Description
ADDITIVE RELEASE COMPONENT
TECHNICAL FIELD
The present invention relates to additive release components for smoking articles.
BACKGROUND
As used herein, the term "smoking article" includes products for smoking such as cigars, cigars and cigarettes whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes and also products that are heated but they do not burn (that is, products whose taste is generated from a material for smoking by the application of heat without causing the combustion of the material) and other articles capable of generating aerosols derived from tobacco. Typically, smoking articles are provided with filters to remove smoke constituents.
The incorporation of additive release components containing additives such as flavorings into smoking articles is known. To the
applying force to the exterior of the smoking article, the smoker can break down the additive release component and release the flavor. Therefore, a smoker who wants to add flavor to the smoke can do so simply by squeezing the article to smoke.
BRIEF DESCRIPTION OF THE INVENTION

In some embodiments, the cover has a three-dimensional shape that causes it to break in a predictable and coherent manner in response to compression.
In some embodiments, the three-dimensional shape of the cover concentrates the compression force applied to the additive release component in a limited area of the cover so that the cover breaks in a predetermined region.
In some embodiments, the cover has a three-dimensional shape that forces the additive contained in a
default address before and / or in case of cover breakage.
In some embodiments, the cover has a three-dimensional shape that 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 cover does not include a weakening area or line formed by creating a recess, hole or slot in the cover.
According to a second aspect, a filter for a smoking article comprising an additive release component according to the first aspect is provided.
In some embodiments, the filter also comprises a secondary element. This secondary element can be a support structure within which the additive release component is placed, and / or the secondary element can comprise a breathable 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, there is provided a smoking article comprising an additive release component according to the first aspect, or a filter according to the second aspect.

DETAILED DESCRIPTION
An additive-releasing component is anything that is capable of retaining an additive and releasing it as and when desired. For example, the additive release component can be a capsule or other container and can comprise a sponge-like material, an adsorbent material, a gel material, or any other suitable material.
The additive can be released from the additive release component when compressive force is applied to the additive release component. In some embodiments, the additive is released in a predetermined direction.
When the additive is released from known additive release components, for example by breaking the component, the break can occur in any region of the surface of the component. Therefore, the additive can be released in any direction in the surrounding material of the smoking article, and is not directed in one direction
default The additive may additionally or alternatively be released generally with relatively little dispersion from the site where the additive release component is broken. On the other hand, the extension of this version of the additive is not predictable, being dependent in part on the force applied to the breakdown of the additive release component. This means that the amount of additive provided within the additive release components must be greater than necessarily that which is required in order to ensure deposition in the desired areas of the smoking article.
The additive release component according to the present invention comprises a breakable cover containing an additive. In some embodiments, this configuration can be described as comprising an outer cover and a central core, and the additive can be maintained in the central core. The core may simply be a cavity in which the additive is maintained. Alternatively, the core may comprise a material of type. sponge, an adsorbent material, or a gel material, in which the additive is maintained.
The additive can be released from the additive release component by any suitable means. In some modalities, the force exerted on the component
of additive release, for example by the user applying a compressive force, can induce the release of the additive. This may involve the breakdown of the additive release component. In addition, or alternatively, this may involve squeezing the additive from an additive release component comprising a porous or fluffy material.
The additive release component can be arranged such that upon activation of the additive release component, for example, by the application of a force such as a compressive force, the additive is ejected, squirted or driven by force of the additive release component, and therefore it is deposited further away from the additive release component and, optionally, over a larger area than is possible when the conventional additive release components are broken. From the direction of the predetermined release, the additive may be jet released or driven from the additive release component in a particular direction.
In contrast, conventional capsules can be broken in a random manner and, instead of being forcefully ejected, the additive can be passively filtered out of the rupture of the capsule, remaining in
the proximities of the capsule in a relatively localized and concentrated manner.
By configuring the additive release component to release the additive in a predetermined direction, the administration of the additive can be improved. The directional release of the additive means that the additive is released from the additive release component in a predetermined specific direction, which is predictable and consistent. The directional release may be a consequence of, and may be equivalent to, the directional breakage of the outer cover, which may result in the release of the additive in the direction facilitated by the break. Since certain three-dimensional shapes inherently break in a predictable pattern in response to the compressive force, the shape of the additive-releasing component used can determine the directional release of the additive from the additive-releasing component. For example, rupture of the outer shell of the component can provide a directional release of the additive in a predetermined direction.
