Description

supporting structure

The present invention relates to an additive release element support structure for use in a tobacco product.

As used herein, "tobacco products" include smokable products such as cigarettes, cigars, and cigarillos, whether tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes, and heated but not A product based on a heat-not-burn product (i.e., a product containing a flavoring material produced from a cigarette raw material by providing heat energy of the raw material without causing it to burn). In general, tobacco products are provided with filters for eliminating smoke components.

It is known to provide an additive release element that contains an additive (e.g., a flavoring agent) inside the tobacco product. By applying a force to the exterior of the tobacco product, the smoker can trigger the release of the fragrance from the additive release element. Therefore, the desire of smokers to increase the flavor to smoke can be achieved by easily squeezing the tobacco product.

When the additive release element is in the tobacco product, it may be difficult for the user to release the additive. To overcome this problem, an additive release element can be used to make the additive easier to release. However, this additive release element can have the potential to increase the accidental release of the additive. Moreover, because the additive release element is typically disposed in the tobacco product, it may be difficult for the user to determine if the additive has been released from the additive release element.

According to a first aspect, there is provided a support structure for use in a tobacco product, the support structure being configured to initiate release of the additive from the additive release element when a compressive force is applied, wherein in the absence of a support structure The support structure changes the required compressive force to release the release of the additive from the same additive release element as compared to the desired force required to release the additive from the additive release element.

In a second aspect, there is provided an additive release system comprising a support structure according to the first aspect, comprising a support structure according to the first aspect, and an additive release element.

In a third aspect, a filter for a tobacco product is provided. The filter comprises a support structure according to the first aspect, or an additive release system according to the second aspect.

In a fourth aspect, there is provided a tobacco product comprising a support structure according to the first aspect, a support system according to the second aspect, and/or a filter according to the third aspect.

The additive release element support structure is a structure that can support the additive release element and can be placed in a tobacco product. The additive release element support structure permits, facilitates, and/or enhances controlled release of the additive from the additive release element. The release process can be controlled, for example, in terms of direction, mass, speed, timing, and/or duration of release. Additive release component The support structure can also provide a user feedback mechanism when the additive has been released from the additive release element.

Therefore, by using the additive release member support structure in the tobacco product, the user can easily release the additive from the additive release member when needed, and the release characteristics can be precisely controlled. In addition, when the additive release member support structure is actuated, the user can feel it, so it is believed that the additive has been released. Actuation of the additive release element support structure can also be associated with an acoustic, such as a click, which provides a further feedback mechanism for the user when the additive has been released from the additive release element.

The support structure can support an additive release element, for example, the support structure can be configured to receive an additive release element.

In some embodiments, the support structure secures the additive release element. The support structure can support the additive release element. For example, the support structure can be a shape to accommodate or clamp the additive release element, and/or the additive release element can be adhered or bonded to the support structure.

In some embodiments, a tobacco product can be made by inserting an additive release element into a support structure and then fabricating a tobacco product comprising a support structure.

In some embodiments, the support structure can have a generally cylindrical configuration, and in this case, the center of the cylinder can be configured to receive an additive release element.

The support structure can be actuated and used to initiate the release of the additive from the additive release element. The actuation action can be triggered by the application of an external force, such as by a compressive force.

The actuation of the support structure can be triggered by the application of an external force to the support structure, wherein the external force can be any form of force, such as compression or tension. In some embodiments, an external force can be applied to the support structure in an inwardly facing direction. In other words, when the support structure is placed in the tobacco product, a force (e.g., extruded tobacco article) can be applied to the outer surface (outer surface) of the support structure. In some embodiments, the support structure can have a cylindrical configuration and can apply a force to the curved peripheral surface of the support structure.

The external force applied to the support structure can be any kind of force, including compressive forces or tensions. For example, an external force can be applied directly to the support structure, or an external force can be applied to the support structure via other elements of the tobacco product, such as via one or more packaging layers, and/or one or more sections of filter material. The force applied to the filter can be transferred to the support structure placed therein by squeezing the surrounding filter material. Alternatively, a portion of the support structure can protrude from or near the surface of the tobacco article so that the force can be applied substantially directly to the support structure.

In some embodiments, the direction of extrusion is a plane that is perpendicular to the longitudinal axis of the tobacco article in which the support structure is bonded. Therefore, the support structure can be actuated by squeezing a suitable section of the tobacco product.

In some embodiments, the support structure is a solid profile article.

In some embodiments, the support structure can be provided with a hard reaction surface, ie the support structure is rigid, strong and/or difficult to bend. The support structure may be constructed from a single portion or a plurality of portions that are clamped together to provide sufficient rigidity to substantially actuate the subsequent compression action against the support structure such that the compressive force is transmitted to the additive release member.

In some embodiments, the force applied to the support structure is only transmitted and/or concentrated on a particular portion of the additive release element. In some embodiments, the support structure has an interior surface having a restricted area where it will contact the additive release element, such as due to the contour of the interior surface of the support structure. In some embodiments, it can be achieved by one or more projections located on the interior surface of the support structure, for example, which can pierce the additive release element. In other embodiments, the support structure can have a corrugated or wavy interior surface.

The support structure can include a deformable section. In some embodiments, the remainder of the support structure is substantially resistant to deformation due to the application of compressive forces. The deformable section can be elastic or plastically deformable. The deformable section can comprise a conical projection.

The deformable section can have the form of an articulated arm. Alternatively, the deformable section may be a section of the peripheral surface of the balloon support formed between two weakened sections in the surrounding surface.

In some embodiments, the deformable region of the support structure is not predefined.

The support structure can be provided with a reaction surface that is compressed against the additive release element. Additionally, or alternatively, the support structure can comprise a projection, such as a conical projection, wherein the actuation action is associated with the additive release element and the projection, for example, the conical projections will be compressed together or extrusion.

In response to an external force, the additive release element support structure can initiate the release of the additive from the additive release element via any possible mechanism. The support structure can be configured to deliver an actuation force to the additive release element via any suitable machine Constructed to initiate the release of the additive. For example, the release action can be a suction-type release, a directional release, a complex phase release, or a single release of the additive. For example, the form of release depends on the particular configuration and shape of the support structure and additive release element used, and on the material (substance) used for its manufacture.

The additive release element support structure can initiate the release of the additive from the additive release element in a single dose, multiple doses, or a variable number state, for example, proportionally to the duration or intensity of the force applied to the support structure. freed. This can be achieved by a suitable section of the material of the support structure being fabricated. For example, if the support structure is molded from an elastic plastic and actuated with the application of force, the support structure can return to its original configuration. In this case, depending on the nature of the additive release element, further additives may be released from the additive release element by subsequent application of force to the support structure. On the other hand, if the support structure is made of a non-flexible material, such as a non-flexible plastic, the support structure may rupture when actuated. This arrangement can limit the support structure to a single consistent action, so the additive release element can perform a single release action of the additive.

