A plastic bag stand 10 is formed of wire to include a base 11 and generally U-shaped sides 12 and 13 pivotally mounted on the base to fold flat under the base for packaging and to open upright above the base for supporting the bag. The stand 10 has several improvements involving the way the base 11 is formed and the sides 12 and 13 are pivotally mounted on the base. The base is formed of opposed longitudinals 16 and 17 having central spans spaced apart by less than the width of the sides and a pair of opposed laterals 18 and 19 having mid-regions in the plane of the central spans of the longitudinals. End portions of the longitudinals are bent outward and downward to join the laterals, and S-curves 24 in the laterals make end regions 23 parallel with an offset from the mid-regions. Bonds 20 join the end regions of the laterals with the end portions of the longitudinals, and the sides are pivotally mounted on the end regions of the laterals between and adjacent the S-curves and the bonds. This allows the upper regions of the sides to detent against inside surfaces of the S-curves when folded and lower regions of the sides to detent against outside surfaces of the S-curves when opened upright.

A plastic bag stand formed of wire to include a base and generally U-shaped sides pivotally mounted on said base to fold flat under said base for packaging and to open upright above said base for supporting a plastic bag, said stand comprising: a. a pair of opposed longitudinal wires having central spans spaced apart by less than the width of said sides; b. a pair of oposed lateral wires having mid-regions arranged approximately in the plane of said central spans of said longitudinal wires; c. end portions of said longitudinal wires being bent outward and downward to join said lateral wires; d. end regions of said lateral wires being parallel with and offset from said mid-regions; e. S-curves in said lateral wires between said mid-regions and said end regions; f. bonds joining said end regions of said lateral wires and said end portions of said longitudinal wires at the lower ends of said downward bends in said longitudinal wires; and g. said sides being pivotally mounted on said end regions of said lateral wires between and adjacent said S-curves and said bonds so that upper regions of said sides detent against inside surfaces of said S-curves when folded and lower regions of said sides detent against outside surfaces of said S-curves when opened upright.
