Definitions

  • the invention relates generally to the field of oral care, and in particular to toothbrushes. More specifically, the invention relates to electric toothbrushes.
  • Electric toothbrushes are well known and have been on the market for years. With typical electric brushes all of the tufts of bristles on the brush head are vertically oriented relative to the top surface of the head. The tufts are oscillated, rotated and/or translated in order to provide enhanced tooth cleaning capability.
  • German Gebrauchsmuster 8807968.6 discloses a head for an electric toothbrush.
  • a first group of circular tufts 18 are arrayed in a first ring about the center of rotation of the head.
  • a second group of taller circular tufts 16 are arrayed in a second ring which is outside the first ring and also encircles the center of rotation of the head. All of tufts 16 and 18 are circular in cross-section and are canted away from the center of the head at an acute angle relative to a top surface of the head.
  • a problem with this brush is that all of the tufts have a circular cross-section. Such tufts are not that effective at penetrating between teeth to clean the interdental or approximal areas of the teeth. Further, all but one of the tufts are angled away from the center. Such a tuft pattern tends to flair (flatten) out even more than designed during use, thereby having the same brushing characteristics as a worn-out standard brush. Additionally, none of the tufts are angled along the direction of the rotational circumference which results in even poorer interdental penetration of the bristles.
  • European Patent 0765642 also discloses a head for an electric toothbrush.
  • Bristle tufts 13 , 15 are located about a perimeter of the circular head and are tilted at an acute angle along a circumference of a top surface of the head. All of the tufts on the head have a circular cross-section.
  • a head for an electric toothbrush includes a support member and a plurality of tufts of bristles supported at their base by the support member. Two of the tufts have their bases adjacent to each other and are tilted away from each other at an acute angle relative to the support member.
  • a head for an electric toothbrush includes a support member having a plurality of holes extending completely therethrough.
  • a plurality of tufts of bristles each extends through one of the holes.
  • a first brushing end of each tuft projects from a first side of the support member.
  • Each tuft is prevented from being withdrawn from its hole when a tensile force is applied to the first end of each tuft along a long axis of the tuft.
  • a resilient cushion is positioned adjacent a second side of the support member such that a second end of each tuft can contact the cushion.
  • each tuft When a compressive force is applied to the first end of each tuft along the long axis of each tuft, each tuft can move in its hole in a first direction into the cushion. When the compressive force is removed the cushion causes each tuft to move in its hole in a second direction substantially opposite the first direction.
  • a head for an electric toothbrush includes a support member and a plurality of tufts of bristles supported at their base by the support member.
  • the support member has a substantially circular surface from which the tufts project.
  • a first one of the tufts is tilted along an imaginary radius which projects from a center of the circular surface and passes through a base of the first tuft.
  • a second one of the tufts is tilted along an imaginary circumference which encircles the center of the circular surface and passes through a base of the second tuft.
  • a head for an electric toothbrush includes a support member and a plurality of tufts of bristles supported at their base by the support member A pair of the tufts is tilted in substantially the same direction relative to the support member. A first tuft of the pair has a different cross-section than a second tuft of the pair.

  • an electric toothbrush 10 includes a neck 12 and a head 14 .
  • head 14 is oscillated through an angle of preferably + ⁇ 20 to 50 degrees about an axis parallel to an arrow 3 .
  • Electrical power is preferably supplied by rechargeable or single use batteries.
  • the batteries power an electric motor which, through gearing or another linking element, oscillates the head. Further details as to how the head is oscillated will not be provided as this aspect of the brush is not the focus of the invention.
  • Head 14 contains a large number of tufts of varying lengths, cross-sections and orientations. Although each tuft is shown as a solid mass in the drawings, the tufts are actually each made up of a great mass of individual plastic bristles.
  • the bristles are preferably made of 612 nylon.

  • the tuft is vertically oriented relative to the top surface of the head.
  • Each of tufts 18 are triangular in cross-section with rounded vertexes (tri-oval in shape). These tufts are 6.35 mm in height with a dimension of 2.03 mm from the rounded vertex nearest the center of the head to its opposite side. Tufts 18 also have a dimension of 2.28 mm between the two remaining rounded vertices. Preferably 6 mil filament is used to make the bristles for this tuft. The tuft is vertically oriented relative to the top surface of the head.