In some embodiments, the outer cover has a three-dimensional shape that causes it to break in a predictable and consistent manner to compression. The rupture of the outer cover can, for example, be predictable
and consistent because the three-dimensional shape of the outer shell centers the compression force applied to the additive release component so that the force is greater at a predetermined region of the outer shell, causing it to break. This type of centering of the applied force is not possible with the outer cover having a spherical or other symmetrical shape, such as a tube having a circular, hexagonal or any other shape of regular and consistent cross section, so that in some embodiments, the outer cover does not have such a three-dimensional shape. Such an applied compression force approach may also not be possible when the outer cover has a three-dimensional shape that is symmetrical about a plane perpendicular to the longitudinal axis of the smoking article in which the additive release component is incorporated. Therefore, in some embodiments, the outer cover does not have this type of three-dimensional shape.
In some embodiments, it may be beneficial for the outer cover to have a three-dimensional shape which forces the additive into the central core in a predetermined direction upon application of the compression force before and / or in case of rupture of the outer cover. The movement of the additive can contribute to the
rupture of the outer cover, as the additive can apply pressure to the cover.
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 outer shell is formed from a single piece, instead of being formed by sealing two or more parts together,
The additive release component can be further promoted to directionally release the additive by means of a line, a point, and / or an area of weakness in the outer shell of the additive release component. This weakness may be configured for rupture in preference to the remainder of the additive release component when compressive force is applied to the component. In some embodiments, the line, point or area of weakness is created by virtue of the three-dimensional shape of the outer shell, rather than by the formation of holes or grooves in the material of the outer shell. In addition, or alternatively, the additive release component may comprise two different materials, one of which may be inherently more susceptible to breakage than the other.
The additive release component can be a capsule, as shown in the embodiments of the appended figures. The capsules generally comprise an outer shell, which may be made of gelatin, and an inner core comprising the additive.
Figure 1 shows a smoking article (10) comprising a cylindrical rod of smoking material, in this case tobacco (11), and a filter (12). The filter (12) comprises a substantially cylindrical plug of filter material (13), which is wrapped in a plug cover (not shown).
The rod of smokable material (11) is aligned with the filter (12) in such a way that the end of the tobacco rod (11) abuts the end of the filter (12). The rod is wrapped in a paper cover (not shown), and is attached to the filter (12) by the nozzle paper (not shown) in a conventional manner.
An additive release component (14) comprising an additive (15), which in this embodiment is a flavor (eg, menthol), is located within the filter (12). In the embodiment shown, the additive release component is a gelatin capsule. The additive release component has an ovoid (or egg-shaped) configuration, which has a first end
(14a) having a more rounded shape, and a second end (14b) having a more pointed shape.
The ovoid additive (14) release component is located substantially within the center of the filter (12), with the longitudinal axis of the additive release component (14) corresponding to the longitudinal axis of the filter (12). The ovoid additive release component is aligned so that the more rounded end (14a) faces the distal end (tobacco rod) of the filter, and the more pointed end (14b) faces the mouth end of the filter. Due to the shape of the additive release component and the engineering of the lines of weakness in the structure of the additive release component (not shown), the pointed end (14b) of the additive release component is more susceptible to rupture under the force that the rest of the additive release component (14).
In use, the compression force exerted on the filter (12) in the region of the additive release component (14), as shown by arrows A in the accompanying figure, causes the breakdown of the additive release component, and the release of the flavorant (15). Due to the shape of the additive release component, and the specific structural weaknesses within the wall of the additive release component
ovoid (14) at the pointed end (14b), rupture occurs in a predetermined manner, and the flavor is released from the additive release component in the material filter (13) in the direction of the mouth end of the filter. Substantially none of the contents of the additive release component (14) enters the filter material (13) at the sides or end of the tobacco rod of the additive release component.
Therefore, due to the shape and areas of weakness in the structure of the additive release component, the additive carrying the additive release component is directionally released in a controlled manner in a predetermined direction.
In some embodiments, the additive release component may comprise a sponge-like porous material, which may be compressible. The additive may be distributed within the sponge type material, and, optionally, absorbed by the sponge type material, which may release the additive by diffusion, or when compressed. A foamed material, which may be a body of absorbent material impregnated with the additive, is progressively compressible and is configured to release at least a portion of the additive contents when a part is compressed. The spongy material may comprise a matrix with a structure, closed cell, in
particular, a closed cell foam structure. The closed cell foam defines a matrix having a plurality of small cavities that may contain additive. The cavities are closed by the foam material, retaining the additive until its selective release. Upon application of a compression force, the closed cell foam can be configured to release additive.
The foamed material can be coated with a second material, which can form an outer covering comprising the sponge-like material. This outer material can function to retain the smoke modifying material within the sponge type material until the release of the contents is desired, at which point the external force exerted by the user can break the outer cover and tighten the additive from of the sponge type material.
In other embodiments, this sponge type material can be replaced by any porous material that is capable of carrying an additive. This material can be, for example, an adsorbent material, or a gel material.
