2. Description of the Related Art Juice, sake, soft drinks, etc. are often stored in containers such as glass bottles and plastic bottles, and sealed by screwing a metal screw cap (or screw cap) into the opening of the head. Is done. In order to prevent the screw cap of the container from being loosened even when a strong vibration is applied during distribution or transportation, the screw cap is tightened considerably at the opening of the container at the stage of shipping. Therefore, it is necessary to grip and rotate the screw cap with strong force to open it, and it is difficult for women, children, or elderly people to open the screw cap directly by hand. Often.

[0003] To solve this problem, Japanese Unexamined Utility Model Publication No. 5-77097 has proposed an opening tool for easily opening the screw cap of the container. As shown in FIG. 5, in this opening device, a metal plate 31 is integrally connected to the tip of a handle 36, one end of the metal plate 31 is bent to form a fixed lid holder 33, and the other end is similarly bent. A spiral round bar 34 having a handle 35 is screwed therethrough, and a movable lid holder 32 is pivotally supported at the tip of the spiral round bar 34 so as to be freely rotatable. To open the screw cap with this opening tool, first hold the handle 36 with one hand, position the opening tool so that the screw cap is inserted between the fixed cap holder 33 and the moving cap holder 32, and use the dominant finger. The handle 35 is pinched and rotated until the movable lid holder 32 is strongly pressed against the side surface of the screw lid, and the screw lid is tightened between the fixed lid holder 33 and the movable lid holder 32 to be gripped and fixed. Next, in this state, the handle 36 is changed to a dominant hand, and the screw cover is opened by turning the handle 36.

[0004]

However, the above-mentioned opening device is
Since the spiral round bar 34 for moving the movable lid holder 32 is provided in addition to the handle 36, there is a problem that the number of parts increases. Also, a handle 3 for fixing the screw cap to the opening device.
Since the operation of Step 5 must be performed with a finger, it is necessary to apply a considerably strong force to the finger in order to firmly tighten the screw cap and securely hold the opening device. Therefore, there is a problem that it is difficult for a person with a weak finger to securely fix the screw cap. Further, when the screw cap is tightly closed, it is necessary to re-hold the handle 36 with the hand of the dominant arm to rotate the screw cap, but since this opening tool has the handle 35 and the handle 36 separately, Since the hand of the dominant arm that operated the handle 35 must be temporarily changed to the handle 36 and then rotated, the operation is troublesome. Accordingly, an object of the present invention is to provide a new screw lid opening tool that solves such a problem.
