Definitions

  • the present invention relates to a reclosable opening device for sealed sheet material packages of pourable food products.
  • 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 sheet packaging material.
  • a typical example of this type of package is the parallelepiped-shaped package for liquid or pourable food products known as Tetra Brik Aseptic (registered trademark), which is made by folding and sealing a web of laminated packaging material.
  • the packaging material has a multilayer structure comprising a layer of fibrous material, e.g. paper, covered on both sides with layers of heat-seal plastic material, e.g.
  • polyethylene and, in the case of aseptic packages for long-storage products, such as UHT milk, also comprises a layer of oxygen-barrier material, defined, for example, by aluminium foil, which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material eventually defining the inner face of the package contacting the food product.
  • a layer of oxygen-barrier material defined, for example, by aluminium foil
  • Such packages are normally produced on fully automatic packaging machines, on which a continuous tube is formed from the web-fed packaging material; the web of packaging material is sterilized on the packaging machine itself, e.g. by applying a chemical sterilizing agent, such as a hydrogen peroxide solution, which, once sterilization is completed, is removed, e.g. vapourized by heating, from the surfaces of the packaging material; and the web of packaging material so sterilized is kept in a closed, sterile environment, and is folded and sealed longitudinally to form a vertical tube.
  • a chemical sterilizing agent such as a hydrogen peroxide solution
  • the tube is filled with the sterilized or sterile-processed food product, and is sealed and cut along equally spaced transverse sections to form pillow packs, which are then folded mechanically to form the finished, e.g. substantially parallelepiped-shaped, packages.
  • the packaging material may be cut into blanks, which are folded on forming spindles into packages, which are then filled with the food product and sealed.
  • the so-called "gable-top” package known by the trade name Tetra Rex (registered trademark).
  • packages of the above type have been fitted with reclosable opening devices, which substantially comprise a frame defining an opening and fitted about a hole or a pierceable or removable portion in a wall of the package; and a cap hinged to the frame.
  • the cap is normally molded integrally with the frame, and is initially sealed to it, along a peripheral edge surrounding the opening, by a thin breakable annular connecting portion. Once unsealed, the cap is movable between a closed position, in which it cooperates hermetically with the frame, and an open position.
  • threaded caps separate from and initially screwed to the frame, are also used.
  • opening devices of the above type are made of easy-to-break plastic material, normally polyethylene.
  • Polyethylene however, has the drawback of being a poor oxygen barrier. Consequently, the side of the packaging material eventually defining the inside of the package must be fitted over the hole with an additional "patch" element defined by a small sheet of heat-seal plastic material, and the opposite side of the packaging material must be fitted with an oxygen-barrier element, e.g. a pull-off tab, which is heat sealed to the patch element and provided with a layer of aluminium.
  • an oxygen-barrier element e.g. a pull-off tab
  • Providing the packages with barrier and patch elements involves additional processing of the packaging material before it is sterilized and folded and sealed to form the vertical tube, thus increasing production time and cost of the packages.
  • the user must also remove the barrier element for access to the content of the package.
  • Reclosable opening devices have therefore been proposed, by which to unseal the package in one operation, while at the same time acting as an effective oxygen barrier.
  • opening devices of this type substantially comprise a frame defined by a cylindrical collar defining a pour opening, and by a base flange fitted about a pierceable portion of the package; a removable cap which screws onto the outside of the collar of the frame to close the opening; and a substantially tubular cutting member, which screws inside the collar of the frame, and comprises, at one end, a cutting edge with one or more end teeth which cooperate with the pierceable portion of the package to detach it incompletely from the relative wall, i.e. all except a small-angle portion.
  • the cap is normally molded integrally with a relative tamperproof ring connected coaxially to the cap by breakable radial connecting spots.
  • the cap described is pressed onto the frame so that the relative tamperproof ring clicks past the thread portion of the frame close to the base flange.
  • the cutting member is operated by the cap by means of ratchet-type one-way transmission means, which are activated when disengaging the cap from the collar.
  • the cutting member moves in a spiral, with respect to the frame, from a raised rest position, in which its cutting edge faces the pierceable portion, to successive lowered cutting positions, in which the cutting edge interacts with the pierceable portion.
  • the height of the opening devices applied to the packages is kept as low as possible.
  • multistart cap and frame threads which also assist the user in opening and closing the package. That is, whereas single-start solutions require a full turn or slightly more of the cap, long-pitch multistart threads enable the cap to be removed completely, or fully tightened, by turning it roughly 180°.
  • Short opening devices with multistart threads are unsuitable for packages containing fizzy drinks, on account of the long-pitch threaded connection failing to adequately retain the cap in opposition to the pressure produced inside the package by the gas in the product.
  • the gas in the product could therefore cause the cap to be blown off the package when the pierceable portion is sheared.
  • a reclosable opening device for sealed packages of pourable food products as claimed in Claim 1.
  • Number 1 in Figure 1 indicates as a whole an aseptic sealed package for pourable food products, e.g. a parallelepiped-shaped package known as Tetra Brik Aseptic (registered trademark), which is made from sheet packaging material, as described previously in detail, and is fitted with a reclosable opening device 2 made of plastic material and applied to package 1 in conventional manner, e.g. using adhesives or microflame or laser sealing methods.
