An eating surface assembly comprising a tray for supporting food items thereon; a socket integrally formed in the tray; a receptacle; and a plug integrally formed on the receptacle. The plug is adapted for mating with the socket in the tray for releasably securing the receptacle on top of the tray.

An eating surface assembly comprising a tray for supporting food items thereon; a socket integrally formed in the tray; a receptacle; and a plug integrally formed on the receptacle. The plug is adapted for mating with the socket in the tray for releasably securing the receptacle on top of the tray. The plug includes a flange which is sized and configured so that its upper surface is substantially flush with the upper surface of the tray when the receptacle is secured to the tray. This creates a substantially continuous, uniform, level surface around the receptacle.

Having thus described the preferred embodiment of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following: 1. An eating surface assembly comprising: a tray for supporting food items thereon, the tray presenting an upper surface; a socket integrally formed in the tray; a receptacle; and a plug integrally formed on the receptacle and adapted for mating with the socket in the tray for releasably securing the receptacle on lop of the tray, the plug including a flange presenting an upper surface, the flange sized and configured so that its upper surface is substantially flush with the upper surface of the tray when the receptacle is secured to the tray, wherein the socket is a bayonet-type socket including a generally vertically-extending cylindrical sidewall depending from the top surface of the tray; a generally horizontally-extending shelf projecting inwardly from a lower edge of the cylindrical sidewall, the shelf defining an aperture extending through the tray; and a pair of spaced, inclined locking ramps depending from a lower face of the shelf. 2. The eating surface assembly as set forth in claim 1 wherein the tray is configured for removably attaching to a highchair. 3. The eating surface assembly as set forth in claim 1, wherein the horizontally-extending shelf includes two arcuate of increased width which define a pair of opposed keyway slots. 4. The eating surface assembly as set forth in claim 3, wherein the plug is a bayonet-type plug including a generally washer-shaped flange extending radially outward from a lower surface of the receptacle; a hollow, generally ring-shaped base depending from a lower surface of the flange; and a pair of locking tabs extending radially outward from a lower surface of the ring-shaped base and dimensioned to be received within the keyway slots of the socket. 5. The eating surface assembly as set forth in claim 4, the plug further including a handle bisecting the hollow ring-shaped base. 6. The eating surface assembly as set forth in claim 4, the flange presenting an outer margin and the locking tabs presenting an outer margin, wherein the outer margin of the locking tabs does not extend beyond the outer margin of the flange. 7. An eating surface assembly comprising: a tray for supporting food items thereon, the tray presenting an upper surface; a socket integrally formed in the tray; a receptacle; and a plug integrally formed on the receptacle and adapted for mating with the socket in the tray for releasably securing the receptacle on top of the tray, the plug including a flange presenting an upper surface, the flange sized and configured so that its upper surface is substantially flush with the tipper surface of the tray when the receptacle is secured to the tray, further including a gasket for positioning between the plug and the socket for substantially sealing gaps between the plug and the socket for inhibiting migration of food or liquids into the socket when the receptacle is secured on top of the tray. 8. The eating surface assembly as set forth in claim 7, wherein the receptacle is selected from the group consisting of a bowl, a plate, a compartmentalized plate, a saucer, and a cup. 9. The eating surface assembly as set forth in claim 7, further including a cover for covering the socket in the tray when the receptacle is removed from the tray, the cover including a generally planar plate dimensioned to substantially close the socket and a plug depending from the plate for mating with the socket in the tray for releasably securing the cover to the tray. 10. The eating surface assembly as set forth in claim 7, wherein the flange includes a pair of depending, generally L-shaped ledges which define a T-shaped slot for receiving and retaining the gasket therein. 11. A high chair comprising: a seat; leg structure for supporting and elevating the seat above a floor; and a tray assembly that can be removably attached adjacent the seat for supporting food or liquid thereon, the tray assembly including a tray presenting an upper surface; a socket integrally formed in the tray; a receptacle; and a plug integrally formed on the receptacle and adapted for mating with the socket in the tray for releasably securing the receptacle on top of the tray, the plug including a flange presenting an upper surface, the flange sized and conligured so that its upper surface is substantially flush with the upper surface of the tray when the receptacle is secured to the tray, wherein the socket is a bayonet-type socket including a generally vertically-extending cylindrical sidewall depending from the top surface of the tray; a generally horizontallyextending shelf projecting inwardly from a lower edge of the cylindrical sidewall, the shelf defining a plug aperture extending through the tray; and a pair of spaced, inclined locking ramps depending from a lower face of the shelf. 12. The eating surface assembly as set forth in claim 11, wherein the tray is configured for removably attaching to a highchair. 13. The eating surface assembly as set forth in claim 11, wherein the horizontally-extending shelf includes two arcuate areas of increased width which define at least one opposed keyway slot. 14. The eating surfrce assembly as set forth in claim 13, wherein the plug is a bayonet-type plug including a generally washer-shaped flange extending radially outward from a lower surface of the receptacle; a hollow, generally ring-shaped base depending from a lower surface of the flange; and at least one locking tab extending radially outward from a lower surface of the ring-shaped base and dimension to be received within the keyway slot. 15. The eating surface assembly as set forth in claim 14, the plug further including a handle bisecting the interior of the hollow ring-shaped base. 16. A high chair comprising: a seat; leg structure for supporting and elevating the seat above a f1oor; and a tray assembly that can be removably attached adjacent the seat for supporting food or liquid thereon, the tray assembly including a tray presenting an upper surface; a socket interally formed in the tray; a receptacle; and a plug integrally formed on the receptacle and adapted for mating with the socket in the tray for releasably securing the receptacle on top of the tray, the plug including a flange presenting an upper surface, the flange sized and configured so that its upper surface is substantially flush with the upper surface of the tray when the receptacle is secured to the tray, further including a gasket for positioning between the socket and the plug for substantially sealing gaps between the plug and the socket for inhibiting the migration of food or liquids into the socket when the receptacle is secured on top of the tray. 17. The eating surface assembly as set forth in claim 16, wherein the receptacle is selected from the group consisting of a bowl, a plate, a compartmentalized plate, a saucer, and a cup. 18. The eating surface assembly as set forth in claim 16, further including a cover for covering the socket in the tray when the receptacle is removed from the tray, the cover including a generally planar plate sized and configured to substantially close the socket and a plug depending from the plate for mating with the socket for releasably securing the cover on top of the tray. 19. The eating surface assembly as set forth in claim 16, wherein the flange includes a pair of depending, generally L-shaped ledges which define a T-shaped slot for receiving the gasket therein.
