Definitions

  • Roll of continuously peeled composite film can be produced.
  • the sealing seams that are present in the edge region of the flat bag cause the side regions of the flat bag to protrude from the packaged body like a fin. This requires some space around the packaged body, such as around the battery "case", which must be available for packaging and not for other components.
  • transverse sealing seams are very stiff. Since these transverse sealing seams give only a little when the upper longitudinal sealing seam is sealed, an uncontrolled formation of folds occurs when the upper longitudinal sealing seam is sealed, which can lead to leaks and which in particular also increases the space requirement for such a battery with folds.
  • the invention has for its object to provide a way to provide cuboid bodies with a tightly fitting packaging or to provide existing flat batteries in the form of cuboid bodies with a housing that the electrolyte-soaked electrochemical Encloses cells of each battery as closely as possible.
  • the storage of a cuboid body in a flat bag has the advantage, in particular when the cuboid body is a flat battery containing cells soaked with electrolyte, that very economical flat bag machines can be used. In connection with batteries, thermoforming machines no longer need to be used to manufacture battery cases.
  • the turning over of one or both side areas of the flat bag onto one or the two bag walls means that the cuboid body sitting in such a package takes up little space overall; Fin-like sealing seam areas of the flat pouch that protrude laterally from each side can be "removed". In the area of the top longitudinal seal seam, the side area can be folded in before the longitudinal seal seam is applied.
  • the folded-over side areas of the flat bag can be glued to the bag wall or attached to the bag wall (s) with an adhesive strip, which can be, for example, an adhesive label.
  • This transverse sealing seam which is additionally present in the side area, is preferably not led all the way up, over the entire bag wall, but ends below the top of the stored body. This facilitates the attachment of the upper longitudinal sealing seam, with which the bag is closed at the top, in the upper corner area on the side.
  • a side inner fold can be provided in this upper bag corner in the upper corner area of the bag, with the side area folded over. If the upper longitudinal sealing seam is then applied and the bag is closed at the top, there are no bag areas which protrude laterally from the clearance profile of the packaging enveloping the body.
  • Fig. 1 is a perspective view of a
  • FIG. 2 shows a partial area separated from the composite film according to FIG. 1, namely a flat bag which is open at the top and prepared for storing a battery body,
  • FIG. 3 shows an illustration of a battery body partially inserted into the flat bag according to FIG. 2,
  • FIG. 5 shows a representation similar to that of FIG. 4, with fold lines arranged directly next to the stored battery body in the bag walls of the flat bag,
  • FIG. 6 shows a representation similar to that of FIG. 5 with further transverse sealing seams provided in the area of the fold lines
  • FIG. 7 is a bottom view of the object of FIG. 6,
  • FIG. 8 shows a bottom view of the object from FIG. 6 with folded-over side areas which are alternately folded over onto the bag walls,
  • FIG. 8.1 shows a representation similar to that of FIG. 8 with side regions folded over onto the same bag wall
  • FIG. 9 is a perspective view of the bag according to FIG. 10 is a perspective view of the object of FIG. 9 with side inner folds present above the embedded battery body in both upper outer regions of the flat bag,
  • FIG. 10.1 is a partial representation of FIG. 10, with a side inner fold not present,
  • Fig. 11 is a perspective view similar to that of Fig. 10, with an additional top applied
  • FIG. 12 is a view along the section 12-12 of FIG. 10.
  • a one-piece composite film web 10 is shown, which is for example continuously pulled off a roll and which is provided in its bottom region 12 with a W-shaped bottom fold 14.
  • the web 10 thus has two opposing bag walls 16, 18.
  • transverse sealing seams 22 are made along the web 10 at a distance 24 and the two bag walls 16, 18 are welded to one another.
  • a plastic strip 26, 28 is fastened in the upper region of the two bag walls 16, 18.
  • the two plastic strips 26, 28 protrude above the upper edge 30 of the respective bag wall 16, 18.
  • These two plastic strips 26, 28 can be the lower parts of a resealable strip known per se. Resealable strips are known for resealable flat bags. In the present case, however, they serve not to close a flat bag 20, but to protect the upper edge 30 against unintentional contact with the connecting tabs 34 which protrude from a battery body 32 at the top.
  • the composite film web 10 is cut in the area of its transverse sealing seams 22. Individual flat bags 20 then result. After opening the two bag walls 16, 18, a battery body 32 is inserted into a bag 20 from above. This battery body 32 consists of electrochemical
  • connection lugs 34 look out from the battery body 32 as anode and cathode lugs.
  • the bottom 35 of the battery body 32 presses the W-shaped bottom fold 14 flat, so that the bottom region 12 of the flat bag 20 lies flat against the bottom 35 of the battery body 32 in the area of its bottom fold 14, as is the case here 4 and the following, in particular FIGS. 7 and 8.
  • the two left and right side areas 38, 40 containing the transverse sealing seams are then pressed together by folding lines 42, 44 and the embedded battery body 32 is also framed laterally by the side areas 38, 40 (FIG. 5).
  • transverse sealing seam 46.1 or 46.2 is then applied immediately next to the fold line 42 or 44.
  • these transverse sealing seams 46.1, 46.2 have no lateral connection to the respective outer transverse sealing seams 22.
  • sealing seams 46.1, 46.2 extend to a height 48 which lies below the upper edge of the battery body 32, which is characterized by the height 50 (FIG. 6).
  • the longitudinal sealing seam 56 (FIG. 11) that is to be applied later after the side regions 38, 40 have been turned over does not overlap with regions of the inner transverse sealing seams 46.1, 46.2.
  • the two side areas 38, 40 are then alternately folded over onto the two bag walls 16, 18 (FIG. 8) or onto the same bag wall 16 (FIG. 8.1) and fastened to the bag wall or bags.
  • the attachment can be carried out by means of an adhesive or by means of adhesive tapes or adhesive labels holding the side areas 38, 40 together with the relevant bag wall 16, 18.
  • a side inner fold 54 is provided in the upper lateral corner region of the flat bag 20. This inner side fold 54 is present above the height 50 (FIG. 6). If this inner side fold 54 is not provided, the corresponding upper corner area 52 of the flat bag 20 protrudes laterally outwards (FIG. 10.1).
  • a longitudinal sealing seam 56 is then applied in the upper region of the flat bag 20, directly above the inserted battery body 32, and is also present in the region of the two lateral side inner folds 54.
  • the flat bag 20 is sealed gas-tight at the top by this longitudinal sealing seam 56.
  • the invention relates to a cuboid body, which is stored in a tightly fitting package.