In some embodiments, the additive release component is arranged so that by virtue of the application of the compressive force, the additive is ejected, by jets or driven, optionally
driven with force, from the additive release component. For example, the additive release component can be configured in such a way that the additive is released through a small region of the component. Therefore, in response to the compressive force, the additive can be expelled from the additive release component through this small region. In this way, the additive can be deposited further from the additive release component than is possible when the additive is released from known additive release components, and / or can be deposited over a larger area, and / or it can be deposited on a predetermined area of the filter.
In some embodiments, the additive release component or components may additionally be carried in a second additive release component, or a cover, or the like. This may allow greater control over the directional release of the additive. It can also provide greater protection against accidental or premature rupture, or accidental entry. In this way, for example, the single wall or multiwall additive release components can be used to adapt the stability, strength, resistance to breakage, processing of
the ease in manufacturing, etc., of the additive release component.
The additive release component may comprise a core, which may be divided into two or more separate chambers, for example by means of one or more partitions or other internal barriers. The partitions or barriers may be composed of the same material as the additive release component, or a different material may be used. The partition or barrier may be frangible, or may be highly resistant to fracture, for example because they are very robust or flexible.
The separate chambers of the core of the additive release component can comprise the same additive or different additives. The chambers may also comprise multiple reagents, one or more of which may not function independently as an additive, but the reactants react or mix with each other to form an additive. The two more additives can react chemically, for example, to produce an exothermic or endothermic reaction. The additives can be an organic acid and an alcohol that react to form an ester.
The additive release component can have a crush resistance of between 0.5 and 2.5
kp, for example, between 1 and 2 kp. Higher and lower crush strengths may be possible, for example, when the additive release component is incorporated into the smoking article in combination with a secondary element, which is a support structure as discussed below. Such a structure can facilitate the crushing or breaking of the additive release component, which allows components with higher crushing strengths to be used.
The size of the additive release component may be dependent on the volume of additive required, which in turn may depend on a number of factors, including the additive power and the degree of smoke modification desired.
It may be preferable that the volume of the additive release component be as large as possible, so that as much additive is provided as possible, to modify the smoke significantly as possible. The additive release component should not be so large however, acceptable filtration or drainage characteristics of the smoking article or filter of the smoking articles are not provided. In addition, as the size of the additive release component increases, it also increases
the risk of damage and / or release of accidental additive from the additive release component.
When the additive is released from the known additive release components, the release can be produced from any region on the surface of the additive release component. Therefore, the additive can be released from the additive release component in any direction into the surrounding material of the smoking article. The additive may additionally or alternatively be released generally with relatively little dispersion from the site of release of the additive release component. On the other hand, the extension of this additive version is not predictable, and may, for example, be dependent in part on the force applied to the additive release component. Since the direction and magnitude of the release of additive from known additive release components is not predictable, then the amount of additive provided within the additive release components must be greater than what is necessarily required with the additive. In order to guarantee the deposition in the desired areas of the smoking article. Consequently, the additive release components themselves must also be larger. However, the additive is released directionally from the release components
of additives disclosed in a predetermined, controlled and predictable direction. Therefore, the additive distribution is more efficient, and additive release components smaller than previously possible, can be used. Alternatively, the additive release components having sizes similar to those previously used can be used to deliver a significantly greater amount of additive to a desired location within the smoking article.
In some embodiments, the additive release component may be disposed longitudinally within the smoking article or smoking article filter, as shown in accompanying Figure 1. That is, the longest dimension of the additive release component can be substantially parallel to a longitudinal axis of the smoking article.
When the additive release component is aligned with a longitudinal axis of the filter, the additive can be released from the component in a direction parallel to a longitudinal axis of the filter. In effect, the additive can be released in the filter in any specific direction, and can be directed towards a particular region of the filter. The region can be, for
example, a cavity, a particular region of the filter material, or a peripheral region of the smoking article filter. The region in which the additive is released may comprise an active component, such as a second additive, which may or may not be retained by an additive-releasing component.
In some embodiments, the length of the additive release component can be between 1 mm and 15 mm, and preferably between 3 mm and 10 mm. The diameter may be within the range of 0.1 mm to 4 mm, and more preferably between 1 mm and 3 mm.
If a large amount of additive is required, multiple additive release components can be used. The additive release components can be all of the directional release additive release components, or can be a combination of known release and directional release additive components. The additive release components may have the same or different shapes, and may be the same or different sizes. When multiple additive release components are used, they may contain a similar additive or a combination of different additives. The multiple components of additive release can release additive in it
direction, one towards the other, or towards a common objective area, for example.
The multiple additive release components can be designed to release additive substantially simultaneously in response to a single application of compressive force on the smoking article. Alternatively, when multiple additive release components are present, the smoking article may require a number of sequential force applications for the release of the additive from all the additive release components. The additive release components may be arranged to directionally release the additives in substantially the same location within the smoking article, or each additive release component may have a different target area than the directional release.
