Description

Technical Field

[0001] This utility model belongs to the field of glass bottle packaging technology, and relates to a glass bottle packaging structure with cushioning and protection function. Background Technology

[0002] In numerous industries such as food, pharmaceuticals, and cosmetics, glass bottles have become an important packaging medium for liquids, semi-solids, and fragile solids due to their advantages such as strong chemical stability, good barrier properties, and recyclability. To ensure the safety of glass bottles during storage, transportation, and handling, and to prevent bottle breakage or leakage due to vibration or impact, the cushioning and protective performance of the packaging structure has become a core consideration in the product circulation process. At the same time, the efficiency of packaging assembly and disassembly, as well as its reusability, directly affect the logistics costs and environmental benefits of enterprises. Therefore, the demand for packaging structures that combine cushioning and protection, ease of operation, and recyclability is becoming increasingly urgent.

[0003] However, in actual production and use, existing glass bottle packaging structures still have many prominent problems. On the one hand, the cushioning and protection are not targeted or comprehensive enough. Most packaging only provides simple support for the bottom or top of the glass bottle, lacking lateral cushioning protection for the bottle body. When handled multiple times or accidentally dropped, the bottle body is prone to breakage due to concentrated force. On the other hand, the disassembly and handling efficiency is low. Traditional packaging often adopts a single independent cushioning chamber design, requiring manual handling of glass bottles one by one, which is difficult to meet the production needs of batch loading and unloading. In addition, some cushioning structures are made of one-time molded foam or paper parts, which are scrapped after use, not only causing resource waste but also increasing the cost of packaging waste disposal, which is not in line with the development trend of green production.

[0004] After reviewing relevant materials, the main solutions to the above problems currently fall into two categories: optimization of cushioning structures and improvement of packaging forms. Among them, patent CN216444196U, titled "A Glass Bottle Packaging Box with Cushioning Function," proposes a sliding cushioning liner inside the box. Multiple liner rings and foldable cushioning rails form a surrounding cushioning support between the box and the bottle. The principle is to increase the contact area with the bottle by utilizing the triangular structure of the folded rails, thus improving the cushioning effect. This solution effectively solves the problem of insufficient bottle protection and demonstrates good cushioning performance in small- to medium-batch transportation. Other solutions use cushioning materials such as pearl cotton and air column bags to wrap the glass bottle for protection, absorbing impact energy through the elastic deformation of the materials themselves. However, the existing methods still have obvious limitations: the paper cushioning liner used in the above solutions has limited strength and is prone to creases and breakage after repeated use, making it difficult to achieve long-term reuse. In addition, each package is only suitable for a small number of glass bottles, and each bottle still needs to be handled individually when taking out or putting in batches. Although the wrapping protection such as pearl cotton has a stable cushioning effect, the packaging process is time-consuming and labor-intensive, and the material recycling rate is low, which will increase the cost of enterprises in the long term.

[0005] Based on a comprehensive analysis of the advantages and disadvantages of existing technologies, this utility model aims to provide a packaging solution that combines inner and outer boxes, features a detachable fixing structure, and incorporates airbag limiting components. This solution addresses the problems of incomplete protection, low disassembly and assembly efficiency, and poor reusability of existing structures, thereby meeting the dual needs of industrial production and green logistics. Utility Model Content

[0006] This utility model provides a glass bottle packaging structure with cushioning and protection function, which can effectively cushion and protect glass bottles, facilitate batch handling, and is reusable.

[0007] To solve the above problems, the technical solution adopted by the utility model is as follows: A glass bottle packaging structure with cushioning and protection function is characterized by comprising an outer box and an inner box; the inner box is movably disposed inside the outer box, with openings at both its upper and lower ends, and multiple through holes along the height direction on the side wall of the inner box; a detachable base is provided at the bottom of the box, and connectors corresponding to the through holes are fixedly connected to the base; the end of the connector away from the base passes through the through hole and extends to the top of the inner box, and a fixing hole is provided on the connector; multiple locking ports are provided near the port of the inner box, and the fixing holes on the connectors correspond to the locking holes; a limiting member is provided at the locking port of the inner box and is connected to the fixing hole and the locking hole; the limiting member is an airbag structure, respectively provided at the bottom and top of the inner box, and an inflation hole is provided on the limiting member.

