Abstract:
A disposable standing trash bag comprising a flexible container having an open top, a closed bottom and an encircling sidewall in combination with a foldable frame inside the container, said frame comprising:at least three vertically stacked horizontal hoops, each of said hoops having a diameter substantially equal to the internal diameter of the encircling sidewall;a first plurality of spaced apart vertical supports, each vertical support having a rib with a first end portion journaled on an upper of the horizontal hoops and a second end portion that is free, and a strut having a first end portion journaled on a middle of the horizontal hoops and a second end portion pivotally connected to said rib at a third pivot spaced substantially inwardly from said second end portion of the rib, a second plurality of spaced apart vertical supports, each vertical support having a rib with a first end portion journaled on the middle of the horizontal hoops and a second end portion that is free, and a strut having a first end portion journaled on a lower of the horizontal hoops and a second portion pivotally connected to said rib at a third pivot spaced substantially inwardly from said second end portion of the rib; and,a slider on the rib slidable over the second pivot under force of gravity when the rib is in vertical alignment with the strut and a stop on one of said rib and said strut preventing said slider from sliding past said second end portion of the rib,whereby said slider restrains the strut and rib from pivoting at the third pivot when said rib is in vertical alignment with the strut but releases the strut and rib when the metal frame is turned upside down and the slider slides back over the third pivot, releasing the second end portion of the rib so that the strut and rib can pivot at the third pivot and allowing the frame to fold with the strut and the rib extending radially inwardly of the hoops.
