(20) FIG. 1 shows a pouch container 1 (herein also referred to as a pouch), comprising a front wall 2 and a back wall 2, both walls being made of thin, flexible film material, preferably plastic film material. The walls 2, 2 are sealed along their circumferential edges 3 to form a package for flowable products, for example foodstuff, cosmetics, medicines, etc. In the upper edge of the pouch 1 a dispensing element, herein also referred to as a (dispensing) spout 4, is arranged.
(21) Referring to FIG. 2, the spout 4 of the pouch 1 comprises an elongated dispensing tube 8. The upper end of the dispensing tube 8 is provided with thread windings 10 for attaching a removable end cap (not shown) on the pouch 1 after it has been filled. The lower end of the dispensing tube 8 extends through the upper circumferential edge 3 and extends into the interior thereof so that the dispensing tube 8 may provide a fluid connection between the interior of the pouch and its surroundings so that the content of the pouch may be dispensed when the end cap is removed. The dispensing tube 8 is provided with two lateral elements which serve to attach the pouch 1 to a guiding element 15. More specifically, the dispensing tube 8 comprises an upper flange part 11 and a lower flange part 12.
(22) Guiding rail or guiding element 15 is an elongated section comprising an upper section part 16, a first section side part 17 and a second section side part 18, both section side parts extending roughly orthogonally with respect to the upper section part. At the free ends of the section side parts 17, 18 a slotted carrier part for carrying the spout of a spouted pouch is provided. The carrier part comprises inwardly extending section flanges 19, 20 forming a slot between the free ends of the flanges. The distance (d.sub.1) between the section flange 19 of the section side part 17 and section flange 20 of the section side part 18 is slightly larger than the distance between upright walls 14,23 of the spout and smaller than the width between the upper flange part 11 and lower flange part 12 of the spout 4. Furthermore the section flanges 19, 20 are provided at their respective outer ends with longitudinal ridges 21, 22 along which the upper flange part 11 of the dispensing element (spout 4) of the pouch 1 can be slid. The distance between the upper flange part 11 and the lower flange part 12 of the spout 4 is slightly larger than the distance d.sub.2 between the top and bottom of a longitudinal ridge 21,22 and such that the longitudinal ridges 21, 22 are properly maintained between the upper flange part 11 and lower flange part 12. Therefore the pouch 1 can be moved easily into the guiding element 15 by sliding the spout 4 smoothly (in direction P.sub.1) to be stably maintained within the guiding element by the both flange parts 11, 12 of the spout and the section flanges 19, 20 of the guiding element 15. The number of pouches 1 that can be arranged in the guiding element 15 depends amongst others on the length of the guiding element and the dimensions of the respective spouts 4 of the pouches. As a not limiting example a typical guiding element may carry between 50 and 60 pouches.
(23) Referring to FIGS. 2, 3A-B the first section side part 17 of the guiding means 15 is also provided with an outwardly extending flange forming a male coupling element 26. Similarly the second section side part 18 of the guiding element 15 comprises a female coupling element 27. The male and female coupling elements 26, 27 extend along at least a substantial part of the length of the guiding element 15 and are dimensioned in such a way that the male coupling element 26 of a first guiding element 15 can be inserted (FIG. 3A) into the female coupling element 27 of a second guiding element 15 to mutually connect (FIG. 3B) the first and second guiding elements. The coupling elements 26, 27 are configured to connect two or more parallel guiding elements 15, 15, while still allowing the guiding elements 15,15 to pivot (R.sub.1, FIG. 3B) relative to one another. Since connected guiding elements may still be pivoted relative to each other, they can be positioned in different arrangement. For instance, the guiding elements may be positioned or folded into a tubular arrangement when guiding elements are connected to other guiding elements. This tubular arrangement is shown in FIG. 5. The guiding elements may also be unfolded by pivoting them to a generally flat arrangement wherein the guiding elements all extend in one flat plane, as can be seen in FIG. 11. The guiding elements arranged in the tubular arrangement of FIG. 5 are self-maintaining (or self-supporting) so that the guiding elements can be coupled in such a manner, that they are mutually supported and that they remain in their tubular arrangement without needing any further means. In other embodiments the guiding elements need to have a support element, for instance a sleeve or a tube, to maintain the guiding elements in their tubular arrangement. Examples of these embodiments will be described hereafter.
