While the container has been shown as constructed from sheet material, it is possible to create a similar functioning container by utilizing a frame work for the separate elements and then to cover said frames with a fabric or other soft material.

What I claim is:

1. In a collapsible container, a rectangular bottom; a top rim; and members pivotally interconnecting said bottom and the top rim; side members hingedly mounted on said top rim and movable to engage said bottom when the container is distended; a stirrup rigidly carried by each of said side members, extending outwardly from the edge thereof to the opposite side of the top rim thereof a sufficient distance to constitute a lever; and a flexible handle joining the outwardly extended portions of said stirrups and extending across the top of said container, said handle being drawn to its fullest length when the sides are swung inwardly to collapse the container.

2. In a collapsible container, a rectangular bottom; a top rim; and members pivotally interconnecting said bottom and top rim; inturned flanges along each of two opposite edges of the bottom to form recesses; a pair of side members each hingedly mounted on said top rim and each having an out-turned flange at its bottom edge for engaging respectively one of the bottom recesses when the container is distended; a stirrup integral with each of said side members rigidly extending outwardly from the edge thereof to the opposite side of the top rim therefrom a suflicient distance to constitute a lever; and a flexible handle joining the outwardly extended portions of said stirrups.

3. In a collapsible container, a rectangular bottom; a top rim, and members pivotally interconnecting said bottom and top rim; inturned flanges along each of two opposite edges of the bottom to form recesses; a pair of side members each hingedly mounted on said top rim and each having an out-turned flange at its bottom edge for engaging respectively one of the bottom recesses when the container is distended; a stirrup integral with each of said side members rigidly extending outwardly from the edge thereof to the opposite side of the top rim therefrom a suflicient distance to constitute a lever; and a flexible handle joining the outwardly extended portions of said stirrups whereby to force said side flanges into said recesses when the con tainer is supported thereby.

4. In a collapsible container, a rectangular bottom; a top rim; members pivotally interconnecting said bottom and top rim; side members hingedly mounted on said top rim and positioned to oscillate between said end members; an outturned flange at the bottom of each side member; an inturned flange along each of two opposite edges of said bottom to form recesses for receiving the flanges of the respective side members; abutments formed on said bottom adjacent the ends of the out-turned flanges of the side members to preclude longitudinal movement of said flanges in said recesses; and a flexible hanolle joining said side members at points a sufficient distance from the hinge connection, on the opposite side of the members from said flanges to cause the flanges to move into the respective recesses when the container is supported by the handle.

5. In a collapsible container, a rectangular bottom; a top rim, and members pivot-ally inter connecting said bottom and top rim; inturned flanges along each of two opposite edges of said bottom to form recesses; side members hingedly mounted on said top rim, each having an outturned flange at its bottom edge for engaging one of the recesses when the container is distended; detents preventing accidental removal of the flanges from said recesses; a stirrup rigid with each of said side members extending outwardly from the edge thereof to the opposite side of the top rim therefrom a sufficient distance to constitute a lever; and a flexible handle connecting said stirrups.
