  • the spacer element 8 is inserted between the first film 103 and the second film 104 in such a way as to keep the films spaced from each other, so that the desired product can easily descend between the first film 103 and the second film 104 for being inserted into the package 100.
  • a dimension of the spacer element 8 measured transversely to a feed direction F1 of the films 103, 104, shown in Figure 5 is at its maximum.
  • a horizontal dimension of the spacer element 8 (more specifically, of its central portion 10 designed to be interposed between the films 103, 104) is at its maximum. This occurs because, in the configuration of maximum transversal dimension C1 , the spacer element 8 lies in a substantially horizontal plane.
  • the spacer element 8 is rotated relative to the configuration of maximum transversal dimension C1 , in such a way that its gripping dimension transversely to the feed direction F1 is at its minimum. More specifically, in the configuration of minimum transversal dimension, the spacer element 8 is positioned in such a way as to have minimum dimensions in a horizontal direction. This occurs because, in the configuration of minimum transversal dimension, the spacer element 8 lies in a substantially vertical plane.
  • the spacer element 8 is movable between the configuration of maximum transversal dimension C1 and the configuration of minimum transversal dimension thanks to a rotational movement about an axis of rotation R, shown in Figure 1 .

  • the rotation of the spacer element 8 about the axis of rotation R may be a rotation of 360° in a predetermined direction of rotation. In this way, the spacer element 8 can be positioned in a plurality of intermediate positions interposed between the configuration of maximum transversal dimension C1 and the configuration of minimum transversal dimension.
  • Figure 5 shows an intermediate configuration C2 which the spacer element 8 adopts during the rotation and which is close to the configuration of minimum transversal dimension.

This occurs both if the desired product is introduced into the package 100 by simply falling, due to the action of the force of gravity, and if nozzles are used to fill the package 100 with the desired product.
  • any contamination of the first film 103 and/or of the second film 104 above the package 100 which is about to be formed would be very unwanted especially if a package 100 must be filled with a product different from that with which the previous package 100 has been filled. In this case, if the product dripped onto portions of the films 103, 104 that will form the next package 100 while a package 100 is being filled, the package would be contaminated with a product different from the one that the package is intended to contain, which must be avoided.
  • the spacer element 8 which, at preset intervals, keeps the first film 103 and the second film 104 spaced apart, it is possible to avoid soiling the films with the substance introduced into a package 100 without excessively increasing the size of the packaging system 1 . That is to say, the spacer element 8 has a reduced size, which also makes the packaging system 1 which comprises the spacer element 8 compact. This is particularly appreciable if the packaging system 1 is designed to be used in a machine in which the available space is limited, as occurs if the packaging system 1 is intended to be used in an automatic dispenser.
  • the spacer element 8 is located above the cutting means 7 and the sealing means 13.
  • the packaging system 1 further comprises movement means 9 configured for moving the spacer element 8 between the configuration of maximum transversal dimension C1 , wherein the spacer element 8 guarantees good accessibility to the containment space 101 of the package 100 which is about to be formed, and the configuration of minimum transversal dimension, wherein the spacer element 8 allows the closing of the package 100.
  • the movement means 9 may be configured to rotate the spacer element 8 in a single direction of rotation about the axis of rotation R, positioning the spacer element 8 alternately in the configuration of maximum transversal dimension C1 and in the configuration of minimum transversal dimension.
  • the movement means 9 may comprise a set of levers 30, which may be connected to the linkage by which the first supporting part 21 and the second supporting part 22 are alternately moved close to each other or spaced apart. In this way, the same motor device allows both the first supporting part 21 and the second supporting part 22 to be moved relative to each other and to move the spacer element 8 between the configuration of maximum transversal dimension C1 and the configuration of minimum transversal dimension.
  • the packaging system 1 may comprise vacuum generating means 17 designed to remove air from the package 100 which is about to be formed and/or to create a negative pressure inside the package 100 relative to an outside environment.

