The fourth panel 508 is folded about 180 degrees with respect to the third panel 506 to face an inner surface of the third panel 506 and thereby form the first stop tab ST1.
[0070] Some of the panels of a hinged-lid inner pack blank 600 of an example embodiment can include side flaps, one or more of which can be adhered to other portions of the pack blank 600 to form a hinged-lid inner pack 30. For example, a pack blank 600 can include a first flap 624 connected to one side of the second panel 604 along a first longitudinal fold line L1, a second flap 626 connected to an opposite side of the second panel 604 along a second longitudinal fold line L2, a third flap 628 connected to one side of the fourth panel 608 along a third longitudinal fold line L3, a fourth flap 630 connected to an opposite side of the fourth panel 608 along a fourth longitudinal fold line L4, a fifth flap 632 connected to an end of the third flap 628 along an eleventh transverse fold line T11, and a sixth flap 634 connected to an end of the fourth flap 630 along a twelfth transverse fold line T12. A pack blank 600 of an example embodiment can further include a seventh flap 636 connected to one side of the fifth panel 610 along a fifth longitudinal fold line L5, an eighth flap 638 connected to an opposite side of the fifth panel 610 along a sixth longitudinal fold line L6, a ninth flap 640 connected to one side of the eighth panel 616 along a seventh longitudinal fold line L7, a tenth flap 642 connected to an opposite side of the eighth panel 616 along an eighth longitudinal fold line L8, an eleventh flap 644 connected to one end of the ninth flap 640 along a thirteenth transverse fold line T13, and a twelfth flap 646 connected to one end of the tenth flap 642 along a fourteenth transverse fold line T14. Fifth and sixth flaps 632, 634 can be separated from first and second flaps 624, 626 and third panel 606 by cut lines CL and eleventh and twelfth flaps 644, 646 can be separated from ninth panel 618 by cut lines CL. The cut lines CL between flaps 632, 634 and flaps 624, 626 can be at a slight angle such as at about 95 to about 98 degrees to longitudinal fold lines L1, L2. If desired, the flaps can have other arrangements such as connecting flaps 632, 634 to flaps 624, 626 or panel 606 with suitable fold lines and cut lines.
[0071] One or more panels or flaps of a hinged-lid blank 600 can include adhesive thereon for adhering to other panels or flaps and forming a hinged-lid inner pack 30 according to an example embodiment. Alternatively, adhesive can be applied to one or more of the panels and/or flaps during assembly of a blank 600 into a hinged-lid inner pack 30. For example, one or more sides of the sixth panel 612, the seventh panel 614, the third flap 628, the fourth flap 630, the fifth flap 632, the sixth flap 634, the seventh flap 636, the eighth flap 638, the eleventh flap 644 and twelfth flap 646 can include a layer of adhesive and/or adhesive can be applied thereto during assembly. Additional and/or different panels and/or flaps may include adhesive in other example embodiments, and/or adhesive can be applied to additional and/or different panels and/or flaps during assembly.
[0072] In an example embodiment of assembling a hinged-lid inner pack 30, the fourth panel 608 is folded about 90 degrees with respect to the third panel 606, fifth and sixth flaps 632, 634 are folded about 90 degrees with respect to the third and fourth flaps 628, 630, and the third and fourth flaps 628, 630 are folded about 90 degrees with respect to the fourth panel 608, wherein flaps 632, 634 lie against an interior surface of the third panel 606 and are adhered thereto. The first panel 602 is folded about 180 degrees to lie against the second panel 604, the second panel 604 can be folded about 90 degrees with respect to the third panel 606 and the first and second side flaps 624, 626 can be folded about 90 degrees to lie against the third and fourth side flaps 628, 630 and are adhered thereto. In certain example embodiments, stop tab ST3 is pushed outward, folded about the horizontal line that defines a bottom portion of ST3, so that it sticks out of the fourth panel 608 (see, for example,
[0073] In an example embodiment of forming a hinged-lid L, eight panel 616 is folded about 180 degrees with respect to seventh panel 614 and adhered thereto (or vice-versa seventh panel 614 is folded 180 degrees with respect to the eighth panel 616 and adhered thereto), and the seventh panel 614 is folded about 90 degrees with respect to the sixth panel 612.