Actuation of the support structure can occur as the audible sound or sensible structural changes within the support structure occur. Therefore, the user can easily determine whether the additive has been released from the additive releasing member.

The support structure may comprise a molded plastic material such as polylactic acid, cellulose acetate or polyvinyl alcohol.

The size and shape of the additive release element support structure is preferably determined by the size and shape of the additive release element used in conjunction therewith. In this way The additive release element can be supported by the support structure and the support structure can provide physical protection of the additive release element until the desired additive is released.

Smoke that is drawn along the tobacco product can release the element support structure through the additive. Thus, in order to minimize the clogging of the smoke, when the additive release element is placed in the support structure, preferably the support structure is generally hollow and/or may include notches (gap) and/or channels to allow The airflow passes through the structure such that the support structure and the additive release element do not block the aerosol path and any flowing gas flow through the filter located therein. This blocking condition may be detrimental to the effect of the pressure difference.

The additive release element support structure can be smaller than the diameter of the tobacco article used therein. For example, the support structure can have a generally cylindrical shape with an outer circumference that can be smaller than the diameter of the accompanying tobacco article. Therefore, the support structure used in the filter of the oversized tobacco product can have a diameter of about 5 mm to 10 mm. In contrast, the support structure used in the filter of the ultra-thin tobacco product may have a diameter of about 3 mm to 7 mm.

In general, the additive release element support structure is generally between 3 mm and 12 mm in length, preferably between 4 mm and 10 mm, for example 5 mm, 6 mm, 7 mm, 8 mm or 9 mm in length. .

In an embodiment, the additive release element support structure has a cross-sectional profile that is substantially similar to the support structure used in the tobacco product. For example, the support structure used in conventional cigarettes can be an annular cross section. The reason is that the support structure can also have an effect on the shape, form or strength of the tobacco product.

In some embodiments, the additive release element support structure can have a large The size is smaller than the diameter of the tobacco product. In this case, one or more support structures may be present throughout the tobacco product.

In some embodiments, the support structure has a size that is substantially the same as the cross-sectional dimension of the tobacco article incorporated therein. In these embodiments, the support structure will not be surrounded by a layer of material, such as a filter material, or surrounded by voids or gaps. More specifically, for example, the support structure can be surrounded only by filter paper, wrapper and/or filter wrap, or other wrapper around the relevant portion of the tobacco product.

The additive release element support structure can comprise one or more hillocks, grooves, raised features or any different variations on the smooth surface on its outer surface. Additionally, or as an alternative, the cross-section of the support structure can be hexagonal or other polygonal, elliptical or irregular, rather than circular. The user of the tobacco product can perceive the component, thus providing a prompt for the location of the additive release member support structure in the tobacco product filter, as well as the region where the actuation force must be applied in order to trigger the release of the additive from the additive release member.

The additive release element support structure can be a molded plastic structure. In some embodiments, the support structure can be fabricated from a biodegradable plastic such as polylactic acid (PLA), cellulose acetate (CA), or polyvinyl alcohol (PVOH). In other embodiments, the support structure can use any moldable plastic, ceramic, starch, card, paper, fluted wrap, or other suitable material known to those of ordinary skill in the art. Made. In some embodiments, the material from which the support structure is made may be transparent or translucent.

In some embodiments, the additive release element support structure can be at least partially visible to the user, for example, via a transparent window portion in the filter paper. In this case, the support structure can be made of a transparent, colorless material. Alternatively, the support structure can be colored. For example, the support structure can comprise a colorant. Colorants can also be used during the manufacturing process to more easily indicate the location of the support structure in the filter.

The additive release element support structure can also provide consumer perceived utility upon actuation. For example, this can be achieved by an audible sound being emitted by the support structure upon actuation and/or by a perceptible shape change by actuating the subsequent support structure.

In some embodiments, the additive release element support structure can be fabricated from a process that is initially fabricated with a stem or tubular portion that is suitable for internal and/or external contours. For example, the stem or tubular portion can be extruded or can be shaped or stamped, for example, from a piece of suitable material. The stem or tubular portion is then slit or divided into individual units, each of which is a single support structure.

In some embodiments, the support structure includes a contoured tubular portion that will support and support the additive release element and have a cross-sectional profile. In some embodiments, the support structure will be an additive release element adapted to transmit a compressive force into the internal void. A compressive force is applied to the outer surface of the support structure, and then the compressive force is transferred to the surface of the additive release element. Where there is a local contact between the support structure and the additive release element, the force can be concentrated there. In some embodiments, the local transfer of force can be compared to the force required to cause the additive release element of the unsupported structure to rupture. The application of less force then causes the additive release element to rupture.

In some embodiments, the cross-sectional profile of the support structure has an air flowable through passage. The channel may be located between the support structure and the additive release element and/or to the exterior of the support structure, such as a recess or groove in the outer surface, which may be between the outer surface of the support structure and a portion of the tobacco product incorporated therein Formed with a channel.

In some embodiments, the support structure is a grooved tubular portion. For example, the grooves can be smooth, wavy, irregular, pointed, or bastion.

In some embodiments, the material of the support structure may comprise or consist of a sheet material, for example, comprising: cellulose acetate, which may be extruded or provided in the form of a sheet, and then subjected to a thermoforming process, For example, to provide a cross-sectional shape of the groove; cellulose diacetate, such as Clarifoil®, freely molded by thermoforming, or hot melt adhesive material, including EVA (synthetic vinyl) ), PU (polyurethane), metallocene catalyzed polymers, APAO (amorphous olefin copolymer), polydecylamine and block copolymers, such as Henkel Technomelt® (Henkel Industrial) ) Q2237 hot melt adhesive technology.

In some embodiments, the additive release element is coupled to the support structure prior to insertion into the predetermined portion of the tobacco product (also referred to as the additive release system). The action of insertion into the tobacco product can occur simultaneously with the assembly of the tobacco product.

In some embodiments, the support structure is adapted to cause an additive release element Once the support structure is inserted, the additive release element can be held in place by, for example, the shape of the blade or support structure. In some embodiments, the support structure comprises a deformable section that is deformable for insertion of an additive release element, the section then restoring its original configuration such that the additive release element is supported in the support structure At the office. The support structure supports the additive release element to help confirm that the two components are properly inserted into the tobacco product.

