<p>A user can easily separate a cap from a drink container with the small amount of strength. A fluid flow passage (8) is formed inside a cap main body (11), and a valve body (21) applying power to a direction closing an entrance (15) of the fluid flow passage is installed. A cover (25) for closing an upper opening of the cap main body (11) is formed on the upper side of the cap main body (11), and an operation lever (24) for opening and closing the valve body (21) is installed on the cover (25) to press the lever downwards. A combination protrusion (53) is installed on an elastic piece (52) of the cap main body (11), and a horizontal upper surface (54U) is installed on the cover (25) to be combined to the combination protrusion. The operation lever (24) includes a protrusion piece (58) which contacts the elastic piece (52) when a user presses the operation lever (24) downwards, and moves the elastic piece (52) to the combination release direction. The combination of the combination protrusion (53) and the horizontal upper surface (54U) is separated by the protrusion piece (58) of the operation lever (24) when the user presses the operation lever (24) downwards, and power is applied to the operation lever (24) to the upper direction by the valve body (21) for the user to easily remove the cover (25) from the cap main body (11).</p> |
