Definitions

  • the invention relates to a material and energy-saving packaging method, in particular for powdery products or mixtures thereof, and a resulting packaging, in particular in the form of sealed from three sides sealed edge bag, from a suitable, air-impermeable packaging material, such as a film, a composite material or the like , in which the content may be stored for a predetermined time, wherein the opening of the packaging and the removal of the contents takes place in any manner known from the prior art, according to the preamble of claim 1.
  • Such packaging and packaging methods are known in particular from the food industry, for example from the DE 29 32 236 A1 , which relates to an apparatus for producing three-edge sealed-edge bags and discloses a generic method. According to this teaching, powdery or free-flowing products are packaged airtight, so that they are expediently protected over the entire intended storage time, mainly from the action of light and moisture.
  • This sealed-edge bag has dimensions of 8 cm x 10.5 cm, with a content of, for example, 10 grams.
  • the total consumption of a high quality packaging material for this package is 161 cm 2 , which is a disadvantage.
  • the powdered mixture for the preparation of hunter pot 30 grams of content, the company Maggi, packed in a sealed-edge bag with dimensions of 13 cm x 15 cm.
  • 390 cm 2 of expensive packaging material is necessary to package this small amount of the mixture, which is a disadvantage.
  • the current packaging methods are carried out on packaging equipment, where the packaging material on a hollow cylindrical dosing, slidably moves along its longitudinal axis and his packaging designed areas are conveniently closed by means of sealing edges, for example, after a slidable dosing screw, with a closing head, this has previously filled.
  • US Pat. No. 3,306,002 relates to an apparatus and method for filling bags with powdery or granular products.
  • GB 2 174 970 A relates to the packaging of products into individually separated, vacuum-sealed bags of flexible material.
  • US 4 962 627 A discloses a method for compacting a powdered cosmetic preparation.
  • the object of the present invention is to further develop the packaging methods known from the prior art and resulting packages, in particular for packaging powdered products or the like, in such a way that the necessary surface area of a suitable packaging material can be reduced by up to 50%, without the resulting formable packaging has a lower quality.
  • Another object of the invention is to propose such a type of packaging that the storage time of the so packaged products is extended.
  • a packaging system of at least one upper part, which is equipped with a plurality of upper part housings, and at least one lower part, which is equipped with a plurality of lower part housings is, consists, and that the upper part and the lower part must be movably arranged to each other and to the sub-housings, and that the upper part are joined to the lower part so that the upper and lower part housings continuous but divisible interiors must form, and that each upper part housing each have a metering device and an axially movably arranged in its interior compression piston is assigned, while each lower part housing also an axially movable fixing and extrusion piston is assigned, and that in the starting position of the packaging system itself the compression piston above the feed opening of the metering device must be located, while the feed opening in turn must be always higher than the surface of a loosely metered product, and that the current position of the fixing and Auspresskolbens in the lower part housings to
  • the compression piston must be made so permeable to air but product impermeable that always the desired compression / compression of a product is achieved.
  • the metering devices must assume such positions after the metering operations that the cooperating with them compression piston close to these but not touching move, and thus take into account all the particles of a product in the compression process.
  • each metering device depending on the loose volume of a product to be compacted, must always be positioned so high that even its largest metered amount of a loose product to be processed here is always below the lower one Edge of its feed opening is located.
  • the arrangement of a metering device on the housing is to be made such that the respective portions of a product to be compacted in the separable internal spaces, which can be formed from upper part housings and lower part housings, must be completely detected by the compression pistons during each compression process.
  • a packaging system for example, 80 packs or more can be produced simultaneously in the manner described above, wherein, for example, if a packaging system provided here operates at 5 cycles / minute, which enormously reduces its wear, nevertheless produces approximately 400 packs / minute can.
  • a packaging system according to the invention can operate without problems at 10 cycles / minute, whereby the amount thus produced can increase to about 800 packages / minute, which are particularly important features and advantages of this invention.
  • the drive and the control of the individual sequences according to the invention in particular centrally and so between the housings, for example, if a packaging system is equipped with 40 upper and lower part housings, is advantageous if you Drive and its control, for example, between 20 and 21 sub-housings is arranged in such a way that the distance between which remains as small as possible in order to reduce the transmission of the necessary torques.
  • the invention provides that two adjacent sealing edge bags are to be designed as a unit, the interior of which must be airtight separated from each other, so that after a convenient removal of a product portion, the other still airtight remains closed.
  • Contents of this invention are also sealed edge bag designs that are as a double-pack unit, for example, up to 30% larger than the current, simple known from the prior art.
  • a better readability of Hints take place and still can be saved in the production of the edge seal bag according to the invention still about 20% of packaging material and energy.
