<p>A sealed container configured in such a manner that the cap is effectively prevented from loosening without increasing the size of a fastening member. A sealed container in which a container body (2) and a cap (3) which closes the opening provided in the container body (2) are connected together through screw threads, wherein a screw thread ridge (4) provided on the container body (2) side and a screw thread groove (5) provided on the cap (3) side are configured to be engageable with each other. The screw thread groove (5) has wide groove sections (5a, 5b), the width of which in the circumferential direction is locally large, and also has a high protrusion section (12a) which, when the container body (2) and the cap (3) are rotated relative to each other in the circumferential direction, increases the tightening force between the container body and the cap or/and generates a clicking sensation. When the cap (3) is tightened onto the container body (2) along the direction of the lines of the screw thread ridge (4) and the screw thread groove (5), the screw thread ridge (4) enters into the wide groove sections (5a, 5b), and the cap (3) and the container body (2) are rotatable relative to each other in the circumferential direction.</p> |
