（例えば実開昭５８−６７７６０号公報参照）。2. Description of the Related Art Conventionally, as a pull-off cap of this type, a sealing film part is connected to a closed part which is closed annularly at a portion near the upper end opening of a cylindrical cap body through a cut part. Various proposals have been made (see, for example, Japanese Utility Model Laid-Open No. 58-67760) in which the sealing film portion is provided and the sealing film portion is cut and opened along the cut portion via a pull ring.

プルオフキャップと実質的に異なるところがない。The pull-off cap according to the present invention is injection-molded by using, for example, polypropylene, and as shown in FIG. 1, a sealing film portion 2 for sealing a spout of a cylindrical cap body 1.
Is connected to the lower end of a tubular closing portion 3 that annularly closes the peripheral portion of the upper end opening of the main body 1 via a cut-off portion 4, and on the upper surface side of the sealing film portion 2. The pull rings 5 are continuously arranged in a substantially concentric arrangement via a connecting portion 6 that extends from a part of the circumference of the ring 5. The above structure is substantially the same as the conventional pull-off cap.

７を設け構造を強化している。According to the present invention, in the pull-off cap having the above structure, the closing portion 3 is provided with a reinforcing rib 7 so that the closing portion 3 is not deformed even if it receives a relatively large opening operation force during the initial opening operation. There is.
【００１４】補強リブ７による閉鎖部３の構造強化状況
が図１の左側上部と図３とに示されてる。The structural reinforcement of the closure 3 by the reinforcing ribs 7 is shown in the upper left part of FIG. 1 and in FIG.
