[Problem] To provide a single-touch-opening cap that is attached to a bottle, by which a lid can be opened by a single-handed operation, and by which opening of the lid by erroneous operation can be prevented. [Solution] Provided is a single-touch-opening cap characterized by comprising the following: a base provided with a linking means that links to a bottle, a ring that is disposed at a gap from the linking means but connects to a portion of the linking means, and that deforms such that a tip projects forward by a pressing force from left and right, and a latching unit provided on the tip of the ring; and a lid unit comprising a body that is rotatably provided on the base and that covers a nozzle when closed, and a tab that is provided on the body and that latches onto the latching unit when closed. The single-touch-opening cap is also characterized by the ring deforming by being pressed from left and right, thereby releasing the tab from the latching unit and rotating the rid unit to open the nozzle.
