Description

capsule

The present invention relates to capsules containing consumable material for water pipes such as hookah devices, particularly capsules suitable for electrically-heated hookah devices.

Prior art The prior art literature on hookah devices is disclosed in WO2015-172224A1. The hookah device includes a capsule (see FIGS. 6 and 7) configured to contain a smoking product. The capsule can be placed within a heating chamber to heat and vaporize a smoking product (eg, a shisha cigarette) therein. The user's inhalation pulls the vaporized product through the water bath and out through the hose.

The capsules may be pre-packaged. For example, manufacturers fill capsules and then sell them to consumers in prefilled form. The inventors have discovered a number of problems with the above prepackaged arrangements.

The smoking product is provided in a single mass. Accordingly, the product contains a low specific surface area (i.e., the amount of surface area per volume of the product). While heating a product, only a small portion of the product may vaporize. This may result in a weaker taste or the formation of a less voluminous haze.

Additionally, a single mass may behave in an unpredictable manner when heated depending on the position/orientation of the single mass relative to the heat source and the air flow through the capsule. Some areas may be significantly hotter or cooler, resulting in a variable experience by the end user. It would be desirable to create a more consistent user experience.

Providing conventional tobacco/molasses with a larger specific surface area typically means that less mass of smoking product is contained within a given internal volume of the capsule. This may result in the capsule contents being consumed more quickly, resulting in the need to replace the capsule more frequently.

Additionally, during the manufacture, transportation, handling and/or storage of prefilled capsules, the product therein may 'set'. This can result in the product agglomerating and/or segregating into components with undesirable or inconsistent properties (e.g., due to the “Brazil-nut effect”). This can lead to sub-optimal performance of the smoking product when heated and thus result in a suboptimal experience for the user.

The object of the present invention is to overcome or improve one or more of the above problems. Providing a capsule that provides a predictable and/or consistent experience to the user may be considered an additional or alternative objective.

According to one aspect of the invention, there is provided a smoking product comprising at least one ingredient configured to vaporize during heating of the smoking product; A housing configured to contain a smoking product and including at least one air path to allow the vaporized ingredients to exit the capsule during use; and a support structure configured to at least partially separate or unfold the smoking product within the housing.

The housing may include one or more flow inlet and/or outlet openings within the capsule. The support structure may define an air path leading to the inlet and/or outlet openings.

Figure 1 shows an example of a water pipe 2, referred to herein as a hookah device, but it will be understood that such a pipe may alternatively be referred to as a shisha pipe. In one embodiment, hookah device 2 is electrically heated and/or electronically controlled.

The hookah device 2 includes a base 4, an electronics compartment 6 and a tank 8 configured to be filled with a liquid coolant (eg water). The device 2 can be supported by a wide base 4.

The electronics compartment 6 includes a lid 12 providing an opening. The electronics compartment 6 is equipped with a heater 10 (shown schematically) configured to receive a capsule 14 containing a smoking product. The heater heats the capsule 14 to vaporize or disperse one or more ingredients of the smoking product. A plurality of holes 16 are provided in the capsule 14 to allow vaporized product to escape from the capsule. The heater can be controlled by electronics within the electronics compartment 6. A power switch 18, etc. may be provided.

The heater is connected to the tank (8) via a conduit (15) passing through the electronics compartment (6). The vaporized smoking product thus passes from conduit 15 through the cooling water of tank 8 and is cooled and/or filtered therein.

A suction hose (20) is provided in communication with a portion of the tank (8) above the coolant level and includes a mouthpiece (22). Therefore, the user can inhale the vaporized product through the device 2 and withdraw it through the hose 20. This system mimics a conventional non-powered shisha/hookah pipe. Air can be drawn through the heated capsule and the vaporized product within the capsule can be transported by airflow through the conduit.

It will be appreciated that the device 2 shown in Figure 1 is merely exemplary and any suitable device may be used. In some embodiments, an electronics compartment 6 may be provided at the bottom of the coolant tank 8 to allow vaporized smoking products to pass through the device 2 when in use. Accordingly, the electronic device storage portion 6 may form the base portion of the device 2 . Conduit 15 extends from the heater and rises into the coolant to allow vaporized products to pass inside the conduit.

Examples of suitable hookahs 2 and associated heaters 10 can be found in previously published patent applications WO 2017/080545 A1 and WO 2015/172224 A1. These details will not be repeated herein for brevity.

2, capsule 14 includes an upper wall 24 and a lower wall 26. The upper wall 24 and lower wall 26 are connected via a side wall 28, for example a continuous side wall. Accordingly, the top, bottom and side walls provide an enclosure/cavity for the smoking product 30.

A plurality of holes 16a, 16b are provided in the upper wall 24 and lower wall 26, respectively. During use, air 32 passes into/through the smoking product 30 through the opening in the upper wall 24. Air 32 entrains the vaporized product 34 within the capsule 14 when heated in use and escapes from a hole in the lower wall 26.

This arrangement provides pre-packaged or pre-filled capsules. Although the apertures 16a, 16b are shown in this example to span the entire width of the upper wall 24 and the lower wall 26, the apertures are preferably located in the upper wall (as shown, for example, in Figure 1). It can be understood that only part of the 24) and/or lower wall 26 may be provided.

The terms “top,” “bottom,” and “side” are used merely to aid in the description of the capsule, and it will be understood that the capsule may be oriented in any suitable orientation for use.

In some embodiments, holes 16 may be provided in only one of the upper wall 24 and lower wall 26. Air therefore enters and exits the capsule through the same hole (16). In some embodiments, a hole 16 may be provided in the side wall 28.

In some embodiments, device 2 is configured to puncture, perforate, or open capsule 14 to allow air to enter or exit. Accordingly, the capsule 14 can be sealed before opening. This can help maintain freshness. The top wall may be perforated by suitable formation of the lid 12 and/or the bottom surface may be perforated by the end of the smoking conduit 15. Therefore, the hole need not be formed at the time of manufacture, but may be formed during use of the capsule.

Capsule 14 may include a seal covering hole 16. The seal is removed before use to reveal the hole 16. Therefore, sealing helps maintain freshness. Seals may be appropriately provided on the top/bottom/side surfaces. The seal may be attached to the capsule 14 using a peelable adhesive or the like.

In some examples, the entire capsule (with or without one or more seals over the holes 16) may be retained in a sealed pouch or sleeve to provide a retail product that can keep the capsule fresh for an extended period of time. The pouch may be filled with a gas (e.g., not air), for example nitrogen. Accordingly, either or both the capsule and the pouch may be filled with a gas to help preserve the smoking product inside until use. The fact is that even if the capsule itself is filled with air, flushing the pouch with an appropriate gas may be sufficient, for example if the gas in the pouch and the air inside the capsule mix over time, lowering the overall oxygen content within the pouch. This was revealed.

Top surface 24 may include a stopper 35 (e.g., a lid). This allows the product 30 to be placed within the capsule 14 . The hole 16a may or may not be provided in the lid 35. The closure 35 is then secured to the capsule (i.e., the upper edge of the side wall(s) 28 of the capsule) to retain the product 30 therein. The stopper may be permanently fixed to the capsule 14 to prevent the product 30 from being removed from inside the capsule. For example, closure 35 may be pressed or attached to capsule 14. The upper edge of the side wall may include a flange for this purpose.

