[0002] Description

[0003] Field of the invention

[0004] The invention relates to an inliner having the features of the preamble of claim 1, a composite package having such an inliner having the features of claim 8, a transport container provided with such an inliner having the features of claim 10 and a method for introducing an inliner into a transport container having the features of claim 12

[0005] State of the art

[0006] Transport containers for the transport of, for example, liquid, pasty or free-flowing goods are made of liquid-tight plastic bodies, which are usually bias-formed. For transport, such transport containers are held upright on a pallet within a grid or a sheet metal casing. So-called intermediate bulk containers (IBCs) are used in industry and trade as an extremely economical and cost-effective means of transport for liquids and, for example, pasty goods. They consist of a stable grid box into which a blow-molded plastic tank container is inserted, equipped with at least one, usually several filling and emptying fittings. These transport containers usually have volumes of 500 or 1000 liters up to 1800 liters or more. For the purposes of these documents, the term “transport container” also includes other transport containers, such as:Transport containers for use in other tank and transport applications, which can be made of stainless steel, for example. In principle, transport containers made of other materials, such as glass or cardboard, can also be used in accordance with the invention.

[0007] IBC transport containers are filled with, for example, paints, pastes, acids, alkalis, oils, and other products from the chemical, food-producing, medical, and pharmaceutical industries for transport to users. They can also be widely used to provide drinking or cleaning water, e.g., in crisis situations or disasters. It is also known to provide a thin-walled, flexible, and, for example, essentially tubular and / or welded film adapted to the inner contour as the inner lining within such a transport container. Such inner linings are called inliners or film inliners; in these documents, they are referred to as "inliners."

[0008] Since transport containers are typically reused and, depending on the application, are contaminated by the contents, it is usually necessary, without an liner, to thoroughly clean the transport container after emptying it before refilling it. This is done manually using pressure and steam jet cleaners or appropriate automatic cleaning systems. The cleaning process is usually very water-intensive and generates a large volume of wastewater, some of which must be treated and disposed of. This cleaning process and the disposal of the washing liquids are very complex and costly and are subject to strict regulations that are constantly being tightened. This cleaning is often carried out at specially equipped stations. This requires transport capacity for the delivery of the contaminated containers and their return transport to the filler.

[0009] Instead of cleaning the transport container, it can be fitted with inliners, which are flexible and conform to the shape of the container, forming a tight inner lining. This inner lining can be removed and recycled after use, or, if contaminated, thermally recycled. Due to the high energy content of the plastics, this thermal reuse is recommended.

[0010] DE 20 2014 105 594 U1 discloses an inner sleeve as an inliner for insertion through an opening in a transport container. The inliner comprises a connection adapter for filling and a connection adapter for emptying. These adapters can be attached in the area of ​​a filling opening and an outlet opening of the transport container. The adapter and inliner form a prefabricated assembly. The inliner is attached to the transport container using connection devices provided on the transport container, in which the adapters are folded over the corresponding threads and then clamped to the closure lids or the emptying fitting.The inner sleeve has a deployment aid which connects two distant sections of the inner sleeve before installation in the liquid container or keeps them at a defined distance from each other and which is designed to detach, open, tear or tear at least on one side when the deployment aid is unfolded within the liquid container. This makes it possible to specifically specify the order in which the inner sleeve is opened. This ensures that a bottom section of the inner sleeve used at the bottom fits against the container without any creases. Freedom from creases is particularly important on the bottom side, as creases there would disrupt the flow from the container. In addition, the inner sleeve is inserted into the container in a folded state. There is a high risk that the inner sleeve will fit against the liquid container in such a way that these original creases are retained.After generating a relative overpressure within the inner liner, it inflates, stretching and smoothing out existing wrinkles. This relative overpressure is caused by sections of the inner liner that do not serve as the base being prevented from unfolding unless the deployment aid is torn or opened. After opening the deployment aid(s), the inner liner can adhere to the container's inner wall, reducing the number of wrinkles.

[0011] EP 2 964 540 B1 discloses a pallet container and a method for folding an inliner into the pallet container. By folding the inliner appropriately, it can be easily inserted into the transport container. Excess gas escaping from the transported goods can be vented via a venting nozzle. A flexible corrugated pipe with numerous lateral holes is also provided in the area of ​​the bottom fitting to improve the residual emptying of the transported goods, allowing the transport container to be emptied almost completely. The pipe is screwed to the filling and discharging fitting on the bottom of the transport container, independently of the inliner.

