Abstract
The present invention relates to a nicotine inhaling device and a method for making the same. Such device allows a user to ingest nicotine vapours orally and it is primarily intended to be used as a smoking cessation aid.
Claims6
A nicotine inhaling device with an extended shelf life, containing a measured amount of nicotine in a gas atmosphere which can selectively be made accessible to a user by oral ingestion of vapors, comprising:
- a) a nicotine reservoir for holding and dispersing a measured amount of nicotine;
- b) a substantially cylindrical nicotine impermeable barrier formed as part of the nicotine reservoir, having a first open end and a second open end and an internal surface and an external surface, said nicotine barrier layer consisting essentially of a polyethylene terephthalate (PET) which has been subjected to surface modification with Inorganic Oxides or Amorphous Carbon on both the internal and external surfaces;
- and
- c) a first seal and a second seal, the first seal being heat sealed to the first open end and the second seal being heat sealed to the second open end to form a continuous nicotine impermeable barrier so that the nicotine is prevented from migrating outside the reservoir.

- b) a substantially cylindrical nicotine impermeable barrier formed as part of the nicotine reservoir, having a first open end and a second open end and an internal surface and an external surface, said nicotine barrier layer consisting of a polyethylene terephthalate (PET) polymer which has been subjected to surface modification with Inorganic Oxides or Amorphous Carbon on both the internal and external surfaces;
- and
- c) a first aluminum seal and a second aluminum seal, the first aluminum seal being heat sealed to the first open end and the second aluminum seal being heat sealed to the second open end to form a continuous nicotine impermeable barrier so that the nicotine is prevented from migrating outside the reservoir.
