Definitions

  • the present invention relates to a pack for articles such as cigars, cigarillos and cigarettes.
  • the invention also relates to a blank for forming the pack, and a method and apparatus of making the pack.
  • a prismatic pack that is of triangular cross-section is known from WO 01/44077.
  • the pack is formed of a rectangular blank divided by crease lines into four panels, three of which form the sides of the pack and the fourth is a connector which connects the outer two of the three panels.
  • the blank has, attached to opposite top and bottom edges of one panel, triangular panels which define the cross-sectional shape of the pack.
  • two connecting flaps are connected to respective edges of each triangular panel. The flaps connect the triangular panel to the sides of the erected pack.
  • One embodiment of the invention provides a blank for forming a prismatic pack of triangular cross-section.
  • the blank has a generally rectangular portion which is divisible into three body panels for forming the sides of the triangular cross-section.
  • a top triangular panel is connected to the top edge of one of the body panels and a bottom triangular panel is connected to the bottom edge of one of the body panels.
  • the top and bottom triangular panels correspond to the triangular cross-section of the pack.
  • First and second top flaps are connected to the top edge of respective body panels, other than the body panel to which the top triangular panel is connected. Each of the first and second top flaps extends along substantially the whole width of its respective body panel.
  • the first top flap is substantially similar in size and shape to the top triangular panel.
  • First and second bottom flaps are connected to the bottom edge of respective body panels, other than the body panel to which the bottom triangular panel is connected.
  • Each of the first and second bottom flaps extends along substantially the whole width of its respective body panel.
  • the first bottom flap is substantially similar in size and shape to the bottom triangular panel.
  • the resulting triangular pack has triangular ends which, when viewed from the sides, have complete fold lines extending along the whole length of the straight portion of each side. Any gaps which may appear at the vertices of the triangular ends are minimised, thus improving the appearance and closure of the pack.
  • the use of a triangular panel and triangular flaps of substantially equal size and shape stiffens the ends to improve rigidity of the pack.
  • the form of the blank in having end panels and flaps extending only from the edges of the body panels, and no further flaps extending from the end panels or from the flaps themselves, simplifies erection of the pack, especially in respect of an automated folding procedure.
  • the first top flap is slightly smaller than the top triangular panel and the first bottom flap is slightly smaller than the bottom triangular panel. This helps the top and bottom flaps to fold under the top and bottom triangular panels, respectively.
  • the second top flap is connected to the body panel which is between the body panels connected to the top triangular end panel and the first top flap.
  • the second bottom flap is connected to the body panel which is between the body panels connected to the bottom triangular end panel and the first bottom flap. This helps to avoid interference when folding between the first top flap and the top triangular end panel, and likewise between the first bottom flap and the bottom triangular end panel.
  • Another embodiment of the invention provides a blank for forming a prismatic pack of triangular cross section.
  • the blank has a generally rectangular portion which is divisible into a middle panel and two outer side panels; a top triangular panel and a bottom triangular panel connected to top and bottom edges of the rectangular portion; and a plurality of flaps for connecting the triangular panels to the side panels in the erected pack.
  • One of the triangular panels has at least one free edge and the other panel has a flap attached to at least one edge.
  • Another embodiment of the invention provides a blank for forming a prismatic pack of triangular cross-section.
  • the blank has a generally rectangular portion which is divisible into a middle panel and two outer side panels; a top triangular panel connected to the top edge of one of said side panels and a top flap connected to the top edge of another of the side panels; a bottom triangular panel connected to the bottom edge of one of said side panels and a bottom flap connected to the bottom edge of another of the side panels; the top and bottom triangular panels defining in the erected pack said triangular cross-section of the pack; a further flap connected to the top edge of the side or middle panel which has no top triangular panel or top flap connected thereto, the further flap being of length along the top edge substantially equal to the width of the side or middle panel to which it is connected; and a further flap connected to the bottom edge of the side or middle panel which has no bottom triangular panel or bottom flap connected thereto, the flap being of length along the bottom edge substantially equal to the width of the side or middle
  • Another embodiment of the invention provides a prismatic pack of triangular cross-section having three body panels for forming the sides of the triangular cross-section.
  • a top triangular panel is connected to the top edge of one of the body panels and a bottom triangular panel is connected to the bottom edge of one of the body panels.
  • the top and bottom triangular panels correspond to the triangular cross-section of the pack.
  • First and second top flaps are connected to the top edge of respective body panels, other than the body panel to which the top triangular panel is connected.
  • Each of the first and second top flaps extends along substantially the whole width of its respective body panel.
  • the first top flap is substantially similar in size and shape to the top triangular panel.
  • First and second bottom flaps are connected to the bottom edge of respective body panels, other than the body panel to which the bottom triangular panel is connected.

