Definitions

  • the invention relates to a package for tobacco related articles and to a multiple pack comprising a plurality of packages for tobacco related articles. Further, the invention relates to a blank for manufacturing a package for tobacco related articles.
  • Tobacco related articles preferably smoking articles like e.g. cigarettes are often contained in disposable packages having a substantially cuboid or parallelepiped shape.
  • four side walls e.g. a front wall, a rear wall, a left wall and a right wall
  • the opening is typically covered by a lid that is usually hinged to the rear wall.
  • a variety of different packages are known ranging from soft packs to classical cigarette boxes. In the recent time, packages for tobacco related articles departing from the classical cuboid or parallelepiped shape are becoming more and more popular.
  • Auxiliary items e.g. a lighter or an ash tray are often desired to be attached to the respective package in order to prevent their loss.
  • a variety of different technical approaches to this problem is known in the prior art. They are ranging from holding frames to hook-and-loop fastener systems (Velcro straps) as exemplarily disclosed in document WO 2011/005855 A1 .
  • EP 2 017 179 A1 discloses a package having a magnetic fastener that allows attaching a similar package.
  • WO 01/53171 A1 discloses a package for tobacco related articles having an outer box comprising a bottom wall and side walls extending from the bottom wall and a magnetic data recording element is non-detachably fixed in the interior space.
  • a package for tobacco related articles has an outer box comprising a bottom wall and side walls (e.g. a front wall, a rear wall, a left and a right wall) extending substantially perpendicular from the bottom wall.
  • the outer box encloses an interior space and has an opening that is arranged opposite to the bottom wall or in a side wall of the package.
  • the package further comprises a permanent magnet that is arranged in the interior space and is non-detachably fixed in the interior space.
  • the permanent magnet may be arranged in close proximity to a longitudinal edge portion of the outer box.
  • the longitudinal edge portion is the region where adjacent walls of the outer box are connected.
  • a permanent magnet within the meaning of the term may be a conventional solid permanent magnet, a magnetic foil a magnetic paste, e.g. a polymer dispersion comprising magnetic particles or even a stack or arrangement of a plurality of smaller magnets acting together as one permanent magnet.
  • Non-detachably means that the permanent magnet is fixed to the package in such a way that a removal of the magnet is only possible by damaging or destroying the package at least partially.
  • the permanent magnet may be glued to the package.
  • the permanent magnet may be contained in a compartment for non-detachable fixation.
  • a self-adhesive fixation may be used for non-detachably fixing the permanent magnet.
  • a self-adhesive layer or a self-adhesive tape on the permanent magnet or on a surface of the package may be used for non-detachable fixation.
  • One or more of the previously mentioned means may be combined for non-detachably fixing the permanent magnet.
  • the magnet and the package constitute an integral item. This reduces the possibility that the magnet or parts of it may separate from the package.
  • the package for tobacco related articles is magnetically attachable to a variety of different everyday items, preferably household items, e.g. a refrigerator door, a metallic door frame, a metallic framework of a lamp or a table and is therefore easily retrievable and storable at a preferred place.
  • household items e.g. a refrigerator door, a metallic door frame, a metallic framework of a lamp or a table
  • magnetizable material for attaching the package.
  • the package is attached to the respective items by using a magnetic force.
  • the package is detachable without residue or leaving traces.
  • Another advantage is that no counterparts such as a frame or a pad for a hook and loop fastener are necessary.
  • the outer box can have a bevelled edge portion.
  • the package has at least partially a polygonal, hexagonal, octogonal or semi-octagonal or round cross-sectional shape.
  • This cross-sectional shape may relate to a plane substantially perpendicular to a maximum extension of the package.
  • a semi-octagon is an octagon that is half cut and has one plane surface that is perpendicular to the respective neighboring surfaces.
  • the bevelled edge portion defines edges relating to the above mentioned cross-sectional shapes.
  • the permanent magnet may then be non-detachably fixed to the bevelled edge portion of the outer box.
  • the outer box has a round edge portion.
  • the round edge portion may then also relate to the cross-sectional shape in a plane substantially perpendicular to a maximum extension of the package.
  • the permanent magnet may then be non-detachably fixed to the round edge portion of the outer box.
  • This arrangement of the permanent magnet in the interior space of the outer box of the package allows a bundle of packages to be coupled together.
  • the packages may be attached to each other or the whole bundle may be attached to a third item.
  • Single packages may be removed from or inserted into this bundle while a secure attachment between the single packages can be maintained.
  • the possibility of attaching a plurality of packages together so as to form a bundle of packages is advantageous for wrapping the bundle. Especially, if cigarette packages may be packed together in order to provide a bundle of cigarette packages, the handling of the bundle of packages during the packing process can be simplified.
