Description

Technical Field

[0001] This application relates to the field of pharmaceutical packaging technology, and more particularly to a pharmaceutical packaging device. Background Technology

[0002] After pharmaceutical preparation, drugs need to be packaged to facilitate storage and transportation. For some drugs, they need to be mixed with other drugs before use; therefore, mixed packaging is used to package multiple drugs together. However, this packaging method is not suitable for many drugs. Due to differences in chemical properties and physical states between different drugs, long-term mixing may lead to interactions. Furthermore, some drugs are unstable in solution and have a short shelf life; direct storage in solution can lead to reduced activity or even drug inactivation, and may even produce harmful substances, seriously affecting the quality and safety of the drug.

[0003] To address this issue, current methods involve separating and individually packaging different medications, or splitting a single medication into powder and solution packages. While these methods effectively prevent interactions between different medications and improve storage stability, they also introduce significant inconvenience during use. For instance, users need to take out different packages of medication separately and mix them according to a specific ratio, a process that is cumbersome and prone to errors.

[0016] In the housing and the main body, one is provided with a positioning part, and the other is provided with a mating part; the positioning part includes a first positioning structure and a second positioning structure, wherein the first positioning structure is closer to the first chamber than the second positioning structure; wherein, the first positioning structure is used to cooperate with the mating part to position the main body so that the movable part is in the closed position; the second positioning structure is used to cooperate with the mating part to position the main body so that the movable part is in the open position; when the movable part is in the open position, the flow cavity is located inside the partition.

[0017] In one possible implementation, both the first positioning structure and the second positioning structure are slot structures.

[0018] A guide groove is provided between the first positioning structure and the second positioning structure. One end of the guide groove is connected to the first positioning structure, and the other end is connected to the second positioning structure. The guide groove is either spiral or straight.

[0019] The mating part includes a sliding post; wherein, when the movable part is in the closed position, the sliding post is engaged in the first positioning structure; when the movable part is in the open position, the sliding post is engaged in the second positioning structure.

[0029] Of the first material and the second material, one comprises a solid pharmaceutical agent and the other comprises a solution.

[0030] The beneficial effects of this application include:

[0031] This application discloses a pharmaceutical packaging device including a bottle body, a connector, and a movable part. The connector is connected to the bottle body, and the movable part is movably connected to the connector. The connector includes a partition, which, together with the bottle body, forms a first chamber. A second chamber is disposed inside the movable part. The first chamber stores a first material, and the second chamber stores a second material. A flow-through structure is provided on the partition.

[0032] The moving part has a closed position and an open position relative to the connecting part, wherein the moving part is initially in the closed position.

[0033] When the movable part is in the closed position, the flow structure is sealed off by the movable part, and the first chamber and the second chamber are isolated. The initial closed position of the movable part enables independent storage of the first and second materials, preventing them from coming into contact and avoiding instability problems caused by prolonged mixed storage.

[0034] In the first material and the second material, at least one is a pharmaceutical agent. For example, the first material is a first pharmaceutical agent and the second material is a second pharmaceutical agent; or, for example, in the first material and the second material, one is a solid pharmaceutical agent (e.g., a powdered pharmaceutical agent) and the other is a solution, wherein the solution includes liquid water, etc.

[0035] When mixing is required, the movable part is moved to the open position, opening the flow structure and connecting the first and second chambers. The first and second materials are pre-stored in the first and second chambers, respectively, and their quantities are predetermined. When the movable part moves to the open position, shaking the bottle allows the first and second materials to be mixed in a pre-set ratio, thus meeting the requirements for medication.

[0036] Furthermore, when the movable part is in the open position, a flow cavity is formed between the first chamber and the second chamber, which are interconnected through the flow structure and the flow cavity. The presence of the flow cavity increases the space for mixing the first and second materials, allowing them to move and mix within the first chamber, the second chamber, and the flow cavity, ensuring thorough and efficient mixing within sufficient aperture. Because the flow cavity is additionally created when the movable part is in the open position, there is no need to increase the volume of the first chamber and / or the second chamber during manufacturing to facilitate mixing; the volumes of the first and second chambers only need to be controlled within a reasonable range. This effectively reduces manufacturing costs and the overall size of the pharmaceutical packaging device. Attached Figure Description

[0050] Example

[0051] See Figures 1-6In this embodiment, a pharmaceutical packaging device is proposed, including a bottle body 100, a connector 200 and a movable part 300. The connector 200 is connected to the bottle body 100, and the movable part 300 is movably connected to the connector 200.

