Definitions

  • the present invention relates to a tubular pillow pack, particularly for food products.
  • substantially parallelepiped products in particular are wrapped in so-called tubular "pillow" packs formed from a continuous strip, one surface of which, contacting the product and hereinafter referred to as the “inner surface”, presents two peripheral longitudinal portions and a succession of cross bands coated with cold-stick adhesive material.
  • these are normally loaded successively on to the inner surface of the strip, in the space defined by each two adjacent cross bands; and the strip is folded transversely so as to overlap the adhesive peripheral longitudinal portions, which are pressed together to define a continuous tubular wrapping with a lateral tab consisting of the joined opposite longitudinal edges of the strip.
  • the continuous wrapping is then cut along the center line of each cross band to produce a succession of fluidtight tubular pillow packs, each containing one product.
  • the inner surface of the continuous strip presents a further cross band of cold-stick adhesive material to which is applied a first surface of a ripoff tape, one end portion of which extends across one of the peripheral longitudinal portions of the strip.
  • a second surface of the ripoff tape, opposite the first surface is coated, at least on said end portion of the tape, with a layer of cold-stick adhesive material.
  • the ripoff tapes are formed by transversely cutting a continuous tape wound off a reel and one surface of which presents a longitudinal lateral portion coated with cold-stick adhesive material. On the reel, the adhesive lateral portion must be protected by a nonstick backing tape, which, as the reel is unwound, must be eliminated and wound on to an auxiliary takeup reel.
  • a tubular pillow pack particularly for food products, comprising a portion of a first sheet having an inner surface contacting the product, two longitudinal edges and two transverse edges, a first layer of cold-stick adhesive material on a portion of said inner surface extending along each of said edges, and a ripoff tape integral with said inner surface and perpendicular to said longitudinal edges; said sheet being folded so as to mate both the two inner surface portions along the longitudinal edges, with the interposition of an end portion of said tape, and the two inner surface portions along the transverse edges; characterized by the fact that the tape is heat-sealed integral with said inner surface; and the tape is formed from a second sheet having a first surface contacting said inner surface and coated with a layer of non-cold-stick material, and a second surface, opposite said first surface, coated with a second layer of cold-stick material, at least on a lateral portion corresponding with said end portion of said tape.
  • Said nonstick material preferably consists of lacquer applied to at least a portion of said first surface corresponding with the end portion of said tape.
  • Number 1 in Fig.1 indicates a tubular pillow pack or wrapping for a product 2 (Fig.s 2 and 3), in particular, a substantially parallelepiped food product.
  • wrapping 1 is formed from a flat rectangular sheet 3 produced by transversely cutting a continuous strip 4, and having an inner surface 5 (Fig.3) contacting product 2 and defined by two longitudinal edges 6 and two transverse edges 7. Portions 8 and 9 of inner surface 5 extending respectively along edges 6 and 7 are coated with respective layers 10 and 11 of cold-stick adhesive material.
  • Wrapping 1 is formed by folding sheet 3 about product 2 so as to join the two portions 8 with respective adhesive layers 10 and so form a tab 12 (Fig.1) extending longitudinally outwards of wrapping 1 and which is folded on to the outer surface of sheet 3; and by joining facing transverse portions 9 with respective adhesive layers 11 so as to form two transverse tabs 13.
  • sheet 3 forms part of a continuous strip 4
  • layers 11 are joined for forming tabs 13 in known manner at the same time as strip 4 is cut transversely.
  • wrapping 1 also comprises a ripoff tape 14 extending along an intermediate portion 15 of inner surface 5 of sheet 3 and perpendicular to longitudinal edges 6.
  • the length of tape 14 is at least equal to the distance between the inner edge of one of longitudinal portions 8 and the opposite longitudinal edge 6, and is so arranged as to extend across one of longitudinal portions 8 and to be gripped between portions 8 during the formation of tab 12.
  • tape 14 presents a first inner surface 16 contacting portion 15 of inner surface 5 of sheet 3, and which is heat-sealed in place before product 2 is loaded on to inner surface 5.
  • tape 14 also presents an outer second surface 17 coated at least partially with a layer 18 of cold-stick adhesive material. More specifically, layer 18 is applied, as in the example shown, to the portion of surface 17 extending along end portion 19 of tape 14 over one of portions 8.
  • tapes 14 are formed by a cutting device 20 transversely cutting a strip 21 wound off a reel 22 and having a surface 23 corresponding with outer surface 17 of tapes 14 and which is coated, at least along a longitudinal lateral portion 24, with a continuous layer 25 of adhesive material corresponding with layer 18.
  • strip 21 also presents a surface 26 coated, at least along a lateral portion corresponding with end portion 19 of tapes 14, with a layer 27 of non-cold-stick material preferably consisting of lacquer.
  • the non-cold-stick material of layer 27 in no way prevents tapes 14 from being heat-sealed to sheets 3, during which process, in fact, it is converted, as in the Fig.3 example, into a layer 28 of adhesive material between surface 16 of tape 14 and inner surface 5 of sheet 3, or, according to a variation not shown, evaporates completely.
  • Wrapping 1 as described above may thus be produced with no recourse to heat-sealing in the presence of products 2, and provides for perfect fluidtight sealing as normally required by health standards governing the packing of food products.
  • strip 21 on reel 22 requires no backing strip for preventing adhesive layer 25 of one turn from adhering to surface 26 of the adjacent turn on reel 22.
