摘要： Disclosed are a toothbrush and a method of producing the same. The toothbrush of the present invention includes a pressure relief unit (r) which is installed in a head part of the toothbrush and has a plate shape and a predetermined size sufficient to cover bristles set in the head part. In the present invention, the head part is thin, and the bristles are set in the head part without using a wire. Furthermore, the present invention is easily adapted for mass production using inexpensive equipment. As well, the pressure relief unit (r), which is installed in the head part, serves as a reinforcing unit. Therefore, the head part is prevented from breaking during use despite having a reduced thickness.

摘要： The present invention relates to a method of tapering a toothbrush bristle which increases production efficiency. The method includes the steps of cutting bundles of toothbrush bristles; and non-directionally immersing the entire cut bundles of toothbrush bristles into a chemical solution to taper both sides of the toothbrush bristles. According to the present invention, the production efficiency of a needle-shaped bristle is increased approximately three times, and the loss of raw materials is greatly decreased because several processes are not performed.

摘要： The present invention provides a needle-shaped bristle and a method of manufacturing the needle-shaped bristle. The manufacturing method of the present invention includes the steps of cutting and removing a packing sheet, which is wound around a bundle of bristles, by a length ranging from 30 mm to 50 mm from a first end thereof, and grinding first ends of the bristles using a rotating grinder. The manufacturing method further includes steps of packing the first end of the bundle of bristles, from which the packing sheet is removed, using a packing sheet, cutting the bundle of bristles to a length ranging from 22 mm to 32 mm, and immersing a second end of the cut bundle of bristles, thus tapering second ends of the bristles. The needle-shaped bristle has an advantage of realizing a reduction in the proportion of defective products.

摘要： The present invention provides a method of manufacturing a toothbrush with needle-shaped bristles. The method includes the step of setting needle-shaped bristles, partially tapered by being immersed in a chemical, in a head part of a toothbrush body. The method further includes the step of grinding the needle-shape bristles using a drum grinder having protrusions (10) such that end points of the bristles range from 0.01 to 0.03mm in thickness and tapered portions of the bristles range from 3.5 to 8mm in length. A toothbrush, in which needle-shaped bristles having end points of 0.03 to 0.05mm in thickness and tapered portions of 3.5 to 10mm in length are set, can be manufactured using the method of the present invention. In the present invention, because a manufacturing process is simplified, the required production time and a defective proportion are markedly reduced.