[0052] The connector 200 includes a partition 210, which, together with the bottle body 100, forms a first chamber 110. The movable member 300 has a second chamber 310 inside. The first chamber 110 and the second chamber 310 are positioned on opposite sides of the partition 210. The first chamber 110 and the second chamber 310 are distributed along a predetermined direction, as shown in the reference diagram. Figure 2 The preset direction is parallel to the direction indicated by arrow a. In this embodiment, the preset direction is parallel to the height direction of the bottle body 100.

[0053] The first chamber 110 is used to store a first material, and the second chamber 310 is used to store a second material. At least one of the first material and the second material is a pharmaceutical agent.

[0054] In one embodiment, the first material is a first agent, and the second material is a second agent. Both the first agent and the second agent are liquid agents; or, in the first agent and the second agent, one is a liquid agent and the other is a solid agent.

[0055] In another embodiment, in the first material and the second material, one is a solid agent and the other is a solution.

[0056] Solid pharmaceuticals include powdered pharmaceuticals, and solutions include aqueous solutions. Storing solid pharmaceuticals separately from liquid pharmaceuticals or solutions can protect the active pharmaceutical substances in the solid pharmaceuticals, keeping them dry and enabling long-term storage, thereby ensuring the activity and efficacy of the active pharmaceutical substances.

[0057] A flow structure 2121 is provided on the partition 210. For example... Figure 5 As shown, the partition 210 includes a plurality of grilles 2122 arranged in a ring array, and the flow structure 2121 includes a plurality of through holes, wherein there are through holes between adjacent grilles 2122.

[0058] In this embodiment, the movable member 300 has a closed position and an open position relative to the connecting member 200. The movable member 300 can move from the closed position to the open position or from the open position to the closed position by moving relative to the connecting member 200.

[0059] The movable component 300 is initially in the closed position. When the movable component 300 is in the closed position, the flow structure 2121 is closed by the movable component 300, wherein the first chamber 110 and the second chamber 310 are isolated. When the movable component 300 is in the initial position (i.e., the closed position), the first material is stored independently in the first chamber 110, and the second material is stored independently in the second chamber 310, so that the first material and the second material do not come into contact, avoiding instability and other problems caused by long-term mixed storage. Since the first material and the second material are stored in the same pharmaceutical packaging device, it facilitates transportation, carrying, and use.

[0060] When the movable part 300 is in the open position, the flow structure 2121 is opened, and a flow cavity 213 is formed between the first chamber 110 and the second chamber 310. The first chamber 110 and the second chamber 310 are interconnected through the flow structure 2121 and the flow cavity 213. The first material and the second material are pre-stored in the first chamber 110 and the second chamber 310, respectively. Therefore, the amounts of the first material and the second material are fixed. When the movable part 300 moves to the open position, the first material and the second material can be mixed according to the set ratio by shaking the bottle 100, thereby meeting the requirements for medication.

[0061] Furthermore, when the movable part 300 is in the open position, a flow cavity 213 is formed between the first chamber 110 and the second chamber 310. The first chamber 110 and the second chamber 310 are interconnected through the flow structure 2121 and the flow cavity 213. The presence of the flow cavity 213 increases the space for the first material and the second material to mix, allowing the first material and the second material to move and mix within the first chamber 110, the second chamber 310, and the flow cavity 213, ensuring that the first material and the second material can be fully and efficiently mixed within a sufficient aperture.

[0062] Since the movable part 300 expands the flow cavity 213 when it is in the open position, during manufacturing, there is no need to increase the volume of the first chamber 110 or / and the second chamber 310 to facilitate the mixing of the drugs. It is sufficient to keep the volumes of the first chamber 110 and the second chamber 310 within a reasonable range. In this way, the manufacturing cost can be effectively reduced and the overall volume of the drug packaging device can be reduced.

