VIAL FOR DELIVERING CONTENTS ONTO A SUBSTRATE
First Claim
1. A dispenser for dispensing a substance, comprising:
- a vial comprising a substantially circular base having a cavity therein containing the substance and a projecting portion extending outward from said base and defining a conduit communicating with said cavity;
an applicator tip arranged partly alongside said conduit and including at least one internal passage communicating with said cavity, said applicator tip including an applicator portion situated forward of said conduit, said applicator portion including a plurality of spaced-apart projections at a distal application surface; and
a cap including an opening, a cavity communicating with said opening and a sealing stopper extending into said cavity toward said opening, said cap being removably attachable to said vial and when attached to said vial, said cavity of said cap accommodating said applicator portion of said applicator tip and said sealing stopper extending into said at least one internal passage so that said cap seals said at least one internal passage of said applicator tip,whereby when said cap is removed from said vial and said base is squeezed, the substance in said cavity is urged out of said cavity through said at least one internal passage of said applicator tip and onto said projections.

Abstract
Dispenser that dispenses a substance onto a substrate, such as a tooth treatment compound onto teeth, includes a vial including a cavity containing the substance and a projecting portion extending outward from the base. An applicator tip is engaged with the conduit and includes an internal passage communicating with the cavity, and an applicator portion situated forward of the conduit and that includes a plurality of spaced-apart projections at a distal application surface, preferably crenellated fingers. A cap is removably attachable to the vial and when attached, the applicator portion of the applicator tip is accommodated in a cavity of the cap and a sealing stopper extends into the internal passage to thereby seal it. When the cap is removed from the vial and the base is squeezed, the substance is urged out of the cavity through the passage of the applicator tip and onto the projections.

10. A dispenser for dispensing a substance, comprising:
-
a vial defining a cavity in which the substance is arranged, said vial including a base and a projecting portion extending outward from said base, said projecting portion including a conduit communicating with said cavity; an applicator tip arranged partly in said conduit and including at least one internal passage communicating with said cavity, said applicator tip including an applicator portion made of an elastomeric material and situated exterior of said conduit, said applicator portion including a plurality of spaced-apart projections at a distal application surface; and a cap including an opening and a cavity communicating with said opening, said cap being removably attachable to said vial and when attached to said vial, said cavity of said cap accommodating said applicator portion of said applicator tip so that said cap seals said at least one internal passage of said applicator tip, whereby when said cap is removed from said vial and said base is squeezed, the substance in said cavity is urged out of said cavity through said at least one internal passage of said applicator tip and onto said projections. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method for manufacturing a dispenser for dispensing a substance, the method comprising:
-
forming, by blow-molding, a vial comprising a substantially circular base having a cavity therein and a projecting portion extending outward from the base and defining a conduit communicating with the cavity; forming from an elastomeric material, an applicator tip including an engagement portion and applicator portion, the engagement portion defining at least one internal passage, the applicator portion defining at least one internal passage and including a plurality of spaced-apart projections at a distal application surface; inserting the engagement portion of the applicator tip into the conduit of the projecting portion of the vial; dimensioning the engagement portion of the applicator tip and the conduit of the projecting portion of the vial to provide a friction fit when the engagement portion of the applicator tip is inserted into the conduit of the projecting portion of the vial; forming a cap including an opening, a cavity communicating with the opening and a sealing stopper extending into the cavity toward the opening; inserting the substance into the cavity in the base; and removably attaching the cap to the vial such that the cavity in the cap accommodates at least the applicator portion of the applicator tip and the sealing stopper extends into the at least one internal passage of the applicator portion so that the cap seals the at least one internal passage of the applicator portion. - View Dependent Claims (19, 20)
