Definitions

  • the invention relates to a transport container for food products and a method for transporting food products, wherein a tank is used.
  • the conventional tanks have even more disadvantages.
  • the tank emptied by the user must be cleaned after returning to the manufacturer. This can be very complicated, in particular due to product adhesion to the inner walls of the tank.
  • the tanks must be regularly checked for their functionality, for example, the tightness of the tank must be checked because a leaking tank not only product can escape, but may also occur in the penetration of contaminated air product contamination.
  • a transport container thus comprises a tank and an inliner arranged to be interchangeable in the tank for receiving the product.
  • transport containers which are used for transporting between the manufacturer of a food product and the processor or distributor.
  • transport containers for the transport of food ingredients, such as fruit or fruit pieces, used.
  • transport containers are preferably reusable transport containers, not disposable packages, such as bag-in-box packages, used for retail sale of wine or fruit juices and not intended for recycling.
  • the tank is formed Favor dimensionally stable, while the inliner is flexible and in the empty state a much smaller volume claims than the tank. When filling then increases the volume of the inliner, which then applies to the inner wall of the tank.
  • the tank can be designed so that the inliner can be switched into or out of the tank. After use of the inliner, so after emptying, thus the inliner can be quickly and easily removed from the transport container and a new inliner just as easily be introduced into the tank.
  • the tank may have a tapered, in particular funnel-shaped, outlet arranged in the lower region of the tank, the outlet opening of which is arranged eccentrically.
  • eccentric means here that the outlet opening is not centrally located at the bottom of the tank, but is arranged to the edge in the direction of the side wall of the tank.
  • the outlet opening can be aligned substantially vertically when the tank is stationary. This additionally facilitates the handling for the user and enables a simplified docking of a filling or emptying device from the side.
  • the outlet opening with a sufficiently large diameter, so that a human hand can reach through, preferably with a diameter of at least 10 cm, more preferably with a diameter of 12 to 16 cm, be formed.
  • a large spout allows the user to reach into the tank in order to align an in-tank in-line liner so that it can be safely filled.
  • the outlet opening can be chosen so large that the inliner can be introduced via this into the tank.
  • the tank can continue to have at least one viewing window, in particular at the outlet.
  • the viewing window the user has the opportunity to check whether the inliner unfolds during filling and applies as wrinkle-free as possible to the inner wall of the tank. When emptying can also be easily checked whether the liner was completely emptied.
  • the tank may have a retainer device, preferably in the upper half, more preferably on the cover, which serves to hold the inliner in the tank.
  • a retainer device preferably in the upper half, more preferably on the cover, which serves to hold the inliner in the tank.
  • the tank may have a lid with a closable opening for passing an inliner.
  • the inliner is inserted from above through the opening into the tank and the area over which the product is introduced into the inliner is aligned with the outlet opening, thanks to the large outlet opening through which the user can reach into the tank.
  • the tank may have a bottom with a closable opening for passing an inliner, wherein at least a part of the outlet may be provided on the closure of the opening.
  • the inliner is introduced by removing the lid or opening the lid in the tank and then the inliner can be aligned with the outlet opening of the outlet.
  • the inliner may have an outlet connection, wherein a closure device, in particular a membrane or rupture disk, is provided on the outlet connection for sterilizing the inner surface of the inliner.
  • a closure device in particular a membrane or rupture disk
  • a membrane or rupture disk has proven to be particularly advantageous, since these can be pierced or broken through themselves during filling by the food product, so that the interior of the inliner is protected from environmental influences until the last moment. Thus, a sufficient hygiene can be guaranteed especially for sterile food ingredients.
  • the outlet nozzle may have a smaller outer diameter than the outlet opening of the tank. This is particularly useful when the liner is inserted through the opening in the lid or in the ground, since then the outlet nozzle must be brought from the inside to the outlet opening of the outlet. Through the large outlet opening, the user can reach into the tank, take the spout in his hand and then bring it to the outlet opening.
