ABSTRACT:
The invention relates to a package for particulate goods, especially for a group of (cuboid) individual packs, especially soft packs, comprised of a pack part (main pack/basic pack/carton) and at least one cover for open side faces of the pack part, which consists of thin packaging material, especially paper. The invention furthermore relates to a process and an apparatus for making such packages.
The invention deals with a material-saving package which, in addition to this, simplifies handling. The package is particularly suitable and intended for the accommodation of a group of individual packs. These packs may, in particular, be soft packs, and thus individual packs with a content of articles made of cellulose pulp or cotton wool.
The invention is based on the object to propose a package which has sufficient dimensional stability in spite of a reduced material consumption and, moreover, ensures an easy access to the pack contents, so that the package can also be used as a display for sale.
To attain this object, the package according to the invention is characterized in that the supporting element is U-shaped with a bottom wall and upright, mutually confronting side walls which are confronted by open sides which adjoin one another in a U-shaped manner, the bottom wall and the side walls being provided with connecting members which project into the region of the open sides, namely bottom strips, lateral strips, and transverse strips for fixing a U-shaped cover for the open sides on the outside of the strips by adhesive bonding or the like.
The supporting element made of cardboard or the like forms the dimensionally stable supporting member of the package with a bottom wall and two mutually confronting side walls. These side walls are provided with transversely directed edge strips which extend in the plane of the open side faces and are connected to one another. This results in an additional stabilization of the three-dimensional structure. The flange-like lateral strips furthermore serve for fixing the one-piece blank of the cover on the outside of the edge strips by adhesive bonding.
Consequently, the package according to the invention consists of two blanks. In the production of the package, a cardboard blank for the supporting element is first folded around the pack contents in a U-shaped manner, and then the strips are folded into the plane of the open sides and connected to one another. Afterwards, the cover is also folded around the pack part by a U-shaped folding in the region of the open sides, and connected to the strips.
In the packaging of soft goods, especially soft packs, the pack contents are stabilized during the U-shaped folding of the cardboard blank by guides, especially by a movable folding sleeve which at least partially surrounds the pack contents and ensures the dimensional stability of the pack contents during the U-shaped folding of the cardboard blank. The folding sleeve is pulled out of the partly folded package after the U-shaped folding of the cardboard blank or after erecting the side walls.
In a separate folding cycle, the paper blank for forming the cover is folded over the supporting element and the pack contents in a U-shaped manner, specifically in the course of an upward movement of the supporting element.
The apparatus according to the invention for producing a package comprises a folding station for the cardboard blank and a further folding station for the cover. In the first-mentioned folding station, the pack contents with the blank are first moved downwards to carry out first folding steps and then horizontally to complete the folding of the supporting element. The cover is then laid against the supporting element by an upward movement of the partly finished package. The ready package may then be situated at feed level.