In another embodiment, the closure 35 may be releasably connected to the capsule 14, thereby allowing a user to access the interior of the capsule 14 (i.e., to refill the capsule 14). The closure 35 may be connected to the capsule via a releasable connection means. Releasable connection means include interference fit; snap fit; screw thread; removable latch or clip; clamp; hook and loop; press studs; or bayonet; Or it may include one or more of the similar things.

In this embodiment, the lower surface 26 is formed integrally with the capsule 14 (i.e., formed integrally with the side walls 28). Accordingly, a hole 16b is formed within the capsule 14. In alternative embodiments, lower surface 26 may include a permanent/removable closure.

The capsule 14 in the embodiments of FIGS. 1 to 3 has an upper wall 24 that is wider in plan than the lower wall 26 so that the capsule is formed in a tapered shape. The capsule 14 tapers towards the lower wall 26 . Accordingly, the capsule 14 is trapezoidal in cross-section (from the side).

As shown in Figure 3, capsule 14 includes a circular profile (in plan view). Therefore, the capsule 14 is frustoconical. However, it will be appreciated that the shape of capsule 14 is merely exemplary and that the capsule may include any shape suitable for the intended purpose. Capsules of different shapes may be provided to achieve the desired contact with the interior of the device 2. For example, it is shaped for a close fit and/or good thermal contact with the heater 10. For example, a capsule that is oval or polygonal in plan can be accommodated.

The capsule 14 contains a heat-resistant material. Accordingly, the capsule 14 is stable at the heating temperature of the device 2. The capsule 14 contains a metallic material, for example aluminum. The metallic material ensures proper heat conduction into the capsule. In other embodiments, capsule 14 may include a ceramic material.

The product 30 typically includes a chemically inert filler that does not melt or deteriorate at temperatures equal to or below the temperature at which cigarettes or substitutes thereof are heated within a water-pipe. In this way, the filler is used at temperatures below 250°C; More preferably at a temperature of 300° C. or lower; More preferably at temperatures below 350°C; More preferably, it does not melt/burn/decompose at temperatures below 400°C.

Product 30 includes an absorbent binder. The absorbent binder comprises a powder material. Powder materials contain fine particles. The particles may be finer than those of the inclusion body. Therefore, the absorbent binder contains a high specific surface area. Absorbent binder particles are less than 200㎛; preferably less than 100 μm; More preferably, it may have an average diameter of less than 80㎛. The absorbent binder particles may comprise an average diameter of 2.5 μm to 100 μm; Preferably it is 5㎛ to 60㎛.

Without wishing to be bound by any particular theory, it is believed that absorbent binders stabilize the product by binding the granules to the other ingredients of the product and absorbing liquid that may be present in the ingredients from which the paste is made. This results in the formation of a heat-resistant mixture with no liquid or syrup-like fluid residue, unlike gels, which melt when heated due to their inherently less stable structure.

Absorbent binders include inorganic/mineral materials. The absorbent binder may include silica. The absorbent binder may include 'fumed silica'. Fumed silica includes a powdered material, also known as pyrogenic silica, consisting of primary particles of amorphous silica fused into branched, chain-like, three-dimensional secondary beads, which are then agglomerated into tertiary beads.

The composition of product 30 may provide a paste-like smoking product. Therefore, the product is a semi-solid or highly viscous liquid. The paste can be dispensed into the capsules and allow for simple handling during storage and manufacturing.

Paste exceeds 100Pa·s or 300Pa·s (under standard conditions); Preferably, it may have a viscosity exceeding 500 Pa·s. The paste is between 100 and 3000 Pa·s; Preferably, it may have a viscosity of 500 to 2000 Pa·s.

Unlike conventional gel-based tobacco substitutes, the paste is heat resistant and does not melt or change shape when exposed to temperatures typically encountered inside water-pipes. Therefore, the paste is temperature stable. The paste may not melt when exposed to temperatures below 200°C or 250°C.

These properties make the paste easier to handle and significantly reduce the amount of liquid that may be present during heating. As such, various types of water-pipe heater bowls or capsules can be used. The paste can also be made free or substantially free of combustible materials, thereby preventing the formation of toxic combustion products that typically form from burning combustible materials such as tobacco leaves. Various colorants and flavorings can be included to obtain a variety of pastes to suit all types of consumer preferences.

The specific composition of the paste offers numerous advantages. When heated to a temperature suitable for generating smoke in the water-pipe, the paste does not melt but releases mist-making agents, sweeteners and flavoring agents into the smoke generated in the water-pipe. In some embodiments, the paste releases mist-forming agents, sweeteners and flavoring agents and decomposes into a dry residue rather than melting when exposed to the typical temperatures of a water pipe. If the paste melts or partially melts, this occurs only after the heat-induced release of the mist-forming agent, sweetener and flavoring agent has begun. Without wishing to be bound by any particular theory, it is believed that the absorbent binder stabilizes the paste by binding the granules to the other components of the paste and absorbing liquid that may be present in the ingredients from which the paste is made. This results in the formation of a heat-resistant mixture that is generally free of liquid or syrup-like fluid residues. This is in contrast to gels, which melt when heated because they have an inherently less stable structure.

In a second aspect, a method of manufacturing capsules containing such paste smoking products for delivery to consumers is provided. The ingredients of the paste, including granules of inert material, absorbent-binder, sweeteners and flavors, are mixed together and then distributed into capsules using support structures of the type described herein to provide a consistent shape/form of the paste.

In one embodiment, the ingredients are mixed together at room temperature, but mild heating may be applied if it aids better or faster mixing. Excessive amounts of solvent, which may make the paste wet or feel syrupy to the touch, can be removed by standard methods, such as exposure to a stream of air. Advantageously, the paste can be stored in soft, flexible packaging and dispensing pumps for more convenient, less messy and easier set-up than conventional gels.

Examples of pastes are:

At room temperature, the ingredients were mixed in relative amounts within the following range to form a plurality of pastes.

ingredient Content (wt%) High-fructose corn syrup 20-25% coloring agent 0.01-0.02% glycerin 50-55% Spices 1-10% fumed silica 5-10% silica sand 7-10% additive 0.2-0.4%

The glycerin in the paste had a specific gravity of 1.2612 g/ml, a maximum moisture content of 0.3%, and a minimum glycerin content of 99.7% at 25°C. The fumed silica was characterized as having a pH of 3.8 to 4.3, a BET surface area of 175-225 m2/g, and a tap density of 60 g/L. The high-fructose corn syrup was characterized as having a pH of 3.3 to 4.5, an acidity of up to 4 ml, a dry matter content of 76.8 to 77.4%, and a refractive index of 1.4774 to 1.4798 at 20°C. The color of fructose received a maximum score of 20 points in the ICUMSA (International Committee for Uniform Analysis of Sugars) grading system. The fructose content of the aqueous solution was measured between 74.80 and 75.80 in Brix (°Bx).

