Description

  The present invention relates to a package for smoking articles, in particular exclusively for cigarettes.

  It is well known that packages for smoking articles such as cigarettes are made from a blank made of paperboard, such as cardboard, which includes a front and back panel connected by opposing side panels, and a bottom surface. Includes a panel and a lid. The lid may be configured in a structure called a flip top method.

  Such conventional packages have the problem that the panels, especially the front and back panels, bend, especially when the paper grain of the paperboard is parallel to the length of the package. Of course, we haven't been able to make packages with thinner cardboard to reduce costs, but such thin cardboard looks cheap to the user and makes a wider package. Is too weak to limit the package shape options.

  An internal frame is provided in a conventional flip top type package, and the lid can abut on the closed position, and a hooking portion is provided so that a portion other than the lid of the package and the outer peripheral portion of the lid extend on the same plane. It is known. The following patent document proposes to provide a ribbig on the surface of the inner frame that contacts the inner surface of the front panel of the package. However, this configuration uses a lot of space in the container and increases the overall material cost of the package.

FIG. 2 is a view of the package of FIG. 1 with the lid open. FIG. 3 is a schematic exploded view of the package of FIGS. 1 and 2. It is a front view of a package. It is a rear view of a package. It is a side view of a package. It is a bottom view of a package. FIG. 8 is a schematic diagram of a blank for producing the package of FIGS. FIG. 9 is a partial cross-sectional view taken along line A-A ′ of FIG. 8. FIG. 8 is a schematic diagram of equipment for stuffing cigarettes in the packages of FIGS. It is a schematic diagram of the embossing station in the installation of FIG.

  1-8 show a flip top lidded cigarette package formed by the blank shown in FIG. 8, which includes a front panel 2, a back panel 3, side panels 4, 5, a bottom panel 6 and Including the hinged lid 7, all are formed by bending and bonding selected portions of a blank made of sheet material overlaid with cardboard such as cardboard as shown in FIG.

  The package has a chamfered edge 8 extending longitudinally along the junction between the side panels 4, 5 and the front and back panels 2, 3.

  The lid 7 has an inclined side edge 9 and a front edge 10 positioned lower than the hinge line 11 of the lid in the closed state, and the upper edge 12 of the front panel and the side panels 2, 3, 4. And 13 are formed so as to correspond to the side edge and the front edge so that the lid is closed tightly. As shown in FIGS. 2 and 3, in this example, the package contains 20 cigarettes 14 and, as is known in the art, the lid 7 is opened by the tilting of the lid 7. It is easy to take out the cigarette in the state.

  An inner frame 15 made of sheet material such as cardboard overlapped is mounted in the upper part of the opening of the container, and is bonded by an adhesive, for example, so that the user can take out the cigarette 16. including. The inner frame 15 has an outer surface having the same width as the front and side panels 2, 3, and 4, the lid 7 is closed, and the outer surface is located on the same plane as the front panel and side panels 2, 4, and 5 The front and side panels 2, 3 and 4 are restricted along the chamfered edge 8 adjacent to the front panel to serve as a catch against which the lid can come into contact. . The inner frame 15 includes a flange 17 extending therefrom, which acts as a stopper for holding the lid 7 in the closed state.

  The front and back panels 2, 3 are provided with laterally extending strips 18 formed by embossing blanks described in detail below.

  The band 18 extending in the lateral direction includes the pleats shown in FIG. The thickness t of the band 18 is larger than the thickness r of the region 19 between the band 18. The region 19 may be formed by embossing, but other techniques may be used, such as, for example, scoring or tapping a paperboard material along the region 19 with a sharp blade.

  In the example described above, the pleats 18 extend over the entire width of the front and back panels 2, 3 and have equal widths w as shown in FIG. The regions 19 between the pleats 18 are straight and parallel to each other in this example. Furthermore, as shown in FIGS. 4 and 5, such pleats 18 </ b> A are also provided on the front and back surfaces of the lid 7.

  The pleats 18 have the effect of strengthening and strengthening the front and back panels 2, 3 of the package so that thinner paperboard material can be used to form the blank without losing strength when the package is assembled. This not only reduces material costs, but also reduces transportation costs due to the reduced weight of the package. The pleat 18A performs a similar function with respect to the lid 7.

  Further, the package is not affected by the direction of the paper pattern of the paperboard material by being strengthened by the pleats 18, and the strength of the paper pattern is not greatly changed in the front and back panels 2 and 3. It can be arranged in either the direction or the lateral direction.