  • Cushion 32 can be made of GLS Dynaflex G6703
  • Tufts 40 are supported at their bases by the support member. The lower portions of the tufts are not shown in FIG., 2 but will be described in further detail below.
  • cushion 32 is shown adjacent support member 34 . Only one of the tufts 18 is shown. The non-brushing end of tuft 18 has been melted into a mass 42 . Mass 42 prevents tuft 18 from being withdrawn from its hole when a tensile force is applied to a brushing end 43 of the tuft along a long axis of the tuft.
  • a cylindrically shaped protrusion 44 is provided on cushion 32 and is in contact with mass 42 . At least one protrusion is provided for each tuft on the brush.
  • mass 42 can be captured within support member 34 while the support member is being formed by injection molding (known as hot-tufting). In this case, cushion 32 is not required.
  • member 34 is ultrasonically welded to base member 30 after the tufts are secured to member 34 . As such, catches 36 and openings 38 are eliminated.
  • a head (support member) 50 supports a multiplicity of tufts of bristles.
  • the bristles all have a diameter of about 6 mil.
  • different filament diameters can be used (e.g. 6.0 ⁇ 0.5 mil).
  • a first group of tufts 52 have a round cross-section and extend perpendicular from head 50 .
  • Each tuft includes about 54 bristles per tuft.
  • Tufts 52 rise about 7 mm above the head (the tufts' length) and preferably include bi-filament bristles.
  • Such bristles are coextruded from two different materials, such as nylon 6.12 and nylon 6.10, and bend when exposed to water. All nylons mentioned for this embodiment are preferably polyamid. Further details on such bi-filament bristles can be found in PCT published application WO 98/14092.
  • a second group of tufts 54 are oval in shape (i.e. fin shaped) and also extend perpendicular from head 50 .
  • the filaments of this tuft are extruded from a single material such as nylon 6.12 Tufts 54 rise about 7.4 mm above the head._There are about 108 bristles in each tuft 54 .
  • a third group of tufts 56 are also oval in shape and rise about 7.4 mm above head 50 .
  • Tufts 56 are preferably made of nylon 6.12 with each tuft including about 108 bristles.
  • Tufts 56 are angled away from vertical by about 6 degrees in a radial direction away from the center of the head (see FIG. 8).
  • a fourth group of tufts 58 are round in cross-section and rise about 7.4 mm above head 50 .
  • Such bristles are coextruded from two different materials, such as nylon 6.12 and nylon 6.10, and bend when exposed to water.
  • Each tuft includes about 54 bristles.
  • Tufts 58 are angled away from vertical by about 7.5 degrees in a radial direction away from the center of the head (see FIG. 8).
  • a fifth group of tufts 60 are oval in cross-section and rise about 8.3 mm above head 50 .
  • Tufts 60 are preferably made of nylon 6.12 with each tuft including about 108 bristles.
  • Tufts 60 are angled away from vertical by about 7.5 degrees in a tangential (i.e. circumferential) direction.
  • Each tuft 60 is angled towards its closest neighboring tuft 60 (see FIG. 8) which makes the tufts more stable because the paired tufts support each other during brushing. This also assists in reducing bristle wear for these tufts.
  • a sixth and final group of tufts 62 are round in cross-section and rise about 7.4 mm above head 50 .
  • Tufts 62 are preferably made of nylon 6.12 with each tuft including about 54 bristles.
  • Tufts 62 are angled away from vertical by about 6 degrees in a tangential (i.e. circumferential) direction. Each tuft 62 is angled towards its closest neighboring tuft 62 (see FIG. 5).
  • Endrounding of the bristles is accomplished after they are secured to the head.
  • the angle of tilt away from vertical for applicable tufts is limited to 7.5 degrees in order to obtain the best endrounding.
  • Conventional stapling techniques can be used to secure the single tufts or segments to the head at an angle up to 7.5 degrees. If a tuft angle above 7.5 degrees is desired, an additional degree of freedom is required for the stapling tool (in this case, endrounding will not be as good).
  • Tufts 56 and 60 preferably include blue or green wear indicating bristles which are described in detail in U.S. Pat. No. 4,802,255.
  • Oval shaped tufts 54 , 56 and 60 are actually each made up of two groups of bristles. The oval shape increase the stiffness of these tufts and allows them to penetrate better between teeth than circular tufts. All of the oval shaped tufts have dimensions of about 1.45 mm by 2.9 mm All of the tufts with round cross-sections have a diameter of about 1.5 mm. The diameter of head 50 is about 13.25 mm. In an alternative embodiment, all of the tufts on the head range in length (the rise above the head) between about 6.7 mm to about 8.6 mm.