In other embodiments, the additive release element can be supported in the support structure by a friction fit. When the support structure and the additive release element are combined, the internal diameter of the support structure is not greater than the additive release element when they are side by side. The outer diameter.

In other embodiments, the stem or tubular portion can be inserted into the additive release element, wherein the stem or tubular portion is slit or divided into individual segments to form an individual support structure. The tubular or tubular portion is cut or divided and subsequently formed into a support structure that has been combined with the additive release element.

The additive release element is any device that can carry the additive and can release the additive when needed. The release action can be triggered by the application of an external force on the tobacco product, such as by the user's finger, via the additive release element support structure.

The additive release element can comprise a housing and a central core, wherein the additive is retained in the central core. The outer casing may be fragile, plastically deformable, or elastically deformable. The core of the additive support can be a simple cavity. Alternatively, the core in which the additive is supported may comprise a sponge-like material, an absorbent property material or a gel-like material.

The additive release element can comprise an outer casing and an inner core. The outer casing can be Fragile, elastic, deformable, or elastically deformable.

In the first to ninth drawings attached below, an embodiment is shown in which the tobacco product comprises a bladder portion containing an additive in the central core. However, in other embodiments, other forms of the additive release element can be used to transport the additive. For example, the additive release element can comprise a sponge-like material (as shown in Figure 10 attached), an absorbent material, a gel-like material, or any suitable material.

The additive can be released from the additive release element by any suitable method. For example, the release of the additive can be triggered by the force exerted by the user on the additive release element via the additive release element support structure. The force can be an external force, such as a compressive force applied by a user to squeeze a tobacco product or support structure. For example, the release of the additive can be associated with rupture of the additive release element, or alternatively, the additive release additive can be applied from an additive comprising a porous or sponge-like material.

In some embodiments, including the attached Figures 1 through 9, the outer wall of the additive release element can be made of a gel comprising an inner core filled with the additive.

In some embodiments, including the attached Figure 10, the sponge material is compressible and can be used to transport the additive. The additive may be distributed throughout the sponge material and optionally absorbed by the sponge material to release the additive when it is compressed. The spongy material can be a body that is impregnated with an additive absorbing material that is progressively compressible and configured to release at least a portion of the additive content when it is partially compressed. The sponge material may comprise a filler having a closed trough structure, Do not refer to the structure of the closed-cell foam. The closed cell foam is defined as a fill having a plurality of small cavities that can accommodate the additive. The cavities are closed by a foaming material to retain the additive until a selective release action is taken. The closed cell foam can be configured to release the additive when a compressive force is applied thereto.

The closed cell foam matrix does not require an outer casing to retain the additive, so the additive release element can be formed without the outer casing. However, the additive release element may alternatively comprise a coating on the surface of the sponge material that may form an outer shell surrounding the sponge material. The additional material may create the effect of retaining the additive in the sponge material until the contents are released as desired, while at the same time the outer shell is broken by the external force applied by the user via the support structure and from the sponge material Extrusion of the additive.

In some embodiments, the additive release element can be a porous material capable of transporting the additive. For example, the material can be an adsorbative material, or a gelatinous material.

The additive release element support structure can comprise a plurality of additive release elements that are similar or different from the additive release elements. In this example, the support structure can trigger the actuation of all of the additive release elements by a single actuating mechanism, or alternatively, the support structure can be designed to be transported independently by the separate actuating mechanism of the support structure. Dynamic additive release element. When a plurality of additive release elements are used, they can accommodate combinations of similar or different additives. For example, a plurality of additives can be chemically reacted to produce an exothermic or endothermic reaction. The additive may be an organic acid which reacts to form an ester and ethanol.

The additive release element can be a completely separate individual to the additive release element support structure, or can comprise an integral part of the support structure. For example, a portion of the support structure can be fabricated to include a sealed chamber that provides the additive release element and contains the additive.

The size and shape of the additive release element can be determined by the size of the support structure of the additive release element to be used. The size of the additive release element can also be determined by the volume of additive required. However, in order to have the actual situation of the additive release element in the filter, it is conceivable to maintain the filtering or aspirating characteristics of the filter which is unsatisfactory.

The length of the additive release element can range from 0.1 mm to 5 mm, more preferably from 2 mm to 4 mm.

When a plurality of additive release elements are used, the additive release elements can be the same or different sizes.

The additive release element can be constructed in a variety of physical forms. For example, the additive release element can be a balloon portion, which can be a single or multiple site balloon portion, a large balloon portion, a small balloon portion, a microcapsule portion, and the like. A number of distinct additive release element configurations are suitable, for example, the additive release element can be generally spherical (as described in the preferred embodiment), oval, elliptical, cylindrical, or any other shape.

In some embodiments, the support structure reduces the required compressive force to initiate an additive from the same additive release element as compared to the required force to release the additive from the additive release element without the support structure. Release.

Regarding the additive release element of the support structure used, it cannot In the absence of a support structure, manual compression is used to release the additive, but with a support structure, manual compression to release the additive. For example, the additive release element may comprise a housing having a rigid material that cannot be broken by application of a compressive force without a support structure, but may be broken by application of a compressive force with a support structure .

In the absence of a support structure, the user of the tobacco product is required to apply a greater amount of compressive force to create a fracture and/or deformation of the outer shell of the additive release element, as compared to the compression force required in the case of a support structure. .

Because the additive release element is actuated by the additive release element support structure, in some embodiments it can be more durable than the previously used additive release elements of the tobacco product. This is because the force exerted by the user's fingers is concentrated on a smaller area of the additive release element by the additive release element support structure, which enhances the strength of the force on the additive release element.

Conventional bladders that are unsupported and incorporated into the tobacco product filter typically have a comminution strength of no greater than 2.3 kp to ensure that the bladder is very fragile, allowing the consumer to apply without squeezing the filter. Too much pressure causes the capsule to rupture. For the same reason, sometimes, a conventional bladder having a pulverizing strength of not more than 2.1 kp or not more than 1.9 kp is preferably used. The force unit 1 kp is equal to 1 kg-force, which is approximately 9.8 Newtons (N).

In the case of an additive release element support structure, the release of the additive from the additive release element is facilitated, preferably reducing the compressive force that must be applied. Thus, in some embodiments of the invention, the additive release element of the additive release element support structure used has no greater than Crushing strength of 2.5 kp, 2.6 kp, 2.7 kp, 2.8 kp, 2.9 kp or 3 kp.