[0012] A common feature of the current state of the art is that it is currently very complex to equip the transport container with an inner liner so that it fits optimally against the inner walls of the container, preventing excessive creasing of the hollow inner liner. Excessive creasing is detrimental during subsequent filling, as pockets form in the lining, which can place tension on the material and damage the lining, thus leading to leakage of the transported goods. A complete and clean unfolding of the inner lining, and thus the inner liner, in the transport container would therefore be advantageous.

[0013] There are already various solutions for cleaning, but these have always failed because

[0014] - the insertion of the inliner into the IBC is very complex - the inliner cannot be positioned in the IBC (the inliner must be inserted with the inliner base in a rectangular shape exactly corresponding to the IBC inner base for filling, as otherwise bubble spaces will form between the inliner and the inner wall of the outer container during filling, which in turn can promote bursting or tearing of the inliner due to over-tensioning of the film)

[0015] - inflating an inserted inline skate does not bring it into the correct shape

[0016] - because the inliner is not correctly positioned in the bottom area of ​​the IBC, air bubbles are created between the inliner film and the IBC inner wall, which, as previously mentioned, can lead to breakage or tearing of the inliner film in the worst case scenario

[0017] - the liner may burst during removal after emptying and residual contents may contaminate the IBC

[0018] Summary of the invention

[0019] Based on this prior art, the present invention is based on the object of providing an inliner, a composite package, a transport container equipped with an inliner and a method in which an optimal fit of the inliner against the wall of the transport container is ensured, but at the same time an easy insertion for filling and removal after emptying of the inliner is possible.

[0020] This object is achieved by an inliner having the features of claim 1, a composite package having the features of claim 8, a transport container provided with such an inliner having the features of claim 10 and a method having the features of claim 12.

[0021] The aim is to design an inliner, preferably a film inliner, which is inserted into a transport container such as an IBC container before filling and can be clean and, if required, even aseptic or sterile. The inliner should be able to be inserted into the transport container without additional devices or mechanical aids in such a way that it is optimally positioned for filling in the container, namely aligned according to the shape of an inner surface, preferably the inner base, of the transport container. If this alignment is not achieved, significant wrinkles will occur in the wall of the inliner during filling, which can lead to bubbles forming between the inner wall of the IBC transport container and the inliner. As a result, the static weight of the contents is no longer fully absorbed by the transport container and, in the worst case, the inliner could tear.The liner is designed to hold contents and insert them through an opening in the wall of a transport container. The liner is operatively connected to shaped rods that are designed to open with the liner in the transport container, similar to the umbrella principle, when the liner is inserted into the transport container and close when the liner is removed. This advantageously enables oriented placement of the liner in the transport container, preferably at its base, thus eliminating the problems associated with state-of-the-art solutions.

[0022] The mold rods are preferably made of a flexible, resilient material and, due to their inherent stress, can be moved from a deformed position to a rest position, which corresponds to an open position of the liner. Advantageously, the liner and mold rods can be easily inserted and removed through the filling opening of the transport container. In the relaxed rest position, they then assume the desired position in the transport container.

[0023] In a preferred embodiment, the inliner features fixing elements to which the molded rods can be secured. This advantageously creates the desired operative connection, allowing the molded rods to be positioned precisely in any position.

[0024] Preferably, the liner is provided with at least two shaped rods, which, in the rest position, overlap at least one point and span a surface, at the corners of which the fixing elements are provided. Advantageously, this allows a surface adapted to the respective transport container or at least one of its inner surfaces to be stretched and reliably covered.

[0025] In a preferred embodiment, the clamped surface covers an inner surface, preferably a bottom surface, of the transport container, thereby advantageously counteracting the formation of wrinkles and covering them completely. This advantageously counteracts potential damage to the liner when filling with contents.

[0026] The shaped rods are preferably fiberglass rods, which advantageously possess the desired properties and the residual stress required to assume a predetermined position in their initial state. However, other materials with corresponding properties can also be used. The shaped rods are preferably made of inexpensive and / or recyclable materials to keep the costs of the liner low.

[0027] In a preferred embodiment, the liner and mold rods can be accommodated in their deformed position in an application hose whose outer cross-sectional dimensions are smaller than the filling opening of the transport container. This advantageously allows the liner to be easily inserted manually into the transport container.

[0028] The object is also achieved by a composite package, designed for introducing an inliner through an opening in a container wall of a transport container, comprising

[0029] - an inliner equipped with molding rods, as already described,

[0030] - an application hose in which the inliner and the forming rods can be accommodated in their deformed position and whose external dimensions in cross-section are smaller than a filling opening of the transport container,

[0031] Advantageously, this composite package enables a prefabricated solution that makes it easier for the user to place the inliner in the transport container while ensuring that the transport container is not contaminated.

