Definitions

  • the present invention relates to a method and an apparatus for airtight packaging of small-sized articles having a substantially rectangular bottom surface.
  • Airtight packaging is predominantly realized according to the flow-pack principle. This method has the advantages that a very high tightness of the packaging can be achieved. At the same time, it is a fairly simple and highly efficient packaging process. In addition, a large variety of products can be packaged in this way. The disadvantage, however, is that such primary packaging can only be further packaged in certain secondary packaging and the product form is no longer recognizable.
  • the small piece articles are usually wrapped in a tubular fashion with an airtight and sealable package so that the package protrudes from both sides over the bottom surface. Under formation of longitudinal and transverse sealing seams, the packaging is then sealed airtight around the article.
  • a disadvantage of these solutions is that the appearance of the bottom fold is unattractive, since the sealed tips are folded in the last packaging step on the ground and possibly protrude due to the elastic restoring forces of the packaging. Because the packaging is not particularly close to the article due to the packaging material projecting beyond the bottom surface, secondary packaging without additional aids is hardly possible. In addition, these packaging tips also have so-called speed cameras, by the inside of the packaging is visible. These disadvantages were compensated by folding a paper band around the airtight primary package. This in turn is very cost-intensive and efficiency-reducing.
  • a disadvantage of the known solutions such as EP 2 688 805 B1 However, the increased consumption of packaging and the difficulty to betechnikstelligende tightness of the packaging, as with certain format dimensions in the corners no secure coverage of the individual seals can be guaranteed.
  • the invention is based on the object, starting from the known from the prior art solutions to develop a method and apparatus for airtight packaging stiiitziger article with attractive appearance and high density of the (primary) packaging at a lower packaging consumption, so that a secondary packaging without additional aids such as a band is possible.
  • the packaging supernatants are processed identically on both sides of the bottom surface, although different processing of both packaging supernatants are possible.
  • an airtight packaging of small-sized articles with a substantially rectangular bottom surface can be accomplished particularly close to the contour and with a lower consumption of packaging material.
  • the solution of folding away the packaging supernatants since no residues remain in the machine.
  • the remaining packaging can be fixed to the ground. This is made possible, for example, by applying hot glue dots before the last wrinkles are applied to the floor and pressed.
  • small article in the context of this invention refers to the articles to be packaged. This means intended small-sized food in the first place. These include confectionery made of chocolate or caramel, but also bouillon cubes or the like. However, it is also within the scope of the invention to package small-size consumables such as washing or Spülmaschinentabs with the inventive method.
  • the maximum edge length of such "small piece articles” is preferably 15 to 150 mm or less.
  • substantially rectangular bottom surface is primarily intended to facilitate the circumscription of geometric relationships in packaging and should not be construed as limiting with respect to articles of differently shaped bottom surface.
  • a rectangular bottom surface is bounded by pairs of parallel longitudinal and transverse edges.
  • the bottom surface does not exactly a rectangle, because for example the corners between the longitudinal and transverse edges are rounded and / or the longitudinal and transverse edges not exactly parallel to each other run.
  • shape deviations of the bottom surface of an ideal rectangle the invention is to apply to all small-sized articles application in which an application of the invention is technically possible.
  • the article with a substantially rectangular bottom surface at least approximately the shape of a cube, a cuboid, a pyramid or a truncated pyramid.
  • at least one, several or all of the side surface (s) of the article, including the bottom surface are planar, concave or convex.
  • the Bottom surface is preferably the largest side surface of the article.
  • the bottom surface and the side surface opposite the bottom surface generally form the two largest side surfaces, while the end sides or end surfaces adjoining the transverse edges form the two smallest side surfaces.
  • the terms longitudinal edge and transverse edge serve primarily to facilitate the description of the steps of the method according to the invention and do not imply geometrical dimensions.
  • the bottom surface defining longitudinal edges of the article are preferably longer than the transverse edges bounding the bottom surface, the terms used herein should not be construed as limiting.
  • the article with the packaging material is preferably wrapped in a fold over the bottom surface in a circumferential circumferential direction, so preferably the tube axis parallel to both the bottom surface bounding longitudinal edges of the article and the packaging on both sides transverse or perpendicular to the circumferential direction on the respective bottom edge bounding the transverse edge of the article protrudes.
  • the tube axis runs parallel to both transverse to the bottom surface limiting transverse edges of the article and protrudes on both sides over the respective the bottom surface bounding longitudinal edges of the article.
  • the inventive method is therefore not limited to a specific orientation of the article within the packaging.
  • the "seal” preferably includes longitudinal and transverse sealing seams that extend along and / or parallel to some longitudinal and transverse edges defining the bottom surface of the article to airtightly close the package.
  • the sealed seam is preferably formed between two sections of the packaging, which are preferably opposite to the inside.
  • the strip-shaped packaging material is arranged in a circumferential direction, which extends over the bottom surface of the article around the outer circumference of the article, so that the packaging material completely encloses the article in tubular form and fits close to the inside of the article, so that the open Ends of the tube-shaped packaging projecting on both sides over the bottom surface to form packaging supernatants.

  • the projection of the fin in the circumferential direction is preferably half the width of the bottom surface, measured from the bottom surface bounding edge along which the fin is formed, to the opposite, the bottom surface bounding edge.
  • a different supernatant of the fin is also conceivable.
  • the rear folding edges at the transition between packaging supernatant and fin arise with folding of the fin on the bottom surface of the article.
  • the front fold edges arise due to the geometry of the article when folding the end faces.
  • the continuous sealing seam is preferably composed of different individual sealing seams.
  • a longitudinal sealing seam and two transverse sealing seams are produced independently of each other, which overlap at the corners due to a folding process carried out in the meantime.
  • Each transverse sealing seam is preferably produced only in the state after folding the longitudinal seam fin on the bottom surface of the article.
  • Sub-steps B1 (B1a, B1b) to B6 can be carried out in the specified order or in a different order.
  • the sub-step of forming at least one transverse sealing seam (B1 b) is preferably carried out only after the sub-step B3, B4, B5 or B6, in order to ensure the desired tightness of the sealed seam, since the sealing seam only after the folding of the fin on the bottom surface of the article can be performed over the entire transverse side or width of the packaging supernatant.