A sample of each paste was tested by heating it in a water-pipe to a temperature of approximately 300°C. In all cases, the paste retained its shape and did not melt when heated, and when inhaled, it released an aerosol containing fructose, glycerin, and flavoring.

Next, a sample of one of the pastes was analyzed by rotational viscometry on a rheometer. The composition of the tested paste was as follows:

Composition of the tested paste ingredient wt% fruit sugar 25% coloring agent 0.015% glycerin 52.3% Spices 5% Fumed Silica 9% silica sand 8.5% additive 0.2%

First, the rheometer was verified using ASTM N15000 oil (41.1°C), which was selected as a standard because it had a similar viscosity to the sample. On the day of analysis, the instrument setup was successfully validated using standard oil and 25 mm plate-plate geometry, which deviated by less than 4% from the certified viscosity of the standard oil.

The viscosity of the paste samples was measured during a shear rate sweep performed at 25.0°C on a 25 mm plate-plate geometry with 1 mm spacing. The shear ramps included shear rates of 10, 18.8, 32.6, 56.9, and 100 s ^-1 , respectively. The analysis was completed in duplicate, and the results are as follows.

Shear rate (s ^-1 ) Viscosity (Pa·s)1 Viscosity (Pa·s)2 Viscosity (Pa·s) 10.00 908.58 855.17 881.88 18.80 300.30 330.66 315.48 32.60 158.18 173.03 165.60 56.90 84.10 99.85 91.98 100.00 50.67 52.57 51.62

The sample is a shear-thinning and non-Newtonian fluid. These properties help the paste flow more easily during application but remain in place once applied.

Product 30 is substantially free of tobacco and/or nicotine. Accordingly, product 30 may provide a healthier alternative to conventional products.

In some embodiments, product 30 includes a product containing nicotine (or a derivative thereof). The product 30 may include tobacco. The product may include a tobacco substitute (e.g., an organic substrate).

In some embodiments, product 30 may include a conventional shisha or tobacco product (eg, shisha or moiselle). Product 30 may include a tobacco product containing sugar syrup (e.g., molasses). Product 30 may include glycerol or other mist-forming agent. Products may contain fragrances and/or other additives. Accordingly, the product may include a mixture of solid and liquid ingredients, for example, a mixture of tobacco or other plant-based smoking product with any of the other ingredients described above to provide a smoking product as a wet mass.

Capsule 14 includes an internal structure for the smoking product, referred to herein as a separator or support structure, configured to at least partially divide, separate, space or maintain a desired surface area of the smoking product. The separator may help control the dispersion/uniformity of the smoking product within the capsule and/or divide the product into a plurality of portions that are at least partially spaced apart or separated. This may provide one or more of many possible advantages.

- Prevents the product from settling into a single mass, for example during handling or transport

- By increasing the specific surface area of the product, the quantity/quality of smoke generated during use increases.

- Adjusting the surface area to volume ratio for the product within the capsule to enable the user to achieve the desired strength and/or longevity when applying a heating regime by electric heaters

- Provides an air path into/through the product to increase contact with the product.

In some embodiments, the support structure may confine the smoking product to only a portion of the capsule interior. The support structure may partially fill the capsule, for example filling the top and/or bottom of the interior of the capsule. The support structure may define air path(s), for example, to ensure adequate airflow and/or pressure drop through the capsule during use.

In some embodiments, the separator/support structure includes breathable members or spaced apart elements that form air passages therebetween. The air permeable properties of the support structure can provide separation of the product and increase airflow within the capsule. This arrangement may be advantageous when the product 30 comprises a liquid or semi-liquid (e.g., a paste) and the breathable member acts as a substrate to distribute and/or separate the product 30.

In some embodiments, the breathable member includes mesh. The mesh may be woven or non-woven. The mesh may be metallic. The metallic mesh may include food safe metals. The mesh may be comprised of a fine mesh (e.g., <1 mm) to prevent particulates from passing through. Alternatively, the mesh may include a coarse mesh (eg, >1 mm) to increase flow through capsule 14.

In some embodiments, the breathable member includes foam. Foams may include porous and/or open cell foams. The foam may include high temperature (e.g., greater than 200° C.) resistant materials. Foams include inorganic foams, such as porous glass (eg, pumice); porous ceramic; and porous minerals (e.g., zeolites).

Foam may include rigid/rigid materials. In alternative embodiments, the foam may be flexible or deformable/flexible.

In some embodiments, the breathable member may include a paper-based material. The paper-based material may include parchment paper or baking paper. The paper-based material may include card or cardboard.

Breathability may be provided by the inherent properties of the breathable member material (eg, mesh or foam). Alternatively, if the breathable member material is impermeable or has low permeability (eg, paper), openings, channels, recesses, etc. may be provided to increase breathability. For example, a paper-based material can include a plurality of perforations (eg, arranged in an array).

In some embodiments, the permeability of inherently breathable materials may be enhanced/modified by providing openings, channels, recesses, etc.

The breathable member may be configured to burn, decompose, or deteriorate while heating the capsule. This may increase air flow or product flow during use of the capsule. Alternatively, the breathable member may not deteriorate with use and may remain substantially intact after use.

A first example of a breathable/porous member 36 is shown in Figure 4A. In a specific example, breathable member 36 includes mesh. Breathable member 36 extends along the bottom surface 26 and side walls 28 of capsule 14. Accordingly, the breathable member 36 provides a bowl or basket-like arrangement. Breathable member 36 may substantially conform to the shape of capsule 14 (i.e., extend the overall height/width of capsule 14).

Product 30 may simply be seated on breathable member 36. If the product 30 includes a more liquid or semi-solid composition, the product may spread over at least a portion of the breathable member 36. Accordingly, product 30 may at least partially cover and/or penetrate the breathable member (e.g., fill gaps in the mesh).

Breathable member 36 may remain loosely within capsule 14. Movement of the breathable member 36 can be prevented by close contact with the capsule wall. Alternatively, the breathable member 36 is secured in place.

In some embodiments, the lower portion of breathable member 36 may be absent. Accordingly, the breathable member 36 may include a frustoconical ring.

Capsule 14 includes a partition 38 configured to divide product 30 into separations 30a, 30b and/or increase surface area. The partition wall 38 extends from the lower surface 26 toward the upper surface 24 therebetween. The partition wall 38 may extend substantially the entire height of the capsule 14. Accordingly, the product 30 is divided into individual parts 30a and 30b. Accordingly, the partition may provide a baffle or similar.

The breathable member 36 and/or partition wall 38 comprises a substantial thickness. Accordingly, the breathable member 36 and/or partition wall 38 may provide a fluid passageway through/into the product to increase airflow within the capsule 14.

Referring to Figure 4b, an alternative is shown in which the support structure defines a central flow path 37 penetrating the interior of the capsule, for example extending towards the flow outlet of the capsule or between the inlet and outlet. The support structure may define an enclosure for the smoking product that is annular. In this example, partition 38A may itself be annular, separating the central flow path from an external space for, for example, smoking products. The septum 38A may or may not be porous in this embodiment, as no flow is required to pass through the support structure walls and the desired flow through the capsule is ensured by the channels 37. The base of the support structure may or may not be present together with a partition formed, for example, by the shaped inner wall of the capsule. In this way, it may be integrated with the side walls and the bottom partition of the capsule, for example, it may be integrated with the partition 38A that forms an extension of the base/bottom of the capsule.

