Portable toilet
（重定向自Portapotty）
A portable toilet, often referred to as a porta-potty, honey bucket (American English), Port-a-John (American English), or Portaloo (UK), ("Portaloo" is a UK and European Community registered trade mark) is a simple portable enclosure containing a chemical toilet (a toilet bowl filled with disinfectant instead of water), and is typically used as a temporary toilet for construction sites or large gatherings because of its durability and convenience. Most portable toilets have black open-front U-shaped toilet seats with a cover. They are often constructed out of lightweight molded plastic.
