Definitions
- Container for storing or transporting bitumen.
- the invention relates to a container, preferably a
- large-volume container particularly preferably for storage or transport of a liquid or viscous or creepable filling, in particular bitumen.
- Such a container is the applicant as a bitumen container z. B. from published WO2009 / 043071 (application number PCT / AT2008 / 000350) and has a recorded within its container wall
- Inner bag into which viscous bitumen is filled as filling material.
- Bitumen is a liquid which is liquid to viscous at high temperatures and solidified at low temperatures.
- Solidified melts have the property that they also lower
- the container wall of the bitumen container is made of a number of fabric panels, with side panels sewn together at their side edges to form the sidewall of the bitumen container.
- a likewise executed as a separate fabric panel flat bottom wall is circumferentially at its outer edges with the corresponding lower edges of the
- the flat bottom thus formed has a high
- bitumen-filled bitumen container is also easy to stack. In the case of the known container, however, there is the risk that when filling with bitumen between the inner bag and the container wall can form bubbles inclusion. To the bubbles inclusion comes through bitumen, which initially builds approximately centrally in the course of filling the bitumen tank on the flat ground and moves from there relatively unpredictable to the side panels out or distributed. This can lead to material distributions that prevent the escape of air from a gap between the inner bag and the container wall.
- the formation of air bubbles preferably occurs in regions of the connection between the side wall and the bottom wall, that is to say at the lower end of the side wall of the bitumen container.
- bitumen container due to the relatively high total mass of the overlying bitumen (500 to 1000 kg) to be expected with an extreme load on the container structure, in particular the inner bag.
- the air bubbles formed during filling are initially unproblematic and inconspicuous. Over time, such as during subsequent transport or even during prolonged storage, e.g. Bitumen containers are stacked on top of each other and the load increases, it can in
- the object of the invention has been found a container
- the object of the invention is therefore a container, preferably large-volume container, particularly preferably for storage or transport of a liquid or viscous or creepable filling material, in particular bitumen, comprising a container wall which is formed by flexible material webs, each with its longitudinal edges Help of longitudinal seams are interconnected, wherein for forming a bottom area
- adjacent webs of material are interconnected by at least one additional seam spaced at a distance from the lower end of the
- Material web begins in the region of said longitudinal seams and extends in a direction deviating from the orientation of the longitudinal seam orientation toward the lower end of the material web.
- the upper end of the at least one additional seam is correspondingly far away from the upper edge of the container in order to obtain a sufficient container volume.
- each web extends continuously from the upper edge (head) to the lower edge (foot) of the container. According to this extension, each web integrally forms both a sidewall portion and a bottom wall portion of the container. Along the respective material web, during filling or when the container is filled, a continuously extending, (slightly) curved transition region is formed between the side wall and bottom wall region formed by it.
- an obtuse angle measured between the longitudinal seam viewed in the direction towards the head of the container and extending from the longitudinal seam extending additional seam present or a curve with continuous
- the thus formed structure of the floor area and in particular the transition area between the bottom wall and the side wall has the consequence that when filling the bag it is ensured that the contents reliably distributed to the lowest point of the container and begins to build up the contents there continuously.
- An inserted into the container inner bag, in which the filling material is filled and with which the contents are in direct contact, is thus continuously filled from bottom to top with the contents and nestles in succession with increasing level starting at the lowest point of the container continuously to the inside of the
