Abstract

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

Claims19

Dependent claims

A dispenser and applicator for liquid, comprising:

a) a container having an internal chamber and an opening initially sealed by a seal such that liquid within said chamber is hermetically sealed therein;
b) a porous applicator mounted on said container above said opening and overlying said seal;
c) an over-cap covering said applicator and opening, said over-cap being movable with respect to said container and carrying a piercing member;
d) said over-cap being movable from a position at which said piercing member is spaced from said seal to a position at which said piercing member extends through said applicator and pierces said seal,
wherein the porous applicator comprises an opening sized to receive the piercing member, the piercing member is disposed in the opening when the piercing member is spaced from the seal, and the porous applicator is formed of a material having a sufficiently high density that the opening narrows when the piercing member is removed from the opening, to preclude free flow of liquid through the opening.
