Abstract

DC60 (26/05/43) A toothbrush that allows the bristles to penetrate well between the teeth. And address fields The root of the tooth or gums, or the like, that provides a good feeling and cleaning.The toothbrush has bristles that are joined together (1) in place, the bristles are examined together (1), each at the end. Far will have a smooth morphology at The far end in there The far end will Assembled by Separate the far end from the interlocking bristle material at a position 0.5 to 2.0 mm from the tip of the bristles to meet, resulting in a new far end. And end-to-end production New distances of bristles that are joined together to form a part. Far end with smooth morphology on both sides In there, with a smooth surface (2,2), the toothbrush allows the bristles to penetrate well into the interdental cavity. And address fields The root of the tooth or gums, or the like, that provides a good feeling and cleaning.The toothbrush has bristles that are joined together (1) in place, the bristles are examined together (1), each at the end.

Claims (12)

1. A toothbrush consisting of: - tapered bristles (1) each having a distal end that is smooth at its distal end; - such distal end is created by separating the distal end from the tapered bristle material at a position of 0.5 to 2.0 mm from the tip of the tapered bristle material to create a new end and bringing this new distal end into the process of the tapered bristle material to create a smooth distal end. 2. A toothbrush as described in claim 1, where the distal end of each such bristle (1) is set by a pair of smooth surfaces (2,2). 3. The bristles as specified in claim 2, where each pair of smooth surfaces (2,2) therein shall be a straight plane. 4. The toothbrush as specified in claim 2, where each pair of smooth surfaces (2,2) is such that smooth surface is a concave surface. 5. The toothbrush as specified in claim 2, where each pair of smooth surfaces (2,3) therein shall be a convex surface. 6. A toothbrush as specified in any of the claims 2 through 5, where such pair of smooth surfaces (2,2) shall be defined between them as an angle (theta) at the far edge (3) of such far end, where such angle (theta) shall be 5 to 30 degrees. 7. The toothbrush as specified in claim 6, where such angle (theta) will make an angle of 10 to 20 degrees. 8. A toothbrush as described in any of the claims 2 through 7 where the distal end has a thickness (D) of 0.1 mm or less at the distal edge (3). 9. A toothbrush as described in any of the claims 2 through 8, where each pair of smooth surfaces (2,2) is shaped to form a distal edge (3) which is curved and consists of a portion of a circle. 10. A toothbrush as described in any of the claims 2 through 8, where a pair of flat faces each have such shape to form a distal edge (3) which has a curved shape consisting of part of an ellipse. 11. A toothbrush as described in any of the claims 2 through 8, where each pair of smooth surfaces (2,2) has the shape of such as to form the distal edge (3), which is straight. 12. A toothbrush as described in any of the claims 2 through 11, which is further composed of other bristles in sequence that are similarly tapered and combined with the tapered bristles (1) in sequence that are smooth at the distal end.