[0032] In a preferred embodiment, the composite package additionally comprises a molded part designed to secure the liner to the filling opening of the transport container after it has been inserted into the container. Preferably, the molded part has air holes. This advantageously ensures that the liner can be filled without problems, while at the same time allowing air displaced in the transport container to escape easily.

[0033] The above-mentioned task is also solved by a transport container equipped with an inliner as described above.

[0034] Preferably, the transport container is designed such that it has a filling opening and, if appropriate, an outlet opening, and is provided with the inliner arranged in the transport container, wherein the inliner can be secured to the filling opening. This advantageously makes it possible to ensure filling or emptying without the inliner slipping and thus also without contamination of the transport container. The stated object is also achieved by a method for introducing an inliner into a transport container through an opening in a container wall of the transport container, which method comprises the steps:

[0035] - Creating an effective connection between the form rods and the inliner,

[0036] - Transferring the shaped rods into a deformed, resilient position by inserting the shaped rods and inliner into an application hose,

[0037] - Inserting the application hose with the inliners and molding rods contained therein through a filling opening into the transport container,

[0038] - Pulling off the application hose and releasing the molding rods, which thereby stretch the inliner and move into their rest position on a floor surface of the transport container,

[0039] - optional filling of the inliner in the transport container with filling material.

[0040] Advantageously, the transport container can easily be provided with the inliner in such a way that contamination of the transport container is reliably avoided.

[0041] To empty the inliner in the transport container, the following steps are preferably carried out:

[0042] - Removal of the filling material, preferably by pumping, suctioning using a suction lance and suction pump through the filling opening or emptying through a valve, if necessary down to a residual amount of filling material,

[0043] - Pulling the inliner upwards to form a sump, preferably above the forming rods,

[0044] - Removal, preferably by pumping through a suction lance, of filling material from the sump,

[0045] - Remove the inliner from the transport container.

[0046] By pulling on the inliner and suctioning / pumping it out, e.g. using a special suction lance, it can be ensured that even residual quantities can be removed as far as possible before the inliner is taken out of the transport container, so that the emptied inliner can be easily removed by hand or with a pull-out device through the filling opening.

[0047] For the emptying process, the liner should be able to be emptied almost completely, down to minimal residue, either by suction or by emptying, for example, through a valve on the transport container. Afterward, the liner contaminated by the contents should be easily removed by the user for disposal. The liner should not be damaged during removal, as damage could cause any remaining residue to flow out of the liner, thereby contaminating the transport container.

[0065] Before describing the invention in detail, it should be noted that it is not limited to the specific components of the device and the specific method steps, as these components and methods may vary. The terms used herein are intended solely to describe particular embodiments and are not intended to be limiting. Furthermore, when the singular or indefinite articles are used in the description or claims, this also refers to the plural of these elements, unless the overall context clearly indicates otherwise.

[0066] When reference is made to “filling goods” 40 in these documents, this refers in particular to liquid, pasty or free-flowing transport goods with which transport containers such as IBC containers are filled for the transport of these goods.

[0067] Such a transport container 12 is shown in Fig. 6. In the exemplary embodiment, it is an IBC container, which, as explained above, comprises a bias-formed transport container 12 accommodated in a wire mesh. In principle, such a transport container can be made of plastic or metal, such as stainless steel. Other materials can also be used according to the invention, such as glass or cardboard, such as cardboard boxes made of heavy-duty corrugated cardboard.

[0068] To protect the transport container from contamination, an inliner 10 is incorporated in this transport container 12 in the exemplary embodiments.

[0069] According to Fig. 1, the inliner W, which is preferably made of a film but can also be made of other suitable materials, is preformed by welds and folding so that the shape of the inliner 10, when opened, can adapt as closely as possible to the interior shape of an IBC container or other possible transport container. The filling area 10a of the inliner 10 at the top is welded into a funnel shape to facilitate filling.

[0070] As shown in Fig. 2, forming rods 14 are attached to this inliner, which can be equipped with single or multiple layers. In the foreground, the base 10b of the inliner 10 is visible with flexible forming rods 14 attached to fixing elements 10c. These are preferably made of fiberglass or a flexible plastic or metal or another flexible material. The fixing elements 10c firmly connect the forming rods 14 to the base 10b of the inliner 10. In principle, any other form of connection of the forming rods 14 to the base 10b is possible, e.g. gluing or welding into the film. In expanded form, the forming rods 14 stretch the base 10b of the inliner 10 into a preferably rectangular shape, for example, which corresponds to an inner surface, preferably the inner base, of the transport container 12.The shaped rods are preferably fixed in the base area, but can also be fixed at any other suitable location on the inliner that serves the intended purpose.

