Description

Packing box for smoking articles

The present invention generally relates to a package of tobacco products, such as smoking articles. In particular, the present invention relates to an improved package including a sliding or oscillating cavity and a method for constructing the package.

The ergonomic and practical design of the improved packaging box is constantly being requested. One of the areas in which this requirement is prevalent is the supply of a package of tobacco products, such as a cigarette package.

Cigarette packs must meet a range of challenging requirements. In particular, the package should not only be inexpensive and capable of mass production, but should also be sufficiently robust to protect the cigarette, maintain its freshness and maintain its integrity after opening and closing the package in multiple sequences.

Today, the most common design of cigarette packs is characterized by a hinged lid package. In this design, a cardboard package is provided with a hinged cover integrally formed at an upper end. The cigarette is placed longitudinally so that a user can remove the cigarette by the end of the cigarette when the lid is opened.

Today, a variety of smoking article packaging designs are also commonly used. For example, some designs include a side slip or side swing opening mechanism. A package of this type is disclosed in GB 2115386 A, WO 2004024295 A and WO 2011154822 A1.

In this method, the inner packaging portion of one of the holding cigarettes is placed in an outer packaging portion. In a closed position, the outer package portion covers one of the openings of the inner package portion, but the inner package portion is movable to an open position relative to the outer package portion through one of the side openings of the outer package portion to allow access to be stored therein Cigarette inside.

In a sliding configuration, the inner package portion moves relative to the outer package portion in a linear motion, whereas in a swing configuration, the inner package portion moves relative to the outer package portion in a motion that includes at least some rotation. In such configurations and in other configurations, the consumer can complain that once the cigarette has been removed from the inner package portion, the hardness of the inner package portion is reduced when the user grasps the portion of the package that is within the open position of the package. . This reduced hardness can sometimes cause the inner package portion to be partially compressed by the user, potentially damaging the structural hardness of the remaining cigarettes as well as the inner package portion.

This disadvantage is furthermore important in the case where the inner packaging portion has a round or chamfered corner between its front wall, rear wall and side walls.

Therefore, there is a need to improve the hardness of a package of smoking articles having a sliding or swing opening mechanism and, in particular, the hardness of the inner packaging portion thereof.

Referring to Figures 1A and 1B, one of the so-called skid packs 1 is known from the prior art. The package includes an outer package portion 2 and an inner package portion 3. The inner package portion 3 is movable relative to the outer package portion 2 and in particular can be slid between a closed position as illustrated in Figure 1A and an open position as shown in Figure 1B.

The user can cause the inner package portion 3 to slide by pushing a portion of the inner package portion 3 exposed through one of the openings 26 in the outer package portion 2 by using a thumb or a finger. As can be seen in Figure 1B, once the inner package portion 3 has been pushed open through the opening 26 in the outer portion 2, The user can manually utilize the inner package portion 3 to fully open it and expose one of the cigarette bundles B contained after removing one of the protective foils on the first opening.

The outer package portion 2 includes a front wall 21 and a rear wall 22 which are opposed to each other when the outer package portion 2 is formed. The front wall 21 and the rear wall 22 are connected by a side wall 25, a top wall 23 and a bottom wall 24. An opening 26 is formed in the side wall 25.

The outer package portion 2 and the inner package portion 3 are coupled to each other in such a manner as to prevent the inner package portion 3 from being completely withdrawn and removed from the outer package portion 2. Furthermore, a retaining element can be provided to prevent accidental movement of the inner package portion 3 relative to the outer package portion 2. The mechanism for producing such effects can be understood by referring to Figs. 3 and 4, respectively, which are used to form a blank 200 for forming an outer package portion and a blank 300 for forming an inner portion.

The outer package portion is formed by folding and gluing a cardboard blank 200 (illustrated in Figure 3).

