    Packaging container and method for filling the container with bitumen
    The invention relates to large-volume packaging containers for thermoplastic materials, in particular bitumen, the container having a base panel and a container jacket connected thereto wall plates of flexible material, in particular flat or woven fabric made of synthetic fibers such as polypropylene (PP) or polyethylene (PE) or biodegradable Natural fibers and optionally provided with an inner coating of PP or PE, has.
    Large-volume packaging containers of the above type are for a long time for the transport of large quantities of pourable or flowable goods in use and are also known under the keyword "big bag". The containers must be cost-effective to manufacture, the applications according to load-bearing and wear-resistant and useful in handling during filling, during transport and during emptying. The production must also be economical in large quantities, with the least possible sewing work required and the manufacture also with simple means, e.g. should be possible in developing countries. Nevertheless, the dimensional precision must be ensured even in the series. Moreover, it is desired to be able to choose from a wider variety of fabrics such as e.g. made of plastic, but also of biodegradable natural materials such as jute, flax, etc.
    It has already been known, e.g. by AT 505 805 B1, to use such packaging containers for packaging a thermoplastic material, namely bitumen. Thermoplastic materials and especially bitumen are difficult to treat as contents, since it is a solidifying and solidified liquid, which shows a certain creep behavior even in the solid state.
    This leads disadvantageously to a lateral bulging of the shell of the transport container, whereby the outer shape dimensionally changed in such a way that the handling is difficult. This is especially true when a plurality of filled transport containers are to be stored in cargo areas or in containers, where only limited space is available. The dimensional changes of the filled sacks may cause the filled containers to fail to fill the filled containers without... 9 9 9 9 9 9 9 9 9 9 9 9 99 99 99... 999
    Damage can be loaded, wedged against each other during transport and the removal is very difficult.
    The storage and transport problem of bitumen has been earlier and is still currently solved by the use of rigid containers, e.g. the bitumen drums made of sheet steel. However, these are very expensive, have low filling volume and are environmentally problematic, as obtained after use with bitumen contaminated scrap.
    With regard to the use of flexible material packaging containers, it has previously been known in practice to sew stiffening or reinforcing elements into the containers, e.g. horizontal bands in the lower third of the container height or according to AT 505 805 B1 stabilizing means in the form of sewn folds which are sewn into the fabric panels forming the side walls. However, the attachment of additional sutures in tissues always presents problems such as e.g. the weakening of the sewn material and in addition all these measures are associated with additional material and sewing effort.
    Object of the present invention is to minimize the lateral bulging of the container in the lower part of the height of the container while maintaining the above requirements. Furthermore, the stability of the filled container should be ensured and further the fillable container volume should be optimized for given loading dimensions and conditions.
    According to the generic type large-volume packaging container is characterized in that the container casing is waisted in the bottom near bottom half of the height of the container.
    Preferably, the maximum waisting in the zone of the maximum hoop stress of the shell after filling the container with the thermoplastic material is arranged. The zone of maximum hoop stress and waist is conveniently in the range of 5% of the height of the container below to 10% of the height of the container above the perimeter of the maximum hoop stress. The side edges can advantageously proceed from the bottom-side corners in a first
    Section formed vertically or slightly inwardly inclined upward and be performed in a second portion arcuate to a curve turn line, said line is in the region of the transition of the horizontal circumferential line from approximately rectangular to approximately circular. More preferably, the container may be characterized in that the curvature turn line measured from the bottom is between 10% and 20% of the height of the container. The container may advantageously have above the zone of the maximum hoop stress a circumferential line of the minimum sidecut, which is in the range of half the height of the empty container, preferably between 45% and 70% of the overall height. In an alternative, the container may be characterized in that the container jacket is formed from sewn fabric panels forming the sidewall panels, the waist of the jacket being defined by respective sewing lines, and the bottom panel being sewn to the sidewall panels to form a bottom edge. According to another alternative, the container casing is made of a fabric tube, which is folded and sewn to the side edges to be formed, wherein preferably the protruding seams are cut off. Preferably, in the container, a thermoplastic material receiving inner bag made of plastic film is provided with a melting point above the filling temperature of the thermoplastic material. In each case two of the side edges can be connected to a lifting loop and the side edges can be reinforced with Kantgurten.
