TECHNICAL FIELD

[0001] The utility model relates to the field of vacuum packaging box, specifically to a vacuum packaging box for mutton transportation. BACKGROUND

[0002] In the transportation process of mutton, it is crucial to maintain the freshness and quality of mutton. Traditional packaging methods often fail to meet the needs of long-distance transportation or long-term storage. Ordinary packaging cannot effectively isolate the effects of oxygen, microorganisms and other factors on mutton, which can lead to problems such as mutton spoilage, oxidation, color deterioration and loss of flavor.

[0003] With the development of cold chain logistics, although the low temperature environment slows down the decay rate of mutton to some extent, the sealing and gas barrier properties of the packaging are still key problems to be solved, so the vacuum packaging box for packaging in a vacuum environment has been developed. However, after transportation to the destination, the packaging inside is in a state of negative pressure in order to maintain the vacuum environment during transportation, which makes it difficult to open the packaging and may even damage the packaging or the mutton itself. The traditional solution is often cumbersome and requires the use of special tools or complex operation steps to break the seal of the packaging or balance the internal and external pressure, which not only increases the operation cost and time, but also may cause inconvenience to the secondary sale or processing of mutton. Therefore, we propose a vacuum packaging box for mutton transportation. SUMMARY

[0031] Structural description:

[0032] Shell 1:

[0033] The shape is a cuboid or other suitable solid shape for containing mutton. Its main function is to provide protection and carrying space for mutton. It is made of materials with certain strength and toughness, such as plastic or composite materials, to prevent damage from external forces such as impact and extrusion during transportation.

[0034] The top is designed with an opening for easy insertion of mutton. The opening edge is integrally formed with a shell frame protrusion 10, which surrounds the opening to form a specific mounting area for subsequent installation of sealing connection related components with the cover plate 2.

[0035] Cover plate 2:

[0036] The shape is adapted to the top opening of the shell 1 and can completely cover the opening. The material is matched with the shell 1 to ensure the consistency and stability of the overall package.

[0037] A mounting groove 12 is provided at the bottom, which is an important installation position of the blocking structure. The depth and shape design of the groove are matched with components such as the folding bag 13 in the blocking structure to ensure that the blocking structure can work normally in the groove and realize the sealing function. Through cooperation with the shell 1, the internal vacuum environment is maintained during transportation.

[0038] Hasp 3:

[0039] A common mechanical connecting device composed of movable fasteners and fixed buckles. It is usually made of metal or high-strength plastic materials, with sufficient strength and durability.

[0040] Distributed in the side of the shell 1 and cover plate 2, when the cover plate 2 is placed on the top of the shell 1 in the right place, by buckling the buckle 3, a certain pressure can be applied to make the shell 1 and the cover plate 2 tightly connected, effectively prevent the cover plate 2 from opening accidentally due to bumps and other reasons during transportation, ensure the integrity and sealing of the package.

[0041] Negative pressure connecting pipe 4:

[0042] Located at the top of the cover plate 2, it is a tubular structure, which is the key component to realize the connection between the shell 1 and the external vacuum equipment and the subsequent operation of releasing negative pressure.

[0043] It is internally provided with a plugging assembly, and the inner wall structure is unique. It has a tapered slope that gradually increases from top to bottom. This design is beneficial to the sealing or ventilation function of the plugging block structure at different positions. A stepped flared surface is also provided below the tapered slope. When the plugging block structure is located in the stepped flared surface area, a specific gap will be formed between the surface, allowing air to enter the closed space formed by the shell 1 and the cover plate 2.

[0044] Crossbar 5:

[0045] Made of metal or hard plastic material, it is horizontally fixed and installed inside the negative pressure connecting pipe 4.

[0046] Its main function is to provide stable support and precise positioning for the vertical support rod 6, ensuring that the vertical support rod 6 remains vertical and fixed in position inside the negative pressure connecting pipe 4, thereby providing reliable guidance and support for the upward and downward movement of the plugging block structure, ensuring the accuracy and stability of the overall operation of the plugging assembly.

[0047] Vertical support rod 6:

[0048] The material is usually compatible with the crossbar 5 to ensure the strength and durability of the overall structure. It is vertically installed on the crossbar 5, and its length is designed according to the internal dimensions of the negative pressure connecting pipe 4 to ensure that the plugging block structure can smoothly slide up and down on it.

[0049] As the sliding track of the plugging block structure, it guides the plugging top block 9 to move in a predetermined straight line direction when subjected to external force (such as pressing) or spring 8 elastic force, accurately controls the contact or separation of the plugging top block 9 with different parts of the inner wall of the negative pressure connecting pipe 4, and then realizes effective control of air intake and exhaust.

[0050] Limiting block 7:

[0051] Generally made of hard plastic or metal, there are two and they are firmly fixed and installed on the vertical support rod 6.

[0052] The upper and lower limiting blocks 7 are respectively located on the upper and lower sides of the plugging top block 9, and by limiting the sliding range of the plugging top block 9, the plugging top block 9 is prevented from moving excessively upward to be separated from the vertical support rod 6 under the elastic force of the spring 8 or from moving excessively downward to lose the connection with the vertical support rod 6 when pressed by a larger external force, so as to ensure that the plugging assembly can normally and stably work under various working conditions and maintain the sealing performance of the package.

[0053] The spring 8:

[0054] A metal spring with a proper elastic coefficient, such as a stainless steel spring, is selected to ensure the elastic stability and corrosion resistance of the spring during long-term use.