The pulverization strength referred to herein means the initial pulverization strength Ci of the additive releasing member measured before smoking (in a dry state), which is a digital type using LLOYD-CHATILLON (Lloyd-Chardron) The dynamometer (model DFIS 50, upper measurement limit 25Kg, minimum measurement unit 0.02Kg, accuracy error plus or minus 0.15%) is used for measurement, which continuously applies a vertical load on a particle point until it breaks. The dynamometer is attached to the gantry and the additive release element is placed in the middle of the plane raised by the manual wire screw arrangement. The pressure is then applied manually, and the dynamometer records the maximum force (measured in kg) at which the additive release element breaks. The rupture of the additive release element results in a release action that supports the additive in the element.

The additive release element support structure can comprise protrusions, protrusions, tips, conical edges, or other conical protrusions or regions having smaller surfaces that are subsequently contacted with the additive release element upon actuation of the support structure . In this manner, the external pressure applied to the support structure can be concentrated on a smaller area of the surface of the additive release element. For example, when the additive releasing element is a spherical capsule, the support structure can be directed to the force and radially through the center of the capsule by the conical projection, so the localization effect on the smaller area The force causes the puncture to rupture, which is the maximum that is most likely to break.

In some embodiments, the support structure increases the required compressive force to initiate release of the additive from the same additive release element as compared to the desired force to release the additive from the additive release element without the support structure. .

Therefore, the additive release component support structure is also helpful in the past. The use of less robust additive release elements in tobacco products. This is because the additive release element prevents accidental actuation and/or damage caused by support in the support structure. For conventional bladders that do not use a support structure, the minimum comminution strength of the bladder should generally be at least 0.5 kp, making the bladder sufficiently durable during cigarette manufacturing to resist premature or accidental chipping.

Thus, in some embodiments, the additive release element of the additive release element support structure used may have a comminution strength of less than 0.5 kp, less than 0.25 kp, or less than 0.2 kp.

Therefore, the additive release element support structure allows for a possible actuation error over a larger range of additive release elements than before. The additive releasing element used may have a pulverizing strength of between 0.1 kp and 3 kp.

The additive release element used has a frangible tip in an area where the additive release element support structure can contact the additive release element. Several methods can be used to achieve the elasticity of the local additive release element. For example, the additive release element can be an elliptical or ovoid pocket that, when exerting a force against the other in one direction, thereby creating a greater resistance to rupture. Alternatively, this local elasticity can be achieved using an additive release element that is specifically reinforced in a particular area. For example, the additive release element can be an additive release element having a thickened outer shell in a selected area. Naturally, a similar effect can be achieved by weakening the outer layer of the additive release element in a particular area.

In some embodiments, the additive release element can be a dual layer element. For example, the additive release element can be a capsule further having a second encapsulation layer, or a sheath or the like. This allows for better protection to prevent Actuated or damaged in advance or in advance, or accidentally leaked. In this manner, single or multiple outer wall additive release elements can be used to provide tailoring stability, strength, fracture resistance, convenience in filter manufacturing, and the like.

In the embodiment shown in the attached Figures 1 to 9, the additive release element support structure has specific structural features, such as arm 12, flange 25, or strut bracket 32, which is designed to accommodate Additive release element. However, in other embodiments, the additive release element support structure does not have any special design features for accommodating the additive release element. In this case, the additive release element can be easily adhered to a portion of the interior surface of the support structure. For example, in other embodiments, since the additive release element is limited to the support structure between the two filter segments of the composite filter, the additive release element does not use adhesion, but by other means Maintained in the additive release element support structure.

In some embodiments, the additive release element is a bladder made of a frangible material. In one embodiment, the additive release element is comprised of a low solubility, high molecular weight polyvinyl alcohol. Several known suitable alternative materials are listed below, and additive release elements are typically utilized by users in the pharmaceutical industry. For example, the additive release element can be a gelatin substrate or be composed of a polymeric material, such as modified cellulose. Hydroxypropyl methylcellulose can be used in one form of modified cellulose. Various biodegradable materials suitable for use in the preparation of additive release elements, including high molecular weight polyethylene glycol, polylactic acid, polylactic acid fiber materials, polycaprolactone, polyglycolide, Polyhydroxyalkanoates such as polyhydroxybutyl esters, as well as biodegradable plastics made from zein.

Alternatively, the additive release element may comprise a hollow food material, for example a hollow tubular extruded from a macaroni or reconstituted tobacco material. The inner wall of the additive release element material may advantageously be coated with a varnish or a water repellent material, such as a crucible, to maintain the rigidity of the additive release element material from absorption or decomposition upon prolonged contact with the liquid.

The additive release element may alternatively be constructed of paraffin, resin, natural or synthetic rubber, latex or plastic material that maintains its shape and is activated in addition to the additive release element support structure at room temperature and smoking temperature followed by rupture Strength outside the action. Examples of suitable paraffin waxes include beeswax, candelilla wax, palm wax, shellac wax, caranday, cane wax, waxwood, and petroleum wax.

Suitable resins include epoxy resins, terpene resins, petroleum resins, rosin glycerides, phenolic resins, and rosin-based resins. Preferred gums include gum arabic, locust bean, gum bean, alginate, carrageenan, and pectin.

In some embodiments, any suitable sponge-like material can be used for the additive release element comprising the sponge-like porous material. The sponge-like material may be a foamed material, which may be a foam of a plastic polymer such as polyvinyl alcohol (PVOH).

The additive release element can be colored. For example, the additive release element can comprise a colorant. The colorant can be used to more easily indicate where the additive release element and additive release element support structure are located within the filter during manufacture. Alternatively or additionally, the colorant can provide an interesting and attractive appearance of the tobacco product, particularly if the additive release element support structure or structure is intended to be only partially enclosed in the filter material, or if the filter paper is intended When there is a transparent window part. If a colored additive release element is used, it can be used in conjunction with a colorless transparent support structure.

Alternatively or additionally, the additive that is supported in the additive release element can be colored. This can give the user an additional visual cue that when the additive is seen to move outside of the additive release element, the additive has been successfully released. In particular, this is particularly useful if the additive release element comprises a combination of additives, one of which is colored and thus serves to reveal the release of other colorless additives.

When the additive is colored, it can cause the support structure to assist in the directional release of the additive into the area of the tobacco product or tobacco product filter, and color will be observed in the area. For example, the additive can be directionally released into the surrounding area of the tobacco product, such as the surrounding area or toward the mouth end. The colored additive can be directionally released to the section of the tobacco product that is visible through the transparent window portion.

The additive release element can be fabricated using any suitable method, and the method of making the additive release element depends on precise composition and construction requirements. Suitable additive release element manufacturing methods include techniques such as co-extrusion, spin coating, coacervation, interfacial polymerization, solvent evaporation, and annular jet flow.

