[0050] Figure 1 shows a hinge-lid pack 1 for a delivery system according to one embodiment of the present invention. Pack 1 comprises a base 2 and a lid 3 hingedly connected to base 2 along hinge 4 to enable the pack to be opened and closed. Base 2 comprises a base front wall 5 and lid 3 comprises a lid front wall 6. Lid front wall 6 and base 2 meet at a join line 7 when lid 3 is in the closed position.

[0051] It will be appreciated that the base 2 forms a delivery system receiving space in which a delivery system 8, such as a smoking article or other tobacco industry product, is received and stored. The delivery system 8 is accessible when the lid 3 is in the open position, and the delivery system 8 is retained within the delivery system receiving space when the lid 3 is in the closed position. Typically, the delivery system 8 is wrapped in a bundle 9.

[0052] The lid front wall 6 includes a lid front wall flap 10 extending from the lid front wall 6 and attached to the base 2. As seen in FIG. 1 , the lid front wall flap 10 has a width equal to the width of the base front wall 5. It should be understood that in other embodiments, the lid front wall flap 10 may have a width less than the width of the base front wall 5. The lid front wall flap 10 is integrally formed with the lid front wall 6. A portion of the lid front wall flap 10 is secured to the inner surface of the base front wall 5. Alternatively, the entire lid front wall flap 10 is secured to the inner surface of the base front wall 5. In yet other embodiments, the lid front wall flap 10 is attached to the outer surface of the base front wall 5. The lid front wall 6 and the lid front wall flap 10 are separated by a line of weakness 11. The pack 1 is configured such that when the lid 3 is rotated to the open position for the first time, the lid front wall 6 and the lid front wall flap 10 separate along the line of weakness 11, indicating that the package 1 has previously been opened.

[0053] As seen in FIG. 1 , the line of weakness 11 is linear. However, it should be understood that the line of weakness 11 may be non-linear. A linear line of weakness is advantageous because it is easier to manufacture. Additionally, a linear line of weakness maximizes the continuous space on the pack that can be used to present information to the consumer. Alternatively, a non-linear line of weakness may be easier to open because it intuitively tears from one end of the line of weakness to the other. Additionally, the line of weakness 11 may be configured to provide auditory or resistance feedback to the consumer opening the package 1 for the first time.

[0054] In some embodiments, the line of weakness comprises a tear tape formed between the lid front wall 6 and the lid front wall flap 10. It should be understood that the tear tape may comprise a tab to allow for tearing of the tear tape. When the line of weakness 11 comprises a tear tape, the consumer cannot open the pack 1 until the tear tape is removed. Once removed, the consumer can rotate the lid 3 to the open position. Furthermore, once removed from the pack 1, it is apparent to the consumer that the pack 1 has previously been opened as the tear tape leaves a visible gap.

[0055] FIG. 1 shows pack 1 with lid 3 in the open position. Thus, lid front wall 6 and lid front wall flap 10 are already separated along weakened line 11. In this embodiment, weakened line 11 is aligned with bond line 7. Thus, lid front wall flap 10 remains behind base front wall 5 and is not visible to the consumer when pack 1 is first opened. Lid front wall flap 10 is secured within base 2 by any suitable means to ensure that lid front wall flap 10 separates from lid front wall 6 along weakened line 11 when lid 3 is first rotated to the open position. In other words, the strength of the connection between lid front wall flap 10 and the inner surface of base front wall 5 is greater than the force required to break weakened line 11. Lid front wall flap 10 may be permanently secured to the inner or outer surface of base front wall 5 by any suitable means, such as a permanent adhesive area.

[0056] Figure 2 shows another embodiment of a hinge-lid pack 1 according to the present invention, where the line of weakness 11 is spaced from the line of joinder 7. Thus, when the lid 3 is first rotated to the open position and the line of weakness 11 separates, a portion 12 of the front lid wall flap 10 extends beyond the lower edge of the front lid wall 6. The portion 12 of the front lid wall flap 10 that extends from the front lid wall 6 may be provided with indicia to communicate information to the consumer.

[0057] Figure 3 shows another embodiment of a hinge-lid pack 1 according to the present invention. Here, the lid front wall flap 10 is not integral with the lid front wall 6, but is attached to the lid front wall 6 by any suitable means, such as with an adhesive. The adhesive is preferably of a permanent type so that the lid front wall flap 10 does not separate from the lid front wall 6 when the pack 1 is opened. Furthermore, the lid front wall flap is attached to the inner surface of the base front wall 5.

[0058] When the lid 3 is first opened, the lid front wall flap 10 separates along the weakened line 11. As can be seen in Figure 3, a portion 13 of the lid front wall flap 10 extends beyond the upper edge of the base front wall 5. The portion 13 of the lid front wall flap 10 that extends from the base may include indicia to communicate information to the consumer.

[0059] 4 is a flowchart illustrating method steps for manufacturing a hinge-lid pack for a delivery system according to one embodiment of the present invention. The method includes a first step S1 of providing a base and a lid that is rotatable about the base between open and closed positions. The lid includes a front lid wall that forms a line of junction with the base when the lid is in the closed position. Second and third steps S2 and S3 of the method include providing a front lid wall flap extending from the front lid wall and securing the front lid wall flap to the base, respectively. Finally, the method includes a fourth step S4 of providing a line of weakness in the front lid wall and the front lid wall flap that is configured to separate when the lid is first rotated to the open position.

[0060] In some embodiments, the third step S3 of securing the lid front wall flap to the base includes securing the lid front wall flap to an inner surface of the base front wall. Alternatively, the third step S3 includes securing the lid front wall flap to an outer surface of the base front wall.

[0061] The method may include a fifth step S5 of aligning the line of weakness with the line of bond. Alternatively, the fifth step S5 may include spacing the line of weakness from the line of bond such that when the lid is rotated to the open position for the first time and the line of weakness separates, a portion of the lid front wall flap extends beyond the upper edge of the base front wall. Furthermore, as another alternative, if the lid front wall flap is integrally formed with the lid front wall, the fifth step S5 may include spacing the line of weakness from the line of bond such that when the lid is rotated to the open position for the first time and the line of weakness separates, a portion of the lid front wall flap extends beyond the lower edge of the lid front wall.

[0062] Additionally, the method may include a sixth step S6 which includes providing indicia on the portion of the lid front wall flap that extends from the base or lid.
