Description

A pouch, a vaporizer including the pouch, and an aerosol generating device including the pouch {A POUCH, A VAPORIZER COMPRISING THE POUCH AND AN AEROSOL GENERATING DEVICE COMPRISING THE POUCH}

Embodiments relate to a pouch, a vaporizer comprising the pouch, and an aerosol generating device comprising the pouch.

In recent years, there has been an increasing demand for alternative methods to overcome the disadvantages of regular cigarettes. For example, there is an increasing demand for a system that generates an aerosol by heating a cigarette or an aerosol-generating material using an aerosol generating device, rather than generating an aerosol by burning a cigarette. Accordingly, research on heated aerosol generating devices is actively underway.

An aerosol generating device that generates an aerosol by heating a liquid composition may include a vaporizer holding the liquid composition. The vaporizer may be formed integrally with the body of the aerosol generating device, or may be detachably coupled to it.

Vaporizers typically use materials with sealing power to prevent leakage of the liquid composition and heat resistance to withstand the heat generated to heat the liquid composition. However, the disposable vaporizer that is detachably coupled to the aerosol generating device is discarded when all the liquid composition initially held is used up, so economic efficiency is required in the manufacture and disposal of the vaporizer.

The problems to be solved through the embodiments are not limited to the above-mentioned problems, and problems not mentioned can be clearly understood by those skilled in the art from this specification and the attached drawings. will be.

A pouch according to one embodiment includes a liquid composition that is heated to generate an aerosol and a water-soluble film surrounding the liquid composition.

A vaporizer according to another embodiment includes a pouch including a liquid composition that is heated to generate an aerosol and a water-soluble film surrounding the liquid composition, and a heating unit that is detachably coupled to the pouch and heats the liquid composition.

An aerosol generating device according to another embodiment includes a pouch including a main body into which an aerosol generating article is inserted, a liquid composition that is heated to generate an aerosol, and a water-soluble film surrounding the liquid composition, and is detachably coupled to the pouch to generate the liquid. A vaporizer comprising a heating portion for heating the composition, wherein the body and the vaporizer are detachably coupled, and the aerosol generated in the vaporizer passes through the aerosol-generating article.

The solution to the problem is not limited to the above, and may include all matters that can be inferred by a person skilled in the art throughout this specification.

When the liquid composition of the pouch and the vaporizer including the same according to the embodiment is exhausted, only the pouch can be replaced with a new pouch and the other members can be used continuously. Since the pouch contains a water-soluble film, it can be disposed of simply and economically by simply exposing the used pouch to water. In addition, since the water-soluble film of the pouch is light in weight and relatively free in shape, it is easy to replace and can contain a relatively large amount of liquid composition.

The effects of the embodiments are not limited to those described above, and may include all effects that can be inferred from the configuration described later.

In Figure 1, the battery 110, control unit 120, vaporizer 140, and heater 130 are shown arranged in a line. Additionally, Figure 2 shows the vaporizer 140 and the heater 130 being arranged in parallel. However, the internal structure of the aerosol generating device 100 is not limited to that shown in FIG. 1 or FIG. 2. In other words, depending on the design of the aerosol generating device 100, the arrangement of the battery 110, control unit 120, vaporizer 140, and heater 130 may be changed.

When the aerosol generating article 200 is inserted into the aerosol generating device 100, the aerosol generating device 100 may operate the vaporizer 140 to generate an aerosol from the vaporizer 140. The aerosol generated by vaporizer 140 passes through aerosol generating article 200 and is delivered to the user. A description of the vaporizer 140 will be provided in more detail below.

The battery 110 supplies power used to operate the aerosol generating device 100. For example, the battery 110 may supply power so that the heater 130 or the vaporizer 140 can be heated, and may supply power necessary for the control unit 120 to operate. Additionally, the battery 110 can supply power necessary to operate a display, sensor, motor, etc. installed in the aerosol generating device 100.

The processor may be implemented as an array of multiple logic gates, or as a combination of a general-purpose microprocessor and a memory storing a program that can be executed on the microprocessor. Additionally, those skilled in the art can understand that the present embodiment may be implemented with other types of hardware.

The heater 130 may be heated by power supplied from the battery 110. For example, when the aerosol-generating article 200 is inserted into the aerosol-generating device 100, the heater 130 may be positioned external to the aerosol-generating article 200. Accordingly, the heated heater 130 may increase the temperature of the aerosol-generating material within the aerosol-generating article 200.

