Description

Technical Field

[0001] The present application relates to the technical field of storage containers, and specifically discloses a food storage container. Background Art

[0002] Food transportation can be carried out by land, air, or sea. Regardless of the above, transport and storage containers are required to load the food. Regardless of the above, the space occupied by land, air, or sea is limited, that is, the number of transport containers that can be placed in the same area is limited. Therefore, traditional storage containers have a relatively large impact on transportation efficiency. Chinese publication number CN117985321B discloses a seafood transport container with variable volume, comprising a symmetrically arranged main body, an expandable bag arranged between the main bodies, and a support assembly capable of centripetal and centrifugal movement on the main body, the support assembly being fixedly connected to the inner side of the expandable bag; the support assembly comprising a plurality of retractable skeletons and a sliding assembly capable of centripetal and centrifugal movement on the main body, the sliding assembly being fixedly connected to the skeleton; a sealing ring is provided at the connection between the main body and the expandable bag, the sealing ring being made of rubber, the main body being fixedly connected to the sealing ring, and the sealing ring being fixedly connected to the inner side of the expandable bag; a cavity is provided inside the main body, a rotating rod is rotatably connected to the outer side of the main body, a rotating disk is provided at the free end of the rotating rod passing through the cavity, a knob is provided at the end of the rotating rod away from the rotating disk, a plurality of grooves communicating with the cavity are opened inside the main body, and a mosquito coil spiral protrusion is provided on the end surface of the rotating disk close to the groove; The core design of the above solution is to act on long-shaped food, thereby solving the problem of food transportation requiring ultra-long transport containers for filling; Likewise, the above solution has some problems: 1. Although the support assembly can achieve a change in radius through centripetal and centrifugal motion, in actual use, the support assembly cannot coexist with the food, resulting in large-scale collisions, which in turn affects food quality. Secondly, the strength of the support assembly cannot be guaranteed, resulting in problems with the use of the entire device. 2. Secondly, a retractable frame is used to achieve length adjustment. Specifically, the hollow secondary rod is provided with elastic blocks that fit into connecting slots. This model is theoretically feasible, but in practice, a fatal problem exists: inserting the elastic blocks into different connecting slots through the expandable bag to adjust the length of the frame is extremely difficult, and the corresponding connecting slots cannot be found. The inventor believes that variable volume transport and storage containers for long-shaped foods still have considerable market prospects and the technical solutions of radius change and length change are still the core. Based on the above problems, the inventor proposes a food storage container. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that traditional storage containers cannot change their volume, are not suitable for the transportation of specific products, and ultimately cannot improve transportation efficiency.

[0004] In order to achieve the above object, the present invention provides the following basic scheme: A food storage container comprises an expandable bag, a first fixing member and a second fixing member respectively arranged at both ends of the expandable bag, the first fixing member being used for putting food in, the second fixing member being used for inflation, a load-bearing component being detachably connected to the ends of the interior of the expandable bag near the first fixing member and the second fixing member, a hollow skeleton for connecting the load-bearing components being detachably provided between the load-bearing components, an inflatable airbag component being connected to the second fixing member being provided on the periphery of the load-bearing component, and the inflatable airbag component changing the inner diameter of the expandable bag after inflation.

[0005] Furthermore, both ends of the expandable bag are fixed with connecting rings, and the connecting rings are fixed on the outer periphery of the end faces of the first fixing member and the second fixing member. The first fixing member and the second fixing member are both columnar structures. The first fixing member and the second fixing member are provided with several initial limiting ring grooves near the end faces of the expandable bag, and the bearing assembly is detachably connected to the initial limiting ring grooves.

[0006] Furthermore, a through threaded hole is provided on the end face of the first fixing member away from the initial limiting ring groove, and an opening cover is threadedly connected to the through threaded hole. The opening cover includes a threaded column threadedly connected to the through threaded hole, an end cover fixed to the threaded column and a knob arranged on the end cover, and a sealing gasket is provided at the connection between the end cover and the threaded column.

[0007] Furthermore, a connection limit snap-in groove is provided on the end face of the second fixing member away from the initial limit ring groove, and the connection limit snap-in groove is used to connect a portable air supply machine. A connection hole is provided on the connection limit snap-in groove, and a one-way valve is provided at the position of the connection hole. The output end of the one-way valve is connected to the initial limit ring groove.

[0008] Furthermore, a limiting block is symmetrically arranged in the initial limiting ring groove, and the end of the supporting component is in contact with the limiting block. The supporting component includes two groups of arc-shaped soft plates and a plurality of air guide holes running through the arc-shaped soft plates. The inflatable airbag component is arranged on the outer surface of the arc-shaped soft plate. The arc-shaped soft plate is artificially bent and placed in the initial limiting ring groove to contact the limiting block.