  • a centering disc can be used to center the outlet nozzle in the outlet opening of the tank. Since the outlet nozzle has a smaller outer diameter, it is ensured by means of the centering that the outlet nozzle is seated at its intended position and can not occur during filling or emptying by displacements of the outlet nozzle voltages on the liner, which lead in the worst case to a rupture of the liner could.
  • the centering is made possible by a positive connection between centering and outlet.
  • the centering disc may be formed integrally with the outlet nozzle.
  • an inliner is completely inserted through the outlet opening, i. H. a closable opening in the bottom or in the lid is not necessary.
  • the outlet nozzle can be correctly positioned with the centering disc.
  • an opening in the centering disc for receiving the outlet nozzle may be arranged eccentrically. Since the outlet opening has a larger outer diameter than the outlet nozzle, it is advantageous if the opening is arranged eccentrically in the centering, so that the outlet nozzle of the inliner can be arranged as far down the outlet opening, whereby a complete emptying of the inliner is promoted ,
  • a part of the outlet nozzle of the tank may project outwardly from the centering disk. At this part of the outlet nozzle can then be directly or indirectly attached to a filling or emptying device.
  • a valve device may be placed on the protruding part of the outer nozzle.
  • a conventional valve device such as are present on conventional tanks, standard filling / emptying devices can be used without having to provide further adapters.
  • At least one seal can lie in the mounted state between outlet nozzle and valve device. This prevents leakage of the food product.
  • a fastening means for securing the outlet nozzle may be provided at the outlet opening.
  • the fastening means can fix the outlet nozzle against rotation at the outlet opening. This measure prevents tensions when filling or emptying the inliner, which in the worst case could lead to cracks in the inliner.
  • the fastening means can also fasten the valve device sealingly on the outlet connection.
  • the fastening means can also fasten the valve device sealingly on the outlet connection.
  • the inliner may have an overpressure safety device, in particular a rupture disk or a safety valve, preferably a pressure relief valve.
  • an overpressure safety device in particular a rupture disk or a safety valve, preferably a pressure relief valve.
  • the overpressure assurance means may communicate with the outside of the tank. This ensures that in case of overfilling escaping food product does not pollute the inside of the tank. A cleaning of the inside is much more complex than a cleaning of the outside of the tank. Moreover, when the food product exits via the overpressure safety means, it is easily recognized that the filling of the inliner must be completed.
  • the inliner may include a support means for securing the inliner to the tank, especially in the upper half of the tank.
  • the inliner can be arranged hanging in the tank, whereby a possible wrinkle-free application is made possible on the inner wall of the tank.
  • the overpressure safety means may be provided on the holding means.
  • the overpressure safety means together with the holding means must be attached to the inliner next to the outlet connection only at a second location. This optimizes the production of the inliner.
  • the invention also relates to an inliner for use in a transport container as described above.
  • the inliner according to the invention is made of a food-compatible plastic film, in particular polypropylene or polyethylene, with a sterilized outlet nozzle. Since the transport container according to the invention gets its stability from the tank, one does not need a dimensionally stable material for receiving the food product, but can use conventional plastics which are suitable for transporting food. Furthermore, since the food product is transported within the potion, no additional light protection, such as aluminum foil, is needed on the liner. Preferably, therefore, the liner can only be made of plastic.
  • the outlet nozzle may have a closure device, in particular a membrane or rupture disk for sterilizing the inner surface of the inliner.
  • a membrane or rupture disk has proven to be particularly advantageous, since these can be pierced or broken through themselves during filling by the food product, so that the interior of the inliner is protected from environmental influences until the last moment. Thus, a sufficient hygiene can be guaranteed especially for sterile food ingredients.
  • the membrane or the rupture disk can preferably be designed so that it breaks free of fats under a predetermined pressure load. This prevents that fragments of the membrane or the rupture disk can get into the inliner and so can contaminate the food product.
  • the membrane or rupture disk can also be additionally configured such that the membrane or the rupture disk parts can not overlap when the inliner is emptied. Thus, obstruction of the emptying can be prevented.
  • the inliner may have an overflow protection means, in particular a rupture disk or a safety valve, preferably a pressure relief valve.
