Definitions

  • the present invention relates to a flexible container for a fluid material.
  • fluid material any material having the property of flowing freely, or of marrying the shape of its container.
  • fluid material any material having the property of flowing freely, or of marrying the shape of its container.
  • this definition is meant in particular any liquid, viscous material, but also any solid material in particulate or discrete form, such as powder, granules, etc.
  • a flexible container for fluid material having a generally tubular shape in a longitudinal direction or height, for example vertical, and delimiting in cross section , perpendicular to the longitudinal direction, for example in median horizontal section according to the height, different sound storage areas for the fluid material, including at least one main area, for example a central area of octagonal shape, and at least four peripheral areas, for example in the shape of an equilateral triangle, distributed regularly outside the main area, for example at the four corners of the central octagonal area.
  • each peripheral zone communicates with the latter, with regard to or vis-à-vis the stored material, according to a plurality of communication orifices, distributed according to the longitudinal extension of the container, and ensuring the filling of the peripheral zones from the central zone.
  • a container can comprise, at one of its ends in the longitudinal direction, for example at its upper end, a filling means, such as a chute, and at its other end, for example at its lower end, an emptying means, such as a chute.
  • Such containers are generally produced in the following manner.
  • the inner envelope comprises a plurality of panels, for example eight panels of equal width, arranged in the longitudinal direction, some perforated, others solid or sealed with respect to the material to be stored, the perforated panels alternating with the panels unperforated or solid.
  • the two edges of the inner envelope are joined or assembled to each other in the longitudinal direction, to delimit the main or central storage area.
  • the four outer sides are partly assembled in contact with the inner envelope, by junction or connection of each non-perforated panel with an outer side, along the two longitudinal edges of said panel.
  • the free longitudinal edges of the outer sides are then assembled in pairs to delimit the peripheral storage areas, outside the main or central storage area, which communicates with the peripheral storage areas by the perforated panels of the envelope. interior.
  • the filling means and the emptying means are reported respectively, and this by assembling suitable parts, for example a straight wall with central chute, along the edges transverse of the upper contour and the lower contour of the body of the container obtained as above.
  • gripping fasteners consisting of lifting straps, suitable for gripping by the fork, are fixed to the upper end of the container.
  • a cart or other mechanical lifting means are fixed to the upper end of the container.
  • flexible wall means any material or material in sheet form, or of thin thickness compared to its other dimensions, having no inherent rigidity, such as paper, films or sheets of plastic material, fabrics , fabrics or textile materials, in particular fibers or threads of a plastic material such as polypropylene, plastic laminates, etc.
  • connection joint of assembly any means making it possible to carry out an assembly line between two edges or adjacent edges of at least two distinct elements of flexible wall, such as sides or panels .
  • This definition means as different as an assembly by sewing, welding, gluing, etc.
  • the flexible containers as described above have a relative fragility in the peripheral storage areas and the corresponding external walls, vis-à-vis, on the one hand, the pressure exerted by the weight of the fluid material stored at this location, and on the other hand shocks or other aggressions following handling or transporting full or loaded containers.
  • the containers described above have a complexity, or even difficulties in production or mass production.
  • the assembly joints are made by sewing, according to the preceding description, it is necessary to make at least eight seams of the inner envelope, flat and with a particular sewing machine, taking into account the assembly selected, and at least four seams on the outside.
  • these seams become a substantial obstacle to productivity.
  • the greater the number of seams the more the overall fragility or the tightness of the flexible container can be compromised.
  • the present invention relates to a flexible container as defined above, having good resistance in its peripheral storage areas, and much simpler industrial production.
  • the container body comprises at least four tubular elements in a flexible and continuous wall, each delimiting a peripheral storage area, and at least four widths in a flexible wall, closing the tubular elements together, and delimiting with these the main storage area.
  • the outer wall of the peripheral zones is obtained without a longitudinal joining joint, for example seamless, and can conform to a cylindrical contour, which, all other things being equal, gives the container very good resistance. to impact, but also to bursting under the effect of the weight of the strocked material.
  • the container is provided with grips, each consisting of a link shaped according to a handle, arranged at the upper end of a corresponding tubular element, with two branches arranged longitudinally , and assembled to the two connecting joints of said tubular element, respectively.
  • all the flexible wall elements identified above are assembled or linked to each other by suitable seals, for example seams, arranged according to the height as regards the body (1), and along the outer periphery of the latter, as regards the filling means (6) and the emptying means (9), arranged essentially transversely, that is to say perpendicular to the longitudinal direction or height of the container.
  • suitable seals for example seams
  • the tubular element (2a) it is assembled on either side to the two widths (3a) and (3d) respectively, according to two longitudinal joints (12a) connecting, corresponding to two generatrices of the tubular element (2a), which are arranged in a plane passing through the axis of the tubular element (2a), in the full conformation of the latter.
  • Gripping fasteners (14a) to (14d) are associated with the upper end of the peripheral storage areas (2a) to (2d).
  • each attachment consists of a link shaped according to a handle, (15a) for example, arranged at the upper end of a corresponding tubular element, (2a) for example, with two branches arranged longitudinally , for example (16a), and assembled to the two connecting joints (12a) of the same tubular element (2a), respectively.
  • each link or fastener (14) consists of a strip shaped transversely in a bar, according to the extension of the two branches (16) of assembly with a corresponding tubular element (2). And the two opposite edges (141) and (142) of this bar enclose, by means of an appropriate seam, the connection joint (12) of the tubular element (2) with an adjacent width (3).
  • Such an arrangement makes it possible to ensure the sealing of the assembly joints (12) if necessary, by using the strip or the link corresponding to each fastener (14) of gripping.
