[0023] As shown in the figure, an embodiment of the present invention provides a loading unit, comprising: a wrapping layer 1, a packaging layer 2, The wrapping layer 1 and the encapsulation layer 2 are connected to form a closed cavity 3, and the cavity 3 is filled with essence; The material of the packaging layer 2 is a material that degrades or deforms when heated.

[0024] The present application first provides a loading unit, comprising: a wrapping layer 1, an encapsulation layer 2, the wrapping layer 1 and the encapsulation layer 2 are connected to form a closed cavity 3, and the cavity 3 is filled with flavors; the material of the encapsulation layer 2 is a material that is degraded or deformed by heat. The loading unit provided by the present application uses the closed cavity 3 formed between the wrapping layer 1 and the encapsulation layer 2 to fill the flavors, so as to achieve long-term sealed storage of the flavors, which can effectively keep the flavors from escaping during storage, and keep their properties and concentrations stable. At the same time, the material of the encapsulation layer 2 used in the loading unit is a material that is degraded or deformed by heat, and the loading unit is placed in a heated cigarette. When the smoke temperature is usually between 90°C and 100°C during smoking, the heat carried by the smoke acts on the encapsulation layer 2, causing it to degrade or deform, and the encapsulation layer 2 itself disappears or holes appear, or the connection between the encapsulation layer 2 and the wrapping layer 1 is destroyed, so that the seal of the cavity 3 is broken, and the flavors in the cavity 3 are released, and are inhaled and tasted by consumers together with the aerosol generated by the heating of the smoking substance, and the characteristic fragrance represented by the flavor is significant, enriching the smoking experience.

[0025] The encapsulation layer 2 may be degraded or deformed by heat, which may be deformation alone, degradation alone, or both. The deformation may be cracking, shrinking, curling, etc. of the encapsulation layer 2, and the degradation may be melting of the encapsulation layer 2, etc., which may cause the connection between the encapsulation layer 2 and the wrapping layer 1 to move relative to each other, or destroy the structure of the encapsulation layer 2 itself, thereby destroying the airtightness of the cavity 3.

[0026] The loading unit provided in the present application has no special requirements for the type of flavors, and any flavor commonly used in the tobacco field can be used, for example, mint flavors, etc. Preferably, the flavors are mixed with ethanol, propylene glycol, and caprylic decanoate (ODO) as solvents and then injected into the cavity 3.

[0027] Preferably, the material of the encapsulation layer 2 is one or more of polyhydroxyalkanoate, polybutylene adipate / terephthalate, polycaprolactone, and polybutylene succinate; The material of the wrapping layer 1 is one or more of polylactic acid, polypropylene and polyethylene.

[0028] The material of the preferential encapsulation layer 2 is one or more of polyhydroxyalkanoate (PHA), polybutylene adipate / terephthalate (PBAT), polycaprolactone (PCL), and polybutylene succinate (PBS). The above materials can not only remain stable at the temperature of daily storage of cigarettes and degrade or deform when heated, but also are degradable polymer materials and are environmentally friendly.

[0029] The material of the wrapping layer 1 can be one or more of polylactic acid, polypropylene, and polyethylene, which can maintain stability and facilitate the preservation of the flavor.

[0030] Preferably, the encapsulation layer 2 is a flat plate, and the wrapping layer 1 is concave to form a cavity 3 .

[0031] Preferably, the encapsulation layer 2 is made into a flat plate, and the wrapping layer 1 is concave to form a cavity 3. The essence is completely injected into the wrapping layer 1, and then the flat encapsulation layer 2 is connected to the edge of the wrapping layer 1 to achieve the sealing of the cavity 3, which is easy to shape and connect.

[0032] Preferably, the volume of the essence loaded in the cavity 3 is 20-40 μl, and the volume of the cavity 3 is greater than the volume of the essence.

[0033] Preferably, the volume of the essence injected into the cavity 3 is between 20 and 40 microliters, which can achieve a good flavoring effect; and the volume of the cavity 3 is larger than the volume of the injected essence (for example, when the volume of the essence is 40 microliters, the volume of the cavity 3 is 45 or 50 microliters, etc.), and the cavity 3 formed by the concave wrapping layer 1 can be first loaded with all the essence into the cavity 3. At this time, there will be some gaps on the top of the cavity 3, which can prevent the essence from overflowing when the wrapping layer 1 and the encapsulation layer 2 are connected, or the essence from overflowing the connection, causing adverse effects on the connection between the wrapping layer 1 and the encapsulation layer 2.

[0034] The volume of the injected flavor can be loaded by an industrial pump in a quantitative injection manner to ensure that the volume meets the current set value.

[0035] Preferably, the thickness of the encapsulation layer 2 is 30-60 microns; The thickness of the wrapping layer 1 is 40-80 microns.

[0036] Preferably, the thickness of the packaging layer 2 is 30-60 microns, which can prevent the packaging layer 2 from breaking during daily transportation and storage, and can also meet the requirement of being degraded or deformed when the cigarette is heated during smoking.

[0037] Preferably, the thickness of the wrapping layer 1 is 40-80 microns.

[0038] Preferably, the wrapping layer 1 and the packaging layer 2 are connected by heat pressing or ultrasonic welding.

[0039] Preferably, the hot pressing temperature is 100-150°C.

[0040] Preferably, the connection between the wrapping layer 1 and the encapsulation layer 2 is formed by hot pressing or ultrasonic welding, which is simple, fast and easy for industrial production and operation. More preferably, the hot pressing temperature is 100-150°C.

[0041] Preferably, the encapsulation layer 2 and the wrapping layer 1 respectively form two cavities 3, one of the cavities 3 is filled with essence, and the other cavity 3 is filled with glycerin.

[0042] More preferably, the encapsulation layer 2 and the wrapping layer 1 form two cavities 3, wherein flavor is filled in one cavity 3 and glycerin is filled in the other cavity 3. By adding glycerin to the cavity 3, the amount of smoke during inhalation can be significantly increased, and the increased smoke and the atomized flavor enter the consumer's mouth at the same time, improving the inhalation experience, solving the problem of unclear flavor enhancement and the problem of small amount of smoke in heated cigarettes.

[0043] Similarly, the method of forming a closed cavity 3 by using the encapsulation layer 2 and the wrapping layer 1 can also ensure that the content and properties of glycerin are stable during long-term storage and transportation.

[0044] Preferably, the two cavities 3 are respectively located on two sides of the encapsulation layer 2 , and adjacent surfaces of the two cavities 3 are at least partially staggered.

[0045] More preferably, the two cavities 3 are located on both sides of the encapsulation layer 2, and the adjacent surfaces of the two cavities 3 are at least partially staggered (the adjacent surfaces are the encapsulation layers 2), so that the encapsulation layer 2 will not be blocked by the wrapping layer 1 to affect its deformation or degradation.

[0046] A heated cigarette comprises any one of the above-mentioned loading units.

[0047] The present application also provides a heated cigarette, comprising any of the above-mentioned loading units.

[0048] More preferably, the loading unit is placed in the viewing window of the heated cigarette, which can not only provide the effect of enhancing the flavor and increasing the amount of smoke, but also enable consumers to intuitively observe the changes in the smoke, thereby increasing the interactive experience of smoking.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
