PROBLEM TO BE SOLVED: To provide a highly sealable container having a cap whose opening/closing torque is small so that even a person of little strength may easily handle it, which does not loose in the courses of distribution and storage, and whose screwing completion position is distinct. SOLUTION: A container main body 100 has a pedestal ring which is provided to the underside of an external thread formed on an outer peripheral surface of a mouth thereof. An engaging protrusion 140 whose right side is formed into a vertical shape in section is provided on an upper face of the pedestal ring at a position of the underside of a lower forward end of the external thread, and a vertical locking protrusion 150 is provided at a predetermined position of the underside of the external thread formed on the outer peripheral surface of the mouth. An inside stopper 200 is provided with an outer sealing ring 220, which has a gap between the outer peripheral surface of the mouth of the container main body and an inner peripheral surface of the outer sealing ring, in a suspended state on the underface of an outer peripheral edge of a top sheet of the inside stopper. A contact sealing ring and an inner sealing ring are provided inside the outer sealing ring in a suspended state. A cap 300 is provided with a notch 340, into which the locking protrusion of the container main body is detachably fitted, at a position located in the vicinity of a lower forward end of an internal thread formed in an inner peripheral face of a peripheral wall of the cap. An engaging protrusion 350, which abuts against the engaging protrusion of the container main body and whose left side is formed into a vertical shape in section, is provided on the underface of the peripheral wall of the cap. |
