Definitions

  • suction tube bands Flexible bands with transversely applied suction tubes (hereinafter called “suction tube bands”) are used in the packaging industry to make possible the mechanical and automatic application of suction tubes to packing containers.
  • the suction tube band comprises suction tubes which are wrapped in individual protective envelopes adapted to the shape of the suction tube.
  • the protective envelopes in turn are joined to one another so that a band of coherent, wrapped, suction tubes is formed.
  • the wrapped suction tubes arranged transversely in relation to the band are evenly spaced.
  • the protective envelopes may be in the form of separate sleeves, which are joined to one another by means of narrow bands or strips of paper or plastics, but they may also constitute integrated parts of the flexible band.
  • a suction tube band thus may comprise two webs of plastic material between which the suction tubes are placed. The webs are joined to one another at least in the zones surrounding the suction tubes and are held enclosed in individual, closed protective envelopes.
  • Suction tube bands of the type described above are used to make possible the mechanical and automatic application of individual suction tubes wrapped in the protective envelopes to packing containers e.g. for juice or other beverages which are intended to be drunk directly from the packing container with the help of suction tubes.
  • the suction tubes are fed to the machine in the form of the said suction tube band, whereupon the machine separates one wrapped suction tube at a time from the band and transfers and applies it to a packing container passing through the machine.
  • a machine of this type is described e.g. in SE-A-780 10 67-5.
  • the suction tube band is in the form of two plastic webs sealed to one another, between which are enclosed the suction tubes, certain difficulties arise sometimes for the application machine or the applicator in separating the individual, wrapped suction tubes from the suction tube band. These difficulties are associated with the fact that the demand for accurate and exact cutting off of the individual protective sleeves is difficult to combine with the high operating speed of the applicator.
  • the plastic material of which the suction tube band is made is comparatively tough and difficult to break up, causing the material to stretch, so that the severing is rendered more difficult and the cut will be incomplete or end up in an incorrect position, which involves the risk of the protective envelope being broken, so that it can no longer fulfil its object of protecting the wrapped suction tube from contaminations.
  • a packaging comprising a flexible band of the kind referred which is provided with further transverse cuts extending from the longitudinal edges of the band and also between adjacent suction tubes which further transverse cuts are terminated by further cuts which in the longitudinal direction of the band are also of a many times greater extent than the width of these further transverse cuts.
  • inventive packaging could preferably be further provided with the feature of the subsidiary claim 2.
  • inventive packaging could preferably be further provided with the feature of the subsidiary claim 2.
  • further cuts with either a circular or a triangular form it thereby will additionally be secured that no unintentional widening of these further cuts takes place during the handling of the inventive packaging in an applicator of the kind as described in SE-A-780 10 67-5.
  • the suction tube band as shown in fig. 1 comprises a band 1 which consists of two webs of thermoplastic material of equal width placed against each other.
  • the suction tube band I comprises moreover suction tubes 2 which are placed between the said thermoplastic material webs and are wholly enclosed by the same.
  • the suction tubes 2 are placed transversely in relation to the band 1, that is to say substantially at right angles to the longitudinal edges 3 and 4 of the band 1.
  • the two webs forming the band 1 are of a width which somewhat exceeds the length of the suction tubes 2, thus making it possible to seal the two webs to one another in a zone (which is indicated as a hatched area in figure 1, corresponding zones existing also in the other embodiments shown, but having been left out in figures 2-5, so as not to impair the clarity of the figures) which wholly encloses each individual suction tube 2, so that each suction tube 2 is enclosed in an airtight suction tube envelope 5.
  • a zone which is indicated as a hatched area in figure 1, corresponding zones existing also in the other embodiments shown, but having been left out in figures 2-5, so as not to impair the clarity of the figures
  • the suction tube band is further provided between each individual suction tube with a transverse cut 6, which linearly cuts through the two webs forming the band 1 in the sealed region between the individual, airtight suction tube envelopes 5.
