Definitions

  • the present invention relates generally to a toothbrush having needle-shaped bristle, and in particular, to a toothbrush tufted with 13 to 18 mm long needle-shaped bristles tapered only on one end, and a manufacturing method thereof.
  • FIG. 2 another traditional toothbrush is made by folding needle-shaped bristles, which are 28 to 33 mm long and tapered 4 to 8 mm on both ends, in two equal halves and planting them in the above-described manner.
  • This toothbrush manufacturing technique is disclosed in Japanese Patent Open-Laid No. Hei 5-15834.
  • the above objects are achieved by a toothbrush tufted with needle-shaped bristles.
  • the bristles are formed of polyester resin.
  • the bristles are 0.1 to 0.2 mm thick before tapering, 13 to 18 mm long, tapered 4 to 8 mm only on one end with a tapered tip thickness of 0.01 to 0.08 mm, and planted to be 7 to 13 mm high in the toothbrush.
  • FIG. 1A is a side view of a folded 23 to 33 mm long bristle which is needle-shaped on one end and non-needle-shaped on the other end, before planting;
  • FIG. 1B is a partial enlarged view of bristles as illustrated in FIG. 1A planted in a toothbrush head;
  • FIG. 2 is a side view of a folded 28 to 33 mm long bristle which is tapered 4 to 8 mm on both ends like needles, before planting;
  • FIG. 3 is a schematic view illustrating a toothbrush tufted with ordinary both-end tapered bristles and 1 to 10 mm longer ones;
  • FIG. 4 is a plan view of a traditional bristle planting pattern for a toothbrush
  • FIG. 5 is a side view of a needle-shaped bristle tapered only on one end according to the present invention.
  • FIG. 6 is a perspective view of needle-shaped bristles as illustrated in FIG. 5 vertically loaded in a cylindrical container;
  • FIG. 7 is a side sectional view of a primary bristle holder for use in manufacturing a toothbrush according to the present invention.
  • FIG. 8 is a side sectional view of a secondary bristle holder for use in manufacturing the toothbrush according to the present invention.
  • FIG. 9 is a side sectional view of a head insert for use in manufacturing the toothbrush according to the present invention.
  • FIG. 10 is a side sectional view of a pusher having inserting poles matching through holes formed in the primary bristle holder;
  • FIG. 11 is a view illustrating transfer of the needle-shaped bristles from the primary bristle holder to the secondary bristle holder and the head insert;
  • FIG. 12 is a view illustrating thermal fusion of the needle-shaped bristles to the head insert
  • FIG. 13 is a perspective view of a toothbrush handle before the head insert is attached
  • FIG. 14 is a perspective view of the toothbrush tufted with the bristles tapered only one end;
  • FIG. 15 is a view illustrating attachment of the head insert to the toothbrush handle by injection molding.
  • FIG. 16 is a view illustrating partial thermal fusion of the bristles.
  • a toothbrush according to the present invention is comprised of one-end tapered bristles formed of polyester resin to be 13 to 18 mm in total length and 4 to 8 mm in tapered length.
  • the non-tapered portions of the bristles are pushed down into through holes arranged in a planting pattern in a bristle holder.
  • the bottom of the bristle holder is thermally fused to thereby fix the bristles to the bristle holder.
  • the bristle holder is then attached to the head of the toothbrush.
  • FIG. 5 is a side view of a single needle-shaped bristle 60 13 to 18 mm in length and 4 to 8 mm in tapered length according to the present invention.
  • the bristle 60 is tapered only on one end and shorter by half with the same tapered length. The one-end tapering diminishes a bristle failure rate involved with tapering.
  • the bristle 60 Since the bristle 60 is planted 5 to 6 mm deep in a toothbrush head, it is then 7 to 13 mm high from the surface of the toothbrush head.
  • the tapered tip of the bristle 60 is 0.01 to 0.08 mm thick.
  • the tapered tip thickness is preferably 0.01 to 0.03 mm to allow the bristles to reach deep between teeth and into gum pockets, and 0.03 to 0.08 mm for thorough cleansing. Both features can be obtained by planting the two types of bristles in combination, or grinding bristles by means of a mesh paper (i.e. sandpaper) after planting, which will be described later.
  • polyester resin specifically PET (Polyethylene Terephthalate) or PBT (Polybuthylene Terephthalate) resin. It is because other materials such as Nylon, acryl, and PP (Polypropylene) resin are inferior in terms of water resistance, durability, and strength, and bristles formed of such a material are entangled when they are immersed in a strong acid or alkaline solution, for tapering. Thus, processing is difficult.
  • PET Polyethylene Terephthalate
  • PBT Polybuthylene Terephthalate
  • FIG. 6 is a view illustrating the bristles 60 loaded vertically in a cylindrical plastic container 61 .
