Definitions

  • This invention relates to a toothbrush, and more particularly to a toothbrush capable of exhibiting a high cleaning function sufficient to effectively remove hard to remove dental plaque which tends to readily accumulate at areas such as recesses between teeth, boundaries between teeth and gingivae and the like and capable of feeling soft to the gingivae to a degree sufficient to exhibit excellent usability.
  • the fillings are each formed of a soft material into a thin shape in order to prevent tips of the fillings from damaging gingivae during cleaning by brushing such as the Bass technique or the like.
  • Such fillings feel soft to a user, however, they fail to exhibit rigidity and/or stiffness sufficient to permit dental plaque to be effectively removed, as well as satisfactory durability.
  • a toothbrush of another type which is constructed in such a manner that tips at both ends of each of the fillings are each formed into a tapered shape so as to permit the tips of the fillings to enter or reach areas such as recesses between teeth, boundaries between teeth and gingivae, and the like.
  • a length of the tapered tips of the fillings thus provided is as small as about 1mm, so that the toothbrush fails to significantly improve both a cleaning function and a soft feeling exhibited to a user thereof.
  • the tapered tips of the fillings fail to exhibit advantages over conventional fillings of which the tips are rounded.
  • fillings each having tips formed into a pointed tapered shape of an increased length by chemical treatment are used for various kinds of brushes such as painting brushes, cosmetic brushes, face washing brushes and the like, as taught in Japanese Utility Model Application Laid-Open Publications Nos. 12934/1982 and 65632/1982.
  • fillings of which the tips are each formed into a pointed tapered shape are used in place of conventional fillings exclusively made of natural animal hairs, to thereby improve feeling properties of the brush, its durability, its sanitary properties and the like.
  • the toothbrush including the pointed tapered fillings is substantially inferior in cleaning performance to a conventional toothbrush having non-tapered fillings set thereon, because the tapered fillings are excessively soft or flexible owing to a improper tapered shape.
  • it is required to provide the fillings with suitable hardness by increasing a maximum diameter of the fillings.
  • this causes the pointed tapered tips of the fillings to be so hard to damage gingivae.
  • the present invention has been made in view of the foregoing disadvantage of the prior art.
  • a toothbrush in accordance with a first aspect of the present invention, includes fillings made of a synthetic filament material and a handle provided at a distal end thereof with a filling setting base.
  • Each of the fillings is formed at a tip thereof into a pointed tapered shape and the fillings are tied up into a plurality of bundles.
  • the filling setting base is formed with filling setting holes in which the bundles of the fillings are set so as to permit the pointed tapered tip of each of the fillings to be outwardly projected therefrom.
  • the filling setting holes are arranged in a plurality of rows in parallel to a longitudinal direction of the handle.
  • the pointed tapered tip of each of the fillings is formed with a length of 4 to 8mm
  • a non-tapered section of each of the fillings is formed with a maximum diameter of 0.16 to 0.20mm
  • each of the filling setting holes is formed with a diameter of 1.5 to 2.0mm and spaced from other holes at an interval of 1.0 to 1.2mm in the longitudinal direction of the handle.
  • the pointed tapered tip of each of the fillings may be formed with a length of 4 to 7mm
  • the non-tapered section of each of the fillings is formed with a maximum diameter of 0.17 to 0.18mm
  • each of the filling setting holes may be formed with a diameter of 1.5 to 1.9mm and spaced from other holes at an interval of 1.0 to 1.2mm in the longitudinal direction of the handle.
  • a toothbrush in accordance with a further aspect of the present invention, includes fillings made of a synthetic filament material and handle provided at a distal end thereof with a filling setting base.
  • Each of the fillings is formed at a tip thereof into a tapered shape and the fillings are tied up into a plurality bundles.
  • the filling setting base is formed with filling setting holes in which the bundles of the fillings are set so as to permit the tapered tip of each of the fillings to be outwardly projected therefrom.
  • the filling setting holes are arranged in at least one row parallel to a longitudinal direction of the handle.
  • the tapered tip of each of the fillings is formed into a shape defined by diameters of the tapered tip of the filling at distances of 1mm, 3mm, 5mm and 8mm from a tip end of the filling, the diameters being set in the ranges of 25 to 35%, 55 to 70%, 80 to 90% and 90 to 100% of a diameter of a proximal section of the filling, respectively.
  • the fillings may have a stiffness represented by calculated values from deflection forces at distances of 1mm, 3mm, 5mm and 8mm from the tip ends of said fillings, the calculated values being 0.5 to 2.0N/mm2, 2.5 to 4.5N/mm2, 3.5 to 5.5N/mm2 and 6 to 15N/mm2, respectively, as measured and calculated according to the International Standard ISO 8627.
  • a toothbrush of the illustrated embodiment generally designated at reference numeral 10 in Fig. 1 includes fillings 12.
