Definitions
- the present invention relates to a method of applying a covering layer over the pouring opening of a packaging container, and also to an apparatus for reducing the method into practice.
- Packaging containers of the single-use disposable type intended for consumer beverages such as milk, juice or the like are available in a multiplicity of different designs, for example plastic bottles or flexible packaging containers which are produced by folding and sealing of laminates comprising layers of paper, plastic and possibly also aluminium foil.
- Other types of packaging containers also occur on the market and all share the common feature that they are provided with some form of opening arrangement.
- One such commonly occurring arrangement is a prefabricated pouring opening which is possibly provided with a projecting neck, and a screw O press cap which, like the neck, may be manufactured from thermoplastic, injection moulded material.
- tamper-proof device i.e. a device which indicates prior opening, in that a safety fitting, for example a ring or a diaphragm, has been ruptured or visibly deformed.
- a simple version comprises a covering layer of, for instance, an aluminium foil and/ or plastic which is located under the cap and sealed to the packaging container or to the neck extending around the pouring opening.
- the covering layer is connected only to the neck, which implies that the consumer, having removed the cap manually, must tear off or otherwise penetrate the covering layer in order to permit emptying of the contents of the packaging container, which gives the consumer a satisfactory guarantee that the package has not previously been opened.
- packaging containers which are interiorly sterile and are intended to be filled with sterile contents of long shelf life, since the demands on hygiene in handling of the covering layer are extreme indeed.
- the handling of the covering layer must, in such cases, take place in a closed space, and as few details and parts as possible should come into contact with the covering layer, so as to reduce the risk of its becoming contaminated.
- the placing of the covering layer in the correct position (possibly with a projecting gripping portion) in the correct orientation must also take place in a closed, sterile space, which further impedes rapid and rational handling and application of the covering layers to the individual packaging containers.
- One object of the present invention is to realise a method of applying a covering layer over a pouring opening, which makes it possible, in a simple and rational manner, reliably to handle the covering layer in order, in as few working stages as possible, to form, transfer and seal a covering layer portion to the pouring opening of a packaging container.
- a further object of the present invention is to realise a method of applying a covering layer over a pouring opening, the method making it possible to supply the layer portions by means of a carrier from which they are removed, formed, transferred and sealed in the correct position over the pouring opening of a packaging container.
- a method of applying a covering layer over the pouring opening of a packaging container has been given the characterizing feature that the layer portion of desired surface area is separated from a carrier and temporarily connected to a reciprocating work surface whose surface area is less than the surface area of the layer portion, whereafter a section of the layer portion projecting outside the work surface is folded parallel with the direction of movement by means of a stationary folding device, and the layer portion is connected to an edge region surrounding the pouring opening.
- One object of the present invention is further to realise an apparatus for carrying the method into effect, i.e. an apparatus which makes it possible to transfer a covering layer portion of the desired configuration and size to the pouring opening of a packaging container, and to seal the covering layer portion to the edge region of the pouring opening.
- a further object of the present invention is to realise an apparatus of the above-outlined type, the apparatus making it possible to transfer with great precision a layer portion to and seal it over the pouring opening of a packaging container.
- Yet a further object of the present invention is to realise an apparatus of the above-outlined type, the apparatus being of simple construction and of such design that the covering layer may be handled reliably with the aid of few parts coming into contact with the covering layer.
- Still a further object of the present invention is to realise an apparatus of the above-outlined type, the apparatus making it possible to sterilise the covering layer and handle and also apply it under sterile conditions without the risk that the covering layer and /or the pouring opening of the packaging container comes into contact with bacteria from the ambient atmosphere.
- an apparatus for applying a covering layer over the pouring opening of a packaging container has been given the characterizing feature that it includes an applicator with a reciprocating transfer device with a work suiface, a stationary folding device disposed along the path of the movement of the transfer device, and means for sealing a layer portion to an edge region surrounding the pouring opening.
- Fig. 1 is a schematic side elevation, partly in section, through an applicator according to the invention, during three succeeding work phases (Figs. 1A-C);
- Fig. 2 is a perspective view of an upper portion of a packaging container with a neck which has been provided with a covering layer portion according to the present invention;
- Fig. 3 is a schematic top plan view of the neck according to Fig. 2, the correct position for a planar, unfolded covering layer portion having been indicated by means of ghosted lines.
