Abstract
In connection with an information transmission member-equipped external member (outer lid member) to be mounted on a container lid, the opening of the container lid and the destruction of the information transmission member are carried out by a series of operations. Upon rotational movement of an opening/closing cover (3) and an outer cover (4) relative to each other, the opening/closing cover (3) is raised to destroy a predetermined site of an IC tag (40), and a tamper-evident bottom section (38) is cut off, whereby the outer cover (4) is separated from the opening/closing cover (3), and the opening/closing cover (3) is opened sideways to make the opening/closing cover (3) detachable from the container lid.
Claims9
An external member for a container lid, comprising:
- an opening/closing cover which covers an upper surface and an outer peripheral surface of the container lid, which can be opened sideways, and which has a locking section formed on an inner peripheral surface thereof for restraining an upper movement thereof by engaging the container lid or a container when the opening/closing cover is in a closed state;
- an outer cover which covers an upper surface and at least an upper side of an outer peripheral surface of the opening/closing cover, and which has a tamper-evident bottom section to be locked by a restraint section of the opening/closing cover when the opening/closing cover is in the closed state;
- and
- an information transmission member to be mounted on one of the opening/closing cover and the outer cover,
- wherein the tamper-evident bottom section is cut off upon rotational movement of the opening/closing cover and the outer cover relative to each other, whereby the outer cover is separated from the opening/closing cover, and the opening/closing cover is opened sideways to make the opening/closing cover detachable from the container lid.
An external member for a container lid, which is an opening/closing cover, wherein
- the opening/closing cover includes a top panel covering an upper surface of the container lid, and a peripheral wall extending downwardly from an outer peripheral part of the top panel to cover a peripheral surface of the container lid,
- the opening/closing cover has a vertically extending hinge portion formed in a partial peripheral wall part of the peripheral wall, whereby the opening/closing cover can open sideways about the hinge portion as a rotation center, and
- the opening/closing cover has a locking section formed on an inner peripheral surface of the peripheral wall, the locking section engaging the container lid or a container when the opening/closing cover is in a closed state.