The top wall 23 of the outer package portion 2 is formed by at least two top counter panels 204, 205, and the top counter panels 204, 205 are hinged to form the outer package portion rear wall 22 and the front wall 21, respectively, the rear main panel 202 and a front One of the main panels 201 is on the top side. Preferably, the top wall 23 is further formed by a side top counter panel 208 extending over a top side of one of the side panels 25 forming the outer package portion 2, the connecting panel 203 being folded along The wires 11, 12 are attached to one of the longitudinal sides of the first and second main panels 201, 202. In the representative example, the fold lines 11, 12 are each formed of a plurality of folds adapted to form a rounded corner for the outer package portion 2. However, the fold lines 11, 12 may also be formed from a single crease line forming a square corner package or a double crease line forming a beveled corner.

When the outer package portion 2 is formed, the top and back panels 204 and the side top counter panels 208 are glued to the lower side of one of the top and reverse panels 205.

Similarly, one of the bottom walls 24 of the outer package portion 2 is formed by at least two bottom counter panels 206, 207 hinged to the bottom side of one of the rear main panel 202 and the front main panel 201. Preferably, the bottom wall 24 is further formed by a side bottom counter panel 209 extending on one of the bottom sides of the connecting panel 203. to make. When the outer package portion 2 is formed, the bottom back panel 206 and the side bottom counter panel 209 are glued to the upper side of one of the bottom back panels 207. The outer package portion 2 further includes a front restraining flap and a rear restraining flap (not shown in Figures IA and IB) to retain the inner package portion 3 in the open position. These restraining flaps are advantageously made from side panels 210, 211 that extend from the rear main panel 202 and the front main panel 201, respectively. When the outer package portion 2 is formed, the flaps 210, 211 are restrained from being folded inwardly against the inner faces of one of the front main panel 201 and the rear main panel 202. It should also be understood that the restraining flaps are not glued to the inner surfaces of the front main panel 201 and the rear main panel 202, but are only folded into place to allow material to enter the flaps and front wall 21 and rear wall of the finished outer packaging portion 2. Between 22.

The inner package portion 3 includes a front wall 31 and a rear wall 32 which are opposed to each other when the inner package portion 3 is formed. The front wall 31 and the rear wall 32 are connected by a bottom wall 33. A first side wall 35 and a second side wall 34 connect the bottom wall 33 and the front wall 31 and the rear wall 32 to define a housing that is open at the top and accommodates the bundle of cigarettes B.

The inner package portion 3 is formed by folding a cardboard blank 300 (illustrated in Figure 4). The blank 300 includes a first main panel 301 and a second main panel 302 to form the front wall 31 and the rear wall 32 of the inner package portion 3, respectively. The two main panels 301, 302 are joined on a bottom side by a connecting panel 303 to form the bottom wall 33 of the inner package portion 3.

Each of the main panels 301, 302 includes a top cutout portion 310, 311 to define a housing and a cigarette that are front and then received into the inner package portion 3. Preferably, the cutout portions 310, 311 are symmetrical with respect to the connection panel 303 in the main panels 301, 302.

In addition, the front restraining tongue 312 and the rear restraining tongue 313 are provided in the main panels 301, 302. The restraining tabs 312, 313 are disposed in the cutout portions 314, 315 of the main panels 301, 302, preferably in a symmetrical position relative to one of the connection panels 303. The restraining tabs 312, 313 are advantageously provided to form a restraining member in the inner package portion 3 that is complementary to the restraining flaps 210, 211 of the outer wrap portion 2 to limit movement of the inner wrap portion 3 in the open position and to inhibit the tongue The mutual hooking of the sheets 312, 313 between the restraining flaps 210, 211 of the outer package portion 2 and the front and rear walls prevents the inner package portion 3 from being completely withdrawn from the outer package portion 2.

In addition, the blank 300 includes longitudinal side counter panels 305, 307 and 304, 306 hinged to the longitudinal sides of the front main panel 301 and the rear main panel 302, respectively, along the fold lines 13, 14, 15, 16. In the representative example, the fold lines 13, 14, 15, 16 are each formed of a plurality of folds adapted to form a rounded corner for the outer package portion 2. However, the fold lines 11, 12 may also be formed from a single crease line forming a square corner package or a double crease line forming a beveled corner.

