Description

Technical Field

[0001] The invention belongs to the technical field of meat product packaging boxes, in particular to a meat product vacuum fresh-keeping packaging box. Background Art

[0002] Meat products are foods made from meat as the main raw material. There are many types, such as fresh meat, cured meat, ham, sausage, etc. In order to maintain the freshness of meat products, they are usually stored or transported in fresh-keeping packaging boxes. At present, the fresh-keeping technology has gradually evolved into vacuum fresh-keeping boxes. The air inside the sealed box is extracted by a vacuum pump, which greatly reduces the phenomenon of meat products deteriorating due to bacterial growth, thereby extending the shelf life of meat products.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 7 As shown, a meat product vacuum fresh-keeping packaging box according to the present invention comprises a box body 1 and a cover body 2;

[0034] The box body 1 is fixedly connected with an inner liner 3; a group of partitions 4 are evenly distributed inside the inner liner 3; a group of compartments 5 are formed between the inner liner 3 and the partitions 4; the inner liner 3 and the partitions 4 are both provided with interconnected cavities 6; a water-absorbing layer 7 is fixedly connected inside the cavity 6, and the material of the water-absorbing layer 7 can be sponge, foam, fluffy cloth, etc.; a group of adsorption holes 8 are evenly distributed on the inner wall surface of the compartment 5, and the adsorption holes 8 are connected with the cavity 6;

[0035] The cover body 2 is arranged on the upper side of the box body 1; a suction port 9 is arranged on the surface of the cover body 2, and a sealing cover is arranged on the outer end of the suction port 9; a fixing component such as a buckle, an elastic buckle, a screw, etc. is arranged between the cover body 2 and the box body 1.

[0036] The meat product storage container in the prior art usually places a large number of meat products inside the box 1. During transportation, the container is shaken by the transport vehicle, so the meat products will constantly collide inside the container, affecting the appearance and taste of the meat products. Moreover, if the refrigeration conditions change during transportation and the temperature rises, the frozen meat products will gradually melt, thereby accumulating water inside the container, which will further promote the meat products to deteriorate or reduce the taste.

[0037] The present invention arranges an inner liner 3 and a partition 4 inside the box body 1 to form a plurality of compartments 5, so that meat products can be stored separately in the compartments 5. Therefore, during transportation, the negative impact of bumps and shakes on the meat products can be reduced, and excessive squeezing and collisions between the meat products can be prevented, thereby ensuring the appearance and taste of the meat products. In addition, the plurality of compartments 5 are convenient for separately storing meat products according to different categories, different production times, different delivery locations, etc., thereby improving the practicality of the packaging box.

[0038] After placing the meat product inside the compartment 5, close the lid body 2, open the sealing cover of the suction port 9, and then connect the suction port 9 to the negative pressure device through a pipeline to evacuate the inside of the box body 1, and then close the sealing cover of the suction port 9, thereby reducing the oxidation of the meat product and the growth of microorganisms, improving the preservation effect, and ensuring the flavor and texture of the meat product.

[0039] During transportation or storage, if the external environment changes and causes the temperature inside the box 1 to rise, the water-absorbing parts inside the inner liner 3 and the partition 4 can continuously absorb the moisture formed by the melt on the surface of the meat product through the adsorption holes 8, reduce the moisture content inside the compartment 5, prevent the formation of water accumulation and the problem of accelerated deterioration of the meat products after soaking in water, further improve the taste of the meat products, and use the water-absorbing layer 7 to reduce the loss of cold air inside the box 1 to the outside, thereby improving the insulation effect of the packaging box.

[0040] As a preferred embodiment of the present invention, an elastic frame 10 is fixedly connected to the inner side of the cover 2, and the shape of the elastic frame 10 is adapted to the compartments 5; a group of connecting holes 11 are evenly distributed inside the elastic frame 10, and the connecting holes 11 are used to connect multiple compartments 5 to each other when vacuuming, so that each compartment 5 is in a low-pressure state. After the cover 2 is closed, the elastic frame 10 just fits against the top of the liner 3 and the partition 4 and squeezes each other, thereby sealing the top of the compartment 5, improving the sealing of the entire packaging box, and isolating different compartments 5 from each other, so that different meat products will not taste each other, and if the meat product in one of the compartments 5 deteriorates, it will not affect other compartments 5.

[0041] A guide ring 12 is fixedly connected inside the connection hole 11; the diameter of the end of the connection hole 11 near the suction port 9 is enlarged and a pressure ball 13 is arranged inside the connection hole 11; a spring 14 is fixedly connected between the pressure ball 13 and the guide ring 12; in order to prevent the connection hole 11 from deforming when the elastic frame 10 is squeezed, a support tube is preferably arranged inside the connection hole 11, and the guide ring 12, the pressure ball 13 and the spring 14 are all located inside the support tube. When vacuuming, the pressure ball 13 moves toward the suction port 9 under the action of air pressure and stretches the spring 14, thereby generating a gap between the pressure ball 13 and the connection hole 11, so that air can flow smoothly through the gap and ensure that each compartment 5 forms a low-pressure state. After stopping the vacuuming, the spring 14 pulls the pressure ball 13 to reset and block the connection hole 11. At this time, the different compartments 5 are completely separated, preventing odors, microorganisms, etc. from being exchanged through the connection hole 11, and further reducing the mutual influence between different compartments 5.

