Definitions

  • the invention relates to a tipping paper with thermally expandable particles.
  • the invention relates in particular to tipping paper for cigarettes and heat-not-burn consumer articles or, in general, to tipping papers for aerosol-generating consumer articles.
  • the tipping paper is the part of the aerosol-generating consumer product that is touched by the person's lips when smoking a filter cigarette or heating the heat-not-burn consumer product.
  • the tipping paper surrounds the filter portion and typically extends slightly into the longitudinal area of the tobacco rod or aerosol-generating substrate, where it envelops the cigarette paper or the wrapping material of the aerosol-generating substrate.
  • the tipping paper forms the outermost wrapping material of an aerosol-generating consumer product and, unlike cigarette paper, is not burned during use.
  • the tipping paper is usually actually paper, but it can also be a film or a composite material made up of several layers of different materials.
  • the mouthpiece tipping paper often has a print. This print can, for example, resemble cork. However, mouthpiece tipping papers are also used that are white in the area touched by the lips.
  • the WO2019110768A1 discloses a heat-expandable centering element in the form of an additional element located on the outside of the casing material.
  • the centering element is, for example, a bimetallic element.
  • the WO2017115196A1 relates to a smoking article that itself contains a flammable heat source. To extinguish the burning heat source, it is moved into a tube.
  • the tube may have a heat-responsive material on the inside to assist in extinguishing the burning heat source.
  • the object underlying the invention is to provide a structured tipping paper and an improved method for producing a structured tipping paper.

  • the tipping paper can be provided with foil elements, particularly metallic foil elements, in the hotfoil machine. These are often thin ribbons or logos.
  • Hot stamping is performed using conventional methods, whereby the foil element is applied to the tipping paper using pressure and heat from a transfer element.
  • the areas of the tipping paper that will be coated with the foil elements are heated more intensely during the hot stamping process, causing the particles beneath a foil element to expand.
  • a machine for coating the tipping paper with ink can be arranged upstream of the machine for coating the tipping paper with varnish, or the machine for coating the tipping paper with varnish can also have means for coating with another printing ink.

  • the belt which is moved through the machine for coating the tipping paper with printing ink or varnish, is composed of several tipping papers transverse to the direction of movement, whereby the direction of the tipping paper which is transverse to the direction of movement, i.e. along the width of the belt, is later arranged in the longitudinal direction of the consumer article.
  • the machine for printing or coating the tipping paper with printing ink or varnish has a cutting device which cuts the strip in the longitudinal direction after it has been provided with the printing ink or varnish layer, so that at least two narrower strips of tipping paper coated with printing ink or varnish are obtained, which are each wound up into a reel.
  • these reels are fed with narrower ribbons to the machine for hot stamping the tipping paper.
  • thermally expandable particles are expandable microspheres, which expand into hollow spheres with a larger volume when exposed to heat.
  • the expandable microspheres can contain a gas or a liquid, which expands under the influence of heat, or which evaporates with an increase in volume. The deformation is irreversible and persists after cooling.
  • the thermally expandable particles are preferably in the form of thermoplastic polymer particles or gel particles.
  • the expansion of the particles is preferably achieved through contact technology. This involves transferring a raised structure from a hot surface to the die lining as a raised structure. This contrasts with conventional embossing processes, in which the raised structure of a surface is transferred to the die lining as depressions.
  • the expansion of the particles can also be carried out contactless, for example by heating the area to be expanded with a laser beam.
  • the expandable particles preferably have an expansion temperature of 100°C to 250°C.
  • the expandable particles preferably have an average particle size of 1 ⁇ m to 50 ⁇ m in the unexpanded state. Upon expansion, their diameter preferably increases five to fifteen times.

  • the laser can be moved line by line across the surface of the tipping paper, with the laser beam only hitting the tipping paper or the laser being switched on on the later raised areas.
  • the laser beam can also be moved across the surface of the tipping paper according to a predefined path along two coordinates. If the laser beam is applied to a continuously moving path of the tipping paper, moving the laser beam transversely to the transport direction of the tipping paper may be sufficient.
  • the path of the laser beam and/or the on-off pattern of the laser beam can be individually programmed, allowing differently shaped elevations to be created on the tipping paper.
  • the elevations of tipping papers arranged consecutively in the web direction can differ from one another in their shape or position, or, if a code is present, in their meaning.
  • the elevations of tipping papers arranged consecutively across the web direction can differ from one another in their shape or position, or, if a code is present, in their meaning.
  • the tipping paper is coated with a varnish or a water-based printing ink only in certain areas, whereby the thermally expandable particles are contained in the varnish or printing ink.
  • the expandable particles are only in certain areas on the tipping paper, so that the tipping paper has at least one area with expandable particles and at least one area without expandable particles. At least one of the areas can be in the form of a symbol, code or pattern.
  • the varnish or water-based printing can be transparent or can match the colour of the background or the area of the tipping paper not covered with this varnish or water-based printing.
  • the area containing expandable particles cannot be visually distinguished from the area without expandable particles. Only when heated do the areas become tactile and therefore possibly also visually distinguishable, since after heating the areas containing expandable particles stand out from the other areas in relief.
  • the heating can be carried out on the web material of the tipping paper, on the cigarette machine or on a finished aerosol-generating consumer article before, during or after use.
  • This design variant makes it possible to create a security feature that is not initially visible, but can be made detectable by heating in order to detect counterfeit products that do not have this security feature.
