Description

Packaging box for smoking articles

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

There is a constant demand for improved ergonomics and practical design of packaging boxes. One area in which this requirement prevails is the supply of one package of tobacco products, such as a cigarette package.

Cigarette packages must meet a series of challenging requirements. In particular, the package should not only be cheap and capable of mass production, but it should also be strong enough 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 lid integrally formed at an upper end. The cigarettes are placed longitudinally so that a user can remove the cigarettes with the ends of the cigarettes when the lid is open.

Nowadays, various smoking article box designs are also commonly used. For example, some designs include a side-sliding or side-opening mechanism. GB 2115386 A, WO 2004024295 A and WO 2011154822 A1 disclose packaging boxes of this type.

In this method, an inner packaging portion of a holding cigarette is disposed in an outer packaging portion. In a closed position, an opening of the inner packaging portion is covered by the outer packaging portion, but the inner packaging portion can be moved relative to the outer packaging portion to an open position through one side opening in the outer packaging portion to allow access to storage Cigarette inside.

In a sliding configuration, the inner packaging portion moves relative to the outer packaging portion in a linear motion, whereas in a swing configuration, the inner packaging portion moves relative to the outer packaging portion in a motion that includes at least some rotation. In these and other configurations, consumers may complain that once some cigarettes have been removed from the inner packaging portion, the hardness of the inner packaging portion is reduced when the user grasps the inner packaging portion in the open position of the box. . This reduction in hardness can sometimes cause the inner packaging portion to be partially crushed by the user, thereby potentially damaging the structural rigidity of the remaining cigarette and the inner packaging portion.

This disadvantage becomes even more important in the case of a packaging box in which the inner packaging portion has rounded or chamfered corners between its front wall, rear wall, and side wall.

Therefore, there is a need to improve the hardness of a smoking article packaging box having a sliding or swing opening mechanism, and specifically the hardness of its inner packaging portion.

In a representative example, the fold lines 11 and 12 each consist of a plurality of creases adapted to form a rounded corner for the outer packaging portion 2. However, the fold lines 11 and 12 may also be formed by forming a single crease line of a square corner package or a double crease line forming a chamfered corner.

When the outer packaging portion 2 is formed, the top reverse panel 204 and the side top reverse panel 208 are glued to a lower side of one of the top reverse panels 205.

Similarly, one bottom wall 24 of the outer packaging portion 2 is formed by at least two bottom reverse panels 206, 207 hinged on 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 reverse panel 209 extending on one bottom side of the connection panel 203 to make. When the outer packaging portion 2 is formed, the bottom back panel 206 and the side bottom back panel 209 are glued to the upper side of one of the bottom back panels 207. The outer packing portion 2 further includes a front restraining flap and a rear restraining flap (not shown in FIGS. 1A and 1B) to hold the inner packing portion 3 in the open position. These suppression flaps are advantageously made of side flaps 210, 211 extending from the rear main panel 202 and the front main panel 201, respectively. When the outer packaging portion 2 is formed, the flaps 210 and 211 are restrained from folding inward against one of the front main panel 201 and the rear main panel 202. It should also be understood that the suppression flaps are not glued to the inner surfaces of the front main panel 201 and the rear main panel 202, but are only folded and inserted to allow the material to enter the wings of the completed outer packaging part 2 and the front wall 21 and the rear wall. Between 22.

The inner packaging portion 3 includes a front wall 31 and a rear wall 32 which are opposed to each other when the inner packaging 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 are connected to the bottom wall 33, the front wall 31, and the rear wall 32 to define a casing opened at the top and containing the cigarette bundle B.

The inner packaging portion 3 is formed by folding a cardboard blank 300 (illustrated in Fig. 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 packaging portion 3, respectively. The two main panels 301 and 302 are connected at one bottom side by a connection panel 303 to form a bottom wall 33 of the inner packaging portion 3.

Each of the main panels 301 and 302 includes a top cut-out portion 310 and 311 to define a casing and a cigarette which are received in the inner packaging portion 3 before and after. Preferably, the cut-out portions 310 and 311 are symmetrical with respect to the connection panel 303 in the main panels 301 and 302.

In addition, the front suppression tongue 312 and the rear suppression tongue 313 are provided in the main panels 301 and 302. The suppression tongues 312 and 313 are disposed in the cutout portions 314 and 315 of the main panels 301 and 302, preferably in a symmetrical position with respect to the connection panel 303. The suppression tongues 312, 313 are advantageously provided to form a suppression member in the inner packaging portion 3 that is complementary to the suppression flaps 210, 211 of the outer packaging portion 2 to restrict the movement of the inner packaging portion 3 in the open position and by suppressing the tongue The hooking engagement between the flaps 210, 211 of the sheets 312, 313 in the outer packaging portion 2 and the front and rear walls prevents the inner packaging portion 3 from being completely pulled out of the outer packaging portion 2.

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

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

When forming the outer packaging portion 3, the main panel 302 is first brought into a position perpendicular to the connection panel 303 and the bottom tabs 308, 309 glued to one of the inner surfaces of the connection panel 303, thereby side-reversing the panels 304, 306. Maintained to fold around its respective fold lines in a vertical orientation relative to the main panel 302. Next, the main panel 301 is also brought to be perpendicular to the connection panel 303 and the side reverse panels 305 and 307 of the main panel 301 are respectively glued to one of the side reverse panels 304 and 306 of the second main panel 302 to form the inner packaging portion 3 .