[0055] The spring 8 is sleeved on the vertical support rod 6 and is fixedly connected at one end with the limiting block 7 at the bottom and at the other end with the bottom of the plugging top block 9. In a normal state, the spring 8 is in an extended state and relies on the elastic force thereof to lift the plugging top block 9 upward, so that the side tapered surface of the plugging top block 9 is tightly fitted with the tapered surface of the inner wall of the negative pressure connecting pipe 4, thereby realizing sealing and preventing air from entering. When it is necessary to release the negative pressure, the plugging top block 9 is pressed by an external force, the spring 8 is compressed, the position of the plugging top block 9 is changed, and air can enter the space formed by the outer shell 1 and the cover plate 2. When the external force disappears, the spring 8 can restore to the original state and drive the plugging top block 9 to return to the sealing position again.

[0056] The plugging top block 9:

[0057] The plugging top block 9 is mostly composed of rubber or silicone and hard plastic or metal. The rubber or silicone part is used for tightly contacting the inner wall of the negative pressure connecting pipe 4 to realize sealing, and the hard part is used for connecting the spring 8 and stably sliding on the vertical support rod 6.

[0058] The side surface is designed as a tapered surface and is matched with the shape of the tapered surface of the inner wall of the negative pressure connecting pipe 4. Under the elastic force of the spring 8, the tapered surface can be tightly fitted with the tapered surface of the inner wall of the negative pressure connecting pipe 4 to form a reliable sealing surface and prevent air leakage. When pressed by a downward external force, the plugging top block 9 moves downward along the vertical support rod 6 to the stepped flared surface, at which time a gap is generated between the plugging top block 9 and the negative pressure connecting pipe 4, so that external air can enter the inside of the outer shell 1 and the cover plate 2 to change the internal pressure state.

[0059] The outer shell frame-shaped protrusion 10:

[0060] The outer shell frame-shaped protrusion 10 is a special structure at the opening edge of the top of the outer shell 1 and surrounds the opening in a frame shape. The material thereof is the same as that of the main body of the outer shell 1 and is manufactured by an integral molding process, and has high structural strength and stability.

[0061] The main function is to provide a stable installation base for the magnet 11, so that the magnet 11 can be accurately installed at a specific position, and when cooperating with the cover plate 2, it ensures that the magnet 11 can accurately correspond to the magnet 14 on the cover plate 2 for adsorption, thereby realizing the preliminary sealing and positioning of the connection part of the shell 1 and the cover plate 2, and providing good foundation conditions for the subsequent sealing structure (such as the folding bag 13) to play a sealing role.

[0062] Magnet 11:

[0063] A permanent magnet with a certain magnetic strength is selected, such as a neodymium iron boron magnet, to ensure that its adsorption force can meet the sealing requirements.

[0064] Fixedly installed on the shell frame-shaped protrusion 10, the top is provided with a triangular cross-section protrusion. When the cover plate 2 is closed with the shell 1, the magnet 11 and the magnet 14 in the bottom sealing structure of the cover plate 2 are adsorbed with each other, so that the cover plate 2 is tightly attached to the shell 1. At the same time, the triangular protrusion cooperates with the triangular groove at the bottom of the magnet 14, further increasing the tightness of adsorption and the sealing effect, effectively preventing air from entering the internal space from the connection part of the shell 1 and the cover plate 2.

[0065] Installation groove 12:

[0066] Located at the bottom of the cover plate 2, its shape is a groove that matches the sealing structure, and its depth and width are designed according to the size and movement range of the folding bag 13.

[0067] Made of the same material as the main body of the cover plate 2, it is formed by mechanical processing or mold forming process. The groove provides a stable installation space for the folding bag 13, so that the folding bag 13 can be fixed on the top inner wall, and under the action of the magnet adsorption force, it can smoothly stretch down to fill the gap between the shell 1 and the cover plate 2, realizing good sealing function and preventing air from entering the closed space formed by the shell 1 and the cover plate 2.

[0068] Folding bag 13:

[0069] Usually made of plastic film with good flexibility, air tightness and corrosion resistance, such as polyethylene or polyvinyl chloride film.

[0070] One end is fixedly installed on the top inner wall of the installation groove 12, and the other end is fixed with a magnet 14. When the cover plate 2 is closed with the shell 1, under the adsorption action of the magnet 11 and the magnet 14, the folding bag 13 is stretched and unfolded, extending out of the installation groove 12 and filling the gap between the shell 1 and the cover plate 2, forming a sealing barrier to effectively prevent air from entering, further enhancing the sealing performance of the entire package, and ensuring that the internal vacuum environment can be maintained for a long time during vacuum packaging.

[0071] Magnet two 14:

[0072] Magnet two 14 is also a permanent magnet, which is made of material matching with magnet one 11, such as neodymium iron boron magnet, so as to ensure sufficient adsorption force between magnet one 11 and magnet two 14.

[0073] Magnet two 14 is fixedly installed at one end of the folding bag 13 capable of retracting downward, and a groove with a triangular cross section is formed at the bottom of the folding bag 13 corresponding to the position of the top protrusion of magnet one 11. When the cover plate 2 is closed with the shell 1, magnet two 14 and magnet one 11 are attracted to each other, so that the folding bag 13 is unfolded to realize sealing, and meanwhile the triangular groove is tightly fitted with the triangular protrusion at the top of magnet one 11, further improving the stability of adsorption and the sealing effect, which plays a key auxiliary sealing role in the whole sealing structure of the package.

[0074] Working principle: in the vacuum operating chamber, the mutton to be transported is put into the shell 1, then the cover plate 2 is placed on the top of the shell 1 and fixed by the buckle 3, at this time the sealing structure is self-sealed to form a closed space, when transported to the designated position, the sealing structure is difficult to open due to the negative pressure link between the shell 1 and the cover plate 2, the plugging assembly is pressed, air is injected into the inside of the shell 1 again to reach normal pressure, then the buckle 3 is opened, and the shell 1 and the cover plate 2 are separated again.

[0075] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