The heating element is an element for heating the liquid composition delivered by the liquid delivery means. For example, the heating element may be a metal heating wire, a metal heating plate, a ceramic heater, etc., but is not limited thereto. Additionally, the heating element may be composed of a conductive filament, such as a nichrome wire, and may be arranged in a structure wound around the liquid delivery means. The heating element may be heated by supplying an electric current and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, aerosols may be generated.

For example, the vaporizer 140 may be referred to as a cartomizer or an atomizer, but is not limited thereto.

Meanwhile, the aerosol generating device 100 may further include general-purpose components in addition to the battery 110, the control unit 120, the heater 130, and the vaporizer 140.

The user may inhale the aerosol while holding the second portion with his or her mouth. At this time, the aerosol is generated when external air passes through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.

As an example, external air may be introduced through at least one air passage formed in the aerosol generating device 100. For example, the opening and closing of the air passage formed in the aerosol generating device 100 and/or the size of the air passage may be adjusted by the user. Accordingly, the amount of atomization, smoking sensation, etc. can be adjusted by the user. As another example, outside air may be introduced into the interior of the aerosol-generating article 200 through at least one hole formed on the surface of the aerosol-generating article 200.

If the filter rod 220 includes a segment that cools the aerosol, the cooling segment may be made of a polymer material or a biodegradable polymer material. For example, the cooling segment may be fabricated from pure polylactic acid alone, but is not limited to this. Alternatively, the cooling segment can be made from a cellulose acetate filter with a plurality of holes drilled into it. However, the cooling segment is not limited to the above-described example, and may be applicable without limitation as long as the aerosol can perform the function of cooling.

Referring to FIG. 4 , the aerosol generating article 300 may further include a shear plug 330 . The shear plug 330 may be located on one side of the tobacco rod 310 opposite to the filter rod 320. The front end plug 330 can prevent the cigarette rod 310 from leaving the outside, and prevents the liquefied aerosol from the cigarette rod 310 from flowing into the aerosol generating device (100 in FIGS. 1 and 2) during smoking. It can be prevented.

Hereinafter, a pouch according to an embodiment will be described with reference to the drawings.

5 to 7 are diagrams showing the appearance of the pouch 10 according to one embodiment. FIG. 5 is a perspective view showing the pouch 10 according to an embodiment, FIG. 6 is a view of the pouch 10 of FIG. 5 viewed from the x-y plane, and FIG. 7 is a view of the pouch 10 of FIG. 5 viewed from the x-z plane. It is a drawing.

Referring to FIGS. 5 to 7 , the pouch 10 according to one embodiment may include a liquid composition and a water-soluble film surrounding the liquid composition.

The pouch 10 according to one embodiment may have a water-soluble film 13 forming the exterior, and a space blocked from the outside may be formed inside the pouch 10. A liquid composition may be located in the space formed inside the pouch 10. For example, as shown in FIGS. 5 to 7, the pouch 10 according to one embodiment may form a space inside the pouch 10 by bonding the edges of two water-soluble films 13 to each other. However, it is not limited to this, and two or more water-soluble films 13 may be used, or the internal space may be formed by a single water-soluble film 13.

At least a portion of the water-soluble film 13 may be transparent. The user can visually check the liquid composition remaining inside through the transparent portion of the water-soluble film 13. For example, the water-soluble film 13 may be transparent due to the physical properties of the material forming the water-soluble film 13. 5 to 7 show an example of the pouch 10 formed of the water-soluble film 13 whose entire area is transparent, but is not limited thereto. As another example, the water-soluble film 13 may include a separate transparent area made of a different material from the water-soluble film 13.

The water-soluble film 13 refers to a flexible film that has the property of dissolving in contact with water. The water-soluble film 13 may include a water-soluble polymer. For example, the water-soluble film 13 is made of polyvinyl alcohol, polyvinylpyrrolidone, sodium alginate, pulluran, xanthan gum, polyethylene oxide, It may include one or more water-soluble polymers selected from the group consisting of starch or starch derivatives, gelatin, and alkyl cellulose.

Here, alkylcellulose may mean one or more selected from the group consisting of methylcellulose, hydroxypropylmethyl cellulose, carboxymethylcellulose, hydroxymethylcellulose, and hydroxypropylcellulose.

The water-soluble film 13 may contain additives that improve heat resistance. The additive may be one or more selected from the group consisting of silicon, silica, calcium chloride, zeolite, and clay. Here, the clay may be selected from saponite (SPT), montmorillonite (MMT), hectorite (SWN), water-soluble bentonite (PGV), mica (Mica), and mixtures thereof.