In some embodiments, the additive release element is a seamless bladder and the bladder portion can be fabricated using a co-extrusion process. The co-extrusion process synchronizes two liquids that subsequently form the shell and the contents of the bladder (or "core"), in this case the additive. The first step (co-extrusion) is associated with droplets formed with liquid additives in the liquid housing material. in After the co-extrusion step, for example, the "capsule" is cured by cooling or by dipping into a curing agent. The bladder can then be subjected to various treatments such as rinsing, removal of excess liquid, coloration, additional coating applications, and the like.

Alternatively, a circular jet flow technique can be used. This method utilizes two concentric jets for ejecting the internal jet of liquid core material and the external jet of liquid housing material. The liquid phase is split into droplets and the liquid shell material is solidified by triggering phase transitions such as ion crosslinking, pH differences, temperature changes, and the like.

In some embodiments, the additive release element comprises a paraffinic bladder portion, for example, the bladder portion can be made from a solution comprising a frozen liquid core material until a small crystal is formed. According to this method, after the paraffin coating is formed around the cold crystal, the crystal is then dropped into the molten paraffin and removed by the spatula. When the coated bladder reaches the room temperature, the frozen core material gradually becomes a liquid.

The foamed sponge material can be produced using a foam extrusion process.

The additive that is supported in the additive release element can be a flavoring agent, a deodorant, an adsorbent, a diluent, or any other substance that can improve the smoke. In some embodiments, the additive can be menthol or water.

As used herein, "fragrance" and "fragrance" mean that the local regulations permit the use of ingredients that are intended to produce a predetermined flavor or aroma in an adult consumer's product. The raw materials may include extracts (eg, licorice, hydrangea, magnolia, chamomile, fenugreek, clove, mint, Japanese mint, fennel, cinnamon, vanilla, holly, cherry, berry, peach, Apple, liqueur, bourbon, scotch, whiskey, stay Lanxiang, peppermint, lavender, cardamom, celery, bitter tree, nutmeg, sandalwood, bergamot, geranium, honey concentrated flavor, rose oil, vanilla, lemon oil, orange oil, cinnamon, caraway, cogne Brandy, jasmine, ylang-ylang, sage, fennel, allspice, ginger, anise, coriander, coffee, or peppermint oil from any kind of mint), flavor enhancer, bitter taste receptor Broken agent, sensory enhancer or stimulant, sugar and/or sugar substitute (eg sucralose, potassium sulfonate (acesulfame), aspartame, saccharin, sweetener, lactose, sucrose, Glucose, fructose, sorbitol or mannitol), as well as other additives such as charcoal, chlorophyll, minerals, botanical ingredients, or breath fresheners. It can be an artificial, synthetic or natural ingredient, or a mixture thereof. It can be in any suitable form, such as an oil, a liquid or a powder.

The flavoring material can be a tobacco flavoring material. Here, the flavoring material is delivered in a liquid form, and the tobacco flavoring material can be obtained from the tobacco extract. Here, the additive is in a solid form, and the additive may be a filamentous, granulated or granular tobacco leaf or a reconstituted tobacco material.

The additive may be a solid, such as a powder, which may be a liquid, such as a liquid flavor, deodorant, water, etc., or may be a gas, such as a fragrance composition.

The additive may be in the form of granules, powder, granules, or any other suitable form of sorbent. In this case, preferably, the adsorptive property material has a particle diameter of less than 500 μm (micrometer), preferably has a particle diameter of less than 100 μm. More preferably, the adsorptive property material has an average particle diameter of less than 50 μm, and most preferably has an average particle diameter of less than 20 μm.

The filter may comprise a composite filter, in this case one of the filter sections, such as the mouth end, the central portion, or the tobacco rod end filter section may comprise a support system. The filter may comprise a plurality of support structures, for example, the filter may comprise 2, 3, 4, 5 or 6 support structures.

The filter may include an indicator for actuating the support structure to indicate that the force should be applied to the filter region or region.

In some embodiments, the support structures are vertically side by side and inserted into the longitudinal axis of the tobacco product, and the support structure substantially fills the cross section of the filter. In some In an embodiment, the combination of the support structure and the additive release element includes a path through which the airflow can pass, in such a manner as to provide a path through which the smoke and the venting airflow pass, preferably without the adverse pressure differential.

The support structure can trigger the release of the additive into the filter in any particular direction. This direction can be predetermined by the shape and structure of the additive release element and/or support structure. The additive can be directionally released toward a particular area of the filter. For example, the region can be a cavity, or a particular region of the filter material, such as the surrounding area of the tobacco product filter. The additive released into the region may comprise an active ingredient, such as a second additive, which may or may not be supported by the additive release element.

The filter can include a composite filter. The filter may include means for actuating the support structure to indicate that a force should be applied to the filter area. For example, the support structure has a surface that is detectable of any of the layers of the tobacco product packaging, and/or the surface of the tobacco article can include a printed pattern or other visible cues. The support structure within the tobacco product is visible through the window in the filter roll paper and filter paper of the filter.

In some embodiments, the additive release element support structure is located in a composite filter, such as between two sections of filter material. In the three-in-one filter of this example, the filter section includes a mouth end section and a section at the smokable material end of the filter.

In some embodiments, the additive release element support structure can be located at the center of the filter, that is, the two sections of the filter material can be the same size. Alternatively, the support structure can be located away from the center, toward one end or other end of the filter. Even in some embodiments, the filter can be easily in the mouth The end contains a double filter for the support structure and the section of filter material.

In some embodiments, the filter is attached to the rod of the smokable material by means of a filter paper using conventional methods. If opaque filter paper is used, then the filter may include a means of indicating the position of the additive release element support structure, and in order to actuate the support structure, a means of applying a force on the filter area is indicated.

Since the additive release element of the present invention is designed to directionalally release the additive, the directionality of the additive release element inserted into the tobacco product or tobacco product filter should be controllable.

The tobacco product can comprise one or more additive release elements configured to directionalally release an additive to a particular region of the tobacco product or tobacco product filter, which can be any of a tobacco product or a tobacco product filter region.

This region may comprise a material that is active by releasing the additive from the additive release element. For example, the material may comprise a solid that is active in the liquid and is thus active by the action of an additive in the form of water or a particular solvent.

The target area for directional additive release may be a hole in the center of the filter, which may or may not contain other active materials. For example, the pores may contain a flavoring agent that is active when the solvent form additive is directionally released into the pores to contact the crystal. Alternatively, the cavities may comprise materials that are water sensitive to additives in the form of water, for example, materials that contact the water to change color, dissolve, produce sound, emit aroma or odor, and the like.

