Abstract: A food container includes a box, a cover and a pair of locking wings. The box includes a main body and elastic engaging plates. The main body has a receiving space. The elastic engaging plates are arranged on opposite sides of the receiving space. Each elastic engaging plate includes an elastic arm and a clip. The cover includes a cover plate and engaging slots. The cover is positioned on the main body through the clip inserted in the engaging slot. The locking wings are pivotally coupled to the cover. Each locking wing rotates toward the box to press elastic arms. The elastic arms drive the clips to be disengaged from the engaging slots. Thus, the cover is separated from the box.

Abstract: An air sealing body capable of intensifying air-tightness comprises two outer membranes and two inner membranes. At least a heat resistant section is formed between the inner membranes by means of coated heat resistant material. Four sides of the two outer membranes are thermally sealed and an air filling passage, an air inlet and an air column are thermally formed to across the heat resistant section. The heat resistant section is further thermally sealed with the thermal seal spots. Hence, a structure with the air inlet being forcedly opened during air being filled is constituted and a curved surface zone is formed at the air column near the air filling side. Multiple wrinkles are produced between the inner membranes. A column zone is disposed at a side of the curved surface zone. At least a ring-shaped thermal seal line is attached to at least the inner membranes and disposed next to the column surface zone and outside the curved surface zone.

Abstract: A power supplying system includes a switching control circuit connected to a stand-by power source so as to receive electrical power therefrom. The switching control circuit is further connected to a power-supplying unit and is activated to control operation of the power-supplying unit in a selected one of an ON state, where the power-supplying unit supplies electrical power for operating a heat-dissipating fan, and an OFF state, where the power-supplying unit ceases to supply the electrical power to the heat-dissipating fan.
