Definitions

  • the invention refers to a method and apparatus for packaging any kind of product in flexible containers and containers thereof.
  • the apparatus of this invention is of an intermittent type. This means that the flexible film used to form the containers stands still during the entire seal forming and product filling, and moves only afterwards to transport the film material to the next machine station.
  • the apparatus can be animated trough pneumatic, electric, hydraulic or mechanic transmission mechanisms, being the forming/filling operation executed independently of the driving device.
  • the film material is winded on a reel, and can be flat or pre-folded. In both cases, idle or driven rollers unwind the material, and a braking device guarantees that the film is unwinded in a controlled way.
  • the film passes a single fold (pillow bag) or a "W" shaped triple fold (stand-up container). After folding, and prior to the point where the film is grabbed by the transport belts, an optional label and zipper can be inserted between the folded sides of the container.
  • Both the label and the zipper are pre-winded on independent reels, each one with its own unwinding mechanism, composed by idle and/or motorized rollers and a braking device to unwind the label and zipper in a controlled way.
  • the unwinding of the label and zipper is synchronized with the unwinding of the film, so the unwinding speed is the same for all the components.
  • a longitudinal weld can be applied to one side of the container, welding one edge of the label to the inner surface of one of the container walls, a back plate must be inserted to separate the label and side to be welded from the opposite container side, otherwise the two sides and the label will be welded together, sealing the container.
  • the zipper is welded to one side of the container.
  • the movement of the label weld bar, zipper weld bar, transverse seals, longitudinal seals, transverse cut, buffer doors, and container opening and closing is fully synchronized to optimise the performance of the apparatus.
  • the role of the buffer doors (39) is to receive the product to be contained from the dosing system (volumetric, weighing or other) and to fully synchronize product drop into the container, on the moment where the opening device (13) opens the belts and the container.
  • the film container material is grabbed by its upper edges (lips) between two transport belts. These belts will sustain and transport the material until the container is fully sealed and filled.
  • transverse weld bars and cutting blades that can be integrated in the same mechanism, or separated.
  • the containers When the containers have transverse seal formed and cut, they are transported to the fill opening, which opens the container allowing the penetration of the product to be contained, and recloses the container, allowing this to be transported to the next station.
  • a longitudinal weld is applied on top of the container, sealing it.
  • a second longitudinal seal is applied below the label, and if a zipper is present, a seal is also applied on the unwelded side of the zipper.
  • the present invention relates to a container formed from a flexible flaccid heat-sealable sheet-like material (like PET), applicable for containing solid, granular or liquid products, said container comprising a hermetically sealed cavity designed to enclose the product contained in the container, which is formed from at least two side walls, which may have a base configured in such a way to allow the container to stand up, a closure device (e.g. ZIPPER®) to make the container reclosable, and /or a label contained inside the container, separated from the product cavity by a weld.
  • a closure device e.g. ZIPPER®
  • Optional vacuum can be created inside said product cavity.
  • An apparatus and a method of packaging and the container thereof are also disclosed.
  • Containers formed from flexible materials which contain liquids, formless substances or solids, and the devices to produce said containers are well known.
  • fish or fish slices, granulated food, drink containers, cosmetics and many others. They are generally formed so they are shaped like a pillow, or can contain a base to allow the container to stand up right when full, and usually the container material is pre-printed.
  • an adhesive label is applied on the outside, or a discrete carton, paper or plastic label is inserted inside the container, being separated from the contained product by an extra seal.
  • a reclosable device can also be fit to the container to allow it to be resealable after the first use.
  • Vacuum can also be created inside the container, helping to increase life of perishable products.
  • VFFS Vertical form-fill-seal machines
  • the bottom of the container can also be shaped to form a base to allow the container to stand up.
  • a reclosable device can also be welded to one side of the container. Transverse seal bars form the side welds of the container. The container is then opened by suction pads or pincers, filled with the product to be contained, and sealed with a horizontal weld.
  • VOLPAK W02007/031330
  • HFFS can also operate with pre-made container.
  • bags or packs of containers connected together are fed into the apparatus, the fill opening is opened by a mechanical pincer or vacuum the product to be contained is inserted into the bag and this container is sealed.
  • Such machines as described on WO02/070349 (Goglio ) can also to make packaging in vacuum.
  • the main disadvantage is the need to prepare the containers in advance, and higher cost compared to flat laminar material.
