Definitions

  • the present invention relates to a method of producing overwrap material, and to a pack covered with the material obtainable by such a method.
  • the present invention relates to packs for tobacco products, typically cigarette packets, and indeed reference is made to products of this type in the following specification, albeit implying no limitation in scope.
  • packets of cigarettes are provided with a protective outer wrapper of transparent heat-shrinkable material, referred to generally as overwrap material.
  • Dedicated packaging machines first envelop each successive pack in the overwrap material and then apply heat to the selfsame material, causing it to tighten against the outer faces of the pack.
  • the ribbon is decoiled continuously from a roll and applied, by welding or gluing, to a strip of overwrap material moving continuously along a predetermined feed direction.
  • a succession of U-shaped notches can then be fashioned in the overwrap material, placed along the line of the ribbon.
  • Each notch serves to free one end of the ribbon, thereby creating a tab that can be gripped and pulled to break open the pack neatly and easily.
  • the strip of wrapping material with its bonded ribbon is cut into discrete leaves, each providing one protective wrapper, and fed to the packaging machine.
  • the ribbon With the wrapper in place around the finished pack, the ribbon will be positioned on the inside of the overwrap material, peripherally adjacent to one end face on all sides, in such a way that the material can be torn in a direction transverse to its longitudinal dimension.
  • the ribbon is located near the top end face, so that when pulled along the tear line, the wrapper will divide into two portions: a smaller portion enveloping the end face, and a larger portion enveloping the main body of the packet.
  • the object of the present invention is to provide a method of producing overwrap material, also a pack furnished with an easily removable material obtained by such a method.
  • the stated object is realized according to the present invention in a method of producing overwrap material that includes the steps of causing a continuous strip of overwrap material to advance along a predetermined feed path in a predetermined feed direction, piercing a predetermined area of the strip of overwrap material with at least one slit or incision having a geometrical component transverse to the feed direction, and applying a ribbon of small transverse dimensions to the strip, along the predetermined area.
  • the stated object is realized similarly in a pack furnished with a protective wrapper, consisting in a leaf of overwrap material and a ribbon of small transverse dimensions bonded to a predetermined area of the material, wherein the wrapper presents at least one slit made in the predetermined area of the overwrap material and having a geometrical component transverse to the longitudinal dimension of the ribbon of small transverse dimensions.
  • FIG. 1 is a perspective illustration showing the preparation of an overwrap material in accordance with the present invention
  • FIGS. 2 to 6 show different solutions for the embodiment of a detail in the illustration of FIG. 1 , viewed in plan from above;
  • FIG. 7 is a perspective illustration showing a packet of cigarettes furnished with the overwrap material
  • FIG. 8 is a perspective illustration showing a packet of cigarettes furnished with the overwrap material, in which the material is partially torn.
  • the invention relates to a method of producing overwrap material 1 .
  • a continuous strip of preferably transparent and heat-shrinkable overwrap material 1 is caused to advance along a predetermined feed path “P” in a predetermined direction “A”.
  • a predetermined area 2 of the advancing strip 1 is provided with at least one slit or incision 4 having a geometrical component transverse to the aforementioned direction “A”.
  • the step in question involves creating a succession of such slits 4 through the agency of suitable cutting or punching means 5 composed of a main roller 5 a carrying a blade 6 , and a matching anvil roller 5 b .
  • the two rollers 5 a and 5 b are set in contrarotation about respective axes extending transversely to the aforementioned feed direction “A”.
  • the blade 6 presents a profile selected according to the shape of the slit 4 and strikes against the anvil roller 5 b with each rotation of the main roller 5 a , producing a slit 4 at each stroke.
  • a ribbon 7 of small transverse dimensions is applied to the strip of overwrap material 1 ; the ribbon 7 is decoiled from a roll 8 , directed continuously downstream of a diverting roller 8 a along a path “P1” parallel to the feed path “P”, and applied to the aforementioned area 2 of the strip in parallel alignment with the feed direction “A”.
  • the ribbon 7 is bonded utilizing an ultrasonic welding unit 3 of familiar type, not described in detail.
