This application claims priority from U.S. provisional application number 60/929,010, j filed on June 8, 2007, the entire content of which is incorporated herein by reference.
BACKGROUND
Flavorants are frequently added to tobacco products, including smoking articles or smokeless, oral tobacco products, to achieve desirable organoleptic sensations. Typically, the ) flavors are added to the tobacco material or filter component.
SUMMARY
As described herein, smoking articles include a controlled flavor release product that provides prolonged and varied organoleptic sensation. 5 Provided is a controlled flavor release product including at least a first time-release flavorant and a second time-release flavorant. Additional time-release flavorants may also be included.
Preferably, the first time-release flavorant and the second time-release flavorant contain different flavorants, but they may contain the same flavorants. In an embodiment, the first time- D release flavorant and the second time-release flavorant contain the same flavorant. Also preferably, the first time-release flavorant and the second time-release flavorant are released at different times during smoking to provide continuous enjoyment and a variety of flavors. Also preferably, the time release of the second time-released flavorant overlaps release of the first time-released flavorant. 5 In a preferred embodiment, the first time-release flavorant and the second time-release flavorant are incorporated into controlled release microcapsules. The microcapsules may be embedded in a format to create a controlled flavor release product. Each microcapsule can contain the first time-release flavorant, the second time-release flavorant or both.
In another embodiment, the microcapsules form the controlled flavor release product o that can be used in a smoking article. Preferably, the controlled flavor release product includes at least a first time-release flavorant and a second time-release flavorant.
Suitable microcapsules for controlled release of flavorants are those developed by
Salvona LLC of Dayton, New Jersey, (e.g. MultiSal™ and NanoSal™).
MultiSal™ is a free flowing powder matrix with high concentrations of functional 5 ingredients encapsulated in nanospheres. NanoSal™ is a liquid formula encapsulated in solid, hydrophobic nanospheres. Each microcapsule can incorporate different oil based flavors for controlled delivery over time. The microcapsules provide enhanced bioadhesive properties such that the flavorants bind to mucous in the mouth cavity to prolong flavor enjoyment. The microcapsules may also be designed to target specific areas of the mouth.
In a preferred embodiment, the controlled flavor release product has controlled diffusion mechanisms. The first time-release flavorant and the second time-release flavorant may be released by the same or different mechanisms at the same or different times. Additional time- release flavorants may be used, and may be triggered by different methods at different times.
In one embodiment, the first time-release flavorant and the second time-release flavorant are released by exposure to moisture from the lips or mouth. In another embodiment, heat from igniting the smoking article or from the user's mouth may cause the release of the first time-release flavorant and the second time-release flavorant. In yet another embodiment, the first time-release flavorant and the second time-release flavorant are released by a change in pH. The change in pH may occur when the controlled flavor release product is placed in an environment such as a human's mouth. Alternatively, a substance may be added to a microcapsule that changes the pH and causes the release of another microcapsule.
Preferably, the first time-release flavorant and the second time-release flavorant are embedded in a format to create a controlled flavor release product. In a preferred embodiment, the controlled flavor release product is in the form of a lip balm type formulation. The lip balm type formulation may be made of a wax with the first time-release flavorant and the second time-release flavorant embedded therein. In another embodiment, the controlled flavor release product is in the form of a film having a first time-release flavorant and a second time-release flavorant embedded therein. The films can be formed by conventional means known in the art, and may be dissolvable and/or disintegrable. Preferably the film is adhered to the downstream end of the smoking article.
In an embodiment, the first time-release flavorant may include a different flavorant than the second time-release flavorant so that the user is provided with at least two flavors during the smoking experience. Also, since the first time-release flavorant and the second time-release flavorant are released at separate times, the organoleptic sensations are prolonged thereby providing the user with more flavor over a longer period of time.
Suitable flavorants for use in the controlled flavor release product include, without limitation, mint, such as peppermint and spearmint, vanillin, chocolate, licorice, citrus and other fruit flavors, spice flavors, such as cinnamon, methyl salicylate, linalool, bergamot oil, geranium oil, lemon oil, ginger oil, tobacco flavors and other agents commonly used to impart flavor and aroma to tobacco products.
Other suitable flavors and aromas may include flavor compounds selected from the group consisting of an acid, an alcohol, an ester, an aldehyde, a ketone, a pyrazine, combinations or blends thereof and the like. Suitable flavor compounds may be selected, for example, from the group consisting of phenylacetic acid, solanone, megastigmatrienone, 2- heptanone, benzylalcohol, cis-3-hexenyl acetate, valeric acid, valeric aldehyde, ester, terpene, sesquiterpene, nootkatone, maltol, combinations thereof and the like. The first and second flavorants may contain a cooling agent.
Additives such as chemesthesis agents may also be included in the controlled release flavor product. Suitable chemesthesis agents include, without limitation, capsaicin, tannins, mustard oil, wintergreen oil, cinnamon oil, allicin, quinine, citric acid, and salt.
In one embodiment, complimentary flavors may be chosen for the first time-release flavorant and the second time release flavorant to provide a combined flavor. For instance, a cherry vanilla flavor may be provided by choosing a cherry flavorant for the first time-release flavorant and a vanilla flavorant for the second time-release flavorant. In an embodiment, the release of the first time-release flavorant and the second time-release flavorant can overlap so that the complimentary flavorants can be enjoyed together.
The term "smoking article" includes cigarettes, pipes, cigars, and cigarillos. Non- traditional cigarettes such as cigarettes using electrical smoking systems are also included in the definition of smoking articles or cigarettes generally.
A traditional cigarette typically contains two sections, a tobacco-containing portion sometimes referred to as the tobacco rod, and a filter portion which may be referred to as a filtration zone. Tipping paper typically surrounds the filter, which forms the mouth end of the cigarette. The tipping paper overlaps with the tobacco rod in order to hold the filter and tobacco rod together. The tobacco rod includes a paper wrapper in which the tobacco is wrapped and an adhesive holding the seams of the paper wrapper together. The tobacco rod has a first end which is integrally attached to the filter and a second end which is lit or heated for smoking the tobacco. When the tobacco rod is lit or heated for smoking, the smoke travels from the lit end downstream to the filter end of the tobacco rod and further downstream through the filter.
The "upstream" and "downstream" relative positions between filter segments and other features are described in relation to the direction of mainstream smoke as it is drawn from a tobacco rod and through a multi-component filter during a puff.
In a preferred embodiment, the smoking article is a cigarette. The cigarette may contain tobacco material, a filter, and a controlled flavor release product. In an embodiment, the cigarette may also contain at least one sorbent.