    Furthermore, the invention relates to a method for filling the packaging container according to the invention, which is characterized in that the container suspended from its lifting loops without contact with the ground, filled through the filler neck with heated bitumen and then parked with his bottom panel at the bottom and allowed to cool the bitumen.
    The invention will be described in more detail with reference to the drawings, for example. The embodiments relate, for example, to a transport container made of plastic fabric, in particular polyethylene (PE) or polypropylene (PP), the grammage usually being between 80 g / m.sup.2 to 300 g / m.sup.2 and preferably 160 g / m.sup.2. The grammage is, of course, the respective proportions in terms of load weight, container size and • ·· * ♦ · * · · · · · · · · · · · · · · ····································································: mechanical wear conditions. Different grammages for different parts of the transport container can also be used.
    Bitumen e.g. for road construction is filled in the hot state in filling stations, for example, at about 95 ° -120 ° C in the transport container. Therefore, any fabric used for the container must have the necessary thermal strength. Known such fabrics have e.g. at about 100 ° C, a stretch between about 10-20% in warp and weft on. If advantageously the bitumen is not introduced directly into the transport container, but into a plastic film inner container inserted in this container, then this typically has a softening point of about 100 ° -125 ° C., so that the bitumen is filled without it comes to a melting of the inner container. The melting point is typically only at 124 ° to about 138 ° C. When removing the bitumen by melting, it is possible to mitzuschmelzen this thin inner container with appropriate temperature and mitzuverarbeiten.
    Fig. 1 shows the tissue blank for a transport container according to the invention with marked location of various determining features.
    FIG. 2 shows the side view of a bag filled with the thermoplastic material and FIG. 3 shows a section along the line III-III in FIG. 2.
    It is the special feature of the present invention that the advantageous effect is caused only by the particular arrangement of the Nählinien forming the edges of the container, as will be explained in detail later.
    In Fig. 2 a finished filled bag is shown in side view. It comprises, in a known manner, a floor panel 1 made of fabric and, projecting upwards, the container casing 2, which is formed from four wall panels 3. At the top, the container can be closed by a container lid 4 with a filling opening 5. Of the loose in the container or suspended with fixations inner bag 6 only the upwardly protruding and closable filler neck can be seen. I ·· I · Φ · * ♦ «· • ·% ··· • ♦ ♦ • · 5 * ..
    The individual wall panels are sewn together to form the container shell at the side edges 7 and in a similar manner, the bottom panel 1 is sewn to the wall panels 3 to form the bottom edge 8. At the four corners 9, the bottom edges and the side edges abut each other.
    For holding and transporting the packaging container, hoisting loops 10 extending upward from the side edges 7 are provided, wherein each of the two lifting loops extends between two adjacent side edges 7. The lifting loops are preferably formed by continuously arranged Kantgurte 11, so that the load absorption when lifting distributed to the entire tissue to the floor panel.
    As can also be seen in FIG. 2, the container casing is fitted in that zone in which the bitumen exerts the greatest tension in the container casing. This waisting surprisingly compensates for the expansion of the fabric under the action of heat and internal pressure such that the container substantially maintains its upright shape. As can be seen in Fig. 2, the center 12 of each wall panel 3 is at maximum extent approximately perpendicular to the associated bottom edge. 8
    Furthermore, it can still be seen in FIG. 2 that below the sidecut the corners 9 of the container protrude bulging and how feet stabilize the sack.
