Definitions

  • the invention relates to a container, especially a container suited for storing granular material, in which container there is a shell section, polygonal in cross section, and advantageously surrounding a bag made of plastic.
  • the shell part is composed of liners and fluting cardboard placed between them.
  • the container includes a separate base section and a lid section.
  • the container shell In order for the above objects to be attained, it is necessary for the container shell to be provided with a structure allowing the shell to be extended in height during the filling operation so that the shell can be filled to the brim. Similarly, it should be possible to reduce the height of the shell to allow for compaction of the plastic raw material once the lid has been placed in position.
  • a container in accordance with the invention is easy to manufacture and use. It is provided with a flexible brimming edge made of a single liner and positioned at the top of the shell section.
  • the said brimming edge makes it possible for the plastic bag placed inside the container for receiving the plastic raw material to be filled to the brim in excess of the actual height of the shell section. This in turn is essential in preventing the level of the granular plastic raw material in the container to fall below the level of the top edge of the container shell as this would cause the weight of an overlying container to focus on the edges of the shell of the underlying container.
  • a container of this type is, of course, suited for the storage of all kinds of granular material.
  • the liner forming the outer surface of the shell section of the container in accordance with the invention is preferably reinforced by webbing in order that even a fairly thin liner would be able to withstand the international drop test referred to in the above.
  • the said web reinforcement can, of course, be incorporated in any liner, and in several liners in fact, should the need arise.
  • the shell of a container in accordance with the invention is manufactured preferably from an attachment surplus and a section essentially rectangular in shape divided into partial sections of equal size by means of parallel creasings.
  • the blank i.e. the base material for the container
  • the blank's outer liner, forming the inner liner of the shell of a finished container, is wider than the other layers in the blank. This being so, that part of the wider liner that extends above the other layers of the blank forms the container's flexible brimming edge.
  • Fluting cardboard and cardboard are particularly suitable as blank material. Other corresponding materials may also be appropriate. When necessary, the number of liner and fluting cardboard layers implemented may exceed those mentioned in the above.
  • the prior art container shown in fig. 1 consists of two external sleeve structures (2, 3) of the octagonal shell (1).
  • the upper sleeve structure (2) is shown in the position that it assumes when supported by the protrusions (4, 5) in the shell (1).
  • Figure 1 also shows the container's octagonal base section (6) that fits inside the container's shell (1).
  • the container's octagonal lid section (7) fits around the outside of the upper sleeve structure (2). When the lid (7) is placed in position and pressed down, it in turn forces the upper sleeve structure (2) down because the protrusions (4, 5) have been so formed as to give way.
  • the plastic bag inside the container is indicated by the numeral 9.
  • the prior art container shown in figure 2 corresponds to the container shown in figure 1 except for the one only sleeve structure (2), essentially equal in height to the shell (1), used in connection with the container shown in figure 2.
  • the container in accordance with the invention there is a flexible brimming edge (8) formed on the upper edge of the container shell (1), the said brimming edge superseding the sleeve structures.
  • the outermost liner in the finished container according to the invention is net-reinforced in order to have the container pass the international drop test.
  • the container's octagonal base (6) fits inside the container's shell (1) and the octagonal lid (7) is guided into the container's shell section (1).
  • the brimming edge (8) is formed of a simple liner, its rigidity is sufficient to support it during the filling up of the plastic bag (9) inserted into the container.
  • the lid (7) is placed in position over the container, the brimming edge (8) crumples easily under the lid when a load is imposed upon the lid (7).
  • the container in accordance with the invention is formed preferably of the blank shown in figure 4, the said blank being essentially rectangular in shape and in it the liner acting as the outside liner at this stage is wider than the other cardboard layers.
  • this wider outside liner becomes the shell's inside liner and provides the container with the flexible brimming edge (8).
  • Parallel creasing is employed in dividing the blank suitably into the attachment section (11) and eight sections (10) of equal width.
  • the said attachment section is used to connect the blank's ends to one another. The most appropriate means of attaching the ends is by using glue and staples. It is thus possible to keep the container shell folded flat during transportation and storage so as to use less room. When this is done, the shell is folded out into its octagonal shape just prior to the filling stage at which stage its base section (6) and the plastic bag (9) are put in their positions.
  • the invention also includes a container circular in cross section. During transportation this type of container can be kept stacked with the end seam glued and pressed flat along two opposite folding creases. Alternatively, the gluing of the container seam can be carried out at the filling stage at which stage the blanks can be transported fully open in stacks, thereby avoiding the structural weakenings to the shell caused by the creasings.