  • the fillings 12 are made of a synthetic filament material such as polyester, polyamide, polypropylene, other polyolefins, or the like.
  • the fillings 12, as shown in Fig. 2 are each formed at both tips thereof into a pointed tapered shape as indicated at reference numeral 14.
  • Each of the pointed tapered tips 14 has a length of 4 to 8mm, and preferably 4 to 7mm.
  • each of the fillings 12 includes a non-tapered intermediate section or proximal section 16 interposedly arranged between both pointed tapered tips 14.
  • the non-tapered intermediate section 16 is formed into a maximum diameter of 0.16 to 0.20mm, and preferably 0.17 to 0.18mm.
  • the toothbrush also includes a handle 18 made of a suitable synthetic resin material such as polypropylene, AS resin or the like.
  • the handle 18 is provided at a distal end thereof with a filling handle 18 is provided at a distal end thereof with a filling setting base 20 as shown in Figs. 1 and 3.
  • the filling setting base 20 is formed thereon with a plurality of filling setting holes 22.
  • a plurality of the fillings 12 formed as described above are tied up into a plurality of bundles and then each bundle is formed into a U-shape by bending a central portion thereof.
  • the bent central portions of the respective filling bundles are set in the corresponding filling setting holes 22, resulting in the toothbrush being fabricated as shown in Fig. 4.
  • the filling setting holes 22 are each formed into a diameter of 1.5 to 2.0mm, and preferably 1.5 to 1.9mm. Also, the holes 22 are arranged in a plurality of rows in parallel to a longitudinal direction of the handle 18 in such a manner that intervals X between the holes 22 in the longitudinal direction of the handle 18 are set to be 1.0 to 1.2mm. The fillings 12 bundled and bent as described above are set in the holes 22 so that the length Y of each of the fillings 12 is 10 to 12mm as in the conventional toothbrush (Fig. 4).
  • the above-described construction of the present invention was achieved after a number of experiments performed by the inventors. If the pointed tapered tips 14 have a length exceeding 8mm, the rigidity and/or stiffness of the fillings 12 will be reduced to a degree sufficient to cause the cleaning performance of the fillings 12 to be significantly deteriorated, whereas a length less than 4mm causes the fillings 12 to feel unsoft to the gingivae and makes it difficult for the tips 14 of the fillings 12 to enter or reach areas such as recesses formed between teeth, boundaries between teeth and gingivae, and the like, resulting in the fillings 12 failing to exhibit a satisfactory cleaning action.
  • the tips 14 of the fillings stimulate the gingivae, leading to a possibility, depending on the manner of cleaning with the toothbrush, that the gingivae will be damaged; whereas a maximum diameter less than 0.16mm causes the fillings 12 to fail to exhibit rigidity and/or stiffness sufficient to permit the pointed tapered tips 14 of the fillings to exhibit a satisfactory cleaning function.
  • the filling setting holes 22 have a diameter exceeding 2.0mm, the bundles of the fillings will have to be excessively increased in diameter, resulting in it being difficult for the tips 14 of the fillings to reach or enter areas such as recesses between teeth, boundaries between teeth and gingivae, and the like. Also, such a diameter of the holes 22 causes the fillings 12 to feel unsoft to the gingivae. On the other hand, a diameter less than 1.5mm causes a cleaning action of the fillings to deteriorate and the tips 14 of the fillings 12 to be readily deformed or bent into a tulip-like shape, leading to the tips losing their utility.
  • intervals X between filling setting holes 22 in the longitudinal direction of the handle 18 are more than 1.2mm, the bundles of the fillings are decreased in density, so that the cleaning action of the toothbrush is significantly deteriorated.
  • intervals below 1.0mm cause the density of the bundles to be excessively increased, to thereby make it difficult for the tips 14 of the fillings 12 to reach or enter areas such as recesses between teeth, boundaries between teeth and gingivae, and the like and deteriorate the productivity and utility of the toothbrush.
  • Intervals between the filling setting holes 22 in directions other than the longitudinal direction of the handle 18 may be suitable set as in the prior art.
  • the length of the pointed tapered tips 14 of the fillings 12, the maximum diameter of the non-tapered intermediate section 16 of the fillings 12, the diameter of the filling setting holes 22, and the intervals X between the filling setting holes 22 in the longitudinal direction of the handle 18 in the toothbrush of the present invention which are set as described above permit the fillings 12 to exhibit a softness similar to the softness of the hair of such animals as a horse, a goat and the like. Also, the above-described maximum diameter of the non-tapered intermediate section 16 of the fillings 12 which are to be set in each of the filling setting holes 22 permits the fillings set in the holes 22 to exhibit satisfactory rigidity and/or stiffness.
  • the fillings 12 are bundled to have a thickness sufficient to permit the fillings to readily enter areas such as recesses between teeth, boundaries between teeth and gingivae, and the like.
