Definitions

  • This invention relates to toothbrush heads and to toothbrushes incorporating such a head.
  • Toothbrushes generally comprise a head and a handle, the head being either an integral part with the handle e.g. integrally moulded of plastic material together with the handle, or replaceably mountable at an end of the handle.
  • the toothbrush head has a face (the "bristle face") on which are mounted bristle filaments, generally made of a relatively stiff fibre material e.g. the commonly used material Nylon, and generally projecting perpendicularly, or at a near-perpendicular angle from the bristle face.
  • a relatively stiff fibre material e.g. the commonly used material Nylon
  • An example of such fibres are those sold under the trademark Tynex TM by Dupont.
  • Toothbrushes are known in which the ends of the bristles are profiled, for example into a point as disclosed in EP-A-0 596 633 into the shape of a flattened blade, e.g. as disclosed in US-A-4, 167,794. Toothbrushes are known which in addition to or as an alternative to such bristle filaments have massage parts mounted on their head. Such massage parts are generally provided for massaging and stimulating the gums, and can also serve other functions such as cleaning and /or polishing the teeth. Often such massage parts are made of an elastomer, i.e. rubbery material and are elongate structures and generally project perpendicularly, or at a near-perpendicular angle from the bristle face, e.g.
  • WO-A-98/03097 discloses massage parts in the form of elastomeric strips with their width oriented across the head.
  • the massage parts are made of soft rubbery material and their function is to gently clean the tooth surfaces and/or to apply a gentle massage to the user's gums.
  • a toothbrush head having a face from which projects at least one projection being elongated in a length direction generally perpendicular to the face and being made of an elastomer material, the projection characterised by; having at its end remote from the head an integral resiliently flexible wiper blade of elastomer material, the wiper blade extending in a length direction generally parallel to the length direction of the projection, the wiper blade having a width direction generally perpendicular to the length direction of the projection and extending in its width direction across at least 50% of the cross section of the projection and having a thickness dimension in a thickness direction perpendicular to its width direction which is 50% or less of its width dimension.
  • the projection comprises an elongated cylindrical or frustro-conical body extending in a length direction from the face of the toothbrush head in a direction generally perpendicular to the face and terminating in an end surface remote from the face, the end surface being substantially planar or shallow convex, and the wiper blade is integrally formed with the body and extends in the length direction of the body from the said end surface.
  • cylindrical and conical used herein include true cylinders and cones, i.e. having circular cross sections and straight sides (tapering in the case of a cone). These terms also include distorted cylindrical and distorted cone shapes, for example having distorted circular, e.g. oval cross sections, or polygonal cross sections, e.g. prism or pyramid shapes, for example with rounded corners. The terms also include shapes with other than longitudinally straight sides, e.g. concave or convex curved sides are also included. The long axis of the cylinder, or the base- apex direction of the cone is the longitudinal direction of the projection as referred to above. If the body is frustro-conical its narrow end is remote from the face. Typical shallow convex shapes for the end surface include for example shallow cone shaped, shallow pyramidal shaped, shallow gable shaped, shallow polyhedral shaped or shallow domed.
  • a typical length for such a body is ca. 0.8 - 1.2 cm, i.e. approximating to the typical length of toothbrush bristles.
  • a typical cross section is ca. 0.5 - 4mm, such as 2 - 4 mm, preferably 3 - 4 mm.
  • a frustro-conical body shape is preferred because such a shape facilitates removal of the projection from an injection mould if the projection is made by injection moulding e.g. of a thermoplastic elastomer ("TPE").
  • TPE thermoplastic elastomer
  • the conical slope of the taper is suitably up to 20°, preferably 10° or less.
  • the end surface of the body remote from the face is planar, e.g. perpendicular to the length direction of the body. If the remote surface is shallow convex then preferably its convex projection is at most 50% of the cross section of the end of the body remote from the face, preferably 25% or less, more preferably 10% or less.
  • the wiper blade is suitably a generally planar blade, with an edge remote from the face, although its thickness direction may deviate from planarity, e.g. by J-_10% , e.g. the thickness dimension may bulge or the blade may be curved in section as cut across its length direction.
