Definitions

  • the prior art describes a package for food products cut into thin slices, for example ham, salami etc., which package is constituted by a rectangular envelope formed by two sheets of alimentary-use plastic material, one superposed on another and welded along the perimeter thereof.
  • the external surface of one of the sheets of plastic material is completely covered by a sheet of paper material.
  • the main aim of the present invention is to obviate the above-described drawbacks by providing a package having the characteristics of one or more of the appended claims.
  • the set aim is achieved by a package having technical characteristics which are included in the accompanying claims, and the advantages of the package will more clearly emerge from the detailed description that follows, made with reference to the accompanying figures of the drawings, included by way of non-limiting example, which illustrate a preferred embodiment of the invention, and in which:
  • 1 denotes in its entirety a package for food products 2 cut into thin slices, for example ham, salami etc.
  • Figure 2 shows that the package 1 is obtained from two rectangular sheets, a first sheet 3 and a second 4, which are identical and are made of transparent and heat-weldable material (polypropylene).
  • the first and second sheets 3 and 4 are superposed one on another and on the surface of the second sheet 4 opposite the face thereof facing the first sheet 3 two paper strips (see also figure 3) are applied, parallel to the longitudinal sides 5.
  • D denotes the width of the two strips 7 which cover the two lateral portions of the sheet 4 and define between them a central aperture 8 having a width denoted by T.
  • Figure 3 in particular illustrates how between the first and second sheets 3 and 4 slices 9 of a product 2 are inserted, preferably in a controlled environment, and by a welding operation of the first and second sheets 3 and 4 along the longitudinal sides 5 and 6 an envelope 10 is produced, closed on a first side by the first sheet 3 of plastic material and closed on a second side by the second sheet 4 of plastic material provided with the paper cover constituted by the two strips.
  • the package 1 of figure 1 is obtained from the envelope 10 by wrapping the envelope 10 about an axis A which is transversal to the longitudinal sides 5, in order to realise a roll 11 having a curved external surface which is defined by the second sheet 4 provided with the two sheets.
  • the package of figure 4, denoted by 12, is different from the first package 1 only inasmuch as it is obtained by rolling an envelope 13, illustrated in figure 5 and absolutely equivalent to the other envelope 10, about an axis B which is parallel to the longitudinal sides 5.
  • the inspection opening 8 exhibits a width denoted by T1 which is less than the width T of the first package 1.
  • the package of figure 6, denoted by 14, is different to the first package 1 and the second package 12 because the two covering strips 7 of the second sheet 4 are replaced by a paper sheet 15 having at least an inspection opening 16.
  • the openings can be shaped in any way.
  • the rolls 11 of the package 1, 12 and 14 are closed by means for fixing constituted for example by adhesive labels 17.
  • 18 denotes in its entirety a unit for realising, for example, the package 1, and in particular it denotes lengths of plastic destined to form the first sheet 3 and the second sheet 4, partially covered by the strips 7.
  • a paper sheet 20 having a width 4D (i.e. four times the width of each strip 7) unwinds from a roll 21 and is subdivided by a pair of rotary cutters 22 working together with a guide roller 23, into three strips, denoted from left to right by 24, 25 and 26, of relative dimensions D, 2D, D.
  • the two lateral strips 24 and 26 are transversally deviated with respect to axes thereof by dividers of known type, for example constituted by two rollers 28 having inclined axes, in order to distance from one another by a predetermined distance T, which is equal to the width of the inspection opening 8.
  • the welding rollers 32, 33 send on the resulting band 34 to subsequent work stations which include a pair of rotary cutters 35 arranged above and below of the band 34, which cut the band 34 longitudinally into two equal bands 36 and 37, each half the size of the cut band 34.
  • the two bands 36 and 37 are then switched towards two known-type winders, denoted by 38 and 39 and are wound onto respective reels 40 and 41.
  • the reels 40 and 41 are used in a packaging machine, which uses the lengths defining the sheets 4 complete with the paper strips 7, made by performing a transversal cut across the two bands 36 and 37, for realising the envelopes 10 and thereafter the rolls 11 constituting the packages.
  • the envelopes 13 from which the packages 12 are made are obtained using the same operational modalities.
  • the type of roll 11 package is stiffer and more resistant than known packages, offering better protection for the sliced product.
