Definitions

  • the present invention relates to an opening device, in particular to a reclosable opening device, configured to be applied to a package containing a pourable product, preferably a pourable food product.
  • pourable food products such as fruit juice, UHT (ultra-high temperature-treated) milk, wine, tomato sauce, etc.
  • UHT ultra-high temperature-treated milk
  • wine tomato sauce
  • etc. are sold in packages made of sterilized packaging material.
  • a typical example is the parallelepiped-shaped package for pourable food products known as Tetra Brik Aseptic (registered trademark), which is made by folding and sealing a laminated sheet of packaging material.
  • the packaging material has a multilayer structure substantially comprising a base layer for stiffness and strength, which may be made of fibrous material, e.g. paper or mineral-filled polypropylene material, and a number of lamination layers made of heat-seal plastic material, e.g. polyethylene films, covering both sides of the base layer.
  • a base layer for stiffness and strength which may be made of fibrous material, e.g. paper or mineral-filled polypropylene material, and a number of lamination layers made of heat-seal plastic material, e.g. polyethylene films, covering both sides of the base layer.
  • the packaging material also comprises a layer of gas-barrier material, e.g. aluminum foil or ethyl vinyl alcohol (EVOH) film, which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material.
  • gas-barrier material e.g. aluminum foil or ethyl vinyl alcohol (EVOH) film
  • EVOH ethyl vinyl alcohol
  • Packages of this sort are normally produced on fully automatic packaging machines, in which a continuous tube is formed from the sheet of packaging material.
  • the sheet of packaging material is sterilized in the packaging machine by applying a chemical sterilization agent, which is then removed after sterilization is completed.
  • the sheet of packaging material is maintained in a closed, sterile environment and is folded and sealed longitudinally to form the tube.
  • the tube is filled from above, by means of a pipe, with the pourable food product and is formed, sealed and subsequently cut along equally spaced transversal cross sections.
  • Pillow packs are obtained thereby, which have a longitudinal sealing band, a top transversal sealing band and a bottom transversal sealing band, and which are then folded mechanically to form respective finished substantially parallelepiped-shaped packages.
  • the packaging material may be cut into blanks, which are formed into packages on forming spindles, and the resulting packages are filled with the food product and sealed.
  • a package is the so-called "gable top” package commonly known by the trade name Tetra Rex (registered trademark).
  • Opening devices of such type generally comprise:
  • the frame is fitted over a so-called prelaminated hole, i.e. a hole formed through the base layer only and covered, by means of a lamination process, by the other lamination layers of the packaging material, including the layer of gas-barrier material.
  • the frame is fitted, typically glued, onto the pierceable portion of the prelaminated hole, which is made of such lamination layers.
  • the pierceable portion may be defined by a patch attached to the packaging material to close a hole formed, in this case, through the full thickness of the packaging material.
  • Threaded opening devices are known, in which the frame typically comprises an externally threaded, substantially cylindrical-shaped collar, whereas the cap comprises an internal thread and is initially screwed to the collar. Furthermore, the cap is normally injection-molded integrally with a relative tamper-evidence ring, which is coaxially connected to the cap itself by means of a plurality of breakable bridges and which is configured to remain fitted to the collar once the bridges are broken and the cap is unscrewed.
  • the opening device comprises a pull-off tongue coupled to the pierceable portion and configured to be torn by the user, once the cap has been unscrewed from the frame.
  • the known opening devices comprise a substantially tubular cutting member screwed inside the collar and having an edge with a number of substantially triangular end teeth, which cooperate with, and partly detach, the pierceable portion from the relative wall, preferably with the exception of a small-angle portion, so as to avoid the torn pierceable portion to fall into the inside of the package after cutting.
  • the cutting member is activated by the cap by means of a one-way ratchet-type transmission means, operated during disengagement of the cap from the collar of the frame.
  • the cutting member is movable along a spiral path with respect to the frame, from a raised rest position, in which the end teeth face the pierceable portion, into successive lowered cutting positions, in which the end teeth interact with the pierceable portion, thereby cutting the pierceable portion.
  • number 1 indicates as a whole a package made of a multilayer sheet of packaging material 2, adapted to contain a pourable product, and having a wall, in particular a top wall 4, onto which an opening device 3, preferably made of plastic material, is fitted.
  • package 1 is adapted to contain a pourable food product, such as milk, water, fruit juice or the like.
  • opening device 3 is fitted to an opening area of package 1 by conventional fixing means, such as adhesive substances, e.g. glue, or by means of welding systems, e.g. laser welding or microflame welding.
  • fixing means such as adhesive substances, e.g. glue
  • welding systems e.g. laser welding or microflame welding.
  • packaging material 2 comprises a base layer 5 for providing stiffness and strength, which may be made of fibrous material, e.g. paper or mineral-filled polypropylene material, and a cover layer arrangement 6.
  • base layer 5 for providing stiffness and strength, which may be made of fibrous material, e.g. paper or mineral-filled polypropylene material, and a cover layer arrangement 6.
  • cover layer arrangement 6 comprises a first covering layer 6a and a second covering layer 6b, both made of heat-seal plastic material, e.g. polyethylene film, and covering both sides of base layer 5.
  • first covering layer 6a and second covering layer 6b both made of heat-seal plastic material, e.g. polyethylene film, and covering both sides of base layer 5.
  • Packaging material 2 comprises, at top wall 4 of package 1, a pierceable portion 7 which is covered externally, in use, by opening device 3 and which is configured to be detached, at least partially, from top wall 4 in order to allow the pourable product to exit package 1.
  • pierceable portion 7 defines the opening area to which opening device 3 is fitted.
  • opening area may be a through hole made in the packaging material 2, in particular in the portion of packaging material 2 forming top wall 4.
  • cover layer arrangement 6 also comprises a barrier layer 8 made of gas-barrier material, e.g. aluminum foil or ethyl vinyl alcohol (EVOH) film, which is superimposed on the second covering layer 6b and is in turn covered with a third covering layer 6c of cover layer arrangement 6, made of heat-seal plastic material.
  • gas-barrier material e.g. aluminum foil or ethyl vinyl alcohol (EVOH) film
  • third covering layer 6c forms the inner face of package 1 eventually containing the pourable food product.
  • first covering layer 6a, second covering layer 6b, barrier layer 8 and third covering layer 6c define lamination layers applied, by a lamination process, to base layer 5 when producing packaging material 2 in the form of a continuous sheet, before cutting and folding it to form package 1.
  • Pierceable portion 7 is defined by a through hole formed only through base layer 5 and covered by first covering layer 6a, second covering layer 6b, barrier layer 8 and third covering layer 6c.
  • pierceable portion 7 is made of the above-mentioned lamination layers and closes the through hole formed in base layer 5.
  • pierceable portion 7 is an integral part of cover layer arrangement 6.
  • pierceable portion 7 may be made of only one or more of first covering layer 6a, second covering layer 6b, barrier layer 8 and third covering layer 6c.
  • pierceable portion 7 may be made solely of barrier layer 8.
  • pierceable portion 7 may be defined by a patch attached to packaging material 2 to cover a hole formed, in this case, through the full thickness of packaging material 2.
  • pierceable portion 7 has an axis A, preferably orthogonal relative to top wall 4, in particular vertical when package 1 stands on a bottom wall (not shown and substantially parallel to top wall 4).
  • pierceable portion 7 has a substantially circular shape concentric to axis A.
  • opening device 3 comprises:

  • collar 14 coaxially defines passage 11.
  • opening 11a is arranged coaxially also to axis B.
  • opening 11a is arranged at an axial end of collar 14, and therefore of passage 11, opposite to top wall 4.
  • Cap 12 comprises a substantially flat circular portion 15 and a cylindrical portion 16, which projects from flat portion 15 along a longitudinal axis C of cap 12 itself and which is configured to coaxially engage collar 14 in order to close passage 11 and opening 11a.
  • collar 14 is provided with an outer thread 17 extending onto an external lateral surface 18 of collar 14 itself, and cap 12 is provided with an inner thread 19 extending onto an internal lateral surface 20 of cylindrical portion 16.
  • outer thread 17 and inner thread 19 are configured to mutually engage so as to determine, in use and under the action of the user, unscrewing and screwing of cap 12 relative to frame 10, and therefore collar 14, thereby causing opening and closing of passage 11.
  • Opening device 3 further comprises tamper-evidence means, in particular a tamper-evidence ring 21, preferably formed integrally with cap assembly 12a, for example injection-molded together with cap assembly 12a, and initially connected coaxially to cap assembly 12a at least by means of a number of breakable connecting bridges.

  • cap assembly 12a is fitted initially to frame 10 in a closed position, in which cap 12 is screwed completely onto collar 14; in this condition, cap assembly 12a and tamper-evidence ring 21 are still connected to one another. Then, during first disengagement of cap 12 from collar 14, the connecting bridges are configured to break apart, thereby freeing cap assembly 12a from frame 10.
  • Tamper-evidence ring 21 is fitted to frame 10, in particular fitted around collar 14 coaxially to axis B.
  • collar 14 comprises an engagement portion 23 configured to be engaged by tamper-evidence ring 21 and configured to retain tamper-evidence ring 21 during and after first unscrewing of cap 12.
  • the axial distance of engagement portion 23 from opening 11a is greater than the axial distance of outer thread 17 from opening 11a.
  • the axial distance of tamper-evidence ring 21 from opening 11a is greater than the axial distance of outer thread 17 from opening 11a.

  • recesses 23a are distributed circumferentially onto external lateral surface 18 of collar 14, relatively to axis B, and protrusions 21a are distributed onto an internal lateral surface of tamper-evidence ring 21 facing external lateral surface 18.
  • cap assembly 12a During fitting of cap assembly 12a onto frame 10, tamper-evidence ring 21 is fitted to collar 14 so that protrusions 21a face recesses 23a, thereby engaging corresponding recesses 23a.
  • each recess 23a acts as rotational and axial stop for the respective protrusion 21a, thereby preventing the angular motion, i.e. the rotation, of tamper-evidence ring 21 with respect to axis B, only in the above-mentioned unscrewing direction (opening direction).
  • recesses 23a could allow a minor angular motion of tamper-evidence ring 21 with respect to axis B in the opening direction, for example due to manufacturing tolerances.
  • tamper-evidence ring 21 is rotatably fitted to collar 14 with respect to both opening direction and closing direction - i.e. it is freely rotatable in both directions with respect to collar 14.
  • tamper-evidence ring 21 is angularly fixed with respect to axis B in both opening direction and closing direction.
  • cap 12 is moveable between:
  • the connecting bridges break, due to the torque applied thereto by the user, thereby at least partially unconstraining cap assembly 12a from tamper-evidence ring 21 and permitting the unscrewing of cap 12 off collar 14.
  • opening device 3 further comprises a known tubular cutting member 24 which engages collar 14 axially and in a movable manner and is activated by cap 12 to interact with pierceable portion 7 to open package 1.