  • an overflow protection means in particular a rupture disk or a safety valve, preferably a pressure relief valve.
  • a retaining means may be provided for securing the liner within a tank.
  • the holding means if necessary together with a Holding device of the tank, the inliner can be arranged hanging in the tank, whereby a possible wrinkle-free application to the inner wall of the tank is made possible.
  • a marking can be provided on the holding means and / or overpressure securing means, indicating the orientation under which the inliner is to be introduced into the tank of the transport container with respect to the orientation of the outlet opening, so that after insertion of the inliner the outlet nozzle at the outlet opening lies. If the inliner is inserted from above into the tank, the user can recognize thanks to the marking for which orientation of the inliner the outlet nozzle in the lower area of the tank is opposite to the outlet opening. This prevents the inliner from being twisted or knotted inside the tank, which allows the most wrinkle-free filling possible.
  • the empty liner can be folded so that the inliner wrinkle-free on the inner wall of the tank when filling with the food product.
  • a Z-shaped fold has shown that the inliner can create as wrinkle-free as possible on the inner wall of the tank.
  • At least one adhesive strip or at least one rubber band can be arranged on the folded inliner, depending on the filling level, to deploy the inliner only partially. If the product runs into the inliner, the area unfolds first, which is not held together by adhesive strips or rubber bands. This results in the inliner first settling at the bottom of the tank before the liquid rises, which in turn limits the appearance of wrinkles.
  • the overpressure protection system and / or the holding means may be made of a weldable plastic. These can thus be produced cheaply and disinfected by irradiation.
  • the invention also relates to a tank for use in a transport container as described above.
  • the tank according to the invention comprises a tapering, in particular a funnel-shaped outlet arranged in the lower region of the tank, whose outlet opening is arranged eccentrically. Thanks to the eccentric outlet opening, as described above, access to the inliner is simplified. This allows the inliner in the transport container to be easily aligned with the outlet opening.
  • the funnel-shaped outlet also makes it possible to emptying the inliner as completely as possible.
  • the tank may have at least one device for venting and / or venting. Since filling the inliner food product, the corresponding volume must be able to escape from the tank. This is done with a venting device. Likewise, a device for venting is provided for emptying to avoid a vacuum formation.
  • the invention also relates to a method for transporting food products in a transport container, which is characterized in that the food product is transported in an inliner arranged interchangeably in the interior of a tank.
  • the food product is no longer filled directly into the tank, but is located in an in-tank in-tank, eliminating the time and energy-consuming sterilization of the interior of the tank.
  • the used inliner is replaced by a new inliner, which also eliminates a costly cleaning.
  • the invention further relates to a method for preparing a filling or emptying of a transport container as described above, wherein at the outlet connection of the inliner a connecting piece is connected, which serves to connect a filling or emptying device, characterized in that before connecting a filling or emptying device, the area is disinfected from the connector to the closure device of the outlet nozzle.
  • a cold disinfection is carried out here by spraying a disinfectant solution.
  • the connector may be the valve device, wherein a disinfectant is introduced through the open valve device in a gap between the valve device and closure device and then the valve device is closed, so that remains until filling or emptying of the disinfectant in the space.
  • a disinfectant is introduced through the open valve device in a gap between the valve device and closure device and then the valve device is closed, so that remains until filling or emptying of the disinfectant in the space.
  • the invention further relates to a method for filling a transport container, as described above, comprising the steps of docking a filling device, venting the space between the inliner and the tank and filling the inliner via the outlet connection of the inliner.
  • the invention also relates to a method for emptying a transport container, as described above, comprising the steps of: docking an emptying device, ventilating the space between the inliner and the tank and emptying the inliner via the outlet nozzle of the inliner.

  • the lid portion 9 of the tank 3 does not need to be modified, and the liner 31 could be inserted into the outlet 7 with the bottom portion removed.
  • Fig. 3b shows an exploded cross-sectional view of the lower portion of the tank 3 of Fig. 3a.
  • Fig. 3b illustrates how the spout 33 of the liner 31 is passed from the interior of the tank 3 through the outlet opening 15 to secure the inliner 31 at the bottom of the tank 3 at the outlet opening 15.