[0063] The operation process of the pharmaceutical packaging device is roughly as follows: the movable part 300 is initially in the closed position, and the movable part 300 is driven to move to the open position; the bottle body 100 is shaken to repeatedly mix the first material and the second material; the movable part 300 is driven to move to the closed position, at which time the first chamber 110 stores the mixed medicine after the first material and the second material are mixed; the press-type nozzle 500 on the bottle body 100 is pressed to spray the mixed medicine from the press-type nozzle 500.

[0064] The bottle body 100 has a cavity. A partition 210 is located inside the cavity, and the partition 210 and the inner wall of the cavity form a first chamber 110, wherein the first chamber 110 is part of the cavity.

[0065] like Figures 2-6 As shown, the connector 200 also includes a housing 220, one end of which is connected to the partition 210. The housing 220 is at least partially located inside the cavity, and the outer wall of the housing 220 is sealed to the inner wall of the cavity. In this embodiment, the housing 220 is entirely located inside the cavity.

[0066] A first assembly structure is provided on the outer wall of the shell 220, and a second assembly structure is provided on the inner wall of the cavity. The first assembly structure is connected to the second assembly structure, thereby realizing the connection between the bottle body 100 and the connector 200.

[0067] In this embodiment, the first assembly structure includes an external thread, and the second assembly structure includes an internal thread corresponding to the external thread. Thus, the bottle body 100 and the connector 200 are connected by a threaded connection. The fit between the external and internal threads also achieves a sealing effect.

[0068] In other embodiments, in the first assembly structure and the second assembly structure, one is a snap-fit ​​and the other is a slot, so that the bottle body 100 and the connector 200 are connected by snap-fit. For sealing effect, a sealing ring or sealant can be provided between the shell 220 and the cavity. In addition, the bottle body 100 and the connector 200 can also be connected by bonding, laser welding, or other methods.

[0069] It should be noted that when the driving movable part 300 moves to the closed or open position, the bottle body 100 and the connecting part 200 are always in a relatively fixed state.

[0070] like Figures 2-6As shown, the partition 210 includes an end cap 211 and a cover 212, with a flow structure 2121 disposed on the cover 212. The top end of the cover 212 is connected to the end cap 211, and the bottom end is connected to the housing 220. There is a gap between the cover 212 and the inner wall of the cavity, wherein the gap between the cover 212 and the inner wall of the cavity gradually decreases from the top end to the bottom end of the cover 212.

[0071] like Figure 4 and Figure 6 As shown, the movable component 300 includes a closing portion 320, which surrounds the second chamber 310. The closing portion 320 is used to close the flow structure 2121, wherein the outer surface of the closing portion 320 is conical. The inner wall of the cover 212 is adapted to the outer surface of the closing portion 320 and is also conical.

[0072] When the movable part 300 is in the closed position, the outer surface of the closing part 320 is sealed and fitted against the inner wall of the cover 212. Since the outer surface of the closing part 320 and the inner wall of the cover 212 are conical, they can fit tightly together and achieve a seal.

[0073] When the movable part 300 is in the open position, there is a gap between the closed part 320 and the cover 212 along a preset direction. The first chamber 110, the flow chamber 213, and the second chamber 310 are sequentially distributed along the preset direction, thus increasing the space for mixing the first and second materials. This allows the first and second materials to move and mix within the first chamber 110, the flow chamber 213, and the second chamber 310, ensuring that the first and second materials can be fully and efficiently mixed within sufficient aperture. Because the first chamber 110, the flow chamber 213, and the second chamber 310 are sequentially distributed and connected along the preset direction, when mixing the reagent, refer to... Figure 2 Simply hold the bottle 100 and shake it along the height of the bottle 100. It is easy to hold and easier to operate.

[0074] In this embodiment, the movable component 300 further includes a main body 330, and a housing 220 is fitted onto the main body 330. The main body 330 and the housing 220 are movably and sealingly connected. When the main body 330 and the housing 220 are rotatably connected, a seal can be achieved between them via a threaded connection; when the main body 330 and the housing 220 are slidably connected, a seal can be achieved between them via a sealing ring or other sealing element.

[0075] In the housing 220 and the main body 330, one is provided with a positioning part and the other is provided with a mating part 420.

[0076] In this embodiment, the positioning part is disposed on the housing 220, and the mating part 420 is disposed on the main body 330. In other embodiments, the positioning part may be disposed on the main body 330, and the mating part 420 may be disposed on the housing 220, as needed.

