[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring-pull cap with a replacement plug function, and more particularly, to a ring-pull cap that can leave a label on a replacement plug to be used after opening and is easily plugged.

[0002]

2. Description of the Related Art Conventionally, a score is provided on a skirt portion or a skirt portion or a top plate portion in a field of a container lid such as a glass container without using a special opening device such as a bottle opener. A metal cap is widely used in which a score is sheared by pulling a grip portion provided in the metal cap to open the score.

[0003] As such a cap, for example, a pull ring is pulled upward, a score provided at the lower end of a skirt portion of the cap is broken, and the cap is bent at a top plate to open the cap (Japanese Utility Model Publication No. 59-10061). ), And those in which the pull ring is pulled up and the top plate is removed along the score of the top plate (Japanese Utility Model Publication No. 59-40706).

[0004] These caps have the advantage that they can be easily opened. However, since the caps are broken and opened, once they are opened, they cannot be used again. There is a problem that it is inconvenient when the contents are left unreacted. There is also a problem that the contents in the fully filled state at the time of opening are spilled due to the vibration of the opening operation.

[0005] Conventionally, a cap provided with a cap which can be re-opened before opening is also known. For example, a cap having a resin cap over a metal cap as described above is known.

[0006]

However, even in such a cap that can be re-plugged, the one that requires a resin over cap as in the former case is subjected to a normal plugging operation and then the over-cap is removed. It is necessary to cover the overcap portion with a resin film, and the capping operation is troublesome, and there is a problem that the opening operation of the metal cap itself has a structure that easily spills the contents.

Further, in order to leave the label on the cap even after opening, it is necessary to print the display on the resin inner lid,
There is a problem that manufacturing costs are high.

[0008] Accordingly, an object of the present invention is to provide a ring pull with a replacement plug function which can prevent the contents from being spilled when the pull ring is pulled up, can leave a label on the replacement plug, and can reduce manufacturing and plugging costs. To provide a cap.

[0009]

According to the present invention, as a first aspect, a container lid and a resin inner lid provided inside the container lid and shell are provided. A top plate portion and a skirt portion connected to the top plate portion, wherein at the lower end of the skirt portion of the container lid shell, an opening piece is integrally formed. A first weakening line extending at least across the skirt portion along the peripheral portion of the top plate portion or a boundary portion between the top plate portion and the skirt portion is formed, and the first weakening line is formed on the top plate portion of the container lid shell. Has a ring-shaped second weakening line formed so as not to intersect with the first weakening line, and the resin inner lid is surrounded by the second weakening line of the top plate portion. Strongly bonded to parts, but not to other parts of the container lid A cap characterized the door is provided.

According to the present invention, as a second aspect, a container lid shell and a resin inner lid provided inside the container lid shell are provided. A cap having an opening piece integrally formed at the lower end of the skirt portion of the container lid shell, wherein the skirt portion of the container lid shell is provided with both roots of the opening piece. A first weakening line extending upward from the lower end of the skirt portion at each of the portion and a plurality of positions circumferentially spaced from the root portion,
A ring-shaped second weakening line is formed on the top plate portion of the container lid shell, and the resin inner lid is strongly bonded to a portion of the top plate portion surrounded by the second weakening line. Has been
A cap is provided that is non-adhesive to other portions of the container lid shell.

[0011]

In the present invention, the first weakening line is for opening the container lid shell, and the ring-shaped second weakening line is provided on the top surface of the resin inner lid. It is for leaving a part. That is, in any of the caps of the first and second aspects, the first weakening line is easily broken by pulling up the unsealing piece connected to the skirt portion, but the ring-shaped second weakening line is used. Since the top plate section defined by is strongly adhered to the resin inner lid (other parts are not adhered), the second weakened line is simultaneously cut with the first weakened line.
Also easily breaks. Therefore, except for the portion defined by the second line of weakness, the container lid shell is separated from the resin inner lid and removed from the container opening. In addition, the portion defined by the second line of weakness remains in the container opening while being bonded and held to the resin inner lid. Therefore, if a printed portion is given to a portion defined by the second line of weakness, there is no need to give a printed indication to the resin inner lid, and this resin inner lid is used as a replacement stopper as it is. You can do it.
