  • Patent number: 5071002
    Abstract: A multi-sided, invertible holder for beverage containers or the like comprises a hollow receptacle with a plurality of pairs of flat sides. A preferred embodiment is a hollow cube configuration having six flat sides. Four sides have holes through side walls; one side has a slot extending the length of the side wall; and another side has a hole through the side wall and a slot extending radially outward from the hole, and another side has a solid side wall. In use, the holder sits on a generally level surface and may be inverted such that any one of the side walls is on the top side to slidably receive a beverage container or other open top receptacle while the opposed bottom flat surface provides a stable supporting base. The invertible holder provides sufficient stability to prevent tipping or spilling the contents of the container.
