Definitions

  • the present invention relates to a smoke-free cigarette.
  • Smoke-free cigarettes are known in many different embodiments. They generally have a nicotine-containing reservoir from which the nicotine is released by desorption when exposed to heat and then supplied to the user with a draft through the smoke-free cigarette. Furthermore, flavoring agents can be provided which are desorbed from a matrix when the cigarette is used and then also supplied to the user with the draft.
  • the present invention has the object of developing a smoke-free cigarette to the effect that the unwanted volatilization of nicotine and / or flavorants is prevented, thus giving the smokeless cigarette a particularly good shelf life over a longer period.
  • the smoke-free cigarette comprises a multi-layered outer shell, the outer layer of which has the optical properties of a conventional cigarette, of which another layer is a desorption barrier designed to inhibit the desorption of nicotine and / or flavors, or at least substantially limited, and of which another layer is a stabilizing layer adapted to give the cigarette the mechanical stability required for use.
  • the present invention thus relates to a smokeless cigarette with a Mehrla- Ex Tohülle whose layers fulfill different tasks.
  • the multi-layer outer casing is preferably completely or substantially desorption-tight, that is, nicotine and / or flavors remain in the space surrounding the outer casing, even if the smoke-free cigarette is stored for a long time.
  • the outer shell may have the three layers mentioned or consist of these.
  • the invention further relates to a smoke-free cigarette with one or more layers having outer shell, of which the outer layer consists of paper or paper, of which another layer consists of metal or metal and of which another layer consists of a plastic material or a plastic material.
  • the paper layer may be the layer having the optical properties of a conventional cigarette, the metal layer may be the layer preventing or at least substantially hindering desorption, and the plastic layer may be the layer act, which gives the smoke-free cigarette the required mechanical stability.
  • the outer layer of paper serves to configure the haptic, optical and tactile properties of a conventional cigarette.
  • the directly or indirectly inwardly following metal layer, preferably aluminum layer forms the desorption barrier for nicotine and flavorings. Preferably, it also serves to regulate the heat during the active phase, that is, during the use phase of the smokeless cigarette.
  • the further and relative to the metal layer inside layer may consist of a plastic layer. On the one hand, it provides the necessary overall stability and, preferably, tension control and aroma resistance.
  • the overall arrangement that is, the multi-layer outer shell can be made single-layered or as a composite material.
  • the desorption barrier is arranged between the outer layer and the stabilization layer, or that the layer consisting of metal or metal is disposed between the outermost layer and the layer consisting of plastic material or having a plastic material.
  • the desorption barrier forms a "middle layer" which is located between the outer layer and the inner layer.
  • the layers of the multilayer outer shell can adjoin one another directly.
  • the invention also includes that one or more further intermediate layers are arranged between the individual layers.
  • the outer shell consists only of these three layers.
  • the metal is preferably aluminum.
  • the desorption barrier is thus preferably formed by an aluminum layer or by a layer which comprises at least aluminum.
  • the desorption barrier may be in the form of a film, preferably in the form of a metal foil and particularly preferably in the form of an aluminum foil.
  • At least one layer, preferably several or all layers of the outer shell in the form of a cigarette is cylindrical.
  • the layers of the outer shell all extend over the same length or over different lengths of the cigarette.
  • the smoke-free cigarette has a mouthpiece, and that the desorption barrier and / or the stabilization layer extend as far as the mouthpiece and the outer layer also around the mouthpiece.
  • the outer layer that surrounds the mouthpiece has the same color as a conventional cigarette in the region of the filter.
  • the mouthpiece is arranged so that the user picks up the nicotine and / or the flavorings with a warmed draft of air through the mouthpiece.
  • the mouthpiece to be adjoined by a space in which a nicotine reservoir and / or a reservoir for flavoring substances and / or a self-sufficient heating unit are arranged.
  • the thickness of the layers of the outer shell is identical.