[0074] After the front wall 38a of the lid L is formed, the sixth panel 612 is folded about 90 degrees with respect to the fifth panel 610 so as to lie against the top of a bundle 20 that was placed in the lower section of the hinged-lid inner pack 30. With the fifth panel 610 against a back of the bundle, the seventh flap 636 and the eighth flap 638 are folded about 90 degrees with respect to the fifth panel 610 so as to lie against sides of the bundle 20 (for example,
[0075] To form the remainder of the lid L according to an example embodiment, adhesive can be applied to the undersides of eleventh and twelfth flaps 644, 646 and/or the top of the sixth panel 612, and the eleventh and twelfth flaps 644, 646 are folded about 90 degrees to lie against and adhere to the sixth panel 612 (see, e.g.,
[0076] As mentioned above, the hinged-lid inner pack 30 can include projections P to space the hinged-lid inner pack 30 inward of the front and back walls 41, 42 of the outer shell 40. In an example embodiment, the first longitudinal fold line L1 includes a series of U-shaped cuts UC forming projections P extending outwardly from the front wall 31 of the hinged-lid inner pack 30, the second longitudinal fold line L2 includes a series of U-shaped cuts UC forming projections P extending outwardly from the front wall 31 of the hinged-lid inner pack 30, the third longitudinal fold line L3 includes a series of U-shaped cuts UC forming projections P extending outwardly from the back wall 32 of the hinged-lid inner pack 30, and the fourth longitudinal fold line L4 includes a series of U-shaped cuts UC forming projections P extending outwardly from the back wall 32 of the hinged-lid inner pack 30. In the example shown in
[0077] In an example embodiment, stop tabs ST3 and ST2 can be formed from cuts and fold lines in the panels forming the back wall of the hinged-lid inner pack 30 and the tongue 37. The first stop tab ST1 can comprise a fourth panel 508 of the outer shell blank 500 folded about 180 degrees to form a downwardly extending flap ST1 pivotally connected to an upper end of the back wall 42 of the outer shell 40, the flap ST1 having a free end extending downwardly by a first distance D1 which is less than a second distance D2 between the front wall 41 and back wall 42 of the outer shell 40. The second stop tab ST2 can comprise an upwardly extending flap ST2 connected to the tongue 37 along a transverse fold line PFL2 (in some example embodiments, this fold line is perforated), and the third stop tab ST3 can comprise a second upwardly extending flap ST3 connected to the back wall 32 of the hinged-lid inner pack 30 along a transverse fold line ST3FL.
[0078] In an example embodiment, the flap ST2 has a trapezoidal shape formed by a first cutline CL1 in a central portion of the tongue 37. The first cutline CL1 can include first and second angled sections extending from opposite ends of the transverse fold line PFL2 towards the free end of the tongue 37 and a rectilinear section connecting the first and second angled sections (curved corners may connect the angled sections with the rectilinear section), the rectilinear section parallel to and spaced from the transverse fold line PFL2 by a distance D3 which is less that the distance D1 in some example embodiments. The flap ST2 can be folded about 180 degrees or less with respect to the tongue 37 such that a free end of the flap ST2 faces away from the free end of the tongue 37. The flap ST3 can also have a trapezoidal shape formed by a second cutline CL2 in a central portion of the back wall 32 of the hinged-lid inner pack 30. The second cutline CL2 can include first and second angled sections extending from opposite ends of the transverse fold line ST3FL towards the lid L of the hinged-lid inner pack 30 and a rectilinear section connecting the first and second angled sections (curved corners may connect the angled sections with the rectilinear section), the rectilinear section parallel to and spaced from the transverse fold line ST3FL by a fourth distance D4 which is greater than the third distance D3 in some example embodiments.
