[0028] This application provides a storage device for storing oral contents. See also... Figures 1-3 The storage device 100 may include a base 10 and a cover 20. The base 10 has a certain accommodating space for storing oral contents. The base 10 has a first opening 12 for inserting or removing oral contents. The cover 20 covers the first opening 12. The inner space formed by the cover 20 and the base 10 has at least two mutually isolated storage cavities 13 for storing oral contents. The number of storage cavities 13 may be two, three, four, or more. The isolation between the storage cavities 13 prevents moisture exchange between the air within each storage cavity 13, allowing each storage cavity 13 to independently store multiple oral contents.

[0029] Please see Figure 3A humidity retainer 40 is provided for at least one storage cavity 13. The humidity retainer 40 is used to maintain the humidity in the corresponding storage cavity 13 so that the storage device 100 can store at least two types of oral contents with different humidity requirements. For example, for dry products that require moisture protection, the humidity retainer 40 can maintain the humidity in the storage cavity 13 in a lower range; or for wet products that require protection against water loss, the humidity retainer 40 can maintain the humidity in the storage cavity 13 in a higher range. A humectant may be added to the oral contents during preparation to prevent water loss. Even with the same water content, oral contents with added humectant have different humidity requirements during storage compared to those without. Each storage cavity 13 may be equipped with a humidity retainer 40, in which case each storage cavity 13 can store at least two types of oral contents with different moisture contents. The two types of oral contents with different moisture contents may be prepared using different methods or prepared using the same method, so that the storage device 100 can store at least two types of oral contents with different humidity requirements. Alternatively, some storage cavities 13 may be equipped with a humidity retainer 40, while other storage cavities 13 may not be equipped with a humidity retainer 40. In this case, some storage cavities 13 can store oral contents without added humectant, while other storage cavities 13 can store oral contents with added humectant, so that the storage device 100 can store at least two types of oral contents with different humidity requirements.

[0030] The storage device 100 provided in this application is provided with a humidity retainer 40 corresponding to at least one storage cavity 13. The humidity retainer 40 is used to maintain the humidity in the corresponding storage cavity 13 so that the storage device 100 can store at least two oral contents with different humidity requirements, thereby increasing the types of oral contents that the storage device 100 can store and expanding the application scenarios of the storage device 100.

[0031] In one embodiment, the humidity retainer 40 includes a water-absorbing agent and a slow-release agent. The water-absorbing agent is used to absorb moisture from the air inside the storage cavity 13, thereby maintaining the humidity in the storage cavity 13 at a low range to keep the storage cavity 13 dry; the slow-release agent is used to release moisture into the air inside the storage cavity 13, thereby maintaining the humidity in the storage cavity 13 at a high range to maintain the appropriate humidity in the storage cavity 13. At least one storage cavity 13 is provided with a water-absorbing agent, so that at least one storage cavity 13 can be used to store oral contents prepared by dry method; and at least one storage cavity 13 is provided with a slow-release agent, so that at least one storage cavity 13 can be used to store oral contents prepared by wet method. Therefore, the storage device 100 simultaneously meets the needs of moisture prevention for dry products and water loss prevention for wet products, and can simultaneously store oral contents prepared by dry and wet methods, thereby expanding the application scenarios of the storage device 100.

[0032] The moisture-retaining agent 40 can be in the form of sheets or blocks. In one embodiment, the desiccant includes one of silica gel desiccant, molecular sieve desiccant, activated carbon desiccant, and polymer desiccant. All of the above desiccant have strong adsorption capacity and can adsorb excess moisture in the air within the corresponding storage cavity 13, preventing the product from becoming damp.

[0033] In one embodiment, the slow-release agent includes one of polyvinyl alcohol slow-release agent, carboxymethyl cellulose slow-release agent, sodium alginate slow-release agent, and polyacrylamide slow-release agent. The aforementioned slow-release agent combines with water to form a material with a high water content, slowly releasing moisture to gradually replenish the air within the corresponding storage cavity 13, thus helping to maintain suitable humidity for the product.