[0009] Furthermore, the hollow skeleton includes a skeleton body, a crash pad arranged on the periphery of the skeleton body, and pins fixed to both ends of the skeleton body. The pins and the skeleton body are integrally formed and connected. The pins are respectively inserted into corresponding air guide holes, and the air guide holes are connected to the inflatable airbag assembly.

[0010] Furthermore, there are at least four skeleton bodies, which are respectively arranged at the ends of the arc-shaped soft boards. The initial limiting ring grooves on the first fixing member and the second fixing member are provided with arc-shaped soft board fixing components for fixing their respective arc-shaped soft boards. The arc-shaped soft board fixing components are elastic inclined plates symmetrically arranged on the initial limiting ring grooves. The gaps between the elastic inclined plates constitute card slots, which are used to fix their respective arc-shaped soft boards.

[0011] Furthermore, the inflatable airbag assembly includes an inflatable airbag body connected to the air guide hole and a frame-type limit frame fixed on the arc-shaped soft plate. The inflatable airbag body includes a connecting part and an expansion part. The connecting part is fixed on the arc-shaped soft plate in the frame-type limit frame and connected to the air guide hole. The expansion part is arranged in the frame-type limit frame and expands along the width direction of the frame-type limit frame. The expansion direction is away from the center of the first fixing member and the second fixing member.

[0012] Furthermore, the bottoms of the first fixing member and the second fixing member are both fixedly connected with support columns.

[0013] Furthermore, the expandable bag is a highly elastic TPU storage bag.

[0014] The principles and effects of this basic solution are: 1. Compared with the existing technology, this device has a simple structure and takes the technical solutions of radius change and length change as the core. After the radius and length change, the volume of the entire device is changed, thereby expanding the volume. This ultimately solves the problem that traditional storage containers cannot change volume, are not suitable for the transportation of specific products, and ultimately cannot improve transportation efficiency.

[0015] 2. Compared with the existing technology, this device has a lower cost, eliminates the support component, and adopts an inflatable airbag component. The inflatable airbag component is used to achieve the change of the inner diameter. Compared with the support component, the inflatable airbag component has a lower cost and the product quality is more controllable.

[0016] 3. Compared with the prior art, the expandable bag in this device is integrated. The integrated expandable bag basically has no sealing problem. The inlet and outlet are set on the first fixing part, and the first fixing part is used for the input of food, thereby realizing the integration of the expandable bag, so that the expandable bag is only used for expansion, and there is no gap in the expandable bag, ensuring the stability of the expandable bag.

[0017] 4. Compared with the prior art, this device is based on the integration of expandable bags, and a hollow skeleton for connecting the load-bearing components is detachable between the load-bearing components. The hollow skeleton is still used as the core of the length change. However, the hollow skeleton in this case adopts a fixed size, and the first fixing member is used to achieve the priority input of the hollow skeleton, and then the size is directly determined. The elastic card blocks are placed in different connecting slots through the expandable bag to achieve the length adjustment of the skeleton. This method is extremely difficult, and the problem of not being able to find the corresponding connecting slot can be effectively solved. In addition, the hollow skeleton with a fixed size is better in stability, thereby further significantly improving the stability of the use of this device.

[0018] 5. Compared with the existing technology, the internal space of the expandable bag, that is, the storage space, is highly optimized. The first-generation product not only has a frame but also a supporting component. The internal space of the expandable bag in this device only has a hollow frame, which makes the internal space of the expandable bag larger and reduces the transportation damage caused by the collision between the food and the device.

[0019] 6. Compared with the prior art, the present device uses a first fixing member and a second fixing member, which first expand the expandable bag and then use the inflatable airbag assembly to achieve overall expansion of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0024] Implementation example Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown: A food storage container includes an expandable bag 9, a first fixing member 1 and a second fixing member 2 respectively arranged at both ends of the expandable bag 9, the first fixing member 1 is used for putting food into, and the second fixing member 2 is used for inflation. The interior of the expandable bag 9 is detachably connected to the ends near the first fixing member 1 and the second fixing member 2 with a load-bearing component, and a hollow skeleton 22 for connecting the load-bearing components is detachably provided between the load-bearing components. The outer periphery of the load-bearing component is provided with an inflatable airbag component 12 connected to the second fixing member 2. After the inflatable airbag component 12 is inflated, the inner diameter of the expandable bag 9 is changed.