The smoking article may comprise two, three, four or more additive release components. Multiple additive release components may be located, for example, at regularly spaced intervals along the length of the smoking article. Alternatively, multiple additive release components can be located as a group, for example, in the filter of the smoking article. In some modalities, the release components of
Additives can be located within a cavity formed between two sections of the filter material.
The additive directional release of the additive release components in smoking articles according to the invention can be achieved by means of the additive release component having a particular shape. Different three-dimensional shapes have an inherent ability to release their contents in a predictable manner when exposed to a force, such as a compressive force. Therefore, different forms of additive release components can be used to ensure the directional release of additive in a predetermined highly controlled and predictable shape and direction.
Generally, this may involve the use of additive release components asymmetrically, which possess an inherent ability to release additive in a predictable manner, as a consequence of its asymmetry. The additive release component can, for example, be approximately ovoid (as shown in Figure 1 below), conical, hemispherical, trapezoidal, pyramidal, and so on. In some circumstances, however, additive release components can be used more regularly, such as ellipsoidal oblate, cubic, etc.
In some embodiments, the additive release component is non-spherical. The additive release component may or may not have a "cigar" shape, comprising a cylinder with domed ends, such as may be used, for example, for release components in the pharmaceutical industry.
The lines, points or zones of weakness may, in addition, be provided within the structure of the additive release component, to further ensure that the release follows a desired pattern, and the additive is released in a predetermined direction.
Such predetermined areas of weakness can be provided in a number of ways. For example, the additive release component can comprise an outer cover, which can be weakened or provided with increasing strength in the desired areas. The strengthening of the components of release of additives in certain areas can be achieved, for example, by providing an increase in the thickness of the cover in the selected areas. Points of weakness can be introduced through a region of thickness of your helmet, or by means of marked lines.
The additive release components comprising two different materials can be used, where the materials inherently possess capabilities
different to release additive under the application of force. In this case, the less elastic material can form a zone or window, from which point the additive is released directionally when force is applied to the additive release component.
The manner in which the additive release component is formed can also be used to provide a directional release of predictable additive. The additive release component can, for example, be a multi-part additive release component, comprising a series of sections joined by one or more seams. In this case, the additive release component can be constructed to break along a seam length. In some alternative embodiments, the outer cover of the additive release component is formed as a single part.
The core can be divided into two or more (for example, 3, 4, or 5) separate chambers, for example by means of one or more partitions, or other internal barriers. In this case, the separate chambers of the core may comprise the same additive, or different additives. The chambers may also comprise two reagents, one or both of which may not function as an additive, but the reactants react or mix together to form an additive.
In some embodiments, the additive release component can be incorporated into the smoking article in combination with a secondary element that functions to further ensure that the additive is released from the additive release component in a predetermined direction.
The secondary element may function to direct the force applied to the smoking article in the additive release component in a particular manner. For example, the secondary element may be a shield, which prevents the force from being applied to a particular area of the additive release component. The secondary element can provide a reaction surface against which the additive release component can be compressed. The secondary element can alternatively focus the force applied to the smoking article in a particular area of the additive release component.
The secondary element can be an additive release component support structure. A support structure is a structure that supports an additive release component and that can be placed inside a smoking article. The support structure of the additive release component can allow controlled release of the additive from the
additive release component. The support structure may function to focus the force applied to the smoking article in a particular area of the additive release component. For example, the support structure may comprise a peak or point which, when force is applied to the smoking article, is brought into contact with the additive release component and thereby centers the force over a predetermined area of the release component. of additive.
In addition to assisting the release of additive in a predetermined direction, the support structure can allow greater control of the release of the additive from the additive release component. For example, the release can be controlled as to the time of release, the amount of release and / or the duration of the release.
Figures 2A and 2B show an additive release component (20) according to a second embodiment, wherein the additive release component is within a support structure (21).
In the embodiment shown, the additive release component is a gelatin capsule. The additive release component has an ovoid (or egg-shaped) configuration, which has a first end
(20a) having a more rounded shape, and a second end (20b) having a more pointed shape.
The outer circumference of the support structure of the additive release component (21) coincides with or is slightly smaller than that of the smoking article in which the support structure is to be used. The support structure (21) has the shape of a hollow cylinder or ring having a series of axial corrugations (22). In the modality shown, the support structure has 8 corrugations. In other embodiments, the support structure may have between 2 and 16 undulations. For example, the support structure may have 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, or 15 corrugations.
Stated another way, in some embodiments, the supports of Figures 2A and 2B can be described as a petaloid shape having a plurality of attached petals or lobes. Each petal or lobe includes a radially outward segment and two generally radial segments. The radially outward segment has a radially outward surface that is adapted to contact the i cylindrical surface of the smoking article, and an opposing radially i surface. The surface radially outward has a first and a second end, each of the
which is coted to an end portion radially outward of one of the generally radial segments. Each generally radial segment, as illustrated, includes the aforementioned radially outward end portion and a radially inward end portion. The radially inward end portions of each petal or lobe are attached to the radially inward end portion of an adjacent petal or lobe.