[0008] The principle and advantages of this scheme are as follows: This solution achieves both protection and ease of use for glass bottles through a collaborative design of "nested inner and outer casings + detachable fixing structure + airbag limiting and buffering." Its core principle revolves around the logic of "positioning – buffering – fixing – convenient operation." The outer casing, as the outer protective frame, provides rigid support for the overall structure, while the inner casing, as the direct load-bearing unit for the glass bottle, is movably installed inside the outer casing to form a double-layer protective structure, reducing the direct impact of external shocks on the inner bottle. Regarding fixing and limiting, the detachable base of the inner casing is precisely assembled with the inner casing via connectors: the connectors on the base pass through the through-holes in the side wall of the inner casing and extend to the top. With the cooperation of the limiting components, the fixing holes on the connectors, and the locking holes in the inner casing, a stable vertical fixation is formed, ensuring the reliability of the connection between the base and the inner casing and preventing the base from shifting during transportation, which could cause the bottle to become unbalanced. The cushioning and protection function is mainly achieved by the limiting components of the airbag structure. After the limiting components at the bottom and top of the inner box are inflated through the inflation port, they can fit tightly against the bottom and top surfaces of the glass bottle. The elastic deformation of the gas inside the airbag absorbs the vibration and impact energy during transportation, while also forming a vertical limit on the bottle to prevent it from moving up and down. The nested structure of the inner and outer boxes further blocks lateral impacts, forming all-round cushioning protection. During loading and unloading operations, it is only necessary to remove the limiting components to release the fixing of the connecting parts, and the inner box along with the bottom support can be taken out as a whole. Then, the air is released through the inflation port to detach the limiting components from the bottle, realizing the batch loading and unloading of glass bottles. The entire process does not require handling each bottle individually.

[0009] Compared to existing technologies, which use folded grids in a paper-based cushioning liner to form a surrounding support, the paper structure has limited cushioning strength and is susceptible to humidity and repeated use. In contrast, the airbag limiting component used in this solution can be adapted to glass bottles of different heights and diameters by adjusting the inflation volume. Furthermore, the elastic cushioning characteristics of the airbag are superior to those of the paper grid in absorbing high-frequency vibrations. For example, during long-distance transportation, when facing continuous bumpy road conditions, the airbag can continuously dissipate the impact force through gas flow, reducing the amplitude of force fluctuations on the bottle body compared to the paper cushioning structure. This completely avoids the problem of bottle breakage caused by localized force concentration in existing technologies. Regarding batch handling efficiency, existing technologies, whether using paper cushioning liners or pearl cotton wrapping, require fixing or disassembling each bottle individually. Taking a 10-bottle pack as an example, a single handling process typically takes more than 5 minutes. This solution, however, utilizes a holistic disassembly and assembly system with rapid airbag deflation. Only three steps are needed: removing the limiting components, lifting the inner box, and opening the inflation port. This allows for the batch handling of 10 or more glass bottles within 1 minute, improving operational efficiency by over 80%. This is particularly suitable for industrial batch handling scenarios such as food processing plants and pharmaceutical companies. In terms of reusability, existing paper cushioning liners show creases and breakage after 3-5 disassemblys and assemblys, and pearl cotton wrappings are prone to elasticity loss with long-term use. In contrast, this solution uses rigid plastic or metal for the outer and inner boxes, with rigid connectors and limiting components. The airbag limiting components can be repeatedly inflated and deflated. The entire structure can be reused while maintaining its original protective performance. The cost per use is lower than existing paper packaging, while also reducing packaging waste. In addition, existing technologies are mostly designed with fixed sizes, and changing the size of the glass bottle requires custom packaging. However, this solution can adapt to various glass bottles with diameters of 5-15cm and heights of 10-30cm by adjusting the inflation volume of the airbag and the position of the base. There is no need to design different sizes of packaging, which greatly reduces the inventory and customization costs of enterprises.