  • Tetra Brik Aseptic registered trademark
  • the packaging material has a multilayer structure, and comprises, at a top wall 3 of package 1, a circular pierceable portion 4 of axis A ( Figures 2, 4 and 5), which in use is covered externally by opening device 2 and is detached at least partly from wall 3 to enable the product to be poured out of package 1.
  • the packaging material comprises a layer of fibrous material 5, normally paper, covered on the outside and inside with respective laminated sheets 6, 7 normally defined by one of more layers of heat-seal plastic material, e.g. polyethylene.
  • the inner laminated sheet 7 also comprises a layer of barrier material interposed between the layers of heat-seal plastic material.
  • Pierceable portion 4 is defined in this case by respective portions of outer and inner laminated sheets 6, 7 covering a hole 8, of axis A, formed in the layer of fibrous material 5.
  • the pierceable portion is defined by a preferential tear line (not shown) formed in the layer of fibrous material and defined by a succession of perforations.
  • a preferential tear line (not shown) formed in the layer of fibrous material and defined by a succession of perforations.
  • opening device 2 comprises a frame 10 defining a through hole 11 of axis A, through which the food product is poured, and fixed to wall 3 of package 1, about pierceable portion 4; a cap 12 formed separately from frame 10 and fitted coaxially to frame 10 to close hole 11; and a tubular cutting member 13, of axis A, which engages hole 11 in axially and angularly movable manner, and is activated by cap 12 to interact with pierceable portion 4 of wall 3 to unseal package 1.
  • frame 10 comprises a circular annular base flange 14, an end surface of which is fixed to wall 3 of package 1, about pierceable portion 4, and from the radially inner edge of which projects axially a cylindrical collar 16, of axis A, defining hole 11.
  • collar 16 On respective opposite lateral surfaces, collar 16 comprises an external thread 20 and an internal thread 21, which, in use, engage relative threads 22, 23 of cap 12 and of cutting member 13, and slope in opposite directions with respect to axis A.
  • collar 16 comprises an annular rib 24 interposed axially between one end of thread 20 and flange 14, and located a constant axial distance from flange 14.
  • Collar 16 also has one or more lateral windows 18 for releasing any gas in the food product, and so reducing the pressure inside package 1, when cap 12 is unscrewed off frame 10 and shearing of pierceable portion 4 commences.
  • Cap 12 is defined by a hollow cylindrical body bounded by a circular top wall 25 for closing hole 11, and by a cylindrical lateral wall 26, which projects from a peripheral edge of top wall 25, is provided internally with thread 22, and screws onto collar 16 of frame 10.
  • Top wall 25 has a projecting annular rib 27 adjacent to lateral wall 26 and defining, with lateral wall 26, a seat for receiving the top end edge of collar 16.
  • Cap 12 is normally molded integrally with a relative tamperproof ring 28 connected coaxially to an end edge of cap 12, opposite top wall 25, by a number of breakable radial connecting spots.
  • Cap 12 is initially fixed to frame 10 in a sealing position, in which it is screwed completely onto collar 16, with its bottom end edge and tamperproof ring 28, still connected to each other, on opposite sides of rib 27 of collar 16 ( Figure 4).
  • cap 12 is movable between an open position, in which it is unscrewed off collar 16 and detached from frame 10, and a closed position closing hole 11.
  • Initial rotation of cap 12, when unsealing package 1, breaks the connecting spots between cap 12 and tamperproof ring 28, which rests on base flange 14. More specifically, the connecting spots are broken by spiral rotation of cap 12 away from rib 24 of frame 10, and by rib 24 simultaneously retaining tamperproof ring 28.
  • cutting member 13 which has thread 23 on its outer surface, is fitted in known manner inside collar 16 of frame 10 by thread 23 engaging thread 21, and comprises an end edge 30 having face cutting means 31 - in the example shown, one cutting tooth - which cooperate with pierceable portion 4 to unseal package 1.
  • Connection of collar 16 of frame 10 to cutting member 13, and operation of cutting member 13 by cap 12 are described below only as required for a clear understanding of the present invention. Further details can be found in Patent Application EP-A-1088764, the content of which is considered included herein by way of reference.
  • Threads 21 and 23 define, when unsealing package 1, a helical path, of axis A, of cutting member 13 through pierceable portion 4, from a raised rest position ( Figure 4) to a bottom open position (not shown). More specifically, in the raised rest position, cutting member 13 is housed completely inside collar 16, with cutting means 31 facing pierceable portion 4; and, in the bottom open position, cutting member 13 projects axially with respect to collar 16, has penetrated a given distance inside package 1, and has completely cut pierceable portion 4, leaving it attached by a small-angle portion to wall 3.
