SINGLE DOSE TOOTH WHITENER DISPENSER AND APPLICATOR, AND METHOD OF TOOTH WHITENING

摘要

A single dose hygienic tooth whitener dispenser and applicator has a chamber (13) . The housing (11) is a bottle having an upper end with a neck (15) and threads (21) receiving a threaded sleeve (23) . The sleeve includes a recess (27) receiving a sponge applicator (29) having a bottom surface overlying an upwardly facing opening (17) of the chamber in the bottle. This opening is initially covered by a hermetic seal (19) . An over-cap (40) includes a bottom facing opening (41) slidable over the sleeve (23) and covers the applicator. Within the over-cap (40) , a pin (49) extends downwardly. The pin has a pointed end (51) facing downward. When it is desired to use the inventive device to whiten the user's teeth, the over-cap (40) is pushed down until the pointed end (51) of the pin (49) extends through the applicator (29) and pierces the seal (19) in the opening (17) of the bottle (11) , whereupon tooth whitener may be dispensed and applied.
