A tray for dispensing a material to be applied with an applicator having a plurality of applicator support openings. The applicator support openings have a depth and width sufficient so that when an applicator is placed therein, it is held substantially upright. The material and applicator support wells may be funnel shaped. The relatively deep narrow funnel shape protects the material placed therein from ambient light, contamination, evaporation, and spilling. The invention is particularly well suited to use in a dental procedure that may require the application of multiple different materials or materials that react with one another or that are light activated. The plurality of different material wells are readily identifiable and keep the different materials separate and ready for use.

What is claimed is: 1. A dental material holding and dispensing device comprising: a tray for containing a readily flowable dental material used by dentists for effecting various tooth restoration procedures, and an associated dental applicator for use therewith, said tray including a top planar surface, a depending side wall circumscribing said top planar surface forming a base, at least one material well formed in said top planar surface, said at least one material well having a frustroconical inlet portion defining an opening in said top planar surface, said inlet portion converging inwardly from said top planar surface, and a generally cylindrical portion having a closed bottom wall connected to said inlet portion whereby the depth and lateral width of said cylindrical portion are such that the surface tension of a readily flowable dental material contained in said cylindrical portion prohibits the readily flowable dental material from spilling out of said at least one material well if inverted, and said dental applicator having an elongated handle and an applicator end portion connected to one end of said elongated handle, said applicator end portion being sized so as to be received in said cylindrical portion of said at least one material well, said dental applicator being supportable within said cylindrical portion in a generally upright position to facilitate the grasping thereof by a user, and said cylindrical portion having a width not greater than three times the width of said applicator end portion. 2. A dental material holding and dispensing device comprising: a tray for containing a readily flowable dental material used by dentists for effecting various tooth restoration procedures, and an associated dental applicator for use therewith, said tray including a top planar surface, said top planar surface including an uppermost planar portion and a lower planar portion, a depending side wall circumscribing said top planar surface forming a base, a plurality of material wells formed in said uppermost planar portion, each of said material wells having a frustroconical inlet portion defining an opening in said uppermost planar portion, said inlet portion converging inwardly from said uppermost planar portion, and a generally elongated cylindrical portion having a closed bottom wall connected to said inlet portion whereby the depth and lateral width of each of said material wells are such that the surface tension of a readily flowable dental material contained in each of said material wells prohibits the readily flowable dental material from spilling out of said material wells if inverted, and said dental applicator having an elongated handle and an applicator end portion connected to one end of said elongated handle, said applicator end portion being sized so as to be received in said cylindrical portion of each said material well, said dental applicator being supportable within said cylindrical portion in a generally upright position to facilitate the grasping thereof by a user, and said lower planar portion allowing for facilitating grasping of said tray by the user. 3. A dental material holding and dispensing device as defined in claim 2 wherein said cylindrical portion of each of said material wells defines a reservoir for the readily flowable dental material wherein the width of said cylindrical portion is substantially less than the axial length of said cylindrical portion. 4. A dental material holding and dispensing device as defined in claim 3 wherein the width of said cylindrical portion is not greater than three times the width of said applicator. 5. A readily disposable dental material and holding device comprising: a tray for containing a readily flowable dental material selected from the group consisting of dental bonding agents, dental adhesives, dental etchings, acids, dental desensitizers, and dental solvents, an associated dental applicator for use therewith, said tray including a circular top planar surface, said circular top planar surface including an upper planar portion and a lower planar portion, said upper planar portion defining an arcuate portion of said circular top planar surface, a depending side wall circumscribing the periphery of said circular top planar surface, a plurality of circumferentially spaced apart material wells formed in said upper planar portion, each of said material wells including a frustroconical inlet portion defining an opening in said upper planar portion, said inlet portion converging inwardly from said upper planar portion, and a generally cylindrical portion terminating in a closed bottom wall connected to said inlet portion whereby the depth and lateral width of each said material well are such that the surface tension of a readily flowable dental material contained in each said material well prohibits the readily flowable dental material from spilling out of said material well if inverted, said associated dental applicator including an elongated handle and an applicator end portion connected to one end of said handle, said applicator end portion being sized so as to be received in said cylindrical portion, said dental applicator being supportable within said cylindrical portion in a generally upright position to facilitate the grasping thereof by a user, said cylindrical portion having a width not greater than three times the width of said applicator end portion, each said material well having a depth sufficient to minimize the exposure of the flowable dental material therein to ambient light, evaporation and, contamination. 6. A readily disposable dental material and holding device as defined in claim 5 wherein said tray is formed of an opaque, thin, plastic sheet.