Preferably, additional bottom flaps 308, 309 are also provided on one of the side edges of the side counter panels 304, 306 to provide anchoring members for the side walls 34, 35 of the inner wrap portion 3 to the bottom wall 33.

When the outer package portion 3 is formed, the main panel 302 is first brought into a position perpendicular to the connection panel 303 and the bottom flaps 308, 309 glued to the inner surface of one of the connection panels 303, thereby the side counter panels 304, 306. The folding is maintained in a vertical orientation relative to the main panel 302 about its respective fold line. Next, the main panel 301 is also brought to be perpendicular to the connection panel 303 and the side counter panels 305, 307 of the main panel 301 are respectively glued to one of the side counter panels 304, 306 of the second main panel 302 to form the inner package portion 3. .

As shown in Fig. 2, one of the disadvantages of the prior art side slip package (and side slant package) (especially when the inner package portion has a rounded corner as shown here) may be: once the inner package portion 3 If it is empty, the hardness of the front wall 31 and the rear wall 32 of the inner package portion is reduced when the user grasps the inner package portion in the open position of the package. This reduced hardness causes the inner package portion 3 to be partially compressed under the compressive force Fc applied substantially perpendicular to the front and rear walls by grasping the inner package portion by the user's fingers. This compression of the inner packaging portion can damage the structural integrity of the remaining cigarettes as well as the inner packaging portion. This also provides the user with a negative impression of the quality of the package.

To address this shortcoming, the present invention provides an improved package 10 as shown in Figures 5A through 12 and described below.

A first embodiment of a package in accordance with the present invention is illustrated in Figures 5A and 5B, showing the embodiment in a closed position and an open position, respectively. As appears in these figures, this The package 10 of the present invention includes one of the outer package portions 2 and one of the inner package portions 3 slidable between a closed position and an open position as seen from the prior art slide package previously described with respect to Figures 1 through 4. However, in accordance with the present invention, the package 10 further includes a reinforcing member 4 that is structurally designed to increase the resistance of the front wall 31 to compressive forces. In this embodiment, the reinforcing member 4 may advantageously take the form of a reinforcing plate 40 as shown in FIG. The stiffener 40 includes a main panel 41 that is structurally designed to match (as shown in FIG. 7) at least one top (preferably at least one upper half) of the front wall 31 or the rear wall 32 of the inner package portion 3, A reinforcing plate 40 is applied to the top of at least one of the front wall 31 and the rear wall 32 (preferably both) to provide (as shown in Figure 8) an additional layer of reinforcing material to increase the front The wall 31 and/or the rear wall 32 resists the resistance of the compressive force exerted by the user grasping the inner package portion 3 (as shown in Figure 2), which compresses the pressure portion easily and forces the front wall And the back wall faces each other.

Preferably, the reinforcing panel 40 further includes side panels 42, 43 hinged to the lateral sides of the main panel 41 along the fold line. The side panels 42, 43 further provide corners and side walls 34, 35 of the main panel 41 that extend to the inner package portion 3, and thereby improve at least one of the front wall 31 and the rear wall 32 and the inner package portion The resistance of the compressive force of at least one of the corners between at least one of the side walls of 3, as seen in Figure 8, wherein the side walls 34, 35 of the inner package portion 3 and their front circular corners The side panels 42, 43 of the reinforcing panel 40 are applied.

The stiffener 40 is structurally designed to match at least the top side of the inner package portion 3, wherein a top opening is formed to access the interior of the inner package portion. For this purpose, the reinforcing plate preferably includes a top cut-away portion 44 having the same shape and size as the cut-away portions 310, 311 of the front wall 31 and the rear wall 32.

The reinforcing panel 40 can advantageously be formed from a roll of paperboard material, for example, a cardboard material that is identical or similar to one of the inner packaging portions 3. In this case, the reinforcing plate 40 further includes a bottom tongue 45 corresponding to the cut-away portion 44 in the top side of the main panel 41. Thereby, during manufacture of the package 10, the cut-away portion 44 is formed in each of the reinforcing sheets 40 after the tongue 45 of the previous reinforcing sheet is detached from a roll, as will be described in more detail below.

