Definitions

  • the present invention relates to a smokeless cigarette having a nicotine and / or aroma matrix.
  • a matrix is intended to contain nicotine or one or more nicotine-containing compounds and / or flavorings and to retain them during the active phase, i. while using a smoke-free cigarette again.
  • Smoke-free cigarettes are known from the prior art in various embodiments.
  • a smoke-free cigarette that has a heat pipe that is heated by the flame of a lighter. Due to its high heat capacity, the heat pipe releases heat over a sufficiently long period of time so that the stimulant contained in a reservoir can evaporate.
  • a smoke-free cigarette which has a nicotine depot and which is distinguished by the fact that heating the air stream passed through the nicotine depot is not required to release the nicotine is.
  • the nicotine reservoir contains a carrier that is already in its gas phase at ambient temperature.
  • the WO 2007/054167 A1 relates to a smokeless cigarette having a heater running with a current-carrying heating wire for heating a reservoir from which nicotine is released.
  • WO 2007/054167 A1 discloses, for example, that nicotine is present in a smokeless cigarette as a nicotine salt, which pyrolyzes when exposed to heat and release nicotine as a free alkaloid.
  • DE 690 12 823 T2 discloses a smokeless cigarette containing a nicotine reservoir with nicotine-containing granules and excipients, preferably dextrose.
  • nicotine matrix includes any matrix or carrier that has nicotine or one or more nicotine-containing compounds.
  • aromaa matrix includes any matrix or carrier that has one or more flavorings, which also includes any flavorings.
  • the matrices are designed to thermally induce nicotine, release one or more nicotine-containing compounds or aromatics, for example by desorption.
  • the at least one matrix thus allows the controlled release of nicotine and / or flavorings, preferably by heating.
  • the correspondingly enriched air can then be drawn in by a user, if necessary through a filter of the cigarette.
  • Nicotine as an essential component of a smokeless cigarette must be safe in its storage and in its safety at risk and can be used.
  • the storability of the smokeless cigarette over a longer period means, among other things, that nicotine and / or aroma components are not released unintentionally.
  • a matrix according to the present invention will give no or substantially no nicotine and / or flavoring to the environment without thermal stimulation and will not or at least not substantially change upon prolonged storage in its composition and physicochemical properties.
  • the delivery of nicotine or of nicotine-containing compounds and / or flavorings does not begin until above approximately 45.degree. In a preferred embodiment, this release does not begin above about 50 ° C, in another embodiment above about 60 ° C. In further embodiments of the invention, the delivery may occur between about 45 ° C and about 60 ° C, preferably between about 50 ° C and about 55 ° C.
  • the at least one matrix is designed such that the desorption of nicotine and / or flavorings during storage is largely or completely prevented.
  • flavor and “flavor” are used interchangeably below and refer to any organoleptically effective, the matrix of the invention added substance.
  • nicotine stands for both the substance nicotine and any nicotine-containing substance.
  • the delivery of the substances can be understood in particular to be the desorption of previously adsorbed nicotine and / or previously absorbed flavorings, but also other suitable modes of release of previously associated nicotine and / or previously associated flavorings. Due to the well-defined, preferably provided discharge temperature range, and the fact that no or only a negligible part of the associated substances are delivered below the specified temperature range, it can be ensured that the composition remains stable over a longer period of time, provided the ambient and / or storage temperature the active temperature of the cigarette does not exceed.
  • a negligible portion is preferably understood to mean a proportion of less than 10% of the total amount of nicotine and / or of flavoring agents and preferably less than 5% of these substances.
  • the matrix is designed such that the storage stability of the contents of the cigarette is supported by nicotine and / or flavoring or flavors are released only during their active phase, preferably only with active pulling on the cigarette.
  • Matrices according to the invention can therefore be designed such that, for example, during a storage of the cigarette for several weeks or more, for example at a storage of 1 week, for example at room temperature (25 ° C.) and z. B. at 30% humidity less than 20 wt .-%, preferably less than 15 wt .-%, preferably less than 10 wt .-% and more preferably less than 5 wt .-% of their nicotine content and / or flavor content. In another embodiment, during this period, they give less than 2% by weight, more preferably less than 1% by weight. and more preferably less than 0.5% by weight of its nicotine content and / or flavor content.
  • the defined temperature range and the other optional properties of the matrix mentioned below allow a perfect interaction with a heat source, for example an internal, self-sufficient heating unit, which can serve as a heat source for the delivery of the absorbed or adsorbed substances.
  • a heat source for example an internal, self-sufficient heating unit, which can serve as a heat source for the delivery of the absorbed or adsorbed substances.
  • flavorings and / or nicotine can be delivered evenly over the duration of the active phase of the cigarette to the ambient air and thus be inhaled evenly by the consumer.
  • suitable nicotine and flavor matrices comprise one or more adsorbents, namely activated carbon powder, and glycol as matrix materials.
  • adsorbents namely activated carbon powder
  • glycol as matrix materials.
  • glycol also includes “glycolene”.
  • adsorbent materials in addition to the activated carbon powder used according to the invention, in principle other preferably pulverized adsorbent materials can also be used, such as, for example, silica gel, bentonite and / or alumina powder.
  • Suitable glycols include diols such as glycol, triols such as glycerine, oligools, and polyols whose groups may be vicinal or non-vicinal and which have suitable viscosities for the above-outlined use.
  • various comparable viscous fluids with polar properties can be used.
  • the glycol and / or powder components can be combined freely in terms of their material and relative composition.
  • Adsorbent and glycol levels in one embodiment are approximately or exactly 1: 1 in the matrix.
  • the matrix contains about 50% by weight activated carbon powder and about 50% by weight glycols.
  • the matrix contains between about 30% by weight and about 70% by weight of activated carbon powder and between about 30% by weight and about 70% by weight of glycols.
  • the matrix contains between about 40 weight percent and about 60 weight percent activated carbon powder and between about 40 weight percent and about 60 weight percent glycol, and in a preferred embodiment, the matrix contains between about 45 weight percent 55% by weight and about 55% by weight of activated carbon powder and between about 45% by weight and about 55% by weight of glycol.
  • the nicotine matrix and / or the flavor matrix can thus contain at least one adorbent, such as activated carbon, at least one glycol (and / or glycolene) and possibly also admixtures.
  • adsorbent powders in particular adsorbent powders and mixtures thereof.
  • Glycols as used herein also include mixtures of several glycols or other suitable substances in admixture with glycols or with each other.
  • compositions can deliver the associated substances particularly uniformly in the above desired temperature ranges.
  • the matrix may be inhomogeneous.
  • individual matrix sections may have different mixing ratios of adsorbent powder and glycol, with the composition of all sections preferably being within the limits specified above.
  • the individual sections may also differ in their total loading of nicotine and flavorings, as well as in the relative composition of nicotine and flavorings, or in the relative composition of different flavorings. This can be a mutual influence or even a negative cross-behavior between nicotine and flavor release can be reduced or even prevented.
  • a matrix portion or a total matrix may contain only nicotine and / or flavoring only.
  • the at least one aroma matrix and the at least one nicotine matrix are present separately, for example next to one another, in the cigarette. They are preferably introduced separately into the cigarette.
  • the invention includes a smokeless cigarette having at least one nicotine and / or aroma matrix according to claim 1.
  • a smoke-free cigarette may also have a plurality of such matrices.
  • the matrix is applied to a carrier and then placed in the smoke-free cigarette, for example on its heat-generating unit. This facilitates the production of the smokeless cigarette.
  • Suitable carriers are open-pore, organic structures, as well as open-cell polymer foams, for example polyolefins, polyethers, polyesters, polyamides, polycarbonates, and the like, as well as similar carrier media such as silica gel, aluminum oxide, zeolites, carbon, metals, etc.
  • a nicotine and / or aroma matrix or the individual matrix application can be applied directly to a heat source, for example on a heat pad, or placed on a heat pad.
  • a heat source for example on a heat pad, or placed on a heat pad.
  • a matrix placed on a carrier can, in one embodiment, have an improved assembly behavior and lead to a better heat distribution.
  • a near-core arrangement of the matrices whereby the remaining space of the cigarette can be filled with other materials, such as tobacco, habitual, for example, haptic properties of conventional cigarettes can be preserved in one embodiment.
  • a carrier for example, open-pored organic structures are used.