  • the invention also includes that one layer has a smaller thickness than the other two layers or that one layer has a greater thickness than the other two layers.
  • the desorption barrier which may be embodied as a foil, has a smaller thickness than at least one or else both of the other two layers.
  • the stabilization layer has a greater thickness than at least one or both of the other layers.
  • the outer shell surrounds a space in which a self-sufficient heat generating unit and / or nicotine and / or flavorings are arranged.
  • the nicotine or the flavorings can be arranged on a matrix, preferably on tobacco or else on another suitable matrix material. They are desorbed there when the cigarette is used.
  • a heat source is used for desorption. This can be carried out, for example, in the form of a self-sufficient heating unit, that is, as a heat source that does not require external energy supply.
  • the self-sufficient heating unit comprises a medium which can be converted into the crystalline state at ambient temperature.
  • a medium which can be converted into the crystalline state at ambient temperature.
  • sodium acetate trihydrate, sodium sulfate or sodium sulfate compounds, magnesium nitrate hexahydrate, etc. may be used.
  • This self-sufficient heating unit may be activated, that is, crystallized, by a user, by a triggering mechanism.
  • the multilayer outer shell has been manufactured in the form of a composite material or that the layers of the outer shell are produced individually and then possibly joined together by the use of connecting means.
  • the single figure shows a longitudinal section through a three-layer outer shell of a smokeless cigarette.
  • the outer shell consists of three layers of material.
  • the outer paper layer 1 serves to configure the haptic, optical and tactile properties of a conventional cigarette.
  • this paper layer 1 is adjoined by an aluminum layer 2, which forms the desorption barrier for nicotine and flavors / aromas present in the space surrounded by the outer shell.
  • the aluminum layer serves at the same time the heat regulation.
  • the aluminum layer 2 is followed by a plastic or plastic layer 3.
  • This consists of a plastic Läge and provides on the one hand for the necessary overall stability of the smokeless cigarette, for the Zugregultechnik and for the flavor resistance.
  • three layers may be provided to form the entire outer shell.
  • the invention also encompasses that between two or all of the illustrated layers there are intermediate layers which have certain functional properties, such as, for example, the adhesion of the layers to one another, etc.
  • the outer shell consists only of the three layers shown.
  • a major advantage of the arrangement shown is that a smokeless cigarette is provided which is storable over a longer period, since the desorption of nicotine or flavorants is largely hindered or completely prevented without having to give up the usual feel of conventional cigarettes.
  • the paper layer may form the outermost layer of the multilayer outer shell.
  • the invention also includes that a further layer, such as a coating or the like, is applied to this layer.
  • the inner layer that is, the plastic layer 3 may form the innermost layer of the multilayer outer shell.
  • a further layer such as an inner coating.
  • the three layers 1, 2, 3 of the outer shell are shown with identical or largely identical thickness.
  • the invention also includes the case that different thicknesses can be provided. For example, it may be sufficient.
  • the outer shell shown in longitudinal section in the figure has the form of a hollow-cylindrical body in the interior of which there is a matrix on which nicotine and flavorings are located. Furthermore, there is a self-sufficient heating unit in the interior, preferably in the form of a crystallizable medium.
  • This self-sufficient thermal unit can be activated, for example, by pressure on the outer shell shown from the outside by the user. This leads to crystallization and thus heat dissipation.
  • This heat release heats a draft of air which is drawn through the interior of the smokeless cigarette and possibly a mouthpiece. The heating further results in facilitating the desorption of nicotine and / or flavor from the aforementioned matrix.
  • the self-sufficient heating unit is designed so that it gives off heat over a typical useful life of a conventional cigarette.
  • the structure of the self-sufficient thermal unit and said matrix may be formed such that the matrix extends around the autonomous heating unit.
  • the invention also encompasses the fact that the self-sufficient heating unit extends around said matrix.
  • cigarette is to be interpreted broadly and includes, in addition to the actual cigarette, for example, cigars, cigarillos, etc.