In the example of Figure 4B, septum 38A terminates at a distance below the upper surface 24 of the capsule. This allows room for air to enter the capsule and mix with the gases/vapors within the capsule before exiting the capsule through the flow passage 37.

In various embodiments, capsule 14 may include a plurality of partition walls. In the specific example shown in FIGS. 5A and 5B , a plurality of partitions 38 are provided to define a plurality of compartments 40a-f to contain respective products 30 therein.

The partition 38 extends in a radial direction (ie, from the center point in Figure 5A). Accordingly, the partition wall 38 provides a spoke-like arrangement. Therefore, a partition contains a sector type. Any number of partitions 38 may be provided to divide the capsule 14 into any number of sectors. For example, 1-10 partitions may be provided to provide 2-10 sectors accordingly. The septum can help prevent the smoking product within the capsule from becoming a single lump within the capsule.

In the example of Figure 5b, the radial septum 38 terminates in an annular septum 38A that defines a flow path 37 through the capsule.

A third example of a support structure or breathable member 36 is shown in FIG. 6 . In this example, the partition walls 38 are provided in a parallel arrangement. Accordingly, the partition wall 38 defines a plurality of elongated sections 40. The partition walls 38 may be evenly spaced apart. In another embodiment, the spacing of partitions 38 may be such that each compartment 40 contains the same volume.

A fourth example is shown in Figure 7. In this example, the partition walls 38 are arranged in a grid. Accordingly, the partition wall 38 defines a plurality of cells 42 . The number of partition walls 38 in one direction (eg, left/right) may be different from the number of partition walls 38 in a second orthogonal direction (eg, top/bottom of the page). This can provide elongated cells. In another embodiment, cells 42 may be divided evenly (eg, to provide square cells or cells of more uniform area).

In some embodiments, cells 42 may be substantially the same shape/size. For example, as shown in Figure 8, cells 42 may be arranged in a hexagonal arrangement. Accordingly, each cell 42 may include a hexagonal shape.

In some embodiments, cells 42 may include different shapes/sizes. For example, as shown in Figure 9, the cells include triangular cells 42a and segment cells 42b.

In some embodiments, cells 42 may include random and/or irregular shapes.

In some embodiments, the septum 38 may extend only partially across the capsule (i.e., only partially between the side walls 28 of the capsule). Accordingly, the partition 38 can only partially divide the smoking product 30 . For example, as shown in Figure 10, a plurality of partition walls 38 extend radially inward from the capsule side wall 28. The septum thus provides a crosshair like array. The central partition 38A may or may not be provided in different embodiments.

In some embodiments, the partitions or support members may be arranged in a formation/pattern with rotational symmetry about the axis/center of the capsule.

In some embodiments, partial partition 38 may be spaced apart from sidewall 28. In some embodiments, a plurality of partial partitions 38 may be connected. For example, the plurality of partition walls 38 may provide an X-shaped partition distal from the side wall 28 (eg, at the center of the capsule 14).

In some embodiments, the partition(s) 38 may only partially extend in the height direction of the capsule 14 (i.e., may only extend partially between the upper surface 24 and the lower surface 26). . As shown in FIG. 11, the partition wall 38 does not extend the entire distance to the upper surface 24 and the lower surface 24. Accordingly, the partition wall 38 can be directly fixed to the capsule wall 28. Accordingly, respective gaps 44 are provided between the partition wall and the upper/lower surfaces. This arrangement may be advantageous when some diffusion of product 30 is desired during smoking (e.g., when product 30 is liquid/semi-solid).

In FIG. 9, a gap 44 is provided between the partition wall 36 and the upper/lower surface, but the gap 44 may be provided only between the partition wall 36 and either the upper surface 24 or the lower surface 26. Able to know. The gap from the top or bottom of the capsule top 24 and/or bottom 26 may provide a plenum/manifold area for mixing of gases/vapors when in use.

In some embodiments, the septum 38 may only partially extend the height of the capsule 14 at selected portions. Accordingly, the gaps 44 may be provided as one or more separate parts. This arrangement can provide a 'window' through which a selected amount of product flows within the capsule 14. The gaps 44 may be provided adjacent to and/or spaced apart from the top/bottom surface.

In some embodiments, partitions 38, 38A may be air impermeable (i.e., continuous) in shape. Accordingly, the partition walls 38 serve to divide the product 30 into separate parts. The impermeable partition walls 38 may be arranged in substantially the same manner as the permeable partition walls described herein.

The impermeable partition walls 38 may be formed integrally with the capsule 14. This may be advantageous if the capsule 14 comprises a moldable material (eg, plastic, etc.) or a malleable material (eg, aluminum or another metal).

In other embodiments, impermeable partition 38 may include individual members. The impermeable septum 38 may be secured to the capsule using any suitable technique (eg, welding or adhesive). In some embodiments, partitions 36, 46 may be retained within capsule 14 by an interference fit or a tight/friction fit. 4 to 10, the partition walls may be provided by an insert member 36 or may be attached to the wall(s) of the capsule as a structural component of the capsule body.

In some embodiments, the impermeable septum 38 may remain loosely within the capsule 14, but tight contact with the capsule 14/product 30 ensures that the septum 38 remains in place. The partition wall 38 may be removable. The partition wall 38 may be removed before or after use for recycling or refilling. The partition wall 38 is attached to a lid, etc. and can be conveniently removed. If the insert 36 is removable or loosely inserted inside the capsule, it can be said to be basket-like inert to the capsule.

As shown in Figure 12, breathable member 36 may extend across the capsule (i.e., between side walls 28). In certain embodiments, breathable member 38 includes foam, gauze, wool-like material, or similar materials. The product 30 is seated on top of the breathable member 36. Additional breathable members 38 may then be placed on top of product 30. Accordingly, the product 30 has a plurality of breathable members 36 and 38 interposed therebetween. The above process is repeated to provide a layered arrangement. The layered arrangement alternates between the product 30 and the breathable member 38 (e.g., forming a lasagna-like arrangement). The layers may be substantially parallel.

The layer may be parallel to the upper surface 24 and/or the lower surface 26. Accordingly, air can pass through the layers 36 vertically.

The uppermost and/or lowermost portions of the layered arrangement include a breathable member 36. This can prevent product from leaking from the capsule 14.

13 , in some embodiments of a layered arrangement, product 30 may be supported on carrier 46. The carrier 46 is then seated/supported on the breathable member 38. This arrangement can provide many advantages.

- Can assist in inserting product into capsule 14 during manufacturing

- Separating the product to increase its surface area and/or prevent settling.

- Prevents crushing of the product by the above layers

Carrier 46 includes a corrugated/corrugated sheet. The wavy shape thus defines a plurality of compartments for the product 30 . Accordingly, the carrier 46 divides the product 30. In certain examples, the carrier includes a paper-based material.

