ている。As is well known, as a container lid applied to the mouth and neck of a glass or synthetic resin container for soft drinks, a shell formed from a relatively hard synthetic resin such as polypropylene or hard polyethylene. A synthetic resin container lid composed of a liner formed of a relatively soft synthetic resin such as soft polyethylene or EVA (ethylene-vinyl acetate copolymer) has been widely put into practical use. The shell has a top wall and a skirt wall depending from a peripheral edge of the top wall, and the liner is disposed on an inner surface of the top wall of the shell.

イナーが直接的に形成される。Usually, the synthetic resin shell of the container lid is molded by compression molding or injection molding. On the other hand, the synthetic resin liner is formed by punching a synthetic resin sheet having a required thickness into a disc shape, and then inserted into the inner surface of the top wall of the shell. Alternatively, a synthetic resin material in a softened and molten state is supplied to the inner surface of the top wall of the shell, and the synthetic resin material is embossed into a liner having a required shape, whereby the liner is directly formed on the inner surface of the top wall of the shell.

れている。Further, in JP-A-64-84860, a liner is molded by injection molding, and then the molded liner is used as a so-called insert member to mold a shell by injection molding. A method and apparatus for manufacturing a synthetic resin container lid comprising a liner and an injection molded synthetic resin shell is disclosed.

足し得る結果を達成することが困難である、という問題
がある。Therefore, in the method of punching out the liner from the synthetic resin sheet, a considerable amount of the synthetic resin material is wastefully left between the liner punching portions of the synthetic resin sheet. Due to this, the manufacturing cost is high.Therefore, it is inevitable that the liner has the same thickness over the entire area.For example, only the annular peripheral portion that is in close contact with the mouth and neck of the container can be made thicker. No
There is a problem that it is difficult to achieve sufficiently satisfactory results not only in terms of manufacturing cost but also in terms of sealing characteristics.

It is necessary to bring them into contact with each other (otherwise, so-called bleeding occurs in which the synthetic resin material flows along the inner peripheral surface of the skirt wall of the shell), and this causes the outer diameter of the liner to increase. Is limited to a value smaller than the inner diameter of the shell by a predetermined value or more (for example, in a container lid for an aseptic filling container, generally, the outer diameter of the liner is substantially the same as or smaller than the inner diameter of the top wall of the shell. It is desirable that the value be close to this.

い。In the synthetic resin container lid manufacturing apparatus of the present invention, since the liner is compression-molded by the rotary liner compression-molding means, the liner having the required shape can be sufficiently inexpensively manufactured without wasting the synthetic resin material. Molding can be performed with sufficiently high molding efficiency and speed. Further, since the molded liner is carried into the shell compression molding means and the shell is compression molded by being associated with the liner, the outer diameter of the liner can be made substantially the same as the inner diameter of the top wall of the shell if necessary. be able to. Since the molding of the shell is performed by the rotary shell compression molding means, the molding efficiency and speed are sufficiently high. Since transfer of the liner from the liner compression molding means to the shell compression molding means is performed by the rotary liner transfer means, the molding efficiency or speed is not reduced due to the transfer of the liner.

構成の詳細についての説明は省略する。Continuing the description with reference to FIG. 11, in the container lid discharge area 42, the upstream end of the discharge chute 46 is positioned between the lower mold part 72 and the upper mold part 74. Then, the intermediate annular member 82 and the central punch member 84 of the upper die portion 74 of the shell forming die mechanism 34 are raised with respect to the outer annular sleeve member 80 of the upper die portion 74. In the container lid 98 including the shell 88 and the liner 62, the lower end surface of the outer annular sleeve 80 has the shell 88.
Of the central punch member 84 is connected to the pressurized air source and the pressurized air is discharged from the annular vent hole 86. , Intermediate annular member 82 and central punch member 8
4 is prevented from ascending and thus is disengaged from the intermediate annular member 82 and the central punch member 84, FIG.
As shown by the two-dot chain line in FIG. 1, it is made to fall on the upstream end of the discharge chute 46. The container lid 98 dropped on the discharge chute 46 is conveyed through the discharge chute 46 to, for example, a break line forming area (not shown). In the break line forming region, a circumferential break line (not shown) extending in the circumferential direction is formed on the skirt wall 92 of the shell 88 of the container lid 98, and the skirt wall 92 has the female screw on the inner surface thereof. It is divided into a main portion having the ridges 94 and a tamper-evidence hem portion having the locking flap pieces 96 formed on the inner surface thereof, thus completing a synthetic resin container lid having tamper-evidence characteristics. . The form of the container lid itself is substantially the same as that of the conventional container lid, and therefore, the detailed description of the configuration of the container lid itself is omitted in this specification.

Although it is directly supplied from the compression molding unit 2 to the shell compression molding unit 6, if desired, for example, the liner 62 molded by the liner compression molding unit 2 is once collected in a hopper or the like,
After that, the hopper may be supplied to the shell compression molding means 6 via the liner transfer means 4. Also, for the purpose of sales promotion, print a prize such as hitting on one surface of the liner (the surface that comes into contact with the inner surface of the top wall of the shell), and peel off the liner from the shell so that the prize can be identified. Is desired, for example, a through opening is formed in the liner receiving portion of the liner transfer means, and the liner positioned on the liner receiving portion is passed through the through opening when being conveyed toward the liner loading area. The prize can be printed by applying printing ink to the central portion of the lower surface of the liner exposed downward.
