Definitions

  • the present invention relates to sealed wrappers (so-called “hermetic” wrappers) for foodstuffs, such as for example confectionery products.
  • the purpose of the present invention is to provide a wrapping capable of combining, with extreme structural simplicity, and consequently with extreme simplicity and economy of fabrication, excellent sealing qualities (hermetic sealing).
  • the solution according to the invention is characterized in that it gives rise to a wrapping that comprises a single sheet element closed by a single welding or sealing line.
  • a sealed wrapping for foodstuffs which comprises:
  • a sealing line which extends so as to close said wrapping sheet along a path that surrounds said at least one foodstuff product and has the ends located in a position corresponding to said bent part.
  • wrapping sheet is here understood to indicate any sheet material capable of isolating the product in an effective way from the external environment.
  • path which “surrounds” the foodstuff product is here understood to indicate a path which extends around the product (a path preferably having a generally arched, i.e., C-shaped pattern), usually privileging quite a tight relationship of wrapping, thus guaranteeing a wrapping of the product that is as adherent as possible, this being a result that can be favoured by possible actions of smoothing, brushing or other operations.
  • FIGS. 1 to 5 illustrate successive steps of a process designed to provide a wrapping according to the invention.
  • FIG. 6 is a side elevation of the corresponding plant.
  • the exemplary embodiment illustrated in what follows relates to the production of a wrapping for a foodstuff product 1 consisting, for example, of a confectionery product, such as a chocolate, a sweet, a praline, etc. of various shapes.
  • a foodstuff product 1 consisting, for example, of a confectionery product, such as a chocolate, a sweet, a praline, etc. of various shapes.
  • this may be a product provided with a coating, such as for example a coating of ground hazelnuts, grated coconut, grated meringues, etc.
  • the product 1 is designed to be wrapped in a wrapping constituted by a single sheet element 2 of a laminar wrapping material of the type widely used for the wrapping of confectionery products.
  • the material in question may be a “combined” material, i.e., a material which comprises at least one first layer, designed to constitute the outer part in the finished wrapping, and a second layer, designed to constitute the inner part in the finished wrapping, and which presents, for example, characteristics of heat-sealability.
  • a typical example of combined material of this nature is a material consisting of an outer foil made of aluminium coated on the internal surface with a plastic material, such as polyethylene.
  • the said individual element of wrapping may in fact be defined by a portion or length of a continuous sheet material, which is reeled off a reel and subjected to segmentation so as to form individual elements of wrapping.
  • the said product is represented in the form of a body having a parallelepipedal shape; however, it will be understood that the product 1 may be of any shape.
  • the element of sheet material 2 is wrapped around the product 1 so as to form:
  • a bent part 20 which in effect receives within it the product 1 ;
  • two lateral branches 21 which extend from the bent part 20 and are laid on the opposite faces of the product 1 (top and bottom faces in the orientation illustrated herein).
  • the sheet of wrapping is wrapped around the product 1 in such a way as to form a sort of pocket or envelope in which the lateral branches 21 conserve a substantially plane orientation, whatever the shape of the product 1 .
  • the two lateral branches 21 are substantially parallel to one another, separated by a distance substantially corresponding to the thickness or height of the product 1 .
  • the two lateral branches 21 are connected to one another by a sealing line 3 .
  • the sealing line 3 connects the two branches of the sheet of wrapping according to a path that surrounds the foodstuff product 1 . It is therefore in general a path having an overall arched, i.e., C-shaped pattern, with the ends located in a position corresponding to the bent part 20 , the said bent part evidently already performing an action of sealed reception of the product 1 , without any need to form lines of connection.
  • sealing line 3 In order to form the sealing line 3 it is possible to resort to a wide variety of techniques extensively adopted in the packaging industry, in particular for the packaging of foodstuffs.
  • the sealing line 3 may be made—for example—by means of hot-sealing, cold-sealing, sealing with or without weld material, ultrasound welding, laser welding or, possibly, by means of a mere action of embossing.
