Description

Technical Field

[0001] This utility model relates to the technical field of packaging bags, specifically to a vacuum tea packaging bag that can be repeatedly opened and closed. Background Technology

[0002] Tea leaves are generally considered to be the leaves and buds of the tea tree, referring to the leaves of the evergreen shrub tea tree that can be used to make tea, as well as the beverage made from these leaves. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, pantothenic acid and other components that can improve human health. Tea is known as one of the world's three major beverages. Before being sold, tea is vacuum-sealed in packaging bags by factories to facilitate long-term storage.

[0003] According to Chinese patent number CN 218344169 U, a heat-insulating vacuum packaging bag for tea is disclosed, including a protective packaging bag with an inner wall of heat-insulating padding. The inner storage layer has multiple sets of dividing mechanisms, and the inner wall of the inner storage layer has slots corresponding to the number of dividing mechanisms for supporting them. The packaging bag has several sets of slots arranged longitudinally. Each set of slots can accommodate a storage layer with dimensions roughly matching the internal space of the inner storage layer, thus dividing the internal space of the inner storage layer into multiple sections. After the tea bag is torn open for use, the moisture-proof capability of the tea bag inside the packaging bag is improved. Simultaneously, the partitions provide support for the entire packaging bag, reducing damage to the tea bag caused by external factors.

[0004] The vacuum tea packaging bag described above uses partitions within the separating mechanism to divide the internal storage space, thus enabling separate storage of the tea leaves. However, once the tea bag is torn open, each divided cavity cannot form a sealed state, thus failing to achieve good moisture protection. Furthermore, while the perforated partitions facilitate the separation of broken tea leaves and improve the user experience, the resulting fragments tend to accumulate at the bottom, negatively impacting the user experience when using the tea leaves at the bottom. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the problem that the multiple cavities formed inside the existing vacuum packaging bags for storing tea, which are sealed to each other, are not convenient for long-term storage and use.

[0006] The technical solution adopted to solve the above technical problems is: A reusable vacuum tea packaging bag includes a bag body and a top opening. The inside of the bag body, near the opening, has a sealing strip for sealing the opening. The inside of the bag body forms a storage cavity with multiple elastic partitions arranged from bottom to top, dividing the storage cavity into multiple storage chambers. Each of the elastic partitions has a sealing structure to control the connection between adjacent storage chambers. The sealing effect of adjacent storage chambers does not affect each other, allowing for use as needed.

[0007] As a preferred technical solution of this utility model, the sealing structure is a tear opening set on the top of the elastic partition. The tear opening between adjacent storage compartments is to achieve communication. The top of the tear opening is provided with a matching sealant, and its edge is pasted on the top of the elastic partition. The top of the sealant is provided with a tear strip.

[0008] As a preferred technical solution of this utility model, the outer side of the storage cavity is provided with multiple cavities, which are not interconnected with each other. The bottom sides of the multiple storage chambers are provided with flush guide ports, which are respectively connected to the corresponding cavities. The generated debris can slide into the corresponding cavity for storage.

[0009] As a preferred technical solution of this utility model, an elastic partition is provided between adjacent cavities for isolation, and the elastic partition has a supporting effect on the overall shape of the bag.

[0010] As a preferred technical solution of this utility model, the top of the multiple sealing structures is raised as a whole, making it easier for the generated tea leaves to slide into the cavity for collection.

[0011] As a preferred technical solution of this utility model, a support frame is provided below the inner wall of the cavity at the bottom, which supports the bottom of the entire storage cavity and is not easily deformed.

[0012] As a preferred technical solution of this utility model, a tear opening is provided on one side of the bag opening, and a pressure strip corresponding to the sealing strip is provided on the upper side of the outer wall of the bag body. Pressing the pressure strips on both sides makes it easier to control the sealing strip. Both pressure strips on both sides are connected to the bag body through a connecting part.

[0013] The beneficial effects of this utility model are as follows: This invention effectively solves the problem of traditional vacuum packaging bags' internal compartments not being able to be individually sealed, thus affecting the long-term moisture-proof and freshness preservation of tea, by setting up independently sealed storage chambers and controllable communication structures. Specifically, the bag body is divided into multiple independent storage chambers by multiple elastic partitions. Each elastic partition has a sealing structure consisting of a tear and a sealing tape at the top. Each storage chamber is initially kept independently vacuum sealed and does not affect the others. When it is necessary to take out the tea from the lower layer, the user only needs to lift the sealing tape and tear the tear to connect the storage chamber with the opened chamber above, while the other unopened storage chambers remain completely sealed. This design achieves true "open on demand," minimizing the number of times and the time that the remaining tea comes into contact with air, and significantly improving the long-term moisture-proof and freshness preservation effect of the tea.

[0014] This utility model innovatively integrates a tea residue collection cavity with an overall support structure, which effectively separates tea residue to improve the user experience while ensuring the structural stability of the packaging bag. Multiple independent cavities that are not interconnected are provided on the outside of the storage cavity and are connected to the bottom of each storage chamber through a feed inlet. Tea residue can be automatically slid into the corresponding cavity through the feed inlet for centralized storage, thereby avoiding the residue from being mixed with whole tea leaves and affecting the brewing quality. In addition, the elastic partitions between the cavities and the support frame in the bottom cavity together form a sturdy support frame, which greatly enhances the compression resistance of the entire packaging bag, making it less prone to deformation during storage and transportation, effectively protecting the tea inside from physical compression damage, and taking into account both functionality and structural reliability.

