等が有る。As shown in FIG. 5, this type of tamper-evident display lid has a rupture-removed portion 51 formed on an outer lid side wall 33, and is formed on an outer side of a spout wall 16 or the like formed on a lid body 11 which is an inner lid. The inwardly projecting portion 34 engaging with the outwardly projecting portion 19 formed in
The outer lid 31 is formed in such a manner that the outer lid 31 cannot be opened unless the rupture-removed portion 51 is removed by tearing with the handle portion 53 when opening the outer lid 31 (for example, the actual opening 58). −3.
No. 463, a protective cover is provided to cover the unsealing protrusion 35 for pushing up the outer lid 31 when the outer lid 31 is opened, and the side wall 13 of the lid body serving as an inner lid is provided by a bridge or the like.
The protective cover is removed from the main body of the lid by breaking the bridge when the outer lid is opened, so that the opening projection can be pushed up (for example, see
No. 62-78.064), and furthermore, a minute projection is formed immediately below the opening projection, and a hook which can be broken and removed is formed on the side wall of the lid body. That the latching portion is to be broken from the lid body when the outer lid is opened by engaging with the lid (eg, Japanese Utility Model Application Laid-Open No. 63-21.252).
And so on.