  • the outlet opening 15 is larger in cross-section than the outside diameter of the outlet nozzle 33.
  • the outlet opening 15 is designed such that a user of the transport container 1 grips the inside of the tank with his hand in order to grip the outlet nozzle 33 can and pull through the outlet opening 15 therethrough.
  • the outlet opening 15 has a diameter of at least 10 cm, and is preferably in a range of 12 cm to 16 cm.
  • the outlet nozzle 33 is centered in the outlet opening 15 by a centering disk 47, preferably in a form-fitting manner.
  • the passage opening 49 of the centering disk 47 is formed eccentrically, so that the outlet nozzle 33 is located as close as possible to the lower edge 51 of the outlet opening 15. This facilitates the emptying of the liner 31, since in a stationary transport container 1, the outlet nozzle 33 is thus arranged as far down as possible.
  • the outlet nozzle 33 and the centering disk 47 may also be formed in one piece.
  • valve device 17 When plugged in, part of the outlet connection piece 33 protrudes from the inside of the tank and projects outwards from the centering disk 47. In this projecting part, in which the seal 37 is located, then the valve device 17 will create a sealing.
  • a valve device 17 for example, a flap valve with a flap 53rd used.
  • a filling or emptying device can be connected via a connecting thread 55.
  • the attachment of the outlet nozzle 33 at the outlet 7 should be possible against rotation, therefore, for example, a bayonet between the flange 57 and the centering 47 is suitable.
  • the valve device 17 can be fastened by means of a clamp closure either on the centering disk 47 or on the connection flange 57.
  • the gap between the flap 53 and the closure device 35 of the liner 31 is also cleaned or sterilized according to the product requirements.
  • a disinfectant can be sprayed into this intermediate space, which then remains in the intermediate space after closing the valve device 17 and is removed from the intermediate space only when it is filled or emptied.
  • FIG. 3c shows an exploded cross-sectional view of the upper portion of the tank 3 of Fig. 3a.
  • FIG. 3 c illustrates how the holding means in the lid region 9 of the transport container 1 fixes the inliner 31 on the tank 3.
  • the holding means 25 is inserted through the opening in the closure 11 and secured by a union nut 27 on the closure 11 against rotation.
  • the attachment is sealing to prevent leakage of the food product in the event of bursting of the liner 31.
  • the closure 11 is sealingly attached to the lid 9. Again, a bayonet closure is advantageous to prevent unwanted twists of the liner 31.
  • valves 21 and 23 may also be arranged on the closure 11.
  • Fig. 4 shows schematically the transport container 1 according to the invention with a filled inliner 31 in cross section.
  • the inliner 31 abuts against the inner walls of the tank 3, including the lid portion 9 and the spout 7.
  • the spout 33 is connected to the valve device 17 attached via the centering disk 47 on the connection flange 57 on the tank 3.
  • the holding means 25 is fastened to the closure 11, which in turn closes the opening in the lid region 9.
  • the inliner 31 has taken on the shape of the tank 3 in the filled state and is wrinkle-free against the inner wall of the tank 3.
  • transport container 1 for transporting food products, in particular sterile foodstuffs, will be described below.
  • step S1 the closure 11 is removed from the lid portion 9 of the tank 3. Thereafter, in step S2, the holding means 25 is guided through the opening in the closure 11 from the inside to the outside and with the help of the union nut 27 on the closure 11 sealingly attached. Then, in step S3, the inliner 31 is freely floated from above into the tank 3. It is important to ensure that the mark 46 is aligned so that the outlet nozzle 33 of the outlet opening 15 is opposite. This means that the inliner 31 just hangs in the installed state in the tank 3 and no tensions occur during filling. In step S4, the closure 11 is then secured against rotation on the lid 9 with the bayonet closure.
