A stand for supporting an open-ended conical plastic bag, has an upper rim portion, over which a portion of the bag open end may be folded, in securing relation; a like lower rim portion supports the stand in stable, self-supporting relation. The stand consists of two identical segment portions, which clip together. Each segment has first and second longitudinal ribs joining the opposed rim portions. Almost half the length of each first rib is arcuately recessed to secure a corresponding length of the other first rib, when reversed, in entered relation within the recess. The arcuate recess has protruding ear portions which serve as clips for securing the entered other first rib, which ear portions also engage the sides of protrusions of the other first rib to stabilize it in the recess. Other local first rib protrusions enter into corresponding recesses located in the bottom of the opposed first rib arcuate recess.

1. A portable stand for attachment of a bag in supported relation thereon, said stand having two identical, first and second, half portions assembled together in secured, adjoining relation to form a shaped upper rim and a shaped lower rim, with supporting rib means extending therebetween, said lower rim portion serving to support said stand from a surface in stable, standing relation;each of said first and second half portions including a first rib forming a part of said rib means; wherein said first rib of said first half portion has at least one protrusion projecting radially from the rib located a predetermined distance from a reference datum, and wherein said first rib of said second half portion has at least one radially disposed recess sized to receive and hold said protrusion located said predetermined distance from said datum, said protrusion when received in said recess serving to maintain said first rib of said first half portion in secured, engaged relation with said first rib of said second half portion to retain said portions in their assembled adjoining relation.2. The portable stand as set forth in claim 1, wherein said upper and lower rims subtend a partial are of a circle and are flexible, to enable the size of the arc to be varied.3. The portable stand as set forth in claim 1, wherein said upper and said lower rims are in adjoining relation at the juncture of said first ribs, and wherein the end of said rims remote from said first ribs are in mutually spaced apart relation.4. The portable stand as set forth in claim 1, wherein said first rib has a second protrusion and car portions disposed at similar, spaced apart positions on opposed sides of said reference datum, said second protrusion of one said rib serving to engage car portions of another said first rib, in use to maintain said two first ribs in mutually secured, non-twisting relation.5. The portable stand as set forth in claim 1, wherein said upper and lower rims are of substantially arcuate form subtending less than 180 degrees.6. The portable stand as set forth in claim 1, wherein said first ribs each have a centrally located portion offset in underlying relation below a said rim, said offset portions combining upon assembly to form an aperture.7. The portable stand as set forth in claim 1, in combination with a bag supported from said upper rim portions.8. A two-piece portable stand comprising two identical portions, each having opposed upper and lower rim portions; a first and second rib connecting the rim portions in mutually spaced, substantially parallel relation, said first rib including male and female clip means in mutually spaced relation along its length, whereby, on reversing one said first rib lengthwise, relative to the other said first rib, and bringing said male clip means of said first ribs into registry with said female clip means, said ribs may be clipped together in mutually secured relation to assemble said stand, wherein said rim portions serve to support said stand in a stable, upright position for the positioning of a bag between said portions, in draped supported relation from the upper end of the stand.9. The portable stand as set forth in claim 8, wherein each said first rib includes ear portions in mutually opposed, spaced relation to receive a protruding portion of the other said first rib in entered relation between said ear portions, to substantially preclude twisting of one of said first rib relative to the other said first rib, and to maintain said two first ribs in mutually engaged relation.10. A portable stand for attachment of a bag in supported relation thereon, said stand having two identical, first and second, half portions, said two portions being capable of assembly in secured, adjoining relation to form a shaped upper rim and a shaped lower rim, with supporting rib means extending therebetween, wherein a first rib of said first stand portion is in secured, engaged relation with a first rib of said second stand portion, said first rib of said first portion and said first rib of said second portion together forming a part of said rib means; and said lower rim portion supports said stand in stable, standing relation, and wherein said first ribs each have a centrally located portion offset in underlying relation below a said rim, said offset portions combining upon assembly to form an aperture.
