US Patent 12080578 Front opening unified pod

A front opening unified pod includes a container body, a removable front door, and an air curtain apparatus. The container body has bottom and top walls, two side walls, a rear wall connected to the bottom, top, and side walls to define a receiving space, and an opening opposite to the rear wall. The front door closes the opening. The air curtain apparatus includes an air outflow module and an air inflow pipeline connected to the air outflow module. The air outflow module is disposed on one of the top and side walls, is adjacent to the opening, and is located within the receiving space so as to form a laminar air curtain adjacent to the opening for shielding the receiving space.
