Besides having a lid, what feature was required for the refuse container mandated by the 1883 Paris Ordinance?

a tight-fitting bottom

The 1883 Paris ordinance, championed under the influence of Eugène Poubelle, established stringent criteria for household refuse receptacles designed to improve sanitation and facilitate organized municipal collection. In addition to mandating a lid to cover the contents, the regulation explicitly required that the container possess a tight-fitting bottom. This specification was essential for preventing leakage of waste fluids onto the streets or into public areas, which was a major contributing factor to poor hygiene and pest proliferation in dense urban environments. The combination of the lid and a sealed bottom ensured the refuse remained relatively contained until collection.