  • the wrapping presented in FIG. 4 may be completed by forming one or two fantail twist-wrapped parts 4 so as to bestow on the wrapping as a whole the typical appearance of a wrapping for sweets.
  • This result may be obtained (in a known way) by subjecting to twisting the longitudinal end or ends of the wrapping, or else resorting to other methodologies aimed at obtaining a fantail twist.
  • connection between the two branches 21 is therefore extremely intimate and continuous, and consequently such as to withstand, without weakening, any possible subsequent deformations of the wrapping.
  • the reference number 10 designates a unreeling assembly from which is reeled off the sheet material that is to constitute the wrapping 2 .
  • the sheet material 2 is fed towards a forming assembly 12 designed to bestow on the sheet material the general U-like shape comprising the bent part 20 and the lateral branches 21 (see FIG. 3).
  • the forming device 12 may be considered in itself as an element of a known type. It is in fact obtainable according to the criteria widely used for making forming devices which, in packaging machines of a flow-pack type, close the sheet material according to a general tubular pattern.
  • tubular wrapping formed in flow-pack machines is characterized typically in that it is closed by a longitudinal sealing line and in that it has a substantially circular cross-sectional profile
  • the corresponding intermediate piece obtained in the plant of FIG. 6 is instead open (see once again FIG. 3), in the sense that the two lateral branches 21 are not connected to one another in a position corresponding to their distal margins.
  • the intermediate piece represented by FIG. 3 presents a general U-shaped development, with the two lateral branches 21 maintained in a substantially flattened condition.
  • this fact is important for achieving a continuous and intimate connection, provided by means of the sealing line 3 , which lies at the base of the characteristics of sealing of the final wrapping.
  • Feed of the products 1 to be wrapped in the direction of the area where the forming device 12 operates is ensured by a conveyor 14 consisting, for example, of a motor-driven belt conveyor of the type widely used in plants for packaging foodstuffs.
  • the said conveyor 14 co-operates with the forming device 12 so as to cause the products 1 to be inserted in the wrapping material folded to form a U shape at regular distances apart, thus creating a loading station designated as a whole by 16 .
  • the closing station 18 may be of the type with vertical reciprocating movement and thus comprise a base or anvil part 18 a , as well as an active mobile element 18 b , which moves vertically and is lowered periodically onto the anvil part 18 a , thus creating the sealing line 3 and carrying out cutting of the individual wrappers.
  • the base part 18 a and/or the active element 18 b usually present surface indentations that define the path of the sealing line 3 .
  • the base part 18 a and/or the active element 18 b may have associated thereto heating elements and/or ultrasound generators (not specifically illustrated but of a known type) when the sealing technology adopted involves the application of heat and/or ultrasound.
  • the closing station 18 may be built so as to carry out, in addition to the vertical movement that leads the base part 18 a and the active element 18 b to close against one another with the interposition of the wrappers, also a movement of “tracking” of the advance of the wrappers.
  • the said tracking movement causes the action of formation of the sealing line 3 to come about in conditions of practically no relative movement.
  • the fixed anvil part 18 a may present a top surface that is at least slightly hollowed so as to ensure that the sealing line 3 (made with the wrapping comprised between the parts 18 a and 18 b closed against one another) will be obtainable in conditions of perfect symmetry.
  • the sealing unit 18 carries associated thereto cutting elements (not specifically illustrated, but of a known type) aimed at causing the continuous ribbon of sheet material 2 to be divided after or concomitantly with the formation of the sealing line 3 so as to give rise to individual wrappers, such as the wrapping designated by C in FIG. 6.
  • the reference number 20 designates a shaping station, in which one or both of the longitudinal ends of the wrapping C are subjected to a further treatment (for example twisting) so as to form the fantail parts 4 of FIG. 5.
  • one or more fantail parts 4 constitutes an optional and non-imperative step of the solution described herein.