[0071] These shaped rods 14 are preferably fixed crosswise inside or outside to the base 10b, e.g., using plastic pads that can be glued, welded, or clipped to the inliner's film. The fixing elements 10c, in turn, fix the shaped rods 14 so that they rest spread apart on the base 10b. The spread shaped rods 14 are grasped by the fixing elements 10c and brought toward each other so that they are bent and meet at the ends. Since the inliner film is fixed to the fixing elements 10c, it is automatically moved along and pre-folded. This gives the inliner 10 a centered shape.

[0072] As shown in Fig. 3, the forming rods 14, due to their flexible properties, can be bent under residual stress in such a way that they allow the entire inliner 10 to be folded into a very slim shape. By connecting the forming rods 14 to the bottom film of the inliner at the fixing elements 10c, they expand, as soon as they return to their resting or initial position, to a flat shape that follows the shape of the inner base.

[0073] In principle, the inliner 10 is operatively connected to the molding rods 14 in such a way that the inliner 10 opens in the transport container 12, similar to an umbrella principle, with the molding rods 14 when the inliner is inserted into the transport container and closes when the inliner is removed. The molding rods preferably move to their rest position upon opening and into a deformed position upon closing by pulling out the emptied inliner.

[0074] The shaped rods 14 also assume this "deformed" position when inserted into the inliner 10, as they are accommodated in an application hose 16 in the deformed state. "Deformed" means that the shaped rods 14 are preferably made of a resilient material - e.g., they are fiberglass rods that are highly elastically deformable. The shaped rods 14 are inserted into the inliner in a pre-tensioned state and released there to relax their tension. For example, the shaped rods can be bent into a semicircle and are thus tensioned. The application hose 16 then holds the rods in this pre-tensioned position until it is removed.

[0075] The filling opening 12a of the transport container 12 is generally dimensionally limited, so that the inliner 10 has to be folded to the diameter of the filling opening 12a in order to be able to insert it through the filling opening 12a of the transport container 12. In order to prevent the inliner 10 from expanding after production and before it is inserted into the transport container 12, the folded inliner 10 together with the forming rods 14 is held in the folded shape by an application hose 16 pulled over it, as shown in Figs. 4 and 5. The inliner and the forming rods 14 are designed in their deformed position to be received in the application hose 16. The outer dimensions of the application hose 16 are smaller than the filling opening 12a of the transport container 12. Specifically, the application hose 16 is smaller than the cross-section orDiameter of the filling opening 12a of the transport container 12, so that the inliner 10 can be inserted in folded form through the filling opening 12a. As a transport safeguard and simultaneous insertion aid, the application hose 16 completely encloses the folded inliner 10 and also holds the folded, tensioned forming rods 14 in a deformed position retracted into the application hose so that the inliner 10 can be inserted through the filling opening 12a of the transport container 12.

[0076] Preferably, an insertion funnel 42 as shown in Fig. 6a can be attached to the filling opening 12a of the transport container 12. This advantageously simplifies the insertion of the folded inliner with application hose 16, and at the same time, the application hose can be secured to stud bolts 44 attached to the insertion funnel 42, so that the application hose 16 can be removed simply by pressing in the entire inliner package. At the same time, the insertion funnel 42 serves as protection against sharp edges in the filling opening 12a of the transport container. However, insertion is also possible without such an insertion funnel.

[0077] The inliner 10, which is fixed in its folded form in this position by the application hose 16, is first pushed through the filling opening 12a of the transport container 12 together with the application hose 16 as shown in Fig. 6 and then introduced further into the transport container. The application hose 16 is pulled off outside the filling opening 12a of the transport container 12 as shown in Fig. 7, preferably upwards and out of the transport container 12. As a result, the flexible forming rods 14 are released from the shape predetermined by the application hose and expand outwards into their originally unbent shape. In doing so, due to their fixation, for example at the base 10b of the inliner 10, they pull the inliner outwards due to their inherent tension. This results in a flat basic shape, in the exemplary embodiment a flat base shape, for the inliner which follows the shape of the transport container 12.