  • HFFS HFFS
  • BDHFFS belt driven horizontal form-fill-seal
  • Fig. 5A a reel
  • Fig. 5B a folding device
  • Transverse seal bars (100) weld the sides of the container, and separate then up to a certain height (101), and not straight to the top, like standard HFFS.
  • the unsealed height (102) between the top of the container material and the top of the transverse seals is necessary to allow the material to go around a fixed fill opening (103), and the excess of material is cut after the product to be packed is inserted in the container and the container sealed (104). This excess of material is wasted (105), constituting one major disadvantage of this type of machines, which can waste as much as 20% of the packaging material with evident costs.
  • BDHFFS polyethylene material
  • BDHFFS machines are interesting due to their lower costs compared to HFFS and to the easiness in the change of container sizes, which involves the change of the forming tube on VFFS, an expensive apparatus requiring a skilled worker to carry the change, this taking in certain cases 30 minutes to fulfil.
  • Another advantage of the BDHFFS against standard HFFS and VFFS is the possibility to support the container by its base during the filling and sealing process preventing these from bursting or perforating with product impact.
  • VFFS machines are particularity sensitive to this due to the very high drop height.
  • BDHFFS also support the container by its entire upper edge, and not only by the corners as on HFFS, ensuring safer operation when handling heavy containers.
  • BDHFFS machines are known by handling easily containers of vegetables with 25Kg in perfect safety (see GILLENKIRCH, H-TECH).
  • Said labels can be of self-adhesive type, being applied at the outside of the container, exposed to water and friction, or can be in paper, carton or plastic inserted inside the container. In the latter case, the product to be contained is introduced inside the container, a first seal is made, the label is inserted above the first seal and a second seal is made above the label protecting it against friction or water damage, but makes the filling and labelling process very slow, reducing overall speed of the apparatus.
  • the apparatus and method which are object of the present invention, provide solutions to the problems raised by the prior art. This is done by providing a method to eliminate waste of film on BDHFFS machines, and allowing a fast and reliable way of introducing a label inside the container, fitting a reclosable device and creating vacuum into the package. Moreover the container object of the present invention presents innovative ways of applying a label and a reclosable device.
  • the container is composed of planar flexible material, and manufactured by a single folded sheet of flexible laminated heat sealable material, or by two separate sheets welded together, an optional closure or reclosable device can be fitted, and an optional label can be fitted in the inside of the container.
  • the bottom of the container can be flat, or have a folded base to allow the container to stand up.
  • the invention includes an apparatus and method for the shaping, filling and sealing of containers of flexible and soft laminar material.
  • the apparatus which comprises an unwinding station (figs.1 , 2 , 3 , 4 ), a container pre-shaping station (1) with the optional inclusion of a reclosable device (for example of the kind known as zip®) (2) with the optional inclusion of a label placed at the inside of the container (3); a container filling station (4); a container sealing station (5) with an optional vacuum air extraction from the inside of the container (6).
  • the packaging material can be presented winded flat (7), as shown in figure 1 or pre-folded (8) as shown in figure 2 .
  • a reclosable device (2) is welded to one wall of the container by a welding bar (9) (front or rear), and a label (3) is unwinded between the two walls of the container material.
  • this label can be welded to one wall of the container material (front or rear) by a welding bar (10).
  • the sides of the label are welded together to the container material by the transverse seal bars (11) forming simultaneously the two sides of the bag (27, 28), as shown in figure 8 .
  • the bags are transversely separated by a blade mounted in the same transverse seal bar (11), or by a following cutting mechanism (12), thus moving transverse separate cut (29), as shown in figure 9 .
  • the filling station comprises a device (13) to open the bags, grabbed between the transport belts (14) and roller fingers or sliding pads (15), fill them with the product to pack which can be solid, liquid or granular, and close it.
  • the horizontal seal station removes the air from the inside of the container trough the suction on ducts (6), makes one horizontal seal on top of the container (16, 32), the reclosable device (2) is welded to the free side of the container by the seal bar (17), and if there is a label, a second seal is made separating the label from the packed product (18, 31).
  • the reclosable device and the label can be applied prior to film folding.
  • said apparatus comprises idle or motor-driven rollers (36) to unwind said container material (7) (film or sheet).
  • container material (7) film or sheet.
  • the two faces of the packaging material used to manufacture containers similar to these of the invention have different properties; the inner surface will be in contact with the product to be contained, and the outer surface acts as printing medium to carry products information and advertising.
  • the "W" shaped bottom is not welded in the outer surface resulting in an anaesthetic look, and poor container self-standing properties.
  • a set of aligned perforations is made, by a perforating device formed by two pairs of transversally aligned perforations (35).