This aid can serve to capture and retain an additive release component by being slightly radially expanded.
On the outer circumferential surface of the support structure of the additive release component (21) the corrugations are in the form of axial grooves (23). On the i surface of the support structure, the corrugations have conical ends (24), which project into the central core of the support structure (21).
As shown in Figure 2B, the additive release component (20) can be positioned within the center of the support structure of the additive release component (21), such that the longitudinal axis of the release component of the additive (20)
corresponds substantially with the central axis of the support structure (21).
The ends of the projections (24) of the support structure are shaped to receive the additive release component (20). In particular, the distance between the conical ends of the opposing projections (24) is greater than the diameter of the capsule (20). The capsule is retained within the support structure of the additive release component by means of flanges (25) on the projections (24).
The axial corrugations (22) reduce the stiffness of the support structure of the additive release component (21), in particular in response to the compression force applied to the support structure of the additive release component in any lateral direction. In response to such a force, applied for example by the user's fingers, the support structure of the additive release component (21) deforms in an approximately circular fashion to a more elliptical cross-sectional shape.
In use, the deformation in response to the compression force reduces the distance between at least a pair of opposing projections (24) of the support structure (21). The force is transmitted through the projections
(24) to predetermined locations on the surface of the rounded end (20a) of the additive release component.
The pointed end (14b) of the additive release component is more susceptible to rupture under the force than the remainder of the additive release component (14) due to the engineering of the lines of weakness in the structure of the release component of the additive. additive (not shown).
When a compression force is applied to the support structure (21), the component (20) breaks at the pointed end (14b) in a predictable manner, and the additive is directionally released in a predetermined direction.
Figure 3 shows an exploded view of a smoking article comprising an additive release component (20) according to the second embodiment located within a support structure (21). The article for smoking comprises a rod of smoking material (26), and a filter (27). The filter (27) is a triple filter arrangement, wherein the support structure (21) that supports the additive release component (20) is located between two sections of cellulose acetate filter material, (28) and (29) The filter sections are combined to form the filter (27) by means of a plug cover (not shown), and joined
to the smoking material rod (26) by means of a nozzle paper (not shown) in a known manner.
In use, the force exerted on the filter (27) in the region of the support structure (21) in any lateral direction, by the user, causes the deformation of the support structure, as described above, and the release of additive from the additive release component (20) in a predetermined direction.
The size and shape of the support structure of the additive release component are preferably determined in combination with the size and shape of the additive release component that is used. In this way, the additive release component can be supported by the support structure, and the support structure can offer physical protection for the additive release component until such time as the release of the additive is required.
In one embodiment, the support structure of the additive release component has a cross-sectional shape that is substantially similar to that of the smoking article wherein the support structure is to be used. For example, support structures for use in conventional cigarettes can be circular in cross section. The reason for this is that the
Support structure can also function to provide the form, format, or strength to the smoking article.
The support structure of the additive release component may comprise on its outer surface one or more shins, grooves, raised elements, or any other deviation from a smooth surface. In addition, or alternatively, the support structure may be hexagonal or another polygonal, elliptical or irregular shape in cross section, instead of circular. Such elements may be detectable to the user of the smoking article, and may therefore provide an indication of the position of the support structure of the additive release component in the smoking article or the filter of the smoking article, and the region of the support structure to which the activation force must be applied in order to induce the release of additive from the additive release component. The support structure of the additive release component can also provide feedback to the user about the fact that the additive has been released from the additive release component. The feedback may be in the form of an audible sound, and / or a detectable change in the conformation of the support structure.
The support structure of the additive release component can induce the release of the additive from the additive release component through any possible mechanism. The support structure can be configured to transmit the activation force to the additive release component to provide a pumped release, a directional release, a multistage release or a single additive release. The type of release depends on the type and particular form of the support structure and the additive release component used, and the materials from which they are made.
The support structure of the additive release component can be a molded plastic structure. In some embodiments, the support structure is made of a biodegradable plastic, such as PLA (polylactic acid), CA (cellulose acetate) or PVOH (polyvinyl alcohol). However, the support structure could, in principle, be produced using any moldable plastic, ceramic, starch, paper, or other suitable material known to the person skilled in the art.
