Definitions

  • the present invention relates to a system for preserving sterile conditions in the filling spout area of containers, in plants for packaging in aseptic conditions.
  • containers consisting of large bags of plastic and/or metallized materials, laminated and/or in several layers, which are placed in special drums, or other suitable containers, for packaging products based on chopped tomatoes or tomato puree.
  • the wall of the bag generally comprises a barrier assembly with several outer layers and at least one inner polyethylene layer.
  • a spout that serves for subsequent filling of the bag
  • said spout protruding externally form the wall and being closed with a stopper, which can be a press-on stopper or a soft stopper or otherwise.
  • This stopper normally has a hollow in the external bottom wall, both for manufacturing reasons and to give it the elastic properties necessary to enable perfectly tight closure of the spout.
  • the bag thus prepared is normally subjected to gamma ray sterilisation to obtain complete sterilisation both of its inner surface and of its outer surface, including the spout and relative stopper.
  • the bags thus processed are then ready for use and are sent to the food packaging industries or food industries in general, who fill them with the relative product.
  • the product is subjected to particular heat treatments, to eliminate the bacterial content present in it and then sent to the filling plant, where a sterilised chamber is provided which is positioned so as to enclose the filling spout, first delivering a jet of steam to the outside of the spout , which should restore it to the sterile conditions which were obviously lost during the stages prior to filling, for example during introduction of the bags into the special drums or containers.
  • Appropriate means subsequently remove the stopper from the spout, keeping it inside the sterile filling chamber from which a tube is lowered and inserted into the spout to carry out filling of the bag with the product to be preserved.
  • spores or other micro-organisms may collect around the spout and pollute the filling chamber and consequently the product, damaging its quality.
  • the aim of the invention is to overcome the above drawbacks by providing an extremely simple and economical system for preserving and ensuring sterile conditions in the filling spout area of containers of the above type.
  • the aim is achieved, according to the invention, by providing an external cap to cover the spout and the relative stopper.
  • This cap is advantageously fitted before gamma ray sterilisation of the container, so that it itself is sterilised and preserves the sterility of the spout beneath it during storage and transportation of the container and in the stages immediately prior to filling.
  • This cap is removed immediately prior to filling of the container, thus ensuring the sterile condition of the spout at the moment of filling.
  • the cap can be made by thermoforming flexible or rigid plastic material, advantageously with an inner layer of polyethylene or polyester, and has for example an annular flange at its base, which is heat-sealed or glued to the area of the bag surrounding the spout.
  • the number 1 schematically indicates a portion of a container for aseptic packaging systems, consisting of a bag made of plastic material, with one or several layers, at least one of which may be metallized.
  • this wall of the container 1 is shown as a single laminate, comprising for example an intermediate metallized layer enclosed between polyethylene-based layers. It is clear, however, that other layered arrangements of materials are possible and that instead of a single laminate a plurality of films coupled together can be provided, for example a metallized outer film consisting of polyethylene, metallized polyester, polyethylene, and an inner film, possibly double, consisting of polyethylene.
  • the filling spout 2 is applied during production of the container 1, from the inside of the relative wall, in which a hole is made for it to pass, so that an annular base flange 3 of the spout remains inside the container and is welded to it by heat applied from the outside, for example by induction.
  • the spout 2 has a substantially tubular body, inside which a closing stopper 4 is inserted by pressure, said stopper normally having an inner hollow or recess 5.
  • the container 1, complete with the spout 2 and the closing stopper 4, as stated previously, is normally sterilised by gamma rays and them sent to aseptic packaging plant.
  • the invention provides for a protective hood or cap 6 to be applied to cover the spout 2 and the stopper 4, said cap having a base flange 7 and possibly a pull-tab 8.
  • the cap 6 is advantageously obtained by thermoforming of plastic material, comprising an inner layer of polyethylene, preferably of the so-called easy-open type.
  • plastic material comprising an inner layer of polyethylene, preferably of the so-called easy-open type.
  • the flange 7 can be heat-sealed to the outer surface of the relative wall of the container 1 and at the moment of filling the container the cap can easily be peeled away, an operation that is facilitated by the provision of the pull-tab 8.
  • the flange 7 can be fixed to the container 1 by different methods, for example by gluing.
  • the cap 6, as stated, is advantageously obtained by thermoforming of flexible or rigid plastic material, but it could also be made by moulding, although this method is more costly.
  • FIG 3 shows a different embodiment of the cap 6 which will now be described using the same reference numbers introduced in relation to Figures 1 and 2.
  • the stopper 4 in Figure 3 is made of relatively soft material and closes the upper outer edge of the spout 2 with a tight seal.
  • the cap 6 illustrated in Figure 3 is made of relatively rigid material and is shaped like a glass turned upside down, having an inner projection 9 which couples mechanically to an annular projection 10 provided around the spout 2.
