Problems solved by technology

[0017] In fact, for conventional multilayer tape structures, if T2 is greater than T1, the inner layers, once melted, will mix and will destroy the tape at the overlapping area, thus creating a weak point that results, for example, in poor seal barrier properties, which Optimal storage of cosmetics to be poured into the inside of the tube is no longer guaranteed

[0142] During the formation of the shell by winding the tape 1, as image 3 As shown, the first side boundary portion 2 overlaps the second side boundary portion 2'.

[0143] Figure 4 A series of layers in the overlapping region 3 is shown.

[0144] For greater clarity, the layer at the second side boundary portion 2' has a corresponding numbering to the layer at the first side boundary portion 2, since they are the same layer, but are numbered with an additional "prime" to distinguish them.

[0145] In order from the outside of the envelope towards the inside of the envelope, the layers are as follows:

[0146] -5: Protective layer on the first side boundary portion

[0147] -6: Printed layer on the first side boundary portion

[0148] -7: The sealable outer layer of the decorative film of the first side border portion

[0149] -8: Metallic luster coating of the decorative film on the first side boundary portion

[0150] -9: Metallic coated PET layer suppo...

Abstract

Device for manufacturing a tube skirt from a flexible strip, comprising a frame, an elongate cylindrical mandrel (30), a means used to advance and guide said strip to place it in the form of a sleevearound the mandrel (30), one of the side edges of said strip overlapping the other side edge in order to form an overlap region to be welded, an internal heating means (32) located inside the mandrel(30) for heating the internal face of the overlap region, and an internal cooling means (33) located inside the mandrel (30) for cooling the internal face of the overlap region and downstream from theinternal heating means (32). The device is characterised in that said cooling means (33) is arranged facing the overlap region and configured to be in direct contact with the overlap region zone.

Description

technical field [0001] The invention relates to a tool enabling the execution of a method for manufacturing a decorated flexible envelope. [0002] The tapes used in the context of the present invention traditionally consist of several layers of different materials that combine the various functions that the envelope must fulfill, namely flexibility, ability to retain the deformed shape of the envelope, diffusion barrier ( impermeability to vapor), printing media for decoration, etc. [0003] In fact, in the field of flexible tubes especially for cosmetic and toiletry products, appearance and decoration are very important. The tube must have a decorated outer surface, including metallic luster effects, hologram effects, sparkle effects and a broad color palette. [0004] Flexible pipe is made from a flat, multi-layer tape that is coiled to give a sleeve called a pipe shell. The winding is done so that the strips are given a cylindrical shape, the side borders of which are a...
