of all the bundled fibers 4 are joined to each other. Bundled fiber 4
As shown in Fig. 2, even if all the lengths are approximately the same and their tips are almost aligned, as shown in Fig. 4, the length of each bundled fiber 4 is changed and their tips are aligned. A step may be added.

This toothbrush is suitable for brushing the details of teeth, such as the inside of the recess on the occlusal surface of molar teeth, the recess between teeth, the space between teeth, the back side of molar teeth, etc. . If the tips of the bundled fibers 4 are inserted into the occlusal area of teeth, the recesses between teeth, or the gaps between teeth, the tips of each bundled fibers 4 can be inserted into each other. Since they are joined to form a single bundle and are small, the bundled fibers 4 can be inserted into recesses or gaps. The back side of the back teeth is
Brushing is performed by inserting the entire bundle of fibers 4 into that area, but since the amount of bundle fibers 4 is small and gathered in one place, the entire bundle can be easily inserted in narrow spaces, and fine parts can also be brushed. Can be brushed accurately.

As mentioned above, the toothbrush of the present invention has its bristle part 2.
This is because the number of bundled fibers 4 planted upright is small, only 4 bundles, and they are slightly inclined in the direction of each other, and their tips are joined to each other, so that the entire tip is gathered into a small size. , small areas such as recesses on the occlusal surface of teeth, spaces between teeth, or gaps between the teeth can be easily brushed. Since each bundled fiber 4 is inclined in the mutual direction and its tips are joined to each other, a small number of bundled fibers 4 support each other, so that the overall waist of the bundled fiber 4 is becomes stronger, and the cleaning effect by the tips of the bundled fibers 4 can be further ensured.

By changing the length of the bundled fibers 4, as shown in Fig. 4,
By forming a step at the tip, it is easy to make the tip of the bonded bundled fibers 4 smaller, making it easier to clean smaller areas. There is no need to limit the shape of the handle 1, but if the flocked part 2 is slightly bent toward the flocked surface side with respect to the grip part as in the example, the use of the bundled fibers 4 will be made easier. is easy. If the flocked part 2 is made into a disk shape as shown in the drawing, it is suitable for easy insertion into a narrow space in the mouth and also for easy movement for brushing, but this is not necessary. be.
