Technical Field

[0001] This application relates to the field of medical device technology, specifically to a ball valve bottle cap and a sealed powder bottle. Background Technology

[0002] The storage and handling of powdered pharmaceutical preparations require extremely high standards of safety, accuracy, and hygiene. In clinical use, the dosage of powdered drugs must be strictly controlled for different symptoms to ensure efficacy and avoid the risk of overdose. At the same time, the characteristics of powdered drugs, such as being prone to moisture absorption, clumping, contamination, and deterioration, require that storage containers have reliable sealing during handling to isolate them from external moisture, microorganisms, and dust.

[0003] However, in related technologies, the storage method for medicine powder usually uses wide-mouth bottles. Each time medicine is taken out, the bottle cap needs to be opened and a small spoon is used to scoop out an appropriate amount of medicine powder. This can easily cause the medicine powder to become damp, clump, mold, and deteriorate. Moreover, the process of opening the bottle cap and using a small spoon to scoop out medicine each time is cumbersome. Utility Model Content

[0009] Optionally, the valve housing assembly is a cylindrical sleeve structure, and one end of the valve housing assembly is provided with an annular flange extending toward the center of the valve housing assembly. The hollow portion of the annular flange forms the first opening. The inner diameter of the first opening is equal to the outer diameter of the receiving cavity opening. When the ball valve assembly is rotated to the first position, the opening of the receiving cavity coincides with the first opening.

[0010] When the ball valve assembly is rotated to the second position, the bottom of the receiving cavity protrudes from the annular flange; the ball valve assembly is movably and sealingly connected to the annular flange.

[0011] Optionally, the handle assembly includes a first connector and a handle; the ball valve assembly has a groove, and the valve housing assembly has a second through hole at a position corresponding to the groove; one end of the first connector passes through the second through hole and extends into the groove to be fixedly connected to the ball valve assembly, and the other end of the first connector is fixedly connected to the handle. On the other hand, this application provides a sealed powder bottle, the powder bottle including: a bottle body assembly and a ball valve type cap as described in any of the above claims; the valve housing assembly is fixedly connected to the bottle body assembly.

[0012] Optionally, the bottle assembly is rotatably and sealingly connected to the ball valve assembly, and the bottle assembly is fixedly and sealingly connected to the valve housing assembly; the receiving cavity is used to temporarily store the powder entering from the bottle assembly; when the ball valve assembly is in the first position, the opening of the receiving cavity is away from the opening of the bottle assembly and coincides with the first opening; when the ball valve assembly is in the second position, the opening of the receiving cavity coincides with the opening of the bottle assembly.

[0013] Optionally, the bottle assembly includes a bottle body and a connecting cap; one end of the connecting cap is connected to a ball valve type bottle cap, and the other end of the connecting cap is rotatably connected to the bottle body.

[0014] Optionally, the powder bottle further includes a cap; the cap is provided with an annular protrusion close to the ball valve assembly along the axial direction of the valve housing assembly at the connection point with the valve housing assembly, and an annular plane is provided at one end of the valve housing assembly connected to the cap, which is radially away from the ball valve assembly; the cap is used to press the annular plane and the annular protrusion together along the radial direction of the valve housing assembly.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] like Figures 1 to 2 As shown, this application provides a ball valve bottle cap, which includes: a ball valve assembly 10, a valve housing assembly 20, and a handle assembly 30; the ball valve assembly 10 is disposed in the valve housing assembly 20 and is rotatably and sealingly connected to the valve housing assembly 20; the handle assembly 30 is fixedly connected to the ball valve assembly 10; the valve housing assembly 20 includes a first opening 201; the ball valve assembly 10 includes a receiving cavity 101 for temporarily storing powder; the handle assembly 30 is used to drive the ball valve assembly 10 to rotate around the axis where the connection point between the handle assembly 30 and the ball valve assembly 10 is located; when the handle assembly 30 drives the ball valve assembly 10 to rotate to a first position, the opening of the receiving cavity 101 coincides with the first opening 201; when the handle assembly 30 drives the ball valve assembly 10 to rotate to a second position, the bottom of the receiving cavity 101 blocks the first opening 201.