  • the thickness of the wall of the outer box mainly defines the minimum distance between the permanent magnet that is located at the inside surface of the outer box and the respective item.
  • the holding force for magnetically attaching the package to a third item increases with decreasing distance between the permanent magnet and the respective (magnetizable) item to which the package should be attached.
  • the minimum distance causes a maximum holding force and therefore allows a secure attachment of the package.
  • the package further comprises an inner frame that is arranged in the interior space.
  • the permanent magnet may then be arranged between the inner frame and the outer box.
  • the inner frame is adjacent to an article compartment for accommodating tobacco related articles (for example cigarettes).
  • the inner frame may then cover the permanent magnet completely so as to separate the permanent magnet from the article compartment.
  • Packages for tobacco related articles e.g. a packet of cigarettes often comprise an inner frame for retaining the lid and holding cigarettes.
  • the frame forms a collar which may provide an abutment or contact surface for the lid together with walls of the outer box.
  • this inner frame may be applied for covering the permanent magnets. The permanent magnet is then kept out of reach of the user and not accessible, neither from the outside of the package nor from its inside.
  • the inner frame may extend over an entire length of the article compartment in a direction of a maximum extent of the side walls.
  • This design of the inner frame and outer box allows omitting further auxiliary parts (blanks or parts of it etc) for covering and holding the permanent magnet. This is advantageous for a cost effective production of the package.
  • the inner frame may be configured so as to cover a bottom surface of the article compartment.
  • the inner frame may also be configured to cover at least the entire length of one of the side walls or front walls.
  • an edge portion of the inner frame facing the edge portion of the outer box may be bevelled and the permanent magnet may then be non-detachably fixed to the edge portion of the inner frame.
  • This can be advantageous for an outer box having bevelled edge portions aligned with the edge portions of the inner frame.
  • the outer box may have rounded edge portions aligned with the bevelled edge portions of the inner frame
  • Attaching the permanent magnet to the outer box or to the inner frame may be advantageous as the permanent magnet or magnets may be attached to a respective blank portion before manufacturing (folding and assembling) the package. Since an attachment of the permanent magnet to a rounded edge portion may be technically challenging, fixing the magnet at the inner frame can be advantageous.
  • a dimension of said edge portion in a direction that is transverse to a direction of a maximum extent of the side walls can be smaller than a dimension of the bevelled edge portion of the inner frame in the same transverse direction.
  • the chamfered or bevelled edge of the inner frame along the longitudinal edge portion of the inner frame may be narrower than the chamfered or bevelled edge of the corresponding longitudinal edge portion of the outer box.
  • a plurality of permanent magnets are arranged in the interior space.
  • the direction of a magnetic field of the permanent magnets can then differ according to a specific pattern in accordance with aspects of the invention.
  • the plurality of permanent magnets may advantageously be arranged and configured such that the outbound magnetic fields of permanent magnets being arranged in different edge portions have different magnitudes and/or opposite prefixes, if the magnets are arranged in edge portions adjacent to the same side wall and at the substantially same longitudinal location (location in longitudinal direction along the edges of the packages).
  • outbound means directing outside the package.
  • the permanent magnets in the packages are advantageously arranged and configured such that the poles facing the inner surface of the outer box are opposite to each other from one edge portion to the next edge portion along the side walls (i.e. for example, along front wall, left wall, rear wall and right wall or in other words along the perimeter (or a circumferential line) of the outer box or the lid) at the same or substantially same longitudinal position.
  • This can be arranged by choosing the local polarity of a permanent magnet at one edge opposite to the local polarity of another permanent magnet at the same longitudinal position at another (consecutive) edge.
  • the edges are advantageously consecutive edges along the perimeter of the outer box.
  • the respective magnets are arranged in that a north-pole of magnet at a first bevel (edge portion) is directed to the outside of the package while for a magnet that is arranged at a neighboring bevel at the substantially same longitudinal position, the south-pole is directed to the outside of the package.
  • a plurality of permanent magnets may be arranged in the interior space and the permanent magnets may be arranged and configured such that the permanent magnets have opposite polarity on the surface of the permanent magnets facing towards the outside of the outer box, if they are at the substantially same location in longitudinal direction and at different edge portions adjacent to the same side wall.
  • the package is not only attachable to magnetizable metallic items but also to other packages of the same type.
  • the magnet or the plurality of magnets are then arranged to have opposite polarity in two packages which are to be coupled to each other, as different or opposite magnetic poles attract each other.
  • This aspect of the invention can advantageously be used to couple two packages to each other along a magnetic hinge.
  • a plurality of permanent magnets for example in a plurality of compartments
  • the plurality of permanent magnets may advantageously be arranged and configured such that the outbound magnetic fields of permanent magnets being arranged in different edge portions have different magnitudes and/or opposite prefixes and/or opposite outbound polarity in edge portions adjacent to the same side wall and at the substantially same longitudinal location (location in longitudinal direction along the edges of the packages).
