Definitions
- the present invention relates to a method and a device for filling containers as well as to a container which can be filled with the described method.
- a variety of devices and methods for filling containers is known.
- the empty containers for example plastic containers, are filled with a liquid, for example a beverage, during a movement along a transport path.
- a wide variety of variants are known, for example, a hot filling of drinks or a filling of drinks with different components.
- the container is filled via an orifice of the container and an inner volume of the container increases during the volume.
- the inner volume of the subsequently filled container is at least twice (preferably at least three times, preferably at least five times and particularly preferably at least ten times) the volume of the unfilled container.
- the container itself increases in the context of the filling process. However, this enlargement does not refer to any occurring slight enlargement, which occurs as a result of the filled contents. Rather, it is proposed that a substantial increase in volume of the container, in particular just by the filling process occurs. In a sense, therefore, the container is "inflated" directly by the filling material to be filled.
- the container is or was expanded prior to the filling process by an expansion process.
- a plastic preform is first expanded into a plastic container and then advantageously this plastic container thus produced is again reduced in volume, in particular folded, and preferably subsequently expanded again through the filling process.
- the container to be filled (next to its mouth) already has its final shape in at least one region of the container, for example in a bottom region.
- This expansion process can take place immediately before filling, but it would also be conceivable that the containers are first reduced in their volume after their production and then stored in this reduced state and / or to a bottler be transported.
- the container is compressed after the expansion process. It is thus possible in particular for the container produced by the expansion process to be folded in such a way that its internal volume is reduced.
- the folded state is preferably a predetermined wall section and in particular a circumferential wall section adjacent to another predetermined wall section and in particular a further circumferential wall section.
- these wall sections in a folded state of the containers at least partially and preferably along a circumferential surface.
- a container is produced by means of a blow molding machine and this container is subsequently rolled up or folded in order to reduce the inner volume of this container as far as possible in this way.
- the container is folded with respect to a defined folding edge.
- This is preferably a folding edge running around with respect to the longitudinal direction of the container, and particularly preferably a folding edge extending at least in sections and particularly preferably in a completely straight line.
- the container is folded so that the folded container can be inserted into another, correspondingly folded, container. It is thus possible that two or more containers, in particular in a cylindrical region thereof, are inserted into one another.
- the container is rolled in the context of the folding process.
- a folded or rolled-up container shape has in this way two concentric outer diameters, which preferably lie one above the other.
- the rolled-up container shape has a concentric inner diameter or a further concentric inner diameter, which is smaller than a smaller outer diameter.
- the wall of the container has a thickness which is between 0.1 and 0.8 mm, between 0.2 and 0.6 mm and particularly preferred between 0.3 and 0.45 mm.
- the container is pressure-stable for example carbonated drinks such as beer or soft drinks.
- the container is folded or rolled in such a way that a volume ratio between the plastic preform and the volume-reduced container (which are inserted into one another) is smaller than 1: 2, preferably 1: 1, 5 and particularly preferably less than 1: 1 .
- this is a volume ratio between the plastic preform and the unrolled container in the case of a 20-liter container at 1:50.
- compression of the material preferably also occurs, which is preferably permanent.
- this deformation is still present even after filling under pressure.
- the container is deformed in a cold state and in particular without thermal action. This may mean that, for example, the plastic preforms are cooled to plastic containers after they have been formed, before they are compressed or folded. However, it may also be sufficient to heat the molded plastic containers just not further.
- two or more such compressed containers are then stacked one inside the other.
- a transport of the stacked containers is easily possible.
- the containers can be separated again and then be filled in particular with a liquid.
- At least one wall section of the container which is at a distance from the mouth of the container has substantially the same wall thickness before the filling operation as after the filling process.
- the container is not heated during the filling process or only to a temperature which is below the temperature which lies for the expansion of plastic preforms to plastic containers.
- the container during filling under a temperature of 80 ° C, preferably maintained at a temperature of 60 ° C and more preferably below a temperature of 40 ° C.
- the container is deployed during the filling process.
- a wall section of the container advantageously moves relative to a further wall section of the container, in particular along a longitudinal direction of the container.
- the container is a foldable container and in particular a plastic container and more preferably a blow-molded plastic container.
- the material of the container may also be another, in particular foldable, material, such as a metal, in particular aluminum.
- the air oxygen is reduced by the small volume and can be additionally improved by a single or even multiple evacuation and gas purging.
- the evacuation in glass bottles known in the prior art can also be carried out here by a supporting action of a punch (described in more detail below). It would also be possible for a start of filling to take place in an evacuated container.
- Another advantage is that the volume expansion during filling no return gas flow is required. This in turn results in a simple valve assembly and possibly also a stroke-controlled flow rate control. It would also be possible to regulate the filling pressure via the lifting movement. For example, it would also be possible for the container to be expanded on the one hand by the filling pressure, but on the other hand, if necessary, to support the container during the filling process is increased by the device itself in terms of their volume and in this way the filling process is facilitated. A filling of the container overhead is also possible. This brings an advantage, for example, with regard to a special product protection.