In some embodiments, carrier 46 may include a tray-like arrangement (i.e., comprising a base portion and side walls). Therefore, the product can be contained in the tray. The tray may include one or more partition walls to divide the tray into a plurality of compartments.

In some embodiments, carrier 46 may comprise a plate or sheet-like arrangement (i.e., is substantially flat).

In some embodiments, one or more layers of product 30 may be separated by spacers. Spacers may include columns, pedestals, spikes, columns, tables, or the like. Products 30 may be provided in a tiered arrangement.

As shown in FIG. 14 , breathable member 36 may include flexible sheet 48 . Flexible sheet 48 may include a plurality of perforations 50, etc. to allow air flow. Flexible sheet 48 may include elongated strips. Product 30 is placed on flexible sheet 48 . Flexible sheet 48 is shaped to provide a separator/support for the product.

Perforation is 0.2mm to 5mm; Preferably, 0.2mm to 2mm; Preferably, 0.2mm to 1mm; Preferably, it may include a size (e.g. diameter/width) of 0.5 mm to 1 mm. perforation greater than 0.2 mm; Preferably, it may include a size of 0.5 mm or more. perforation less than 5 mm; Preferably, it may include a size of 2 mm or less. perforation greater than 5 mm; Preferably, an interval of 100 mm or more may be provided.

The product may be placed in a linear fashion on flexible sheet 28 (shown in Figure 15). In some embodiments, the product may be provided in a wave shape (eg, zigzag) across the surface of flexible sheet 28.

In some embodiments, product 20 may be provided in a layer across a portion or entire surface of flexible sheet 28. Accordingly, product 30 may be provided with a coating or partial coating. The coating may be provided on one or both sides of flexible sheet 28. In an example, if the product 20 is applied in a layer or partial layer, the product may have a layer depth of 1 to 10 mm, for example 1 to 5 mm.

A first embodiment of a flexible sheet arrangement is shown in Figure 15. Flexible sheet 48 is wound around itself to provide a spiral shape. The product 30 thus forms a helix (i.e. forms a concentric spiral) accordingly. This arrangement provides a “Swiss Roll” type arrangement. The helical array is then placed into the capsule 14. The spiral arrangement is arranged so that the side edges 52 of the sheets face the upper and lower surfaces 24 and 26 of the capsule 14, respectively. This allows air to flow across the flexible sheet 48 when in use.

15, the flexible sheet 48 is loosely wound to provide gaps 54 between the wrap layers. The gaps 54 can improve air flow through them. In other embodiments, flexible sheet 38 may be tightly wound such that adjacent layers are in contact with each other.

Although a single helix arrangement is shown, it will be appreciated that any number of individual helices may be provided.

In some embodiments, flexible sheet 48 is configured to at least partially encapsulate the product to provide individual parcels or the like.

A first embodiment is shown in Figure 16. Flexible sheet 48 includes a hollow cylinder. Product 30 is provided in a hollow cylinder. This arrangement forms a pellet or 'cannoli'-like arrangement. The cylinder includes an open end 56 to partially enclose the product and allow air flow.

A plurality of pellets are provided within each capsule 14. Accordingly, the cylindrical sheet acts as a separator for the individual parts of the product 30.

In some embodiments, flexible sheet 48 may include a conical shape. The product 48 is placed within the cone interior, providing a 'cream horn' like arrangement.

A second embodiment is shown in Figures 17 and 18. As shown in Figure 18, the product 30 is comprised of two portions of flexible sheets 48a and 48b. The portions 48a, 48b are sealed at each edge 58 to form a bag 60 or the like. The product 30 is fully encapsulated, providing a 'ravioli'-like arrangement. The capsule 14 may be provided with a plurality of bags. Air gaps naturally form between the bags to provide airflow.

Flexible sheets 48a, 48b may include provision for depth of product 30. For example, one or both sheets 48a, 48b may include a recess 62 or pocket for receiving product 30. In other embodiments, product 30 is accommodated by the flexibility/conformability or folding of sheet 48.

In some embodiments, sheet portions 48a, 48b are formed from separate sheets 48. Sheets 48a, 48b are then integrated to encapsulate product 30. A plurality of product portions may be provided in a spaced apart arrangement on the sheet 48a. The second sheet 48b can be laminated on the first sheet 48a to encapsulate a plurality of products. You can then cut between the sections to form individual bags.

In other embodiments, sheet portions 48a, 48b may be formed from a single piece of material (i.e., by folding over it). It will be appreciated that this arrangement can be used to provide a plurality of products as described herein.

Although the bag 60 shown in FIG. 18 includes a rectangular/cubic shape, it will be appreciated that the bag 60 may include any suitable shape. For example, the bag 60 may be circular/spherical/cylindrical; or triangular/pyramidal (eg, tetrahedral).

In one embodiment, product 30 is enclosed within casing 62 to form a “sausage”-like arrangement. As shown in Figure 19, casing 62 completely surrounds or packages the product. Therefore, the casing 62 acts as a separator.

As shown in Figure 20, the surrounded products 30 are elongated. For example, the enveloping product has a length:width ratio greater than 5, preferably greater than 10. This arrangement increases its surface area. Casing 62 may include a seal 64 at one or both ends thereof. Sealing 64 can be, for example, heat sealing; glue; lashing; or may be provided by any suitable means using a locking device. In some embodiments, the ends of casing 62 may remain open.

Casing 62 is flexible. The enclosed product may be rolled up or otherwise deformed to fit inside the capsule. Flexibility of the casing 62 may be provided by the thinness or elasticity/compliance of the casing 62. As shown in Figure 20, a plurality of fully enclosed products 30 are provided within a single capsule. Products under siege.

In some embodiments, casing 62 includes mesh. In some embodiments, casing 62 includes an air or liquid permeable member.

In some embodiments, capsule 14 includes an impact member. The impact member extends inside the product 30 to help reduce flow of the product 30 due to collisions on the impact member.

A first example is shown in Figure 21. Impact member 64 includes a plurality of “fingers” 66. Fingers 66 include elongated rods or pins or the like. The fingers 50 are parallel to each other. Fingers 66 are mounted on base 68. As shown in Figure 23, fingers 66 are spaced relative to base 68 (i.e., approximately a 2D plane). Accordingly, the fingers 66 extend throughout the product 30 .

The fingers 66 include a circular cross-section. However, fingers 66 may be of any suitable shape, for example, triangular; Rectangle; Or you can take a hexagon. Fingers 66 may be solid or hollow.

The fingers 66 are arranged in a hexagonal arrangement. This provides an even distribution of fingers 66. Again, this arrangement is merely exemplary and the fingers 66 may be arranged in any suitable arrangement, for example a rectangular arrangement; Or, you can see that they can be spaced out randomly.

In some embodiments, fingers 66 may be provided only on selected portions of capsule 14/product 30. This may be provided where only certain portions of the product 30 are prone to settling. In some embodiments, the size and/or spacing of fingers 66 may vary across capsule 14.

The collision member 64 is configured to be detachable from the capsule 14. Accordingly, as fingers 66 are withdrawn within product 30, channels may remain therein. This may increase airflow within capsule 14. Fingers 66 are shaped/sized/spaced to be inserted into holes in the upper surface 24 and/or lower surface 26. Accordingly, when the impact member 64 is removed, holes in the upper surface 24 and/or lower surface 26 are exposed.