[0034] The first opening 12 can be formed on the side of the seat 10, and correspondingly, the oral object is inserted or removed from the side of the seat 10. In one embodiment, the storage device 100 has a height direction, and the seat 10 has a first opening 12 at one end in the height direction. Exemplarily, the storage device 100 can be generally cylindrical, and its cross-section can be circular, elliptical, or polygonal. The height direction can be... Figure 3 In the Z-axis direction, the first opening 12 can be opened on the top surface of the seat 10. Setting the first opening 12 at one end of the seat 10 in the height direction can reduce damage to the side wall of the seat 10 and help increase the effective accommodation space of the seat 10.

[0035] Humidifier 40 can be placed inside storage cavity 13. For example, as... Figure 4 As shown, when the storage cavity 13 is formed by the cover 20 and the base 10, the contents are contained in the base 10, and the humidity retainer 40 can be fixed to the cover 20, thereby maintaining the humidity in the storage cavity 13 within a preset range. In one embodiment, as... Figure 2 , Figure 3As shown, the humidity retainer 40 is placed outside the storage cavity 13. The storage device 100 includes a first inner shell assembly 30, which is at least partially housed within the base 10. That is, the first inner shell assembly 30 can be entirely housed within the base 10, or only partially housed within the base 10. The first inner shell assembly 30 is disposed between the cover 20 and the base 10, and seals the storage cavity 13 to reduce the risk of moisture or water loss of the contents in the storage cavity 13. The first inner shell assembly 30 has at least two mutually isolated retainer receiving cavities 312 formed on the side facing the storage cavity 13. Each retainer receiving cavity 312 is respectively disposed corresponding to one storage cavity 13, and the humidity retainer 40 is housed in the retainer receiving cavity 312. The retainer receiving cavity 312 is configured to allow the humidity retainer 40 at the corresponding position to exchange moisture with the internal air of the storage cavity 13. The humidity retainer 40 is placed in the retainer receiving cavity 312, while the oral contents are placed in the storage cavity 13. The humidity retainer 40 and the oral contents in the storage cavity 13 are isolated from each other, which can prevent the humidity retainer 40 from directly contacting part of the oral contents, thereby avoiding the humidity retainer 40 acting only on part of the oral contents. The humidity retainer 40 positioned in the corresponding position of the retainer receiving cavity 312 can exchange moisture with the internal air of the storage cavity 13, which can maintain the humidity in the storage cavity 13 within a preset range and reduce the risk of the oral contents in the storage cavity 13 becoming damp or losing water.

[0036] The cavity wall of the moisture-retaining agent receiving cavity 312 may have micropores, allowing the moisture-retaining agent 40 to exchange moisture with the internal air of the storage cavity 13 through the micropores, but the moisture-retaining agent 40 does not directly contact the oral contents. In one embodiment, such as Figure 2 , Figure 3 As shown, the first inner shell assembly 30 includes a first inner shell 31, a sealing sheet 32, and a water-permeable membrane 33. The first inner shell 31 is at least partially housed within the base 10. The first inner shell 31 has a second opening 311 on the side facing the cover 20, which can be used to insert a humidity retainer 40 or the sealing sheet 32. A water-permeable membrane 33 is provided at the end of the first inner shell 31 away from the second opening 311. The sealing sheet 32, the water-permeable membrane 33, and the first inner shell 31 enclose a humidity retainer receiving cavity 312. This arrangement places the storage cavity 13 between the water-permeable membrane 33 and the base 10. The water-permeable membrane 33 allows water molecules to pass freely but prevents large molecules or particles from passing through, thereby preventing the humidity retainer 40 from directly contacting part of the contents. The humidity retainer 40 is attached to the water-permeable membrane 33. The humidity retainer 40 can exchange moisture with the internal air of the adjacent storage cavity 13 through the water-permeable membrane 33. A humidity retainer 40 is attached to the water-permeable membrane 33 so that the humidity retainer 40 is closer to the storage cavity 13, so as to maintain the humidity in the storage cavity 13 within a preset range.

[0037] The sealing sheet 32 ​​can be a separate structure, for example, each retainer cavity 312 has a sealing sheet 32; or the sealing sheet 32 ​​can be an integral structure, for example, multiple retainer cavities 312 share one sealing sheet 32. The sealing sheet 32 ​​can be integrally formed into the first inner shell 31, that is, the sealing sheet 32 ​​and the first inner shell 31 are a single piece; or the sealing sheet 32 ​​can be assembled and connected to the first inner shell 31, that is, the sealing sheet 32 ​​and the first inner shell 31 are separate pieces.