  • an apparatus for making a pack of prismatic form which pack has a substantially triangular cross-section.
  • the apparatus comprises at least one arbour of substantially triangular form, blank application means for applying a blank to the arbour, and rotational drive means operable to rotate the arbour to effect folding the blank to form a prismatic pack of substantially triangular cross-section.
  • a method of making a pack of prismatic form and having a substantially triangular cross-section comprises applying a blank to an arbour of triangular cross-section; rotating the arbour to effect folding of the blank into a hollow prismatic form of triangular cross-section having one closed end and one open end; inserting a product or bundle of product shaped to be received in the pack; and closing the open end to provide a pack of prismatic form of substantially triangular cross-section and closed at both ends.
  • a bundle of product is used as a support for folding the blank instead of an arbour.
  • the product bundle may first be enclosed completely within a foil wrapper to hold the product in place, prior to using the bundle as a support for folding the blank.

  • FIG. 2 shows a blank 10 in accordance with one embodiment of the invention.
  • Blank 10 may be of card or any other suitable material.
  • Blank 10 comprises a generally rectangular section divided by three pairs of crease zones 342, 342'; 341, 341'; and 343, 343', and with top and bottom edges 30, 31.
  • the top and bottom edges 30 and 31 may represent pre- weakened fold lines for end panels and flaps, as described in more detail below.
  • the first crease zone of each pair forms an edge of the container portion 6 of the erected pack 20 and the latter crease zone of each pair forms a corresponding edge of the lid portion 8 of the erected pack 20.
  • the crease zones 342, 342'; 341, 341'; and 343, 343' extend from the top edge 31 to the bottom edge 30 of the blank and lie parallel to the side edges 381 and 382 of the blank 10.
  • the crease zones 342, 342'; 341, 341 '; and 343, 343' correspond to the rounded edges of the pack 20 shown in Figure 1 and divide the blank 10 into the body panels 11+15, 12+16, and 13+17, which form the sides of the erected pack 20.
  • the body panels are joined to one another along their longitudinal margins.
  • Connecting panels 14, 18 extend from the edge 343, 343' and are arranged to overlap with and adhere to panels 13 and 17 (e.g. using glue) to fix the form of the erected pack 20.
  • a cut defines a demarcation line 19 between the lid portion 8 and the container portion 6.
  • the demarcation line 19 extends across the blank 10 to define the panels 11 and 12 of the container portion 6 of the erected pack from panels 15 and 16 of the lid portion 8 of the erected pack.
  • the demarcation line separates crease zone 342 from crease zone 342', crease zone 341 from crease zone 341', and crease zone 343 from crease zone 343 '.
  • a crease line 28 dividing the connecting panels 14 and 18 is aligned with a corresponding crease line 27 dividing the side panels 13 and 17 to provide a hinge for the lid portion 8.
  • the crease lines 28 and 27 are linked to opposite ends of the demarcation line 19.
  • top and bottom triangular panels 21 and 25 are connected to the panels 17 and 13 respectively and hence lie at opposite ends of one face (body panel) of the erected pack.
  • the top and bottom triangular panels 21 and 25 form the exterior end panels in the erected pack 20, perpendicular to the body panels (see Figure 1), and hence have a size and shape that corresponds generally to the triangular cross-section of erected pack 20.
  • neither triangular panel 21 nor triangular panel 25 has any flaps on the edges thereof. These edges can therefore be considered as free, in that they have no appendages.
  • panel 13 forms the back of the pack, in that it includes the hinge line 17 for the lid.
  • the material of the blank is continuous through body panel 13, the hinged lid panel 17, and the triangular top end panel 21, for improved strength and closure.
  • Triangular flaps 121 and 125 therefore lie at opposite ends of one face (body panel) of the erected pack.
  • the triangular flaps 121 and 125 are of the same shape as, but slightly smaller than, the triangular panels 21, 25.
  • the middle panel 12 has a substantially rectangular flap 26 attached along bottom edge 30 and the middle panel 16 has a corresponding rectangular flap 22 attached along the top edge 31.
  • Each of the rectangular flaps 22, 26 extends along edge 31, 30 respectively a distance substantially equal to the distance between crease zones 341' and 342'. This distance is also substantially equal to the length of the junction of the triangular panels 21 and 25 with corresponding side panels 17 and 13 respectively.
  • the triangular end panels 21 and 25 of the blank 10 may be offset, i.e. each triangular end panel 21 and 25 may be attached to a different rectangular panel.
  • the triangular end panel 21 may extend from the top edge 31 of side panel 17, while the triangular end panel 25 may extend from the bottom edge 30 of the middle panel 12 (as for the embodiment of Figure 3A, as shown below).
  • the end flaps 22, 121, 26 and 125 are then also offset in corresponding fashion.
