Description:
BACKGROUND OF THE INVENTION 
     This invention relates to folding cartons and blanks therefor, particularly to cigarette packs, and more particularly to a cigarette box having a side-hinged lid. 
     Cigarettes are typically sold in packs of twenty to twenty-five cigarettes. Two types of packs are in general use. The first type is the &#34;soft pack,&#34; which is a bundle of cigarettes wrapped in foil, overwrapped with a paper wrapper which usually has brand and other information printed on its outer side, and overwrapped again with a sealed transparent film overwrap. The second type is the &#34;box&#34; or &#34;FLIP-TOP® box,&#34; which is a hard paperboard box containing a foil-wrapped cigarette bundle and having a hinged lid at the top and a sealed transparent film overwrap. Typically, a paperboard insert surrounds the bundle at least near the top of the box providing a frictional engagement surface to retain the lid in the closed position when desired. A cutout in this insert allows a smoker to remove cigarettes from the box. 
     Each type of pack has its own advantages and disadvantages. The soft pack collapses as cigarettes are removed from it, taking up less space in a smoker&#39;s pocket or purse as the contents are smoked, while providing an approximate external indication of the number of cigarettes remaining in the pack. However, once the transparent film overwrap of a soft pack is opened, it cannot be reclosed. As a result, any loose tobacco in the pack may eventually drop from the pack into the smoker&#39;s pocket or purse. The cigarettes can also be damaged if the pack is roughly handled. For these reasons, many smokers prefer the FLIP-TOP® box, which can be reclosed to prevent loose tobacco from dropping out, and which offers better protection for the cigarettes within it. 
     SUMMARY OF THE INVENTION 
     It is an object of this invention to provide a cigarette pack which will prevent the dropping out of loose tobacco. 
     It is also an object of this invention to provide a cigarette pack of increased attractiveness to smokers. 
     In accordance with the invention, a folding carton is provided which has the appearance and attractiveness of a cigarette case. The carton has a caddy member and a cover member. The caddy member is of a solid rectangular shape and has a height approximately the length of a cigarette, a width approximately an integral multiple of the diameter of a cigarette, and a depth sufficient to accommodate a plurality of rows of cigarettes. The caddy member has front and back walls defined by the height and the width, top and bottom walls defined by the width and the depth, and side walls defined by the height and the depth. The front wall and the top wall each have a cutout portion along their common edge, the cutout portions together forming an opening for the withdrawal of cigarettes. The cover member is attached by a hinge to a side wall of the caddy member and nestingly engages the front, side, top and bottom walls of the caddy member. 
     Preferably, the caddy member and the cover member are erected from separate blanks, but they can also be erected from a single blank. The cover member is also preferably notched to allow the smoker to grasp the caddy member while opening the cover.

     DETAILED DESCRIPTION OF THE INVENTION 
     A preferred embodiment of the cigarette pack of the present invention is shown in FIGS. 1-3. Cigarette pack 10 includes a caddy member 11 and a cover member 12 and, when closed, is similar in size and shape to known cigarette packs. Caddy member 11 differs from known FLIP-TOP® boxes in the absence of the lid, and has a front wall 20, back wall 21, side walls 22, 23, top wall 24, and a bottom wall (not shown). Cutout portions 25 in front wall 20, and 26 in top wall 24, form an opening for the removal of cigarettes from caddy member 11. 
     Cover member 12 has a front wall 30, top and bottom walls 31, 32, and side walls 33, 34 and nestingly engages caddy member 11. Cover member 12 is attached by hinge 35 at the vertical center line of side 23 of caddy member 11. 
     As seen in FIG. 1, cigarette pack 10 resembles an ordinary FLIP-TOP® box in size and shape when cover member 12 is closed. Cover member 12 is retained in the closed position by the frictional engagement of corners 27, 28 of caddy member 11 with the interior of side wall 33 of cover member 12. A triangular notch 13 is provided in cover member 12 to allow caddy member 11 to be grasped for opening cigarette pack 10. 
     When open, as seen in FIG. 2, cigarette pack 10 resembles a cigarette case, increasing its attractiveness to smokers. At the same time, when closed, cigarette pack 10 is effective in preventing the dropping out of loose tobacco into a smoker&#39;s pocket or purse. 
     A paperboard blank 40 from which caddy member 11 is erected is shown in FIG. 4. Blank 40 has a front wall panel 41 defined by parallel long front-defining score lines 601, 602, short front-defining score line 603, and front cutout portion 701.

     In an alternate embodiment 60 shown in FIG. 6, cover member 61 is hinged to caddy member 11 at corner 62. Cigarette pack 60 can be formed from two separate members as is cigarette pack 10. For example, blank 50 can be modified by eliminating score line 621 and cuts 808 and 809, changing score lines 620 and 622 to cuts, and changing cuts 805 and 806 to score lines, and then adhering the entire hinge panel 560 to side 23 of caddy member 11, with score line 613 functioning as hinge 62. 
     Cigarette pack 60 can also be formed from a single blank such as that shown in FIG. 7, in which all score lines are marked 600, all cutouts are marked 700, and all cuts are marked 800. 
     The cigarette pack described herein provides a closed container which prevents the dropping out of loose tobacco. It is also attractive to smokers as it simulates a cigarette case. The exterior of the pack can be printed with brand and other information and with decorative material in the same manner as other cigarette packs. Similarly, the cigarettes contained within the pack can be wrapped in foil in the manner known to those in art, and the pack can be conventionally overwrapped with a transparent film overwrap to keep the cigarettes fresh. 
     It will be apparent to those skilled in the art that the invention described herein can be practiced by other than the embodiments described above, which are presented for the purpose of illustration and not of limitation, and the present invention is limited only by the claims which follow.
