14. The apparatus of claim 13 , wherein the respective pivot axes of the first and second hinges are substantially horizontally oriented and substantially parallel to one another, and wherein each of the first and second hinges is spring-loaded to respectively bias the first and second grippers to the respective first positions.
15. The apparatus of claim 14 , wherein the container engaging portion of each of the first and second grippers includes a wire frame including four contact points arranged in a substantially rectangular arrangement, wherein the wire frame of the container engaging portion of each of the first and second grippers includes first and second generally vertical members, wherein first and second contact points among the four contact points for the wire frame of the container engaging portion of each of the first and second grippers are defined on the first generally vertical member, and wherein third and fourth contact points among the four contact points are defined on the second generally vertical member.
16. The apparatus of claim 15 , wherein each of the first and second grippers further includes a wing portion adjacent the lateral opening, the respective wing portions of the first and second grippers configured to urge the first and second grippers toward the respective second positions when the beverage container is pushed into the lateral opening and against the respective wing portions.
17. The apparatus of claim 16 , wherein the wing portion of each of the first and second grippers is a first wing portion and is oriented on a first side of the lateral opening, and wherein each of the first and second grippers further includes a second wing portion disposed on a second, opposite side of the lateral opening from the respective first wing portion such that the beverage container may be passed through either of the first and second sides of the lateral opening during insertion into and/or removal from the holder.
18. The apparatus of claim 1 , wherein the base includes a substantially vertical portion that projects upwardly towards the beverage container when the beverage container is held by the holder in the inverted orientation and a substantially horizontal portion, wherein the substantially vertical portion defines a first annular support configured to support a shoulder of the beverage container when the beverage container is a narrow mouth beverage container and the substantially horizontal portion defines a second annular support configured to support a lip of the beverage container when the beverage container is a wide mouth beverage container, and wherein the substantially vertical portion extends externally to the beverage container when the beverage container is the narrow mouth beverage container and extends internally to the beverage container when the beverage container is the wide mouth beverage container.
