PROBLEM TO BE SOLVED: To provide a sealed container with a novel pump adapter which excels in productivity and opening work efficiency while securing the sealability of a container body.SOLUTION: The adapter 5 includes a flange part 5a arranged at the upper end of an opening part of the container, and a case part 5b hanging from the flange part 5a through the inside of the opening part and forming a storage space R5 of a pump cylinder on the inside. The lower end of the case part 5b is formed as a lower end cylinder part 5c for fittingly holding the outer peripheral surface of an end cylinder of the pump cylinder. A cap 6 includes a mounting cylinder 6a removably threaded with the opening part of the container body while surrounding the opening part; a fitting shaft part 6c fittingly held to the inner peripheral surface of the case part 5b while hanging from a top wall 6b provided at the upper end of the mounting cylinder 6a; and a sealing protrusion 6c3 integrally connected to the fitting shaft part 6c to seal and hold the inner peripheral surface of the lower end cylinder part 5c over the whole periphery. An annular clearance S1 extended along a direction of an axis O is formed between the sealing protrusion 6c3 and the fitting shaft part 6c. |