(24) The female coupling element 27 may have a couple of pivot elements 30 (cf. FIG. 3B) In some embodiments of the invention there are only three pivot elements 30, one positioned close to an outer end of the guiding element 15, one positioned close to the opposite outer end and one in the centre. In other embodiments a different number of pivot elements are used. This arrangement of pivot elements enables the guiding elements to be pivoted in a smooth and stable manner.
(25) FIGS. 3A,3B and 4 show that the lower ends of the side walls of the generally U-shaped guiding element are recessed relative to the upper ends of the side walls. The distance between the lower ends of the side walls is smaller than the distance between the upper ends of the side walls (i.e. the maximum width (w) of the guiding element. In case the lower ends of the side walls are provided with coupling elements, for instance the coupling elements 26,27 depicted in FIG. 4, the distance (D.sub.ce) between the first and second coupling elements 26,27 of the guiding element is smaller than the maximum width (w) of the guiding element. As mentioned above, the width of the guiding element can be made relatively large, making it easier to properly grip the guiding element in case of handling the guiding element in a loading or unloading station, while the distance between the lower ends of the side walls (which distance determines the pitch between containers in neighbouring guiding elements) can be kept relatively small.
(26) FIG. 6 shows the same tubular arrangement 31 of guiding elements 15 represented in FIG. 5, but now the interior 32 of the tubular arrangement 31 is completely filled with a large number of pouches 1. FIG. 6, which is a partly cut-away view of the assembly once it has been arranged in the tubular arrangement 31 and pouches have been moved into the respective guiding elements 15, shows that the spouts 4 inserted into the tube-like arrangement extend in a generally helical trajectory along the length (l) of the guiding elements. In other words, in order to optimize the use of the space available in the interior 32 of the tubular arrangement 31, the pouches may be arranged in the tubular arrangement in angularly displaced positions.
(27) This helical trajectory can be accomplished by inserting the spout of a first pouch in a first guiding element 15, then arranging a second pouch in a partly overlapping manner in the tube-like arrangement by inserting the associated spout into a second guiding element 15(as a non-limiting example, by inserting the spout into the neighbouring guiding element) and repeating the same until the entire interior of the tubular arrangement is filled with pouches. A further example elucidating this filling order of the tubular arrangement of guiding elements is shown in FIGS. 10 and 11. FIG. 10 shows a first revolution of containers extending along the inner circumference of the tubular arrangement. For clarity reasons the containers are depicted so that the distance (l) in longitudinal direction is considerable. In more practical situations the distance (l) is smaller in order to arrange as many containers as possible on the guiding element. FIG. 11 shows the guiding elements and containers of FIG. 10 when the tubular arrangement of guiding elements has been unfolded to a substantially flat arrangement.
(28) The number of guiding elements of the tubular arrangement may vary. Generally the number of guiding elements is n, wherein n=1, 2, 3, 4 . . . . Furthermore, not all guiding elements need to be filled with containers. In embodiments of the invention only a subset of the guiding elements is selectively filled, for instance six or twelve of a total number of 24 guiding elements, depending on the shape and/or size of the pouches, for instance with a view to provide for a compact storage.
(29) In a typical (but non-limiting) example 24 pouches per rotation (revolution) can be accommodated in the tubular arrangement. Depending on the length of the guiding elements and the dimensions of the pouches about 53 rotations can be accommodated in the tubular arrangement. This means that the storage capacity of one assembly can be as high as 1272 pouches.
(30) However, the pouches can be arranged in the interior in alternative order as can be appreciated by the skilled person. Important is that the pouches can be moved into the guiding elements 15 in such a manner that the guiding elements 15 provide a protective cover around at least a part of the pouches. It is appreciated that in the shown embodiment the interior 32 is completely surrounded by guiding elements 15 (except of course at both outer ends thereof). However, in other embodiments one or more of the shown guiding elements 15 can be dispensed with, so that the interior 32 is only partly surrounded by guiding elements. An example of these configurations is shown in FIG. 13.