- the method and the apparatus according to the present invention are intended to be utilised in a filling and packing machine of the type which, with or without a forming stage, handles and fills prefabricated packaging containers via a pouring opening.
- the method and the apparatus according to the invention are particularly adapted for use together with such machines of the type as are utilised for handling packages intended for sterile contents under aseptic conditions.
- the method and the apparatus according to the invention are intended to be employed in a filling and packing machine of the type which is illustrated and described in Swedish Patent No. 9400506-3, to which reference is made for further details as regards the design, construction and function of the machine.
- an appUcator 1 When it is intended to be employed in the filling machine described in the above-mentioned patent (a machine of the aseptic type), an appUcator 1 according to the invention comprises, on the one hand an applicator assembly 2 and an integral sterilisation apparatus 3.
- the applicator assembly 2 and the sterilisation apparatus 3 are a self-contained unit which is placed immediately above a packing rotor 4 which constitutes part of the filling machine.
- the packing rotor 4 includes, in its upper surface, a number of cup- shaped recesses 5 which merge into through-going holes 6 (Fig. 1C) which discharge at the lower surface of the rotor 4.
- packaging containers 7 of the type illustrated and described in the above-mentioned patent specification, i.e. substantially parallelepipedic (as yet not finally formed) packaging containers which, at their upper ends, have a projecting, preferably threaded package neck 8.
- the package neck 8 has a cylindrical region whose outer diameter is such that a package neck 8 inserted in the hole 6 of the rotor 4 in a gas-tight manner abuts against the inner surface of the hole 6, whereby the upwardly open package neck is screened off from the ambient air.
- the packing rotor 4 is rotary stepwise such that the recesses 5 may in sequence be placed in position beneath the applicator assembly 2, as will be described in greater detail below.
- the sterilisation apparatus 3 includes an elongate sterilisation chamber 9 for a covering strip 10 which is supplied to the apparatus according to the invention from a reel 11 which is freely rotatably suspended in the frame 12 of the machine.
- the strip 10 includes a layer of aluminium foil, and also at least one thermoplastic layer which is located on that side of the strip which is to be connected to the packaging container.
- a driver 13 which includes a driving wheel 14 and a counter-pressure roller 15 cooperating therewith.
- the driving wheel 14 and the counter-pressure roller 15 are located on either side of the covering layer strip 10 in order, possibly with the assistance of a friction-increasing coating, to make for advancement of the strip from the reel 11 in direction towards the chamber 9.
- the driving wheel 14 is connected to an electric drive motor (not shown).
- a sluice gate 16 of per se known construction i.e. a labyrinth seal or a slot-shaped aperture with a number of sealing devices (not shown) extending towards the covering layer strip 10.
- the chamber 9 is provided with a number of inlets and outlets (shown only in Fig.
- the chamber 9 may possibly be divided off by means of additional flexible sealing devices abutting against the covering layer strip 10 (however, this feature is not shown on the Drawings).
- a curved channel or conduit 23 which, from a substantially vertical starting position immediately beneath the sterile chamber 9, curves through 90° so as to discharge horizontally in a working chamber 24 which is provided with inflows (not shown) for sterile air so as to create a given, constant excess pressure and thereby prevent bacteria from penetrating into the working chamber 24.
- the working chamber 24 has a circular working aperture 25.
- the moving parts of the applicator assembly 2 in the form of a substantially vertically reciprocating transfer device 26, a likewise vertically reciprocating cutter device 27 and a cutter spring 28 which is in the form of a helical compression spring abutting against the upper surface of the cutter device 27 and the lower surface of the upper wall of the working chamber 24 and actuating the cutter device 27 to the position illustrated in Fig. 1A in which it abuts against heels (not shown) on the outside of the transfer device 26.
- the upper wall is provided with an aperture for the upper region of the transfer device 26, and a diaphragm 29 which extends between the wall of the working chamber 24 and the cutter device 27 and ensures that the working chamber 24 is insulated from the through passage for the transfer device 26.
- a lever 30 By the intermediary of a lever 30, the upper portion of the transfer device 26 extending out of the chamber 24 is connected to a pneumatic driving cylinder 31 which, via a suspension point in the frame 12, is operative on activation to displace the transfer device 26 reciprocally in the vertical direction.
