Definitions

• in-form labelling a pre-printed label is placed in the deep drawing tool, following which the heated plas- tics is e.g. sucked into shape and fuses with the label. This process is expensive, because the labels have to be made and handled separately - including being placed in the deep drawing tool .
• GB 2,018,227 discloses a container for take-away foods.
• the package is punched from a plastics or metal sheet and folded into shape, said shape being maintained as the sides of the container have projections which are caused to engage at the folding.
• the recovery property of the plastics keeps the container in shape.
• the folding can only be partial and without sharp folds . This is due to the same recovery property of the material.
• the sheet can be bent max. 180 degrees. At 180 degrees the two sides of the, fold meet. To achieve a permanent deformation with sharp folds, the material would have to be bent considerably more, which, of course, is not possible for physical reasons. Therefore, the container has rounded sides and soft folds.
• the patent does not state that there may be a lid for the container.
• a lid/wafer would not form a tight seal either, as the folds are too inaccurate, and thereby also the shape of the opening of the container is inaccurate. So even if the overlaps were glued, and an attempt was made with a lid, then the container would not be suitable for anything but storage of the contents for minutes, rather than hours, let alone days.
• GB 2,273,093 discloses a container which is made by folding of plastics, and where the sides have projections which are caused to engage at the folding, whereby the shape is retained and fixed owing to the recovery property of the plastics.
• the figures of the document show the folds as sharp creases, which is not possible with known plastics types by ordinary folding. As mentioned above, this would require bending beyond 180 de- grees. The upward opening gets very inaccurate, and therefore the container is not suitable for the application of a tight-sealing lid/wafer. Thereby, it is not suitable for the storage of contents that may not be exposed to the ambient air, which is the requirement e.g. with many types of processed foods.
• An object of the invention is to provide a package of a plastics sheet material as well as a method of making such a package, which is suitable inter alia for nutri- tious and non-nutritious products, including foods and beverages or the like, wherein the package may be provided with a print before the package is formed, and wherein the forming may take place substantially by cold forming so that the print is not affected.
• a further ob- ject is to provide a method and a package, wherein the forming may take place substantially by cold forming, and wherein the package is suitable for receiving a tight- fitting lid/wafer.
• Another object is to provide a method and a package wherein it is not necessary to apply a label or the like and/or use another subsequent cost-adding process.
• Still another object is to provide a method and a package, wherein the package protects the contents better than known board-based packages, which may improve the life of the contents, both in total and on the shelf at the shop, and/or which may mean that the share of preservatives in the contents may be reduced.
• a further object is to provide a method of making a package where the package need only be "erected" (folded and joined) imme- diately before it is filled.
• Welding is taken to mean a heating whereby the two ends or two parts fuse together, or that an applied glue is activated, so-called hot gluing, or a hot melted substance is applied that adheres and/or seals the ends or the parts together, or another similar process.
• a collar may comprise a formed edge, face, side or a termination which is suitable for cooperating with a lid, package, wafer or other similar closing means.
• a collar may be used for increasing the strength, rigidity and/or reproducibility of a package, a lid, etc.
• the folded package may comprise at least a barrier layer in the sheet, which means that in some types of packages there is no need for additional protection against sun light, water and oxygen. This protection is simply incorporated in the sheet from which the package is folded. Moreover, the part of the sheet remaining after punching may be reused without any problems, which has so far not been the case with residual material from e.g. thermo- forming of packages . In the traditional methods of making a package, residual material may also be reused, but only if there is no ink on the sheet since this may contain free radicals.
• the package may include a collar intended for a snap-in lid, and in still another embodiment, be intended for a press lid.
• the package may thereby be used together with all common types of lids.
• the at least one layer to which inorganic powder material has been added may constitute at least 75% of the total thickness of the sheet.
• a relatively large amount of powder may be achieved, which reduces the price.
• the amount of powder is favourable for the reproducibility of the package.
• the amount of inorganic powder material may constitute at least 20 per cent by weight of the at least one layer, thereby making the sheet foldable .
• the amount of inorganic powder material may preferably constitute at least 50 per cent by weight of the at least one layer, which is particularly favourable for the fold- ability of the sheet, just as shrinkage is reduced.
• Fig. 5 shows a section of a folded package with a snap lid
• Fig. 6 shows a section of a folded package with a press lid
• Fig. Id shows a sheet which consists of a single layer 3 of plastics as well as an integrated barrier layer 7, which may e.g. be black pigment, black plastics, aluminium foil, etc.
• the sheet may be made e.g. by lamination or by co-extrusion and may comprise as many or as few layers as is required by the actual packaging need.