  • transmission means 32 comprise a number of first teeth 33 - four in the example shown - having a saw-tooth profile, projecting from top wall 25 of cap 12, and equally spaced angularly about axis A; and a number of second teeth 34 - eight in the example shown - also having a saw-tooth profile, and which project radially from an inner surface of cutting member 13, and mesh in axially free, angularly integral manner with teeth 33 along the release travel of cap 12 from collar 16 when unsealing package 1. More specifically, the release travel of cap 12 is shown in Figure 1 by anticlockwise rotation R of cap 12 about axis A.
  • each tooth 33 is defined, towards lateral wall 26, by two oblique, outwardly converging sides 36, 37; the side (36) sloping more sharply, with respect to the radial direction joining relative tooth 33 to axis A, defines a stop for a relative tooth 34 in rotation direction R of cap 12; and the other side (37) allows teeth 34 to slide angularly in the opposite rotation direction.
  • Each tooth 34 extends the full axial height of cutting member 13, and has, in cross section, the same profile as teeth 33, defined by two oblique converging sides 38, 39; and the side (38) sloping more sharply, with respect to the radial direction joining tooth 34 to axis A, faces side 36 of a relative tooth 33.
  • thread 20 of frame 10 comprises, at a portion engaged by thread 22 of cap 12 at the transient stage between detachment of tamperproof ring 28 and initial shearing of pierceable portion 4 by cutting means 31, successive thread portions 40, 41 separated by a distance D1 smaller than the distance D of the rest of thread 20, so as to eliminate, at said portion, the clearance between threads 20 and 22.
  • This feature enables perfect control of the rotation of cap 12 when unsealing the package, to minimize the risk of cap 12 being blown off in the case of fizzy products.
  • the user experiences only one prolonged force peak when unsealing the package.
  • thread 20 is a three-start type, and thread portions 40, 41 form part of independent threads.
  • thread 20 may be a single-start type, and thread portions 40, 41 may be defined by spaced, facing portions of the same thread.
  • the distance between thread portions 40, 41 is reduced to D1 by altering the course of one (40) of the two thread portions so that it converges towards the other (41).
  • Number 2' in Figures 8 and 9 indicates as a whole a different embodiment of an opening device in accordance with the teachings of the present invention, and which is described below only insofar as it differs from opening device 2, and using the same reference numbers for component parts corresponding or equivalent to those already described.
  • Opening device 2' differs from opening device 2 by the distance between thread portions 40 and 41 being reduced to D1 by shaping one (40) of the two thread portions to bring it closer to the other (41). More specifically, thread portion 40 defines a projection 42 projecting towards the adjacent thread portion 41.
  • Opening device 2, 2' is assembled, before being fixed to pierceable portion 4 of package 1, by inserting cutting member 13 in a predetermined angular position inside collar 16, and by simultaneously or subsequently fitting cap 12 to frame 10.
  • teeth 34 slide axially in pairs on opposite angular sides of sides 36, 37 of a relative tooth 33.
  • Cap 12 is preferably pressed axially onto frame 10, after first positioning cap 12 in a predetermined angular position with respect to cutting member 13. At this stage, threads 20 and 22 engage one another, and tamperproof ring 28 clicks past annular rib 24 of collar 16 towards flange 14. Alternatively, cap 12 may be pressed axially onto the frame and then screwed on collar 16 of frame 10 into a final angular position enabling full use of the screw-off travel of cap 12 when unsealing package 1.
  • cutting member 13 is in the raised rest position inside collar 16, and defines, together with cap 12 closing hole 11, a sealed configuration of opening device 2, 2' on package 1 ( Figures 4, 8).
  • package 1 is unsealed by rotating cap 12 in direction R with respect to axis A to unscrew it off collar 16.
  • cap 12 As cap 12 is rotated in direction R about axis A, the engagement of threads 20 and 22 simultaneously moves cap 12 axially away from wall 3, thus breaking the radial spots connecting it to tamperproof ring 28, which is retained resting axially on rib 24 of collar 16.
  • Teeth 33 of cap 12 are positioned with sides 36 resting against sides 38 of relative teeth 34 of cutting member 13, which is thus also rotated about axis A in direction R.
  • the axial movement of cap 12 away from wall 3 of package 1 corresponds to a simultaneous axial movement of cutting member 13 towards wall 3. More specifically, cutting member 13 is rotated by cap 12 by teeth 33 and 34 contacting at respective sides 36, 38, which are simultaneously slid axially with respect to each other by the spiral movement impressed on cap 12 and cutting member 13 by relative pairs of threads 20, 22 and 21, 23.
  • Cutting means 31 advance angularly through pierceable portion 4 to detach it along its perimeter from wall 3.
  • cutting member 13 is prevented from moving from the bottom open position, by teeth 33 of cap 12 being unable to reach an axial position engaging teeth 34 of cutting member 13. In which position, the sheared portion of pierceable portion 4 is retained inside cutting member 13 to keep hole 11 clear.
  • Package 1 is closed by simply replacing cap 12 on collar 16.
  • window/s 18 in collar 16 of frame 10 permits/permit fast release of the gas to rapidly reduce the pressure exerted on cap 12 from inside package 1, and to restore the normal axial clearance between threads 20 and 22 at the following unsealing stage, with no risk of sudden detachment of cap 12.