  • the toothbrush of the illustrated embodiment permits dental plaque, which the conventional toothbrush failed to remove, to be effectively removed while also preventing gingivae from being damaged.
  • the fillings 12 are made of a synthetic monofilament such as polyester, polyamide, other polyolefins, or the like.
  • the fillings 12, as shown in Fig. 5, are each formed at both tips thereof into a predetermined pointed tapered shape as indicated by reference numeral 14.
  • Each of the pointed tapered tips 14 is formed into a shape defined by diameters of the tapered tip 14 of the filling 12 at distances of 1mm, 3mm, 5mm and 8mm from a tip end of the filling 12, which diameters are set in the ranges of 25 to 35%, 55 to 70%, 80 to 90% and 90 to 100% of a diameter of the proximal section 16 of the filling 12, respectively.
  • Each of the pointed tapered tips 14 has a length of 8 to 15mm, and preferably 8 to 10mm.
  • a central proximal section 16 of each of the fillings 12 is formed into a maximum diameter of 0.15 to 0.25mm, and preferably 0.17 to 0.20mm.
  • a plurality of the fillings 12 formed as described above are tied up into a plurality of bundles and then each bundle is doubled over at a central portion thereof.
  • the central portions of the respective fillings bundles are set in the corresponding filling setting holes 22, resulting in the toothbrush being fabricated as shown in Fig. 4.
  • the fillings setting holes 22 are each formed into a diameter of 1.5 to 2.2mm, and preferably 1.5 to 1.9mm.
  • the holes 22 are arranged in a plurality of rows, for example 2 to 4 rows, parallel to a longitudinal direction of the handle 18.
  • the intervals X between the holes in the longitudinal direction of the handle 18 are set to be 1.0 to 1.4mm.
  • the length Y of each of the fillings 12 set in the holes 22 as described above is 10 to 13mm as in the conventional toothbrush.
  • Toothbrush specimens shown in Table 1 were prepared for a comparative test of cleaning capability.
  • the toothbrush specimens were made in such a manner that the filling setting holes 22 wherein the fillings with tapered tips are set of the filling setting base 20 provided at the distal end of the handle 18 made of polypropylene each had a diameter of 1.5mm and the intervals X between the filling setting holes 22 in a longitudinal direction of the handle 18 were set to be 1.0mm.
  • toothbrush specimens were tested by the subjects over a total period of time of six weeks, each of the specimens being respectively tested, in an order from specimen A to specimen F, for one week. Also, the degree of removal of dental plaque resulting from use of each of the toothbrush specimens was measured each week.
  • the degree of removal of dental plaque due to use of each of the toothbrush specimens was measured according to the following procedure.
  • the tartar and dental plaque were fully removed from the tooth of each of the subjects and then use of the toothbrush specimens was commenced.
  • the cleaning was interrupted to allow dental plaque to accumulate on the teeth of the subjects.
  • the amount of dental plaque accumulated was measured and then brushing by the toothbrush specimen was carried out to measure the amount of dental plaque remaining on the teeth after brushing again. Then, the difference between the amount of dental plaque before the cleaning on the seventh day and that after the cleaning was divided by the amount of dental plaque obtained before the cleaning, resulting in obtaining degrees of removal of dental plaque by use of each of the toothbrush specimens in the form of percentages.
  • the tooth specimen A achieved a cleaning performance superior to those of the toothbrush specimens E and F wherein fillings were made of a fine filament material, the toothbrush specimens C and D having a conventional "normal" hardness, and the toothbrush B wherein the fillings were tapered along the whole length thereof.
  • This example was carried out to determine at which degree of thickness of the fillings having pointed tapered tips and at which length of the tapered tips gingivae were stimulated (pricked).
  • Toothbrush specimens which included a filling setting base provided at a distal end of a handle as in Example 1 described above and fillings of thermoplastic polyester filament, having tapered tips of different lengths and maximum diameter sections of different thicknesses set in the filling setting base, were prepared and applied to fifteen persons selected as subjects of this experiment for determining at which degree of thickness of the fillings having pointed tapered tips and at which length of the tapered tips gingivae were stimulated. The results were as shown in Table 4.
  • the test was carried out using model jaws of a standard size on which teeth were detachably mounted.
  • the teeth were coated with model dental plaque made by dissolving a water-soluble polymer red coloring matter in water in such a manner that the model dental plaque reached the root of each of the teeth.
  • the coated teeth were mounted on the model jaws and each of the teeth in the same positions as in Table 2 were cleaned ten times by brushing according to the Bass technique using the toothbrush specimens. Thereafter, a position of a gingival edge of the model jaws to which each of the teeth positionally corresponds was marked and then the teeth were removed from the model jaws to evaluate a depth to which the model dental plaque submarginal relating to the gingival edge of each of the teeth was removed. The results were as shown in Table 5.