However, the stiffener 40 can also be used without the bottom tongue 45 and exhibiting a bottom side or any other shape and provided as a stack for use during manufacture of the package 1.

The reinforcing member 4 for the package 10 of the present invention may be provided on at least one of the front wall 31 and the rear wall 32 of the inner package portion 3 or an inner surface. A preferred embodiment has a reinforcing member 4 provided on the inside of the inner package portion 3, for example, by reinforcing one of the panels 40 as described above and illustrated in Figures 6-8. In fact, the provision of the reinforcing member 4 on the inner side of the inner package portion 3 allows a smoother and smoother outer surface of one of the front wall 31 and the rear wall 32, which is within the outer package portion 2 between the closed position and the open position of the inner package portion 3. A suitable sliding system is preferred.

The step d) of providing the reinforcing member 4 in the inner package portion 3 is advantageously performed before the inner package portion 3 is formed.

As shown in Figure 9, a bundle of cigarettes B made from a previously collected group of cigarettes wrapped in a protective foil is provided to a first station S1 of a packaging line, which will be a stiffened panel 40. The reinforcing member 4 in the form is fed from a feeding station S2 to each cigarette bundle B. The reinforcing plate 40 is individually detached or cut from a roll R in the feed station S2 and then provided with a glue dot from a glue applicator G. Next, the individual stiffeners 40 are transferred to a bundle of cigarettes B (as detailed in FIG. 10) by any suitable transport system T to adhere the stiffener 40, i.e., the main panel 41 and side panels of the stiffener 40 Adhered to one of the main faces and sides of the bundle B of cigarettes.

Next, the bundle of cigarettes B equipped with a reinforcing sheet 40 is conveyed to a first blank feeding station S3 by a conveying member (for example, an adsorption belt or the like), wherein the blank forming the inner packaging portion 3 of the package 10 is provided from the stack 300. In the first blank feeding station S3, the cigarette bundle B is positioned on one of the main panels 301, 302 such that the cut-away portion 44 of the reinforcing panel 40 is superimposed with one of the main panels 301, 302 corresponding to the cuts 310, 311. Next, the blank 300 is formed and glued in a first folding station S4 by folding (preferably according to the principle of longitudinal folding) to obtain the inner package portion 3, wherein the cigarette bundle is placed on the main wall and the side wall of the inner package portion 3. And in the housing between the bottom walls 31, 32, 33, 34, 35.

Preferably, a glue dot is provided on one of the outer surfaces of the reinforcing plate 40 during the transfer between the stations S1 and S3 to provide a reinforcing plate 40 that directly adheres to the inner surface of one of the main panels 301, 302 of the blank 300. Thereby, it is adhered to the front wall 31 or the rear wall 32 of the inner package portion 3 which has been completed at the exit of the station S4.

Once the inner package portion 3 containing a bundle of cigarettes B and the reinforcing sheet 40 is formed in the station S4, the inner package portion 3 is conveyed to a second blank feeding station S5 which provides one of the blanks 200 for the outer package portion 2. Next, the blank 200 for the outer package portion 2 is folded and glued around the first inner package portion 3 in a second folding station S6 to form the package 10 which is fully completed in the closed position as shown in Fig. 5A.

The reinforcing member 4 of the package 10 of the present invention can advantageously employ other forms than one of the reinforcing sheets 40 depicted in Figures 6-10 without compromising the quality or resistance of the finished package 10. .

A first variant of the reinforcing member 4 is shown in FIG. In this variant, the reinforcing member 4 In the reinforced panel 50, it comprises two main panels 51, 52 hinged to the longitudinal side of an intermediate connection panel 53 along the fold line. The two main panels 51, 52 are symmetrical to each other around the connecting panel 53, and each includes a cutout portion 310, 311 which is the same size and shape as the blanks 300 of the blank 300 of the inner package portion 3 of the package 1 of the present invention. One of the top cutout portions 54. In addition, the main panels 51, 52 are preferably substantially equal in width to the main panels 301, 302 of the blank 300 for the inner package portion 3, thereby being equal to the front wall 31 and the rear wall 32 of the inner package portion 3, and The attachment panel 53 has substantially the same width as the side walls 34, 35 of the inner package portion.

