DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for disposing a sealing synthetic resin liner in a container lid shell.

[0002]

2. Description of the Related Art As is well known to those skilled in the art, as a container lid for a container such as a bottle for food and drink, a container lid composed of a container lid shell and a synthetic resin liner has been widely put to practical use. I have. The container lid shell is made of a metal sheet such as an aluminum-based alloy sheet, a chromic steel sheet or a tin sheet, or an appropriate synthetic resin such as polypropylene or polyethylene, and is formed from a top wall which is usually circular and a periphery of the top wall. It has a depending, usually cylindrical, skirt wall. The synthetic resin liner is disposed on the inner surface of the top wall of the container lid shell. The synthetic resin liner is provided with an annular seal portion which is brought into close contact with the mouth and neck of the container.

Usually, the liner made of synthetic resin in the container lid is formed by punching a disk-shaped liner from a synthetic resin sheet molded to a required thickness, and inserting the liner into a required position in the container lid shell. It is arranged by a punch insertion method. Alternatively, it is provided by a so-called embossing method in which a synthetic resin material is supplied to the inner surface of the top wall of the container lid shell and the synthetic resin material is embossed into a required shape.

[0004]

However, when the liner is provided by the punching insertion method, (a) a considerable amount of synthetic resin material remains unnecessarily between the liner punched portions in the synthetic resin sheet. (B) Inevitably, the thickness of the liner must be the same over the entire area of the liner. For example, only the annular peripheral portion which is brought into close contact with the mouth and neck of the container is required. There is a problem that the thickness cannot be reduced, and it is difficult to achieve a sufficiently satisfactory result not only in terms of manufacturing cost but also in terms of sealing characteristics.

On the other hand, in the case of disposing the liner by the embossing method, it is necessary to bring the tip of the sleeve for regulating the flow of the synthetic resin material into contact with the inner surface of the top wall of the container lid shell. For example, the synthetic resin material tends to flow along the inner peripheral surface of the skirt wall of the container lid shell.) Due to this, the outer diameter of the liner is larger than the inner diameter of the top wall relative to the inner diameter of the top wall. It is limited to a value smaller than a predetermined value (for example, in a container lid for a sterile filling container, usually, the outer diameter of the liner is substantially equal to or close to the inner diameter of the top wall of the container lid shell. It is desirable to make this possible).

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and its main technical problem is that a synthetic resin liner of a required form is wastefully consumed on the inner surface of the top wall of the container lid shell. Inexpensive and easy enough without any
