Description

Technical Field

[0001] The present application relates to the technical field of pharmaceutical packaging, and in particular to a pharmaceutical packaging device. Background Art

[0002] After the preparation of drugs, they need to be packaged to facilitate storage and transportation of drugs. For some drugs, they need to be mixed with other drugs when used. For this reason, mixed packaging is used to mix multiple drugs together for packaging. However, this packaging method is not applicable to many drugs. Due to the differences in chemical properties and physical states between different drugs, they may interact with each other after being mixed together for a long time. On the other hand, some drugs are unstable in solutions and have a short shelf life. Direct storage in solution will lead to reduced activity and failure of the drugs, and may even produce harmful substances, which will seriously affect the quality and safety of the drugs.

[0003] To solve this problem, the current method is to separate different drugs and package them independently or to split a drug into dry powder and solution and package them independently. The above method can effectively avoid the interaction between different drugs and improve the storage stability of drugs, but it brings great inconvenience during use. For example, users need to take drugs of different packages separately and mix them according to a certain ratio, which is cumbersome and error-prone. Summary of the invention

[0050] Example

[0051] See also Figure 1-Figure 6In this embodiment, a medicine packaging device is proposed, including a bottle body 100, a connecting member 200 and a movable member 300, wherein the connecting member 200 is connected to the bottle body 100, and the movable member 300 is movably connected to the connecting member 200.

[0052] The connecting member 200 includes a partition 210, and the partition 210 and the bottle body 100 form a first chamber 110. The movable member 300 is provided with a second chamber 310. The first chamber 110 and the second chamber 310 are disposed on both sides of the partition 210. The first chamber 110 and the second chamber 310 are distributed along a preset direction, referring to 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 medicine.

[0054] In one embodiment, the first material is a first medicine, and the second material is a second medicine, wherein both the first medicine and the second medicine are liquid medicines; or, of the first medicine and the second medicine, one is a liquid medicine and the other is a solid medicine.

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

[0056] Solid medicines include powdered medicines, and solutions include aqueous solutions, etc. Storing solid medicines separately from liquid medicines or solutions can protect the active pharmaceutical ingredients in the solid medicines, keep the active pharmaceutical ingredients dry, and achieve long-term storage of the medicines, thereby ensuring the activity and efficacy of the active pharmaceutical ingredients.

[0057] A flow structure 2121 is provided on the partition 210. Figure 5 As shown, the partition 210 includes a plurality of grids 2122 distributed in a circular array, and the flow structure 2121 includes a plurality of through holes, wherein through holes are provided between adjacent grids 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 member 300 is initially in a closed position. When the movable member 300 is in the closed position, the flow structure 2121 is closed by the movable member 300, wherein the first chamber 110 and the second chamber 310 are in an isolated state. When the movable member 300 is in the initial position (i.e., the closed position), the first material is independently stored in the first chamber 110, and the second material is independently stored in the second chamber 310, so that the first material and the second material will not contact each other, avoiding problems such as instability caused by long-term mixed storage. Since the first material and the second material are stored in the same pharmaceutical packaging device at the same time, it is convenient for 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, wherein the first chamber 110 and the second chamber 310 are connected to each other 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. For this purpose, the amounts of the first material and the second material are determined. When the movable part 300 moves to the open position, the first material and the second material can be mixed in a set ratio by shaking the bottle body 100, thereby meeting the requirements of medication.

[0061] In addition, when the movable member 300 is in the open position, a flow cavity 213 is formed between the first chamber 110 and the second chamber 310, wherein the first chamber 110 and the second chamber 310 are connected to each other through the flow structure 2121 and the flow cavity 213. The existence of the flow cavity 213 increases the space for mixing the first material and the second material, so that the first material and the second material can move and mix in 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 will additionally expand the flow cavity 213 when it is in the open position, there is no need to additionally increase the volume of the first chamber 110 and / or the second chamber 310 to facilitate mixing between medicines during manufacturing. It is only necessary to control the volume 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 medicine packaging device can be reduced.

[0063] The operation process of the medicine 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 the movable part 300 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 the movable part 300 to the closed position, at this time, the first chamber 110 stores a mixed medicine mixed with the first material and the second material; 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. The partition 210 is located inside the cavity. The partition 210 and the inner wall of the cavity form a first chamber 110, wherein the first chamber 110 is a part of the cavity.

[0065] like Figure 2-Figure 6 As shown, the connector 200 further 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 sealedly connected 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 disposed on the outer wall of the shell 220 , and a second assembly structure is disposed 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, so that the bottle body 100 and the connector 200 are connected by threaded connection. The cooperation between the external thread and the internal thread also achieves a sealing effect.

[0068] In other embodiments, in the first assembly structure and the second assembly structure, one is a buckle and the other is a slot, so that the bottle body 100 and the connector 200 are connected by snap connection. For sealing effect, a sealing ring or a 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, etc.

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

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

[0071] like Figure 4 and Figure 6 As shown, the movable member 300 includes a sealing portion 320, which is arranged around the second chamber 310. The sealing portion 320 is used to seal the flow structure 2121, wherein the outer surface of the sealing portion 320 is a conical surface. The shape of the inner wall of the cover body 212 is adapted to the outer surface of the sealing portion 320, and is also a conical surface.

