Definitions

  • the present invention regards a method for producing containers filled with a product and sealed starting from a web of packaging material, the method comprising the steps of:
  • a fundamental aspect of a method of the type referred to above consists in guaranteeing that the inside of the tube formed during the process, into which the product to be packaged is directly dispensed, will be protected from any external contamination that might in fact jeopardize the quality of the product itself.
  • the aforesaid tube obtained with the web of packaging material, is formed within a controlled-pressure sterile environment.
  • the single semi-finished containers are, instead, obtained in a chamber in contact with the external environment, set downstream of the aseptic chamber, using a welding, forming, and cutting unit.
  • the liquid lubricant sprayed onto the outer surface of the tube which has the function of favouring proper operation of the aforesaid welding, forming, and cutting unit, is applied on the tube in the above chamber downstream of the aseptic chamber, precisely to prevent contamination of the inside of the tube with the liquid lubricant.
  • a gasket element is also set at the outlet section that sets the two chambers in communication and is traversed by the tube formed and filled with product, precisely to avert entry of contaminants into the aseptic chamber.
  • the present applicant initially thought of solving the above technical problem both by testing more vigorous processes of cleaning and sterilization of the production machine and by increasing the frequency with which this type of processes are performed in the machine.
  • the present applicant discovered that the liquid lubricant, when sprayed onto the outer surface of the tube, is able to infiltrate in the form of droplets in suspension into the aseptic chamber in which formation of the tube takes place.
  • the present applicant was able to note that, by way of the oscillation of the walls of the tube generated by the operations of sealing and cutting of the tube itself, there is brought about a sort of pumping action on the part of the tube itself. This pumping action creates a retrograde movement of the droplets of liquid lubricant from the chamber in which the sealing and cutting unit operates to the aseptic chamber.
  • a first position is said to be "upstream” of a second position when the first position precedes the second position with reference to the direction of feed of the object; vice versa, the second position is said to be “downstream” of the first position in so far as it follows the first position once again with reference to the direction of feed of the object.
  • the present invention regards a method for producing containers filled with a product and sealed starting from a web of packaging material.
  • the method comprises the step of moving said web of packaging material along a work path.
  • the method comprises the step of folding said web about a main axis parallel to said work path, in particular so as to form a tube.
  • the method comprises the step of welding together opposite edges of said web, in particular so as to seal longitudinally said formed tube; said opposite edges are preferably parallel to the main axis.
  • the method comprises the step of filling said formed tube with said product.
  • the method envisages the step of subjecting a liquid lubricant to a sanitizing operation.
  • said sanitizing operation includes the step of introducing into said liquid lubricant a sterilizing substance.
  • said sanitizing operation includes the step of subjecting said liquid lubricant to a filtering operation using a filter with antipathogenic action.
  • said sanitizing operation includes the steps of introducing into said liquid lubricant a sterilizing substance and subjecting said liquid lubricant to a filtering operation using a filter with antipathogenic action.
  • the method envisages the step of spraying the sanitized liquid lubricant onto an outer surface of said formed and sealed tube.
  • the method envisages the step of obtaining, starting from said formed and sealed tube, single semi-finished containers filled with said product.
