Description

Technical Field

[0001] The invention relates to the technical field of storage and transportation of generic drugs, and in particular to a generic drug transport and storage box. Background Art

[0002] Generic drugs are imitations of brand-name drugs that are identical in dosage, safety and efficacy, quality, effects, and indications. More than 150 patented drugs with a total value of more than $34 billion will expire in the world. After the expiration, other countries and pharmaceutical companies can produce generic drugs.

[0003] As a medicine, generic drugs generally need to be refrigerated during storage and transportation. During storage, generic drugs are often placed in special cold storage or freezers, and during transportation, storage boxes with refrigeration functions are often used to transport generic drugs.

[0004] The Chinese patent application number CN202323337679.7 discloses a smart packaging box for cold chain transportation of medicines, including a box body, a storage chamber formed on the box body, wherein the four corners of the top wall of the box body are formed with movable grooves, the bottoms of the four movable grooves are fixedly welded with telescopic rods, the tops of the four telescopic rods are connected with a top cover plate, the four corners of the top wall of the top cover plate are formed with adding ports, the four adding ports are fixedly bonded with storage boxes extending toward the bottom of the top cover plate, the four sides of the top wall of the box body are provided with slots, the four storage boxes are respectively inserted into the four slots, and multiple groups of cold air outlets are provided on the side of the four storage boxes facing the movable grooves, so as to facilitate the release of cold air, and a number of air holes are provided on the inner walls of the four sides of the storage chamber. The smart packaging box for cold chain transportation of medicines will not touch the medicines when replacing ice bags or adding dry ice, and will not damage the medicines, which is conducive to protecting the medicines. Since the cooling materials are arranged in the four side walls of the storage room, the cold energy is transferred inward from the four sides of the storage room, resulting in lower temperature in the area close to the four sides of the storage room, while the temperature in the middle area of ​​the storage room is higher. The temperature in the storage room is uneven, so the medicines in the storage room are cooled unevenly and the refrigeration effect is poor.

[0005] A Chinese patent with application number CN202310375729.6 discloses a drug refrigerated transport box for marine animals. It includes a box body, in which a refrigerated chamber, a cooling material chamber, a tool compartment, and a spring chamber are arranged. The cooling material chamber and the spring chamber are connected through a connecting hole. A connecting block is provided at the first end of the refrigerated chamber, and a first spring is abutted between the connecting block and the inner wall of the spring chamber. Multiple refrigerated chambers are independently arranged to prevent medicine bottles from colliding with each other. This transport box is provided with multiple independent refrigerated chambers, each of which contains a medicine bottle, and the medicine bottles are placed to prevent collision with each other. However, only medicine bottles of fixed sizes can be placed in the refrigerated chamber of this transport box. In actual use, medicine bottles have various sizes and specifications. Smaller-sized medicine bottles placed in the refrigerated chamber will sway and collide with the side walls of the refrigerated chamber, while larger-sized medicine bottles cannot be placed in the refrigerated chamber. Therefore, the scope of application of this transport box is relatively narrow.

[0006] Based on the above analysis, the staff found that the existing transport boxes have the following problems to be solved:

[0007] 1. To achieve the refrigeration function, existing transport boxes need to add cooling materials. Generally, the cooling materials are placed on the side / top / bottom of the box. The temperature inside the box is uneven, and the temperature of each part of the box cannot be accurately controlled. This makes the temperature in the box too low or too high. In severe cases, the medicines will be scrapped, resulting in poor refrigeration effect.

[0008] 2. Existing transport boxes that can hold medicine bottles generally have holes / cavities of fixed sizes, which can only hold medicine bottles of a specific size, have a narrow scope of application, and cannot meet the needs of holding medicine bottles of various sizes. Summary of the invention

[0009] The purpose of the present invention is to provide a generic drug transport and storage box, which has the characteristics of uniform and controllable internal temperature and can fix medicine bottles of various sizes.

