Definitions

  • the tobacco in products such a cigarettes, cigars and loose tobacco for pipe smoking or roll-your-own cigarettes is prone to drying out both during the pre-use storage period and particularly after the product packaging has been opened. This is undesirable, since tobacco becomes less palatable as it dries.
  • the permeable layer may comprise a semi-permeable one-way membrane that transmits evaporated liquid from the gel body but substantially blocks the passage of water vapour or liquid to the gel body.
  • This arrangement allows the required moisture release from the gel to the tobacco, but prevents the gel from absorbing moisture back from the tobacco. This is beneficial in a situation where the humidifier has been left in a package of tobacco for a long time and has given up all its liquid; it is then undesirable for the gel to take moisture away from the tobacco. Also, it prevents brown discoloration of the gel which can arise from absorption of moisture from tobacco, and stops the take-up of scents and flavours from the tobacco which would reduce the product quality.
  • the humidifier may further comprise a removable outer layer covering the permeable layer that is substantially impermeable to the passage of the evaporated liquid, the outer layer intended to be removed before use of the humidifier.
  • a "water-proof outer layer of this type which stops the gel from giving up its liquid, allows humidifiers to be supplied independently from packaged tobacco products so that a smoker can utilise one as and when he finds his tobacco has become dry.
  • the humidifier may further comprise an outer layer covering the permeable layer that is substantially impermeable to the passage of the evaporated liquid, the outer layer having in it one or more apertures covered by one or more sealing members, the sealing member(s) being removable from the outer layer to open the aperture(s) before use of the humidifier.
  • this embodiment gives the option of re-sealing the apertures once enough moisture has been released, allowing the remainder to be released at a later time. It also offers further scope for tailoring the rate of evaporation, by the provision of larger, smaller, fewer or more apertures.
  • These different moisture release rates can be provided according to the present invention by engineering the gel body.
  • Various properties and characteristics can be modified to tailor the evaporation rate. These include selection of the material comprising the gel particle network, the density of the gel network (for example, how tight or loose die network is), the ratio of liquid to gel material, the size and shape of the gel body, and the type of liquid used.
  • gel materials are pectins, which are similarly biocompatible.
  • Additives of this type may similarly be used with non-water liquids.
  • a further example of a suitable permeable layer is a material comprising a thermo- mechanically expanded polymer membrane having microscopic pores that render the material permeable to the evaporating vapour from the gel body.
  • This type of membrane can be used alone, or laminated with a fabric. In the latter form, it is commonly used to make waterproof clothing, under brand names such as GORE-TEX (RTM).
  • the microscopic pores (micropores) are of a size to let water vapour through, but to block the passage of liquid water.
  • Suitable polymers from which these membranes can be made include polytetrafluoroethylene, polybutylene terephthalate and polyethylene oxide.
  • Humidifiers according to the present invention may include additional features in various combinations with the features described.
  • the humidifier may further comprise a sealed compartment containing a supercoolable salt hydrate solution that can be activated to crystallise and release heat to the gel body, thereby increasing the rate of moisture release by evaporation.
  • Humidifiers comprising such heat-releasing elements are described in our co-pending application GB 0710776.6 "Heatable humidifying device for use with tobacco products", filed in the United Kingdom on 5th June 2007.

Abstract

L'invention concerne un humidificateur utilisé avec des produits à base de tabac comprenant un corps gélifié constitué d'un réseau poreux continu de particules qui supportent un volume de liquide d'humidification, ledit corps gélifié étant configuré pour libérer le liquide par évaporation à une vitesse prédéterminée, et une couche perméable renfermant le corps gélifié qui peut être traversée par le liquide évaporé. Le corps gélifié peut être conçu pour obtenir un taux d'évaporation et donc une vitesse de distribution d'humidité appropriés pour répondre au besoin d'hydratation d'un tabac particulier. Les gels utilisés pris en exemple comprennent les alginates et les pectines. Des substances de modification supplémentaires, telles des sels, peuvent également être utilisées pour adapter ensuite le taux d'évaporation.