The reinforcing plate 50 is reinforced at the same time as it allows at least one of the front wall and the rear wall of the inner package portion and the side walls 34, 35 and the corners connecting the front wall and the rear wall (as shown in FIG. 12). It is especially advantageous.

The stiffener 50 is further advantageous because it does not require modification of the complete manufacturing process of the package 10 and only requires modification of the initial stage of positioning the stiffener 50 around the wrapped bundle of cigarettes B (as shown in Figures 13A and 13B). The reinforcing panel 50 is preferably provided in the form of a flat surface having a glue dot on one surface of each of the main panel (preferably the main panel and the connecting panel) (Fig. 11), and surrounding a wrapped bundle of cigarettes B (Fig. 13A) Further folding into a U shape causes the glued surfaces of the main panels 52, 53 to adhere to the outer surface of the bundle B, as shown in Figure 13B. Next, the coated bundle B is supplied together with the adhesive reinforcing sheet 50 to the first blank feeding station S3 as in the packaging line previously described in FIG.

Another embodiment of the package 10 of the present invention is depicted in Figures 14 and 15. In this embodiment, the reinforcing member for the inner packaging portion 3 of the package is provided as an integral member for forming one of the inner packaging portions in place of the blank 300', which is shown in FIG.

The blank 300' includes panels 301', 302', 303', 304', 305', 306', 307', 308', 309', which respectively correspond to the panels 301, 302 of the blank 300 of FIG. , 303, 304, 305, 306, 307, 308, 309. The blank 300' also includes restraining tabs 312', 313' that are disposed in the cut-away portions 314', 315' of the main panels 301', 302'. Preferably, it is in a symmetrical position relative to one of the connection panels 303'. Advantageously, the blank 300' further comprises a reinforced counter panel 310', 311' extending from the main panel 301 ', 302' opposite one end of the connection panel 303' and hinged at the end along a fold line 17', 18' So that it can be folded against the corresponding main panels 301 ', 302' before forming the inner packaging portion as shown in Fig. 15, and thereby providing an integrated reinforcing member for the main panels 301 ', 302' of the blank 300' and The inner package portion 3 is obtained in the same manner as previously described with reference to FIG.

Preferably, the cut-out openings 312', 313' of a conventional shape (in the representative example, a pentagon) are also provided in the blank 300' such that the reinforcing back panels 310', 311' are folded even if they have been folded against the main panels. A top cut-out portion can still be provided in the main panels 301 ', 302'. Next, the top cut-out portions provide lateral access openings in the front wall 31 and rear wall 32 of the inner package portion 3 for easier access to the cigarette, as shown in Figure 5B.

The use of a blank 300' to form the inner packaging portion 3 of the package 10 of the present invention requires very little modification to the manufacturing method described in FIG. In fact, this leads to some simplification of the method to some extent. In fact, the feed station S2 for the individual stiffeners is no longer needed and can be removed from the line. The coated bundle of cigarettes B is supplied directly to the first blank feeding station S3 for the inner package portion 300'. The individual blanks 300' are fed to a pre-folding station (not shown in Figure 9) in which one of the folded reinforcing back panels 310', 311' is, and preferably glued to the inner faces of the main panels 301', 302'. Next, a coated bundle of cigarettes B is positioned onto one or the other of the main panels 301', 302' and then the blank 300' is subjected to folding and gluing around the bundle B in station S4 as previously described. The remainder of the manufacturing process is then identical to the procedures in stations S5 and S6 previously described to obtain a completed package 10.

The package 10 of the present invention provides an improved and reinforced package having one of the sliding opening mechanisms that are more resistant to compression. Although the invention has been described with reference to a drawing showing a package having a side-slip opening mechanism, it should be noted that the principle of reinforcement will be applied to a side-opening mechanism having an inner packaging portion that rotates within an outer packaging portion.