(31) As mentioned above, the pouches 1 are protected by the tubular arrangement 31 of the guiding elements. The outer ends of the tubular arrangement, however, remain open so that the first few containers and the last few containers in the tubular arrangement are still uncovered in axial direction. In cases wherein additional protection of the pouches is needed, for instance when the interior of the tubular arrangement 31 should be entirely sealed off from the surroundings, cover elements, for instance the end caps 36, 37 shown in FIG. 7, can be removably attached to the outer ends of the tubular arrangement. In the embodiment shown in FIG. 7, the end caps 36, 37 are provided with clamping elements 40, 41 which allow the end caps 36, 37 to be clamped to the guiding elements.
(32) The end caps 36, 37 could have any shape or dimensions. However, in the shown embodiment, the end caps 36, 37 have at least one substantially flat side part 38 so as to enable the tubular arrangement to be supported in a stable manner on a flat surface, for instance a floor or platform of a truck. Furthermore, in further embodiments of the invention, each end cap 36, 37 also has a second substantially flat part 39. The second flat part 39 is able to carry a further tubular arrangement placed on top of the first assembly. In this manner, a number of tube-like assemblies 6,6 may be stacked (cf. FIG. 8). The stacked assembly can be supported in a stable manner on a pallet 42, so that no further stabilisation means are needed. In a typical configuration a single pallet 42 can carry an array of 510 (=50) assemblies and therefore as many as about 501272 (=63,600) pouches.
(33) When the pouches 1 are arranged in the interior of the tubular assembly and, optionally, the end caps have been attached to completely seal off the interior 32, the assembly is ready to be stored and/or to be transported. After transportation of the assembly to its destination, for instance the factory where the pouches are filled with their content, the end caps 36, 37 can be removed and two of the guiding elements 15, 15 can be disconnected from one another. Once two of the guiding elements have been disconnected, for instance by forcing the male coupling element 26 of the first guiding element out of the female coupling element 27 of the second coupling element, the guiding elements which are still in the tubular arrangement, can be pivoted to unfold the tubular arrangement. The pouches are exposed and ready for further processing.
(34) In FIG. 9 an alternative embodiment of the closure of the tubular arrangement of the assembly is shown. Instead of providing the end portions of the tubular arrangement with end caps, the entire tube-like arrangement of guiding elements is sealed by a (transparent or non-transparent) foil, for instance a shrink sleeve that may be shrunk in an oven (not shown) around the guiding elements. The shrink sleeve may cover the tubular arrangement entirely, thereby completely sealing the pouches from the surroundings. More specifically, FIG. 9 shows an embodiment wherein a sleeve 43 has been arranged around the assembly of guiding elements, for instance the assembly in its tubular arrangement 45. The sleeve is a shrink sleeve that has undergone a heat shrink process to shrink the sleeve around the assembly to fully cover the assembly. The sleeve is present around the outer side 46 of the tubular arrangement and also covers the terminal ends 44 thereof. In this manner an excellent protection of the interior of the assembly against external influences can be accomplished. In some embodiments the shrink sleeve also has a support function, namely to support the guiding elements in order to keep them in the tubular arrangement. In further embodiments first a sleeve is shrunk around the tubular arrangement and then one or more end caps are arranged around the end(s) of the tubular arrangement.
(35) In FIG. 11 (in which for clarity reasons only a subset of the total number of pouches is depicted) the guiding elements are shown in an unfolded condition. The guiding elements are pivoted until they extend in a generally horizontal plane. The guiding elements may be supported by a suitable support mechanism (not shown), for instance at the beginning of the filling machine. In this position it is possible to remove the guiding elements one by one. Each guiding element may be individually transported into the feeding mechanism. The pouches may be removed by moving them one by one out of the guiding element and filled with the appropriate substance. It is to be understood that other configurations are also possible, for instance configurations wherein the guiding elements are suspended from a conveyor. The pouches in this configuration extend in a downward manner. Also in this configuration the guiding elements can be disconnected from one another one by one so that each guiding element can be made available for further processing (see FIG. 12).