The specific region designated by the additive may be one of the regions of the filter material containing the solid material uniformly distributed in the material in the form of fine particles. For example, this arrangement is quite useful when granular flavourings are used in conjunction with an additive release element comprising a solvent-containing additive. In this case, a plurality of additive release elements can be used to continuously release the additive throughout the process of use of the tobacco product to provide a flavoring agent. In this setup, the additive can be directed to the same or distinct regions of the particles comprising the filter material.

The area to which the additive is directed may be the surrounding area of the tobacco product or tobacco product filter, such as the area at or near the surrounding surface of the tobacco product, or at the mouth end of the filter. For example, when the additive is colored to provide an interesting appearance of the tobacco product, and/or to provide a visual indication when the additive has been released, for example, the additive release element there contains colored and colorless A combination of additives, this setting is quite suitable. This arrangement is also quite suitable for promoting the diffusion of odors outside the tobacco product when the additive is an odorant.

The tobacco product or tobacco product filter may comprise two or more additives, each of which is loaded into a separate additive release element may be loaded into a similar or separate support structure. For example, this arrangement is quite suitable for chemical reactions of two or more additives, or by oxidation, diffusion or other means of reducing strength over time.

Two or more additive release elements can be configured to release the additive directionally toward each other. For example, this setting is quite useful when the chemical reaction of the additive is used, for example, to carry out an exothermic or endothermic reaction, or to react with an odor or gas, or to have a color or other visible effect.

Two or more additive release elements can be configured to directionalally release the additive toward the common area of the filter. It is quite suitable for a specific area requiring a large amount of additive for supply to the filter, for example, where the additive is water, and a target area of the filter containing the water sensitive material, such as water swellable, water soluble Sex, or water decomposable material.

In some embodiments, the filter comprises a transparent window that allows for visualization of the additive release element support structure and/or additive release element in the filter. In this way, the user can see the additive release element in the filter and can visually determine if the additive has been released.

In some embodiments, the transparent window can be located in the filter roll and/or filter paper. The window can extend around the entire circumference of the tobacco product. It can be limited by the area in which the support structure and the additive release element are placed, and is just visible. Alternatively, the window may be larger such that adjacent portions of the tobacco article, such as the adjacent web of filter material, are at least partially visible.

The support structure can be transparent or translucent or include a transparent or translucent section to allow the user to see the additive release element.

In some embodiments, a relevant portion of the tobacco product, such as a filter, can include means for actuating the support structure to indicate that a force should be applied to the area of the tobacco product. For example, the support structure has a surface that is detectable of any of the layers of the tobacco product packaging, and/or the surface of the tobacco article can include a printed pattern or other visible cues.

To produce the effect of a transparent window, the filter paper may comprise a single piece of transparent material, which may be, but is not limited to, polypropylene, polyvinyl chloride (PVC), cellulose acetate film, polyethylene terephthalate (PET) ), polyethylene oxide (PEOX), polyethylene, cellophane, high barrier film (NatureflexTM), polylactic acid, polylactic acid fiber material, polycaprolactone, polyglycolide, polyhydroxyalkanoate such as polyhydroxybutyl ester, and One of the biodegradable plastics made from zein. The filter paper can have an opaque coating on a particular location to leave a clear uncoated section defining the window.

The filter section may be constructed of individual sections of filter material that are encapsulated in a porous sheet of material. The filter segments and the additive release element support structures are preferably not directly connected to each other, but are only connected by wrapping paper, or even only by filter paper.

1A and 1B show an additive release member support structure 10 according to the first embodiment.

The additive release element 11 is placed in the additive release element support structure 10. In this embodiment, the additive release element is a frangible balloon portion containing an additive.

The additive release element support structure 10 is in the form of a generally hollow cylindrical body. The circumference of the cylinder conforms to or is slightly smaller than the tobacco product filter in the support structure used. Three arm portions 12 projecting into the central cavity of the cylinder. As shown in Fig. 1B, the end of the arm facing the center of the support structure is adapted to receive the capsule portion 11.

The additive release element support structure 10 includes two weakened sections 13 in the surrounding surface. In this embodiment, the weakened sections of the additive release element support structure are constructed by a support structure having a smaller thickness in the areas.

As shown in Figure 2, in the direction of arrow A, in the additive release element The external force exerted on the surrounding surface of the support structure (for example by the user's fingers) causes the support structure to deform. In particular, the deformable section 14 of the additive release element support structure between the two weakened sections 13 is triggered by an external force to bend and assume a concave configuration. The deformable section 14 of the support structure does not include any of the arms 12.

Such deformation reduces the internal volume of the additive release element support structure. Therefore, the bladder portion supported by the arm portion 12 of the support structure is smashed as appropriate.

In the embodiments shown in FIGS. 1A, 1B, and 2, the rupture of the bladder portion 11 is aided by the pointed projections 15 on the inner surface of the deformable section 14. When the deformable section of the additive release element support structure is triggered to deform, the force exerted on the bladder is concentrated in a small area, increasing the ease of rupture of the capsule.

Fig. 3 is an exploded view showing a tobacco product comprising an additive releasing member supporting structure according to the first embodiment. The tobacco product comprises a rod 16 that ignites the suction material, and a filter 17. The filter 17 is a three-in-one filter arrangement in which the support structure 10 is located between the two sections 18 and 19 of the cellulose acetate filter material. The support structure 10 comprises an additive release element 11, which in this case is a frangible pocket. The filter section is combined to form a filter 17 by means of a filter roll paper (not shown) and attached to the rod of smokable material by means of a filter paper (not shown) using conventional methods. Shape 16.

In use, as described above, in the region of the deformable section 14 of the additive release element support structure 10, the deformation of the support structure is induced by the force exerted by the user on the filter 17, and the bladder The rupture of the portion 11. In this manner, the additive is loaded by the bladder portion, which in this embodiment is a flavoring agent (menthol) that is released and entrained in the smoke that is drawn by the user through the filter.

4A and 4B show an additive release member support structure 20 according to the second embodiment.

The additive release element 21 is placed in the additive release element support structure 20. In this embodiment, the additive release element is a frangible balloon portion containing an additive.

The circumference of the additive release element support structure 20 conforms to or is slightly smaller than the tobacco product filter in the support structure used. The support structure 20 has the form of an annular or hollow cylindrical body having a plurality of axial corrugations 22. As shown in this embodiment, the support structure has 8 corrugations. In other embodiments, the support structure can have from 2 to 16 corrugations. For example, the support structure can have 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, or 15 corrugations.

