Definitions

  • the invention relates to a cardboard packaging with a body part forming the side surfaces made of gas-tightly coated cardboard on the inside and a base part and a cover part, which have a main part and tab parts on its edge and which extend into the body part.
  • Such cardboard packaging is to be used for the gas-tight packaging of liquid, pasty, granular or powdery products or the like.
  • Many cardboard packaging that is intended to fulfill this purpose has cardboard or cardboard materials coated on both sides or with a sealable coating.
  • the cardboard blank is next to the side flaps and the cardboard lid, which requires a very high amount of material.
  • the corner joints of these packs are joined over pre-folded corner flaps by two to three times the thickness of the cardboard overlap using a heat sealing or gluing process, so that this multiple overlay inevitably creates leaks at the upper edges of the main part of the box.
  • leaks continue to occur in the corners of the carton due to non-flush connecting edges.
  • a further known possibility of keeping a product storable for a longer period of time is the known outer carton packaging, which is followed by known methods of erecting the carton and closing the bottom flap by gluing or folding or the like loaded with an airtight sealed plastic or plastic composite bag filled with the product and then closed as previously described.
  • This carton is very material-intensive and also very labor-intensive when it comes to packaging.
  • Cardboard material coated on both sides as is also used in beverage packaging to achieve tight packaging, naturally also has the disadvantage of high production costs.
  • a seal is achieved by means of a very expensive material by means of a very complex two-sided sealing, especially in the bottom area of the package, which leads to considerable costs in the considerable quantities of these packages.
  • the body part is made of cardboard and is only gas-tightly coated on the inside.
  • the bottom and the lid part are made of aluminum.
  • This cardboard packaging can therefore not be disposed of in an environmentally friendly manner due to the high metal content and is also very expensive because of this metal content.
  • One possibility of modifying this packaging in such a way that the lid and base part can also consist of cardboard is expressly denied (DE-U-80 03 179; page 5, lines 19 to 22).
  • the sealing in the base and lid area makes use of the excellent flow properties of aluminum when pressure is applied with the corresponding locking jaws.
  • the object of the invention is to create a reliable gas-tight cardboard packaging of the type mentioned, which is environmentally friendly and can be produced inexpensively.
  • the use of aluminum foils for the bottom and lid should be avoided.
  • the solution according to the invention is that the bottom part and the lid part also consist of cardboard coated gas-tight on the inside, that the tab parts are connected by gusset parts, that the tab parts between the main part of the bottom / lid part and the edge of the fuselage part on the inside thereof with the fuselage part are connected and that the fuselage part is formed on one side surface completely overlapping two layers.
  • the base part and the lid part do not consist of aluminum, but also of coated cardboard.
  • the tab parts are connected to one another by gusset parts, which are pressed together after the cover part and the bottom part have been introduced into the fuselage part in order to obtain an optimal seal here in the corner area.
  • the main part drawn rectangularly there
  • the flap parts are folded over in relation to the main part and lie against the inside of the fuselage part. In contrast to the prior art, this also makes it possible to produce the base part and lid from cardboard without wrinkles forming, which would cause the closure to leak.
  • the gusset parts are relatively small.
  • they occupy a space that is significantly smaller than the space that is delimited by the connecting line of the outer corner points of adjoining tab parts.
  • the gusset parts consist of two interconnected triangles, each of which is connected to a tab part on its outer sides.
  • the various cardboard parts could be connected by gluing.
  • the inside coating of the cardboard material is heat-sealable, so that both the fuselage part can be joined together using heating stamps, and that the bottom and lid parts can also be attached to the fuselage part using this technique.
  • the tab parts have extensions which grip around the edge of the fuselage part and are fastened to the outside thereof. This increases the stability in the base area and lid area. This also makes the seal even better and safer.
  • the cardboard packaging is expediently provided with a tear-open tab, the predetermined breaking lines of which are arranged outside the coating.
  • This pull tab can be provided in particular in the lid. In this way you have easy access to the goods that are packed in the cardboard packaging.
  • the carton packaging tapers upwards or downwards, the top / bottom of one carton can be inserted into the bottom recess / lid recess of another carton, so that stable stacks are obtained.
  • the cardboard packaging further has a removable and re-attachable cover that is slipped onto the cover part.
  • cardboard packaging can be closed again at any time with this additional lid in order to protect the goods contained therein from spoilage.
  • the thickness of the coating is advantageously approximately 14 ⁇ . This results in less than 5% plastic content, so that the packaging meets the conditions of the "green dot". It is even more advantageous if the coating has a thickness of only approximately 12 ⁇ m with a cardboard thickness of approximately 250 g / m 2 .
  • the cardboard blanks are provided with creases or impressions on the folding lines provided.
  • a thin plastic film coated with aluminum metallization has proven to be a particularly suitable gas-tight coating.
  • the cardboard blank for the body part 1 has large side panels 3, a small side panel 4 and two side panels 5, which, as shown in FIG. 2, are glued to one another over the whole area or connected by heat sealing are.
  • a body part 1 is obtained which can be folded up for transport to the filling station.
  • This fuselage part has a rectangular cross section, but can of course also have a square cross section or other polygonal cross section.
  • cover and bottom parts 2 are used, as shown in Fig. 3.
  • the cover and base parts 2 have a rectangular main part 6 shown in the figures and tabs 7 adjoining them on all sides.
  • the various fields of the blank or main part 6 and tabs 7 are separated by grooves 8, which enable folding.
  • triangular gusset parts are provided between the tab parts, which are connected with their long sides to the adjacent tab and are connected to one another with their short sides. These gusset parts 9 are folded inwards when the bottom / cover part 2 is inserted into the body part 1. The gusset parts 9 then protrude on the inside in the corner area and are pressed together by the pressing tools in the corner area, a gas-tight corner connection then being created in connection with the adhesive / heat sealing.
  • FIG. 8 shows a somewhat different embodiment of the base / cover part 2, in which the tongue parts 7 are connected to outer tongue parts 10, which are folded and fastened around the edge of the opening of the body part 1, as is shown in FIGS. 10 to 12 is shown.
  • This not only provides additional strength, but also additional sealing.
  • a cover 11, shown in broken lines, can be slipped onto the cover part 6, with which the packaging can be closed again when the cover part 2 has been opened. The packaging through the lid 11 is then of course no longer gas-tight.
  • Both embodiments are closed according to the method steps shown in FIGS. 13 and 14 on the bottom part and after filling also on the cover part.
  • an inner jaw 12 with recesses 13 at the corners inside is introduced into the end region of the body part 1 and the lid / base part 2, whereupon pressure is exerted from the outside by jaws 14 in order to produce the connections in the edge region of the base / lid. If adhesive is applied, the outer jaws 14 press the areas against the inner jaw 12. In the case of heat sealing, additional heat is supplied.
  • inner jaws 15 and outer jaws 16 are arranged in the corner regions, through which the corner connection is then formed by the corresponding sharp corners and in particular the gusset parts 9 are pressed together in order to achieve the tight connection here to obtain.
