July 25, 2014



By a News Reporter-Staff News Editor at Health & Medicine Week -- According to news reporting originating from Washington, D.C., by NewsRx journalists, a patent application by the inventors Nicholls, Jane (London, GB); Awty, Edward (London, GB); Spencer, Alfred Vincent (London, GB); Nandra, Charanjit (London, GB); Frobisher, Paul (Clevedon, GB); Newnham, Michael (Clevedon, GB), filed on May 11, 2012, was made available online on July 10, 2014 (see also British American Tobacco (investments) Limited).

The assignee for this patent application is British American Tobacco (investments) Limited.

Reporters obtained the following quote from the background information supplied by the inventors: "As used herein, the term 'smoking article' includes smokeable products such as cigarettes, cigars and cigarillos whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes and also heat-not-burn products (i.e. products in which flavour is generated from a smoking material by the application of heat without causing combustion of the material). Typically, smoking articles are provided with filters for removing constituents from the smoke.

"It is known to provide additive release components containing additives such as flavourants inside smoking articles. By applying force to the outside of the smoking article, the smoker may break the additive release component and release the flavourant. Thus, a smoker wishing to add flavour to the smoke may do so by simply squeezing the smoking article."

In addition to obtaining background information on this patent application, NewsRx editors also obtained the inventors' summary information for this patent application: "According to a first aspect, an additive release component for use in a smoking article having a filter is provided, the component comprising a rupturable shell containing an additive, wherein the component is configured to eject the additive into the filter of the smoking article in a predetermined direction in response to compression of the component.

"In some embodiments, the shell has a three-dimensional shape which causes it to rupture in a predictable and consistent way in response to compression.

"In some embodiments, the three-dimensional shape of the shell concentrates the compressive force applied to the additive release component on a limited area of the shell so that the shell ruptures in a predetermined region.

"In some embodiments, the shell has a three-dimensional shape which forces the contained additive in a pre-determined direction prior to and/or upon rupture of the shell.

"In some embodiments, the shell has a three-dimensional shape which is not symmetrical about a plane perpendicular to the longitudinal axis of the smoking article.

"In some embodiments, the additive release component is not spherical.

"In some embodiments, the additive release component is ovoid, conical, hemispherical, trapezoidal, or pyramidal.

"In some embodiments, the shell does not include an area or line of weakness formed by creating a recess, hole or groove in the shell.

"According to a second aspect, a filter for a smoking article comprising an additive release component in accordance with the first aspect is provided.

"In some embodiments, the filter further comprises a secondary element. This secondary element may be a support structure within which the additive release component is positioned, and/or the secondary element may comprise a wicking element.

"In some embodiments, the additive release component is aligned with a longitudinal axis of the filter.

"In some embodiments, the additive is released from the component in a direction parallel to a longitudinal axis of the filter.

"According to a third aspect, a smoking article comprising an additive release component in accordance with the first aspect, or a filter in accordance with the second aspect, is provided.

BRIEF DESCRIPTION OF THE DRAWINGS

"An embodiment will be described, by way of example only, with reference to the accompanying drawings (not to scale), in which:

"FIG. 1 shows a smoking article filter comprising an additive release component in accordance with a first embodiment;

"FIGS. 2A and 2B show an additive release component support structure with and without an additive release component in accordance with a second embodiment;

"FIG. 3 shows an exploded side elevation view of a smoking article comprising an additive release component according to the second embodiment within a support structure."
