Embodiment Construction

[0025] figure 1 A tubular packaging sleeve 1 is shown as packaging material for future beverage packaging. A packing sleeve 1 of this type is produced with a longitudinal seam from a cut, which is not shown. It can be in any position, for example in the central area or on one of the edges 2 . Furthermore, the crease line 3 can be considered to be used to fold the base and gable area (head area) of the future package.

[0026] figure 2 Shown is a nozzle element 4 ideally used for the device according to the invention, which firstly and substantially comprises a hollow cylindrical outer part 5, and a conical dispensing part 6 and an inner part 7 arranged in the outer part 5, In this case the inner part 7 almost completely seals off the open side of the hollow cylindrical outer part 5 . On the front face of the inner part 7 , grooves 8 can be considered to accommodate the heads of screws 9 attaching the outer part 5 to the inner part 7 .

Abstract

The invention relates to a method and a device for thermally activating tubular packaging sheaths (1) made of a cardboard / plastic composite material, in particular for packaging for fluid foodstuffs, wherein a hot gas is applied to the tubular packaging sheath (1) using a heating device, in order to produce the base or the head of the packaging. According to the method and the device, in order to achieve a simultaneous heating for activating the contact surfaces in a constructively simple production, the energy required for the activation process is used as completely as possible for heating the surfaces to be activated, the heating device is brought into operative contact with the surfaces to be activated, and the heating device for activation is moved into the inside of the tubular packaging sheath (1). In addition, the heating device comprises a nozzle element (4) having at least one outlet opening and the outer shape of the nozzle element corresponds to the inner shape of the end to be activated of the tubular packaging sheath (1).

Description

technical field [0001] The invention relates to a method for thermal activation of tubular packaging sleeves made of cardboard / plastic composite material, in particular for packaging of liquid food products, wherein hot gas is applied to the tubular packaging by means of a heating device Sleeve to make the base or head of the package, wherein the heating means is placed in effective contact with the surface to be activated by moving the heating means inside the tubular packaging sleeve for activation contact, and wherein the tubular packaging sleeve is disposed on the mandrel of the mandrel wheel. Furthermore, the invention relates to a device for thermal activation of tubular packaging sleeves made of cardboard / plastic composite material, in particular for packaging liquid food products, wherein hot gas is applied to the Tubular packaging sleeve to manufacture the base or head of said packaging, and wherein said heating device has at least one nozzle element with a discharge...