  • the first sealing element 25 and the second sealing element 26 are activated so that the first sealing element 25 seals the portions of film 103, 104 clamped between the first floating element 14 and the second floating element 15 to join the films along a joining profile which defines a base and two sides of the package 100.
  • the second sealing element closes the package 100 already filled, positioned below the first supporting part 21 and the second supporting part 22.
  • first punching element 27 and the second punching element 28 protrude from the first floating element 14, for cutting the first film 103 and the second film 104.
  • first punching element 27 cuts the portions of film 103, 104 interposed between the first floating element 14 and the second floating element 15, immediately outside the joining profile made by the first sealing element 25.
  • the second punching element 28 acts on the package 100 already filled which has disengaged from the first floating element 14 and from the second floating element 15, performing a cut close to an upper edge of the package 100 and detaching it from the first film 103 and from the second film 104.
  • the suction element 18 has passed through both the first film 103 and through the second film 104 and both the films have been perforated, which does not have drawbacks because, as described above, the suction zone 31 is outside the package 100.
  • the first supporting part 21 and the second supporting part 22 are now moved away from each other, as shown in Figure 7, so that the first floating element 14 and the second floating element 15 also detach.
  • the package 100 already filled and closed, which is no longer connected in any way to the films 103, 104, falls downwards to be collected, for example, by a conveyor device not illustrated.
  • a new package 100 has already been formed, in which the films 103 and 104 have already been sealed to each other along the base and the two sides. The cut in the proximity of the base and of the two sides has also been performed. The new package 100 is open at the top and is ready to receive the product with which it must be filled.
  • the spacer element 8 returns again to the configuration of maximum transversal dimension C1 to allow the package 100 to be filled without contaminating the films 103, 104.
  • the packaging system 1 makes it possible to obtain packages 100 having dimensions which are variable depending on the type and quantity of product which must be introduced in each package 100.
  • Figure 9 shows the two films 103, 104 which have been sealed along a concave joining profile 36, which in the example shown comprises a base 32 and two sides 33.
  • the two films 103, 104 have also been joined along a closing line 34 which closes the concave joining profile 36 and is positioned above the base 32. If the closing line 34 is in the position shown in Figure 9, a package 100 of maximum dimensions is obtained. If the closure line is moved, for example, to the position 34' indicated with a dashed line in Figure 9, that is to say, downwards, a package 100 is obtained with smaller dimensions, designed to contain smaller quantities of a predetermined product.
  • the packaging system 1 is thus able to modify the dimensions of the package 100, even between the forming of one package and the next. This is particularly appreciated if the packaging system 1 is not used to produce packages 100 containing the same product always in the same quantity, but for producing packages 100 containing products which may vary between one package 100 and the next package 100, in terms of quantity or by type. Depending on the type and quantity of product selected each time, the packaging system 1 makes it possible to vary the size of the package 100. This further allows a saving in the polymeric material which forms the first film 103 and the second film 104, since - by adapting the dimensions of the package 100 to the quantity and type of packaged product - it is possible to reduce the waste of the above-mentioned polymeric material.
  • the package 100 may be provided with means for facilitating the opening by a user, such as pre-cut zones, tearing systems, gripping tabs, opening tapes and the like.
  • Figure 10 shows a package 100, filled with the product "A", after the package 100 has been opened. It should be noted that the package 100 remains standing autonomously after being opened. If the package 100 contains a food product, the user can consume the food product directly from the package 100 without transferring the food product to a plate or to another container. This is very convenient for the user, who can consume the food product wherever he/she is.
  • the packaging system 1 makes it possible to produce packages 100 in hygienic conditions, which are particularly important especially in the food sector.
  • the packaging system 1 allows the product to be enclosed in a package 100 which prevents contact with contaminating agents and can be consumed directly from the package 100, without being touched by the user.
  • the spacer element 8 which keeps the films 103, 104 spaced during filling, it is possible to avoid soiling the film destined to form successive packages 100 with the product placed in a package.
  • the packaging system 1 Since the packaging system 1 operates under particular cleaning conditions, it makes it possible to reduce the maintenance operations for the purpose of cleaning the packaging system 1 from accidental contamination.
  • the packaging system 1 has particularly compact dimensions, since the operations for sealing, cutting, filling and if necessary creating a negative pressure are carried out in a single station.
  • the invention increases the operating efficiency of the prior art packaging systems, overcoming the need for continuous cleaning cycles and eliminating the risk of contaminating the films used for successive packages.
  • the packaging system 1 is very simple in construction, thanks also to the presence of a limited number of actuator systems, in particular motors. This simplifies both the construction and the management of the packaging system 1 .