The corrugation is in the form of an axial groove 23 on the outer peripheral surface of the additive release element support structure 20. The corrugations on the inner surface of the support structure have conical ends 24 that project into the central core of the support structure 20.

As shown in Figure 4b, the additive release element 21 can be placed in the center of the additive release element support structure 20. The end 24 of the projection is adapted to receive the additive release element 21. In particular, the distance between the conical ends 24 of the convex portions is greater than the diameter of the bladder portion 21. The bladder is secured in the additive release element support structure by a flange 25 on the projection 24.

The axial corrugations 22 reduce the rigidity of the additive release element support structure 20, particularly for laterally applied forces, either at any Applied to the additive release element support structure in the lateral direction. With regard to this force, such as applied by the user's fingers, the additive release element support structure 20 will change from approximately circular to a more elliptical cross-sectional profile.

The deformable section of the support structure of the second embodiment is not defined in advance as compared with the additive release element support structure of the first embodiment, but is determined by the position of the force applied to the support structure.

The deformation due to externally applied force reduces the distance between at least one pair of protrusions 24 in the opposing projections 24 of the additive release element support structure 20. Therefore, the capsule portion supported between the convex portions 24 is further pulverized. The rupture of the bladder 21 is aided by a projection 24 having a conical end. Therefore, the force exerted on the capsule is concentrated in a small area, which increases the ease of rupture of the capsule.

Figure 5 is an exploded view showing a tobacco product comprising an additive release member support structure according to a second embodiment. The tobacco product comprises a rod 26 that ignites the suction material, and a filter 27. The filter 27 is a three-in-one filter arrangement in which the additive release element support structure 20 is located between the two sections 28 and 29 of the cellulose acetate filter material. The additive release element support structure 20 includes an additive release element 21. The filter section is combined to form a filter 17 by means of a filter roll paper (not shown) and attached to the rod of smokable material by means of a filter paper (not shown) using conventional methods. Shape 26.

In use, as described above, in the region of the additive release member support structure 20, the deformation of the support structure is induced by the force exerted by the user on either side of the filter 17, and the capsule portion 21 rupture. in In this manner, the additive loaded by the bladder is released and entrained in the smoke that is drawn by the user through the filter.

Figures 6A and 6B show an additive release element support structure 30 in accordance with a third embodiment.

The additive release element 31 is placed in the additive release element support structure 30. In this embodiment, the additive release element is a frangible balloon portion containing an additive.

In this embodiment, the cross section of the outer circumference of the additive releasing member support structure 30 is not a complete circular shape but has a circular arc shape or a "C" shape. In other words, in general, the support structure 30 is in the form of a generally hollow cylindrical body that lacks a section of the surrounding surface.

In other respects, the additive release element support structure 30 of the third embodiment is similar to the support structure 10 of the first embodiment. The circumference of the cylinder conforms to or is slightly smaller than the tobacco product filter in the support structure used.

The bladder is adapted to fit into the central cavity of the cylinder and is supported by the bracket 32 and the thickened wall section 33. As shown in Fig. 6B, one end of the bracket 32 is engaged with the thickened wall section 33 to constitute a base adapted to receive the bladder portion 31.

The additive release element support structure 30 includes a weakened section 34 in the surrounding surface. The weakened section 34 separates the section of the support structure of the fixed bladder (including the bracket 32 and the thickened wall section 33) from the deformable section of the additive release element support structure in the form of an articulated arm 35.

In use, the weakened section 34 is hinged or pivoted to create a hinged arm 35 that is movable relative to the section of the additive release element support structure of the fixed bladder Effect.

As shown in Fig. 7, the external force applied on the peripheral surface of the additive releasing member supporting structure (for example, by the user's finger) causes the supporting structure to be deformed, in particular, the hinged arm 35 to weaken the section. 34 is centered towards the displacement of the support structure section of the fixed bladder.

Such deformation of the additive release element support structure reduces the internal volume of the support structure. Therefore, the capsule was shattered.

The rupture of the bladder portion 31 is aided by the pointed projections 36 on the inner surface of the hinged arm 35. When the hinged arm 35 is triggered to turn to the capsule portion 31, the force exerted on the bladder portion is concentrated in a small area, increasing the ease of rupture of the capsule portion.

Figure 8 is an exploded view showing a tobacco product comprising an additive release member support structure according to a third embodiment. The tobacco product comprises a rod 37 that ignites the suction material, and a filter 38. The filter 38 is a three-in-one filter arrangement in which the additive release element support structure 30 is located between the two sections 39 and 40 of the cellulose acetate filter material. The additive release element support structure 30 comprises an additive release element 31, which in this case is a frangible pocket. The filter section is combined to form a filter 38 by means of a filter roll paper (not shown) and attached to the rod of smokable material by means of a filter paper (not shown) using conventional methods. Shape 37.

In use, as described above, in the region of the additive release member support structure 30, the deformation of the support structure and the rupture of the capsule portion 31 are caused by the force exerted by the user on the filter 38. In this way, the additive loaded by the capsule is released and entrained by the user. The smoke sucked from the filter.

The tobacco product filter may comprise two or more additive release element support structures, such as 3, 4, 5 or 6 support structures. In this case, the filter comprises a plurality of support structures, and each of the support structure loaded additive release elements may comprise the same or different additives, and they may be of the same or different sizes.

When multiple additive release element support structures are present in the tobacco product filter, the support structure may require the user to apply the same or different forces for actuation. The user provides this ability to control the extent to which the desired additive is released.

When more than one additive release element support structure is used in a tobacco product filter, the support structure can be of the same design, or a different design. For example, if a different force is required to actuate the additive release element, a different design is used.

Fig. 9 is an exploded view showing the tobacco product according to the fourth embodiment. The tobacco product comprises a rod portion 41 that ignites the suction material, and a filter 42. The filter 42 comprises two configurations of the additive release element support structure 43 as described in the second embodiment above. Each support structure includes an additive release element 44, which in this case is a frangible pocket. In the filter 42, the support structure 43 is located between the two sections 45 and 46 of the cellulose acetate filter material. The filter section is combined to form a filter 42 by a filter roll paper (not shown) and attached to the rod of smokable material by means of a filter paper (not shown) using conventional methods. Shape 41.

In use, as described above, in the region of the additive release element support structure 43, by the force exerted by the user on the filter 42 The deformation of the first support structure 43a and the rupture of the first bladder portion 44a. In the region of the support structure 43, the deformation of the second support structure 43b and the rupture of the second bladder portion 44b are initiated by another force applied on the filter. In this manner, the additive loaded by the bladder is released as needed by a user controllable method and entrained in the smoke drawn by the user through the filter.

