Flexible liner for shipping bulk load inside shipping containers and method for placing said flexible liner for shipping bulk load into a shipping container

摘要

The present invention refers to a flexible liner for shipping bulk load inside shipping containers which is basically constituted of a flexible sack or bag made of impermeable plastic material, preferably of impermeable propylene, which is sized to be placed in standard containers, that will be able to provide the safe transport of bulk loads, and which uses fastening means that will keep suspended the flexible liner from the superior part of the container, and said container having an optional wall as roof, a floor wall, left and right side walls, a closed front wall and a back wall that may comprise an or more doors, while the flexible liner to be placed inside said container also comprises part of the optional roof wall, part of floor wall, parts of left and right side walls, part of closed front wall and part of back wall, by which the loading of said flexible liner may be performed, and said flexible liner of this invention is characterized by the fact of using means of retention of said part of the back wall of the flexible liner, using frontal transversal retention strips, which are diagonally disposed forming a X on the external surface of said part of back wall of the flexible liner, and said frontal transversal retention strips of part of the back wall of the flexible liner will be pressured, by means of a tensioning device, in order to be kept stable in a tensioned way, what will be reached by using double buckles, being further provided another vertical fastening strip, which extends centrally from the inferior border of part of the back wall of the flexible liner, and which extends up to a middle height of said part of the back wall of the flexible liner, and said vertical fastening strip will be responsible for keeping the intercession point positioned among these said frontal transversal strips of retention of part of back wall of the flexible liner, and both said frontal transversal strips of retention, and said vertical fastening strip, disposed in the part of the back wall of the flexible liner are made of materials with a high traction resistance, in order to guarantee a perfect stabilization of said part of the back wall of said flexible liner, reducing substantially the tendency of arching of said part of the back wall of said flexible liner, which occurs in function of the internal pressure that is submitted by the loading of the flexible liner, and, due to the fact that the fastening of said part of the back wall of the flexible liner be performed using a tensioning device, it will be possible to guarantee a great reliability on the retention of said part of the back wall of the flexible liner, with minimum effort from the operator.
