The present invention relates to a tooth whitener applicator and method. In the prior art, it is known to whiten teeth using various well known tooth whitening compositions. However, the tooth whitening process is often cumbersome and messy. Most dentists offer services involving tooth whitening, however, for the average patient, it is expensive to have the dentist perform the whitening services. As such, a need has developed for a tooth whitening applicator that is both inexpensive and easy to use.
Applicant is aware of U.S. Pat. No. 5,098,297 to Chari et al. which discloses an apparatus for application of a tooth desensitizing composition. Chari et al. fail to teach or suggest tooth whitening and disclose the use of a swab-type applicator that retains and dispenses a tooth desensitizer onto the teeth. Chari et al. disclose a separate filter disc designed to prevent shards of glass from an ampule containing the desensitizing solution from escaping into the mouth of the patient. The present invention differs from the teachings of Chari et al. in several respects. First, the present invention contemplates application of a tooth whitening composition rather than a tooth desensitizing composition. Second, the present invention contemplates evacuating the interior of the glass ampule containing a monodose of the tooth whitening composition so that its shelf life is extended. Third, the present invention contemplates use of a brush to dispense the tooth whitening composition with the brush doubling as the filter preventing glass shards from entering the mouth of the patient. The tooth whitening composition is somewhat more viscous than the tooth desensitizing composition taught by Chari et al. Due to its increased viscosity, the wad-type applicator of Chari et al. would not be suitable for use in dispensing the tooth whitening composition of the present invention.
The present invention relates to a tooth whitener applicator and method. The present invention includes the following interrelated objects, aspects and features:
(1) In a first aspect, the present invention contemplates an apparatus for practicing the method thereof. The apparatus includes a glass ampule having a monodose of a tooth whitening solution vacuum sealed therein. The ampule is contained within a cylindrical plastic sleeve closed at one end and enclosed at its other open end by the proximal termination of a brush-type applicator. An adhesive such as glue is used to adhere the periphery of the brush to the inner surfaces of the open end of the plastic sleeve.
(2) The bristles preferably have circular cross-sections so that when they are tightly packed together and peripheral bristles are adhered to the plastic cylinder, interstices between adjacent bristles are sufficiently large enough to permit flow through of the tooth whitening composition while being sufficiently small enough to prevent shards of glass from the ampule, when broken open, to pass therethrough.
(3) A cardboard sleeve surrounds the plastic cylinder to protect the user from the glass ampule when broken.
(4) The bristles of the brush applicator are sized and configured to permit brushing between teeth into the tooth enamel. It is in these areas where stains often accrue, namely, the inter-proximal areas of the teeth. Thus, a brush rather than a wad is chosen due to its effectiveness with regard to the anatomy of the teeth that are being treated.
(5) The method of using the inventive apparatus is as follows:
As such, it is a first object of the present invention to provide a tooth whitener applicator and method of applying tooth whitener.
It is a further object of the present invention to provide such an invention in which tooth whitening composition is vacuum sealed within a glass ampule.
It is a yet further object of the present invention to provide such an apparatus in which a brush with tightly packed bristles is used to dispense the tooth whitening composition onto the teeth.
It is a still further object of the present invention to provide such an apparatus wherein a cardboard sleeve is placed over a plastic cylinder enclosing the glass ampule.
It is a still further object of the present invention to provide a method of using the apparatus to whiten the user's teeth.
These and other objects, aspects and features of the present invention will be better understood from the following detailed description of the preferred embodiments when read in conjunction with the appended drawing figures.

As such, an invention has been disclosed in terms of a preferred embodiment of the apparatus and a preferred sequence of steps in practicing the method of use thereof of great novelty and utility.
Of course, various changes, modifications and alterations in the teachings of the present invention may be contemplated by those skilled in the art without departing from the intended spirit and scope thereof.
As such, it is intended that the present invention only be limited by the terms of the appended claims.