(36) FIG. 13 shows an embodiment wherein the guiding elements 15 are arranged in a substantially tubular arrangement. Unlike the previously shown tubular arrangements that define a closed circumference, the circumference defined by the guiding elements in this embodiment is open. A longitudinal opening 50 is present between the outer guiding elements 15,15. Also in this tubular arrangement the pouches in the interior 32 still benefit from the partial coverage provided by the remaining guiding elements 15. In this example the guiding elements are kept in place by two end caps 51, 52 that are configured to be clamped along the outer ends of the guiding elements in their tubular arrangement. When the end caps 51,52 are removed, the guiding elements can be unfolded, for instance to the position shown in FIG. 11.
(37) The end cap 51,52 may comprise a circular plate having a circumferential edge 57 along which a first end cap part 58 and a second end cap part 59 can be moved. The end cap parts may be locked to one another at several discrete positions by a locking mechanism 60. In other examples an insert (not shown) is inserted in the free opening 50 and attached to the outermost guiding elements 15,15. The insert not only keeps the folded guiding elements in their tubular shape, but may also provide additional protection for the interior of the tubular arrangements wherein containers may have been stored.
(38) In the longitudinal opening 50 a lid 73 may be arranged to close the tubular arrangement. The lid 73 may comprise a handle 72 to facilitate handling of the lid 73. The opening enables inspection of the interior of the tube, while the handle makes it easier to carry the assembly by hand.
(39) FIGS. 14A and 14B show a further embodiment of the present invention. In this embodiment a number of guiding elements 100 have been attached, for instance glued, to the inner surface 101 of a flexible support 102, for instance a sheet of flexible material, such as soft PVC. The support 102 is flexible to the extent that the guiding elements 100 may be displaced between a flat arrangement (shown in FIG. 14A and the right hand side of FIG. 15) and a tubular arrangement (shown in FIG. 14B). The guiding elements 100 are interconnected indirectly by the respective portions 103 of the support 102 arranged between the guiding elements 100. No direct interconnection like the coupling elements used in the embodiment of FIGS. 2 and 3, are needed. The guiding elements 100 are generally U-shaped and are provided at their longitudinal free edges with appropriate flanges 105,106 extending inward and providing support for the (spouts of the) containers.
(40) FIG. 16 shows an exemplifying example of a preparation device according to the invention. The preparation device 67 in this embodiment comprises a tubular element 68, for instance made of flexible material. The tubular element 68 comprises at its inner surface 69 a number of receiving elements 70 spaced along the circumference of the tubular element and extending in an axial (longitudinal) direction. The receiving elements 70 are configured to receive a number of guiding elements (not shown). Once the receiving elements 70 have received the guiding elements, containers may be arranged in the guiding elements, for instance in the manner as described in connection with FIG. 6. After the guiding elements have been filled with containers, the preparation device 67 may be removed from the guiding elements. Due to the fact that the containers extend in the interior in an intertwined manner the guiding elements remain in their tubular arrangement, even when the preparation device has been removed completely. The tubular arrangement of guiding elements (which are not interconnected directly, at least not in the present example) may be sealed, for instance by shrinking a sleeve around the arrangement.
(41) FIG. 17 shows an alternative embodiment of an assembly according to the invention. The assembly comprises a tube, for instance a plastic hose or hose-like element. The inner surface 62 of the tube comprises one single guiding element 63, for instance a separate guiding element connected (for instance glued) to the inner surface 62 or a guiding element formed integrally with the tubular element, for carrying a row of containers in a generally helical trajectory.
(42) FIG. 23 shows an alternative embodiment of an assembly according to the invention. The assembly comprises a single guiding element 109 for carrying a row of containers. The single guiding element 109 has a generally helical shape forming a tubular arrangement with a guiding element providing a generally helical trajectory for the containers. In embodiments of the invention the material of the single guiding element is flexible to the extent that it may be unfolded if force is applied to it, but has the tendency to remain in the tubular shape. The tubular arrangement may be sealed, for instance by applying a sleeve around guiding element.