The support structure of the additive release component can induce the release of the additive from the additive release component into a single
dose, in multiple doses, or by means of a variable release, for example where the release is proportional to the intensity or duration of the force applied to the support structure. This can be achieved by appropriate selection of the material from which the support structure is manufactured. For example, if the support structure is molded from a flexible plastic, after application of the force, after activation, the support structure can be returned to its original conformation. In this case, depending on the nature of the additive release component, additional additive may be released from the additive release component for subsequent strength requests to the support structure. On the other hand, if the support structure is made of a rigid material, such as a rigid plastic, then, as the support structure is activated, it may break. Such an arrangement can limit the support structure of a single activation, and therefore the additive release component can administer a single additive release.
In some embodiments, the secondary element may function to directly assist the directional release of the additive from the additive release component. For example, the secondary element can be a funnel, a channel, or an adsorbent material, which helps
the directional release of the additive from the additive release component. In embodiments in which the additive release component is present in the filter of a smoking article, the directional release can be improved by the use of a breathable element, such as an absorbent material in the filter of the smoking article. In some embodiments, the absorbent material is more absorbent than the filter material, which may be, for example, a fibrous tow such as cellulose acetate. For example, the breathable element or elements may be placed adjacent to the additive release component within the filter in the region where the directional release of the additive from the additive release component is desired. In this way, the breathable element can extract the additive in the desired direction.
The breathable element, optionally comprising an absorbent material, can also be used to facilitate transport of the additive in a particular direction, after the additive has been released from the additive release component. The additive can permeate through the breathable element at a faster rate than it can penetrate through the filter material. Alternatively, or in addition, the additive may preferably be extracted throughout or through
of the breathable element. Therefore, the breathable element can dictate the direction in which the additive is mainly dispersed, and / or can affect the traveling distance. For example, the incorporation of a breathable element of a particular shape and in a particular position, can result in the transport of additive in a particular direction. Thin strands of absorbent material are particularly effective as a breathable element for transporting additive over longer distances. For example, one or more strands of absorbent material can be irradiated from the additive release component and provide paths along which the additive can be transported. The additive may even be directed to the external surface of the article to smoke in this manner.
Any suitable absorbent material can be used, for example, straight cellulose acetate wire, other cellulosic materials such as hydroxymethyl cellulose, starch, or polyvinyl alcohol foam can be used.
In some embodiments, the additive release component can be constructed of a frangible material. The additive release component is generally an additive release component. In one embodiment, the additive release component is
It consists of a polyvinyl alcohol of low solubility, high molecular weight. A number of suitable alternative materials are known, and by way of example, the additive release components typically used in the pharmaceutical industry can be used. Such additive release components can be based on being gelatin, for example, or they can be formed from a polymeric material, such as modified cellulose. One type of modified cellulose that can be used is hydroxypropylmethylcellulose. Many biodegradable materials are known that may be suitable for use in the production of additive release components and these include high molecular weight polyethylene glycols, polylactic acid, Plastarch material, polycaprolactone, polyglycolide, polyhydroxyalkanoate, such as poly-3- hydroxybutyrate, and bioplastics derived from zein.
Alternatively, the additive release component may comprise a hollow food material, such as, for example, paste, or extruded hollow tube of reconstituted tobacco material. The interior walls of the additive release component material can be advantageously coated with a varnish or waterproof material, such as silicone, to preserve the stiffness of the material of the additive release component.
by preventing the absorption of, or degradation by, the liquid content over a prolonged period.
The additive release component can alternatively be composed of a wax, resin, natural or synthetic rubber, latex or plastic material that retains its shape and resistance at room temperature and at the smoking temperature, but which is breakable after the application of a force external Examples of suitable waxes include beeswax, candelilla, carnauba, shellac wax, Caranday, sugarcane wax, miral wax and petroleum wax.
Suitable resins from which the additive release component can be composed include epoxy resins, terpene resins, petroleum resins, ester gum, phenolic resins and resins based on rosin. Preferred gums include gum arabic, locust bean, guar, alginates, carrageenan and pectin.
In some embodiments in which the capsule comprises a sponge-like porous material, any suitable sponge type material can be used. The foamed material, which may be a foam material, may be a foamed plastic polymer such as polyvinyl alcohol (PVOH).
The additive release component comprises an additive, which can be any substance that can be
added to the path of the smoke flow, for example, to modify the composition or properties of the smoke.
The additive retained within the additive release component can be a deodorant, a diluent, an adsorbent, or any other substance that is capable of modifying the gaseous flow. The additive can be water. When local regulations permit, the additive may be a flavoring agent.