For example, the water-soluble film 13 can be produced by casting a homogeneous slurry prepared by mixing 5 to 20 parts by weight of water-soluble polymer and 1 to 3 parts by weight of additives based on 100 parts by weight of distilled water and then drying.

A liquid composition that is heated to generate an aerosol may be located in the internal space of the pouch 10. As will be described later, the liquid composition inside the pouch 10 is discharged to the outside of the pouch 10, and an external heating element heats the discharged liquid composition, thereby generating an aerosol.

The contents previously described with respect to FIGS. 1 and 2 may be equally applied to the liquid composition. For example, liquid compositions may include water, solvents, ethanol, plant extracts, fragrances, flavors, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit flavor ingredients. Flavoring agents may include ingredients that can provide various flavors or flavors to the user. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E. Additionally, the liquid composition may contain aerosol-generating substances such as glycerin and propylene glycol.

The pouch 10 according to one embodiment is located inside the pouch 10 and may include a support 14 that supports the shape of the pouch 10. Support 14 may be made of metal, plastic and/or paper, but is not limited thereto. The support 14 is located inside the pouch 10 and can prevent the shape of the pouch 10 from being deformed as the liquid composition is consumed.

Since the outer shape of the pouch 10 is formed of a flexible water-soluble film 13, it can be changed depending on the amount of liquid composition contained therein. If there is a relatively large amount of liquid composition remaining inside the pouch 10, the outer shape of the pouch 10 may be maintained due to the volume occupied by the liquid composition, but otherwise, the outer shape of the pouch 10 may not be maintained. there is. If the outer shape of the pouch 10 is not maintained, the liquid composition inside the pouch 10 may not be smoothly discharged to the outside, and as a result, unwanted liquid composition may remain inside the pouch 10. . Additionally, the water-soluble film 13 may not be able to withstand shape deformation due to external pressure and may rupture. By minimizing deformation of the shape of the pouch 10, the support 14 can prevent problems such as unwanted liquid composition remaining inside the pouch 10 or rupture of the water-soluble film 13.

Referring to FIGS. 5 to 7 , a plurality of supports 14 may be arranged inside the pouch 10 to be spaced apart from each other. Additionally, the support 14 may extend in the z-axis direction, and both ends of the support 14 may contact the inner surface of the water-soluble film 13. However, it is not limited to this, and the shape, arrangement, and number of supports 14 may be modified in various ways as long as they can maintain the shape of the pouch 10. For example, the cross-sectional area of one end of the support 14 may be larger than the cross-sectional area between both ends of the support 14. As another example, the plurality of supports 14 may be arranged to extend in a direction crossing each other. As another example, a single support 14 may be disposed in the pouch 10.

The pouch 10 according to one embodiment is detachably coupled to the heating unit 141 of the vaporizer and can replace the function of the liquid storage unit. A description of the vaporizer including the pouch 10 according to one embodiment will be provided with reference to FIGS. 8 and 9 below.

Referring to FIG. 8, the vaporizer according to the embodiment includes a pouch 10 according to an embodiment and a heating unit 141 that is detachably coupled to the pouch 10 and heats the liquid composition. The contents described above in the description of FIGS. 1 and 2 may be equally applied to the vaporizer according to the embodiment.

The heating unit 141 may include a liquid delivery means 143 and a heating element 142. The liquid delivery means 143 may deliver the liquid composition of the liquid reservoir to the heating element 142. For example, the liquid delivery means 143 may be a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited thereto. The liquid delivery means 143 absorbs the liquid composition, and the liquid composition absorbed by the liquid delivery means 143 may move toward the heating element 142.

The heating element 142 is an element for heating the liquid composition delivered by the liquid delivery means 143. For example, the heating element 142 may be a metal heating wire, a metal heating plate, a ceramic heater, etc., but is not limited thereto. Additionally, the heating element 142 may be composed of a conductive filament, such as a nichrome wire, and may be arranged in a structure wound around the liquid delivery means 143. The heating element 142 can be heated by supplying an electric current and can transfer heat to the liquid composition in contact with the heating element 142, thereby heating the liquid composition. As a result, aerosols may be generated.

