A self-combining receptacle for producing a coated or partially-coated product or an admixture product is provided according to the invention. This receptacle can comprise a food service container for finger food like French fries having a sealed package of ketchup or other condiment installed in the bottom of the container and below the French fries where a closure panel extending outside the receptacle is pulled in a lateral direction away from the receptacle to peel off the closure panel to open the condiment package inside the container whereupon the French fries automatically drop down inside the container into the condiment contained in the now-opened condiment package. Alternatively, the self-combining receptacle may comprise two open faced vessels that are fitted together to join their common open faces with a common closure panel sealing the two open faces to divide the two vessels containing separate components of an admixture product. When the closure panel is removed from the receptacle or pierced by means of an integral utensil device, the two product components can be mixed together to produce the admixture product. Such an admixture product may comprise a food dish like fruit, granola pieces, chocolate pieces, or syrup mixed into yogurt or ice cream, or an industrial product like two resin components mixed together to produce an epoxy adhesive.