  • the slits 4 are cut before applying the ribbon 7 , so that the ribbon can be positioned relative to the selfsame slits.
  • the ribbon 7 is shown placed over a central portion 4 a of the slit 4 , so that the two respective ends 4 b of the slit will be located on opposite sides of the ribbon 7 .
  • the ribbon 7 can be placed over one end 4 b of the slit 4 , as illustrated clearly in FIG. 4 where the slits are shown staggered one from the next, or in a part of the area 2 adjacent to but not effectively coinciding with the slits 4 .
  • the slits 4 are cut parallel one with another and appear substantially rectilinear, extending at right angles to the feed direction “A” and to the longitudinal dimension of the ribbon 7 .
  • the slits 4 are cut parallel with one another and angled obliquely, relative to the longitudinal dimension of the ribbon 7 .
  • the slits 4 can be staggered one from another on opposite sides of the ribbon 7 .
  • FIGS. 5 and 6 illustrate a further example in which the slits 4 are generated as chevrons, each presenting a vertex 9 that coincides with the line of the ribbon 7 .
  • the chevron slits 4 can be disposed, as in the example of FIG. 5 , with the vertex 9 oriented along a tear direction “B” of the narrow ribbon.
  • the selfsame slits 4 can be disposed with the vertex 9 oriented in a direction opposite to the tear direction “B” of the ribbon 7 , as in FIG. 6 .
  • the step of applying the ribbon 7 to the strip of overwrap material 1 is followed by a step of forming a U-shaped notch 10 in the aforementioned area 2 of the strip.
  • the U-shaped notch 10 is positioned between two successive slits 4 of the type cut previously, and serves to create a pull tab 11 at one end of the ribbon 7 , as will be described in due course.
  • a succession of the U-shaped notches 10 will be generated through the agency of a further blade 12 of conventional type (not illustrated), by which the ribbon 7 is cut transversely.
  • the strip of overwrap material 1 is divided up into discrete lengths, or leaves 13 , which are then fed into an overwrapping unit not illustrated in the accompanying drawings, being of conventional type and only incidental to the present invention.
  • the step of dividing the strip of overwrap material 1 into leaves is effected by a pair of contrarotating cutter rollers 14 equipped with respective blades 14 a .
  • Each leaf 13 cut by the rollers 14 presents a succession of slits 4 and one U-shaped notch 10 .
  • the strip of overwrap material 1 might be wound onto a reel (not illustrated) for use by the overwrapping unit.
  • the overwrap material 1 obtained by the method thus described is utilized for packs 15 of the type illustrated in FIGS. 7 and 8 .
  • the pack 15 of FIGS. 7 and 8 consists in a packet of cigarettes, around which the overwrap material 1 provides a protective outer wrapper 16 .
  • the wrapper 16 appears with the aforementioned ribbon 7 extending peripherally around one end face of the pack 15 .
  • the ribbon 7 is disposed with the tear direction “B” extending parallel to its own longitudinal dimension, and occupying a plane transverse to the longitudinal dimension of the pack 15 .
  • the wrapper 16 is opened by hand, gripping the tab 11 of the ribbon 7 and pulling. This causes the ribbon 7 to break the overwrap material 1 along the aforementioned tear direction “B” until the slit 4 is encountered.
  • the slit 4 shown perpendicular to the ribbon 7 in FIG. 7 , will at this point initiate two new break lines 17 departing and diverging from the line of the ribbon 7 on either side.
  • wrapper 16 shown in FIGS. 7 and 8 presents just one slit 4 , any given number of such slits 4 could be provided in order to facilitate the removal of the material 1 , depending on the size of the pack 15 .
  • the pack 15 does not need to be extracted from the wrapper 16 once a tear has been made with the ribbon 7 .
  • the action of pulling the ribbon 7 serves also to initiate the break lines 17 and allow the wrapper 16 to be torn off completely, without the material sticking fast to the outer faces of the pack 15 . Accordingly, the pack 15 is spared any damage that might be caused in the attempt to remove portions of the overwrap material 1 that continue to cling to the outer surfaces.