  • triangular flaps 121, 125 may be provided on middle panels 12, 16, with the rectangular flaps 22, 26 provided on side panels 11, 15. However, such an arrangement may increase the risk of interference between triangular end panel 21 and triangular end flap 121, likewise for panel 25 and flap 125.
  • flaps 22 and 26 can be sized to avoid any such interference.
  • flaps 22 and 26 may have a shape other than rectangular.
  • flaps 22 and 26 may comprise truncated versions of triangular flaps 121, 125 (this would be more trapezoidal in shape, but with rounded sides to match the rounded edges of pack 20).
  • FIG. 1 An example of how a pack may be erected using the blank of Figure 2 is as follows: a. Fold the panels 11, 15; 12, 16 and 13, 17 and the connecting panels 14, 18 relative to each other about the crease zones 342, 342'; 341, 341'; and 343, 343' into a triangular form having a cross-section the same size and shape as the triangular end panels 21 and 25; b. Overlap the connecting panels 14, 18 inside the side panels 13, 17 and stick together to fix the triangular form; c. Fold rectangular flaps 22 and 26 to be at right angles to their adjoining rectangular panels 16 and 12; d.
  • the triangular flaps 121, 125 are glued to rectangular flaps 22 and 26, and the triangular panels 21 and 25 are glued to the triangular flaps 121 and 125 at a suitable time (or times) in the process.
  • the resulting triangular pack 20 has triangular ends that, when viewed from the sides, have complete fold lines extending along the whole length of the straight portion of each side.
  • the triangular flaps 121 and 125 (and also the triangular panels 21 and 25) extend into the vertices of the triangular cross-section leaving substantially no gaps at the edges thereof and provide folded edges extending across substantially the whole width of each side panel.
  • the provision of a triangular flap 121, 125 inside the corresponding triangular end panel 21, 25, where the triangular flap is of substantially the same size and shape as the end panel provides extra strengthening and rigidity. For example, it helps to avoid any tendency for creasing of the top surface of the lid, which is stiffened by the presence of both triangular flap 121 and triangular end panel 21 of substantially the same size and shape.
  • all three panels 17, 16, and 15 are provided with a panel or flap extending along substantially the whole top edge 31 of the relevant panel.
  • panel 17 is provided with flap 21
  • panel 16 is provided with flap 22
  • panel 15 is provided with flap 121.
  • This configuration helps to avoid any gap forming between the end panel of the erected pack (i.e. panel 21) and the side faces of the pack. This improves the appearance of the pack, as well as helping with sealing of the pack to prevent unwanted ingress or egress (such as loss of moisture from tobacco contained within the pack).
  • a similar arrangement without any gaps is also formed at the bottom of the pack by end panel 25, rectangular flap 26, and triangular flap 125.
  • the erected pack has rounded edges between the main panels 11, 12, and 13.
  • the edges of the erected pack may have any other suitable shape, for example, sharp or chamfered, in which case the form of the creased zones 341, 342, 343, and 341', 342' and 343' can be modified suitably to provide such edges.
  • the shape of the corners/edges provided on the end panels and flaps is also suitably modified to have a corresponding shape.
  • the panels and flaps can be arranged such that there are substantially no gaps at the vertices, and folded edges extend across substantially the whole width of each side panel.
  • a carousel 60 includes a series of twelve arbours 62 that are circumferentially spaced around the carousel 60 and each arbour 62 extends in a direction parallel to the rotational axis of the carousel to provide 12 assembly stations Sl -S 12 at which various assembly processes are progressively completed. (It will be appreciated that the number of arbours in carousel 60 may vary according to the number of stations involved in the assembly process and the rate of packs to be produced). The cross-sectional shape of the arbours matches the triangular cross-section of the pack 20.
  • the carousel 60 is rotated clockwise upon a fixed axis allowing the relevant arbour to rotate to the next station Sl-S 12.
  • the progression of the relevant arbour 62 sequentially incorporates the assembly of a foil wrapper 50 (Sl) (to maintain product quality), the assembly of an inner frame 40 (S3) (when a separate inner frame is used), the assembly of a diecut blank 10 (S4), the insertion of a bundle of product 52 (SlO), and subsequent exit of a partially assembled pack from the arbour (Sl 1, S 12) to receive the final closure of the open end of the pack (not illustrated).
  • Plough folding uses the rotational force of the arbour carousel to create a fold when a stationary object, plough folding objects or folding edges are in the rotational path of the unfolded panels of the blank rotating with the arbour.
  • force folding uses a variety of moving apparatus in motion relative to the arbour and applying force to the panel to create the fold.
  • the bare arbour 62 which is substantially triangular in shape, receives a pre- cut foil wrapper 50 from a foil embossing and cutting device 70.
