Definitions

  • This invention addresses the technical field of containers for pourable food products. More in detail, the invention relates to a method for the production, without waste, of non-parallelepiped shaped containers for pourable products from a single continuous web of packaging material, and to a container obtained with this method.
  • containers for pourable food products obtained from a single continuous web of packaging material. These containers are generally used to contain milk, fruit juices, sauces or beverages of other kinds.
  • the web of packaging material from which the containers are formed are composed of a plurality of layers of different materials coupled to each other (generally paper, aluminium, and heat-sealable plastic material such as polyethylene, for example).
  • the web of packaging material is processed in a dedicated automatic machine which comprises, in cascade, different stations through which the web is conveyed until single, filled and sealed containers are obtained.
  • Containers obtained from a continuous web of material generally have the shape of a parallelepiped. Containers having this shape, however, may be unergonomic for consumers and/or may not guarantee optimum pourability of the product from the container itself.
  • Containers with shapes different from parallelepipeds are, instead, usually obtained from corresponding blanks which are individually folded, filled and sealed, and are thus not obtained from a continuous web of material.
  • making containers of a shape other than parallelepiped from a web of packaging material involves creating waste material, even in significant amounts, with all the costs associated therewith.
  • This invention has for an aim to overcome the drawbacks described above.
  • This aim is achieved by proposing a method for the production, without waste, of non-parallelepiped shaped containers for pourable products from a single continuous web of packaging material, and to a container obtained with this method, according to the accompanying claims.
  • this invention allows using a continuous web of packaging material for producing containers for pourable products, without waste, where such containers are ergonomic and have a shape different from the shape of a parallelepiped.
  • the container 1 comprises: two side walls 4, 40, opposite to each other and transverse to the top wall 3 and the bottom wall 2; a front wall 5 and a rear wall 50 disposed between the two side walls 4, 40 and connected to the side walls by means of corresponding perimetral edges 54, 540.
  • the container 1 also comprises two side seals 6 (only one of which is shown in the drawings), each positioned at a corresponding side wall 4, 40.
  • the container 1 has, on each side wall 4, 40, two first fold lines S (only one of which is shown in Figures 1 and 2 ).
  • the first two fold lines S are formed when the side seals 6 are made by the sealers usually present in dedicated automatic machines.
  • the first fold line S illustrated is located at the centre line of the corresponding side wall 4.
  • the front wall 5 and the rear wall 50 each have, in particular, a trapezoidal shape.
  • the perimetral edges 54, 540 are inclined with respect to the axis of extension H of the container 1.
  • side seals 6 are inclined with respect to the perimetral edges 54, 540 (and also with respect to the axis of extension H).
  • the top wall 3 and the bottom wall 2 of the container 1 clearly differ in size.
  • the top wall 3 is smaller than the bottom wall 2, that is to say, the minor bases of the trapeziums of the front wall 5 and rear wall 50 are connected to the top wall 3, while the major bases of the trapeziums of the front wall 5 and rear wall 50 are connected to the bottom wall 2 of the container 1.
  • This preferred embodiment facilitates dispensing of the product, which is conveyed towards the part of the container 1 with the smaller cross section, that is, the top wall 3, where suitable dispensing means 30 are provided to allow pouring the product out.
  • the container 1 On its top wall 3, the container 1 has a second fold line P created by the process by which the container 1 itself is formed, as will become clearer in the description of the method which follows.
  • the top wall 3 and the bottom wall 2 of the container are both rectangular in shape.
  • the top wall 3 is square and the bottom wall 2 is rectangular (as in the case illustrated in the drawings).
  • top wall 3 and the bottom wall 2 of the container 1 are both trapezoidal in shape.
  • top wall 3 is trapezoidal in shape and the bottom wall 2 is rectangular, or vice versa.
  • the side seals 6 on the side walls 4, 40 of the container 1 do not run along the centre line of the corresponding side wall 4, 40 but, instead, are proximal to one of the perimetral edges 54, 540.
  • this aspect increases the size of the printable surface of the side walls 4, 40 compared to prior art containers in which the side seals are located centrally of the side walls of the containers.
  • the method according to the invention used to make a container 1 like the one described above, comprises providing a continuous web N of packaging material extending mainly longitudinally and comprising (with reference in particular to Figure 3 ): two longitudinal edges B1, B2 parallel to each other, and a plurality of zones Z1, Z2 adjacent to each other and consecutive along the extension of the web N.
  • the zones Z1, Z2 are perpendicular to the longitudinal edges B1, B2 and each is intended to form a container 1. That means each zone Z1, Z2 defines the length of web N used to form one container 1.
  • the web N is, for example, unwound from a roll B, as shown by way of an example in Figure 3 .