  • the cut 6 extends transversely over the suction tube band 1 but terminates at some distances inside the two longitudinal edges 3, 4 of the band 1, so that two strips or bridges 7 are formed in the band material which strips or bridges hold together the individual suction tube envelopes to a coherent band.
  • the two strips 7 extend at a distance from one another parallel along the longitudinal edges 3, 4, of the suction tube band, thus ensuring that the individual suction tube envelopes 5 maintain their correct position in the suction tube band so that the latter obtains a rope-ladderlike form.
  • cuts 6, which are produced with the help of heated knives in connection with the heat-sealing of the two webs to one another, facilitates appreciably the subsequent separation of the individual suction tube envelopes 5 from the suction tube band in the applicator.
  • a cutting through or punching through of the relatively narrow strips or bridges 7 is required which remain between end points of the cut 6 and the two longitudinal edges 3, 4 of the suction tube band.
  • This cutting through can be carried out relatively simply compared with a cutting over the whole width of the band.
  • the suction tube band is also provided with further cuts 8 which, like the cuts 6, are brought about with the help of heated cutting elements in connection with the manufacture of the suction tube band, and are placed at the positions at some distance inside the two longitudinal edges 3, 4 of the suction tube band where the end points of the cuts 6 are situated.
  • Each cut 6 thus meets at some distance inside the longitudinal edges of the band at both its ends cuts 8 which seen in longitudinal direction of the band 1 take up a many times greater extent than the said transverse cut 6, whose main direction is in fact transversely in relation to the band 1.
  • the width of the cuts 6 is negligible and merely corresponds to the necessary thickness of the heated knife by means of which they are produced.
  • the cuts 8 are linear and extend substantially at right angles to the cuts 6, that is to say, the cuts 8 extend in the longitudinal direction of the suction tube band 1.
  • the length of the cuts 8 determines the tolerance which can be allowed in the placing of the separating cut through the strips 7, and the cuts 8 are made therefore as long as is possible without any risk of their reaching or negatively influencing the unsealed region of the suction tube band 1 which forms the airtight suction tube envelope 5.
  • each cut 6 may also end in accordance with a sub- feature of the present invention in circular holes 9 which serve as a "hollow recess" to prevent that on stressing of the suction tube band the cut 6 is unintentionally widened or extended to the edge of the suction tube band.
  • the hole 9 is obtained in the same manner as the linear cuts 8 described earlier, at the same time as when the cut 6 is produced with the help of a heated knife or punching element, during the manufacture of the suction tube band.
  • waste material is produced which must be taken care of so as not to affect the manufacturing process by acting as an obstacle and diminishing the rate of production.
  • endside “hollow recesses” may instead also be provided, as shown in figure 3, with a substantially triangular form.
  • a triangular hole 10 has the advantage over the circular hole 9 that it has a distinctly limited area which makes it possible to produce the hole by melting off the thermoplastic material in connection with the production of the cut 6. Consequently the handling and taking care of waste material during the manufacture of the suction tube band can be avoided.
  • each hole 9 or 10 seen in longitudinal direction of the band 1, has to be greater than the corresponding width of the cut 6, so that the placing of the supplementary cuts, in connection with the separation of the individual suction tube envelopes from the band, is facilitated.
  • the shape of the hole is such that the hole serves as a recess at the end of the cutting line.
  • a hole of approx. 5 mm diameter has been found to be satisfactory and appreciably increases the area within which the supplementary cuts can be placed, since normally the width of the main cut will be less than 1 mm.
  • the distance between two suction tubes located next to each other is typically 15 mm.
  • the cuts 8' may also enclose removed portions of the band, so that the cuts substantially obtain the form of circular holes 9'. This will secure the same advantages as described above with respect to the holes 9 and 10 provided at the ends of the cut 6.
  • a suction tube band is provided which, in spite of being easy to handle and extremely simple, can be broken up into individual suction tube envelopes with the help of a suction tube applicator of known type.
  • the division into individual suction tube envelopes may be done at great speed without safety being endangered, and, owing to the special design of the suction tube band, moreover, optimum operational safety is achieved, even if the position of the band, owing to its flexibility, varies within wide limits of the instant of severance.