[0010] Furthermore, a cushioning element is filled between the inner wall of the outer box and the outer wall of the inner box. This cushioning element is one of pearl cotton, EPS foam, or air column bags. Filling the space between the inner and outer walls of the outer and inner boxes with this cushioning element, together with the airbag restraints inside the inner box, forms a double-layered cushioning protection system, enhancing the overall impact resistance of the packaging structure. External impacts first act on the outer box. The cushioning element can preferentially absorb and dissipate most of the impact energy through its own elastic deformation or gas compression. If the packaging structure is accidentally collided or dropped during transportation, the cushioning element can effectively weaken the transmission of impact force inward, preventing the inner box from directly bearing severe external force. Simultaneously, this cushioning element can fill the gap between the inner and outer boxes, limiting the lateral swaying of the inner box within the outer box. Combined with the vertical restraint of the bottle by the airbags inside the inner box, it forms all-around protection against lateral swaying and vertical fixation of the glass bottle, solving the problem of blind spots caused by relying on only a single cushioning structure in existing technologies. Pearl cotton and EPS foam offer advantages such as lightweight, low cost, and easy processing, while air column bags allow for adjustable cushioning strength through inflation. All three materials are suitable for different scenarios and can form a reasonable combination of soft cushioning and hard support with the rigid structure of the inner and outer boxes. This ensures cushioning effectiveness without excessive packaging volume due to excessively thick cushioning materials, balancing protective performance and space utilization. Furthermore, these cushioning components can be installed and removed simultaneously with the inner and outer boxes. Pearl cotton and air column bags are reusable, while EPS foam, although a disposable material, is extremely low in cost. The overall design enhances comprehensive protection while also considering practicality and economy.

[0011] Furthermore, the limiting component is a T-shaped pin, which connects with the fixing hole and the locking hole. Setting the limiting component as a T-shaped pin and connecting it with the fixing hole and locking hole ensures connection stability while improving the ease of assembly and disassembly of the packaging structure and operational efficiency, meeting the core needs of batch handling. The rod of the T-shaped pin can precisely pass through the aligned fixing hole and locking hole, and its lateral protrusion forms a reliable axial limit, effectively preventing displacement of the connecting component during transportation vibration, avoiding loosening of the connection between the base and the inner box, achieving stable fixation without rotation or tightening, and can withstand vertical tensile and shear forces, ensuring the structural reliability of the inner box and bottle as a whole when picked up. The insertion and removal of the T-pin requires no tools and can be completed with one hand. In batch handling scenarios, operators only need to quickly pull out the T-pin to release the connector and directly lift the inner box from the outer box. Compared to existing technologies that require disassembling bolts or clips one by one, the disassembly and assembly time for a single package can be reduced to 1 / 3. Furthermore, the T-pin's simple structure and high rigidity make it resistant to damage from repeated insertion and removal, allowing for long-term reuse along with the inner and outer boxes, avoiding the problems of easy wear and frequent replacement required by some existing limiting structures. In addition, the T-pin's head design provides a clear indication of proper engagement; when the pin head is flush with the inner box side wall, the connection is confirmed, reducing operational errors and further improving operational standardization during production and turnover.

[0012] Furthermore, the sealing element is an elastic rubber ring with an inverted trapezoidal cross-section. The groove on the outer casing matches the shape of the rubber ring. When the sealing cap is closed, the inclined sidewall of the inverted trapezoidal rubber ring forms a tight contact surface with the inner wall of the groove. As the sealing cap is pressed down, the rubber ring undergoes elastic deformation under pressure. The reaction force generated by the deformation continuously increases the pressure between the contact surfaces, thus forming a multi-directional sealing barrier. Compared with ordinary rectangular cross-section seals, the inverted trapezoidal structure effectively reduces the sealing gap, especially providing better protection against dust, moisture, and other minute impurities, preventing the glass bottle label from becoming blurred due to moisture or the bottle from becoming stained. The inverted trapezoidal shape, wider at the top and narrower at the bottom, forms a mortise-and-tenon-like fit with the groove. After the sealing cap is closed, the rubber ring is not easily dislodged from the groove. Even if it encounters bumps and vibrations during transportation, the sealing structure can remain intact, solving the problem of some existing seals easily shifting and causing sealing failure. From an operational and practical standpoint, the deformation characteristics of the elastic rubber ring reduce the difficulty of alignment during capping. It can be easily inserted into the groove without precise alignment, and the inverted trapezoidal structure facilitates the opening and closing of the sealing cap. It avoids being difficult to open due to excessive tightness, and also prevents the sealing effect from being compromised due to a loose fit. In addition, the rubber material has good aging resistance and reusability, maintaining its elasticity after multiple openings and closings. It can be used repeatedly in tandem with the main packaging body for a long period of time, balancing sealing reliability and economy.