    This is particularly apparent from Fig. 3, which shows a section through the filled transport container along the line Ill-III. Shaded inside is the thermoplastic material such as bitumen denoted by the reference numeral 13. The material receiving inner bag 6 is pressed against the container shell 2. The rectangular in the filled state container is filled in the horizontal sectional plane by the internal pressure substantially round, but the mantle to the rectangular bottom panel 1 passes into the rectangular shape, whereby four foot-like support structure 14 are formed. 6 6 «· · * • · +« * * · • 9 • ···
    ft »· ·» · · · · ft · ft «
    This all ensures that the container after emplacement with the thermoplastic material does not begin to emigrate laterally, loses its shape and ultimately becomes unusable with its contents.
    It is understood that the illustration in Fig. 3 is a representation of the ideal state, but in practice is so far reach that the desired benefits are guaranteed in a surprising manner.
    Returning to Fig. 1, the sewing line will be discussed below, by the particular arrangement of the desired advantages are achieved.
    The following measures or percentages refer to the height 15 of the container, which extends from the bottom edge 8 to the lid edge 16. The respective left and right marked boundary lines 21 represent, for example, the boundary edges of a fabric blank, as it can be present before sewing.
    The sewing line forms the course of the side edge 7 and runs as described below.
    Starting from the bottom-side corners 9, the side edges 7 extend in a first section D vertically or only slightly inwardly inclined until the sewing line in the second section A is guided arcuately to a curve turn line 17. This curve-turning line 17, which is only shown as a dot on the sewing line shown in FIG. 1, extends horizontally around the entire jacket and this line shows the transition of the horizontal circumferential line of the jacket in the filled state from approximately rectangular to approximately round. Preferably, this curvature turn line is measured from the bottom between 10% and 20% of the height 15 of the container.
    In the third section B is the maximum waist of the shell, this zone is that of the maximum hoop stress of the shell after filling of the container with the thermoplastic material. This is the zone in which, depending on the bag material and filling weight, the container is affected by the internal pressure of the container. · · · Material undergoes the greatest strains. The waisting is designed so that at maximum elongation, the filling contour 18 is not or only slightly exceeded, whereby the thermal expansion or shrinkage of container material and contents can be considered.
    The zone of the maximum hoop stress and thus the zone of the waist is preferably in the range 5% of the height of the container below and 10% of the height of the container above the circumferential line 19 of the maximum hoop stress.
    Above the third section B is the fourth section C, which has around the circumferential line 20, the minimum sidecut and thus again allows more filling volume in the container. This circumferential line 20 of the zone C is approximately in the range of half the height of the empty container, preferably between 45% and 70% of the overall height 15.
    Large-volume packaging containers having the features described here not only have the advantage of dimensional stability, stability and cost-effective production, but also allow in surprisingly larger filling volumes than the known packaging containers of this type, since it is possible by the high dimensional stability, the base of the packaging container To enlarge the dimensions of the floor panel 1 slightly, without causing problems when transporting in containers, trucks or the like. For example, if previous standard fill volumes range from 900 to 1,000 kg, this volume can be increased by almost 200 kg, which offers a significant cost advantage.
    The present invention also relates to an advantageous method for filling the described packaging containers with thermoplastic material and in particular with bitumen. It was known to carry out the filling of the packaging container while standing. However, it has surprisingly been found that it leads to an increase in the filling volume as well as a greater stability of the transport container after cooling, when the packaging containers are suspended during filling at their lifting loops without contact with the ground. Due to the bending of the fencing board, which is made possible thereby, an additional filling volume results, which, when the container is turned off while still warm and after cooling to ambient temperature, reduces the volume loss resulting from the loss of volume by * * * * * * 51047 Pe / Fl * · * · · · ♦ * · * · Λ t · · · · · · t I · 1 t ·· · »
    Shrinkage compensates. As a result, the filling volume is increased overall and the increased internal pressure has a favorable effect on the dimensional stability.
    If position-dependent information such as top, bottom, horizontal or vertical has been used in the description, this information refers to the normal position of use in which the bottom panel is in a horizontal position.
    Furthermore, it may be advantageous to reinforce the transport container in the lower region of the container shell with additional layers of fabric.