  • Another very important feature of the invention is that it makes superfluous that some known from the prior art packaging with the now common reference “quantity due to technical reasons” or a similar, comparable, must be provided, which usually irritates the end user when they find plenty of empty space in an original sealed packaging.
  • the compression pistons must always be located above the feed openings of the metering devices in the upper part housings of the packaging equipment during the metering of a product into the interior spaces, the fixing and extrusion pistons, depending on the final volume of the later submitteddrückbaren, compacted contents of this have adopted adapted positions in the interiors of the lower part of the housing packaging system.
  • the intended quantities of loose product to be packaged are to be metered so that the whole portions of a product fall into the assembled internal spaces of the upper and lower parts of the packaging plant must be connected to each other dust-tight, and then by means of compression pistons, on the one hand must have air-permeable structures, but on the other hand, the products must compact appropriately, and these are to be moved until the products are in the lower part housing of the lower part of the packaging system relocate, where in these final positions the products must already be compacted as intended, so that the upper part of the packaging plant together with the upper part housing and metering devices of the lower part of the packaging plant is so far to relocate that the compacted contents Now completely in the interiors the lower part housing of the packaging system are located, wherein the level is, for example, about 2 mm below the openings of these, and that they are not to move thereafter.
  • the lower part housings in the lower part of the packaging installation are covered with a suitable packaging material section from three sides, for example from a supply roll, so that the bottom, which can be formed later, of the sealing edge bags is to be positioned at the top and the freely accessible openings of the lower one Partial housing covered, and that, after an appropriate separation of the thus positioned portion of a supply roll, between the adjacent lower part housings of a lower part, respectively vertically arranged, permanent sealing edges, mainly double width than later provided, according to the division of the invention these are to be formed in single or double units, which must extend over the entire height of the blanks, regardless of what number of packages are to be formed in one operation.
  • the lower part of the packaging plant together with the packaging covering the housings, which are connected to several sub-packaging material section, must be rotated about its transverse axis, in particular by 180 degrees and fixed in this position, so that the openings of the interiors now after stay downstairs.
  • the product treatable with this packaging method can also be composed of several constituents, the shape of which is not adversely affected by a compaction process, such as noodles in a powdery mixture as an instant, or the like.
  • the packaging system according to the invention can cooperate with any metering devices, if they are mounted on their upper part housing so that the intended amount of content can be repeatedly dosed into their assembled interiors, and that they are so high These are arranged so that the largest possible quantities of the contents to be processed here, after the appropriate filling of the interiors, are always below the lower edges of the metering devices to guarantee their appropriate densities.
  • Another important feature of the invention is that the fixing and Auspresskolben need not have holes for air passage, since due to a prior removal of the lower part of the housing prefabricated packaging part each an air gap is formed, the subsequent removal of the piston a guarantees clean separation of each product from the particular suitably coated fixation and extrusion piston.
  • the compression flasks are suitably coated to guarantee an even faster and cleaner separation of a product to be packaged from them.
  • This coating must always have such properties that on the one hand it remains chemically neutral with respect to the product groups to be packaged, on the other hand its friction with the interiors of the housings must be as low as possible in order to suitably reduce their wear, which is also very important for this invention ,

    - après une séparation adéquate de la partie supérieure (2) de la partie inférieure (3), les logements de partie inférieure (15) orientés avec leurs ouvertures (12) vers le haut, notamment verticalement, peuvent être recouverts d'une section de matériau d'emballage appropriée (10) de sorte que leur section centrale recouvre les ouvertures (12) des logements de partie inférieure (15), et que la section de matériau d'emballage (10) peut être reliée durablement dans les espaces intermédiaires (29) entre les logements de partie inférieure voisins (15), au moyen d'un dispositif approprié, de manière étanche à l'air et positionnée verticalement, à des bords scellés verticaux (11) d'une double largeur, et que
    - après un retrait utile du dispositif à bords scellés, les logements de partie inférieure (15) peuvent être orientés d'environ 180 degrés vers le bas de sorte que leurs ouvertures (12) avec les fonds des emballages partiels (30) adoptent la position la plus basse, et que
    - les logements de partie inférieure (15) peuvent désormais être retirés entièrement vers le haut des emballages partiels (30) avec les pistons de fixation et d'injection fixes (5), moyennant quoi une fente d'aération apparaît à chaque fois, laquelle garantit un retrait subséquent, ne perturbant pas la colonne de produit (31), des pistons de fixation et d'injection (5) des emballages partiels (30), et que
    - les emballages partiels (30) peuvent ensuite être scellés de manière étanche à l'air et durable au moyen de la formation d'un bord scellé supérieur continu (18), et
    - la série des emballages ainsi disposés les uns derrière les autres peut ensuite être divisée en emballages individuels (32) ou emballages doubles (33).