  • the loaded bristles 60 are held in a primary bristle holder 20 as illustrated in FIG. 7, transferred to a secondary bristle holder 30 as illustrated in FIG. 8, and then transferred to a head insert 50 as illustrated in FIG. 9.
  • the primary bristle holder 20 , the secondary bristle holder 30 , and the head insert 50 include through holes 21 of the same shape.
  • the primary and secondary bristle holders 20 and 30 are formed of a metal, whereas the head insert 50 is preferably formed of plastic though a metal can be used.
  • the primary and secondary bristle holders 20 and 30 function to transfer the bristles 60 to the head insert 50 , they are of a metal due to its excellent durability.
  • the head insert 50 is formed of plastic because it is attached to a toothbrush body 70 , with the bristles 60 planted therein.
  • the bristles 60 are held in the primary bristle holder 20 by pushing the bristles 60 into the primary bristle holder 20 with a pusher 40 having inserting poles 41 matching the through holes 21 of the primary bristle holder 20 , as illustrated in FIG. 10.
  • the bristles 60 are then transferred from the primary bristle holder 20 to the head insert 50 through the secondary bristle holder 30 by pushing the bristles 60 held in the primary bristle holder 20 to the secondary bristle holder 30 and then the head insert 50 with the pusher 40 , while matching the through holes 21 , in alignment, of the primary and secondary bristle holders 20 and 30 and the head insert 50 .
  • the non-tapered portions n of the bristles 60 are upward.
  • the bristles 60 protruding from the head insert 50 are thermally fused, thereby being fixed firmly to the head insert 50 .
  • the length of the bristles 60 is controllable to some extent. That is, short bristles 60 are thermally fused while they are protruded to a short length, for example, 1 mm or less, and long bristles 60 , while they are protruded to a long length, for example, about 3 mm. In the case of very long bristles, they are thermally fused in the above manner and then their tips are cut, followed by grinding with a mesh paper. Therefore, an available length range for the one-end tapered bristles 60 is widened.
  • the bristles differ in length after planting, the tips of longer ones are cut and ground by a mesh paper.
  • the length and tip thickness of the bristles are controlled.
  • bristles having a tip thickness of 0.01 to 0.03 mm coexist with ones having a tip thickness of 0.03 to 0.08 mm.
  • the bristles reach deeper between teeth and into gum pockets and clean the surfaces of the teeth thoroughly.
  • the bristles can be planted such that they differ in length by 1 to 10 mm. That is, the planting of long bristles and short bristles with a 1 to 10 mm length difference makes the longer ones reach further between teeth or into gum pockets.
  • the head insert 50 having the bristles 60 fixed thereto is attached to the head of the toothbrush body 70 by an adhesive, ultrasonic bonding or high frequency bonding.
  • a head insert opening 51 is preferably formed in the head of the toothbrush body 70 , so that the head insert 50 can be mounted in the head insert opening 51 , as illustrated in FIG. 13.
  • the thus-completed toothbrush is illustrated in FIG. 14.
  • FIG. 15 An alternative way of fixing the head insert 50 with the bristles 60 to the toothbrush body 70 is, as illustrated in FIG. 15, to combine a lower metal mold 90 to an upper metal mold 80 with the bottom of the head insert 50 fixed thereto, injecting resin into the lower metal mold 90 through an inlet 91 , so that the head and handle of the toothbrush are integrally formed and at the same time, the head insert 50 is tightly combined with the toothbrush head.
  • This fixing method advantageously enables manufacture of various types of toothbrushes using metal molds for the toothbrush head and handle of different shapes, increases process efficiency, prevents introduction of foreign materials due to formation of no junction gaps, and makes it possible to reduce the thickness of the toothbrush head, thus allowing easy thorough teeth brushing.
  • Another way of planting the bristles 60 in a toothbrush body is that the non-tapered portions of the bristles 60 are inserted into through holes in the lower metal mold 90 , protruding 2 to 5 mm from the metal mold 90 , these protrusions are thermally fused, an upper metal mold (not shown) is combined with the lower metal mold 90 , and then resin is injected so that the bristles 60 are attached directly to the toothbrush body, as illustrated in FIG. 16.
  • This method also offers the benefits that the toothbrush head is integrated into the toothbrush handle, product yield is increased, no junction gaps are produced to thereby prevent introduction of foreign materials, and reduces the thickness of the toothbrush head.
  • the toothbrush according to the present invention is tufted with needle-shaped bristles tapered only on one end, as compared to the traditional toothbrush having both-end tapered bristles. Therefore, an inferior goods rate is remarkably dropped and thus product cost can be reduced by 30% or more.
  • a bristle planting pattern and the number of the needle-shaped bristles can be freely controlled, thereby enabling the bristles to clean away hard-to-reach plague.
  • the use of thermal fusion instead of a cut wire leads to tighter fixing of the bristles. Even needle-shaped bristles which are failed in length control can be utilized for fabrication of the toothbrush.
