Description: Description A rigid wrapper for a plurality of packets of cigarettes Technical Field The present invention relates to a rigid wrapper for a plurality of packets of cigarettes. Background Art It is the conventional practice for packets of cigarettes to be packaged in multiples using rigid wrappers commonly known as cartons, which appear substantially parallelepiped in shape. One type of carton consists in a wrapper of flat and elongated shape exhibiting four longitudinal faces, including two main faces and two narrower faces, and two transverse end faces. One of the panels coinciding with one of the two main longitudinal faces functions as a lid, secured by a longitudinal flap sealed along one of the two adjoining narrower longitudinal faces. The lid in this instance cannot be closed stably once the seal is broken, and in effect the general practice is to discard these cartons once opened since they do not protect the packets thereafter during the period of consumption. Another carton of comparable type consists in a rigid wrapper appearing as a container, of cupped embodiment, with a similarly cupped lid hinged to the container in such a manner that one open end of the selfsame container can be closed. The lid is retained in the closed position by means of a frame projecting from the open end of the container. These cartons are designed to serve as storage containers until all of the packets they hold have been used up, although the flat diecut blanks from which they are fashioned require a relatively large quantity of wrapping material for their preparation and there is a significant amount of waste wrapping material generated in manufacture. Moreover, a lid hinged to one end of the container affords ease of access only to those packets in the container that are positioned nearer to the open end, whereas the user is unable to see the packets positioned at the bottom of the container. The object of the present invention is to provide a rigid wrapper that will permit of overcoming the aforementioned drawbacks simply and economically. Disclosure of the Invention The stated object is realized according to the invention in a rigid wrapper for a plurality of packets of cigarettes, typically of parallelepiped geometry presenting two end faces, and four side faces of which two constitute a bottom and a top, characterized in that it comprises an openable cover coinciding with at least one of the faces, rotatable about a relative hinge between a position in which the wrapper is closed and an open position affording access to the inside of the wrapper, and in that the cover is furnished with at least one guiding and stabilizing member lying in a plane transverse to the hinge . The invention will now be described in detail, by way of example, with the aid of the accompanying drawings, in which: -figure 1 illustrates a rigid wrapper according to the present invention, viewed schematically and in perspective; -figure 2 shows the wrapper of figure 1, viewed schematically and in perspective, illustrating a first preparatory step of the opening procedure; -figure 3 shows the wrapper of figure 1, viewed schematically and in perspective, and ready to be opened; -figure 4 shows the wrapper of figure 1, viewed schematically and in perspective, illustrating an intermediate step of the opening procedure; -figure 5 shows the wrapper of figure 1, viewed schematically and in perspective and fully opened; -figure 6 is the schematic plan view of a diecut blank from which to fashion the wrapper illustrated in figures 1 to 5. With reference to figures 1...5 of the accompanying drawings, 1 denotes a rigid wrapper or carton of substantially parallelepiped geometry that serves to contain a plurality of packets 2 of cigarettes, shown in figures 4 and 5. In the example of figures 1 to 5, the wrapper 1 exhibits an elongated appearance referable to a predominating longitudinal axis L, presenting four side faces 3, 4, 5 and 6 which extend parallel to the axis L and coincide respectively with four side walls 7, 8, 9 and 10 coinciding in turn with the front, top, back and bottom of the wrapper 1. Also indicated are two end faces 11 and 12 disposed transversely to the axis L, afforded by respective transverse walls 13 and 14 constituting the flanks of the wrapper 1. As discernible from figures 1 and 2, the front 7 comprises a removable portion 15 of substantially rectangular appearance delimited peripherally by a tear and/or perforation line 16. The length dimension of the removable portion 15 as measured along the predominating axis L is substantially identical to that of the front 7, whereas the width dimension, measured transversely to the axis L, is less than that of the front 7. In particular, the removable portion 15 is placed centrally in relation to the front 7, in such a way that the two branches of the tear line 16 lying parallel to the predominating axis L, denoted 16a and 16b, are equidistant from the two corner edges of the wrapper 1 along which the front 7 meets the bottom 10 and the top 8, respectively. Also illustrated in figures 1 and 2 is a tab 17 integral with the removable portion 15, delimited by a further tear and/or perforation line 18 in the transverse wall 14 coinciding with the end face denoted 12. As illustrated in figures 2 and 3, the wrapper 1 comprises an openable cover 19 behind the front 7, rotatable about a respective hinge line 20 between a position in which the wrapper 1 is closed (see figure 3) and a position in which the wrapper 1 is fully open (see figure 5) allowing the packets 2 to be withdrawn. More precisely, the hinge line 20 and the bottom branch lβa of the tear line 16 extend mutually parallel and substantially coincide one with another. The front 7 exhibits a portion denoted 7a lying between the bottom branch 16a of the tear and/or perforation line 16 and the corner edge joining the front 7 and the bottom 10 of the wrapper 1, and a portion denoted 7b lying between the top branch 16b of the tear and/or perforation line 16 and the corner edge joining the front 7 and the top 8, both of which serve to restrain the packets 2 inside the wrapper 1. In the