[0079] In operating the pack 10 by sliding the hinged-lid inner pack 30 away from the bottom wall 45 of the outer shell 40, the free end of the upwardly extending flap ST3 abuts a bottom end (e.g., said bottom end can include the transverse fold line PLF2) of the first upwardly extending flap ST2 when the lid L is fully open. Such abutment occurs because a gap between the upwardly extending flap ST2 and a portion of the tongue 37 adjacent the upwardly extending flap ST2 forms a catch which engages the free end of the downwardly extending flap ST1 when the hinged-lid inner pack 30 is moved away from the bottom wall 45 of the outer shell 40 and causes the lid L to rotate from a closed position to an open position (as this happens, ST3 moves toward flap ST2, and at a certain point the free end of ST3 abuts the bottom end of ST2 and stops the movement).
[0080] As noted in example embodiments, the hinged-lid inner pack blank 600 can include one or more of the fold lines which include one or more perforations. While this is shown in some figures and/or was mentioned in some example embodiments for some of the fold lines, any one of the fold lines can include one or more perforations, which in some cases may facilitate folding. In other example embodiments, the perforations can be omitted from the fold lines.
[0081] In an example embodiment, a slide-action hinged-lid pack 10, comprises an outer shell 40 and a hinged-lid inner pack 30 configured to hold consumer items. The hinged-lid inner pack 30 can comprise a single blank 600 assembled into a front wall 31, a back wall 32, a right side wall 33, a left side wall 34, a bottom wall 35 and a hinged-lid L pivotally connected to an upper end of the back wall 32 for movement between an open position to a closed position, the hinged-lid L comprising a double layer front wall 38a, a back wall 38b, a double layer right side wall 38c, a double layer left side wall 38d and a double layer top wall 36. The outer shell 40 can comprise a single blank 500 assembled into a front wall 41, a back wall 42, a left side wall 44, a right side wall 43 and a bottom wall 45. In an example embodiment, the outer shell 40 and the hinged-lid inner pack 30 are arranged such that the hinged-lid inner pack can slide from a first position at which a top panel 36 of the hinged-lid L is in the closed position and fits within a rectangular opening at upper ends of the front, back and side walls 41-44 of the outer shell 40 to a second position at which the hinged-lid L is in the open position. The outer shell can include a first stop tab ST1 on an inner side of the back wall 42, the hinged-lid inner pack 30 can include a second stop tab ST2 on a tongue 37 extending from the hinged-lid L, and the hinged-lid inner pack 30 can include a third stop tab ST3 on extending outward of the back wall 32. The second stop tab ST2 can be operable to engage the first stop tab ST1 during movement of the hinged-lid inner pack 30 from the first positon to the second position, and the third stop tab ST3 can be operable to abut the second stop tab ST2 when the hinged-lid L is moved to the open position.
[0082] In an example embodiment, the hinged-lid inner pack can include projections P extending outward of the front and back walls 31, 32 of the hinged-lid inner pack 30 such that the front and back walls 31, 32 of the hinged-lid inner pack 30 are spaced inwardly of the front and back walls 41, 42 of the outer shell 40. The projections P can be formed by a series of spaced-apart U-shaped cuts along fold lines between the front wall 31 and side walls 33, 34 of the hinged-lid inner pack 30 and a series of spaced-apart U-shaped cuts along fold lines between the back wall 32 and the side walls 33, 34 of the hinged-lid inner pack 30.
[0083] In an example embodiment, the consumer items can comprise a bundle 20 of smoking articles, the bundle 20 located in the hinged-lid inner pack 30 such that a free end of the bundle 20 is exposed when the lid L is in an open position, a free end of the bundle 20 is covered by the lid L when the lid L is in a closed position, and the free end of the bundle 20 extends outward from an opening at upper ends of the front, back and side walls 41-44 of the outer shell 40 when the hinged-lid inner pack 30 is in an open position.
[0084] In an example embodiment, the first stop tab ST1 comprises a downwardly extending flap connected to the back wall 42 of the outer shell 40, the second stop tab ST2 comprises an upwardly extending flap connected to the tongue 37, and the third stop tab ST3 comprises an upwardly extending flap connected to the back wall 32 of the hinged-lid inner pack 30.
