Definitions

  • the present invention relates to dental hygiene items and more particularly but not exclusively to dental hygiene items such as brushes, including tooth brushes, floss items and interdental brushes.
  • a manually claspable handle can be further defined as of the manual, non electric variety, wherein the user provides muscle power creating a scrubbing action which transmits through to the working end of the device.
  • the handle can be powered electrically and engineered to create subsonic, sonic or ultrasonic vibrations in the device, or it can provide a mechanised scrubbing action in the device by means of small electric motors, driveshafts and appropriate gearing.
  • All handles that provide either a macro mechanical or a micro-mechanical scrubbing action, whether it be via driveshafts and gearboxes or via sonically induced vibrations or simple mechanically generated vibrations, or sonic or ultrasonic or subsonic vibrations or movements induced by an eccentric weight on a rotating electric motor shaft shall hereafter be referred to as electric handles.
  • Such brushes fall into three types- 1) those which are themselves equipped with usable mini or small handles usually overmoulded or glued or welded to the twisted wire, 2) those with small plastic retention devices which attach to a corresponding receptacle in a larger handle, or 3) those that have a simple twisted wire brush with no inbuilt mini handle or retention device, where such wire directly clips into or attaches to a large toothbrush like handle that has been specifically designed to accept plain interdental brush twisted wire heads, thus saving the cost of overmoulding a handle, or the waste of throwing away the plastic handle every time an interdental brush is used.
  • denture brushes which have their own unique (large) handle and which is permanently attached to and thrown away with the device head.
  • denture brushes which have their own unique (large) handle and which is permanently attached to and thrown away with the device head.
  • single tuft brush heads which often actually may consist of a series of small tufts focused into a tip to give higher cleaning power to specialised areas which also have a permanently attached handle.
  • tongue scrapers that have integrally attached handles.
  • the current invention seeks to resist this force but still allow 8 degrees of rotational freedom so that it can be set in whatever position the operator finds most desirable.
  • a handle of a dental hygiene item including: a handle having a longitudinal axis, and opposite first and second longitudinal end portions;
  • the second end portion including an engagement portion to releaseably engage a head that is to be fixed to the second end portion so that via manipulation of the handle the head can be manipulated by a user to engage the user's teeth, internal mouth surfaces or tongue;
  • the second end portion includes a first longitudinal length and a second longitudinal length, the second longitudinal length tapering towards an end extremity, with the first length having a longitudinally extending external surface and the second length have a longitudinally extending external surface, with the surfaces being joined by a transition surface, the transition surface being tangential to the first surface and tangential to the second surface, with the second surface spaced outwardly from the first surface by no more than 3mm relative to said axis at the transition surface.
  • the two external surfaces are circular in transverse cross-section.
  • the transition surface is joined to the first surface by a first radius, and the transition surface is joined to the second surface by a second radius, wherein the first radius is larger than the second radius.
  • the first radius is between 9mm and 10mm.
  • the first radius is about 9.7mm.
  • the second radius is between 5mm and 6mm.
  • the second radius is about 5.2mm.
  • a handle having a longitudinal axis, and opposite first and second longitudinally opposite end portions
  • said handle includes a bulbous portion adjacent said first end portion, the bulbous portion tapering to said first end portion and towards said second end portion.
  • said handle is hollow and includes an end cap at said first end portion that is removable to enable items to be located internally and stored in said handle.
  • said head is removably attached to said handle.
  • said handle has an external surface
  • said head has an external surface
  • the handle surface being aligned with the head surface so as to provide a smooth transition between the two surfaces.
  • said handle has a longitudinal length that is greater than the longitudinal length of said head.
  • a dental hygiene item including:
  • a handle to be gripped in a user's hand having a body with a longitudinal axis and a longitudinal end portion;
  • attachment portions to secure the handle to the head, the attachment portions including an annular flange surrounding a passage, and a projection to extend inwardly of the passage to engage internally of the flange so that upon longitudinal relative movement between the handle and head towards each other, the projection enters the passage to engage the flange.
  • the head includes said annular flange, and the handle includes said projection.
  • the attachment portions include a shaft projecting inwardly of the passage, and the handle projection includes an internal projection passage within which the shaft is received when the attachment portions are engaged.

  • the body 15 is bulbous and is designed to be gripped in the hand of a user.
  • the body 15 is bulbous so as to have a bulbous portion at the end portion 18 and hollow in manual versions so that it has improved hand grip, and provides storage internally for oral care accessory items such as flosspicks and/or interdental brushes. Access to the interior of the body 15 is via removal of an end cap providing the end portion 17.
  • the handle 1 1 is also hollow so as to avoid the weight and cost of solid plastic and/or