  • the crystallization medium is, for example, a salt hydrate, for example sodium acetate trihydrate into consideration.
  • the crystallization medium may be present as a supersaturated solution which crystallizes upon activation, thereby releasing heat.
  • This heat serves to promote or even initiate the desorption of nicotine and / or flavorings and / or flavors from a substrate.
  • the present embodiment thus relates to a smoke-free cigarette with an internal self-sufficient, i. no energy or heat input from the outside requiring heat unit and / or with a matrix containing nicotine and / or flavorings and / or flavorings.
  • the tobacco or said matrix may partially or completely surround the heating unit.
  • a reverse arrangement heat unit surrounding the tobacco or the matrix partially or completely is conceivable.
  • the smoke-free cigarette further preferably has at least one filter. This can be arranged for example in the mouthpiece, form the mouthpiece or include the mouthpiece.
  • the filter may consist of or comprise one or more open-pore polymer structures and / or open-pore synthetic structures and / or microfiber synthetic structures and / or perlon textile structures. These filter materials have the advantage that they do not or not substantially, preferably less than 5%, less than 2% and particularly preferably less than 1% or less than 0.5% influence the composition of the gas flow of the smoke-free cigarette during the flow through the filter ,

  • the nicotine-containing parts of the matrix regulate the nicotine concentration in the gas stream during the active phase of the cigarette when it is pulled on the cigarette. Regardless, during the active phase of the cigarette, the flavor-containing portions of the matrix regulate the aroma concentration in the gas stream as it is drawn to the cigarette.
  • aroma matrix or aroma matrices and nicotine matrix or nicotine matrices are introduced separately into the smoke-free cigarette.
  • the nicotine and the aroma matrix are not present separately but mixed.
  • a variation of this embodiment comprises the above-mentioned characteristics, wherein the matrix is first applied to a carrier and then placed in the cigarette, for example on the heat pad.
  • the carrier used is, for example, an open-pore organic structure.
  • Such a smoke-free cigarette is by the use of matrix elements consisting of activated carbon powder and glycols, wherein the mixing ratio is about 1: 1, with desorption between 50 ° C and 55 ° C, over a longer period safely storable.
  • the composition of the cigarette does not change or only imperceptibly.
  • this matrix releases less than 5% by weight of its nicotine and flavor content.
  • the environment is lined with tobacco or substances with similar or the same haptic properties, so that the usual feel of conventional cigarettes is not waived must become.
  • the appearance of the cigarette can thus be matched to the appearance of conventional cigarettes.
  • the use of the nicotine and aroma matrix in the present example thus achieves desorption-free storage of the cigarette and control of the release of nicotine by heating.
  • the matrix is divided into two groups, namely a flavor matrix and a nicotine matrix.
