Definitions

  • the invention relates to a container, especially a con ⁇ tainer 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 con ⁇ tainer includes a separate base section and a lid sec- tion.
  • Containers used for transportation and storage purposes are placed one on top of the other and consequently the lowermost containers carry the weight of those above them.
  • the weight ought to focus via the container lid onto the granules of the plastic raw material and from them onto as large an area as possible of the internal surface of the container' shell.
  • the container shell In order for the above objects to be attained, it is ne- cessary 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 flex- ible 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 pre ⁇ ferably 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 rein- forcement 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 con ⁇ tainer
  • 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 corre ⁇ sponding materials may also be appropriate. When necessa- ry, the number of liner and fluting cardboard layers im ⁇ plemented may exceed those mentioned in the above.
  • Fig. 1 depicts a prior art container provided with two sleeve structures
  • Fig. 2 depicts a prior art container provided with one sleeve structure
  • Fig. 3 depicts a container in accordance with the in- vention
  • Fig. 4 depicts a blank used in the construction of a container in accordance with the invention.
  • 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 posi ⁇ tion that it assumes when supported .by the protrusions (4, 5) in the shell (1).
  • Figure l also shows the con- tainer's octagonal base section (6) that fits inside the container's shell (1) .
  • the container's octagonal lid sec ⁇ tion (7) fits around the outside of the upper sleeve structure (2) .
  • 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 con ⁇ tainer 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 fill- ing up of the plastic bag (9) inserted into the con ⁇ tainer.
  • 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 sec ⁇ tion (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 oc ⁇ tagonal 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.
  • this type of container can be kept stacked with the end seam glued and pressed flat along two opposite folding creases.
  • the gluing of the container seam can be carried out at the filling stage at which stage the blanks can be trans ⁇ ported fully open in stacks, thereby avoiding the struc- tural weakenings to the shell caused by the creasings.

Abstract

Conteneur convenant particulièrement au stockage de matériau plastique granulé brut. Le conteneur possède une enveloppe de section octogonale ou cylindrique (1) enveloppant avantageusement un sac plastique (9). L'enveloppe (1) est constituée de doublures et de couches de carton ondulé placées entre celles-ci. Le bord supérieur de l'enveloppe (1) est équipé d'une doublure constituant un rebord souple (8), celui-ci rendant possible le remplissage du conteneur jusqu'au bord. Par contre, lorsqu'on ferme le conteneur et qu'on exerce une pression sur le couvercle (7) après avoir compacté le matériau granulé dans le sac plastique (9), le rebord (8) se plie.
