Claim:
A self-anchoring, low profile container anchor with directional release and attachment capability, comprising: a container support assembly including a lower base member and an upper movable member; said base member having a peripheral sidewall and an interior structure; said movable member being disposed on an upper side of said base member interior structure; said movable member having an upper side configured for attachment to a container, a lower side, and being configured to operably connect to said base member; a seal member disposed on a lower side of said base member interior structure; said seal member having a lower side configured to engage an external reference surface and form a substantially airtight seal therewith that defines a periphery of a controlled pressure zone between said seal member and said reference surface; a valve seat in said container support assembly, said valve seat being in fluid communication with said seal member lower side; a sealing valve disposed on said valve seat, said sealing valve being operably connected to said movable member for lifting off said valve seat when said movable member is raised; said sealing valve and said movable member being operably interconnected in a manner that requires said movable member to lift past a first predetermined distance before said sealing valve begins to lift off said valve seat; said base member and said movable member being operably interconnected in a manner that allows said movable member to tilt a second predetermined tilting distance without said sealing valve lifting off said valve seat, and to prevent said movable member from tilting beyond said predetermined tilting distance; whereby when said sealing valve is lifted from said valve seat due to said movable member being raised past said first predetermined distance, said controlled pressure zone is vented to atmospheric pressure; and whereby said controlled pressure zone is maintained when said movable member is tilted said second predetermined distance.
