AUSTRALIA PATENTS ACT 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT ORIGINAL Name of Applicant/s: British American Tobacco (Investments) Limited Actual Inventor/s: Andrew Jonathan Bray and Adrian Roy Stewart-Cox and Alan Douglas Tearle and Steven Holford Address for Service is: SHELSTON IP 60 Margaret Street Telephone No: (02) 9777 1111 SYDNEY NSW 2000 Facsimile No. (02) 9241 4666 CCN: 3710000352 Attorney Code: SW Invention Title: PACK FOR SMOKING ARTICLES Details of Original Application No. 2003209490 dated 11 Mar 2003 The following statement is a full description of this invention, including the best method of performing it known to me/us: File: 43543AUP01 2 Pack for Smoking Articles The present invention relates to a hinged-lid smoking article pack, in particular, but not exclusively, for cigarettes. 5 Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field. As is well known to those skilled in the art, one of the most commonly used cigarette packs is that usually known as the hinged-lid pack (hereinafter referred to as an "HL pack"). 10 The major components of the HL pack are a base, a lid hingedly connected to the base, and an inner frame. It is usual that the standard HL pack has dimensions such that the front and back walls of the pack are of greater width than the side walls thereof. The inner frame of the HL pack comprises a front wall and side walls and is positioned within the base of the pack such that a portion of the inner frame projects above the 15 base of the pack and is exposed when the HL pack is in an open position. The exposed portion of the inner frame is substantially covered by the front and side walls of the lid portion of the HL pack when the pack is in a closed position. In order that consumers receive as much information as possible regarding the product and the brand of smoking articles they choose, it is advantageous that the surface area 20 available to carry such information is maximised. To date, methods of providing information and advertising have included coupons within or attached to packs. However, the use of coupons involves use of more material than is the case in respect of a standard pack and added complications in pack manufacture. The present invention at least in a preferred form has as an aim of providing a 25 smoking article pack having substantially increased advertising space whilst not substantially increasing the amount of material needed to manufacture the pack, or, indeed, any increase in the amount of material whatsoever. A further object of the present invention at least in a preferred form is, whilst providing for increased advertising space, to provide an HL pack for smoking articles having 30 an outward appearance that is not substantially changed from that of a standard hinged-lid pack. The effect may be readily achieved of an outward appearance which is virtually identical to that of a standard HL pack.

3 According to a first aspect of the invention, there is provided a smoking article hinged lid pack, wherein the ratio of the shortest length of a lid front wall to the shortest length of a base front wall is in the range of 35:65 - 95:5, wherein the pack comprises major front and rear walls and minor side walls, the lid being hinged about the major rear wall, the 5 front wall comprising the lid front wall at an upper portion thereof and the base front wall at a lower portion thereof the surface area of the lid front wall is greater than or equal to the surface area of the base front wall and the lid front wall comprises a folded lower edge. According to a second aspect of the invention, there is provided a smoking article hinged-lid pack wherein an angle (D is less than 300, said angle D being the angle formed 10 between two straight lines defining, or bounding, (D, one of which straight lines represents the plane of the rear of the base portion of said hinged-lid pack and the other straight line is that straight line which passes through or interconnects the hinge line of said hinged-lid pack and the point which represents the upper edge of the front wall of the base portion of said hinged lid pack, wherein the upper edge of the front wall of the base portion and a lower edge of the 15 lid front wall each provide a line which is substantially parallel to a bottom wall of the pack. Preferably, the lower edge of the lid front wall is disposed above the upper edge of the base front wall when the pack is in a closed position. Preferably the ratio of the shortest length of the lid front wall, to the shortest length of the base front wall, that is ratio C:B, is in the range of about 50:50 to about 95:5. 20 Suitably the ratio of the shortest length of the lid front wall to the shortest length of the base front wall perpendicular is in the range of about 50:50 to about 90:10. Preferably the ratio is in the range of about 50:50 to about 75:25 and even more preferably the ratio is in the range of about 50:50 to about 60:40. Preferably the pack further comprises an inner frame within the pack, wherein 25 the lower edge of the lid front wall is spaced from at least a portion of the upper edge of the base front wall to expose a portion of the inner frame, when the pack is in a closed position. It will be readily apparent to those skilled in the art that an increase in ratio C:B may be achieved by, for example, decreasing B alone or, alternatively, by decreasing dimension B 30 and simultaneously increasing dimension C. Preferably an increase in ratio C:B is provided by a reduction in dimension B and a proportional increase in dimension C. It is much by preference that the reduction in dimension B is equal to the increase in dimension C.

