Definitions

  • the present invention concerns packagings and containers obtained from die cut and folded sheets and in particular it concerns a new container obtained from one or more die cut and folded sheets, provided with inner modular compartments.
  • Containers are known for packaging solid or liquid materials and substances of various kind, which can be food products or not.
  • containers are known that are obtained from one or more sheets of cardboard, plastic, plasticized paper or other suitable materials, shaped by die cutting and suited to be folded along folding lines to form a container provided with bottom, sides and cover, usually attached to the sheet itself.
  • the die cut sheets for making containers are usually manufactured through extremely simple production processes: the containers are obtained from a continuous mass production process, wherein each sheet or part of a sheet is shaped by means of a press or hollow punch provided with shaped cutting edges that cut the sheet according to a predefined shape. The sheet is then subjected to a creasing or grooving operation in order to produce, on the surface of the die cut sheet, grooves that define the folding lines of the sheet.
  • the flat die cut sheets thus obtained have limited overall dimensions and therefore can be stacked on top of one another, thus obtaining reduced stocking volumes that facilitate handling and transport.
  • the die cut sheet is folded along the folding lines by means of suitable mechanical devices, thus obtaining the container.
  • the edges of the sheet are usually provided with assembly tabs suited to be folded and glued onto the edges of the adjacent folded parts, in order to prevent the unfolding of the sheet and maintain the shape of the container.
  • the product to be packaged is introduced in the container after or during the folding operation. Finally, the container is closed by folding the cover, joined to one of the sides, and fastening it to the opposite side and/or to the adjacent sides.
  • Cardboard containers are known that are used for packaging dry food such as dry pasta. Pasta is packaged at the end of its production process, which substantially includes the steps of kneading, extrusion through dies and final drying, during which the product loses most of the water it contains and assumes the known appearance and consistency.
  • the dry pasta processed as described above is thus put on conveyor belts or devices and conveyed into dispensing units that divide it into predetermined quantities to be packaged individually.
  • Each one of said quantities is automatically or semiautomatically introduced into the container, according to the type of product to be packaged.
  • packets containing 250 g, 500 g or 1000 g of pasta are known and particularly widespread for domestic use.
  • Said containers made from cardboard cannot be sealed repeatedly but once they have been opened they can be closed, for example, by fitting a peripheral part or a tab of the cover into a special slot created in the opposite side of the container. Since in this way the container is closed but not sealed, insects or dirt may get into it and furthermore the pasta is exposed to air and thus deteriorates more quickly, with consequent bad smells and tastes.
  • the subject of the present invention is a new type of container obtained from one or more die cut and folded sheets, with one or more modular inner compartments, each one with a cover or covering element that can be opened individually.
  • the main object of the present invention is to guarantee the correct preservation of products, in particular food products like dry pasta or other products, by dividing the contents of the container into predefined portions, and wherein each portion is contained in a modular compartment, provided with its own cover that can be opened individually.
  • Another important object of the present invention is to guarantee the correct preservation of the product that has not been used, even after the packet has been firstly opened, since the residual product is contained in compartments that are still closed and is thus protected against humidity and dirt.
  • Another important advantage offered by the present invention lies in that it can be mass produced, using simple and economic materials and equipment.
  • a further important advantage offered by the invention is its compact shape, thanks to which it is not bulky and can be easily stocked, both in its three- dimensional folded form and in its flat unfolded form.
  • a further important advantage offered by the present invention is represented by the fact that it protects the product contained therein from bad smells, dirt, humidity, being preferably made of a plastic or plasticized material suitable for use with food products.
  • the new container obtained from one or more die cut and folded sheets, with one or more modular inner compartments, each one provided with a cover that can be opened individually.
  • the new container is obtained from one or more sheets, made of cardboard, plastic or multilayer material, particularly suitable for containing the specific type of material or substance, be it liquid or solid, for which it has been designed, wherein said sheets are die cut and creased and successively folded to form a container provided with bottom, sides and one or more substantially vertical inner partitions defining two or more modular inner compartments, and wherein each one of said compartments is provided with a cover.