[0028] Specifically, the ball valve cap includes a ball valve assembly 10, a valve housing assembly 20, and a handle assembly 30. This ball valve cap can be used for powder bottles. The valve housing assembly 20 is fixedly connected to the powder bottle, and the ball valve assembly 10 is rotatably and sealingly connected to the powder bottle. The ball valve assembly 10 is housed within the valve housing assembly 20 and is movably and sealingly connected to it. The handle assembly 30 is fixedly connected to the ball valve assembly 10, and the ball valve assembly 10 can rotate within the valve housing assembly 20 under the actuation of the handle assembly 30. The ball valve assembly 10 has a receiving cavity 101 for temporarily storing powder entering from the powder bottle, and the valve housing assembly 20 has a first opening 201. When the handle assembly 30 drives the ball valve assembly 10 to rotate to the first position, the opening of the receiving cavity 101 coincides with the first opening 201, allowing the powder temporarily stored in the receiving cavity 101 to be poured out. When the handle assembly 30 drives the ball valve assembly 10 to rotate to the second position, the bottom of the receiving cavity 101 blocks the first opening 201, thereby achieving a seal on the bottle cap.

[0029] When medication is not needed, the ball valve assembly 10 is in the second position to ensure the cap is sealed and prevent dust or moisture from entering the powder bottle and causing the powder to become damp. When medication needs to be dispensed, the powder bottle can be inverted, and the powder enters the receiving cavity 101. Then, the handle assembly 30 is turned to rotate the ball valve assembly 10 to the first position, aligning the opening of the receiving cavity 101 with the opening of the valve housing assembly 20. The powder temporarily stored in the receiving cavity 101 is then poured out. After dispensing the medication, the ball valve assembly 10 is turned back to the second position using the handle assembly 30 to ensure the cap is sealed.

[0030] Understandably, the ball valve cap design, through the movable sealing connection between the ball valve assembly 10 and the valve housing assembly 20, and the design of the handle assembly 30 driving the ball valve assembly 10 to rotate, effectively solves the problems of moisture absorption, contamination, and cumbersome handling when storing powdered medicine in traditional wide-mouth bottles. Specifically, the receiving cavity 101 of the ball valve assembly 10 can temporarily store powdered medicine. By rotating the handle 302 to switch between the first and second positions, the temporary storage and release of powdered medicine can be achieved without fully opening the cap. When the opening of the receiving cavity 101 coincides with the first opening 201 of the valve housing assembly 20, the output of powdered medicine can be precisely controlled. When rotated to the second position, the bottom sealing opening forms a seal, isolating external moisture, microorganisms, and dust, ensuring the safety and hygiene of the stored powdered medicine. This structure avoids the cumbersome operation of frequently opening the cap and using a small spoon to scoop out the powder, simplifying the handling process. At the same time, the rotation action enables precise control of the temporary storage and release of powdered medicine, meeting the clinical medication requirements for dosage accuracy, reducing the risk of contamination, and improving ease of use. Optionally, as... Figures 2 to 3 As shown, the ball valve assembly 10 also includes an adjustment mechanism 102; the adjustment mechanism 102 is used to adjust the size of the receiving cavity 101.

[0031] Specifically, the ball valve assembly 10 also includes an adjustment mechanism 102, which is used to adjust the size of the receiving cavity 101 to adjust the amount of powder dispensed each time.

[0032] In some embodiments, the adjustment mechanism 102 includes an elastic sleeve and an adjustment knob nested within the receiving cavity 101. One end of the elastic sleeve is fixed to the inner wall of the receiving cavity 101, and the other end is connected to the adjustment knob via a radial telescopic structure. When the adjustment knob is rotated, the elastic sleeve expands or contracts radially, thereby changing the volume of the receiving cavity 101.

[0033] In other embodiments, the adjustment mechanism 102 includes multiple replaceable modular volume blocks and positioning latches. The inner wall of the receiving cavity 101 is provided with an annular groove, and the modular volume blocks are detachably connected to the groove via the positioning latches. Each volume block has a different volume, and replacing different volume blocks can change the volume of the receiving cavity 101.