  • This folding device can be aligned with respect to the middle section of the container material, allowing the formation of equal sides of the container, or shifted to one side to allow the production of two unequal faces, the container being handled by only one lip (edge).
  • a compressing device helps flatten the folded container material (37).
  • a flat continuous label (3) is applied between the two walls of the container material (22, 23) and one or two longitudinal seals (10) can be applied to weld the label to one of the walls of the container.
  • a zipper (2) can also be unwinded between the two walls of the container, being welded to one wall of the container (22) by a longitudinal seal (9).
  • transverse welding station with the purpose of forming at least one set of side weldings (27, 28) and a cutting device can be integrated on the transverse welding station (11) or immediately after (12) cutting the transverse weld in the middle area with cut (29), individualising the containers.
  • a container opening device (4, 13) being prepared to open at least one container, adapted to open the transport belts (14), ( figs 1 , 2 , 3 , 4 ) and the container opens the two lips (47) grabbed between the transport belts (14) and the opening mechanism (13, 15), of at least one container allowing the insertion of the product to be packed.
  • This said opening device allows the progression of the containers without damaging the transverse seals as it allows the two container lips (edges) to be close together during container transport along the machine ( Figs. 18 , 19(A;B;C) - detail B).
  • the longitudinal seal bars 16 and 18 seal the container cavity (30) and of the top of the container, the reclosable device is welded (17) to the side opposite to the previous weld (9), the final separation of the containers is made by cutting device (46) which separates the last transverse section of the container material. Alternatively, a continuous strip is cut above the longitudinal seal by the cutting device (45).
  • Figures 5 , 5A , 5B concern to prior art: machines: usually the container material is presented pre-folded on a reel ( Fig. 5A ) although some machines are fitted with a folding device, like HFFS ( Fig. 5B ).
  • Transverse seal bars (100) weld the sides of the container, and separate then up to a certain height (101), and not straight to the top, like standard HFFS.
  • the unsealed height (102) between the top of the container material and the top of the transverse seals is necessary to allow the material to go around a fixed fill opening (103), and the excess of material is cut after the product to be packed is inserted in the container and the container sealed (104). This excess of material is wasted (105), constituting one major disadvantage of this type of machines, which can waste as much as 20% of the packaging material with evident costs.
  • Figures 6 to 12 illustrate the container, which is object of the invention made of a flat material (film or sheet), at different steps of the method of invention.
  • foldings (19), (20) and (21) are parallel to each other shaping the container material in a "W" shape, defining front (22) and back (23) walls of the container and two bottom faces (24) and (25).
  • the step illustrated in figure 7 represents the folded container material with the label material (3) (paper or plastic) inserted between the two walls (22) and (23), and the optional reclosable device (2) placed below the label.
  • the label material (3) paper or plastic
  • the step illustrated in figure 8 represents the container with side transverse seals (27) and (28) and again the label (26) which was welded at the transverse seals, and the reclosable device (2) which was melted and welded together with seals (27) and (28)
  • the step illustrated in figure 9 represents the container with transverse seals (27) and (28) where a separation transverse cut (29) has been made (symbolic representation by scissors) for separating adjacent containers.
  • the step illustrated in figure 10 represents the container with the product to be packed inserted into the container cavity (30) with the longitudinal seals (31) and (32) behind the reclosable device (2) a longitudinal seal is made to secure it on container wall (23). It was previously welded to wall (22).
  • the step illustrated in figure 11 represents the container with all the seals (27, 28) and (31, 32) and where it is depicted the final longitudinal cut (symbolic representation by scissors) to trim the top (33) of the container above the top longitudinal seal (32).
  • figure 12 represents the container with all the seals (27, 28, 31, 32) and the final transverse cuts (34) at the sides of the container made to separate the containers.
  • Figure 13 represents a perspective view of the closed labelled container and two cross-sectional views (A-A and B-B). In this case it's a stand-up bag. Preferably seals are made by hot welding. Perforation (35) was not applied, either because the outer surface of the film allows welding, or simply was decided to leave the two folds unwelded against each other.
  • Figure 14 represents another embodiment of the closed labelled container with reclosable device and two cross-sectional views (A-A and B-B), in this case it is a stand-up bag with perforations (35) applied to allow the welding of the outer surface of the folded bottom.
  • Fig. 15 represents another embodiment of the closed labelled container and two cross sectional views (A-A and B-B). In this case it is not a stand-up bag since the bottom of it ends up with a sharp folded edge.