- the container is expanded by a filling pressure applied during filling.
- the force required to mold the container in a controlled manner is high, but it does not have to be specially produced for this purpose.
- the power generation can predominantly and preferably also arise exclusively from the filling pressure itself.
- a distance between a bottom region and the mouth of the container changes during filling.

- said distance is circumferential in the circumferential direction. It is possible that during the filling of this distance is also increased by the pressures occurring.
- the mouth of the container is removed at least temporarily during the filling process at a predetermined speed from the bottom portion of the container and at the same time said folding edge moves away from the bottom portion at a speed that is halved relative to that speed.
- a filling element is locked relative to the mouth during filling. In this way it can be achieved that during filling by the filling pressure, the filling element does not slip off the mouth.
- the filling element is sealed against the mouth.
- At least a portion of the Be Daveniswandung is deformed during the filling process.
- This is advantageously a section of the container which lies below the mouth and particularly preferably in a region of a container shoulder.
- the folding edge disappears during the filling process.
- an annular section of the container is bent relative to a further annular section of the container by an angle which is greater than 20 °, preferably greater than 40 °, preferably greater than 60 °, preferably greater than 90 °, preferably greater than 120 ° and preferably greater than 150 °.
- the container forms in a folded state of a second folding edge, wherein advantageously this second fold edge is also formed circumferentially.
- a distance between the first folded edge and the second folded edge advantageously reduces.
- the second folding edge also forms a plane that is perpendicular to the longitudinal direction of the container.
- the container in a folded state, apart from these two folded edges, has no further folds.
- the present invention is further directed to an apparatus for filling expandable containers, said apparatus having a filling element, through which a liquid can be supplied to the container via its mouth. Furthermore, the device has a first holding device for holding a bottom region of the container and a second holding device for holding a mouth region of the container.

As shown in Fig. 7b, the container wall of the container 10 must be passed by itself. In order to achieve a wrinkle-free nesting of the container, it is necessary that the tool used for rolling in or folding be adapted as exactly as possible to the diameter of the container. Since, as shown in Fig.
- the wall of the container is passed to itself, the diameter of either the now inner wall 10f must be reduced and / or the diameter of the outer wall 10g to be increased.
- the Applicant has found that, in fact, the diameter of the inner wall 10f is typically compressed.
- FIGS. 8a and 8b show a further possible embodiment of a container.
- the container has a cylindrical container wall, which initially widens in the direction of a central region 10 h and then tapers again. Again, the refolding of the container is shown in Fig. 8b again. It can be seen that the upper portion of the container rests against the lower region in a folded or rolled-up state, since these expand or taper in the same way or at the same angle.
- FIG. 9 illustrates the deformation in an opening region 10a of the container 10.
- the right part of the figure in FIG. 9 shows the deformation in the shoulder region.
- the shoulder region it would be possible, in particular, for the shoulder region to be embodied in the shape of a sphere or in a spherical shape so as to facilitate the deformation, as shown in FIG. 9.
- Fig. 10 is an illustration for illustrating a forming or folding or curling operation. It is difficult in itself to make the two walls with a previous difference in diameter, since this point of the container wall has to be passed by itself. Nevertheless, a wrinkle-free upsetting of the wall of the container To reach nisses, it is proposed to create an internal pressure P1 for supporting the container wall to be compressed. This can be done, for example, that after the manufacture of the container, an outlet of air is permitted only in a defined manner.
- Fig. 1 1 a and 1 1 b show an advantageous embodiment of a container according to the invention. It can be seen that here three diameters A, B, C are provided in different sections of the container 10. The purpose of these different diameters is not curling, but later stackability. When looking closely, it is noticeable that the upper diameter A in the blown original form is larger than the lower diameter C, although these are rolled into each other in opposite directions, that is, the area with the present diameter A is rolled into the region C. The Applicant has found that by such a choice, that is, a larger diameter, or a larger cross-section of that portion of the container, which is rolled into another, a largely crease-free compression of the container can be achieved.
- Fig. 1 1 b shows a corresponding folded or rolled-up state of the container.
- An upsetting of the container diameter is limited by the material properties as well as by physical factors such as pressure, temperature and the wall thickness and the container diameter. If too much deformation occurs due to a compression process, the diameter can become so small that the wall buckles. If the diameter is too large or the forming too small, the rolling radius is too small to ensure proper or stress-free curling.
- Fig. 12a shows a situation where the diameter differences are too large. In this case, kinks occur in the wall or the wall section 10f. In the illustration shown in Fig. 10b, the curling due to the small radius of curvature in the region of the fold 10d can also be problematic.
- FIGS. 13a and 13b show a further embodiment of the container.