The water-soluble film 13 according to the embodiment may include a first coupling portion 11 coupled to the heating portion 141. For example, the first coupling portion 11 may be a ring-shaped member with elasticity. One side of the ring-shaped first coupling portion 11 may be adhered to the water-soluble film 13 of the pouch 10. At this time, a hole of a small size compared to the ring-shaped size of the first coupling part 11 may be formed in the heating unit 141, and the first coupling part 11 may be formed in the heating unit 141 in a compressed state. It can be coupled to the heating unit 141 by passing through the hole. Since the water-soluble film 13 has flexibility and elasticity, only the first coupling portion 11 can be stretched to pass through the hole of the heating unit 141.

However, the method in which the first coupling portion 11 and the heating portion 141 are coupled is not limited to this. For example, the first coupling portion 11 may be a hard member and may be coupled to the heating portion 141 in an interference fit manner.

When combined with the heating unit 141, a hole may be formed in the first coupling unit 11. The heating unit 141 may include a needle tip for forming a hole in the first coupling part 11 during the coupling process with the first coupling part 11 . The liquid composition of the pouch 10 may be discharged to the outside of the pouch 10 through a hole formed in the first coupling portion 11. The liquid composition discharged through the hole formed in the first coupling portion 11 may move toward the heating element 142 through the liquid transfer means 143. Here, the first coupling portion 11 may contact the liquid delivery means 143 when coupled with the heating portion 141.

The heating unit 141 may further include an insulating unit 144 disposed between the pouch 10 and the heating element 142. The insulation portion 144 may block at least a portion of the heat transmitted from the heating element 142 toward the pouch 10. The water-soluble film 13 of the pouch 10 may lack heat resistance due to the nature of the material and may be damaged when exposed to excessive heat. The insulation unit 144 blocks heat generated from the heating element 142, thereby preventing the water-soluble film 13 of the pouch 10 from being exposed to excessive heat.

The insulating portion 144 may have a shape surrounding the heating element 142 to improve the insulating effect. In this case, the liquid delivery means 143 may penetrate the insulation portion 144. A hole through which the liquid delivery means 143 passes may be formed in the insulation portion 144.

The insulation portion 144 may include a plastic material with excellent insulation properties. For example, the insulation portion 144 is made of polycarbonate (PC), acrylonitrile-butadiene-styrene resin (ABS), polyetheretherketone (PEEK), polysulfone (PSU), liquid crystal polymer (LCP), and polyether. It may include one or more types of plastic selected from the group consisting of mead (PEI), polyethersulfone (PES), polyphenylenesulfone (PPS), and polyimide (PI). However, it is not limited to this, and any plastic that has sufficient thermal insulation properties to block heat moving from the heating element 142 toward the pouch 10 can be used without limitation.

The heating unit 141 may include at least one rib 145 (rib). The rib 145 is formed on one side of the heating unit 141 and may extend from the heating element 142 toward the pouch 10. The pouch 10 may include a second coupling portion 12 coupled to the rib 145. The rib 145 may fix the position of the pouch 10 coupled to the heating unit 141. Since the water-soluble film 13 of the pouch 10 has flexibility and elasticity, even if it is coupled to the heating unit 141 by the first coupling part 11, the water-soluble film 13 of the pouch 10 is relatively distant from the first coupling part 11. The position may not be fixed. The rib 145 may be additionally coupled to the second coupling portion 12 of the pouch 10, thereby fixing the position of the pouch 10.

The heating unit 141 may include a plurality of ribs 145, and the pouch 10 may include a plurality of second coupling portions 12 for coupling to the plurality of ribs 145. The second coupling portion 12 may include a hole formed at the edge of the pouch 10. The rib 145 of the heating unit 141 may be coupled to the pouch 10 by penetrating the hole of the second coupling unit 12. However, the method by which the second coupling portion 12 and the rib 145 are coupled is not limited to this. For example, the second coupling portion 12 may be coupled to the rib 145 using a Velcro method.

Figure 9 is a cross-sectional view of a vaporizer according to another embodiment.

Referring to FIG. 9, the vaporizer includes a pouch 10 and a heating unit 141 that is detachably coupled to the pouch 10 and heats the liquid composition. The contents described above in the description of FIG. 8 may be equally applied to the vaporizer shown in FIG. 9 .

The vaporizer may further include a pressing portion 147 that applies pressure to the pouch 10 in a direction toward the heating element 142. The pressing unit 147 can press the flexible pouch 10 so that the liquid composition of the pouch 10 is completely transferred to the heating element 142 without remaining inside the pouch 10. Figure 9 shows an example in which the pressing unit 147 presses the pouch 10 using an elastic member, but the present invention is not limited thereto. As another example, the pressing part 147 may be an electrically operated pressing member.