As shown in FIG. 2, one of the disadvantages of the prior art side-sliding packaging (and side-swing packaging) (especially when the inner packaging part has rounded corners as shown here) can be: once the inner packaging part 3 parts It is empty, and reduces the hardness of the front wall 31 and the rear wall 32 of the inner packaging portion when the inner packaging portion is held by the user in the open position of the packaging box. This reduction in hardness causes the inner packaging portion 3 to be partially crushed by the compressive force Fc exerted substantially perpendicular to the front wall and the rear wall by grasping the inner packaging portion by a user's finger. This crushing of the inner packaging portion can damage the structural integrity of the remaining cigarettes and the inner packaging portion. This also provides users with a negative impression about the quality of the box.

To address this shortcoming, the present invention provides an improved packaging box 10 as shown in FIGS. 5A to 12 and described below.

A first embodiment of a packaging box according to the present invention is shown in FIGS. 5A and 5B, and the embodiment is shown in a closed position and an open position, respectively. As appears in these drawings, this The inventive packaging box 10 includes an outer packaging portion 2 as known from the prior art sliding packaging previously described in relation to FIGS. 1 to 4 and an inner packaging portion 3 that is slidable between a closed position and an open position. However, according to the present invention, the packaging box 10 further includes a reinforcing member 4 structurally designed to increase the resistance of the front wall 31 to the compressive force. In this embodiment, the reinforcing member 4 can advantageously take the form of a reinforcing plate 40 as shown in FIG. 6. This reinforcing plate 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 packaging portion 3, A reinforcement plate 40 is applied to the top that can abut against at least one (preferably both) of the front wall 31 and the back wall 32 to provide (as represented in FIG. 8) an additional layer of reinforcing material to increase the front The wall 31 and / or the rear wall 32 resists the compressive force applied by the user when holding the inner packaging portion 3 (as shown in FIG. 2), which compression force easily crushes the inner packaging portion and forces the front wall And the back walls face each other.

Preferably, the reinforcing plate 40 further includes side panels 42 and 43 hinged on the lateral sides of the main panel 41 along the fold line. These side panels 42 and 43 further provide corners and side walls 34 and 35 of the main panel 41 extending to the inner packaging portion 3, and thereby improving at least one of the front wall 31 and the rear wall 32 and the inner packaging portion. The resistance to the compressive force of at least one of the corners between at least one of the side walls of 3, as can be seen from FIG. 8, which abuts the side walls 34, 35 of the inner packaging portion 3 and its front rounded corners The side panels 42 and 43 of the reinforcing plate 40 are applied.

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

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

However, the reinforcing plate 40 may also eliminate the bottom tongue 45 and show the bottom side or any other shape and is provided as a stack for use during the manufacture of the packaging box 1.

The reinforcing member 4 for the packaging box 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 packaging portion 3 or an inner surface. A preferred embodiment has a reinforcing member 4 provided on the inside of the inner packaging portion 3, for example, by a reinforcing plate 40 as described above and shown in FIGS. 6 to 8. In fact, providing the reinforcing member 4 inside the inner packaging portion 3 allows one of the front wall 31 and the rear wall 32 to be smoother and smoother on the outer surface. This is for the inner packaging portion 3 to be in the outer packaging portion 2 between the closed position and the open position. Proper sliding is preferred.

A method for manufacturing a packaging box 10 according to the present invention is schematically shown in FIG. 9, in which a reinforcing plate 40 as shown in FIG. 6 is provided as a reinforcing member 4 for the inner packaging portion 3.

In this embodiment, the reinforcing member for the inner packaging part 3 of the packaging box is provided as an integrated part for forming an alternative blank 300 'of the inner packaging part, 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. 4 referred to , 303, 304, 305, 306, 307, 308, 309. The blank 300 'also includes restraining tongues 312', 313 ', which are disposed on the cutout portions 314', 315 'of the main panels 301', 302 '. It is preferably in a symmetrical position with respect to the connection panel 303 '. Advantageously, the blank 300 'further comprises reinforced reverse panels 310', 311 ', which extend at one end of the main panel 301', 302 'opposite to the connection panel 303' and are hinged at this end along a folding line 17 ', 18' So as to be folded against the corresponding main panels 301 ', 302' before forming the inner packaging portion as shown in FIG. 15, and thereby provide an integrated reinforcing member for the main panels 301 ', 302' of the blank 300 'and The inner packaging part 3 is obtained in the same manner as previously described with reference to FIG. 4.

Preferably, cutout openings 312 ', 313' of conventional shapes (pentagons in the representative example) are also provided in the blank 300 ', so that even if the reversed panels 310', 311 'are reinforced against these main panels, Top cutouts can still be provided in the main panels 301 ', 302'. These top cutouts then provide lateral access openings in the front wall 31 and back wall 32 of the inner packaging portion 3 for easier access to cigarettes, as shown in Figure 5B.

The use of a blank 300 'to form the inner packaging portion 3 of the packaging box 10 of the present invention requires very few modifications to the manufacturing method described in FIG. In fact, this somehow leads to one of the methods being simplified. In fact, the feeding station S2 for individual reinforcement boards is no longer needed and can be removed from the line. The coated cigarette bundle B is directly supplied to the first blank feeding station S3 for the inner packaging portion 300 '. The individual blanks 300 'are fed to a pre-folding station (not shown in Fig. 9) in which both of the reinforced reverse panels 310', 311 'are folded, and are preferably glued to the inner surfaces of the main panels 301', 302 '. Next, a wrapped cigarette bundle B is positioned on 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 the station S4 as previously described. Then, the rest of the manufacturing procedure is the same as that in the stations S5 and S6 described earlier to obtain a finished packing box 10.

The packaging box 10 of the present invention provides an improved and reinforced packaging box having a sliding opening mechanism which can better resist compression force. Although the present invention has been described with reference to a diagram showing a packing box with a side-sliding opening mechanism, it should be noted that the strengthening principle will be applied to a side-opening mechanism having a side-swing opening mechanism that rotates within an outer-package portion Box.