[0042] As a preferred embodiment of the present invention, there is a gap between the lower side of the inner liner 3 and the bottom of the box body 1, and a water storage chamber 15 is formed; a set of drain pipes 16 are fixedly connected to the lower side of the inner liner 3, and the drain pipes 16 are connected to the cavity 6; a drain port 17 is provided at the bottom of the box body 1, and a sealing cover is provided at the outer end of the drain port 17. After the water absorption layer 7 reaches a certain amount of water absorption, the water inside it penetrates downward under the action of gravity and flows downward to the water storage chamber 15 through the drain pipe 16, thereby ensuring that the water absorption layer 7 always has a certain water absorption performance, preventing the problem that the water absorption layer 7 is difficult to continue to absorb water after reaching a full state, and the water is separated from the compartment 5 after gathering in the water storage chamber 15, and does not directly contact the meat product, further ensuring the preservation quality of the meat product, when the transportation or storage is completed, the sealing cover of the drain port 17 can be opened, the box body 1 can be tilted, and the water in the water storage chamber 15 can be poured out.

[0043] A group of water guides 18 are fixedly connected inside the water storage chamber 15; a counterweight piston 19 is slidingly and sealingly connected inside the water guide 18; a spring 20 is fixedly connected between the counterweight piston 19 and the bottom of the water guide 18; the lower end of the drain pipe 16 is connected to the top of the water guide 18; a water outlet 21 is provided at the top of the water guide 18; and a one-way valve is provided inside the drain pipe 16 and the water outlet 21. During transportation, the vehicle's bumps cause the counterweight piston 19 to move up and down inside the water guide 18. When the counterweight piston 19 moves downward, the moisture inside the water absorption layer 7 is sucked into the top of the water guide 18 through the drain pipe 16. When the counterweight piston 19 moves upward, the moisture on the top of the water guide 18 is introduced into the water storage chamber 15 through the water outlet 21. This structure can continuously suck the moisture inside the water absorbent into the water storage chamber 15, thereby improving the separation efficiency between the water absorbent and the moisture, further ensuring its water absorption effect on meat products, and using the vehicle's bumps as a power source to improve the energy-saving effect of the packaging box.

[0044] As a preferred embodiment of the present invention, a water absorbing block 22 is fixedly connected inside the adsorption hole 8, and the water absorbing block 22 and the water absorbing layer 7 are in contact with each other. The material of the water absorbing block 22 can be the same as that of the water absorbing layer 7; the side of the water absorbing block 22 away from the water absorbing layer 7 protrudes from the inner wall surface of the compartment 5. By providing the water absorbing block 22, it is in direct contact with the meat product in the compartment 5, thereby absorbing moisture on the surface of the meat product and transferring the moisture to the inside of the water absorbing layer 7, further improving the water absorption efficiency.

[0045] As a preferred embodiment of the present invention, a group of interconnected cleaning pipes 23 are fixedly connected inside the inner tank 3 and the partition 4, and the cleaning pipes 23 are arranged inside the water absorption layer 7; the cleaning pipes 23 are connected to the water injection pipes 24; the water injection pipes 24 extend to the outside of the box body 1 and are provided with a sealing cover; a group of guide holes 25 are evenly distributed on the surface of the cleaning pipe 23.

[0046] Since the water formed by the melting of the surface of the meat products usually contains blood, and the water-absorbing layer 7 is located inside the inner liner 3 and the partition 4 and is difficult to contact with the outside world, the water-absorbing layer 7 of the packaging box needs to be cleaned after being used for a period of time, otherwise a large number of microorganisms are likely to breed inside it and cause pollution to the meat products. During cleaning, the sealing cover of the water injection pipe 24 is opened, and the water injection pipe 24 is connected to the water source through a pipeline. The water flows into the inside of the cleaning pipe 23 through the water injection pipe 24, and is sprayed into the water-absorbing layer 7 along the guide hole 25 on the surface of the cleaning pipe 23, thereby flushing the blood inside the water-absorbing layer 7. Then the water flows out through the adsorption hole 8 and flushes the water-absorbing block 22. After that, the water flows into the compartment 5 to clean the compartment 5 together, and removes the blood, impurities and other dirt inside the compartment 5. The structure uses the cleaning pipe 23 to clean the water-absorbing layer 7, the water-absorbing block 22 and the compartment 5 at the same time, forming a unidirectional water flow path, thereby fully taking away the dirt, thereby improving the cleaning efficiency of the packaging box.

[0047] The cleaning pipe 23 is arranged in an "S" shape inside the water absorbing layer 7. By designing the cleaning pipe 23 in an "S" shape, the contact area between the cleaning pipe 23 and the water absorbing layer 7 can be increased, thereby extending the flushing path of the water absorbing layer 7 and improving the cleaning uniformity of the water absorbing layer 7.

[0048] The adsorption holes 8 and the guide holes 25 are misaligned with each other. Since the adsorption holes 8 and the guide holes 25 are misaligned, when the water flows into the water absorption layer 7 through the guide holes 25, the water flow will not be immediately discharged through the adsorption holes 8, but will first hit the side wall of the cavity 6, thereby dispersing the water flow, so that the water flow fully flows inside the water absorption layer 7 and takes away the blood water, and then is discharged through the adsorption holes 8.

[0049] As a preferred embodiment of the present invention, a group of drainage sheets 26 are evenly distributed inside the water absorbent block 22 on one side away from the water absorbent layer 7, and the drainage sheets 26 are preferably designed to be curved. By providing the drainage sheets 26, when the water flows outward through the inside of the water absorbent block 22, the drainage sheets 26 are used to guide a part of the water flow, so that the water flows along the surface of the drainage sheets 26 to the outside of the water absorbent block 22, and directly washes the inner wall of the compartment 5, taking away the dirt adhered to its surface, and further enhancing the cleaning effect on the inner wall of the compartment 5. The flow path of the water flow inside the water absorbent block 22 is as follows: Figure 7 shown.

[0050] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