  • all the said parts, bottom, sides, partitions and cover/covers belong to a single, die cut and folded sheet.
  • said die cut sheet comprises a substantially rectangular part that constitutes the development of the sides and inner partitions of the container.
  • the height of said rectangular part substantially determines the height of the container, while its length determines the development of the sides and partitions of the container, excluding any assembly tabs.
  • Said rectangular part is provided with a plurality of parallel folding lines developing in the direction of the height, wherein the portion of the sheet included between two successive folding lines defines a side or a partition of the container. Said folding lines can be equally spaced or positioned at different distances, according to the geometric shape of the container to be obtained.
  • a three-dimensional volume for example substantially cylindrical or preferably prismatic, with polygonal cross section, for example hexagonal, or triangular, square, octogonal, etc., as well as the inner compartments, defined and delimited by said partitions and/or by said sides themselves.
  • Said sheet also comprises at least one flat folding part whose shape substantially corresponds to the cross section of said prism or cylinder and serving as the bottom of the container.
  • Said flat part is joined to said rectangular part on one of the longitudinal sides, crosswise to said folding lines, here below referred to as the lower side, while on the opposite or upper side, in a suitable position, there are one or more further parts that make up the cover/covers of the container.
  • the sheet may comprise a single folding part serving as a cover, whose shape and size substantially correspond to the cross section of the prism or cylinder, and on which there are pre-cut or pre-drilled lines that define detachable parts, each in a position corresponding to each one of said compartments defined by the partitions present inside the container.
  • each one of said detachable parts may have a shape corresponding to and dimensions comparable to or slightly smaller than the cross section of the compartment defined by the sides and the partitions.
  • the sheet may comprise, attached to the upper edge of said rectangular part, at the level of the top of the sides, one or more folding parts, each one serving as the cover of the corresponding compartment.
  • each one of said cover of the compartments may have shape and size corresponding to the cross section of the relative compartment.
  • Each one of said folding parts serving as cover and bottom is also provided with assembly perimetral folding tabs for fastening it to the sides of the container.
  • the new container may be in the shape of a prism with hexagonal, square, triangular, octagonal cross section or the like, depending on the shape of the die cut sheet.
  • the new container may be in the shape of a right-angled prism with hexagonal cross section, divided by means of said partitions arranged radially into six inner compartments, all preferably having the shape of a prism with equilateral triangular cross section.
  • Said container is obtained by folding at least one die cut sheet comprising said rectangular part divided, by folding lines, into six successive portions defining the sides of the container and into one or more successive portions making up the partitions that divide the inner volume of the container into two or more prism-shaped compartments, for example with triangular cross section.
  • the hexagonal bottom is attached to the lower edge of said rectangular part at the level of the base of one side, while the cover/covers of the compartment/compartments is/are attached to the upper edge of the rectangular part at the level of one or more of said sides.
  • the new container may be in the shape of a right-angled parallelepiped, that is, with square or rectangular cross section, divided into modular inner compartments with triangular or square cross section.
  • the container obtained by die cutting and folding a single sheet shaped as described above, thus comprises a plurality of modular compartments, each one covered with a removable part or cover. Each compartment is suited to contain part of the total contents of the container.
  • the consumer who intends to use one or more portions of the product opens, for example by tearing, only one or more of said compartments, removing the corresponding covers, so that the other compartments remain closed and the products contained therein may be preserved for a long time in the best conditions, that is, in the same conditions in which it was packaged.
  • the new container is obtained by means of a low cost mass production process, which requires only the die cutting, creasing and folding of one or more sheets.
  • the container is practical to use and makes it possible to dispense the exact quantity of product required, with no need to use scales, and furthermore it does not require the transfer of the residual unused product in other sealed containers.
  • the container may also usefully indicate the correct quantities of product necessary for a given purpose. In the case of pasta, for example, it will be possible also for unskilled consumers to dispense the exact quantity of pasta sufficient for an average consumer.
  • Figure 1 shows the development of the die cut sheet (P6) for making the new container (S6) with regular hexagonal base, wherein the lower hexagonal folding part serves as the bottom (F) and a single upper hexagonal folding part serves as the cover (C).