Base portion 68 is sealed against upper surface 24 and/or lower surface 26.

Accordingly, impact member 64 may provide a lid/seal for capsule 14. This ensures that the product 30 remains fresh. Base portion 14 may be sealed to the capsule using any suitable means, such as an adhesive.

Impact member 64 may include a handle 70 to aid removal from capsule 14. In other embodiments, use may simply point the edge of the base 68 away from the capsule. Alternatively, a pull-tab, etc. may be provided.

In some embodiments, one or more of the fingers 66 includes a stirrer 72 thereon. Accordingly, as the fingers 66 are withdrawn, the agitator 72 engages and redistributes/disturbs the product 30.

In the first example shown in Figure 21, the stirrer 72a includes a flange or the like. The flange may include a substantially flat plate. In a second example, agitator 72b includes barbs (eg, chevron or arrowhead shaped). A stirrer 72 may be provided at the end of the finger 66. Accordingly, the stirrer 72 can travel the entire height of the capsule 14 during withdrawal of the fingers 66 . In some embodiments, a plurality of stirrers 72 may be provided on each finger 66.

In an alternative embodiment, the impact member 64/fingers 66 may be fixed to the capsule (i.e., not removable).

A second example of a collision member is shown in Figure 23. In this example, fingers 66 are substantially hollow. Fingers 66 are aligned with holes in top surface 24. Accordingly, fingers 66 provide a path for air into/through capsule 14 and/or product 30 (e.g., a chimney or flue-like arrangement). Accordingly, the air path is similar to the flow path 37 of FIGS. 4B and 5B discussed above. This arrangement thus provides collision and improves airflow.

Fingers 66 are substantially D-shaped/semicircular. In alternative embodiments, fingers 66 may take any suitable form.

A first example of fingers 66a is shown on the left side of FIG. 24 . In this example, fingers 66a extend only a portion between upper and lower surfaces 24 and 26. Accordingly, the ends 74 of the fingers 66a remain within the product 30 when in use.

The fingers 66a have a sufficient size to prevent the product from entering the interior of the fingers 66a.

A second example of fingers 66b is shown on the right side of Figure 24. In this embodiment, the fingers 66b extend the entire length between the upper surface 24 and the lower surface 26. Fingers 56b include a breathable surface (eg, provided by perforations/mesh). The perforations/mesh are sized to fit product 30 into fingers 66b. Accordingly, fingers 66b provide an air path extending through product 30.

In some embodiments, article 30 is provided on a porous/permeable or substantially air-impermeable substrate. The substrate comprises an inert or food safe material. Inert materials are constructed so that they do not melt, burn, decompose, or otherwise deteriorate when exposed to heat. For example, the inert material is temperature stable to at least 200°C, at least 300°C, or at least 350°C. Inert materials may include either “inert filler” materials or “components” as described above. In certain embodiments, the substrate is stone; glass; ceramic; Contains pumice or sand.

A first embodiment of the substrate is shown in Figure 26. Product 30 is provided on the surface of substrate 76 . Accordingly, product 30 provides a coating on substrate 76. Substrate 76 provides the core. Coating 30 covers substantially the entire surface of substrate 76, thus maximizing the surface area of article 30. Coating 30 may comprise a uniform thickness across the surface of substrate 76 . In alternative embodiments, coating 30 may only partially cover the surface of substrate 76 and/or the thickness of coating 30 may vary.

Coating 30 may include the same composition as the “paste” described above. The absorbent binder can help bond the coating 30 to the substrate 76.

In some embodiments, coating 30 may not include particulate inert filler material.

In some embodiments, coating 30 may include a thickener. Thickeners may include gel formers. Gel-forming agents are capable of forming gels in aqueous mixtures at room temperature. Thickeners can increase the viscosity of the coating layer to provide a shiny appearance. The thickener may include one or more polysaccharides (e.g., starch, gum, or pectin). The starch is arrowroot; corn starch; katakuri starch; potato starch; accident; tapioca; Or it may include one or more of its derivatives. Gums include microbial and/or vegetable gums such as alginate; guar gum; locust bean gum; gum arabic; Or it may contain one or more of xanthan gum. Thickeners include protein thickeners such as collagen; egg white; or gelatin. Thickeners include, for example, agar; carboxymethyl cellulose; pectin; Or it may include one or more of carrageenan.

As described herein, it can be appreciated that the composition of coating 30 may be used in any of the embodiments. Conversely, the paste composition may be used to coat the substrate 76. For clarity, the coating 30 and/or paste may include an inert filler; absorbent binder; mist-preparation agent; sweetener; Spices; or any suitable combination of thickeners.

Substrate 76 includes a round/spherical shape. Accordingly, product 30 and substrate 76 define an arrangement such as beads 78 . However, it will be appreciated that the substrate 78 may include any suitable shape, for example, a rectangular parallelepiped or pyramid shape. In some embodiments, substrate 76 may include a plate, disk, or puck-like shape. In some embodiments, substrate 76 may include an elongated rod or lozenge shape. In some embodiments, substrate 76 includes an oval shape. In some embodiments, substrate 76 may include a ring (ie, donut or toroidal) shape. In some embodiments, substrate 76 includes one or more of the above shapes.

The substrate/core 76 has an average diameter of 0.5 mm to 20 mm; preferably 1 mm to 15 mm; More preferably 2 mm to 15 mm; More preferably 2 mm to 10 mm; And most preferably, it may include 3 mm to 10 mm.

Substrate 76 contains more than 30 wt% of the weight of bead 78; Preferably it may contain more than 40wt%. Substrate 76 is comprised of 30 wt% to 70 wt% of the weight of bead 78; Preferably, it may contain 40wt% to 60wt%.

Beads 78 may include about 1.5-2 wt% thickener, about 6-9 wt% mist-making agent, about 14-18 wt% carbohydrate sweetener, about 2-5 wt% flavor, and about 0.0 wt% colorant. If the coating is formed from an aqueous mixture of ingredients, the amount of water in the coating is about 6-8 wt% of the total weight of the capsule.

The composition can provide a “dry” product. Accordingly, the coating 30 is not sticky or syrupy, ensuring that the beads 78 do not stick to each other. Coating 30 may be smooth (eg, the coating provides a smooth shell). Beads 78 are free to move within capsule 14. Beads 78 may be easy to handle by the user or while filling capsule 14.

A method of making beads 78 includes forming a coating mixture containing a fragrance and applying it to a core bead to form a coating layer precursor. An absorbent-binder is then added, converting the precursor into a coating layer that encapsulates the core beads.

The coating mixture is created by first dissolving or suspending ingredients including flavoring agents, mist-making agents, sweeteners, and thickening agents in a solvent. In some embodiments, one or more ingredients, such as fragrances, may be introduced at a later stage of the process rather than as a component of the coating mixture. The selection of an appropriate solvent depends, inter alia, on the need for the solvent to form a homogeneous mixture with appropriate viscosity and other desired properties when combined with other components. In some embodiments, the solvent is water alone or in combination with aqueous soluble solvents such as methanol, ethanol, isopropanol, glycol ether solvents, and combinations thereof.

