Definitions

  • the invention relates to a cuboidal pack, in particular a cigarette pack, with an outer wrapper made of film, and with an open-ended tear-open thread fitted on the outer wrapper.
  • the invention also relates to a process and to an apparatus for producing such packs.
  • Packs of different shapes and forms are frequently provided, in order to protect the pack contents, with an outer wrapper made of film or of a comparable packaging material.
  • an outer wrapper made of film or of a comparable packaging material.
  • the latter is frequently provided with a tear-open thread or tear-open strip, which is fastened on the outer wrapper by adhesive bonding or sealing.
  • This outer wrapper can be severed, and thus removed, by virtue of the tear-open thread being gripped at a grip end.
  • the invention is concerned with such packs, to be precise, in particular with cigarette packs configured as a cuboidal rigid pack (made of thin cardboard).
  • the object of the invention is to fit a tear-open thread or tear-open strip on the outer wrapper of a pack such that, when the tear-open thread is used, the entire outer wrapper is reliably removed.
  • the pack according to the invention is characterized in that the tear-open thread, in the region of the large-surface-area front wall and/or of the corresponding rear wall of the pack, extends approximately diagonally from one (top) pack corner to a (bottom) pack corner.
  • the (more or less) diagonal course taken by the tear-open thread in the region of at least one of the large-surface-area pack walls ensures that the outer wrapper is optimally severed by the tear-open strip, with the result that the remaining parts of the wrapper can easily be drawn off from corners of the pack.
  • the invention is thus suitable, in particular, for cigarette packs of the hinge-lid-box type with shrink film as the outer wrapper.
  • the tear-open thread is preferably arranged such that a transversely directed, rectilinear thread section is formed in the region of the narrow, upright side surfaces, to be precise adjacent to an end wall, on the one hand, and to a base wall, on the other hand, and that, by means of these thread sections, diagonal thread sections of the front wall and rear wall, these running in the same direction in each case, are connected to one another.
  • the tear-open thread or tear-open strip is applied to the material web, made of film, paper or the like, during continuous transportation of the same, the tear-open thread being moved by precisely controlled thread guides, in accordance with the thread configuration which is to be produced, transversely to the conveying direction of the (film) web.
  • the continuous tear-open thread is provided with a more or less meandering configuration, with rounded transitions, on the material web.
  • thread sections that is to say tear-open threads or tear-open strips which are completed in terms of shape and length, are applied to the continuous (film) web.
  • the tear-open strips are severed from a thread web by a contoured cut and positioned on the web directly in accordance with the position of a blank for the outer wrapper.
  • the apparatus according to the invention for applying a continuous tear-open thread or tear-open strip to a continuously moving web has a particular guide element for the tear-open thread, namely with a guide roller.
  • This has a double function, that is to say it serves for positioning the tear-open thread on the web and, at the same time, as a guide element.
  • the guide roller is moved, by a controlled gear mechanism, in the direction transverse to the web or transverse to the conveying direction of the same, with the result that the tear-open thread is transferred onto the web in a curved configuration.
  • the apparatus according to the invention for applying contoured thread sections or complete tear-open threads has a contoured, that is to say curved, severing cutout by means of which in each operating cycle, during a momentary standstill of the web or of a web section, a tear-open thread which is shaped according to the invention is cut off from a transversely fed thread web and positioned precisely on the (film) web, to be precise in the region of a blank which is to be cut off from the latter.