[0078] Since the forming rods 14 do not always open completely on their own, especially after long storage in the application hose 16, it is advisable to pull the stretched inliner upwards a few times at the filling area through the filling opening 12a and then let it sink back down towards the bottom of the transport container 12. Due to the up and down movement, an air cushion forms under the inliner base stretched by the forming rods 14, which escapes upwards laterally around the base and thus spreads the inliner base even better in the transport container 12.

[0079] According to Fig. 8, the bottom 10b of the inliner 10 is drawn into a flat shape by the thus expanded mold rods 14, which corresponds, for example, to the shape of the inner bottom of the transport container 12. As a result, it lies flat on the inner bottom of the transport container 12 or against another surface of the transport container.

[0080] The funnel-shaped filling area 10a of the inliner 10 protrudes upward through the filling opening 12a of the transport container 12. A molded part 18 is pulled over this area as shown in Fig. 9. This molded part 18 allows the funnel-shaped filling area 10a of the inliner 10 to be secured during the filling process by means of a clamp 20 to prevent it from slipping into the transport container 12. At the same time, the molded part 18 allows the air displaced from the transport container 12 during filling of the inliner 10 to escape safely to the outside through air holes 18a.

[0081] The filling area 10a of the inliner 10 is secured in the molded part 18 according to Fig. 10 by means of a clamp 20 against slipping into the transport container 12.

[0082] The liner can now be filled with filling material as shown in Fig. 11. As the filling material 40 rises, it opens upwards into the transport container 12, starting from the bottom area, to line the container. It adheres tightly and precisely to the inner walls of the transport container 12. After filling, the filling area 10a of the liner 10 is closed, e.g., with a cable tie or a suitable tying material, and folded inward into the transport container 12. For safe transport, the transport container 12 can be closed with the original lids 22 at the top of the filling opening 12a and at the bottom of the valve 24 as shown in Fig. 13.

[0083] For emptying, according to Fig. 14, the liquid in the inliner 10 is sucked out from above through the filling opening 12a of the transport container 12 and the filling area 10a of the inliner 10. In this process, as much liquid as possible is sucked out of the inliner 10, except for a residual amount in the bottom area. In order to concentrate this liquid in the middle, like in a sump 38, the inliner 10 is pulled upwards at the filling area 10a, so that a sump-like tub is formed (Fig. 15). The residual amount can now be sucked out. Preferably, a rigid suction lance with a small filter basket should be used for this purpose. This allows almost all of the liquid to be removed without the inliner becoming stuck to the suction lance. Once all of the liquid has been sucked out, except for a small residual amount, the suction lance or suction hose is removed.

[0084] Now, according to Fig. 17, the inliner 10 is pulled upwards in the direction of the arrow, whereby the flexible shaped rods 14 bend into a U-shape due to the contact with the filling opening 12a of the transport container and the pull, so that they can be pulled upwards and outwards together with the inliner 10, e.g. by pulling with a loop belt 26 wound around the upper area of ​​the inliner 10, which is pulled upwards by the fork of a forklift truck or by another lifting device.

[0085] When removed manually, the inliner 10 is pulled upwards on any side until one of the molding rods 14 with fixing elements 10c is visible in the filling opening 12a of the transport container 12. This first molding rod is pulled out first with one of its fixing elements 10c, followed by the film of the inliner 10, and then, piece by piece, the other ends of the two molding rods 14 with fixing elements 10c, which were previously located inside the transport container 12, are pulled out.

[0086] If there is still a small amount of residue in the inliner 10, it can be removed as shown in Fig.

[0087] 18, for example, can be swung over a tray 28 and cut open there, e.g., with a utility knife, so that the remaining amount can flow out and the liner can then be sent for thermal recycling. A new liner is then inserted into the now empty transport container 12.

[0088] The transport container can now be re-equipped with an inliner for the next filling.

[0089] The inliner 10 equipped with the shaped rods 14, together with the application hose 16, in which the inliner 10 and the shaped rods 14 can be accommodated in their deformed position and whose external dimensions are smaller than a filling opening 12a of the transport container 12, forms a composite package designed for inserting an inliner 10 through an opening in a container wall of a transport container 12. It can be made available in this form to users of such transport containers and is readily and easily deployed.

[0090] Likewise, the composite package can additionally comprise the molded part 18 in order to fix the inliner 10 to the filling opening 12a of the transport container 12 after it has been introduced into the transport container 12, wherein the molded part 18 preferably has air holes 18a.

[0091] On a transport container 12, which has a filling opening 12a and optionally an outlet opening 36 and is provided with the inliner 10 arranged in the transport container 12, the inliner 10 can preferably be fixed to the filling opening 12a.