As used herein, the terms "flavor" and "flavoring" refer to materials that, where allowed by local regulations, can be used to create a desired flavor or aroma in a product for adult consumers. They may include extracts (eg licorice, hydrangea, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, menthol, Japanese mint), anise, cinnamon, grass, wintergreen, cherry, blackberry, peach, apple, drambuie, bourbon, scotch, whiskey, mint, mint, lavender, cardamom, celery, husk, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cinnamon, cumin, cognac, jasmine, ylang-ylang, sage, fennel, pepper, ginger, anise, cilantro, coffee, or a peppermint oil of any species of the genus Mentha), flavor enhancers, bitter receptor site blockers, site activators or stimulants
of sensorial receptor, sugars and / or sugar substitutes (for example, sucralose, acesulfame potassium, aspartame, saccharin, cyclamates, lactose, sucrose, glucose, fructose, sorbino, or mannitol), and other additives such as charcoal, chlorophyll , minerals, botanicals, or agents to refresh your breath. They can be imitation, synthetic or natural ingredients or mixtures thereof. They can be in any suitable form, for example, oil, liquid or powder.
In some embodiments, the additive comprises mentho1 or water.
The taste may be a tobacco flavor. When the flavor is administered in liquid form, the flavor of the tobacco could be derived from tobacco extract. When the flavor is derived from a solid product, the product could be shredded tobacco sheet, in particles or in granules, or in the form of reconstituted tobacco sheet material.
The additive can be a solid, such as a powder, a liquid, such as a liquid flavorant, deodorant, water, etc., or a gas, such as an aromatic composition.
The method of manufacturing the additive release component can be dependent on the precise composition and the required shape. Any suitable manufacturing method can be used. For example,
Techniques can be used that include blow molding, injection molding, 3D printing and the use of rotary dies. A combination of techniques can be used.
The additive release component can be colored. For example, the additive release component may comprise a coloring agent. The coloring agent can be used to make it easier to locate the additive release component within the smoking article or the filter of the smoking article during the manufacturing process. Alternatively or additionally, the coloring agent can provide an interesting aspect for the smoking article, in particular if the release component of the additive is intended to be only partially enclosed within the smoking article, or if, for example, the nozzle paper is intended to have a transparent window portion.
Alternatively, or in addition, the additive retained in the additive release component may be colored. This can give the user an additional, visual indication that the additive has been successfully released, since the additive can be seen to be released directionally from the additive release component. This can be particularly useful if the additive release component comprises a
combination of additives, wherein one of the additives is colored, and thereby serves to indicate the release of another colorless additive.
When the additive is colored, it may be desirable for the additive-releasing component to directionally release the additive in a region of the smoking article or the filter of the smoking article in which the color was observed. For example, the additive may be directionally released in a peripheral region of the smoking article, such as a circumferential region or toward the mouth end. The color additive can be directionally released in a section of the smoking article that is visible through a portion of the transparent window.
In some embodiments, the smoking article may comprise a transparent window that may allow the display of the additive release component within the smoking article, such as within the filter. In this way, the user may be able to visualize the additive release component within the filter, and may be able to visually determine if the additive has been released.
To produce the effect of a transparent window, the nozzle paper or other cover may comprise a single piece of transparent material, which
may be, but is not limited to, one of polypropylene, polyvinyl chloride (PVC), cellulose acetate film, polyethylene terephthalate (PET), polyethylene oxide (PEOX), polyethylene, cellophane, Natureflex ™, polylactic acid, Plastarch material, polycaprolactone, polyglycolide, polyhydroxyalkanoate, such as poly-3-hydroxybutyrate, and bioplastics derived from zein. The tipping wrapper or other paper may have an opaque coating on certain parts and leave a transparent uncoated section defining the window.
The additive release component can be manufactured using any suitable method, the method of manufacturing the additive release component is clearly dependent on the precise composition and packaging required. Any suitable method of manufacturing the additive release component can be used, including techniques such as co-extrusion, spin coating, coacervation, interfacial polymerization, solvent evaporation, and ring jet forming.
In some embodiments in which the additive release component is a seamless capsule, the capsule can be produced using a coextrusion process. The co-extrusion process is a synchronous extrusion of the two liquids that subsequently form the
cover and the contents of the capsule (or "core"). The first step (co-extrusion) involves the formation of a droplet having the liquid core material inside the material of the liquid shell. After the co-extrusion step, the "capsule" is solidified by cooling or by immersion in a curing agent, for example. The capsules can then be subjected to various treatments, such as washing, removing excess liquid, dyes, application of additional coatings, etc.
Alternatively, a ring molding jet technique can be used. This method uses two concentric jets to eject an inner jet of liquid core material and an outer jet of liquid shell material. The fluid stream is broken into droplets and the liquid coating material solidifies by phase transition induced by the presence of crosslinking ions, pH differences, temperature changes, etc.
In some embodiments in which the additive release component comprises a wax capsule, the capsule may be formed, for example, by a method comprising freezing a solution of the liquid core material until small crystals are formed. According to this method, after the crystals are left
They fall into molten wax and are removed by spatula after a wax covering has formed around the cold crystals. The frozen core material gradually becomes liquid as the coated capsule reaches room temperature.
Foam-type foamed materials can be manufactured using a foam extrusion process.