- a work surface 32 which is substantially planar and possibly provided with a vacuum aperture for connection to a vacuum source (not shown).
- an inductor 33 which is connectable to a voltage source in order to make for induction heating of a metallic object which is located in contact with the work surface 32, i.e. preferably a corresponding portion of the covering layer strip 10.
- Both the sterilisation apparatus 3 and the applicator assembly 2 are thus, with their active parts (i.e. parts coming into contact with the strip), enclosed in a continuous chamber 9, 24, which is provided with sluice gates and is supplied with sterile air at excess pressure in order to ensure perfect hygiene and prevent bacteria from penetrating from outside.
- the apparatus according to the present invention On application of a covering layer over a pouring opening in accordance with the method according to the present invention, use is made of the apparatus according to the present invention, e.g. together with a filling machine of the type described in Swedish Patent No. 9400506-3, in other words an aseptic packing and filling machine which, during simultaneous reforming, fills prepared packaging containers with previously sterilised, liquid contents and seals the packages.
- the individual packaging containers 7 are inserted in the flat-laid state into the filling machine, they being placed at uniform intervals with their upper surface in contact with the underside of the packing rotor 4 and with their projecting package neck 8 inserted into each respective hole 6 in the rotor, the package necks 8 sealingly abutting against the inside of the hole 6.
- the recess 5 in the- rotor 4 forms, together with the working chamber 24, the conduit or channel 23 and the sterilisation chamber 9, a closed space in which sterile atmosphere is maintained by means of a certain excess pressure so that bacteria from the ambient atmosphere are prevented from penetrating.
- a slight space which, however, is insulated in a per se known manner with the aid of aspirated sterile air in such a manner that bacteria cannot penetrate this way into the working chamber 24.
- the pertinent packaging containers may be of any optional type, solely on condition that they display a package neck of such dimensions that it can be applied into the holes 6 of the recesses 5.
- the packaging containers which are described in connection with the above-mentioned patent specification are, however, of the type which is manufactured by cutting, sealing and folding of laminated packaging material, preferably comprising layers of paper, thermoplastic and aluminium foil.
- the packaging material has previously been double-folded and sealed along its edges, and also provided with the package neck 8 which is injection moulded from thermoplastic material, preferably polyethylene.
- the flat-laid packaging containers are sterilised by, for example, radiation sterilisation and are provided with a membrane (not shown) sealing the package neck 8.
- this membrane In connection with the filling operation, which takes place in a filling station located along the packing rotor 4 a slight distance ahead of the applicator assembly 2 (seen in the direction of rotation of the rotor), this membrane is penetrated by a filler pipe designed for this particular purpose, which, during simultaneous forming, fills the packaging containers 7 with the intended volume of contents.
- the rotor 4 is thereafter revolved one step so that the pertinent, recently filled packaging container 7 will be placed immediately beneath the applicator assembly 2. This position is illustrated in Fig. 1A.
- a covering layer portion 10' (Figs. 2, 3) is separated from the covering layer strip 10 and, under simultaneous reforming, is transferred to and sealed against the upper edge of the package neck 8.
- the reforming entails that parts of the covering strip portion 10' projecting outside the neck 8 are folded upwards such that they form pull tabs 10" which are easily accessible to the consumer when the cover layer portion 10' is to be torn off from the neck 8.
- the rotor 4 is once again revolved one step so that the pertinent packaging container 7 may be removed from the rotor and transferred to a cap applicator station in which the neck 8 is provided with a prefabricated cap, for example a screw cap.
- the packaging container is thereafter finished, such that, after possible supplementary final forming, it may be discharged from the machine and transported further to, for example, a point of sale.
- the handling and application of the covering layer strip 10 in the applicator 1 takes place in the described filling machine and the apparatus according to the invention in the foUowing manner.
- the covering layer strip 10 is placed in the form of the reel 11 in connection with the upper infeed end of the sterile chamber 9 provided with the sluice gate 16. With the aid of the driver 13, the strip is fed stepwise down through the sterile chamber 9 and further via the curved channel or conduit 23 to the working chamber 24 where, at the same rate as the rate of advancement, it is severed and transferred to the package neck 8.
- the driver 13 thus pushes the strip 10 through the above-mentioned chamber and no additional advancement device is necessary, since the strip 10 partly consists of relatively rigid aluminium foil which is capable of transferring sufficient driving forces to overcome any possible frictional inertia or resistance from guide means (not shown) during the advancement operation.
