Definitions

  • This invention relates generally to teeth-whitening appliances using an air- dried varnish or gel, and more specifically concerns a varnish/gel cartridge in combination with a brush or a reusable applicator or brush.
  • Teeth whitening has become an increasingly popular dental treatment and various specific treatment appliances and/or methods are known. Many of these treatments, which use peroxide for teeth whitening, are used only by a dental professional. Appliances which use a peroxide formulation and are designed for safe home use typically are not as effective for teeth whitening, due to a decreased level of peroxide in the formulation.
  • Teeth-whitening gels and varnishes which are air-dryable, are currently typically applied by syringes or pen-like devices.
  • the applicator tip becomes hard after a single use and is hence inefficient and usually too expensive for successive treatments.
  • the varnish container is also often too large for convenient hand use.
  • a tooth-whitening varnish or gel cartridge and an applicator brush comprising: a single-use cartridge reservoir containing a tooth-whitening formulation which dries in exposed air; and a brush adapted for fluid contact with the reservoir in the cartridge to receive the formulation from the reservoir and to apply the formulation to the teeth of a user.
  • a teeth-whitening appliance comprising: a reservoir adapted to contain multiple uses of an air-dryable teeth-whitening formulation; and a brush applicator removable from the reservoir, wherein the reservoir includes an end which is adapted to receive replacement brush applicators.
  • Figure 1 is a perspective view showing a combined cartridge and applicator brush in a pen-like applicator appliance.
  • Figure 2 is a perspective view showing a pen appliance with cartridge and brush being used to spread teeth-whitening formulation, such as varnish, on teeth.
  • Figure 3 is a perspective view of a cartridge/brush combination capable of being used by itself.
  • Figures 4A and 4B are perspective views of the reservoir for a teeth-whitening formulation in a cartridge/brush combination.
  • Figure 5 is an exploded view of an applicator which includes a reservoir containing a plurality of treatments, a disposable brush and a cap.
  • Figure 6 is an exploded view showing details of the brush and cap portions of
  • Figure 7 is an exploded view of a dosing system with a reusable applicator.
  • the present invention concerns the combination of a teeth-whitening formulation, in the form of an air dryable varnish or gel provided in a cartridge reservoir, with a brush for convenient user application of the formulation.
  • the brush can be integrated with the cartridge as well as being arranged and adapted to be used in a pen-like applicator appliance in one embodiment.
  • the combination can be in the form of a single use or multiple uses with replaceable brush elements, or a stand-alone balloon applicator device.
  • Figure 1 shows a cartridge and brush combination 10, with a brush element 12 and a cartridge 14 having a reservoir with a teeth-whitening formulation 16 therein.
  • the brush/cartridge combination 10 is shown in Figure 1 inserted into one end of a pen-like appliance member 18 for hand use.
  • the pen is shown with brush and varnish in one cartridge
  • the brush is a conventional nylon brush having flexible nylon bristles or similar material, approximately 10 mm long at its longest dimension.
  • the brush will typically end in a line 20 and will angle from one edge to an opposing edge for convenient application. A straight edge can be used, or a rounded edge as well.
  • the cartridge portion can take various configurations, but must match the configuration of the end of the pen member 18 for holding the cartridge and have an upper end for receiving the brush portion of the combination.
  • a single use cartridge will have 1-2 ml of formulation.
  • Figure 2 shows a particular pen appliance assembly 24 into which the brush/cartridge combination is fitted. This appliance with a hand grip portion 25 can be conveniently used by a dentist or other dental professional.
  • the cartridge can include a syringe-like element which can be operated on, i.e. pushed, by a portion of the appliance. This element can be used to break the seal for the formulation reservoir in the cartridge.
  • the appliance can also be arranged so that the seal is broken when the brush is fitted into the cartridge.
  • Figure 3 shows a stand-alone combination including a "balloon" cartridge reservoir 29 and an integrated brush/holder 31. Application of pressure on the cartridge will result in teeth-whitening formulation such as varnish to flow to the brush portion.
  • FIGs 4A and 4B show some other possible embodiments of the formulation reservoir.
  • Reservoir 28 has a seal 30 which is positioned between the brush and the reservoir in the cartridge.
  • the seal can be opened in various ways.
  • the seal can be peeled off, as shown in Figures 4 A and 4B. Additional ways of breaking the seal include the application of force when the reservoir is pressurized. By using pressure against the reservoir, a peak force will be presented and the seal will open at that position.
  • Another example uses a "kiss" cutting technology involving a multi-layered seal which is cut partly through. With the application of pressure inside the reservoir, the seal will burst along the partially cut (weak) lines.
  • the reservoir is broken by a needle on the brush which pierces the seal when the brush/cartridge combination is positioned in an applicator device.
  • Figures 5 and 6 show a single-use brush in combination with a multi-treatment (reusable) varnish reservoir.
  • the reservoir is shown at 34 and contains a plurality of individual whitening treatments, e.g. total of 3 ml.
  • a brush 36 is removably positioned on one end 38 of the reservoir.
  • the applicator includes the capability of applying pressure to move the varnish out the end of the reservoir into the brush.
  • the assembly of Figure 5 also includes a cap 40 which maintains the shelf life of the assembly. In use of the applicator, cap 40 is removed and a new brush positioned on the reservoir. After use, the brush becomes hard due to air-drying of the varnish, but acts as an airtight seal for the varnish in the main reservoir. At the next use, the old dried brush is removed and a new one inserted.
  • Figure 6 shows a variation of a portion of the arrangement of Figure 5, which includes a Luer lock-type interface 46 which provides a fluid-tight connection between the reservoir and the brush 48.
  • the brush 48 includes a small tube element 48 which acts as a flow restrictor for accurate dosing. Tube 48 also prevents the reservoir varnish from becoming hardened within the reservoir. The brush itself will become hard due to the drying varnish, but as indicated above is replaceable upon each new use. The reservoir is available for subsequent uses.
  • Figure 7 shows a closing system which includes a brush holder 60, a brush 62, a brush cap 64 and a female Luer lock with flow restrictor 66.
  • a reservoir 68 is included, with a dosing pen assembly 70.
  • a male Luer lock 72 is provided at the forward end of the reservoir, and a cap 74 for covering the forward end of the male Luer lock.
