Abstract: A friction lock adaptable spacer configured to provide suitable separation between two or more objects. The spacer may be used during the storage, transport, display, and/or use of the objects to separate them and protect them from their surrounding environment. In some embodiments, the spacer is designed to maintain a suitable separation between two or more beverage containers. The spacer has a single piece construction, which reduces assembly and disassembly labor, and also reduces materials required for construction and disposal. The spacer may be constructed from a single piece of material, such as corrugated cardboard.

Abstract: A beverage container closure or lid that is adapted for closing an open end of a beverage container. The lid is selectively couplable to the beverage container and includes a selectively openable stopper that when closed, creates a fluid-tight seal between the beverage container and the environment. The stopper may be selectively opened by a user by the user pressing a button disposed on a side of the beverage container closure. The stopper is subsequently automatically closed when the user releases the button. Thus, a user may open and close the beverage container closure using a single hand without the need to remove the beverage container closure from the beverage container.
