Definitions

• the invention relates to packaging for smoking articles, such as cigarettes.
• the invention relates to packaging smoking articles in a shell and slider type pack.
• Cigarette packs having an outer shell and inner slider are well-known, see for example: German patent DE 29619233, PCT patent application WO 00/45654, US patent US 3096878, US patent US 3107008, US patent US 3828923, GB Patent GB 335838 and Swiss patent CH 370699.
• the contents of the inner slider usually cigarettes, are accessed by pulling the inner slider from the outer shell to expose the contents of the inner slider.
• Some of these existing packs also include some form of mechanism to prevent the inner slider from being completely removed from the outer shell.
• a pack for smoking articles comprises an outer shell.
• the outer shell comprises opposing front and back major panels, two opposing minor side panels and opposing first and second ends. The first end is open and the second end is closed.
• the pack further comprises an inner tray formed with an aperture.
• the inner tray is located within the outer shell and is slidable along a length axis directed between the first and second ends of the outer shell so as to emerge from the first open end of the outer shell.
• the pack further comprises a tongue having a head portion located inside the inner tray and wider than said aperture, and a stem portion connected at one end to the outer shell at or near the second end of the outer shell. The stem portion extends through the aperture to join the head portion.
• the aperture and tongue provide a stop mechanism to prevent withdrawal of the inner tray from the first end of the outer shell past a predetermined limit.
• the tongue is substantially T-shaped (other embodiments may involve a mushroom shape, etc).
• the stem portion comprises an end region which is folded parallel with and adhered to the second end of the outer shell.
• the aperture is located centrally between the opposing minor side panels of the outer shell, and extends from a bottom edge of the base of the inner tray, which is adjacent to the second end of the outer shell when the pack is closed.
• the outer shell includes a recessed portion that extends from the open first end of the outer shell partway down the back major panel.
• the recessed portion on the outer shell extends across the width of the back major panel and onto the opposing minor side panels.
• Such a configuration for the outer shell exposes a portion of the inner tray. Accordingly, a user can grip the inner tray for withdrawal from the outer shell in order to access the contents of the pack (e.g. smoking articles such as cigarettes).
• the pack is relatively thin (measuring depth from front to back) compared to a conventional hinged-lid pack. Note that the combination of outer shell and inner tray for such a thin pack is helpful, since in contrast, a very thin conventional hinged-lid pack may have interference problems with the lid opening action.
• Another embodiment of the invention provides a set of blanks for forming such a pack.

• Figure 1 shows a perspective view of a slider and shell pack or packet 1 in accordance with an embodiment of the invention.
• the pack 1 includes an outer shell 3, as shown separately in Figures 2a and 2b, and an inner tray 5, as shown separately in Figures 3a and 3b.
• Smoking articles such as cigarettes may be located in the inner tray 5.
• Figure 2a shows a rear perspective view of the outer shell 3 with the inner tray 5 removed.
• Figure 2b shows a front perspective view of the outer shell 3 with the inner tray removed.
• Figure 3a shows a perspective view of the inner tray 5, viewed from the front.
• Figure 3b shows a perspective view of the inner tray 5, viewed from the rear.
• the outer container 3 has a generally rectangular shape and includes a front major panel 2, a rear major panel 4 and two opposing minor side panels 6, 8.
• the outer shell 3 further includes a bottom end panel 10.
• the top end of the outer shell 3 (opposite the bottom end panel 10) is open to allow the inner tray 5 to be withdrawn from the outer shell 3.
• a recessed portion 12 in the outer shell 3 extends from the open end of the outer shell 3 partway down the rear major panel 4.
• the recessed portion 12 extends around the side edges of the rear major panel 4 onto each of the two minor side panels 6, 8.
• the recessed portion 12 exposes a portion of the inner tray 5 (as shown in Figure 1), thereby allowing a consumer to grasp and pull the inner tray 5 out of the open end of the outer shell 3.
• the recessed portion 12 occupies approximately one third (lengthwise) of the rear major panel 4, from the top of the panel (at the open end) downwards towards bottom end panel 10.
• the recessed portion further extends approximately two-thirds (widthwise) of each of the minor side panels 6, 8, i.e. from rear major panel 4 towards the front major panel 2. It will be appreciated that other embodiments may have other shapes and/or dimensions for the recessed portion 12 on the outer shell 3.
• the inner tray 5 has a substantially rectangular shape and comprises a base panel 7, two opposing side panels 9, 11, and two opposing end panels, namely top end panel 13 and bottom end panel 15.
• An extension panel 17 extends from the bottom end of each side panel 9, 11, and is folded to join the respective side panel to bottom end panel 15.
