Definitions

  • the present invention concerns a container provided with a filling spout, particularly suitable for aseptic packaging systems, and a manufacturing method for such a container.
  • Containers of the above type consist of bags with walls of several-layers or films, with at least one metallized layer, or in any case with a barrier effect.
  • each wall of the bag has a metallized outer sheet, with the following system of layers, working from the outside inwards: polyethylene-metallized polyester-polyethylene, and a double inner sheet obtained from polyethylene tubing.
  • the bag will therefore have a total of six films: two outer laminates and two tubular inner films.
  • Such a bag is obtained by coupling the films of each wall separately and then heat-sealing them longitudinally along the edges and transversally to separate one bag from the next, after having inserted and fixed a filling spout into one wall of the bag.
  • composition of the walls of the bag can differ from that illustrated above by way of example, just as the manufacturing procedure for the bag, i.e. the different steps in coupling the films, can differ.
  • the filling spout which has a substantially tubular body, with an annular flange at the base, is inserted from the inside into the corresponding wall of the bag, before it is closed, making a hole which passes right through the entire wall.
  • the flange of the spout thus abuts against the inside of the corresponding wall of the bag and is heat sealed to it from the outside along a track with a circular outline.
  • the bag thus obtained in which the spout is closed by an outside cap, is normally subjected to gamma ray sterilization, before being sent to the users, in particular preserving or food industries in general, who use them for packaging tomato puree and chopped tomatoes, fruit juices and the like.
  • the bags are filled by means of special systems for aseptic packaging, in which the product, after having undergone heat treatment by means of tube nests, is sent to the loading head, comprising a sterilized chamber, which positions itself so as to enclose the spout, emits a jet of steam or suitable sterilizing solution so as to sterilize the spout area, removes the cap from the spout and lastly positions a product delivery tube inside the spout, so as to carry out filling of the bag.
  • a sterilized chamber which positions itself so as to enclose the spout, emits a jet of steam or suitable sterilizing solution so as to sterilize the spout area, removes the cap from the spout and lastly positions a product delivery tube inside the spout, so as to carry out filling of the bag.
  • the aim of the invention is to eliminate the above problems, while still guaranteeing the integrity of the inner chamber of the bag, and thus its state of sterility, both during and after application of the filler spout.
  • Another aim of the invention is to make application of the filler spout to the bag easier and safer.
  • the filler spout is applied to the corresponding wall of the bag, so that at least one inner layer of the bag remains intact until the time of filling. That is to say, the spout is applied from the outside on said layer or film of the wall of the bag, fixed for example by heat sealing to such a layer, and the other outer layers of the bag wall, pierced beforehand to allow the spout to pass through them, are subsequently coupled. Then follows a further outer seal around the spout, which is thus firmly fixed to the bag, with at least one inner unpierced film which is opened at the time the bag is filled by the stream of product sent into the bag under pressure, or by a preceding jet of steam, or by other means.
  • Figure 1 is a schematic cross section of a container according to the invention, taken in the area where the filling spout is applied.
  • Figure 2 is a schematic view of a manufacturing plant for the container according to the invention.
  • each wall of the container 1 comprises an outer laminate 2 which has, for example, a series of layers consisting, from the outside inwards, of polyethylene, metallized polyester, polyethylene and an inner polyethylene film 3.
  • a further layer of polyethylene can be provided between the outer laminate 2 and the inner film 3, according to per se known methods in the manufacture of containers for aseptic packaging systems, to which the invention refers.
  • Figure 1 shows a spout 4 fixed to the corresponding wall of the container 1.
  • the spout 4 comprises, in a per se known manner, an annular base flange 5 and a substantially tubular body 6, protruding from the wall of the container, which is sealed on the outside by a cap 7.
  • the spout is inserted by making a through hole in the corresponding wall of the container 1, which passes through both layers 2, 3, placing the flange 5 inside the container 1.
  • the spout 4 is applied from the outside, maintaining the film 3 intact, and heat sealing, gluing or fixing the base flange 5 in any other way to said film 3.
  • the outer laminate 2, previously pierced, is subsequently coupled to the film 3 to allow the passage of the tubular body 6 of the spout 4, and lastly a further seal is made at the annular flange 5, above the laminate 2.
  • the spout 4 is fixed extremely securely to the corresponding wall of the container 1, thanks to the double seal, without affecting the inner chamber of the container since at least the inner film 3 is maintained intact. In this way, the inner chamber of the container always remains completely separated from the outside environment, even if the seal of the cap 7 and the spout 4 were to be lost before the container 1 is filled.
  • the container 1 is brought beneath the filler head and the stream of product causes the polyethylene film 3 to break in order to free the access to the inner chamber of the container 1.
  • the layer of polyethylene 3 can be broken beforehand by a jet of pressurized steam.
  • the film 3 can be broken in advance by mechanical means, for example by the filler tube itself, which can be provided with a slantwise point with special teeth to cut the polyethylene film 3.
  • 10 indicates a reel from which tubing is unwound, comprising two polyethylene films 3-3 placed one on top of the other, that are to form the inner layers of the walls of the container 1.
  • the tubing 3-3 passes through a plurality of transmission rollers 11 that carry out per se known functions, and arrives at a station 12 where the spouts 4 are applied.
  • the spout 4 deliberately shown enlarged in Figure 2, possibly is applied in sterilized conditions to the outer surface of the upper film of the tubing, preferably by heat sealing its annular base flange 5. It is clear, however, that other fixing means can be provided, for example gluing or the like.
  • Means that are not shown can also be provided in the station 12 to keep the two films 3-3 of the tubing separate during application of the spout 4.
  • tubing 3-3 With the spout 4 applied advances and arrives at a station 13 where the outer laminate 2 is coupled to the wall bearing the spout 4.
  • the laminate 2 is unwound from a reel 20, passes through a plurality of idle rollers 21, is pierced at regular intervals at a punching station 14, so as to arrive at the coupling station 13 with a hole in perfect register with the spout 4 to allow it to be inserted, At this stage a further heat seal is made at the base flange 5 of the spout 4.
