2. Description of the Related Art A metal can container provided with an easy-open can lid (easy open end) used for canning beverages containing beverages is fastened around an opening at an upper end opening of a can body. In the center of the can lid, a mouth closed by a central panel portion is integrally formed so as to protrude above the peripheral winding portion, and is surrounded by an upper end surface of the mouth portion and is higher than the upper end surface. A substantially circular weakened portion (score) that can be broken except for a portion serving as a hinge portion is formed in the central panel portion that is recessed downward, and the weakened portion extends along the portion that becomes a spout. A structure that is formed on the lowermost layer of an annular layered portion in which the portion is folded three times and is covered with a resin from the inner surface side of the can lid has been conventionally known (for example, US Pat. No. 4,976,368). No., etc.).

By the way, in the above-mentioned can container with a resealing cap (beverage can with a resealing cap) as described above, the cap is attached to the mouth of the can lid (head of the beverage can). In this case, it is necessary to first attach the cap body to the mouth of the can lid (head of the beverage can), and then fit a reinforcing ring from above the cap body. When removing the cap from the part (head of the beverage can), it is necessary to first remove the reinforcing ring from the cap body, and then remove the cap body from the mouth of the can lid (head of the beverage can). Thus, the operation of attaching and detaching the cap to and from the can container (beverage can) is troublesome.

Further, since the top wall itself of the cap body is easily elastically deformed by forming the pressing portion for the opening operation, when the reinforcing ring is fitted and the outer periphery of the cap body is strongly tightened, Due to the reaction, the top wall of the cap body tends to lift upward, so that the close contact between the upper end surface of the can lid (top surface of the head of the beverage can) and the inner surface of the top wall of the cap body is loosened. There is a danger of the beverage leaking from the gap, and even if packing is mounted on the inner surface of the top wall of the cap body, the beverage may leak from the gap between the can lid and the cap body if the can container falls over.

On the other hand, since a pressing portion for opening operation is formed on the top wall itself of the cap body, even if the pressing portion is strongly pressed, the movable range in the vertical direction is small, The central point of the lower surface of the part is used as a contact piece, and this contact piece pushes down the central point of the opening piece (press-down tab) of the can lid, so that the pressing force of the finger breaks the score. It is difficult to effectively act as a force for pushing down the opening piece (pressing tab). As a result, a large force is required for the opening operation through the cap body.

That is, since the pressing portion is formed on the top wall itself of the cap main body, the more the pressing portion is easily elastically deformed and has a large movable range, the inner surface of the top wall of the cap main body and the can lid are formed. Of the top of the mouth (top of the beverage can) and the likelihood of leakage of the beverage increases, and conversely, the inside of the top wall of the cap body and the top of the mouth of the can lid ( In order to ensure the state of close contact with the top of the beverage can, the pressing portion of the cap body is unlikely to be elastically deformed, requiring a large force to open the spout.
