  • Patent number: 11884434
    Abstract: Shown and described are a packaging machine and a method for producing a packaging unit from a packaging sleeve group comprising a plurality of flat folded, upright packaging sleeves, and an outer packaging. It is provided that the packaging machine comprises at least one conveyer unit for conveying the packaging sleeve group in a conveyor direction perpendicular to the longitudinal extent of the packaging group and at least one outer packaging unit for preparing an outer packaging-shaping sheet material in a base position, and in that, seen in the conveyor direction behind the sheet material in the base position, a sealing unit is provided for sealing of the sheet material enclosed in the packaging sleeve group.

  • Patent number: 11845598
    Abstract: There is illustrated and described a bundle (14) comprising packaging sleeves (10) and an outer packaging (15), comprising: a plurality of packaging sleeves (10) of a composite material, and an outer packaging (15) which surrounds the packaging sleeves (10), wherein each packaging sleeve (10) has a front side (12) and a rear side (13), wherein the front side (12) and the rear side (13) of each packaging sleeve (10) are separated from each other by means of folding edges (F), along which the packaging sleeve (10) is folded flat, wherein each packaging sleeve (10) has two openings which are arranged on opposite sides of the packaging sleeve (10), and wherein each packaging sleeve (10) has a longitudinal seam (11) which connects two edges of the composite material to form a circumferential packaging sleeve (10). In order to enable a space-saving, cost-effective and reliable transport of packaging sleeves (10), it is proposed that the outer packaging (15) be produced from a plastics material film (17).

  • Patent number: 11117341
    Abstract: A method for precursor production includes A) providing a multitude of container precursors, and in each case a) providing a sheet-like composite, having a first longitudinal edge, a further longitudinal edge and, from the first longitudinal edge to the further longitudinal edge: i. a first longitudinal crease, ii. a second longitudinal crease, iii. a third longitudinal crease, and iv. a fourth longitudinal crease. The method includes b) producing a first longitudinal fold characterized by a first internal angle along the first longitudinal crease and a third longitudinal fold characterized by a third internal angle along the third longitudinal crease; c) producing a second longitudinal fold characterized by a second internal angle along the second longitudinal crease and a fourth longitudinal fold characterized by a fourth internal angle along the fourth longitudinal crease; d) contacting and joining the first longitudinal edge to the further longitudinal edge thereby obtaining a longitudinal seam.

  • Patent number: 11065824
    Abstract: The invention relates in general terms to a device for production of a packaging precursor, wherein the packaging precursor consists to an extent of at least 80% by weight, based on the packaging precursor (1000), of a sheetlike composite, wherein the sheetlike composite includes: i. a composite plastic layer, ii. a composite carrier layer, iii. a first composite edge region, iv. a second composite edge region, wherein the device includes, as device constituents in a flow direction: a) a flat transport unit designed to transport the flat sheetlike composite, wherein the transport unit includes a transport surface designed to bear the composite; downstream of that b) a first heating unit designed to heat the first composite edge region, where the first heating unit includes energy release segments; downstream of that c) a contacting unit designed to bond the first composite edge region to the second composite edge region; wherein the first heating unit is designed to release energy in the flow direction.