  • the outbound polarity of permanent magnets in the edge portions (for example longitudinal edge portions) of the package may alternate from edge to edge along an imaginary line around the package (circumferential line) at the same (constant) longitudinal position.
  • the permanent magnets may advantageously be multipole magnets comprising a plurality of magnetic poles. A plurality of different magnetic poles is then arranged at one surface of the permanent magnet. Preferably, a maximum extension of the magnetic poles is transverse or longitudinal to a direction of a maximum extent of the walls (front, rear, left, right wall) of the outer box.
  • Multipole magnets within the meaning of the term are magnets comprising opposite magnetic poles at one surface.
  • a multipole magnet having a cuboid shape comprises two north and two south poles at one side of the cuboid.
  • the magnetic poles are arranged alternately, e.g. N/S/N/S. This is advantageous when attaching two or more packages of the same type to each other, e.g. in order to form a bundle or a multiple pack of packages.
  • the respective opposite magnetic poles need to face each other.
  • the arrangement of packages is very flexible.
  • multipole magnets having magnetic poles that extend in a longitudinal direction of the side walls, especially along the longitudinal edges where front and rear wall are connected to the left and right wall no significant vertical misalignment between neighboring packages can occur if they comply with the aforementioned magnetic matching condition.
  • multipole magnets as previously described is advantageous as this may relax the requirements on the polarity/direction of the magnetic field or prefix of the field of the magnets in the edge portions of a packet.
  • the plurality of permanent magnets may advantageously be arranged and configured such that the outbound magnetic fields of permanent magnets being arranged in different edge portions have different magnitudes and/or opposite prefixes (or polarity facing the inner surface of the outer box) if the magnets are arranged in edge portions adjacent to the same side wall and at the substantially same longitudinal location (location in longitudinal direction along the edges of the packages).
  • one or more permanent magnet may be arranged at each edge portion of the package.
  • the edge portions may be longitudinal or transversal edge portions.
  • the permanent magnets may be arranged in the longitudinal edge portions only.
  • At least one permanent magnet is manufactured from a magnetic material comprising rare earth elements.
  • At least one permanent magnet may comprise Neodymium (Nd), Iron (Fe) and Boron (B).
  • Nd Neodymium
  • Fe Iron
  • B Boron
  • At least one permanent magnet comprises a coating of preferably Nickel (Ni), Copper (Cu) and/or Gold (Au) which prevents the magnetic material from oxidation.
  • the permanent magnet provides a holding force of at least 350 g/cm 2 .
  • At least one permanent magnet can have a magnetic remanence between 300 mT and 900 mT.
  • the magnetic remanence may be between 500 mT and 650 mT.
  • the remanence may advantageously be between 570 mT and 600 mT.
  • a multiple pack comprising a plurality of packages according to one of the aforementioned aspects of the invention is provided.
  • a magnetic hinge is provided between neighboring packages, e.g. cigarette boxes, wherein the packages are preferably arranged so as to form a booklet having a magnetic hinge.
  • a magnetic hinge allows providing a booklet for smoking articles that is very flexible. Different types of packages even for different smoking articles may be attached so as to form a booklet. The single packages are interchangeable, e.g. another type or flavor of smoking articles may be added or replaced in the booklet.
  • the magnetic hinge allows two respective packages to be pivoted with respect to each other around the magnetic hinge. However, unlike other hinges made of folding lines in cardboard, the magnetic hinge can easily be disconnected and reconnected. Using mulitpole permanent magnets can be advantageous for forming a magnetic hinge between two packages.
  • a blank configured to manufacture a package for tobacco related articles according to the above aspects.
  • the package to be formed from the blank has an outer box comprising a bottom wall and further side walls (front, rear, left, right) extending from the bottom wall. Further, the outer box encloses an interior space and has an opening opposite to the bottom wall or in a side wall. Adjacent side walls of the outer box are manufactured by folding the blank along a creasing line extending in a direction of (for example, a maximum extent of) the side walls, wherein at least one permanent magnet is non-detachably fixed to a (inner) surface of the blank, such that the permanent magnet is arranged inside the package to be formed from the blank.
  • the blank is advantageous, because an attachment of the permanent magnets to the blank, i.e. before manufacturing the package is technically much easier compared to an attachment of the magnets to the package itself.
  • the blank comprises a blank portion that is configured to build an inner frame and a blank portion that is configured to build the outer frame.
  • a package for tobacco related articles may then be manufactured from the blank by folding the respective blank portions along a further creasing line extending in a longitudinal direction of a maximum extent of the side walls (front, rear, left, right wall) so as to arrange the at least one permanent magnet between the outer and inner frame.