[0010] The above technical objectives of the present invention are achieved through the following technical solutions:

[0011] A generic drug transport and storage box, comprising a box body and a cover body, including:

[0012] The upper telescopic tube and the lower telescopic tube both include a fixed tube, a movable tube, a spring, and a self-closing structure. The movable tube is slidably connected in the fixed tube, and one end of the movable tube extends to the outside of the fixed tube. The spring is arranged in the fixed tube and connected to the other end of the movable tube. The self-closing structure is arranged at the end of the movable tube. When the movable tube of the upper telescopic tube abuts against the movable tube of the lower telescopic tube, the self-closing structure opens to make the upper telescopic tube and the lower telescopic tube connected. Otherwise, the self-closing structure is in a closed state.

[0013] An upper connecting plate is fixedly arranged in the cover body, the upper connecting plate is connected with a plurality of upper telescopic tubes, the fixed tubes of the upper telescopic tubes are fixedly connected to the upper connecting plate, and the movable tubes of the upper telescopic tubes are arranged vertically downward;

[0014] A lower connecting plate is fixedly arranged in the box body, the lower connecting plate is connected with a plurality of lower telescopic tubes, the fixed tubes of the lower telescopic tubes are fixedly connected to the lower connecting plate, and the movable tubes of the lower telescopic tubes are arranged vertically upward;

[0015] A storage cavity for storing medicine is formed between the upper connecting plate and the lower connecting plate;

[0016] The movable tube of the upper telescopic tube is arranged opposite to the telescopic tube of the lower telescopic tube, and the ends of the two are butted against each other when the cover body is closed on the box body;

[0017] The cold storage chamber is arranged at the bottom of the box body and is used for storing dry ice.

[0018] Preferably, the self-closing structure includes a sealing plate hinged at the end of the movable tube, and a torsion spring is arranged at the hinge between the sealing plate and the movable tube so that the sealing plate has a tendency to rotate toward the outside of the movable tube. A baffle is fixedly arranged on the inner wall of the end of the movable tube, and the baffle is arranged relative to the hinge between the sealing plate and the movable tube. One end of the baffle extends to the outside of the movable tube. The upper and lower self-closing structures are arranged in a centrally symmetrical manner. When the ends of the two movable tubes are abutted, the baffle on one of the movable tubes is inserted into the other movable tube and abuts against the sealing plate in the other movable tube, so that the two movable tubes are connected.

[0019] Preferably, the cross-sectional shape of the baffle is an arc shape matching the inner wall of the movable tube.

[0020] Preferably, a liftable lifting plate is provided above the upper connecting plate, a guide pipe is connected to the top of the movable tube of the upper telescopic tube, the guide pipe extends vertically upward through the lifting plate and is connected to the space above the lifting plate, and the guide pipe is fixedly connected to the lifting plate.

[0021] Preferably, sealing strips are arranged around the lifting plate.

[0022] Preferably, a guide hole is provided on the upper surface of the box body, and a guide rod corresponding to the guide hole is provided at the bottom of the cover body.

[0023] Preferably, a pressure control valve is provided on the top of the cover body, and when the pressure in the box body exceeds a preset value, the pressure control valve opens.

[0024] Preferably, a pressure relief port is provided on the top of the cover body, and the pressure relief port is connected to the sealing plug.

[0025] Preferably, a water absorbing layer is provided on the side of each movable tube.

[0026] Preferably, a magnet is disposed at the end of each movable tube.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. When storing and transporting medicines, multiple upper telescopic tubes and multiple lower telescopic tubes are connected, and dry ice is used as a cooling medium. After the dry ice sublimates, the gas enters the upper part of the cover body from the cold storage cavity through the lower telescopic tube and the upper telescopic tube, and the cold energy is transferred to the upper telescopic tube and the lower telescopic tube, and then the cold energy is transferred from the upper telescopic tube and the lower telescopic tube to the air in the storage cavity. Since multiple upper telescopic tubes and lower telescopic tubes are provided, the cold energy can be transferred to various positions of the storage cavity, so that the cold energy is evenly distributed in the storage cavity, and the temperature in the storage cavity is more uniform, which solves the problem of local temperature being too high / too low;