  • the greatest dimension ("width") of the wiper blade extends across, preferably entirely across, the end surface of the body, i.e. perpendicular to the length direction of the body, preferably intersecting the central longitudinal axis of the body.
  • the wiper blade has a width dimension parallel to the length direction of the projection which is less than the length direction of the wiper blade parallel to the length direction of the body, and its least dimension being its thickness perpendicular to its length and width.
  • a suitable width: length ratio is in the range 1:3 to 1:20, preferably 1:3 to 1:10.
  • a suitable thickness : width ratio is in the range 0.5 to 0.1, preferably 0.25 - 0.1.
  • the wiper blade may be generally rectangular.
  • the cross section of the wiper cut across its thickness direction may be generally parallel sided, so that the wiper may be of a generally tetragonal shape.
  • Alternative shapes e.g. an arc such as a chord of a circle as viewed in side view perpendicular to the length direction of the body and along the thickness direction of the blade, may also be used.
  • the cross section of the wiper cut across its thickness direction may taper, e.g. being of a wedge shape narrowing away from the face of the toothbrush.
  • the projections may be made of known TPE materials which are known for use for the massage projections of known toothbrushes e.g. as discussed above.
  • Suitable materials are soft elastomeric materials, e.g. having a hardness of less than 90 Shore A.
  • the elastomeric material has a hardness from about 10 to about 90 Shore A, more preferably 50 Shore A or less, e.g. from about 14 to about 35 Shore A.
  • Suitable materials are for example natural rubber, crosslinked polybutadiene, etc., an example of such a material being SantopreneTM.
  • Suitable elastomeric materials include those available under the trade names Megol and Santoprene, and silicone elastomeric materials may also be used.
  • the projections may be made by injection moulding.
  • the projections may be made individually or may be made in groups, e.g. linked by an integrally moulded linker of the elastomeric material.
  • a plastic material skeleton comprising at least the part to become the head of the completed toothbrush may first be made, having locations where one or more projection as described above is to be located in the completed toothbrush.
  • This skeleton may have then be enclosed in a second injection mould cavity having cavity parts defining the shape of the one or more projection to be formed, and then fluid elastomeric material may be injected into the second injection mould, so that the one or more projection is formed as the elastomer sets solid.
  • the conditions of pressure and temperature within the second mould may be such that the elastomer material bonds to the plastic material.
  • the one or more projection(s) of this invention may be positioned at any location on the toothbrush head.
  • one or more projection may for example be arranged along one or more of the sides of the toothbrush head, at the end of the head remote from the handle, or a plurality of the projections may be arranged randomly, in rows oriented across the width of the head (i.e. perpendicular to the head-handle "length" axis) in lines oriented along the length of the head (i.e. parallel to the head - handle axis) in clusters, or otherwise.
  • clusters may for example comprise arrays, e.g. rectangular arrays, or polygonal clusters, and may be located at any place on the head, for example a cluster at the tip end of the head remote from the handle.
  • the wiper blade may be oriented in any orientation relative to the length and width direction of the toothbrush head.
  • the projections may be arranged with their width direction oriented generally parallel to the length direction of the head, or generally perpendicular to the length direction of the head, or at an angle between 0° and 90°, e.g. 45° to the length direction of the head.
  • Two or more of the projections may have their wiper blades oriented differently, for example at 90° to each other.
  • the projections may be combined with bristles of a generally conventional nature.
  • the toothbrush may have the above-described projections arranged around the edges of the head, with bristles extending from the face of the head, i.e. from the central area of the face between the projections.
  • the toothbrush may have the above - mentioned rows, lines and/or clusters of projections combined with rows, lines or clusters of tufts of bristles.
  • rows or lines or groups of rows or lines of the said projections may alternate respectively with rows or lines, or groups of rows or lines of tufts of bristles.
  • the one or more projection may be substantially the same length as the conventional bristles, or alternatively the one or more projection may be longer or shorter than the conventional bristles.