[0025] Regarding the first fixing member 1 and the second fixing member 2: Both ends of the expandable bag 9 are fixed with connecting rings 10, which are detachably connected to the outer periphery of the end faces of the first fixing member 1 and the second fixing member 2. The first fixing member 1 and the second fixing member 2 are both columnar structures. The first fixing member 1 and the second fixing member 2 are provided with several initial limiting ring grooves 17 near the end faces of the expandable bag 9, and the bearing assembly is detachably connected to the initial limiting ring grooves 17.

[0026] Regarding the connecting ring 10: Since the expandable bag 9 needs to be connected to the first fixing member 1 and the second fixing member 2, in order to ensure the connection strength, this case adopts a hard connection, that is, a connecting ring 10 is provided. The connecting ring 10 connects the outer periphery of the end surfaces of the first fixing member 1 and the second fixing member 2 to prevent the expandable bag 9 from being directly connected to the first fixing member 1 and the second fixing member 2; About the initial limiting ring groove 17: The initial limiting ring groove 17 is used in conjunction with the bearing component, such as Figure 2 As shown, there are two groups of initial limiting ring grooves 17. When the bearing components are placed in different initial limiting ring grooves 17, the subsequent volume changes of the expandable bag 9 are different. That is, the closer the bearing components are to the center of the first fixing member 1 and the second fixing member 2, the smaller the subsequent volume change of the expandable bag 9, and vice versa.

[0027] The expandable bag 9 has a limit expansion factor. Since the bearing assembly includes two sets of arc-shaped soft plates 11, the arc-shaped soft plates 11 have different installation positions, that is, they are placed in different initial limiting ring grooves 17. Figure 2 It can be seen that the initial limiting ring groove 17 is respectively close to the center of the first fixing member 1 and the second fixing member 2 and away from the center of the first fixing member 1 and the second fixing member 2. Therefore, because the expandable bag 9 is installed based on the arc-shaped soft plate 11, when the position of the arc-shaped soft plate 11 is closer to the center of the first fixing member 1 and the second fixing member 2, and because the expandable bag 9 has a limit expansion factor, the smaller the expansion bag 9 expands outward, the smaller the volume change. Naturally, the opposite is true.

[0028] A through threaded hole 16 is provided on the end face of the first fixing member 1 away from the initial limiting ring groove 17, and an opening cover is threadedly connected to the through threaded hole 16. The opening cover includes a threaded column 6 threadedly connected to the through threaded hole 16, an end cover 8 fixed to the threaded column 6 and a knob 15 arranged on the end cover 8. A sealing gasket 7 is provided at the connection between the end cover 8 and the threaded column 6.

[0029] Specifically, the cover is opened through the threaded connection, and the through threaded hole 16 is exposed. Food is put into the expandable bag 9 through the through threaded hole 16, and the sealing gasket 7 improves the sealing property of the connection.

[0030] A connecting limit snap-in groove 4 is formed on the end face of the second fixing member 2 away from the initial limit ring groove 17. The connecting limit snap-in groove 4 is used to connect a portable air supply machine. A connecting hole is provided on the connecting limit snap-in groove 4. A one-way valve 3 is provided at the position of the connecting hole. The output end of the one-way valve 3 is connected to the initial limit ring groove 17.

[0031] About the connection limit card slot 4: Figure 1 As shown, the connection limit clamping groove 4 is mainly used in conjunction with the portable air supply machine. The portable air supply machine is fixed to the second fixing member 2 through the connection limit clamping groove 4. Then the portable air supply machine is started, and the gas enters the expandable bag 9 through the one-way valve 3. Since the output end of the one-way valve 3 is connected to the initial limit ring groove 17; The limiting blocks are symmetrically arranged in the initial limiting ring groove 17. The limiting block on the first fixing part 1 is the first limiting block 18, and the limiting block on the second fixing part 2 is the second limiting block 19. The end of the load-bearing component contacts the limiting block. The load-bearing component includes two groups of arc-shaped soft plates 11 and a plurality of air guide holes 13 running through the arc-shaped soft plates 11. The inflatable airbag component 12 is arranged on the outer surface of the arc-shaped soft plate 11. The arc-shaped soft plate 11 is artificially bent and placed in the initial limiting ring groove 17 to contact the limiting block. The air guide hole 13 is located on the outside of the arc-shaped soft plate 11 and is provided with a connection point 14, which connects the arc-shaped soft plate 11 and the hollow skeleton 22.

[0032] After the two curved soft boards 11 are installed, the length of the device needs to be determined. Therefore, a hollow frame 22 is provided. The size of the hollow frame 22 is directly determined manually according to the size of the stored food.