[0013] Furthermore, the inner wall of the inner box is lined with a fiber layer, which is made of non-woven fabric or needle-punched cotton. The fiber layer is fitted to the limiting component. When an external impact is transmitted to the inner box through the outer box and the buffer component, the fiber structure of the non-woven fabric or needle-punched cotton can first dissipate part of the impact force through its own looseness. Combined with the elastic buffering of the airbag limiting component, compared with the single buffering method that relies solely on the airbag, the instantaneous impact force on the bottle can be further reduced. At the same time, the fiber layer is soft and has a delicate surface, which can directly adhere to the glass bottle body and avoid scratching the bottle body caused by hard contact between the airbag after inflation. Especially for glass bottles with printed labels or glaze, it can effectively protect the surface decorative layer from peeling off and wear, solving the problem that existing buffering structures are prone to causing damage to the appearance of the bottle. Both non-woven fabric and needle-punched cotton are lightweight, breathable, and bend-resistant. They can closely conform to the shape of the inner wall of the box and deform synchronously with the inflation of the airbag limiting component, ensuring the compatibility of the protective structure with the bottle. Moreover, both materials are inexpensive, reusable, and can form a long-term recyclable whole with the main packaging. Furthermore, the fiber layer can absorb tiny debris that may be generated during transportation, preventing impurities from entering between the airbag and the bottle and causing frictional damage, further enhancing the comprehensiveness of protection. The combination of the fiber layer and the airbag not only makes up for the shortcomings of single airbag protection in terms of surface protection.

[0014] Furthermore, a sealing plug is provided on the inflation port. The sealing plug is interference-fitted with the inflation port, meaning that the size of the sealing plug is slightly larger than the diameter of the inflation port. After being inserted, the sealing plug will form a tight fit with the inner wall of the inflation port due to elastic deformation, completely blocking the flow of gas inside the airbag to the outside. Compared with ordinary clearance-fit sealing structures, this design can effectively avoid gas leakage caused by vibration and bumps during transportation, ensuring that the airbag always maintains sufficient air pressure to achieve stable positioning and buffer protection for the glass bottle. Moreover, the interference-fit sealing plug can be inserted and removed without the need for tools: when inflating, simply pull out the sealing plug manually, and after inflation, press it back into the inflation port to achieve a seal. The operation is simple and efficient, especially suitable for industrial batch inflation scenarios. At the same time, the tight fit of the sealing plug can also prevent dust, moisture and other impurities from entering the inflation port and the inside of the airbag, avoiding impurities from clogging the inflation port or abrading the inner wall of the airbag, thus extending the service life of the airbag. The friction generated by the interference fit allows the sealing plug to maintain a stable installation state even after long-term use or frequent insertion and removal. Unlike threaded seals, it will not slip and fail, nor will it suffer from a decrease in fit due to aging like rubber plugs. It can be reused for a long time in sync with the airbag, taking into account both the durability of the seal and the economy of use.

[0015] Furthermore, both the edge of the sealing cap and the upper edge of the outer box are equipped with matching Velcro straps. The Velcro straps, through the tight fit between the nylon hooks and the fleece, firmly fix the sealing cap to the upper edge of the outer box, further enhancing the stability of the sealing structure. Even if the packaging is tilted or vibrated during transportation, the adhesive force of the Velcro straps can prevent the sealing cap from loosening and avoid gaps between the rubber ring and the groove, which could lead to sealing failure. Compared with sealing methods that rely solely on mechanical fastening, the double sealing design significantly improves the barrier effect against dust and moisture, effectively protecting the glass bottle and its contents from the influence of the external environment. From an operational and practical perspective, Velcro allows for opening and closing without any tools, enabling quick and easy application and removal with just one hand. Compared to threaded connections and snap-locking structures, this significantly reduces the difficulty of opening and closing the sealing cap. In mass production scenarios, operators can quickly lift the sealing cap to remove the inner box, or close it and quickly secure it with Velcro. The sealing operation time for a single package is shorter than that of traditional snap-locking structures. Furthermore, the adhesive strength of Velcro remains stable even after multiple openings and closings, unlike snaps which wear and break with frequent use, allowing for long-term reuse in sync with the packaging body. In addition, the flexible bonding characteristics of Velcro can accommodate minor dimensional deviations between the sealing cap and the outer box. Even with slight errors during processing, a tight fit can still be achieved through the deformation of the Velcro, reducing the precision requirements of production and balancing sealing reliability with production economy.