(43) In a further embodiment, not shown in the figures, the tubular assembly comprises a flexible sheet at the inner side of which a number of guiding elements have been formed. The guiding elements are made of relatively stiff, non-flexible material while between individual guiding elements flexible material parts are arranged. Longitudinal edges of the flexible sheet may be connected to each other to form a tubular shape. In disconnected condition the sheet may be unfolded easily. The sheet may also be connected to one or two further sheets (each sheet provided with a number of guiding elements) to form an elongated belt or similar structure that may be easily processed by further processing equipment.
(44) FIGS. 18A and 18B show a further embodiment of the invention. In this embodiment the individual guiding elements 110 have a generally curved shape in cross-section, for instance semi-circular, and are mutually connected, for instance by means of strips 111 of flexible material allowing the guiding elements to be pivoted relative to each other.
(45) FIG. 19 shows an embodiment wherein the tubular assembly 85 comprises a number of guiding elements 15 of the type previously described, for instance in connection with the embodiments of FIGS. 2 and 3. The guiding elements 15 are interconnected using the coupling elements 30. The guiding elements are kept in a substantially tubular arrangement by a tubular element 86, for instance made of (semi-) rigid material. In the shown embodiment an elongated opening 87 is present and therefore the tubular arrangement does not form a fully closed circumference, while in other embodiments (not shown) the tubular element does form a closed circumference. Although the guiding element side walls have been depicted as having a curved side walls, it is evident to the skilled person that differently shaped guiding element parts are also conceivable, for instance in line with the guiding elements of FIGS. 14 and 15.
(46) FIG. 20 is an embodiment comprising s sheet 88 of flexible or rigid material. In the sheet 88 a number of parallel locally weakened areas 89 are provided, for instance by providing lines of perforations 89 in the material of the tube sheet. This makes it possible to tear off pieces 90 of sheet material. Each individual piece of sheet material is formed with one guiding element 78 and therefore the guiding elements may be individualised, for instance when the tubular arrangement has reached its destination. In the figure an optional coupling 84 is shown. This coupling is connected to two opposing longitudinal ends of the sheet 88 and enables the tubular arrangement to be opened easily by opening the coupling 84 (and therefore without needing to tear open the tube). It is evident that this coupling can be dispensed with by replacing it with a suitable line of perforations.
(47) Referring to FIG. 21 an embodiment of an assembly 113 is shown wherein a number of guiding elements 114 (which have not been interconnected directly, for instance via coupling elements) are attached to a sleeve 107. The sleeve, for instance made of thin foil material, has been provided with local weak spots, such as perforations extending in a number of perforation lines 108.
(48) FIG. 22 shows an embodiment wherein the guiding elements 115 have been interconnected to form one single rails. For instance, the guiding elements may be welded together at the connection lines 116. The tubular arrangement may be unfolded by tearing a weld between two neighbouring guiding elements and taking the guiding elements apart.
(49) FIG. 24 is a partly cut-away view of an embodiment of the tubular arrangement of the invention in a further configuration. The embodiment corresponds to the embodiment of FIGS. 5 and 6 and comprises a number of interconnected pivotable guiding elements arranged in a tube-like shape. The tubular arrangement of FIG. 24 comprises the same guiding elements into which a number of containers have been arranged. However, unlike the situation depicted in FIGS. 5 and 6 wherein containers have been arranged in each and every guiding element, in the configuration shown in FIG. 24, containers have been arranged in a subset of all guiding elements only. More specifically, the containers 121a-121f and 122a-122f have been arranged in the six guiding elements 117 and the six guiding elements 119 forming left and right upright walls, respectively. The containers 123a-123f and 124a-124f have been arranged in the six guiding elements 120 and six guiding elements 118 forming upper and lower walls of the tubular arrangement, respectively. In the remaining guiding elements, which are positioned in the four corners of the tubular arrangement, no containers have been arranged. This configuration enables the tubular arrangement to take an essential rectangular cross-sectional shape. Due to the friction between the individual containers, the tubular arrangement is retained in its tubular shape, without a need to provide for any locking means to keep the pivotable guiding elements in position.
(50) The present invention is not limited to the embodiments thereof described herein. The rights sought are defined by the following claims, within the scope of which numerous modifications can be envisaged.