[0077] like Figure 3 and Figure 5 As shown, the positioning part includes a first positioning structure 411 and a second positioning structure 412.

[0078] The first positioning structure 411 is closer to the first chamber 110 than the second positioning structure 412. The first positioning structure 411 is used to cooperate with the mating part 420 to position the main body 330 so that the movable part 300 is in the closed position; the second positioning structure 412 is used to cooperate with the mating part 420 to position the main body 330 so that the movable part 300 is in the open position.

[0079] The positioning of the main body 330 is achieved through the first positioning structure 411 and the second positioning structure 412. When the user moves the main body 330, the cooperation between the mating part 420 and the first positioning structure 411 or the second positioning structure 412 enables the main body 330 to move accurately to the closed position or the open position, thereby ensuring that the flow structure 2121 is completely closed or completely opened.

[0080] Reference Figure 6 When the movable part 300 is in the open position, the flow cavity 213 is located inside the partition 210, thereby making full use of the internal space of the partition 210.

[0081] In this embodiment, both the first positioning structure 411 and the second positioning structure 412 are slot structures. A guide groove 413 is provided between the first positioning structure 411 and the second positioning structure 412. One end of the guide groove 413 is connected to the first positioning structure 411, and the other end is connected to the second positioning structure 412. The guide groove 413 is spiral or straight.

[0082] In this embodiment, the main body 330 is rotatably connected to the housing 220, and the guide groove 413 is spiral-shaped. In other embodiments, the main body 330 is slidably connected to the housing 220, and the guide groove 413 is straight. The relative sliding direction between the main body 330 and the housing 220 is parallel to a preset direction, and the guide groove 413 is also parallel to the preset direction.

[0083] The mating part 420 includes a sliding post. When the movable part 300 is in the closed position, the sliding post is engaged in the first positioning structure 411; when the movable part 300 is in the open position, the sliding post is engaged in the second positioning structure 412.

[0084] The sliding post and the guide groove 413 are slidably connected. The guide groove 413 is used to guide the sliding post to move it from the closed position to the open position, or from the open position to the closed position.

[0085] like Figures 2-6 As shown, the main body 330 has an exposed portion 340 at the end away from the closed portion 320, which is located outside the bottle body 100 and the shell 220. The inner diameter of the bottle body 100 and the inner diameter of the shell 220 are both smaller than the outer diameter of the exposed portion 340. The outer surface of the exposed portion 340 is provided with an anti-slip structure to increase friction, which can be a texture, groove, or coating. When it is necessary to move the movable part 300, the user can hold the bottle body 100 with one hand and the exposed portion 340 with the other. Then, by rotating the movable part 300, the movable part 300 can be moved to the open or closed position. The anti-slip structure can play an anti-slip role and prevent slippage during operation.

[0086] The main body 330 has a hollow cavity 331 inside, and ribs 332 are arranged inside the hollow cavity 331. The hollow cavity 331 can reduce the weight of the main body 330, and the ribs 332 can improve the structural strength.

[0087] like Figure 1 , Figure 2 and Figure 7 As shown, a press-type nozzle 500 is provided on the bottle body 100, and the suction tube 507 of the press-type nozzle 500 is located in the first chamber 110.

[0088] A recessed portion 2111 is provided on the side of the connector 200 opposite to the second chamber 310, wherein a portion of the straw 507 is located in the recessed portion 2111, and there is a gap between the straw 507 and the connector 200. This structural arrangement allows the straw 507 to be as close as possible to the bottom of the first chamber 110, thereby enabling the suction of the mixed medicine located at the bottom of the first chamber 110 and avoiding waste of the mixed medicine at the bottom of the first chamber 110.

[0089] like Figure 7 and Figure 8 As shown, the press-type nozzle 500 includes a mounting cover 501, a bracket 502, a pressing element 503, a mounting tube 504, a piston 505, a storage cylinder 506, a suction tube 507, and a nozzle 508.

[0090] The mounting cap 501 is installed on the bottle mouth of the bottle body 100, the bracket 502 is fixedly installed inside the mounting cap 501, and the pressing member 503 is fixedly connected to the mounting tube 504.

