  • Can
    Patent number: 7198168
    Abstract: A can (1) having a spout that can, after opening, be securely resealed and can be opened and closed with an easy operation. The can (1) has a spout (3) that is opened by lifting and pulling a pull-ring (6) fixed on a top wall (2) of a can body (1a) with a rivet (5) to bend a sealing tongue portion (4) toward the inside of the can. Inside the top wall (2) and away from the spout (3), an internal sealing member (7) having a fan shape with its pivot mounted to the rivet and a size capable of sealing the spout (3) is disposed so as to be fixed to the rivet (5). After opening the spout (3), by rotating the pull-ring (6) around the rivet (5), the internal sealing member (7) is also rotated at the same time. As an interlocking mechanism therefor, the rivet (5) is rotatably supported by the top wall (2), and a base end of the pull-ring (6) and the pivot of the internal sealing member (7) are fixed to the rivet (5), respectively.