- the container has a roughly spherical shape shown in Fig. 13b in the mouth and bottom area.
- a spherical shape is favorable for PET containers in order to realize the largest volume with the possibility of thin wall thicknesses or high pressure stability.
- the diameter D of the container is limited (for example, by the force for emptying and the packing mass), or the spherical shape must or can be extended, as shown in Fig. 13b.
- Fig. 13b is located between two spherical bottom and mouth areas a cylindrical or rectilinear section.
- Fig. 14 shows a further embodiment of such a container. Since the height is limited, can be tried here, with as little material use a spherical shape at the ends, here, for example, down flatten. In this case, offers a stiffening through the mouth and the bottom of the container. Since a mouth 10a (which preferably has a screw cap or a snap closure) is kept small in contrast to the bottom area (for small closures and little use of material in the mouth area), but the floor area should be large (to ensure a secure footprint), Also, different flattenings, as shown in FIG. 14, may result.
- a mouth 10a which preferably has a screw cap or a snap closure
- Fig. 15 shows a container in a folded or rolled-up state. It can be seen that the shape of the bottom region 10b and the shoulder or the mouth region 10a are connected, so that they fit together as well as possible during curling.
- the floor area 10b must satisfy the requirements of high stability, but on the other hand it must also allow a good emptying with a small residual quantity. For this purpose, if necessary, a deformation of the feet during emptying be accepted.
- Fig. 17 shows another illustration of a bottom portion 10b.
- the container is designed so that it can be stuck in a container of identical design up to a minimum requirement resulting from the mouth and the bottom mold.
- the shoulder area is largely adapted to the floor area.
- the envelope diameter (this is the diameter from which the shoulder is deformed) is selected such that the mouth disappears far enough in the floor area or foot space.
- Fig. 18 shows a further illustration of a plurality of containers stacked one inside the other. It is possible that containers are stacked with or without closure. If the containers have a closure, a valve function is advantageously integrated in this closure in order not to have to dismantle the closure for filling. In addition, however, it is also conceivable that a simplified transport cap is provided as a transport protection and / or a protective cap.
- the container 10 has an improved or special barrier property with respect to C0 2 permeation from the inside to the outside and / or from oxygen permeation from outside to inside.
- the container may have additives, such as so-called scavengers.
- a material with scavenger properties is a material that can trap oxygen.
- the material itself may have this property or contain substances which absorb oxygen.
- substances with scavenger properties can be added to the material of the container.
- the scavenger intercepts, for example, in a seal the oxygen that is still in the headspace of the filled and sealed bottle. Particularly advantageous is the use of such a scavenger for oxygen-sensitive filling products.
- FIGS. 19a-g show several representations of containers with identification elements.
- the illustration shown in FIG. 19a illustrates in which areas such an identification element 80 can be arranged. This can be located, for example, on or in a closure 82 of the container, on a carrying handle 84 or on a wall region of the container 10 or a bottom region of the container 10. It would also be conceivable to have several such identification elements which are themselves in particular to RFID chips, provide.
- Fig. 19b shows an illustration in which the identification element 80 is arranged on a carrying handle.
- This handle 84 can be snapped over an opening of the container on this means of Aufschnappstoffs 94.
- the identification element 80 may be integrated or glued into the carrying handle 84, for example.
- the carrying handle 84 is advantageously arranged undetachably on the container, whereby thus also a fixation of the identification element 80 takes place on the container.
- the carrying handle is removable or difficult to remove.
- FIG. 19 c shows a representation in which the identification element is arranged on a closure 82 of the container 10. Again, the identification element can be integrated into this closure but also about glued.
- 19d shows a representation in which the identification element 80 is arranged on a bottom or on a circumferential wall of the container. Again, the identification element can be introduced or integrated. In particular, in the case of an arrangement on the wall, the identification element can also be integrated into a label attached to the container.
- the identification element is arranged at a position of the container, which does not lie in a region of the circumferential folding edge during the removal process.
- RFID chips In addition to the use of RFID chips, other identification elements such as, in particular, bar codes or QR codes could also be used. These could, for example, also be printed on a wall of the container.
- FIG. 19e shows a further possible arrangement for an identification element 80.
- the identification element is arranged on a support ring, which is located in an opening region of the container 10.
- Fig. 9f shows a more detailed representation.
- the identification element also has an antenna 81 which extends around the mouth 10b of the container 10 here.
- 19g shows a representation to illustrate the readout of an identification element 80.
- This identification element 80 is here at a peripheral wall of the arranged.
- This device for removing liquid here has an annular read-out device 90 for reading out the identification element.
- This has the advantage that the container for the purpose of reading does not have to be arranged in the removal device in accordance with the rotational position. Conversely, however, it may just as well be that the identification element can only be read in a precisely defined rotational position. In this case, the identification element can also be used to ensure a rotational position-appropriate arrangement of the container in the removal device.
