ABSTRACT:
A double-seal mechanism is provided on a cover member for sealing closed a container main body. The double-seal mechanism includes an inner seal piece that seals an interior of the container main body and is positioned between an inner seal reception section of a flange of the container main body and a seal pressing section of the cover. An outer seal piece forms a second seal between the container main body and the periphery of the cover member. The inner seal piece has a rounded distal end fitted into a fitting groove in the flange. A cover member fixing unit of the cover member includes a latch shaft that is linearly projected from and retracted, a latch roller attached to a tip end of the latch shaft, and a crank mechanism that linearly projects and retracts the latch shaft as the crank mechanism rotates. The latch roller travels along an inclined retracting surface on the container main body which forces the cover member inward into sealing engagement with the container main body.