[0029] 2. When storing medicine bottles, the storage box can fix medicine bottles of different sizes in the storage cavity to prevent the medicine bottles from shaking during transportation and from collision and damage between medicine bottles. Moreover, the medicine bottles can be placed at will in the storage cavity. When the cover is closed on the box body, a part of the upper telescopic tube and the lower telescopic tube will press against the medicine bottle, and a part of the upper telescopic tube and the lower telescopic tube will be connected to surround the medicine bottle, thereby fixing the medicine bottle. Therefore, when placing the medicine bottle, there is no need to place it carefully, and it is convenient to use;

[0030] 3. By setting a water-absorbing layer on the side of the movable tube, the moisture in the storage chamber can be absorbed. Because the temperature drop in the storage chamber will cause the water molecules in the air to condense into water droplets on the surface of the object, more moisture can be absorbed by setting up multiple movable tubes to prevent the medicine from getting damp.

DETAILED DESCRIPTION

[0041] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0042] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0043] Example:

[0044] like Figure 1 As shown, the transport box in this embodiment is composed of a cover body 2 and a box body 3, which are separately arranged. After the cover body 2 is covered on the box body 3, it is locked by a lock. The lock belongs to the prior art and is not drawn in the figure. A lower connecting plate 32 is horizontally arranged in the box body 3, and a plurality of lower telescopic tubes 31 are vertically fixedly installed on the lower connecting plate 32. Four guide holes 33 are vertically opened on the upper surface of the box body 3 along the four corners of its edge. Four guide rods 25 corresponding to the guide holes 33 are fixedly connected at the bottom of the cover body 2. When the cover body 2 is covered on the box body 3, the guide rods 25 are inserted into the guide holes 33 so that the lower telescopic tubes 21 to be introduced later can be aligned with the lower telescopic tubes 31. A pressure control valve 26 and a sealing plug 28 are arranged on the top of the cover body 2.

[0045] like Figure 2 and Figure 3 As shown, a cold storage chamber 11 is provided at the bottom of the box body 3, and the cold storage chamber 11 is used to store cooling materials for generating cold. A detachable cold storage box 12 is provided in the cold storage chamber 11 for convenient storage / removal of cooling materials. Figure 2The cold storage box 12 can be taken out / put back by sliding the cold storage box 12 in the left / right direction. The cold storage box 12 is fixed in the box body 3 by a buckle. The buckle belongs to the prior art, so it will not be repeated here. An upper connecting plate 22 is horizontally connected to the cover body 2, and a storage cavity 1 for placing medicine bottles is formed between the upper connecting plate 22 and the lower connecting plate 32. A plurality of upper telescopic tubes 21 are connected to the upper connecting plate 22. A lifting plate 23 of a lifting plate 23 is also arranged above the upper telescopic tube 21. A pressure relief port 27 is provided at the top of the cover body 2, and a sealing plug 28 is connected to the pressure relief port 27.

[0046] The upper telescopic tube 21 and the lower telescopic tube 31 are both composed of a fixed tube 4, a movable tube 41, and a spring 42. The movable tube 41 is slidably connected in the fixed tube 4, and one end of the movable tube 41 extends to the outside of the fixed tube 4. The spring 42 is installed in the fixed tube 4, one end of which is against the connecting block at the end of the fixed tube 4, and the other end is connected to the end of the movable tube 41. The movable tube 41 is subjected to force to compress the spring 42 and completely slide into the fixed tube 4. The fixed tube 4 of the lower telescopic tube 31 is fixedly connected to the lower connecting plate 32, and the movable tube 41 of the lower telescopic tube 31 is vertically upward. The fixed tube 4 of the upper telescopic tube 21 is fixedly connected to the upper connecting plate 22, and the movable tube 41 of the upper telescopic tube 21 is vertically downward. The upper telescopic tube 21 corresponds to the lower telescopic tube 31 one by one. When the cover body 2 is covered on the box body 3, the movable tube 41 of the upper telescopic tube 21 is against the movable tube 41 of the lower telescopic tube 31. The side of the movable tube 41 is provided with a water absorbing layer 44, which is made of a sponge material and wrapped around the outer side of the movable tube 41. The upper telescopic tube 21 is configured so that only the movable tube 41 thereof extends below the upper connecting plate 22, and the lower telescopic tube 31 is configured so that only the movable tube 41 thereof extends above the lower connecting plate 32.