[0016] Furthermore, the upper port of the outer casing has a groove, and the lower surface of the sealing cap has a sealing element that matches the groove. The matching design of the groove and the sealing element enables precise positioning of the sealing cap and the outer casing. When the cap is closed, the sealing element can quickly embed into the groove, avoiding sealing failure due to misalignment. At the same time, the groove provides circumferential restraint for the sealing element, preventing it from shifting during transportation vibrations and ensuring the stability of the sealing structure. The matching concave-convex structure allows the sealing element to form a tight fit with the inner wall of the groove. Combined with the elastic deformation of the sealing element itself, it can effectively block external dust, moisture, and other impurities from entering the packaging. Compared with flat-fit sealing, this structure can significantly reduce sealing gaps, especially in humid environments or long-distance transportation, preventing glass bottle labels from becoming blurred by moisture, the bottle body from becoming stained, and even preventing the contents from being contaminated due to poor sealing. From a practical compatibility perspective, the combination design of the groove and the seal has strong compatibility and can work synergistically with auxiliary fixing structures such as Velcro. The seal is responsible for physical barrier, while the Velcro is responsible for strengthening the fixation. The combination of the two ensures the reliability of the seal and simplifies the opening and closing operation. At the same time, this structure is easy to process. The groove can be integrally processed when the outer casing is formed, and the seal can be easily installed by means of bonding. It is also easy to replace separately after wear, without having to replace the entire sealing cover or outer casing, thus balancing protective performance and economic use.

[0017] Furthermore, the limiting component is detachably located near the top between the outer and inner boxes. This top-positioning directly restricts the vertical movement and lateral shift of the inner box within the outer box. Even during transport, if bumps or tilting occur, the limiting component firmly secures the inner box to its predetermined position on the outer box by abutting against the force-bearing surfaces of the inner and outer boxes, preventing violent collisions with the inner wall of the outer box. Combined with the bottom support structure, this forms a two-way stabilizing system of top limiting and bottom support, solving the problem of some existing packages relying solely on bottom fixation, which causes the top of the inner box to wobble. From an operational convenience perspective, the detachable design and the top-positioning offer synergistic advantages. Operators do not need to penetrate deep into the packaging; the limiting component can be installed and removed from the top of the box. Especially in batch handling scenarios, the limiting component can be quickly removed after opening the sealing cover, allowing the inner box to be lifted directly from the outer box as a whole. Compared to structures with limiting components located in the middle or bottom, this reduces the number of steps and greatly improves loading and unloading efficiency. Attached Figure Description

[0020] The reference numerals in the accompanying drawings include: outer casing 1, limiting component 2, sealing cover 3, Velcro 4, base 5, through hole 6, connector 7, fixing hole 8, limiting and fixing component 9, buffer component 10, limiting component 11, inflation hole 12, inner casing 13, groove 14, sealing component 15, fiber layer 16. Example 1 is basically as follows Figure 1-2 As shown, a glass bottle packaging structure with cushioning and protection function includes an outer box 1 and an inner box 13. The outer box 1 is made of rigid PP plastic through one-piece injection molding, and has an overall rectangular structure with a length of 40cm × width of 30cm × height of 35cm. An annular groove 14 is opened on the upper edge of the outer box 1, with an inverted trapezoidal cross-section, 1.5cm wide × 1cm deep. A sealing element 15, an elastic rubber ring with an inverted trapezoidal cross-section that matches the groove 14, is embedded in the groove 14. The sealing element has a Shore hardness of 60HA. A nylon hook and loop fastener 4 is sewn along the outer side of the outer box 1. The sealing cap 3 is made of PP plastic with a thickness of 3mm. The lower surface of the sealing cap is correspondingly sewn with a fleece strip of the hook and loop fastener 4. When the sealing cap 3 is closed, the hook and loop fastener 4 fits tightly, and the sealing element 15 is completely embedded in the groove 14 to form a double seal.

[0021] The inner box 13 is made of ABS engineering plastic, with dimensions of 38cm (length) × 28cm (width) × 32cm (height). It is open at both the top and bottom. Eight through holes 6, each 1cm in diameter, are evenly distributed along the height of the side walls, with two symmetrically distributed on each side. A cushioning element 10, made of pearl cotton, is filled between the inner wall of the outer box 1 and the outer wall of the inner box 13. The cushioning element 10 is 1cm thick and has a density of [missing information]. The inner box 13 is bonded and fixed to the inner wall of the outer box 1 and the outer wall of the inner box 13 respectively with double-sided adhesive. After filling, the inner box 13 has no lateral shaking space inside the outer box 1.