If the vaporizer includes a pressurizing portion 147, the pouch 10 may not include a support therein. Since the liquid composition can be completely transferred to the heating element 142 by the pressing portion 147, the need for a support to help transfer the liquid composition can be reduced by maintaining the external shape of the pouch 10.

The vaporizer may include a cover 146. Here, the pressing portion 147 may be disposed on the inner surface of the cover 146. The cover 146 may block the pouch 10 from the outside after the pouch 10 is coupled to the heating unit 141. Accordingly, the water-soluble film 13 can be prevented from being ruptured by external factors. Figure 9 shows an example in which the cover 146 operates in an opening and closing manner, but is not limited thereto. As another example, the cover 146 may operate in a sliding manner.

In the vaporizer according to one embodiment, the pouch 10 containing the liquid composition is detachably coupled, so when the liquid composition is exhausted, only the pouch 10 can be replaced and used, and the heating unit 141 is continuously operated. You can utilize it. Additionally, since the pouch 10 includes a water-soluble film 13, the used pouch 10 can be disposed of simply and economically by exposing it to water. Since the water-soluble film 13 of the pouch 10 is light in weight and relatively free in shape, it is easy to replace compared to using a hard liquid storage unit, and can contain a relatively large amount of liquid composition.

FIG. 10 is a diagram showing an example of an aerosol generating device 100 combined with the vaporizer 140 of FIG. 9.

Referring to FIG. 10, the aerosol generating device 100 includes a battery 110, a control unit 120, a heater 130, and a vaporizer 140.

FIG. 10 shows a heater 130 that heats the aerosol-generating article 200 inserted into the main body of the aerosol-generating device 100, but the heater may be omitted from the aerosol-generating device 100. When the heater is omitted in the aerosol generating device 100, the high-temperature aerosol generated in the vaporizer 140 passes through the aerosol-generating article 200 and can indirectly heat the aerosol-generating article 200. At this time, the tobacco load of the aerosol-generating article 200 may include a plurality of tobacco granules.

Tobacco granules can be produced by wet extrusion of a mixture of tobacco material, pH adjuster, and solvent. Tobacco granules can have a diameter of about 0.5 to about 1.5 mm. The tobacco material can be, for example, tobacco leaves, tobacco veins, puffed tobacco, cut cut, leaf cut, reconstituted tobacco, tobacco extract, and combinations thereof.

Tobacco granules can have a basic pH by means of a pH adjusting agent. For example, tobacco granules can have a pH value of about 7.0 to about 9.0. Some of the nicotine contained in the tobacco material can be converted from nicotine salt to freebase nicotine by a pH adjuster. Freebase nicotine has a relatively low boiling point and high volatility compared to nicotine salts. Therefore, tobacco granules can generate nicotine vapor even under relatively low temperature heating conditions.

The pH adjuster includes alkali metal carbonate, alkaline earth metal carbonate, alkali metal hydrogencarbonate, alkaline earth metal hydrogencarbonate, alkali metal hydroxide, alkaline earth metal hydroxide, alkali metal phosphate, alkaline earth metal phosphate, alkali metal phosphate monohydrogenate and alkaline earth metal phosphate monohydrogenate. It may include one or more types. For example, the pH adjuster may include one or more of sodium carbonate, potassium carbonate, calcium carbonate, sodium hydroxide, potassium hydroxide, calcium hydroxide, and calcium oxide.

Tobacco granules may further contain a binder. The binder can bind the tobacco material, pH adjuster, and solvent together to bring them together. The binder may be, for example, hydroxy propyl cellulose (HPC) or hydroxy propyl methyl cellulose (HPMC).

Tobacco granules may further contain aerosol-generating substances. Here, the aerosol-generating material may include, for example, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

A plurality of tobacco granules may be placed in a cavity formed by being surrounded by a wrapper, but the present invention is not limited thereto. For example, a plurality of tobacco granules may be embedded between filter materials. The filter material may comprise a fiber bundle of cellulose acetate fiber strands. A plurality of tobacco granules may be disposed in a uniformly dispersed form between cellulose acetate fibers.

As another example, the filter material may include a paper sheet. The paper sheet may be placed inside the tobacco rod in a rolled state. The central axis of the rolled paper sheet may be parallel to the longitudinal direction of the aerosol-generating article 200. A plurality of tobacco granules may be uniformly dispersed inside the rolled paper sheet.