[0038] The sealing plate 32 can be flush with the end of the first inner shell 31 near the second opening 311 to reduce the gap between the sealing plate 32 and the cover 20, thereby increasing the effective accommodating space of the seat 10. (See also...) Figure 3 In one embodiment, a cover 20 is disposed over the second opening 311, and a sealing sheet 32 ​​is housed within the first inner shell 31. The sealing sheet 32, the first inner shell 31, and the cover 20 together form a recycling cavity 313, which is used to hold used oral contents. The end of the first inner shell 31 near the second opening 311 protrudes from the sealing sheet 32, which may be located at the midpoint of the first inner shell 31 in the height direction. The recycling cavity 313 facilitates the placement of used oral contents by the user, contributing to environmental cleanliness. The cover 20, positioned over the second opening 311, can open or close the recycling cavity 313 to facilitate the placement of used oral contents and prevent them from falling from the storage device 100 and contaminating the environment.

[0039] In one embodiment, such as Figure 3 , Figure 5 As shown, the first inner shell 31 is provided with a first limiting flange 34 on its outer periphery at the second opening 311. The first limiting flange 34 is engaged at the first opening 12 of the seat body 10. The first limiting flange 34 is engaged at the end of the seat body 10, which can both seal the seat body 10 and enhance the airtightness of the storage cavity 13, and expose the first limiting flange 34 to the outside air, so that the user can easily hold the first limiting flange 34 to remove the first inner shell assembly 30 from the seat body 10.

[0040] In one embodiment, such as Figure 3 , Figure 5 As shown, a second limiting flange 35 is provided on the inner wall of the middle part of the first inner shell 31 in the height direction. The sealing sheet 32 ​​is disposed on the second limiting flange 35. The second limiting flange 35 supports the sealing sheet 32 ​​and can prevent the sealing sheet 32 ​​from shifting, thereby enhancing the airtightness of the retainer cavity 312.

[0041] In one embodiment, the material of the first inner shell includes polyethylene, polypropylene, or polystyrene. These materials exhibit good chemical stability and low moisture absorption, which can reduce interference from the first inner shell with the humidity retainer 40 in the retainer-containing cavity 312. Furthermore, these materials are easy to clean and maintain, thereby facilitating the cleaning of the recovery cavity 313.

[0042] In one embodiment, the sealing sheet is made of one of the following materials: silicone rubber, ethylene propylene rubber silicone rubber, fluororubber, or nitrile rubber. These materials possess good flexibility and sealing properties, effectively isolating different storage environments and preventing moisture exchange.

[0043] In one embodiment, the material of the permeable membrane includes one of polytetrafluoroethylene, polyethylene, polypropylene, or nylon. These materials possess good chemical stability and breathability, allowing water molecules to pass freely while preventing the passage of large molecules or particles, effectively isolating the humidity retainer 40 from the contents in the storage cavity 13.

[0044] The oral contents can be stored in the seat 10. For example, such as Figure 4 As shown, the cover 20 and the base 10 enclose a storage cavity 13. (See also...) Figure 2 , Figure 3 In one embodiment, the storage device 100 includes a second inner shell assembly 50, in which the oral contents are stored. The second inner shell assembly 50 is detachably housed within the base 10. For example, the second inner shell assembly 50 may be bonded to the base 10 or interference-fitted into the base 10. The detachable nature of the second inner shell assembly 50 allows it to be relatively independent of the base 10. Once all the oral contents within the second inner shell assembly 50 have been used, the second inner shell assembly 50 can be easily separated from the base 10. The base 10 can then be reused by replacing the second inner shell assembly 50, thereby reducing user costs. Furthermore, by providing the second inner shell assembly 50, the oral contents can be independently sealed within it. Before being opened and used, the oral contents are isolated from air, reducing the evaporation of water, fragrances, nicotine, and other active substances, thus extending shelf life. The second inner shell assembly 50 includes a second inner shell 51, which forms a storage cavity 13. The end of the second inner shell 51 facing the cover 20 has a third opening 511, which can be used to insert or remove an oral container. The first inner shell assembly 30 is positioned over the third opening 511. This arrangement allows the first inner shell assembly 30 to seal the second inner shell 51 after the oral container in the second inner shell assembly 50 has been opened and used, reducing the risk of the oral container becoming damp or losing moisture after being opened and used.

