Abstract
An applicator having an applicator end portion and a material end portion. The material end portion forms a container holding a material to be applied with the applicator end portion. Upon separating the material end portion from the handle portion of the applicator, a container is formed which is used to dip the applicator end portion of the applicator into. The present invention is particularly applicable to the dispensing of medicaments, and in particular, dental materials. A single dose of material is integrally formed within the applicator and sealed until ready for use.
Claims19
An applicator device containing a material for dispensing comprising:
- an elongated handle having an applicator end and a material end;
- an applicator formed on said applicator end;
- a neck placed between said elongated handle and said applicator end, whereby said applicator is capable of being angularly disposed relative to said handle;
- a material chamber formed in the material end of said elongated handle and containing the material, said material chamber being initially sealed between said elongated handle and the material end;
- and
- a frangible portion integrally formed within a wall of said elongated handle and placed between said elongated handle and said material end,
- whereby upon separating said material end from said elongated handle an opening is formed in said material chamber permitting said applicator to be placed within said material chamber and the material to be applied with said applicator.
An applicator device containing a material comprising:
- an applicator handle portion;
- an applicator attached to said applicator handle portion;
- a material handle portion initially attached to said applicator handle portion;
- a first frangible portion placed between said applicator handle portion and said material handle portion, whereby said applicator handle portion is capable of being separated from said material handle portion;
- a material portion initially attached to said material handle portion, said material portion having a material chamber containing the material;
- and
- a second frangible portion placed between said material handle portion and said material portion, whereby said material handle portion is capable of being separated from said material portion exposing the material permitting the applicator to be used to apply the material.
A method of applying a material comprising the steps of:
- forming an applicator handle having an applicator end and a material end so that the applicator handle is between the applicator end and the material end;
- sealing the material in the material end of the applicator handle;
- forming a frangible portion between the applicator handle and said material end;
- separating the material end from the applicator handle along the frangible portion forming an opening in the material end exposing the material;
- and
- inserting the applicator end into said material end,
- whereby a predetermined dose of material is capable of being applied.
An applicator device containing a material comprising:
- a handle portion having an applicator end and a material end, the applicator end and the material end being separated by said handle portion;
- an applicator attached to said handle portion on the applicator end, said applicator comprising a loop applicator;
- and
- an initially sealed material portion frangibly attached to said handle portion on the material end,
- whereby when said material portion is separated from said handle portion the material is exposed.
An applicator device containing a material comprising:
- an elongated handle having an applicator end and a material end, said elongated handle positioned between the applicator end and the material end;
- an applicator formed on said applicator end, said applicator comprising a loop applicator;
- a material container attached to said material end, said material container having an initially sealed chamber holding the material;
- and
- a frangible portion integrally formed within said elongated handle separating said elongated handle and said material container,
- whereby upon separating said material container from said elongated handle an opening is toned in said material container permitting application of the material with said applicator.
