Abstract (en)
A container is formed of sheet material and has an opening to enable access to be gained to the interior of the container. The container includes a flap portion and a layer of adhesive for adhering the flap portion to another portion of the container to close the opening. The adhesive is associated with a solvent-soluble dye wherein any attempt to gain access to the interior of the closed container by treating the adhesive with such a solvent results in dissolution of the dye and the resultant dye solution causes staining which makes it visibly apparent that said attempt has been made. An adhesive layer may be provided on both of said portions.
