Abstract
A hinged-lid pack for delivery systems is disclosed. The pack comprises a base; a lid rotatable about the base between an open and a closed position in which the lid and the base meet at a line of juncture; and a sealing member that bridges the line of juncture and is formed from an amorphous material that is configured to break when the lid is rotated about the hinge into an open position for the first time, to provide a visible indication that the lid has previously been rotated into an open position when the lid is subsequently closed. A method of manufacturing a hinged-lid pack for delivery systems is also disclosed.