• the base 7 of the slider 5 is parallel and adjacent to the rear major panel 4 of the outer shell 3; the side walls 9 and 11 of the slider are parallel and adjacent to the side panels 8 and 6 respectively of the outer shell 3; and the bottom end panel 15 of the slider is parallel and adjacent to the bottom end panel 10 of the outer shell. Furthermore, in the position shown in Figure 1 , the top end panel 13 of the inner slider acts to close the pack 1 to prevent the contents from falling out.
• an aperture 19 is included in the base panel 7 of the inner slider 3.
• the aperture 19 extends into the base panel 7 from the edge defined by the bottom end panel 15 and the base panel 7.
• the aperture 19 extends part-way up the base panel 7 (approximately one third lengthwise) towards the top end panel 13.
• the aperture 19 is substantially centrally positioned widthwise on the base panel 7, and occupies approximately two-thirds of the width of the base panel 7 (between opposing side walls 9 and 11).
• the aperture 19 acts in conjunction with a tongue portion (as discussed below) as a stop mechanism to prevent the inner tray 5 from being fully withdrawn from the outer shell 3 when opening the pack 1.
• the top end panel 13 includes a notch 20.
• notch 20 provides the consumer with an additional facility (in particular a gap between end panel 13 of the inner slider 5 and front major panel 2 of the outer shell 3) for holding and pulling the inner tray 5 out through the open end of the outer shell 3.
• a consumer can open the pack 1 by withdrawing the inner tray 5 from the outer shell 3. This withdrawal can be accomplished by pulling on the top panel 13 via the recess 20 and/or by grasping the exposed area on the base 7 and side panels 9, 11 of the inner tray 5.
• the consumer applies pressure to the outer face of the top end panel 13 of the inner tray 5 to push the inner tray 5 back into the outer shell 3.
• the closed position is reached when the bottom wall 15 of the inner slider 5 abuts against the bottom end panel 10 of the outer shell 3 (thereby preventing further movement in this direction).
• Figures 4a and 4b are rear and front views respectively of the pack 1 with the inner tray 5 partly withdrawn from the outer shell 3.
• the pack includes a stop mechanism to limit the withdrawal of the inner tray 5 from the outer shell 3 to the amount shown in Figures 4a and 4b.
• the inner tray In the illustrated position, the inner tray is about 40% withdrawn - i.e. the inner tray 5 has moved a distance corresponding to approximately 40% of the length of the inner tray from the closed position shown in Figure 1.
• FIGs 5a and 5b show schematic front views of the assembled pack 1.
• the outer shell 3 is shown in broken lines (and in transparent form) to illustrate the stop mechanism used to control movement of the inner slider 5 out of the outer shell 3.
• the pack 1 is closed (as in Figure 1), while in Figure 5b, the pack is open (as in Figures 4a and 4b).
• the stop mechanism used to limit movement of the inner slider 5 out from the outer shell utilises interaction between a tongue 21 and the aperture 19.
• a tongue 21 for clarity, those portions of the tongue 21 that are hidden behind the side wall 9 or bottom end panel 15 are shown in broken lines in Figures 5a and 5b (in order to depict the full shape of tongue 21).
• the tongue 21 may be substantially T-shaped and comprises a head portion 24 and a stem portion 23.
• the stem portion 23 is attached at one (bottom) end to the outer shell 3.
• this bottom end of the stem portion is attached to the edge formed by the junction of rear major panel 4 and bottom end panel 10 of the outer shell 3.
• stem portion 23 includes an end region 25 shown in Figure 6c (opposite head portion 24), which is folded parallel to (and adhered to) the bottom end panel 10 of the outer shell 3.
• the opposite (top) end of the stem portion 23 is attached to the (transverse) head portion 24.
• the stem portion 23 is narrower than the head portion 24 (width being defined along the direction between opposing side panels 6 and 8).
• the stem portion 23 of the tongue 21 passes through the aperture 19 such that the head portion 24 is located within the tray of the inner shell — i.e. between the base 7 of the inner slider shell and the front major panel 2 of the outer shell 3.
• the bottom end region of the stem portion is located outside the tray of the inner shell - i.e. between bottom wall 15 of the inner shell and bottom end panel 10 of the outer shell 3 (as mentioned above, the stem portion 23 is attached to the latter).
• the aperture 19 is dimensioned so that it is (slightly) wider than the stem portion 23, but narrower than the head portion 24. This arrangement allows the inner tray 5 to slide unimpeded in the direction from the closed end 10 to the open end of the outer shell 3 in order to open the pack. As this opening occurs, aperture 19 moves along stem portion 23 (i.e. stem portion 23 moves through aperture 19). However, when the position shown in Figure 5b is reached, the inner tray 5 is prevented from being withdrawn any further from the outer shell 3. In particular, in this position, the bottom edge of the aperture 19 (i.e. the edge formed by bottom end panel 15) reaches and abuts against the bottom edge of the head portion 24. Since the head portion 24 is wider than the stem portion 23, and also wider than aperture 19, further movement of the inner slider 5 out from the outer shell 3 is prevented.