[0034] Understandably, the adjustment mechanism 102 can flexibly adjust the volume of the receiving cavity 101 according to actual needs, thereby achieving precise control over the temporary storage dose of the powder. By changing the space of the receiving cavity through the adjustment mechanism 102, it can adapt to the single-dose requirements of different drugs (such as small doses for children and regular doses for adults), avoiding the dosage deviation or cumbersome operation problems caused by traditional medicine bottles relying on external tools for scooping. At the same time, the ball valve assembly 10 and the valve shell assembly 20 can be kept sealed during the adjustment process to prevent the powder from getting damp or contaminated during adjustment, ensuring storage hygiene. This design also improves the versatility of the bottle cap, making it suitable for the storage and use of various powder preparations, especially suitable for clinical scenarios with high dosage accuracy requirements or scenarios requiring personalized medication.

[0035] Optionally, such as Figures 2 to 3 As shown, the adjustment mechanism 102 includes an adjustment plate 1021 and an adjustment bolt 1022; the adjustment plate 1021 is movably connected to the side wall of the receiving cavity 101; the adjustment plate 1021 has a first through hole 10211 that cooperates with the adjustment bolt 1022, the adjustment bolt 1022 passes through the first through hole 10211, and the adjustment bolt 1022 is used to adjust the position of the adjustment plate 1021 on the side wall of the receiving cavity 101.

[0036] Understandably, within the receiving cavity 101 of the ball valve assembly 10, the adjusting plate 1021 is interference-fitted with the inner wall of the receiving cavity 101, so that the adjusting plate 1021 can be engaged in the receiving cavity 101 and will not slide down under gravity. The adjusting plate 1021 is disc-shaped and its edge forms a sealing fit with the side wall of the receiving cavity to ensure that the powder does not leak. A first through hole 10211 with internal threads is opened in the center of the adjusting plate 1021. This first through hole 10211 is a threaded through hole that mates with the adjusting bolt 1022. An adjusting bolt 1022 is vertically inserted into the first through hole 10211. When it is necessary to adjust the position of the adjusting plate 1021 in the receiving cavity 101, one end of the adjusting bolt 1022 is inserted into the first through hole 10211, and the other end of the adjusting bolt 1022 is pulled or pushed to push the adjusting plate 1021 into or out of the receiving cavity 101, thereby adjusting the volume of the receiving cavity. After each adjustment of the adjusting plate 1021 by the adjusting bolt 1022, the adjusting bolt 1022 is removed to ensure that the adjusting bolt 1022 does not affect the rotation of the ball valve assembly 10 within the valve body assembly 20. The diameter of the first through hole 10211 is smaller than a preset value, which can be 2mm-5mm, such as 3mm or 4mm, so that even after the adjusting bolt 1022 is removed, the amount of powder leaking out of the first through hole 10211 is negligible. The adjusting plate 1021 is interference-fitted with the side wall of the receiving cavity 101 so that the adjusting plate 1021 will not fall off due to gravity after the adjusting bolt 1022 is removed. The adjusting plate 1021 can be made of rigid plastic plate or metal plate, and the embodiments of this application do not limit it.

[0037] Understandably, the adjustment mechanism 102, through the cooperation of the adjustment plate 1021 and the adjustment bolt 1022, realizes the adjustment of the volume of the receiving cavity 101, effectively solving the needs of different drug dosage differences. By pushing or pulling the adjustment bolt 1022 to drive the adjustment plate 1021 to slide along the side wall, the size of the receiving cavity space can be continuously adjusted to meet the flexible switching of dosage and improve the versatility of the bottle cap; this structure can maintain the adjustment position without additional locking devices, and by utilizing the frictional resistance of the contact surface, it can still reliably position itself when the medicine bottle is inverted or vibrated, avoiding accidental changes in dosage; the movable sealing design of the adjustment plate 1021 and the side wall maintains the sealing of the medicine powder during the adjustment process, preventing moisture or contamination, which is especially suitable for the storage of humidity-sensitive drugs.

