Definitions

  • the invention relates to a system for providing an inhalable aerosol and the components of such a system.
  • This system is particularly suitable as a smoking article for providing smoke aerosol for smokers.
  • a special film tobacco loaded with high amounts of glycerin is used as the aerosol-forming material.
  • Both of the above-mentioned smoking articles have in common that the combustion gases of the heating element are inhaled with the smoke aerosol, which leads to an increased absorption of carbon dioxide by the smoker.
  • the spatial separation of energy source and aerosol generator leads to a taste deficit on the first puffs due to the difficult heat transfer.
  • the entire smoking article which in contrast to conventional cigarettes maintains its length, must be disposed of after smoking. This leads to an increased incidence of complex residues and associated disposal problems.
  • a cigarette-shaped object with a filter and tobacco part is inserted into an electronically controlled smoking device at the tobacco end.
  • the tobacco-containing part is heated with the help of electrical heating elements at locations radially consecutive with the trains.
  • This principle requires a complex construction of the smoking device, which must be equipped with several heating elements and a complicated electronic control.
  • the handling of such a device is complex due to its size and design and differs significantly from that of a conventional cigarette.
  • the system according to the invention for providing an inhalable aerosol is particularly suitable as a smoking article, the functioning of which is based on the heating of an aerosol-forming material during the trains.
  • the portion of substrate is heated in the inhalation device during the trains by supplying electrical energy into the conductive casing, so that aerosol is formed, which can be absorbed by the smoker by drawing air through the air inlet opening of the casing via the aerosol outlet opening of the casing.
  • the use of the smoking article prevents the formation of sidestream smoke during train breaks.
  • the basic principle of the invention is therefore based on the closest possible spatial arrangement of the heat source and aerosol former. This is achieved in that the substrate portion itself has the heating resistor (or also several heating resistors), which is preferably designed as a conductive covering of the substrate portion and is heated by applying a voltage across the contacts in the inhalation device.
  • the system according to the invention has the advantage that, despite the simple construction, no combustion gases are inhaled and the residues remaining after use can be made environmentally compatible.
  • La is a perspective view of a portion of substrate according to the invention.
  • Fig. Lb shows a longitudinal section through the substrate portion
  • FIG. 1c shows a cross section through the substrate portion according to FIG. 1a
  • FIG. 2a shows a longitudinal section through another embodiment of a substrate portion according to the invention, which has an integrated mouthpiece
  • FIG. 2b is a perspective view of an embodiment of a substrate portion in which a number of axially spaced zones of electrical conductivity are provided
  • FIG. 2c shows a perspective view of an embodiment of a substrate portion in which a number of zones of electrical conductivity spaced apart in the circumferential direction are provided
  • FIG. 3 shows a schematic longitudinal section through an inhalation device according to the invention, into which the substrate portion according to FIG. 2a is inserted and which has a separate rates housing for control components and power supply,
  • FIG. 4a shows a schematic longitudinal section through another embodiment of an inhalation device according to FIG.
  • Invention which is constructed for the use of a separate mouthpiece and which has a separate housing for control components and power supply, with inserted substrate portion and inserted mouthpiece,
  • FIG. 4b is an illustration of the use of the system according to FIG. 4a by a smoker
  • FIG. 5 shows a schematic longitudinal section through a further embodiment of an inhalation device according to the invention, which is designed for the use of a separate mouthpiece and in which the power supply is located in the housing, with the substrate portion and the mouthpiece inserted.
  • FIGS. 1 a to 1 c A preferred embodiment of a substrate portion 1 is shown in Figures la to lc.
  • the substrate portion 1 has a cylindrical shape, as can be seen from FIGS. 1 a to 1 c. It contains an aerosol-forming material 2 which is surrounded by an electrically conductive sheath 3 arranged radially (i.e. on the cylinder jacket).
  • the aerosol-forming material 2 can consist, for example, of cut leaf tobacco, cut tobacco ribs, reconstituted tobacco or a carrier material treated with aroma substances.
  • Leaf and rib cuts can also be used in expanded form, as is obtained, for example, by using the method described in the patents DE 29 03 300, DE 31 19 330 and DE 34 14 625.
  • Both organic materials such as, for example, can be used as carrier materials for flavorings Paper as well as inorganic such as silica gel are used. Any mixtures of the components mentioned can also be used.
  • material 2 contains about 3% to 30% volatile polyol, e.g. Glycerin or propylene glycol to increase aerosol formation.
  • volatile polyol e.g. Glycerin or propylene glycol
  • Another way of increasing aerosol formation is to use the aerosol-forming materials with a moisture which is significantly above the equilibrium moisture. For example, Tobacco, whose equilibrium moisture is around 10% to 12%, can be used with a moisture content of 20%. In this case, suitable packaging must be used to ensure that there is no loss of moisture until use.
  • the electrically conductive sheathing 3 can consist of paper or film tobacco provided with conductive additives (such as metals or graphite / carbon) or a plastic film likewise made conductive by additives.
  • conductive additives such as metals or graphite / carbon
  • a multi-layer wrapping can also be used, the inner layer consisting of paper or film tobacco and the outer layer made of one of the conductive materials mentioned.
  • Substrate portions 1 can be produced in a simple manner on a conventional cigarette rod making machine: First, an endless strand of tobacco or substitute material is formed in a format part; this is surrounded by the conductive wrapping material supplied in the direction of manufacture by a bobbin and glued to a seam. Then cut to the desired dimensions. Another possibility of production is the extrusion of a suitable aerodynamic sol-forming material through a round nozzle with subsequent wrapping and cutting of the extrudate.

  • the manufacture of such a composite is familiar to the person skilled in the art from the manufacture of filter cigarettes.
  • the substrate portion 1 can additionally have an increased electrical conductivity in zones 12 compared to the rest of the casing, which e.g. can be achieved by wrapping metal foil in zones 12 to improve electrical contact with the contacts in an inhaler (see below).

This can e.g. as in Figure 2b or as shown in Fig. 2c.
  • the wrapping of the substrate portion according to FIG. 2b has a number of annular zones 13 with a relatively high electrical conductivity, two adjacent zones 13 being separated by an insulating zone.
  • Each of the zones 13 forms a separate heating resistor which can be supplied with current individually in an inhalation device which is matched to the substrate portion via corresponding contacts in the inhalation device. The position of such contacts is indicated in Fig. 2b by arrows and the polarities "+" and "-".
  • the individual run Zones 13 do not extend over the entire circumference of the substrate portion, but each have an isolating interruption.
  • the zones 13 are electrically conductively combined in a zone which extends along the substrate portion and runs, for example, along the contact points "-" (or the contact points "+") according to FIG. 2b, so that in the inhalation device for this pole in the manner of a ground connection, only one contact must be present.
  • the envelope of the substrate portion has a number of electrically conductive zones 15 which are offset and insulated from one another in the circumferential direction.
  • the zones 15 serving as separate heating resistors extend over the length of the substrate portion.