3a Preferably, the lengths of the lid front wall and base front wall are measured perpendicular to the bottom wall, and more particularly the bottom front wall fold line. Preferably when the pack is in a closed position, the lower edge of the lid front wall is in abutment with the upper edge of the base front wall. The line of abutment of the lower 5 edge of the lid front wall and the upper edge of the base front wall may be substantially parallel to the bottom wall of the pack. In this embodiment of the present invention the vertical height of the pack, F, is equal to the sum of the lengths of the lid front wall, C, and the base front wall, B, which lengths C and B are measured perpendicular to the bottom wall of the HL pack.

4 Alternatively, when the pack is in a closed position, the lower edge of the lid front wall is in an other than abutting relation with the upper edge of the base front wall. In this further embodiment of the present invention the vertical height of the pack, F, is greater than the sum of the lengths of the lid front wall, C, and the base front wall, B, which lengths B and 5 C are measured perpendicular to the bottom wall of the HL pack. In accordance with a further alternative embodiment of the present invention, when the pack is in a closed position, the lower edge of the lid front wall is in partial abutment with the upper edge of the base front wall. The line of abutment of the lower edge of the lid front wall and the upper edge of the base front wall may be substantially parallel to the bottom wall 10 of the pack. That portion of the lower edge of the lid front wall that is in other than abutting relation with the base front wall may overlap a portion of the base front wall or alternatively may be spaced apart from the base front wall such that a portion of the inner frame is exposed when the pack is in a closed position. 15 The inner frame between the top edge of the base front wall and the upper edge of the inner frame may be printed with indicia and/or graphics only visible to the consumer when the pack is in an open position. Alternatively, or in addition, the inward facing surface of the lid front wall may be printed with indicia and/or graphics only visible to the consumer when the pack is in an open 20 position. Suitably, the preferred ratios mentioned herein may be selected in order to provide the required surface area for graphics and/or indicia. Advantageously, in the closed position, the smoking article pack of the present invention has the appearance of a hinged lid pack for smoking articles. 25 In order that the invention may be easily understood and readily carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which: Figure 1 shows a pack according to a first aspect of the present invention, the pack being in a closed position; 30 Figure 2 shows a pack according to a first aspect of the present invention, the pack being in an open position; Figure 3 shows a pack according to an alternative embodiment of the present invention, the pack being in a closed position; 5 Figure 4 shows a pack blank for the body of a pack according to the invention of Figures I and 2; Figures 5 and 6 show an inner frame used in conjunction with the body of a pack of the present invention; 5 Figure 7 shows a side view of the pack of Figure 3, which pack is shown without an inner frame. Figure 1 shows a smoking article HL pack I in a closed position. The pack I comprises a base 2 and a lid 3, the base having a front wall 4, side walls I I a, bottom wall 10 and back wall 13a. The lid 3 has a top wall 12, a front wall 5, side walls 1 lb and back wall 10 13b. The base back wall 13a and the lid back wall 13b are connected along hinge line 7. Hinge line 7 is parallel to top wall 12 and bottom wall 10. The base front wall 4 and the lid front wall 5 abut one another at a line of abutment 6 when the pack is in the closed position as shown in Figure 1. When the base front wall 4 and the lid front wall 5 abut one another, as is shown in Figure 1, the vertical height of the pack (F) is equal to the sum of the shortest length 15 (C) of lid front wall 5 and the shortest length (B) of the base front wall 4. Figure 1 shows a pack I in accordance with a first aspect of the present invention, the pack 1 having an angle D, which angle (D is formed between two straight lines, one of which straight lines represents the plane of base back wall 13a. The other straight line is that straight line which