[0045] In one embodiment, such as Figure 6As shown, the second inner shell assembly 50 also includes a removable sealing film 52, which covers the third opening 511. The sealing film 52 seals the oral contents within the second inner shell 51, isolating the oral contents from air before they are opened and used. This reduces the evaporation of water, fragrances, nicotine, and other active substances, thereby extending the shelf life. After the oral contents are opened and used, the sealing film 52 is at least partially removed, allowing the user to easily remove the oral contents.

[0046] In one embodiment, the material of the second inner shell 51 includes either polypropylene or polycarbonate. These materials are commonly used food-grade plastics and, being in direct contact with the food in the mouth, ensure the safety of the food.

[0047] In one embodiment, the sealing film 52 is made of one of aluminum foil, laminated aluminum foil, metallized film, or laminated composite material. These materials have excellent barrier properties, preventing moisture, air, and light, thereby maintaining the freshness and stability of the contents of the mouth.

[0048] In one embodiment, the base 10 and the cover 20 are made of either polypropylene or polycarbonate. These materials have good chemical resistance and impact resistance, and can withstand wear and tear during daily use, thereby extending the service life of the storage device 100.

[0049] When one part of the humidity retainer 40 includes a water-absorbing agent and the other part includes a slow-release agent, since the water-absorbing agent and the slow-release agent have opposite functions, if the water-absorbing agent and the slow-release agent do not correspond to the type of contents stored in the storage cavity 13, they will not be able to effectively prevent moisture and water loss. Please refer to [link / reference]. Figure 5 , Figure 7 , Figure 8 In one embodiment, a positioning member 11 is provided on the inner wall of the seat 10, a first positioning groove 512 is formed on the outer wall of the second inner shell 51 along the height direction, and a second positioning groove 314 communicating with the first positioning groove 512 is formed on the outer wall of the first inner shell 31 along the height direction. When the second inner shell assembly 50 and the first inner shell assembly 30 are assembled to the seat 10, the positioning member 11 slides into the second positioning groove 314 through the first positioning groove 512, so that each retainer receiving cavity 312 is respectively arranged adjacent to a storage cavity 13. The positioning member 11 can be a protrusion or a flange extending along the height direction. There can be one or more positioning members 11. When there are multiple positioning members 11, the size of each positioning member 11 can be different to prevent assembly errors. By setting the positioning member 11 and the positioning groove, assembly errors of the second inner shell assembly 50 and the first inner shell assembly 30 can be prevented, so that the absorbent and the slow-release agent correspond one-to-one with the type of oral contents stored in the storage cavity 13.

[0050] In one embodiment, such as Figure 8 As shown, the first positioning groove 512 is formed at the separation point between two adjacent storage cavities 13 of the second inner shell 51. By using the partition plate at the separation point between the two adjacent storage cavities 13 to set the first positioning groove 512, the thickness of the side wall of the second inner shell 51 can be reduced, thereby increasing the effective accommodating space of the second inner shell 51. Correspondingly, as Figure 5 As shown, the second positioning groove 314 can be opened at the separation of two adjacent retainer cavities 312 of the first inner shell 31. By using the partition plate at the separation of the two adjacent retainer cavities 312 to set the second positioning groove 314, the thickness of the side wall of the first inner shell 31 can be reduced, thereby increasing the effective accommodating space of the first inner shell 31.

[0051] This application provides a mouthpiece. Please refer to [link / reference]. Figure 9 The oral product 1000 includes an oral substance 300 and a storage device 100 as described above, wherein the oral substance is stored in the storage device 100. Storing the oral substance 300 in the storage device 100 can reduce the risk of the oral substance 300 becoming damp or losing moisture, thereby ensuring the consistency of the flavor of the oral substance 300 and improving the user experience.

[0052] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