Figure 10 shows a tobacco product 50 comprising a cylindrical rod-like portion of a smokable material, in this case a tobacco 51, and a filter 52. The filter 52 is wrapped in a filter roll paper (not shown).

The rod portion 51 of the smokable material is juxtaposed with the filter 52 in such a manner that the end of the tobacco rod portion 51 abuts the end of the filter 52. The rod is wrapped in a wrapper (not shown) and joined to the filter 52 by a filter paper (not shown) using conventional methods.

The filter 52 is a three-in-one filter that includes two substantially cylindrical rolls of filter material 53 and is separated by an additive release element support structure 54 in accordance with a fifth embodiment.

The additive release element 55 is placed in the support structure 54. In this embodiment, the additive release element 55 is a sponge-like material containing an additive. The sponge material covers the surface of the frangible outer casing.

The additive release element support structure 54 is in the form of a generally hollow cylindrical body. The circumference of the cylinder conforms to or is slightly smaller than the tobacco product filter 52. Projecting into the central cavity of the cylinder and dividing the aperture into three equal sectors is the support bracket 56. As shown in FIG. 10, each sector is configured to accommodate the additive release element 55.

The additive release element support structure 54 includes a spike 57 at the center of each of the three sectors in the inner peripheral surface.

The external force exerted on the peripheral surface of the additive release element support structure (e.g., by the user's fingers) causes the support structure to deform. In particular, one or more of the fan-shaped outer surfaces located between the support brackets 56 are forced into a concave configuration.

Such deformation reduces the internal volume of the particular sector of the additive release element support structure 54. Therefore, the additive releasing member 55 held in the sector of the support structure is shredded. Since the spikes 57 are provided, when the support structure is deformed by the trigger, the force applied to the additive release member is concentrated in a small area, which increases the ease of pulverization of the additive release member. When the additive releasing member is pulverized, the fragile outer casing is broken, and the additive is extruded from the sponge-like material into the surrounding filter material 53.

Figure 11A is a cross-sectional view of a tobacco product with an additive release element support structure 60 in accordance with a sixth embodiment.

The additive release element 61 is placed in the additive release element support structure 60. In this embodiment, the additive release element is a frangible balloon portion containing an additive.

In general, the additive release element support structure 60 is the same as that shown in the first embodiment. The only difference is that the present additive release member support structure 60 does not have a deformable section and is not deformed by the application of an external force.

The additive release element support structure 60 is in the form of a generally hollow cylindrical body. The circumference of the cylinder conforms to or is slightly smaller than the tobacco product filter 63 in the support structure used. Highlighting into the central cavity of the cylinder is 3 arms Section 62. Referring to the first embodiment (but not shown in FIG. 11A or FIG. 11B), the end of the arm facing the center of the support structure is adapted to receive the capsule portion 61.

Here, the support structure 10 of the first embodiment includes two weakened sections 13 in the peripheral surface, and as indicated in FIG. 11B, the present support structure 60 has a gap 64. Therefore, the additive release element 61 is not completely enclosed by the support structure 60.

In use, in the direction of arrow B, an external force is applied at the location of the gap 64 on the additive release element support structure 60. The force pushes the additive release member 61 against the arm portion 62 of the support structure 60. Therefore, the bladder portion supported by the arm portion 62 of the support structure is smashed as appropriate.

The rupture of the bladder portion 61 is aided by a pointed projection 65 on the end of the arm portion 62 of the opposing gap 64. Due to the pointed projections, the force exerted on the bladder is concentrated in a small area, increasing the ease of rupture of the capsule.

Figures 12A through 12C show various embodiments in which the support structure is a grooved tubular portion. These figures illustrate the possible shapes of some grooved sections. Fig. 12A is a circular groove shape, Fig. 12B is an angular shape, and Fig. 12C is a square or fortress type.

In some embodiments, the support structures of Figures 4A, 4B, and 12A through 12C can be described as having a plurality of petal-like profiles that engage the petals or leaves. Each petal or leaf contains a radially outward segment and two general radio segments. The radially outward segments have a radially outwardly facing surface that is assembled to contact the inner cylindrical surface of the tobacco product, and a relatively radially inner surface. The radially outward surface has a first end and a second end, each end attached to a radial of one of the generally radiating segments Outward end. As shown, each of the generally radiating segments includes the radially outward end and the radially inward end. The radially inward end of each petal or blade is attached to a radially inward end of the adjacent petal or blade. Therefore, the additive releasing member can be grasped and fixed by slightly expanding radially to achieve the supporting effect.

In some embodiments, the support structure as depicted in Figures 12A through 12C can be fabricated by extrusion and subsequently graduated.

In some embodiments, the support structure can be fabricated by suitable techniques including, for example, blow molding, injection molding, 3D printing, and rotating molds. A combination of various techniques can be used. These techniques are particularly useful for fabricating complex and elaborate structures, such as fabricating the structures depicted in Figures 4A and 4B.

example

In the additive releasing member supporting structure of 5 mm in length accommodating the additive releasing member, a microcapsule portion having a diameter of 3.4 mm was prepared.

A filter having an attachment release member support structure and having a length of 27 mm was prepared, the additive release member support structure being located between two ester cellulose filter sections of length 10 mm and 12 mm.

The filter is then attached to the tobacco rod using conventional means for making standard oversized test cigarettes.

The additive release element support structure is depressed and the additive is released from the microcapsule portion. The pressure difference of the adhesion of the cigarette was measured before and after actuation of the additive release member support structure, and the results are recorded as follows.

Table 1

This result indicates that the pressure differential is substantially unaffected by the actuation of the additive release element support structure.

The required compressive force to actuate the additive release element is measured. As shown in the attached FIGS. 6A, 6B, and 7 , the additive releasing member in the form of a capsule that does not use the additive releasing member supporting structure is pulverized, or as described in the third embodiment above. Typically, the additive release element using the additive release element support structure is shredded. The pulverization strength was measured using a tablet hardness tester manufactured by Schleuniger, and the results are reported in Table 2 below.

This result indicates that the required pulverization strength for rupturing the microcapsule portion is much lower in the case of using the additive releasing member supporting structure than in the case where the additive releasing member supporting structure is not used.

Embodiments of the invention are configured to comply with applicable laws and/or rules, examples and not limitations, such as flavorings, additives, emissions, constituents, and/or related regulations. For example, the present invention can be configured to practice a tobacco product of the present invention, following the release of the additive and following the release of the first additive, following the applicable rules, and still following the release of one or more additional additives. Likewise, in various embodiments, where two or more of the additives react with each other to produce another substance, the resulting material is in accordance with applicable laws/rules.