[0022] Example 1 exist Figures 1-3This utility model provides a technical solution: a reusable vacuum tea packaging bag, comprising a bag body 1 and a top opening 2. A sealing strip 11 is provided inside the bag body 1 near the opening 2 for sealing the opening. Typically, two sealing strips 11 are interlocked to achieve a seal inside the bag body 1. A storage cavity is formed inside the bag body 1, with multiple elastic partitions 3 arranged from bottom to top, dividing the cavity into multiple storage chambers. Each elastic partition 3 has a sealing structure controlling the connection between adjacent storage chambers. The sealing effect of adjacent storage chambers does not affect each other, ensuring that each storage chamber containing tea is sealed. When the tea in the upper storage chamber is used up, the tea in the lower storage chamber is opened for use, thus achieving on-demand use. Specifically, the sealing structure consists of a tear 4 at the top of the elastic partition 3. Tearing open the tear 4 connects the adjacent storage compartments, allowing access to the tea leaves inside. All tea leaves are accessed through the bag opening 2. A matching sealing adhesive 5 is located at the top of the tear 4, with its edges attached to the top of the elastic partition 3. Each sealing adhesive 5 has a tear strip 6 at its top. To use the tea leaves, first tear open the top bag opening, then pull open the sealing strip 11. This allows access to the tea leaves in the topmost storage compartment. Before using the tea leaves below, first tear open the sealing adhesive 5 on the tear 4, then tear open the tear 4 again to open the lower storage compartment. This separates the tea leaves for storage while improving their long-term usability.

[0023] In one aspect of this embodiment, multiple cavities 8 are provided on the outside of the storage chamber, and the multiple cavities 8 are not interconnected. The bottom of the multiple storage chambers is provided with flush guide ports 7 on both sides, which are respectively connected to the corresponding cavities 8. This allows the tea leaves inside the bag 1 to slide into the corresponding cavities 8 for separate storage due to external forces, thereby improving the user experience.

[0024] In one aspect of this embodiment, an elastic partition 9 is provided between adjacent cavities 8 for isolation. Under the action of the elastic partition 9, it provides support for the overall shape of the bag body 1, making the shape of the bag body 1 less prone to deformation and preventing the tea leaves inside from being crushed by external force.

[0025] In one aspect of this embodiment, it should be noted that the tops of the multiple sealing structures are generally raised, making it easier for the generated tea leaves to slide into the cavity 8 for collection.

[0026] In one aspect of this embodiment, a support frame 10 is provided below the inner wall of the bottom cavity 8 to support the bottom of the entire storage cavity, making it less prone to deformation and easier to place upright during storage.

[0027] In one aspect of this embodiment, a tear 14 is provided on one side of the bag opening 2, and a pressure strip 12 corresponding to the sealing strip 11 is provided on the upper side of the outer wall of the bag body 1. Pressing the pressure strips 12 on both sides makes it easier to control the sealing strip 11 to seal. Both pressure strips 12 are connected to the bag body 1 through the connecting part 13. When sealing, by pressing the pressure strips 12 on both sides at the same time, the corresponding sealing strips 11 are driven to engage with each other to achieve sealing. It should be noted that the connecting part 13 can be a harmless and biodegradable adhesive to bond the pressure strip 12 to the outside of the bag body 1.

[0028] The reusable vacuum tea packaging bag of this utility model operates as follows: Upon initial use, the user opens the bag through the pre-set tear 14 on one side of the bag opening 2, and then presses the two pressure strips 12 on the upper part of the outer wall of the bag body 1 towards the middle. Using leverage, the corresponding sealing strips 11 disengage, thus opening the bag opening 2. At this time, only the uppermost storage compartment is opened, allowing the user to access the tea inside. The elastic partition 3 at the bottom of this storage compartment and its sealing structure (through the tear 14) are also open. 4. The sealing tape 5 and the tear strip 6 on top remain intact, ensuring that each storage compartment below is in an independent vacuum-sealed state. When you need to take out the tea in the lower layer, you need to first tear open the tear strip 6 at the bottom of the currently opened storage compartment, peel off the sealing tape 5, and expose the tear 4. Then tear open the tear 4 to connect the two adjacent storage compartments, and you can take out the tea in the newly exposed storage compartment. This process can be repeated layer by layer, truly realizing opening as needed and maximizing the sealing and moisture protection of unused tea. Throughout the entire process, tea leaves generated during handling or retrieval will slide through the guide ports 7 located on both sides of the bottom of each storage compartment into the corresponding independent cavity 8 on the outside of the storage chamber for collection, thus preventing the tea leaves from contaminating the whole leaf. The cavities 8 are separated and supported by elastic partitions 9, which, together with the support frame 10 located in the bottom cavity 8, maintain the overall shape of the bag 1, resist pressure and prevent deformation, and ensure the safety of the tea leaves inside during storage and transportation. After use, the user can press the pressure strips 12 on both sides to make the sealing strip 11 tightly lock, thereby resealing the bag opening 2, realizing repeated opening and closing of the packaging bag and long-term preservation.