[0091] The mounting tube 504 is movably inserted into the bracket 502. A core rod 509 is provided inside the mounting tube 504, and a liquid channel 510 for liquid flow is provided between the core rod 509 and the mounting tube 504. The core rod 509 includes a flange 511 located outside the mounting tube 504, and a passage gap 512 is provided between the flange 511 and the mounting tube 504, the passage gap 512 communicating with the liquid channel 510.

[0092] A first spring 513 is fitted onto the mounting tube 504. One end of the first spring 513 abuts against the mounting tube 504, and the other end abuts against the piston 505.

[0093] Piston 505 is sleeved on mounting tube 504 and located inside storage cylinder 506. The inner lip 514 of piston 505 is slidably and sealingly fitted with the outer wall of mounting tube 504, and the outer lip 515 of piston 505 is slidably and sealingly fitted with the inner wall of storage cylinder 506. The bottom of the inner lip 514 of piston 505 is used to close the passage gap 512.

[0094] Storage cylinder 506 is fixedly connected to support 502. Storage cylinder 506 includes a variable volume cavity 516, and piston 505 is located at the top of cavity 516.

[0095] A movable ball 517 and a second spring 518 are disposed within the cavity 516. The movable ball 517 is located at the bottom of the cavity 516 and is used to connect or disconnect the storage cylinder 506 from the straw 507. One end of the second spring 518 abuts against the inner wall of the storage cylinder, and the other end abuts against the protruding edge 511. The second spring 518 and the first spring 513 are respectively positioned on both sides of the protruding edge 511.

[0096] The straw 507 is connected to the storage cylinder and is located in the first chamber 110.

[0097] The nozzle 508 is connected to the mounting cover 501, wherein the end of the mounting tube 504 away from the suction tube 507 is connected to the nozzle 508.

[0098] exist Figure 7 In the middle, the pressing element 503 is in the initial position.

[0099] After the first and second materials are mixed, the pressing element 503 is pressed down, causing the mounting tube 504, core rod 509, and piston 505 to move downwards, and the volume of the cavity 516 to decrease. Correspondingly, the first spring 513 and the second spring 518 are compressed, increasing the pressure inside the cavity 516. This causes the movable ball 517 to seal the passage between the storage cylinder 506 and the suction tube 507. Simultaneously, under the action of air pressure, the air inside the cavity 516 pushes the piston 505 upwards, opening the passage gap 512. Thus, the air inside the cavity 516 is discharged to the outside of the device through the passage gap 512, the liquid channel 510, and the nozzle 508. When the air pressure inside the cavity 516 decreases to a certain value, the piston 505 moves downwards under the action of the first spring 513, causing the passage gap 512 to be closed again. When the pressure on the pressing part 503 is released, under the action of the second spring 518, the mounting tube 504, the core rod 509 and the piston 505 all move upward and return to their initial positions, and the volume of the cavity 516 increases and returns to its initial volume. Since the air in the cavity 516 is discharged, a negative pressure environment is formed inside the cavity 516.

[0100] By repeatedly pressing and releasing the pressing element 503, the air in the cavity 516 can be emptied as much as possible, thereby creating a vacuum environment inside the cavity 516.

[0101] When a vacuum environment is created inside the cavity 516, the mixed reagent in the first chamber 110 is drawn into the suction tube 507 under the negative pressure, and pushes open the movable ball 517 to enter the cavity 516. Subsequently, by pressing the pressing member 503, the mixed reagent in the cavity 516 is discharged from the outside of the device through the passage gap 512, the liquid channel 510 and the nozzle 508, thus making it available to the user.

[0102] The above description only illustrates the structure of the press-type nozzle 500 in this embodiment. In other embodiments, other press-type nozzles 500 with existing structures may also be used.

[0103] like Figure 1 and Figure 7 As shown, the outer cover of the pressing member 503 is provided with a protective cover 519; when the pressing member 503 is not needed, the protective cover 519 is placed on the pressing member 503 to prevent the pressing member 503 from being accidentally touched. The end of the nozzle 508 is provided with a protective sleeve 520; when the agent is not needed, the protective sleeve 520 is installed on the nozzle 508 to prevent dust and other contaminants from entering the nozzle 508.

[0104] The pharmaceutical packaging device proposed in this embodiment enables the independent storage of the first material and the second material. When medication is needed, the movable part 300 is moved to the open position, and the bottle 100 is shaken to mix the first material and the second material according to a set ratio, making the operation simple and convenient.