  • the effect of lengths of the tapered tips on the cleaning capability of the toothbrush varied depending on the thicknesses of the maximum diameter sections. More particularly, when the thickness of the maximum diameter section was 0.20mm, which was most typical, the tapered tips having a length of between 4mm and 8mm had good cleaning capability, while the tapered tips having a length of 10mm or more failed to exhibit good cleaning capability.
  • Tables 4 and 5 indicate that a combination of a thickness of the maximum diameter section between 0.16mm and 0.20mm and a length of the tapered tips between 4mm and 8mm prevents the fillings from stimulating gingivae and permits the fillings to exhibit a satisfactory cleaning effect.
  • This example was carried out to observe the effects of the diameter of the filling setting holes and intervals between the filling setting holes in a longitudinal direction of a handle in a toothbrush including fillings having pointed tapered tips, on a cleaning action of the fillings.
  • toothbrush specimens were prepared which included fillings formed with pointed tapered tips, and filling setting holes provided in four rows in such a manner as shown in Fig. 3, the diameters of the holes and intervals between the holes being different.
  • the fillings were made of a thermoplastic polyester filament material and each one had a length of 11mm, a thickness of a maximum diameter section of 0.18mm, and a tapered tip having a length of 5mm.
  • the same model jaws as used in Example 2 were used and the same procedure as in Example 2 was repeated to evaluate the degree to which model dental plaque submarginal relating to an edge of gingivae was removed. The results were as shown in Table 6.
  • the toothbrush specimens having filling setting holes with diameters of 1.5 to 2.0mm and intervals of 1.0 to 1.2mm arranged between exhibited an excellent cleaning effect so that model dental plaque submarginal relating to an edge of gingivae was effectively removed, the conventional non-taper toothbrush having, by contrast, failed to remove such plaque.
  • intervals between the filling setting holes which were 1.4mm or more or 0.8mm or less failed to permit the fillings to exhibit a satisfactory cleaning effect.
  • the diameter of 1.4mm or less and 2.1mm or more failed to permit the fillings to exhibit a satisfactory cleaning function.
  • the reason why is that the diameter of 1.4mm or less causes the bundled fillings to be excessively reduced in rigidity and/or stiffness so they lose the capability of removing the plaque, whereas the diameter of 2.1mm or more causes a diameter of the bundled fillings to be excessively increased to prevent the tips of the fillings from entering the submarginal recesses.
  • Toothbrush specimens shown in Table 7 were prepared for a comparative test of cleaning capability.
  • the toothbrush specimens were made in such manner that the filling setting holes 22 arranged in four rows had a diameter of 1.6mm and the intervals X between the filling setting holes 22 in a longitudinal direction of the handle 18 were set to be 1.2mm.
  • the fillings 12 made of a synthetic monofilament material each included a proximal section 16 having a diameter of 200 ⁇ m and a length Y of the fillings was 11mm.
  • the tooth specimen I achieved a cleaning performance superior to those of the toothbrush specimens G and H wherein fillings were formed with thicker tapered tips, the toothbrush specimens J and K wherein fillings were formed with thinner tapered tips, and the toothbrush specimen L having fillings with conventional rounded tips.
  • toothbrush specimens as in the table 8 were prepared and applied to fifteen persons selected as subjects for determining by what shape of the pointed tapered tips gingivae were stimulated (pricked). The results were as shown in Table 9.
  • the toothbrush specimens each were moved 20000 cycles with a stroke of 3cm in warm water at a temperature of 35 °C while the fillings thereof being kept in contact with an rough surface of a plate with a load of 500gf. After this operation, the evaluation of the durability of the fillings was carried out by observing the degree of spread of the fillings. The results were as shown in Table 10.
  • toothbrush specimens having fillings made of a polyester resin monofilament material were tested to observe the cleaning capability, stimulus to gingivae and durability of the toothbrush specimens, likewise respectively.
  • the results were as shown in Tables 12, 13 and 14.
  • Tables 12 to 14 indicate that the toothbrush specimen O is more practical and useful than others.
  • each bundle may include substantially 90% ore more of the specified fillings in combination with other fillings of different shapes.
  • the toothbrush having such combination of fillings can achieve or exhibit a considerable cleaning capability and a soft feeling to gingivae.
  • the toothbrush having one or two rows of the filling setting holes arranged in the filling setting base can be effectively used for brushing boundaries between teeth and gingivae according to the Bass technique.
  • the toothbrush of the present invention includes the fillings which are made of a synthetic filament material and of which a length of the pointed tapered ends or tips, a maximum diameter of the non-tapered section, a diameter of the filling setting holes, and intervals between the filling setting holes are defined within specified ranges, respectively.
  • the toothbrush of the present invention includes the fillings of which diameters of the pointed tapered tips at predetermined positions are defined within specified ranges.