[0072] When the movable member 300 is in the closed position, the outer surface of the closing portion 320 is sealed against the inner wall of the cover body 212. Since the outer surface of the closing portion 320 and the inner wall of the cover body 212 are tapered, the two can fit closely and achieve sealing.

[0073] When the movable part 300 is in the open position, there is a gap between the sealing part 320 and the cover body 212 along the preset direction. The first chamber 110, the circulation chamber 213 and the second chamber 310 are sequentially distributed along the preset direction, so that the space for mixing the first material and the second material is increased, so that the first material and the second material can move and mix in the first chamber 110, the circulation chamber 213 and the second chamber 310, ensuring that the first material and the second material can be fully and efficiently mixed within a sufficient aperture. Since the first chamber 110, the circulation chamber 213 and the second chamber 310 are sequentially distributed and connected along the preset direction, when mixing the medicines, refer to Figure 2 , you only need to hold the bottle body 100 and shake it along the height direction of the bottle body 100, which is convenient to hold and more labor-saving to operate.

[0074] In this embodiment, the movable member 300 further includes a main body 330, and the housing 220 is sleeved on the main body 330. The main body 330 and the housing 220 are movably and sealedly connected. When the main body 330 and the housing 220 are rotationally connected, the main body 330 and the housing 220 can be sealed by a threaded connection; when the main body 330 and the housing 220 are slidingly connected, the main body 330 and the housing 220 can be sealed by a sealing member such as a sealing ring.

[0075] Among the housing 220 and the body 330 , one is provided with a positioning portion, and the other is provided with a matching portion 420 .

[0076] In this embodiment, the positioning portion is disposed on the housing 220, and the matching portion 420 is disposed on the main body 330. In other embodiments, the positioning portion can be disposed on the main body 330, and the matching portion 420 can be disposed on the housing 220 as required.

[0077] like Figure 3 and Figure 5 As shown, the positioning portion 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 matching portion 420 to position the main body 330 so that the movable member 300 is in the closed position; the second positioning structure 412 is used to cooperate with the matching portion 420 to position the main body 330 so that the movable member 300 is in the open position.

[0079] The main body 330 is positioned by the first positioning structure 411 and the second positioning structure 412. When the user moves the main body 330, the matching portion 420 cooperates with the first positioning structure 411 or the second positioning structure 412, so that the main body 330 can be accurately moved 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 member 300 is in the open position, the flow cavity 213 is located inside the partition 210 , thereby achieving full utilization of the internal space of the partition 210 .

[0081] In this embodiment, the first positioning structure 411 and the second positioning structure 412 are both 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 linear.

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

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

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

[0085] like Figure 2-Figure 6 As shown, an exposed portion 340 is provided at one end of the main body 330 away from the closed portion 320, and the exposed portion 340 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-skid structure for increasing friction, and the anti-skid structure can be a pattern, a groove or a coating. When it is necessary to drive the movable part 300 to move, the user can hold the bottle body 100 with one hand and the exposed portion 340 with the other hand. Then, by rotating the movable part 300, the movable part 300 can be moved to the open position or the closed position. The anti-skid structure can play an anti-skid role to avoid slipping during operation.

[0086] A hollow cavity 331 is provided inside the main body 330, and ribs 332 are provided 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 push-type spray head 500 is disposed on the bottle body 100 , and a straw 507 of the push-type spray head 500 is located in the first chamber 110 .

[0088] A concave portion 2111 is provided on the side of the connecting member 200 facing away from the second chamber 310, wherein the suction tube 507 is partially located in the concave portion 2111, and there is a gap between the suction tube 507 and the connecting member 200. Such a structural arrangement allows the suction tube 507 to be as close to the bottom of the first chamber 110 as possible, so that the mixed medicine at the bottom of the first chamber 110 can be sucked, thereby 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 spray head 500 includes a mounting cover 501 , a bracket 502 , a pressing member 503 , a mounting tube 504 , a piston 505 , a storage cylinder 506 , a suction tube 507 and a nozzle 508 .

[0090] The mounting cover 501 is mounted on the bottle mouth of the bottle body 100 , the bracket 502 is fixedly disposed inside the mounting cover 501 , and the pressing piece 503 is fixedly connected to the mounting tube 504 .

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

[0099] After the first material and the second material are mixed, the pressing member 503 is pressed, the mounting tube 504, the core rod 509 and the piston 505 all move downward, and the volume of the cavity 516 is reduced. Accordingly, the first spring 513 and the second spring 518 are both compressed. At this time, the pressure in the cavity 516 increases, so that the movable ball 517 closes the passage between the storage tube 506 and the straw 507; at the same time, under the action of air pressure, the air in the cavity 516 pushes the piston 505 to move upward, so that the passage gap 512 is opened, so that the air 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 in sequence; when the air pressure in the cavity 516 is reduced to a certain value, the piston 505 moves downward under the action of the first spring 513, so that the passage gap 512 is re-closed. The pressure on the pressing piece 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 member 503 for multiple times, the air in the cavity 516 can be exhausted as much as possible, thereby forming a vacuum environment in the cavity 516 .

[0101] When a vacuum environment is formed in the cavity 516, the mixed medicine in the first chamber 110 is sucked into the straw 507 under the action of negative pressure, and pushes the movable ball 517 to enter the cavity 516. Then, by pressing the pressing member 503, the mixed medicine 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 in sequence, so as to be used by the user.
