A self-anchoring, low profile container anchor with directional release and attachment capability comprises a lower base member, an upper movable member adapted for attachment to a container, and a seal member on the base member. The seal member is configured to engage an external reference surface and form a substantially airtight seal therewith that defines a periphery of a controlled pressure zone. A sealing valve disposed on a valve seat is operably connected to the movable member for lifting off the valve seat and vent the controlled pressure zone when the movable member is raised a first predetermined distance. However, the movable member can tilt a second predetermined tilting distance without the sealing valve lifting off the valve seat, thus providing tilt resistance.

The apparatus of claim 1, wherein said sealing valve is operably connected to said movable member by a pin that extends through a pin-receiving opening in said movable member, said pin having a head flange that engages said movable member when said movable member has been lifted said first predetermined distance. 3. The apparatus of claim 2, wherein said pin is vertically adjustable on said sealing valve so that said first predetermined distance can be adjusted. 4. The apparatus of claim 2, wherein said movable member is operably connected to said base member by a set of movable member peripheral tabs that engage a corresponding set of peripheral stops on said base member peripheral sidewall when said movable member has been lifted said second predetermined distance. 5. The apparatus of claim 4, wherein said movable member is sized so that a distance between diametrically opposing pairs of said peripheral tabs is such that tilting said movable member said second predetermined distance will not result in said movable member being raised said first predetermined distance and engaging said head flange. 6. The apparatus of claim 5, wherein there is a single pin operably connecting said valve to said movable member, and wherein said pin-receiving opening is situated equidistantly from said movable member peripheral tabs. 7. The apparatus of claim 1, wherein said movable member is nested entirely within an area defined by said base member peripheral sidewall. 8. The apparatus of claim 1, wherein said seal member is nested entirely within said area defined by said base member peripheral sidewall. 9. The apparatus of claim 1, wherein said container support assembly comprises a generally disk-shaped puck assembly. 10. The apparatus of claim 1, wherein said base member peripheral sidewall is generally ring-shaped, and wherein said base member interior structure is generally annular-shaped with a central aperture that is generally circular in shape. 11. The apparatus of claim 10, wherein said seal member is formed with a central aperture and is generally annular in shape, said seal member being attached to said lower side of said base member interior structure. 12. The apparatus of claim 11, wherein said lower side of said base member interior structure is tapered such that said seal member forms a frustoconical shape. 13. The apparatus of claim 1, wherein said seal member is attached to said lower side of said base member interior structure by way of a seal retainer that inserts through said central aperture in said seal member and engages said central aperture in said base member interior structure. 14. The apparatus of claim 13, wherein said seal retainer includes a central well whose bottom defines said valve seat, and one or more apertures providing an air pathway from said valve seat to a lower side of said seal retainer that is in fluid communication with said seal lower side. 15. The apparatus of claim 14, wherein said valve seat comprises a resilient member mounted on said bottom of said seal retainer central well. 16. The apparatus of claim 15, wherein said sealing valve comprises a generally circular disk member and said resilient seal comprises an O-ring. 17. The apparatus of claim 16, wherein said sealing valve includes peripheral tabs that reduce friction between said sealing valve and a side portion of said seal retainer central well. 18. The apparatus of claim 1, wherein said base member interior structure is a load-bearing structure and said movable member is supported thereon. 19. The apparatus of claim 1, in combination with a container mounted on said movable member to form a container assembly. 20. 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 a container, and a lower side 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; andsaid movable member and said seal member being nested entirely within an area defined by a periphery of said base member;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;wherein said sealing valve is operably connected to said movable member by a pin that extends through a pin-receiving opening in said movable member, said pin having a head flange that engages said movable member when said movable member has been lifted said first predetermined distance. 21.