  • step S5 the outlet pipe 33 is pulled out through the outlet opening 15 of the tank 3 in step S5. Since the outlet opening 15 is formed large enough, can be handed by hand into the tank 3, the outlet nozzle 33 is taken and brought to the outlet opening. In step S6 then the outlet nozzle 33 is centered with the centering disk 47 in the outlet opening 15. With the bayonet lock, the outlet nozzle 33, which is arranged in a form-fitting manner in the centering disk 47, can then be secured against rotation on the connection flange 57 (step S7).
  • valve device 17 is placed on the outlet pipe 33 (step S8).
  • the valve device 17, for example a flapper valve, is then fastened by means of a clamp closure to the discharge nozzle 33, the centering disk 47 or the connecting flange 57 (step S9).
  • step S10 the interior space between the valve device 17 and closure device 35 is disinfected with a suitable disinfecting solution through the opened valve 17. This can be done for example by spraying the solution. So that the disinfectant solution does not leak, then the valve device 17 is closed.
  • a blind cover can be screwed onto the connecting thread 55 of the valve device 17 until further use.
  • step S20 the blind cover screwed onto the connecting thread 55 is removed. Thereafter, a filling device is docked to the connecting thread 55 in step S21. So that when filling the inliner 31, the pressure in the tank 3 can not rise excessively, the tank 3 is vented by means of the valve 21, 23 (S22).
  • the structure is then damped.
  • the disinfectant solution in the space between the valve device and shutter 35 should mitverdampfen to additionally sterilize the air space in the space (step S23). After this step, a germ-free environment in the transport container 1 is ensured.
  • step S24 the flap 53 of the valve device 17 is then opened and the food product enters into the interior of the inliner 31 after the closure device 35 has been broken through.
  • the inliner 31 then fills in step S25. In this case, the filling through the viewing window 13 can be observed and monitored. Thanks to the incoming product volume, the inliner 31 opens and deposits evenly on the inner wall of the tank 3. In this case, only the bottom area is filled, since the rubber band 46 prevents the rising of the liner 31 further up the beginning.
  • valve device 17 After entry of the desired product volume, the valve device 17 is then closed again and the filling device is removed (step S26).
  • a small amount of gas can be injected into the inliner with the aid of a gas pressure surge, for example with nitrogen, so that it already engages against the inner wall before filling.
  • the amount of gas should be adjusted so that after filling the safety valve 39 remains closed.
  • the filled transport container 1 can now be loaded and the food product, which is now in the inliner inside the tank, can be transported safely and under sterile conditions to the consumer.
  • step S30 a dummy cover applied on the connecting thread 55 is removed. Thereafter, the emptying device is docked in step S31. It is important to ensure that the area between the emptying device and valve device 17 is disinfected. You can use the same procedure as when filling the tank 3.
  • step S32 the tank 3 is then vented via the valve 21, 23. This can possibly also be done by adding gas, in particular nitrogen.
  • gas in particular nitrogen.
  • the flap 53 of the valve device 17 is opened and the food product pumped by means of a pump through the emptying device (step S34).
  • step S35 the emptying device is removed and again the blind cover is rotated onto the thread 55. Now the transport container 1 returned together with the used inliner 31 to the manufacturer of the food product.
  • the used inliner 31 is taken out of the tank 1 again. Before removing it may be determined by weighing, if there is still a residual amount in the liner 31. If this amount is too large, it must be pumped out before removing the liner 31. For this purpose, the procedure described in FIG. 7 is followed. Thereafter, the valve device 17 is then removed from the outlet pipe 33, and possibly a cap placed on the connecting piece 33, to prevent any remaining product residues flow out. Similarly, the closure 11 is removed from the lid portion 9 of the tank 3 and the union nut 27 unscrewed. Then, the liner 31 can be removed from the tank 3 and disposed of. The valve device 17 is cleaned and stored in a disinfecting bath. The tank 3, if dirty, also cleaned.
  • the tank 3 and the inliner 31 and the described method it is now no longer necessary to clean the interior of the transport tank on return.
  • the use of the inliner, which is removed after use, also the emptying of the transport container is substantially simplified and adhesion of the product to the interior of the tank 3 no longer occurs.
  • tanks 3 can be used longer and need less maintenance. By eliminating the time-consuming cleaning process, the tank can also be used more quickly.