[0047] like Figure 4 As shown, a magnet 45 is installed at the end of each movable tube 41, so that the ends of the two movable tubes 41 can be firmly adsorbed together when they are against each other. The magnet 45 is annular, and the diameter of the central hole is smaller than the diameter of the movable tube 41. A self-closing structure 5 is installed at the end of each movable tube 41. The self-closing structure 5 includes a sealing sheet 51 and a baffle 52. The sealing sheet 51 is hinged inside the opening of the movable tube 41 and is located below the magnet 45. A torsion spring (not shown in the figure) is installed at the hinge of the sealing sheet 51 and the movable tube 41, and the torsion spring makes the sealing sheet 51 have a tendency to rotate to the outside of the movable tube 41. The position of the baffle 52 is opposite to the hinge of the sealing sheet 51, and one end of the baffle 52 extends to the outside of the opening of the movable tube 41. The sealing sheet 51 is close to the end surface of the baffle 52, and the end of the baffle 52 and the magnet 45 are against each other, so that the sealing sheet 51 is kept in the movable tube 41, and the opening of the movable tube 41 is kept in a sealed state.

[0048] like Figure 5As shown, the cross section of the baffle 52 is annular, and the baffle 52 is arranged along the inner wall of the magnet 45. The length of the cross section of the baffle 52 is half of the circumference of the inner wall of the magnet 45.

[0049] like Figure 6 As shown, the self-closing structures 5 on the upper and lower corresponding movable tubes 41 are centrally symmetrical.

[0050] like Figure 7 As shown, when the two corresponding movable tubes 41 above and below are against each other, the blocking piece 52 on one movable tube 41 will be inserted into the other movable tube 41 and against the sealing piece 51 in the other movable tube 41, pushing the sealing piece 51 open, and then opening the opening of the other movable tube 41. Through the interaction of the two self-closing structures 5, the openings of the two movable tubes 41 are opened, and the two movable tubes 41 are connected. When the two movable tubes 41 are against each other, the two magnets 45 attract and adsorb each other, adsorbing the ends of the two movable tubes 41 together, and at this time, a stable and unobstructed channel is formed inside the two movable tubes 41.

[0051] like Figure 8 As shown, a sealing strip 24 is arranged around the side of the lifting plate 23 to form a well-sealed space above the lifting plate 23 to prevent the gas above the lifting plate 23 from entering the bottom of the lifting plate 23 through the gap between the lifting plate 23 and the cover 2. The lifting plate 23 and the upper telescopic tube 21 are connected by a guide tube 43.

[0052] like Fig. 9 As shown, the bottom of the guide tube 43 is connected to the top of the movable tube 41, and the top of the guide tube 43 extends upward and passes through the lifting plate 23, so that the inside of the movable tube 41 and the guide tube 43 are connected to the top of the lifting plate 23. The upper side wall of the guide tube 43 is fixedly connected to the lifting plate 23.

[0053] Working principle:

[0054] Before using the transport box, the cold storage box 12 is taken out first, and the dry ice is placed in the cold storage box 12. When placing, it is necessary to pay attention to evenly distribute the dry ice in the cold storage box 12. Then the cold storage box 12 is installed back into the cold storage cavity 11.

[0055] When placing a medicine bottle containing generic medicine in the storage chamber 1, first lift the cover 2 upwards, separate the cover 2 from the box 3, and expose the lower connecting plate 32 and the movable tube 41 of the lower telescopic tube 31. The medicine bottle is randomly placed in the storage chamber 1, and the medicine bottle falls on the lower connecting plate 32. The movable tube 41 in contact with the lower surface of the medicine bottle is compressed into the fixed tube 4 of the lower telescopic tube 31 by pressure. The lowest point of the bottom surface of the medicine bottle contacts the lower connecting plate 32, and other higher bottom surface positions are pressed by the movable tube 41.