[0033] The hollow skeleton 22 includes a skeleton body 2201, a crash pad 2203 arranged on the periphery of the skeleton body 2201, and a pin 2202 fixed to both ends of the skeleton body 2201. The pin 2202 and the skeleton body 2201 are integrally formed and connected. The pin 2202 is inserted into the corresponding air guide hole 13 through the connection point 14, and the air guide hole 13 is connected to the inflatable airbag assembly 12.

[0034] Specifically, the portable air supply unit is started to generate gas, which enters the initial limiting ring groove 17 through the one-way valve 3. Since the curved soft plate 11 is installed on the initial limiting ring groove 17 and the curved soft plate 11 is provided with air guide holes 13, and the air guide holes 13 use the skeleton body 2201 to implement gas transmission, the inflatable airbag assembly 12 is expanded by gas. A connecting tube 20 is provided at the bottom of the initial limiting ring groove 17. The connecting tube 20 is used to align with the air guide holes 13 on the curved soft plate 11. The number of connecting tubes 20 is greater than the number of air guide holes 13. The connecting tubes 20 that are not connected to the air guide holes 13 are used to inject air into the expandable bag 9. The injection of internal air is mainly for the transportation of fresh food to avoid anaerobic respiration. For fresh fruits and vegetables and other vital foods, respiration is still required to maintain life activities during transportation. An appropriate amount of air can provide oxygen to ensure normal respiration, thereby maintaining the freshness and quality of the food. If the air supply is insufficient, anaerobic respiration of fruits and vegetables will occur, producing harmful substances such as alcohol, affecting their taste and nutritional value.

[0035] Specifically: If the connecting tube 20 exists every 30 degrees, then the position of the air guide hole 13 is designed every 60 degrees. Naturally, the connecting tube 20 and the air guide hole 13 are naturally connected at the 60-degree position, and there is no problem that the connecting tube 20 and the air guide hole 13 cannot be installed.

[0036] There are at least four skeleton bodies 2201, and the skeleton bodies 2201 are respectively arranged at the ends of the arc-shaped soft plates 11 to maximize the internal space of the expandable bag 9 and reduce the obstruction of the skeleton body 2201. The initial limiting ring grooves 17 on the first fixing member 1 and the second fixing member 2 are provided with arc-shaped soft plate fixing components for fixing their respective arc-shaped soft plates 11. The arc-shaped soft plate fixing components are elastic inclined plates 21 symmetrically arranged on the initial limiting ring grooves 17. The gaps between the elastic inclined plates 21 constitute card slots, which are used to fix their respective arc-shaped soft plates 11.

[0037] The main purpose of the elastic inclined plate 21 is to further fix the respective arc-shaped soft plates 11 to prevent the arc-shaped soft plates 11 from shaking. The inflatable airbag assembly 12 includes an inflatable airbag body connected to the air guide hole 13 and a frame-type limit frame 23 fixed on the arc-shaped soft plate 11. The inflatable airbag body includes a connecting part and an expansion part. The connecting part is fixed on the arc-shaped soft plate 11 in the frame-type limit frame 23 and connected to the air guide hole 13. The expansion part is arranged in the frame-type limit frame 23 and expands along the width direction of the frame-type limit frame 23. The expansion direction is away from the center of the first fixing member 1 and the second fixing member 2.

[0038] The purpose of providing the frame-shaped limiting frame 23 is that once the inflatable airbag body ruptures, the expandable bag 9 will not collapse quickly. The expandable bag 9 will be supported by the frame-shaped limiting frame 23 to ensure that the expandable bag 9 will not shrink quickly.

[0039] This device needs to be placed horizontally for transportation, so the bottoms of the first fixing member 1 and the second fixing member 2 are fixed with support columns 5. Since the core of this case is to change the volume by expanding the expandable bag 9, the expandable bag 9 is a highly elastic TPU storage bag.

[0040] Specific implementation process: In the first step, the food enters the expandable bag 9 through the first fixing member 1. Then, the length of the hollow frame 22 is determined according to the length of the food to be transported. The entire installation of the device is completed by installing the hollow frame 22 and the first fixing member 1 and the second fixing member 2. In the second step, the inflatable airbag assembly 12 is inflated through the second fixing member 2, thereby causing the inflatable bag 9 to expand outward, thereby achieving a change in the internal volume of the device.

[0041] The device solves the problem that traditional storage containers cannot change their volume, are not suitable for the transportation of specific products, and ultimately cannot improve transportation efficiency.

[0042] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