The coating mixture may also contain additives such as colorants and stimulants. Certain additives may be used to help disperse other components in the solvent, among other purposes.

Once ready, the coating mixture is applied to the core bead. In one exemplary embodiment, a batch of core beads is placed in a pan of a spray coating machine that is configured to rotate in an orbital manner. The rotating motion causes the beads to tumble within the pan. During the orbital tumbling motion of the beads, a coating mixture is added to form a coating layer precursor on the surface of the beads. The coating mixture can be introduced by spraying, which can produce a faster and more even distribution than simply introducing it as a liquid.

Once a sufficient amount of coating mixture has been added, the absorbent-binder is introduced. If the absorbent-binder is a powdery material, it may be supplied to the coater while the fan rotates, causing dust of the absorbent-binder on the beads. The rotation may be prolonged until the applied absorbent-binder is evenly distributed and the particles are covered with a uniform coating, after which the beads evaporate at least a portion of the solvent present in the coating layer precursor, for example by flowing air in a fan. It dries to create beads that are dry and smooth to the touch, with no liquid or sticky residue on the surface. If desired, one or more ingredients, for example perfumes, may be added to the coating at this stage rather than as component(s) of the coating mixture.

In some instances, it may prove advantageous to split the coating mixture into two or more parts. The first portion is combined with the absorbent-binder on the bead surface as described above to form the first layer of the encapsulation layer.

Then, the second portion is applied to form a second layer overlapping the first layer. The process may be to apply one additional portion until the encapsulation layer achieves the desired thickness.

In this embodiment, substrate 76 includes a substantially smooth surface 80. In some embodiments, surface 80 may be roughened. This may improve bonding with the coating 70. In some embodiments, surface 80 may be wavy/complex to increase the surface area of substrate 76.

While specific examples of coatings suitable for substrates (eg, beads/elements) are described above, the coating may include only some of the coating materials described above. For example, the coating may include a flavor coating and the capsule may contain other types of smoking materials in addition to the coating.

As shown in FIG. 26, the capsule 14 is provided with a plurality of beads 78. The stack of beads provides gaps 82 between them. Accordingly, the bead arrangement provides an air path and assists in dispensing the product 30. Capsule 14 may be partially filled to provide free space 84 within the capsule. The beads 78 are loosely held within the capsule (i.e., they are free to flow). This may allow the user to shake the capsule 14 before use to help disperse the beads 78. Beads 78 are less than 80% of the capsule's internal volume; preferably 70% or less; More preferably, it may account for 60% or less.

In some embodiments, the plurality of beads 78 may include different sizes (eg, different diameters or volumes). For example, at least one bead 78 has a first size, at least one bead 78 includes a second, different size, etc.

In some embodiments, the different bead 78 sizes are selected from a finite set of individual sizes (i.e., from a list of predetermined sizes). For example, a first set of beads may include a diameter of 1 mm, a second set of beads of 2 mm, and a third set of beads of 3 mm. An example of this distribution is shown in Figure 27. Individual/quantized bead sizes therefore produce multiple individual peaks 86 in the distribution curve.

The number of beads 78 (i.e., individual bead size) in each peak 86 can vary between different individual bead sizes (i.e., producing different peak 86 heights). In an alternative embodiment, the number of beads 78 within each peak 86 may remain substantially constant. Accordingly, the bead size distribution can be substantially uniform.

In an alternative embodiment, the different bead 78 sizes are distributed continuously. Accordingly, as shown in FIG. 28, the bead size may include a continuous distribution curve 88. The bead size can fall within a predetermined size range 90.

The number of beads may vary depending on the bead size distribution, thus producing a non-uniform curve 88a. In some embodiments, the bead size distribution may include a Poisson, normal, or Weibull distribution. The number of beads may increase toward the center of the bead size distribution.

In some embodiments, the size distribution includes a substantially uniform curve 88b (the number of beads 78 of each different size is the same). This can be achieved by providing random bead sizes.

It will be appreciated that the graphs shown in FIGS. 27 and 28 are illustrative only and are helpful in explaining the present disclosure.

The distribution of bead 78 sizes can be adjusted to create optimal smoking conditions. For example, a smaller bead size will create more surface area of the product 30, thus increasing smoking intensity (i.e., density of volatile product). However, this will increase the rate of product depletion, leading to low-strength products heading toward end-of-use. Additionally, small bead sizes provide low thermal inertia, reducing the time it takes for the beads to reach the temperature required for the coating to become volatile. Therefore, small beads act quickly.

Conversely, larger beads will provide a lower intensity smoke, but will have a reduced depletion rate compared to smaller beads. Additionally, the thermal inertia of the beads results in increased time for the coating to reach the temperature required to become volatile. Therefore, large beads act slowly. Accordingly, the combination of different size beads 78 will ensure that the intensity of the smoke produced by the capsule will remain at least partially consistent. This arrangement is schematically shown in Figure 29.

Smoking intensity as a function of time curve 92a for small beads 78 is shown. Curve 92a includes a high intensity peak 94a, but the intensity increases and/or decreases rapidly over time. A second smoking intensity curve 92b is shown for a medium sized bead 78. Curve 92b includes a mid-intensity peak 94b and a mid-intensity increase and/or depletion. A third smoking intensity curve 92c is shown for the large size bead 78. Curve 92c includes a low intensity peak 94c and a slow intensity increase and/or depletion. It can be seen that each peak intensity (94a-c) is spaced apart in time.

The resulting intensity curve 96 represents the sum of curves 92a-c. In an initial stage 98a, the capsule 14 and its contents begin to heat. The result is an increase in intensity. During the intermediate step 98b, the resulting intensity remains substantially constant due to the different size beads 78 and different intensity contributions. Accordingly, intermediate step 98b provides a consistent and balanced experience to the user. Once the small and medium beads 78 are depleted and the large beads 78 begin to deplete, the resulting curve 98 enters a final stage 98c where the intensity decreases. At this point the user can stop using the device 2 and/or replace the capsule 14.

The distribution of bead 78 sizes can be adjusted so that the intermediate stage 98b provides a consistent smoking intensity 96. Although the smoking intensity of intermediate stage 98b is shown in FIG. 30 as being substantially constant, it can be appreciated that intensity 96 may be configured to lie within a certain tolerance. The error (allowable range, margin) may vary depending on the user's sensitivity to the specific product 30 used. For example, a high flavor intensity product may 'saturate' the flavor intensity experienced by the user even at low smoking intensity 96, thereby accepting a significant reduction in intensity 96. The intermediate stage 98b intensity 96 is within ±50% of the average intensity 96 at the intermediate stage 98b, preferably within ±40%; More preferably ±20% error; More preferably, it can be configured to be within ±10% error.

In some embodiments, the distribution of bead 78 sizes can be altered to vary the user experience. For example, a relatively larger number of small beads 78 may be provided to create an “intense” experience for the user. Conversely, a relatively greater number of large beads 78 may be provided to create a “smoother” experience for the user.

