Hinged lid pack

Abstract

A hinged lid pack (2) for a delivery system is disclosed. The hinged lid pack comprises a base (3) and a lid (4) that is rotatable with respect to the base between an open position and a closed position about a hinge (5) defined by a discontinuity line (6) around which the pack material folds. When the lid is first rotated to the open position about the hinge, the pack material is folded such that the discontinuity line becomes a continuity line, providing a visual indication that the lid was previously in the open position when the lid is subsequently closed. Also disclosed is a hinged lid pack for a delivery system comprising a region (15) demarcated by a fragile line (16). The fragile line is configured to break when the lid is first rotated to the open position about the hinge line, such that the region separates from the pack and a window (17) is formed in the pack material, providing a visual indication that the lid was previously in the open position when the lid is subsequently closed.

[0047] Figure 1 shows a standard hinged lid pack. Pack 2 comprises a base 3 and a lid 4 hinged to the base 3 along a hinge 5 to allow the pack to be opened and closed. It will be understood that the base 3 forms a delivery system containment space in which a delivery system, such as smoking products or other tobacco industry products, is received and stored. The delivery system is available when the lid 4 is in the open position, and the delivery system is held within the delivery system containment space when the lid 4 is in the closed position.

[0048] Figure 2A shows a blank 1 of a hinged lid type pack according to one embodiment of the present invention. As shown, the hinge 5 is defined by a discontinuous line 6 around which the material 7 of the pack 2 folds. The pack 2 is formed from a material 7, such as cardboard, which creases when folded. Thus, when the lid 4 is first rotated to the open position around the hinge 5, the material 7 of the pack 2 creases, and the discontinuous line 6 becomes a continuous line 8 (shown in Figure 2C), providing a visual indication that the lid 4 was previously in the open position when the lid 4 is subsequently closed.

[0049] Figures 2B and 2C are detail views of the hinge 5 before and after pack 2 is opened, respectively. The discontinuity line 6 extends linearly across the rear wall 9 of the base 3 of pack 2. The discontinuity line 6 comprises a plurality of spaced weak lines 10 in the material 7 of pack 2. As seen in Figure 2C, when the lid 4 is first rotated to the open position around the hinge 5, the discontinuity line 6 is configured to visibly fold in the spaces 11 between the plurality of weak lines 10, thus forming a continuity line 8.

[0050] In some embodiments, the multiple weak lines 10 are multiple cuts in the material 7 of pack 2. The cuts 10 extend through the entire thickness of the material 7. Alternatively, the cuts 10 may extend only partially through the thickness of the material 7. Weak lines that partially or completely penetrate the thickness of the material may be formed using a laser.

[0051] Providing the pack hinge as an indicator of tampering is preferable because the hinge design can be easily formed during the manufacturing of the pack blank without having to change the overall structure of the blank. Furthermore, the hinge can be formed as a discontinuous line using standard machining and fabrication methods.

[0052] Figures 3A to 3C show another embodiment in which the hinge 5 has a linearly extending discontinuity line 6 comprising a pair of spaced-apart fragile lines 10. As described above, when the lid 4 first rotates to the open position around the hinge 5 to form a continuity line 8, a visible fold is formed in the space 11.

[0053] Alternatively, the discontinuity line 6 extends non-linearly. Embodiments in which the discontinuity line 6 extends non-linearly are shown in Figures 4A to 8C.

[0054] As shown in Figures 4A to 8C, pack 2 has side walls 12 hanging down from each edge of the rear wall 9. Discontinuity line 6 has a pair of fragile lines 10, each having a first linear section 13 in the rear wall 9 that extends linearly toward each other from each side wall 12 of pack 1, and a second section 14 around which the material 7 of pack 2 folds when the lid 4 is opened. The pair of fragile lines 10 are spaced apart from each other. When the lid 4 is first rotated to the open position, the material 7 of pack 2 is configured to be visibly creased such that two visible folds are formed in the space 11 between the pair of fragile lines 10. Each of the visible folds is parallel and spaced apart from each other.

[0055] When the lid 4 is first folded into the open position around the hinge 5, tension is generated along the discontinuity line 6 that defines the hinge 5. The generated tension causes the weak line 10 to break, and the material 7 of pack 2 begins to crease as it bends. The material 7 creases along the minimum resistance line that is formed in the material 7 of pack 2, which will be along the space 11 between the broken weak lines 10.

[0056] As seen in Figures 4A to 7C, the second section 14 of the pair of weak lines 10 is non-linear. In particular, the second section 14 defines an imperfect, substantially elliptical shape in the material 7 of pack 2. When the lid 4 is first rotated to the open position around the hinge 5, the material 7 of pack 2 is configured to visibly fold to form a complete, substantially elliptical shape.

[0057] Alternatively, as seen in Figures 8A to 8C, the second section 14 of the pair of weak lines 10 is straight. In particular, the second section 14 defines an imperfect, substantially quadrilateral shape in the material 7 of pack 2. When the lid 4 is first rotated to the open position around the hinge 5, the material 7 of pack 2 is configured to fold in such a way that it forms a complete, substantially quadrilateral.

[0058] Here again, in some embodiments, the multiple weak lines 10 are multiple cuts in the material 7 of pack 2. The cuts 10 extend through the entire thickness of the material 7. Alternatively, the cuts 10 may extend only partially through the thickness of the material 7. Weak lines that partially or completely penetrate the thickness of the material may be formed using a laser.

[0059] Figure 9A shows a blank 1 of a hinged lid type pack according to another embodiment of the present invention. As shown, the hinge line 5 includes a region 15 demarcated by a weak line 16 of the material 7 of pack 2. When the lid 4 is first rotated to the open position around the hinge line 5, tension is generated along the hinge line 5. The generated tension is applied around the region 15 as the material 7 of pack 2 weakens along the weak line 16. Since the generated tension is greater than the force required to break the weak line 16, the weak line 16 breaks, and the region 15 separates from the pack, resulting in the formation of a window 17 in the material 7 of pack 2. This provides the consumer with a visual indication that pack 2 has been opened previously. The material from which pack 2 is formed can be selected, along with the weak line 16 of the pack material, to ensure that the material 7 breaks along the weak line 16 when pack 2 is opened.