- the strip 10 comes into contact with additional drive means on its way through the chambers 9 and 24, which is important to maintain a high standard of hygiene in a simple manner.
- the pertinent strip portion is located in the sterile chamber 9, whose first region (with the aid of sterile air heated to approximately 70- 80°C and fed in via the inlet 17) heats the strip such that, after having passed the first region of the chamber 9, it is substantiaUy at the above temperature.
- the sterile air is evacuated via the outlet 18 which is located a sUght distance beneath the inlet 17.
- gaseous or vaporised hydrogen peroxide H2O2, approximately 70-90°C
- the strip 10 finaUy passes through a passage in which sterile drying air at a temperature of approximately 70- 90°C is aspirated in via the inlet 21 in order, after having ensured drying of excess hydrogen peroxide from the covering layer strip 10, to be evacuated via the outlet 22 located at the lower end of the sterile chamber 9.
- the covering layer strip 10 has passed through the sterile chamber 9 and, after completed sterilisation, is located in the sterile space which is defined by the curved channel 23.
- the strip 10 is advanced stepwise with the aid of the driver 13, each step corresponding to one strip length which somewhat exceeds the corresponding width dimension of the work surface 32 or the package neck 8, as is apparent from Fig. 1A.
- the driving cylinder 31 is activated by being placed in communication with a compressed air source of conventional type (not shown).
- the driving cylinder hereafter activates the transfer device 26 so that this is displaced downwards through the working chamber 24 (Fig. IB).
- the forward, planar work surface 32 of the transfer device 26 will, in such instance, come into contact with the forward portion of the strip 10 which may be retained against the work surface 32 with the aid of vacuum ducts (not shown).
- the cutting edge of the cutter device 27 comes into contact with the strip so that, with the aid of the cutting edge 34 located beneath the strip, a front covering layer portion 10' is severed from the covering layer strip 10.
- the cutter device 27 remains in abutment against the edge 34 until the transfer device 26 is located in its lower position.
- the severing of the covering layer portion 10' from the strip 10 preferably takes place with the aid of slightly obUquely offset cutting devices, whereby the layer portion 10' will have polygonal configuration, and preferably the substantially rhomboid form illustrated in Fig. 3.
- the larger parts of the covering layer portion 10' projecting outside the outer periphery of the neck 8 will hereby form substantially triangular pull tabs 10" which, to facilitate opening for the consumer, are folded upwards so that, in the double-folded state, they are positioned beneath the screw cap subsequently appUed on the neck 8.
- the upward folding of the pull tabs 10" takes place with the aid of the apparatus according to the present invention when the work surface 32 with the adhering covering layer portion 10' passes through the aperture 25 whose peripheral edge functions as the folding device 35. Since, as was mentioned previously, the working aperture 25 is of slightly greater surface area than the work surface 32, the parts of the covering layer portion 10' extending outside the working aperture 25 will be folded parallel with the direction of movement, i.e. upwards during the passage through the working aperture 25. When the transfer device reaches its lower position, the central part of the covering layer portion 10' formed by the preferably circular working aperture will thereby have a diameter which corresponds to the outer diameter of the neck 8.
- the central, circular part of the covering layer portion 10' will also be located in the correct appUcation position in relation to the neck 8 and wiU be displaced by the transfer device 26 into abutment against the upper edge surface of the neck 8.
- the inductor 33 is activated by being placed in communication with a power source such that high frequency heating of the aluminium foil layer of the covering layer portion 10' will create a circular, heated region which corresponds to the upper edge surface of the neck 8.
- the heating of the aluminium layer in turn heats the upper edge of the neck 8 (consisting of thermoplastic), such that this edge melts and makes for seaUng between the lower, thermoplastic-coated surface of the covering layer portion 10' and the neck 8.
- a gas- and Uquid-tight seal takes place of the covering layer portion 10' and the upper edge of the neck 8, which ensures that the packaging container 7 is sealed and closed in bacteria-tight fashion such that its neck 8 may thereby be removed from the sterile chamber, which takes place once the packing rotor 4 has been revolved through an additional step.
- the neck is, as was previously mentioned, fitted with a screw cap whereupon the packaging container is, possibly after additional forming, ready for shipment.
