つて防止するための構造を与えられていない。 The container lid disclosed in Japanese Unexamined Utility Model Publication No. 56-49753 is equipped with an opening history display band that allows confirmation of whether the lid has been opened in the past. The indicator band itself is not intended to prevent the lid from being removed from the container. The container lid consists of a disc-shaped metal cover and a plastic ring having a cylindrical skirt, but the metal cover and plastic ring are not molded as a single piece; After manufacturing each member individually, they are formed by combining them. This structure, which cannot be integrally molded, is disadvantageous from the viewpoint of keeping the manufacturing cost of the container low. In addition, the band for the container lid shown in the publication is not intended to resist external force to prevent the lid from coming off the container due to its function as an interference indicating band, but rather to prevent the lid from coming off during transportation. No structure is provided to prevent this by the engagement relationship between the container and the container.

の目的とする。 The present invention was devised against this technical background, and is capable of preventing the lid from coming off during transportation due to the reliable engagement relationship between the closure band and the container. As stated in the introduction, the lid and container can be manufactured efficiently and economically by die-casting, and the lid can be easily removed by tearing off the locking band. The aim is to improve closure devices.

る。Means and operation for achieving the object The object is a closure device for a plastic container with a lid, the plastic container being a shaped body which is open at its upper end and has a peripheral wall and a bottom wall; On the outside, the lid has a plurality of retaining protrusions spaced apart from one another in the circumferential direction, a closure element surrounding and engaging the upper circumferential wall of the container, and a closure element adjoining the closure element. A structure that has a circumferential groove and a closure band, and the outer wall of the closure element has a plurality of openings corresponding to the retention protrusions, and the lid is closed by the engagement relationship between the closure band and the retention protrusions. In the closure device of
The upper circumferential wall of the container has a thickened portion at its upper end, the lid has a tightening circumferential rib that engages the back of the thickened portion, and the closure band is a tear-off band integrally formed with the lid. This is achieved by providing a plastic container closure device in which the closure band has a plurality of locating grooves located below the opening and aligned with the container retaining projections.

と係合し、もつて蓋によつて容器が閉鎖される。
その際、蓋の締め付け周回リブが容器周壁上端の
厚肉部に係合する。 In such a configuration, when the lid is attached to the container for the first time, the lid is first applied to the upper end of the peripheral wall of the container. In this operation, it is not necessarily necessary to position the lid in the circumferential direction. This is because when the lid placed on the container is slid and rotated in the circumferential direction, each holding protrusion engages with the positioning groove, thereby correctly positioning the lid with respect to the container. When the lid is then pressed downwards, i.e. towards the bottom wall of the container, the relative displacement between the retaining projection of the container and the lid causes the retaining projection to enter into the opening of the closure element above the positioning groove and to The retaining projection engages the closure band, thereby closing the container with the lid.
At this time, the tightening circumferential rib of the lid engages with the thick portion at the upper end of the container peripheral wall.

式)蓋の装着と同じである。 To remove the attached lid from the container, the closure band, which is a tear-off band, is first torn off. By breaking the closure band, the engagement between the retaining projection and the closure band is released, and the lid can be removed from the container. Next, when the lid is moved in a direction away from the container, the tightening circumferential rib of the lid disengages from the thick portion at the upper end of the peripheral wall of the container, and the lid is removed. After the closure band is broken, the lid can be reattached by utilizing the engagement relationship between the tightening circumferential rib of the lid and the thick portion at the upper end of the container peripheral wall. This is the same as installing a regular snap-on lid.
