A suitable heat effect agent may be, but is not limited to, vanillyl ethyl ether and a suitable cooling agent may be, but not limited to eucalyptol, WS-3. Figure 1 illustrates a hinged-lid pack 1 according to an embodiment of the invention. The pack 1 comprises a base 2 and a lid 3 hingedly connected to the base 2 along a hinge line (not shown) formed in a rear wall of the pack 1 in order to allow the pack to be opened and closed. When the lid 3 is in a closed position, the lid 3 meets the base 2 at a line of juncture 4 that extends from each end of the hinge line in respective side walls 5 of the pack 1 and across a front wall of the pack 1. The line of juncture 4 separates each side wall 5 into a lid portion 6 and a base portion 7. Figure 2 illustrates the pack 1 shown in Figure 1 with the lid in the open position. It will be appreciated that the base 2 forms a delivery system receiving space in which delivery systems 8 (shown in Figure 2) such as smoking articles or other tobacco industry products are received and stored. The delivery systems 8 are accessible when the lid 3 is in an open position, and the delivery systems 8 are retained in the delivery system receiving space when the lid 3 is in a closed position. Typically, the delivery systems 8 are wrapped in a bundle 9 (shown in Figure 2). Only at least one side wall 5 comprises a line of weakness 10 between the lid portion 6 and the base portion 7. In some embodiments, only each side wall 5 of the pack 1 comprises a line of weakness 10. It is to be understood that the term “only at least one side wall” or “only each side wall” means that the line of weakness 10 is only present in either one of the side walls 5 or both side walls 5. In other words, there is no line of weakness across the front wall of the pack between the lid and the base. The line of weakness 10 is configured to be broken to allow the lid 3 to be rotated about the hinge line into an open position for the first time. Thus, the line of weakness 10 provides an indication that the lid 3 has previously been rotated into an open position when the lid

[0053] 3 is subsequently closed. In other words, the line of weakness 10 acts as a tamper evidence feature. In some embodiments, the line of weakness 10 is configured to provide audial or resistive feedback when the lid 3 is rotated about the hinge line into an open position for the first time. In the embodiment shown in Figure 2, the line of weakness 10 is in alignment with the line of juncture 4 when the lid 3 is in a closed position.

[0054] In some embodiments, the line of weakness 10 comprises a tear tape formed in the at least one side wall 5 of the pack 1. It is to be appreciated that the tear tape may comprise a tab to enable tearing of the tear tape. When the line of weakness 10 comprises a tear tape, a consumer is unable to open the pack 1 until the tear tape is removed. Once removed, the consumer is able to rotate the lid 3 into an open position. Additionally, once removed from the pack 1, it is clear to a consumer that the pack 1 has been previously opened as the tear tape leaves a gap between the lid portion 6 and base portion 7 of the side wall 5. Alternatively, the line of weakness 10 may be formed from perforations in the material of the pack 1.

[0055] Figure 3 illustrates a hinged-lid pack according to another embodiment of the invention. Here, the at least one side wall 5 comprises a tab 11. The tab 11 is fixed to an inside surface of the lid portion 6 and base portion 7 of the at least one side wall 5. In other embodiments, each of the side walls 5 comprises a tab 11. Figure 4 shows the pack 1 of Figure 3 with the lid 3 in the open position. As seen, the line of weakness 10 is formed in the tab 11. When the lid 3 is rotated into an open position for the first time, the tab 11 breaks along the line of weakness 10 and provides an indication that the lid 3 has previously been rotated into an open position when the lid 3 is subsequently closed. A portion 12 of the tab 11 is fixed to the inside surface of the base portion 7. Another portion 13 of the tab 11 is fixed to the inside surface of the lid portion 6. The portions 12, 13 of the tab 11 may be fixed to the lid portion 6 and base portion 7 by any suitable means. Preferably, the tab 11 is fixed to an inside surface of the lid portion 6 and base portion 7 via a permanent adhesive. It is to be appreciated that the tab 11 is fixed to the lid portion 6 and base portion 7 such that when the lid 3 is rotated about the hinge line for the first time, the portions 12, 13 of the tab 11 remain attached to the inside surface of the lid portion 6 and base portion 7 and therefore the tab 11 breaks along the line of weakness 10.

[0056] As seen in Figure 4, the line of weakness 10 in the tab 11 is spaced from the line of juncture 4. Therefore, when the lid 3 is in the open position, a part 14 of the tab 11 protrudes from the base portion 7. In an alternative embodiment shown in Figure 5, the line of weakness 10 is spaced from the line of juncture 4 such that a part 14 of the tab 11 protrudes from the lid portion 6 when the lid 3 is in the open position. In some embodiments, the part 14 of the tab 11 which protrudes from the lid portion 6 or base portion 7 when the lid 3 is in the open position is provided with indicia. The indicia may communicate information to a consumer, such as a message stating that the pack 1 has been previously opened.

[0057] Furthermore, it is to be appreciated that as an alternative, the tab 11 may be fixed to an outside surface of the at least one side wall 5. In an embodiment such as this, it is more obvious to a consumer that the pack 1 has been previously opened as the broken tab is external to the pack 1 and thus visible to a consumer.

[0058] Figure 6 illustrates a flow chart showing method steps of a method of manufacturing a hinged-lid pack according to embodiments of the invention. The method comprises a first step Si of providing a base and a lid rotatable relative to each other about a hinge line formed in a rear wall of the pack between open and closed positions. The lid and the base meeting in a closed position at a line of juncture that extends from each end of the hinge line in respective side walls and separates each side wall into a lid portion and a base portion. The method comprises a second step S2 of forming a line of weakness in at least 1 side wall between the lid portion and the base portion that breaks to allow the lid to be rotated about the hinge line into an open position for the first time to provide an indication that the lid has previously been rotated into an open position when the lid is subsequently closed. The second step S2 of forming the line of weakness may comprise aligning the line of weakness with the line of juncture when the lid is in the closed position. As described above, the line of weakness may comprise a tear tape formed in the at least one side wall. The tear tape may comprise a tab to enable tearing of the tear tape.

[0059] In some embodiments, the method further comprises a third step S3 of providing at least one side wall with a tab, or alternatively, providing each side wall with a tab. Additionally, the method may further comprise a fourth step S4 of fixing the tab to an inside surface of the base portion and the lid portion. In this case, the second step S2 of forming the line of weakness may comprise forming the line of weakness in the tab such that the tab breaks when the lid is rotated about the hinge line into an open position for the first time to provide an indication that the lid has previously been rotated into an open position when the lid is subsequently closed. Furthermore, the fourth step S4 of fixing the tab to an inside surface of the base portion and lid portion may comprise fixing a portion of the tab to the inside surface of the base portion and fixing another portion of the tab to the inside surface of the lid portion. Moreover, this fourth step S4 may also comprise fixing the tab via a permanent adhesive.

[0060] In some embodiments, the second step S2 of forming the line of weakness comprises spacing the line of weakness from the line of juncture such that a part of the tab protrudes from the base portion or lid portion when the lid is in the open position. The method may comprise a fifth step S5 of providing the part of the tab protruding from the base portion or lid portion with indicia.

[0061] Finally, the method may comprise a sixth step S6 of configuring the line of weakness to provide audial or resistive feedback when the lid is rotated about the hinge into an open position for the first time.
