<p>The present invention relates to a device to open a screw cap by one hand and, specifically, to a device provided to open a screw cap of various types of bottles by one hand by opening and closing an air hole of a rubber absorption plate. Air freely comes in and out of the device by turning a lever (20) to the right as much as possible, while the air is blocked by turning the lever (20) to the left as much as possible. When a water bottle equipped with the device is opened, a cap is turned to the left to block air to increase friction of an absorption rubber (30) having holes formed on the bottom and the center thereof, thereby easily being opened by one hand. The bottle attached with the device allows user to turn the cap back to the right side to smoothly flow air and open the cap to drink water, and reduces friction between the absorption rubber (30) and the bottom to easily be removed from the bottom. The device is provided to solve the problems of the disable person who can only use one hand and has difficulties in opening a screw cap.</p> |