same way as described previously for the removable portion 15, the cover 19 can be placed centrally in relation to the side face 3, in such a manner that the hinge 20 and the free edge 21 lie equidistant from the corner edges of the wrapper 1 along which the front 7 meets the bottom 10 and the top 8, respectively: in short, so that the outline of the cover 19 coincides substantially with the tear line 16 of the removable portion 15. As discernible from figures 4 and 5, the cover 19 comprises two guiding and stabilizing members 22 occupying respective planes disposed transversely to the hinge 20 and integral with the two opposite lateral edges 23 of the cover 19. More exactly, each one of the two members 22 is interposed and slidable between a respective transverse wall 13 and 14 and the packets 2 inside the wrapper 1. As indicated in figure 5, the free edge 21 of the cover 19 is provided with a reinforcing fold 24 and fashioned with a cutaway portion 25, positioned at an intermediate point along the fold, by means of which to pull the cover 19 open. With reference now to figure 6, the wrapper 1 is fashioned from a flat diecut blank 26 of which the component parts will be referred to where possible using the same numbers, primed, as those used to identify the corresponding parts of the wrapper 1. The blank 26 appears substantially rectangular in shape and exhibits two longitudinal crease lines, denoted 27 and 28, also a plurality of transverse crease lines denoted 29...34. The transverse crease lines 29...34 combine with the longitudinal crease lines 27 and 28 to define a succession of panels compassed between the selfsame longitudinal crease lines, namely a first central panel 9' extending between the transverse crease lines denoted 32 and 33, and a second panel 10' and a third panel 8 ' one on either side of the central panel 9', extending between the transverse crease lines denoted 31 and 32 and 33 and 34 respectively. The third panel 8' is joined along one transverse crease line 34 to a fourth and endmost panel 7', whilst the second panel 10' is joined by way of a band 35 extending between the two transverse crease lines denoted 31 and 30 to a fifth panel 19', and this in turn is joined along the remaining crease line 29 to a sixth and endmost panel 24'. The first panel 9' coincides with the back 9 of the erected wrapper 1, the second panel 10' with the bottom 10, the third panel 8' with the top 8, the fourth panel 7' with the front 7, the fifth panel 19' with the openable cover 19 and the sixth panel 24' with the reinforcing fold 24. The fourth panel 7' exhibits the tear and/or perforation line 16 serving to define the removable portion 15 of the wrapper 1, and in particular, the bottom branch 16a of the line delimits the bottom portion 7a of the front 7 and the top branch 16b of the line delimits the top portion 7b. The transverse crease line 30 separating the fifth panel 19' from the band 35 coincides with the hinge line 20 of the cover 19 and, more exactly, the band 35 will be positioned behind and breasted with the bottom portion 7a of the fourth panel 7' in the erected wrapper 1. The first panel 9' is associated by way of the longitudinal crease lines 27 and 28 with a first pair of flaps 36 destined to become the end walls or flanks 13 and 14 of the erected wrapper 1. The second panel 10' and the third panel 8' are associated by way of the two longitudinal crease lines 27 and 28 with a second and a third pair of flaps 37 and 38 destined to function as end folds securing the bottom 10 and the top 8 of the erected wrapper 1 to the flanks 13 and 14, as indicated by the phantom lines in figure 3. The fourth and endmost panel 7' is associated by way of the longitudinal crease lines 27 and 28 with a fourth pair of flaps 39 functioning as end folds by which the front 7 of the wrapper 1 is secured to the flanks 13 and 14, as illustrated in figure 3. Finally, the fifth panel 19' is associated by way of the longitudinal crease lines 27 and 28 with a fifth pair of flaps 22' destined to function as the guiding and stabilizing members 22 of the cover 19. The blank 26 also exhibits a hole 40 positioned at an intermediate point on the transverse crease line denoted 29 and in such way that when the sixth panel 24' is folded back and flattened against the fifth panel 19', the resulting void will provide the cutaway portion 25 by means of which to pull the cover 19 open. In addition, one of the flaps 39 associated with the fourth panel 7 ' will present the aforementioned tear and/or perforation line 18 serving to delimit the tab 17, which exhibits a substantially U-shaped outline and is positioned to coincide with a gap in the tear and/or perforation line 16 delimiting the removable portion 15 of the wrapper 1. It will be observed also that the flap 36 destined to overlap the flap 39 with the tear line 18 is fashioned with a notch 41 to facilitate the action of lifting the tab 17. The wrapper 1 is erected by bending and folding the various panels and flaps of the blank 26 in a manner that will be apparent from the foregoing description. Thereafter, when the moment comes to expose the contents, the user will grip the tab 17 of the removable portion 15 and pull it back as illustrated in figures 1 and 2 so as to reveal the cover 19 underneath, whereupon it becomes possible to gain access to the inside of the carton, take out one or more packets 2 and reclose the cover 19. The advantages of the invention consist in the fact that the wrapper 1 can be kept intact for the duration of use as the packets 2 are consumed one by one, and moreover, as discernible from figure 5, the fact that the wrapper 1 can be exploited by retailers as a display carton, with the removable portion 15 carrying promotional messages printed directly on the carton material or on coupons of whatever type attached to the selfsame portion 15. Finally, as illustrated in figure 6, the blank 26 from which the wrapper 1 is fashioned is a diecut of substantially traditional type generating little waste, and consequently can be utilized on existing cartoners without the need for modifications of any great significance.