[0056] The sealing plug 28 is removed from the pressure relief port 27 to balance the air pressure above the lifting plate 23 with the outside, so as to facilitate the movement of the lifting plate 23 and the movable tube 41 of the upper telescopic tube 21. When the cover body 2 is closed, the guide rod 25 is inserted into the guide hole 33 to align the movable tubes 41 distributed up and down. When the cover body 2 is closed, the end of the movable tube 41 located just above the medicine bottle abuts against the upper surface of the medicine bottle, and the upper and lower surfaces of the medicine bottle are pressed by the movable tubes 41 above and below the medicine bottle to preliminarily fix the medicine bottle.

[0057] After the cover body 2 is closed, the sealing plug 28 is installed on the pressure relief port 27. When the movable tubes 41 directly above and below the medicine bottle press the medicine bottle, the movable tubes 41 that are not above and below the medicine bottle abut against each other and are connected together, specifically, the lower end of the upper movable tube 41 and the upper end of the lower movable tube 41 abut against each other, that is, the upper self-closing structure 5 abuts against the lower self-closing structure 5. When the upper and lower corresponding self-closing structures 5 abut against each other, the baffle 52 on one of the self-closing structures 5 is inserted into the central hole of the annular magnet 45 of the other self-closing structure 5, and abuts against the sealing sheet 51 of the other self-closing structure 5, and the sealing sheet 51 is pushed to rotate by abutting against each other, so that the opening of the movable tube 41 where the sealing sheet 51 is located is opened. Therefore, through the interaction of the two self-closing structures 5, the two sealing sheets 51 are opened, and then the interiors of the two movable tubes 41 are connected. The ends of the mutually abutting movable tubes 41 are adsorbed together by the magnet 45, so that the movable tubes 41 are firmly connected. The ends of the other movable tubes 41 that abut against the medicine bottle are still sealed. The movable tubes 41 located on the side of the medicine bottle are connected up and down to form a fence on the side of the medicine bottle. When the medicine bottle is about to move, the movable tubes 41 block the medicine bottle to prevent the medicine bottle from displacement and collision.

[0058] Since a communicating channel is formed inside the movable tube 41 connected up and down, and the upper movable tube 41 is connected to the guide tube 43, the guide tube 43 is connected to the upper part of the lifting plate 23. After the gas above the lifting plate 23 accumulates to a certain volume, the air pressure is increased, and a downward pressure is generated on the upper surface of the lifting plate 23, pushing the lifting plate 23 down. During the descent of the lifting plate 23, the guide tube 43 and the movable tube 41 connected to the guide tube 43 are pushed to move further downward, increasing the force of the movable tube 41 pressing against the medicine bottle, so that the medicine bottle is fixed more firmly. When the pressure in the space above the lifting plate 23 is greater than the preset value, the pressure control valve 26 will automatically open to discharge excess gas.

[0059] It should be noted that the connection between the cover body 2 and the box body 3 is not absolutely sealed, and the connection between the upper connecting plate 22 and the cover body 2 is not completely sealed, which makes the space between the lifting plate 23 and the upper connecting plate 22 not sealed, and the lifting plate 23 can be lifted and lowered normally.

[0060] While fixing medicine bottles of different specifications, low-temperature gas fills each movable tube 41, transferring cold energy to the movable tube 41, and the movable tube 41 then transfers the cold energy to the storage cavity 1. Since there are a large number of movable tubes 41 and they are arranged at various positions in the storage cavity 1, the cold energy can be evenly transferred to the storage cavity 1.

[0061] When the temperature in the storage chamber 1 decreases, the moisture in the air in the storage chamber 1 will liquefy and adhere to the medicine bottle. If the medicine bottle is not sealed well, the medicine will be damaged and become wasteful. The water absorption layer 44 arranged on the side of the movable tube 41 can effectively absorb the moisture in the air to reduce the water droplets attached to the medicine bottle. In addition, there are many movable tubes 41, and the sum of the surface areas of the sides thereof is large, so that the area of ​​the water absorption layer 44 that can be used for water absorption is large, and a good water absorption and moisture-proof effect can be achieved.