• the top edge of the aperture 19 acts as a stop mechanism
• the top edge of the aperture i.e. the edge closest to the top end panel 13
• the shape and position of this edge is relatively flexible.
• this top edge might be moved much closer to the bottom edge (so that aperture 19 becomes a relatively narrow strip or slit).
• the skilled person will be aware of various other possible alternative shapes and dimensions for the tongue 21 and the aperture 19 to form the stop mechanism. Such variations can be used (inter alia) to control the maximum permitted amount of withdrawal of the inner tray from the outer shell.
• Other tongue and aperture shapes can be used.
• the tongue may be L-shaped with the head portion extending transversely of the stem portion on one side only.
• the tongue may alternatively have a head portion in the shape of an arrowhead, a semicircle or an ellipse. Also, the tongue may include two generally parallel, spaced stem portions received in respective apertures in the inner tray, with the head portion of the tongue bridging the stem portions.
• Figure 6a shows a blank 50 suitable for making the inner tray 5 as illustrated in Figures 1, 2a, 2b, 4a, 4b, 5a and 5b in accordance with one embodiment of the invention.
• the blank 50 includes a first panel 51 which is joined by a scored fold line FlO at its bottom edge to a second panel 52.
• the first panel 51 folds against second panel 52 to form end panel 13.
• a hole 502 is provided across the scored fold line FlO and extends onto both the first and second panels 51, 52.
• the first panel 51 is folded back against the second panel 52 along fold line FlO, with the result that the hole 502 defines the notch 20 in the top panel 13 of the inner frame 5. Folding the first and second panels together provides a rounded, stronger edge for top end panel 13
• the second panel 52 is joined by a scored fold line Fl 1 to a third panel 53 that defines the base panel 7 of the inner tray 5.
• the third panel 53 is joined by a scored fold line F12 to a fourth panel 54 that defines the bottom end panel 15 of the inner tray 5.
• a hole or aperture 19 as previously described is cut through the third panel 53.
• the fold lines FlO, FIl and Fl 2 are parallel to each other.
• the third panel 53 is joined by a scored fold line Fl 3 to a fifth panel 55 and by a scored fold line F14 to a sixth panel 56.
• the fold line F14 is parallel to fold line Fl 5.
• the fifth panel 55 and the sixth panel 56 define the opposing side panels 9, 11 respectively of the inner tray 5.
• a seventh panel 57 and an eighth panel 58 are joined by scored fold lines Fl 5 and Fl 6 to the fifth and sixth panels 55, 56 respectively.
• Each of the seventh and eighth panels 57, 58 overlaps with the inside of the second panel 54 (bottom end panel 15 of the inner tray 5), thereby attaching the side panels 9, 11 of the inner tray 5 to the bottom end panel 15 of the inner tray 5.
• a ninth panel 59 and a tenth panel 60 are joined by scored fold lines Fl 7, Fl 8 to the fifth and sixth panels 55, 56 respectively.
• Each of the ninth and tenth panels 59, 60 is each sandwiched between the first and second panels 51, 52 (when folded together) to link the side panels 9, 11 to the top end panel 13 of the inner tray 5.

• the second panel 32 is joined by a scored fold line F2 to a third panel 33 that forms the front major panel 2 on the outer shell 3.
• the third panel 33 is joined at its bottom edge by a scored fold line F3 to a fourth panel 34 that defines a reinforcement panel at the open end of the outer shell 3 (during assembly, the fourth panel is folded back onto the third panel to provide a rounded and strengthened edge).
• the fold lines Fl, F2 and F3 are parallel to each other.
• the first panel 31 is joined by a scored fold line F4 to a fifth panel 35 and by a scored fold line F5 to a sixth panel 36.
• the fold line F4 is parallel to fold line F5, and the fifth panel 35 and sixth panel 36 define opposing side panels 8 and 6 respectively of the outer shell 3.
• a seventh panel 37 and an eighth panel 38 are joined by scored fold lines F6 and F7 to the fifth and sixth panels 35, 36 respectively.
• each of the seventh and eight panels 37, 38 overlaps with the inside of the second panel 32 (bottom panel 10 of the outer shell 3) to attach the side panels 6, 8 of the outer shell 3 to the bottom panel 10 (closed end) of the outer shell 3.
• a ninth panel 39 and a tenth panel 40 are respectively joined by scored regions
• each of scored regions Sl and S2 defines a rounded edge on the front edge of the outer shell 3.
