  • the pack further comprises a lid configured to open and close the access opening and which extends over the protruding part of the support structure when the lid is closed.
  • an inner frame for a pack comprising a front panel and a side panel, wherein the front and/or side panels comprise multiple layers.
  • the front and side panels may be formed from a single sheet of material.
  • the sheet of material includes fold lines to enable the sheet to be folded about said fold lines to form said multiple layers.
  • the inner frame comprises a side panel and a side reinforcement panel, the side reinforcement panel being positionable so that it overlaps its
  • the side panel may join the front panel at a first fold line and the side reinforcement panel may join the side panel at a second fold line.
  • the first and second fold lines are parallel.
  • the first and second fold lines may extend at an angle relative to each other.
  • the front panel may comprise a front reinforcement panel that joins the front panel at a front panel fold line, the front reinforcement panel being foldable about said front panel fold line so that it overlaps the front panel to form a multi-layered front wall.
  • the front panel comprises a front reinforcement panel that joins the front panel at a front panel fold line and side reinforcement panels that extend from the front reinforcement panel and are joined thereto by a second fold line, the front reinforcement panel being folded about the front panel fold line so that the front reinforcement panel overlaps the front panel and the side reinforcement panels overlap corresponding side wall panels to form multi-layered front and side walls.
  • the side panel may have a major surface that overlaps a major surface of the side reinforcement panel.
  • the major surface of the side reinforcement panel can be held against the major surface of the side panel by adhesive.
  • the invention also provides a blank for forming an inner frame according to the invention, for a pack.
  • the invention also provides a method of forming an inner frame comprising the steps of providing a blank comprising a front panel, a side panel and a side reinforcement panel, and positioning the side reinforcement panel so that it overlaps the side panel.
  • the invention also provides an inner frame for a tobacco industry pack, comprising a front panel and a side panel, wherein the front and/or side panels comprise multiple layers.

  • the side panels 24,25 of the inner frame 12 further comprise side reinforcement panels 26, 27 that each meet a corresponding side panel 24, 25 at a second fold line 18, 19 which extends in a direction parallel to the first fold line 16, 17.
  • the side reinforcement panels 26, 27 are folded at the second fold line 18, 19 so that a major surface of each side reinforcement panel 26, 27 abuts against a major surface of a corresponding side panel 24, 25 to form a double layer.
  • the side reinforcement panels 26, 27 are preferably folded about respective second fold line 18, 19 in the direction down into the page when viewing Figure 2 so that they lie against an inner surface of the side panels 24, 25, i.e. the surface of each of the side panels 24, 25 which is not visible in Figure 2.
  • the side reinforement panels 24,25 may alternatively be folded about respective second fold line 18, 19 in an opposite direction, so that they lie across a front face of the side panels 24, 25, i.e. the face of each of the side panels 24, 25 which are visible in Figure 2.
  • the side reinforcement panels 26, 27 may be held against the side panels 24, 25 using an adhesive. The use of adhesive may further increase the robustness and rigidity of the inner frame.
  • each side reinforcement panel 26, 27 may overlap the whole surface area of a corresponding side panel 24, 25, i.e. each side reinforcement panel 26, 27 may be the same size and shape as a corresponding side panel 24,25.
  • each side reinforcement panel 26, 27 may be of a different size or shape to its corresponding side panel 24,25 and so may only overlap a portion of a major surface of corresponding side panels 24, 25.
  • the inner frame 12 may include tabs 20 that extend from the side walls 14, 15 to engage the side wall lid panels 6b, 7b when the lid 3 is in the closed position to increase the friction between the lid 3 and the inner frame 12, although these are optional.
  • the increased friction provided by the tabs 20 increases the resistance to the opening of the lid 3, enabling the lid 3 to better stay in the closed position. It will be appreciated that, in another embodiment one or more further side
  • reinforcement panels may extend from the side reinforcement panels 26, 27 and be separated from the side reinforcement panels 26, 27 by a fold-line.
  • the side panels 24,25, the side reinforcement panels 26, 27 and any additional side reinforcement panels provide a multi-layered structure to the inner frame , i.e a side wall having more than two layers.
  • a blank 31 for an inner frame 12 of a second embodiment of the invention is shown in Figure 3 and is identical to the first embodiment, with like features retaining the same reference numerals, except that each second fold line 18, 19 extends in a direction perpendicular to the first fold lines 16, 17.
  • the side reinforcement panels 26, 27 are folded in the direction down into the page when viewing figure 3, although they could also be folded in the opposite direction.
  • additional side reinforcement panels may extend from the side reinforcement panels 26,27 to enable a multi-layered structure to be formed. Furthermore, a combination of the embodiments shown in Figures 2 and 3 is envisaged in which there is a side reinforcement panel 26,
  • the second fold lines 18, 19 are described as extending in a direction perpendicular or parallel to the first fold lines 16, 17, the second fold lines 18, 19 may alternatively extend at some other angle to the first fold lines 16, 17.
  • a blank 41 for an inner fame 12 of a third embodiment of the invention is shown in Figure 4.
  • the blank 41 comprises a front panel 23 that meets side panels 24, 25 at first fold lines 42, 43.