interconnects the hinge line 7 of the HL pack I and the point which represents the upper edge 20 of base front wall 4. According to one embodiment of the invention, the ratio of the shortest length (C) of the lid front wall 5, perpendicular to the bottom wall 10, to the shortest length (B) of the base front wall 4 perpendicular to the bottom wall 10, is such that there is provided an increased internal surface area for the printing of indicia and/or graphics. The internal surface area may 25 be provided by means of an inner frame, such as that shown in Figures 5 and 6. Alternatively, or in addition, the increased internal surface area may be provided by means of the inward facing surface of the lid front wall 5. Figure 2 shows a smoking article HL pack I according to one embodiment of the present invention in an open position. In Figure 2 the same reference numerals are used as in 30 Figure 1 denoting the same features. In this embodiment, lid back wall 13b and base back wall 13a (not shown) are hinged around hinge line 7 so as to open the pack I and expose inner frame 8. According to one aspect of the invention, the shortest length (A) of the inner frame 8, perpendicular to base bottom wall 10, between the line of abutment 6 and the lowest point 6 of the upper edge of the inner frame 9, is such that the exposed surface of the inner frame 8 may be printed with indicia and/or graphic art. Alternatively, or in addition, the inward facing surface of lid front wall 5 may be printed with indicia and/or graphic art. 5 Figures 3 and 7 show a smoking article HL pack I according to an alternative embodiment of the present invention in a closed position. In Figure 3 the same reference numerals are used as in earlier Figures denoting the same features. In this embodiment the lower edge of lid front wall 5 is spaced apart from base front wall 4 and a portion of the inner frame 8 is exposed when the pack is in a closed position. In the embodiment shown in Figure 10 3 and Figure 7, the vertical height of the pack (F) is greater than the sum of the shortest length (C) of lid front wall 5 and the shortest length (B) of the base front wall 4. In an alternative arrangement, a portion of the lower edge of lid front wall 5 may be spaced apart from base front wall 4 and a portion of the inner frame 8 is exposed when the pack is in the closed position. 15 In a further alternative (not shown) a portion, or all of the lower edge of lid front wall 5 may overlap a portion of the base front wall 4 when the pack is in a closed position. Figure 4 shows a pack blank for the body of a pack I according to the invention of Figures 1 and 2. Like numerals have been assigned to the like parts of Figures 1 and 2. The blank comprises a base front wall 4, a bottom wall 10, base back wall 13a, lid 20 back wall 13b, top wall 12 and lid front wall 5. Base front wall 4 has side margins 14 and side flaps 15 depending therefrom. When the pack is erected, side flaps 15 rest inside side walls 1 Ia and may be glued thereto. Side walls I Ia have bottom margins 16 and base wall inner flaps 17 depending therefrom. When the pack is erected, base wall inner flaps 17 rest inside bottom wall 10 and 25 may be secured thereto. Lid back wall 13b has side margins 18 and side flaps 19. Side flaps 19 have top margins 20 and top wall side flaps 21 depending therefrom. When the pack is erected side flaps 19 rest inside, and are secured to, lid side walls I l b. In addition, top wall side flaps rest inside and may be secured to top wall 12. In Figure 4 fold lines are shown as solid lines and lines of cut are shown as dashed 30 lines. In one embodiment of the present invention, when the pack is erected and in a closed position, the top edge 22 of front base wall 4 and the lower edge 23 of front lid wall 5 abut one another at a line of abutment 6 (not shown).

7 Alternatively, top edge 22 of front base wall 4 and lower edge 23 of front lid wall 5 may be spaced apart when the pack is erected and in a closed position. The surface area of the blank of Figure 4 is not substantially increased over that of a standard hinged lid pack blank (excluding the inner frame). The surface area of a standard 5 hinged lid pack blank (excluding the inner frame) is about 21685mm 2 Figures 5 and 6 show an inner frame 8 to be used in conjunction with the body of a pack 1 of the present invention. The lowest point of the upper edge of the inner frame is shown as 9 in Figures 5 and 6.
