Patent attributes
A weight system for supporting a free-standing object comprising a container defining an interior chamber, the container comprising at least one side wall, a lower wall, and an upper wall, where the upper wall is configured to define a fill opening and a closure system comprising first and second closure portions. The first closure portion is arranged to define a first side of the fill opening. The second closure portion is arranged to define a second side of the fill opening. The closure system is arranged to allow the container to be configured in a closed configuration in which the first closure portion engages the second closure portion substantially to prevent access to the interior chamber through the fill opening and an open configuration in which the first closure portion is disengaged from the second closure portion to allow access to the interior chamber through the fill opening.