  • the method comprises the step of making first longitudinal and transverse crease lines 8 and 7 on the web N, in order to define, in each zone Z1, Z2, at least: a first portion 70 intended to form the rear wall 50 of the container 1 (once formed), a second portion 80 intended to form the front wall 5 of the container 1 (once formed); and a third portion 90, interposed between the first portion 70 and the second portion 80, intended to form the top wall 3 of the container 1 (once formed).
  • the step of making the first crease lines may be carried out before the web N is fed to the machine or after the web N is fed to the machine.
  • the step of making the first crease lines may or may or may not be carried out by the same automatic machine which makes the containers 1.
  • the method further comprises the step of folding the web N on itself (specifically at the third portion of each zone Z1, Z2, that is, along the axis of extension of the web N), closing it (by sealing) in such a way as to form a continuous tube I that is open at one end (see Figure 4 ).
  • the step of folding the web N makes, on the formed containers 1, a second fold line P running along the top wall 3 (see Figure 1 ), specifically along the centre line of the top wall 3. For greater clarity, the second fold line P is also shown in Figure 4 .
  • the continuous tube I is filled with a pourable product (milk, fruit juice, etc.) and then sealed in such a way as to form closed and filled packages (not illustrated) adjacent to each other (and each coinciding with a zone Z1, Z2 of the web N).
  • a pourable product milk, fruit juice, etc.
  • Figure 4 schematically illustrates, by way of example, a filler pipe F used to fill the continuous tube I with the pourable product.
  • the packages, once filled and closed, are then separated by cutting the continuous tube I perpendicularly to the longitudinal edges B1, B2 of the web N.
  • the cut by which each package is separated from the continuous tube I is made substantially half way along the sealed part so that a single seal closes two packages.
  • the web N is cut at the edges which delimit each zone Z1, Z2 from an adjacent zone Z1, Z2.
  • the cutting lines T of the tube I coincide with the separating lines of the zones Z1, Z2 of the web N (see Figure 4 ).
  • each container 1 is defined by folding each package at the first transverse and longitudinal crease lines 7 and 8 previously made on the web N of packaging material.
  • first transverse and longitudinal crease lines 7 and 8 on the web N are made in such a way that the first portion 70 and the second portion 80 of each zone Z1, Z2 have a trapezoidal shape.
  • the first transverse and longitudinal crease lines 7 and 8 define two trapezoidal shapes bilaterally with respect to the axis of extension of the web N.
  • the two respective non-parallel sides, which are inclined and convergent, will constitute the aforementioned perimetral edges 54, 540 (described above) of the container 1 when formed.
  • the transverse and longitudinal crease lines 7 and 8 on the web N are made in such a way that the first portion 70 and the second portion 80 of each zone Z1, Z2 have a trapezoidal shape, the perimetral edges 54, 540 of the container 1 obtained (that is, the side edges, that is, the transverse crease lines 7 themselves) will be inclined with respect to the line of cutting the web N and with respect to the side seals 6.
  • containers 1 which are not in the shape of parallelepipeds and which are thus ergonomic are made without producing any waste material. This is guaranteed by the fact that the cut is not shaped to make seals which are parallel to the perimetral edges of the container but is made perpendicularly to the longitudinal edges B1, B2 of the web N.
  • second transverse and longitudinal crease lines 11 and 10 can be made on the web N (see detail of Figure 5 ).
  • Some of the second crease lines 11, for example, are such as to define in each portion Z1, Z2 of the web N, side portions 400 adjacent to the first portion 70 and the second portion 80 along the direction of extension of the web N; again with reference to the drawings, the second transverse crease lines 11 are parallel to the first transverse crease lines 7.
  • the side portions 400 thus defined can be intended to constitute the side walls 4, 40 of the container 1, once formed (see detail of Figure 5 ).
  • the second longitudinal crease lines 10 can define the fold lines for what will become the corners Z of the container 1.
  • each corner of the individual "pillow" package is folded (for example, along the aforesaid second longitudinal crease lines 11) and sealed along one wall of the container 1 being formed. More in detail, two corners (not illustrated in the accompanying drawings) are folded and sealed for example on the bottom wall 2 of the container 1 and the other two corners Z (only one of which is shown in Figures 1 and 2 ) are folded and sealed along the side walls 4, 40 of the container 1.
  • the first transverse and longitudinal crease lines 7, 8 of each zone Z1, Z2 of the web N are shaped in such a way that once the corners of the corresponding package have been folded onto the side walls 4, 40 of the container 1, they do not protrude beyond the perimetral edges 5, 540.
  • the inclination of the crease lines (hence of the perimetral edges) of the trapezoidal shapes is thus limited by this aspect.