[0022] The bottom of the inner box 13 is equipped with a detachable base 5 made of PP plastic with a thickness of 2cm. Eight connectors 7, each corresponding to a through hole 6, are welded to the upper surface of the base 5. The end of each connector 7 away from the base 5 passes through the through hole 6 and extends to 5cm from the top of the inner box 13. Each connector 7 has a fixing hole 8 near the top. The side wall of the inner box 13 near the top has a locking hole corresponding to the fixing hole 8. The limiting member 2 is a T-shaped pin made of ABS plastic with a rod diameter of 0.48cm × length of 3cm and a head diameter of 1.5cm. The T-shaped pin passes through the aligned fixing hole 8 and locking hole to fix the base 5 to the inner box 13.

[0023] The inner casing 13 has limiting members 11 at both the bottom and top. These limiting members 11 are PVC airbag structures. The bottom limiting member 11 can be placed directly on the bottom of the inner casing 13, while the top limiting member 11 is an independent airbag structure with no snap-fit ​​connection at the edges. An inflation hole 12 is pre-drilled on the limiting member 11. The inflation hole 12 has a diameter of 0.6 cm, and a sealing plug made of rubber with a diameter of 0.65 cm is embedded inside the inflation hole 12, providing an interference fit. The inner wall of the inner casing 13 is lined with a fiber layer 16. The fiber layer 16 is made of needle-punched cotton and is 0.5 cm thick. It is bonded to the inner wall of the inner casing 13 with hot melt adhesive, and the fiber layer 16 is tightly fitted to the limiting members 11.

[0024] The workflow of this embodiment is as follows: Packaging preparation (packing stage): Remove the outer box 1 and place the inner box 13, which is filled with the cushioning element 10, into the outer box 1, ensuring that the bottom of the inner box 13 fits snugly against the bottom of the outer box 1.

[0025] Place the airbag of the bottom limiting component 11 at the bottom of the inner box 13, remove the sealing plug on the inflation hole 12, inflate the airbag with the air pump at an inflation pressure of 0.1 MPa, so that the airbag inflates and fits tightly against the bottom of the inner box 13 and the fiber layer 16, and insert the sealing plug to complete the seal. At this time, the bottom airbag plays a pre-fixing role for the glass bottles placed later.

[0026] Glass bottle loading: Place glass jars, such as jam jars with a diameter of 8cm and a height of 20cm, one by one into the inner box 13. The bottom of the glass jar is tightly fitted to the bottom limiting piece 11. With the support and elastic fixation of the bottom airbag, the glass jar is prevented from tipping over when placed.

[0027] After all the glass bottles are placed, take the top limiting piece 11 and place it on top of the inner box 13 so that it covers the top surface of the glass bottle. Inflate the top airbag with an inflation pressure of 0.08 MPa until the airbag is in contact with the top of the glass bottle and the inner wall of the top of the inner box 13. Insert the sealing plug to complete the limiting.

[0028] Push the base 5 so that the connector 7 passes through the through hole 6 of the inner box 13. When the fixing hole 8 of the connector 7 is aligned with the locking hole of the inner box 13, insert the T-shaped pin to fix the base 5 to the inner box 13. Place the inner box as a whole into the outer box. After setting a limiting piece near the port between the inner box and the outer box for limiting and fixing, close the sealing cover 3 and press the Velcro 4 to make it fit tightly to complete the overall packaging.

[0029] Transportation protection: During transportation, external impacts are initially dissipated by the outer casing 1 and the buffer 10. The bottom and top limiting components 11 absorb vibration energy through the elastic deformation of the airbags. The fiber layer 16 prevents the glass bottle from making hard contact with the inner casing 13. Multiple protections ensure the bottle remains intact.

[0030] Remove the glass bottle: Open the Velcro 4 and the sealing cover 3, first remove the limiting piece 2 between the outer box 1 and the inner box 13, and lift the inner box 13 upwards until the connector 7 exposes the top of the outer box 1.

[0031] Pull out the T-pin on the connector 7 to release the fixation between the bottom support 5 and the inner box 13, and continue to lift the inner box 13 completely upwards to lift the outer box 1.

[0032] Pull out the sealing plugs of the bottom and top limiting parts 11 and the air holes 12 in sequence, slowly release the gas in the air bag, and after the air bag is completely deflated, it will detach from the surface of the glass bottle, and the glass bottles can be removed in batches; the inner box 13, the bottom support 5 and the limiting parts 11 can be reused, and only the damaged buffer part 10 or the air bag needs to be replaced.