In some embodiments, the plurality of beads 78 may include different shapes. For example, at least one bead 78 includes a first shape, at least one bead includes a second different shape, etc. This may provide a distribution of the effective surface area of the beads 78 and thus may have the same/similar effect as varying the size of the beads 78. Accordingly, the distribution of band 78 shapes can be adjusted to change or add consistency to the user experience as described above. Different shapes may further alter the air path through the capsule 14.

Although different shapes/sizes of product 30 have been described with respect to beads 78, it will be appreciated that such arrangements may be provided if product 30 is provided in individual pieces. For example, any embodiment described herein may be provided, more specifically the following arrangement.

- Compartments 40,44/cells 42 may contain different shapes/sizes or contain different contents of product 30 therein.

- the amount of product 30 and/or the gap between the air permeable layers 36 (e.g. in FIGS. 13 and 14 )

- the amount of product disposed on the flexible sheet 48 along its length

- the size/shape of the part contained within the flexible sheet 48 (e.g. cylinder (FIG. 17), bag 60 or casing 62) and/or product contained therein 30

In some embodiments, smoking product 30 may be provided in separate pieces without individual separators or the like. This may be provided if the smoking product is solid or semi-solid.

A first example is shown in Figure 30. The capsule 14 includes a plurality of individual/individual product portions 100. The product portion 100 may be loosely contained within a capsule (eg, free flowing therein). The shape shown in Figure 30 is substantially spherical/oval, but they may include any suitable shape. The product unit 100 may provide pellets or similar products.

A second example is shown in Figure 31. Product portion 100 is substantially flat/elongated. The product portion may include shapes such as sheets, plates, strings, or flakes.

Product portion 100 may include different sizes, shapes and/or orientations to provide a consistent user experience (as described with reference to beads 78). A spare space 102 is provided within the capsule 14 so that the user can disperse the product unit 100 before use.

The product portion 100 includes a coating to prevent adhesion or merging of adjacent product portions 100. The coating can reduce the stickiness of the outer surface of the product unit 100. The coating may include powder. Therefore, the coating acts as an effective separator. The coating may include anhydrous and/or hygroscopic (moisture absorbing) materials. The coating may include an anti-caking agent.

The coating may include food-based materials. The coating is flour (wheat or corn); Sugar (for example, icing sugar); or starch (eg, potato starch).

The coating may include an inert material. The coating is sand; calcium carbonate; zeolite; Alternatively, it may contain one or more of granular/powdered minerals. The coating may include fine grained material (eg, less than 0.50 mm or less than 0.25 mm).

In some embodiments, product portion 100 may be at least partially dried, hardened, or cured to reduce external stickiness. A coating may be provided to prevent sticking to the beads 78.

In some embodiments, product 30 may include one or more inclusions therein. The enclosure may help disperse the product 30 and/or provide a path for air through the product 30.

A first embodiment is shown in Figure 32. Inclusions 86 are freely dispersed within product 30. When the capsule 14 is moved, the enclosure 86 moves freely within the product 30/capsule 14 and thus disperses the product. This can, for example, disperse the product during transport of the capsule 14, or allow the user to shake the capsule 14 before use. This arrangement may be advantageous if the product 30 is homogeneous/liquid/semi-solid, but it should be noted that the arrangement may also be useful if the product is supplied in individual pieces (e.g., to debond the beads 78). Able to know.

Enclosure 78 may include the same material as the inert filler described above. In certain examples, inclusion body 78 includes stone or rock material. Enclosure 78 may include glass beads.

In some embodiments, enclosure 78 includes a metallic material. Metallic materials can increase the effective thermal conductivity of smoking products, ensuring more even heating. Metallic materials can further act as inductors (when exposed to changing magnetic/electric fields) and provide heating of the smoking product. The metallic material may include iron. The metallic material may include ferrite (Fe ₂ O ₃ ). The metallic material may include aluminum.

In some embodiments, inclusion bodies 78 include flakes; wire; sponge; or one or more of the following wool-like arrangements.

Inclusion bodies 78 may have a diameter greater than 3 mm, 4 mm, or 5 mm; Potentially larger than 8mm or 10mm. Although the enclosure 78 shown in Figure 33 is spherical, the enclosure 78 may comprise any suitable shape, such as an oval or polyhedron.

In certain embodiments, product 30 includes shisha/tobacco products. Inclusion body 78 contains inert beads. The beads can provide air passages or break up the cigarette/hookah. In some embodiments, beads may be embedded and/or dispersed within a shisha product.

In some embodiments, beads may be provided in more than one layer. The layer may be provided at the base of the capsule. A shisha/smoking product may be placed on the beads. In some embodiments, one or more layers of beads may be placed over the shisha product. In some embodiments, the bead layers and shisha products may be provided in an alternating layer arrangement. The smoking product and/or layered arrangement may be compressed and/or compacted to mix/disperse the beads into the shisha product.

The inclusion body (78) to product (30) ratio (volume or mass) is 1:0.2-5; Preferably; 1:0.3-3; preferably 1:0.5-2; Preferably it may be 1:0.7-1.5.

As shown in Figure 33, enclosure 86 may be breathable. In some embodiments, enclosure 86 may include mesh and/or porous structures (eg, foam or pumice-like materials).

The inclusion body can passively dispense the product in the desired manner within the capsule for use. Additionally or alternatively, the capsule may be agitated immediately prior to use, so that the inclusion body helps redistribute the product within the capsule ready for use. Accordingly, the enclosure 86 may provide a more rigid structure within the product that thus serves to create the desired distribution of the product within the capsule interior.

The support structure may also increase air infiltration and/or smoke emission by providing one or more air paths and/or voids within the smoking product. Typically, the support structure and/or smoking product may only partially fill the housing, eg its internal chamber. A portion of the internal chamber may include a void, for example a gas/air filled void. The support structure and/or smoking product must not exceed 90% of the internal volume of the capsule; preferably 80% or less; preferably 70% or less; preferably 60% or less; preferably 50% or less; Preferably, it may account for 40% or less. Support structures and/or smoking products occupy at least 20% of the internal volume of the capsule; preferably 30% or more; preferably 40% or more; More preferably, it may account for 50% or more. The support structure and/or smoking product covers 20% to 90% of the internal volume of the capsule; preferably 30% to 80%; Preferably it may account for 40% to 70%.

Any of the above embodiments, or specific features thereof, may be combined with any other embodiments disclosed or claimed herein except where mutually exclusive. For example, smoking products described with any of the embodiments of Figures 25-33 may be provided in combination with any of the support structures described in any of Figures 4-18.

In any embodiment of the invention, the product within the capsule may be a liquid, viscous liquid, semi-solid/paste, or other soft/malleable solid. However, products are typically deformable to the extent that mechanical support or controlled deformation is required to achieve the desired surface profile or shape at the point of use. The product may be applied to the capsule or support structure as a flowing liquid, viscous liquid or paste, but may also be cured on the support structure, for example within the capsule, to provide a more robust product in situ. In some examples, the product may include tobacco ingredients mixed with other viscous material(s).

Although the capsule is described for use with an electronic hookah device, it will be appreciated that the capsule may be used with any suitable conventional hookah or water pipe.