  • FIG. 16 and FIG. 17 show a detail of the apparatus according to FIG. 14 with elements in different positions, in a vertical section corresponding to section plane XVI-XVI in FIG. 14 .
  • the drawings shows cigarette packs as the preferred application cases, to be precise a hinge-lid box 10 (hinge-lid pack) and a multipack for cigarette packs, namely a cigarette multipack 11 ( FIG. 11 ).
  • the abovementioned packs are rigid packs made of (thin) cardboard and are each enclosed by an outer wrapper.
  • the latter consists of a thin, transparent plastic film, in particular shrink films made of cellophane, although it may also consist of some other packaging material, for example paper.
  • a blank 12 , 13 for forming the outer wrapper comprises a front wall 14 , rear wall 15 and side walls 16 , 17 .
  • the blanks 12 , 13 also form end walls 18 and a base wall 19 (hinge-lid box 10 ).
  • the side wall 16 is positioned as a continuous material strip between the front wall 14 and rear wall 15
  • the opposite side wall 17 comprises an outer side flap 20 and an inner side flap 21 .
  • the two side flaps 20 , 21 overlap one another and are connected to one another by sealing or adhesive bonding.
  • the end wall 18 and base wall 19 comprise end flaps 22 , 23 which extend over the entire length of the blank 12 , 13 .
  • the resulting blank 12 , 13 in a first folding step, is folded in a U-shaped manner, as is known, around the pack, namely hinge-lid box 10 or cigarette multipack 11 .
  • the side flaps 20 , 21 which initially project beyond the pack, are folded one after the other, with partial overlapping ( FIGS. 1 and 11 ).
  • the end flaps 22 , 23 are then folded in order to form the end wall 18 and the base wall 19 , respectively.
  • a tear-open thread 24 is fitted on the pack or on the outer wrapper thereof.
  • the possibly strip-like tear-open thread 24 is connected, preferably to the inside of the blank 12 , 13 , by adhesive bonding or sealing.
  • a grip tab 25 Integrally formed at one end of the open-ended tear-open thread 24 is a grip tab 25 which is formed from the blank 12 , 13 and, when the pack is complete, extends at the border of the side wall 17 or the side flap 20 and can thus be gripped by hand. With the aid of this grip tab 25 , the tear-open thread 24 can be drawn off, the outer wrapper or the blank 12 , 13 being severed in the process.
  • the tear-open thread 24 is fitted on the blank 12 , 13 in a particular configuration, such that the outer wrapper is severed essentially diagonally in the region of the large-surface-area pack sides by the cut-off tear-open thread 24 . This allows corner caps of the outer wrapper which are formed to be easily drawn off diagonally.
  • the (single-piece) tear-open thread 24 is positioned on the blank 12 , 13 such that, in the region of the front wall 14 , on the one hand, and of the rear wall 15 , on the other hand, it follows a more or less diagonal course (in a common imaginary diagonal plane). Accordingly, thread sections 26 , 27 extend approximately from one bottom pack corner 28 to the diagonally opposite pack corner 29 . In the case of the actual example, the thread section 26 , 27 runs at a small distance in each case from the relevant pack corner 28 , 29 , and thus from the base 19 , on the one hand, and the end wall 18 , on the other hand.
  • the tear-open thread forms a rounded portion 30 as a transition into transversely directed, rectilinear thread sections 31 , 32 .

  • This thread section 32 comprises two partially overlapping sub-sections. Accordingly, the tear-open thread is arranged such that its ends overlap.
  • a grip tab 25 is provided on the segment of the thread section 32 .
  • One special feature is the production of the blanks 12 , 13 from a continuous web 33 , from which blanks 12 , 13 are cut off along a severing cut 68 in a blank subassembly 34 of the packaging machine ( FIG. 3 ).
  • the tear-open thread 24 is applied to the continuous web 33 , preferably with continuous conveying movement.
  • the likewise continuously fed tear-open thread 24 is guided, and positioned on the web 33 , so as to achieve a more or less meandering or undulating configuration of the tear-open thread 24 ( FIG. 2 ).
  • the resulting thread sections 31 , 32 which run in the longitudinal direction of the web 33 , are of different lengths.
  • the thread section 32 which is directed toward the end wall 18 , is longer than the thread section 31 in the region of the side wall 16 .
  • the operation of applying the tear-open thread 24 to the continuous web 33 involves a process-related and equipment-related special feature.
  • the tear-open thread 24 is transferred to the web 33 by a guide element, in the present case by a rotating guide roller 35 , the latter being fitted on a mount.

  • An apparatus for applying the tear-open thread 24 to the web 33 is expediently a constituent part of the packaging machine ( FIG. 3 ).
  • the subassembly is indicated as detail IV. Accordingly, the web 33 , which is drawn off from reels 38 , is fed to a thread unit 39 . This is shown, by way of example, in FIG. 4 .
  • the tear-open thread 24 is drawn off from a thread reel 40 .
  • the tear-open thread 24 is expediently provided with adhesive on one side, namely on the side which is directed toward the web 33 .

  • the tear-open thread is guided over compensating rollers 41 , which can be moved relative to one another and bring about conveying compensation to the tear-open thread 24 during start-up and stoppage of the packaging machine, that is to say in operating situations which differ from the standard operating procedure.
  • the actual thread subassembly comprises two gear units 42 , 43 .
  • the gear unit 42 serves for compensating for -the conveying speed of the tear-open thread 24 on account of the relative movement between the web 33 and tear-open thread 24 .
