ABSTRACT:
A light-emitting inflatable envelope structure equipped with a nozzle composed of at least two overlapped membranes. The lateral edges of the membranes are fused with or adhered to each other to define an air passage communicating an inner side of the envelope with an outer side. The air passage is formed with at least one receptacle for receiving a light emitting body. After the envelope is inflated through the nozzle, the air pressure in the envelope inwardly compresses the membranes of the air passage to achieve an air-tight state of the air passage. The light emitting body in the receptacle is directly enclosed by the two membranes of the air passage and firmly associated with the envelope without using any other clamping or connecting member.
