Self-funneling flexible container

A self-funneling flexible material container system at a hydrocarbon well services or operation site, comprising:

• a self-funneling flexible container, wherein the self-funneling flexible container comprises one or more bands disposed on a bottom of the self-funneling flexible container, and wherein each of the one or more bands has an elasticity;
• a frame coupled to the self-funneling flexible container;
• wherein the self-funneling flexible container transitions to an expanded position when a material is flowed into the self-funneling flexible container, and wherein the self-funneling flexible container transitions to a contracted position when the material is discharged from the self-funneling flexible container;
• wherein the one or more bands form at least one pattern selected from the group consisting of an L-shaped pattern, an inverted L-shaped pattern, and a curved pattern;
• and
• wherein the bottom forms a chute when transitioned to the contracted position.