  In addition, the use of the pleats 18 described above allows the package to be made wider than before with a special board thickness, allowing designers to think more freely about new package designs.

  In addition, the pleats 18 and 18A provide a holding surface that the user can feel on the outside of the package to help the user grasp the package and open the lid 7.

  The card used in package 1 weighs 180-300 g per square meter, for example 280 g, but by providing a band 18, a lighter material weighing 215 g or 200 grams per square meter can be obtained. It becomes possible to use. If the weight is reduced, the strength of the card becomes weaker, but this is improved by the installation of the band 18. The thickness of the card is usually 0.3 mm when it is embossed to form the band 18, and is 50% of that without embossing.

  A method for packing cigarettes in a package will be described with reference to FIGS. As shown in FIG. 10, the magazine 20 includes a plurality of blanks 1 ', which are substantially as shown in FIG. The blank may be pre-printed or pre-formed by fold lines in a manner well known in the art. The individual blanks are successively conveyed to an embossing station 21 where pleats 18 are embossed into preprinted blanks. The blank is then transported to the cigarette packing machine 22 to which the cigarette 23 is supplied. The cigarette packing machine 22 bends the blank to form the package 1, packs the cigarette in the inner frame 15, and packs it with aluminum foil (not shown).

  The packaging machine 22 operates in a manner well known to those skilled in the art to fold the blank as shown in FIG. 8 along the fold diagonal to form the package. The blank 1 'includes a front panel portion 2' and a back panel portion 3 'joined by a bottom panel portion 6'. The lid is formed by a lid panel portion 7 ', which is used to produce the lid top 24, the lid rear panel 25, the lid front panel 26 and the lid structure shown in FIGS. Re-entrant flaps 28-30 that are foldable in the direction.

  The side walls 4 and 5 of the package are formed of panel portions 4 ′, 4 ″, 5 ′ and 5 ″ belonging to the front panel portion 2 ′ and the back panel portion 3 ′, respectively. When the package is folded, the panel portions 4 ′ and 4 ″ and the panels 5 ′ and 5 ″ overlap each other and are bonded together to form the side walls 4 and 5.

  The chamfered edge 8 is formed from the region 8 ′ by bending the folding diagonal lines 31 and 32. When assembled, the lid 7 can be hinged along the hinge line 11.

  At first, the blank may not have the pleats 18 and 18A, and the transaction and the usage precautions may be printed in advance. They are continuously conveyed to the embossing station 21 and embossed using a tool as shown in FIG. Here, in order to emboss the surface of the blank, the pre-printed blank 1 ′ is placed in alignment with the embossing tool 34 moved in the direction of arrow A. The tool 34 includes a series of concave pleats 35 that become the mirror surface (form) of the convex pleats 18 formed in the blank, moves downward onto the blank 1 ', and forms the pleats in the blank by embossing, A blank having the configuration shown in FIG. 8 is produced.

  The embossed blank 1 'is then assembled as described above and transported to the cigarette packing machine 22 shown in FIG. 10 for packing cigarettes.

  Various improvements and modifications of the described package are possible within the scope of the present invention. In this specification, the number of pleats 18 in the front and back panels 2 and 3 is the same, but the number of pleats may be different. For example, the number of pleats 18 provided in the back panel 3 as compared with the front panel. There may be less. Further, the pleats 18 may not be provided on all of the front panels, and there may be a panel portion having a flat structure with no pleats on the surface.

  Furthermore, the package described above has a chamfered edge 8 but can be omitted if the package has a straight edge or a curved edge. Where curved edges are provided, the presence of pleats 18 allows the front and back of the package to be made rugged while using a relatively thin board material that can be easily deformed into curved edges.

  The pleats 18 need not have exactly the same width as described above, and the width may vary. Furthermore, the pleats need not be straight and may have curved edges. The pleats 18 need not extend across the entire width of the front and back panels 2, 3.

  The embossing tool at the embossing station 21 may also be a rotary embossing device, and other methods of forming a strip that does not require embossing will be apparent to those skilled in the art.

  Also, the blank may be manufactured together with the strip, so that the blank in the magazine 20 already has the strip and the embossing station 21 is not required.

  Although the present invention has been described in connection with a flip top lidded package, it also applies to packages for other smoking articles that do not require a lid, such as containers holding multiple flip top cigarette packages. it can.

  Obviously, many other variations and modifications are within the scope of the appended claims.
