TOOTHBRUSH WITH NEEDLE-SHAPED BRISTLES FOR IMPROVING TOOTH AND GUM CONTACTING FORCE AND TEETH-CLEANING PERFORMANCE, AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2011/014000

Kind Code:

A2

Abstract:

The present invention relates to a toothbrush with needle-shaped bristles positioned in the head of the toothbrush, wherein the difference in height between the longer bristles and the shorter bristles is 1 to 4 mm, the longer bristles have an end point with a diameter of 0.01 to 0.03 mm, the shorter bristles have an end point with a diameter of 0.03 to 0.08 mm, the longer bristles have a tapered length of 4 to 8 mm, the shorter bristles have a tapered length of 2 to 6 mm, and the difference between the tapered length of the longer bristles and the tapered length of the shorter bristles is 1 to 4 mm. The toothbrush of the present invention maintains superior tooth and gum contacting force, which is unique to a toothbrush having needle-shaped bristles, and the end point of the shorter bristles has a relatively larger diameter and the tapered length of the shorter bristles is short, thus improving teeth cleaning performance. In addition, the shorter bristles contribute to retarding the abrasion at ends of the bristles, thereby lengthening the lifespan of the toothbrush.