The additive release component can be incorporated at any location within a smoking article, for example, the additive release component can be located within the filter of a smoking article.
Smoking articles generally comprise a rod of smoking material, and a filter. They extend in a longitudinal direction from a distal (lit) end, from where the smoke is introduced into the smoking article, to one end of the mouth. A consequence of the directional release is that the additive can be directed to a specific region of a smoking article or smoking article filter. The additive release component can be configured to directionally release the additive in a direction aligned with the longitudinal axis of the smoking article, in other words, in the direction of the mouth end or the distal end. The release in this region of the article
for smoking you can maximize the degree of interaction of the additive with the smoke.
The article for smoking may comprise one or more additive release components that are arranged to release additive directionally to a particular region of the smoking article or the smoking article filter, which may be any region of the smoking article or the smoking filter. article for smoking.
This region may comprise a material that is activated by the additive released from the additive release component. For example, this material may comprise a solid which is activated when it is in solution, and is therefore activated by the action of the additive in the form of water or a specific solvent.
The target region of the directional additive release may be a cavity in the center of the filter, which may or may not comprise other active materials. For example, the cavity may comprise crystalline flavorant, which may be activated when the additive in the form of a solvent is released directionally into the cavity to contact the crystals. Alternatively, the cavity may comprise a material that is sensitive to the additive in the form of water, for example, a material which upon contact with water changes color, dissolves, makes a sound, emits a taste or a smell, etc.
The particular region to which the additive is directed may be a region of filter material comprising a solid material in the form of small granules evenly distributed within the material. Such an arrangement may be useful, for example, when a granular crystalline flavorant is to be used in combination with an additive-releasing component comprising a solvent additive. In this case, a plurality of additive release components can be used, in which the additive can be sequentially released to provide flavorant for the duration of use of the smoking article. In this arrangement, the additive can be directed to the same or different regions of the filter material containing granules.
The region to which the additive is directed can be a peripheral region of the smoking article or the smoking article filter, such as a region on or near the circumferential surface of the smoking article, or the mouth end of the filter . Such an arrangement may be suitable, for example, when the additive is a dye, to provide an interesting aspect for the smoking article, and / or to provide a visual indication that the additive has been released, for example, when the additive release comprises a
combination of a colorant in combination with a second additive. This arrangement may also be suitable when the additive is an odorant, to facilitate diffusion of the odor outside the smoking article.
A smoking article or smoking article filter may comprise two or more additives, each maintained within a separate additive release component. This arrangement may be suitable, for example, when the two or more additives react chemically, or where the additives are subject to oxidation, diffusion, or other means of loss of intensity over time.
The two or more additive release components may be arranged to directionally additive additive to each other. Such an arrangement can be useful, for example, when the additives react chemically, such as to produce an exothermic or endothermic reaction, or a reaction in which an odor or a gas is evolved, or a visual effect of color or another is produced. kind.
The two or more additive release components can be arranged to additive additive directionally to a common region of the filter. This may be suitable when a significant amount of additive is required to be supplied to a particular region of the filter, for example, when the additive is
water, and the destination region of the filter comprises a water-sensitive material, such as a water-swellable, water-soluble, or water-degradable material.
Since the additive release components of the invention are designed to release additive directionally, then the orientation in which the additive release component is inserted into the smoking article or the smoking article filter must be controlled.
The specific form of the additive release component of the invention can aid the insertion process of the additive release component. For example, when the center of gravity of the additive release component is not at the geometric center of the additive release component, such as is the case with the ovoid additive release component shown in the accompanying Figures 1 and 2, then the additive release component, of course, assumes a particular orientation, and this property can be used to ensure that the additive release component is inserted into the smoking article in the desired orientation.
In general, the additive release component can be inserted into the filter of the smoking article, and any suitable method can be used to
insert the additive release component into the filter. A suitable apparatus may, for example, include a means for supplying a continuous flow of filter material from a source of this type of material (eg, a bale, coil, or the like). The apparatus may further include an insertion unit for the additive release component for inserting or depositing the individual additive release components at predetermined intervals within the filter material. The filter material having additive release components deposited thereon can then be received in a rod-forming means to provide a continuous rod which can subsequently be subdivided into the desired length at predetermined intervals to form the individual filters of the rod. invention
Any suitable alternative technique can also be used if applicable. For example, the additive release component can be inserted into a cavity within the filter, or known dual or triple filter combination techniques can be used. The component can be incorporated into a filter using a vertical feeding method.
The embodiments of the invention are configured to comply with laws and / or regulations
applicable, such as, by way of non-limiting example, the rules relating to flavors, additives, emissions, constituents, and / or the like. For example, the invention may be configured such that a smoking article of the application of the invention is compatible with applicable standards before, during and after the release of a smoke modifying agent from a capsule.
