DISPENSING VIAL
First Claim
1. An improved dispensing vial, comprising:
- a) a container having an internal chamber containing a liquid to be dispensed therefrom, the liquid having a viscosity within the range of 14000 to 21000 CP, the chamber having a first opening from which the liquid may be dispensed;
b) an applicator tip mounted on said container, said applicator tip including a passage fluidly connected to said first opening and an applicator remote from said container and comprising a plurality of concentric rows of projections surrounding a second opening at an end of said passage, said projections having a degree of stiffness defined by a Shore A hardness in the range of 35-75; and
c) a cap overlying said applicator tip and including a shaft entering said passage to seal said passage and chamber.

Abstract
A dispensing vial includes three component parts, a container for an oral care formulation, an applicator tip, and a cap removably overlying the tip. The cap includes a 4-way locking system. The applicator tip has concentric rows of upwardly extending projections with the outer peripheral row of projections or nibs being longer and higher than the inner peripheral row. The projections facilitate maximum flexibility when used in the oral cavity. Preferably, the applicator projections are made of polyethylene or polypropylene with a Shore A hardness in the range of 35-75. Preferably, the oral care formulation is maintained at a viscosity in the range of 14000-21000 CP. This combination facilitates the formulation easily dispensing from the container, spreading over the applicator projections, and being applied within the oral cavity of the user.
