Description

FIELD OF THE INVENTION
• The present invention is generally related to the field of beverage containers.
BACKGROUND OF THE INVENTION
• Restaurants, cafeterias and coffee shops often serve hot and cold beverages in disposable cups with lids. Conventional designs include a plastic lid and paper cup. Conventional designs for the cup itself generally have a rolled paper opening, forming a lip or bead on the upper edge. In order for cups to be packable in large numbers these types of cups are generally formed in a tapered conical shape with the top opening of the cup of a larger diameter than the bottom diameter of the cup. When filled with a liquid, this shape of the cup raises the center of gravity, making the cup highly unstable.
• Hot beverages pose a potential danger for consumers because they may be at or near scalding temperatures. Many conventional designs have been proposed to mitigate this danger by: insulating the body of the cup from burning the hand of the drinker; increasing the structural strength of the cup to prevent the cup from collapsing; and reducing scalding accidents with more secure lid designs. Beverages are frequently carried on slick plastic trays, making spills a common problem when carrying multiple beverages or beverages and food in typical top heavy disposable cups.
• Tabletop stains from beverage cups are generally prevented with coasters on the tabletop. A few designs have been proposed for combining the functions of a lid and coaster together. These designs share a common problem of being unstable and have not enjoyed adoption by consumers.
SUMMARY OF THE INVENTION
• Disclosed is a design for a combination cup and base structure, including cooperating structural features such that the cup snaps into the base structure.
• Disclosed are embodiments for a combination cup and lid which include features such that the lid may act as a lid, a coaster, and a stable supporting base for the beverage cup in different configurations, including a single or multi-beverage tray, or stacked beverages.
• In a disclosed combination design cup and base, the cup includes an annular bead on a protruding edge of the bottom of the cup. The base design includes an inner annular protrusion sized to guide the annular bead on the bottom of the cup into an annular grove on the top inside surface protrusion. The annular groove is sized to fit the bead firmly, forming a stabilizing structure for the beverage cup.
• In various embodiments, both the top edge or rim of the cup and the bottom edge include an annular bead. In various embodiments, the beaded top and bottom edges are formed by a rolled edge of the cup's paper based material. The base design includes an inner annular protrusion sized to guide the annular bead on the bottom of the cup into an annular grove on the top inside surface protrusion. The annular groove is sized to fit the bead on the cup firmly, forming a stabilizing structure for the beverage cup. In various embodiments which include acting as a lid, the base design includes an outermost annular groove on the bottom surface of the base (lid). The groove is sized to snap tightly over the bead on the annular rim of the cup to form a cup and lid combination in this configuration. Both the cup and base (lid) are stackable when they include these disclosed structures.