[0038] Optionally, such as Figures 2 to 4As shown, the valve housing assembly 20 is a cylindrical sleeve structure. One end of the valve housing assembly 20 is provided with an annular flange 2011 extending toward the center of the valve housing assembly 20. The hollow part of the annular flange 2011 forms a first opening 201. The inner diameter of the first opening 201 is equal to the outer diameter of the opening of the receiving cavity 101. When the ball valve assembly 10 is rotated to the first position, the opening of the receiving cavity 101 coincides with the first opening 201. When the ball valve assembly 10 is rotated to the second position, the bottom of the receiving cavity 101 protrudes from the annular flange 2011. The ball valve assembly 10 and the annular flange 2011 are movably and sealingly connected.

[0039] Specifically, the valve housing assembly 20 is configured as a cylindrical sleeve structure, and the ball valve assembly 10 is housed in the sleeve structure. One end of the valve housing assembly 20 is provided with an annular flange 2011 extending toward the center of the valve housing assembly 20. The hollow part of the annular flange 2011 forms a first opening 201. The inner diameter of the first opening 201 is equal to the outer diameter of the opening of the receiving cavity 101, so as to ensure that the powder can pass smoothly through the opening when it is released, and to avoid the risk of jamming or leakage due to size deviation.

[0040] The valve housing assembly 20 may be made of rigid plastic or metal materials, and the embodiments of this application do not limit it.

[0041] In some embodiments, the valve housing assembly 20 is made of medical-grade polypropylene with a smooth inner wall and antibacterial treatment to prevent powder contamination or residue. Its annular flange can be integrally cast, and its inner diameter is designed to be equal to the outer diameter of the opening of the receiving cavity 101 of the ball valve assembly 10, ensuring that the powder can pass through without obstruction when the two overlap. An annular groove is provided at the contact point between the outer surface of the ball valve assembly 10 and the inner side of the annular flange 2011, with an embedded sealing ring to form a sliding sealing pair, allowing the ball valve assembly 10 to rotate while isolating external moisture.

[0042] When taking the medicine, the ball valve assembly 10 rotates to the first position, and the opening of the receiving cavity 101 coincides with the first opening 201, so that the medicine powder temporarily stored in the receiving cavity 101 is poured out; after taking the medicine, when the ball valve assembly 10 rotates to the second position, the arc-shaped surface of the bottom of the valve ball of the receiving cavity 101 protrudes from the annular flange 2011, completely blocking the first opening 201 on the annular flange 2011. The ball valve assembly 10 and the annular flange 2011 are movably and sealingly connected, preventing external pollutants and moisture from entering.

[0043] Understandably, the valve housing assembly 20 adopts a cylindrical sleeve structure. One end of the valve housing assembly 20 is provided with an annular flange 2011 extending towards the center of the valve housing assembly 20. The rotation of the ball valve assembly 10 can flexibly switch between the temporary storage and sealing states of the medicine powder: when the ball valve assembly 10 is rotated to the first position, the opening of the receiving cavity 101 coincides with the first opening 201, which facilitates the smooth access of the medicine powder through the opening. The structural size adaptation ensures that the medicine powder flows smoothly without jamming. When rotated to the second position, the annular flange 2011 protrudes from the bottom of the ball valve assembly 10, which can effectively block the opening. Combined with the movable sealing connection structure, it can reliably isolate external moisture, dust and microorganisms, prevent the medicine powder from getting damp or contaminated, and ensure the sealing and hygiene during storage. The state can be switched by a simple rotation operation, without complicated disassembly and assembly steps, making it convenient to use. At the same time, the precise cooperation between the annular flange 2011 and the ball valve assembly 10 enables reliable control of the release and sealing of the powder, meeting the dual requirements of powder preparations for storage safety and ease of use.

[0044] Optionally, such as Figures 2 to 4 As shown, the handle assembly 30 includes a first connector 301 and a handle 302; the ball valve assembly 10 has a groove 103, and the valve housing assembly 20 has a second through hole 202 at a position corresponding to the groove 103. One end of the first connector 301 passes through the second through hole 202 and extends into the groove 103 to be fixedly connected to the ball valve assembly 10, and the other end of the first connector 301 is fixedly connected to the handle 302.

[0045] Specifically, the handle assembly 30 includes a first connector 301 and a handle 302. One end of the first connector 301 passes through the second through hole 202 of the valve housing assembly 20 and extends into the groove 103, and is fixedly connected to the ball valve assembly 10. The other end of the first connector 301 is fixedly connected to the handle 302.

[0046] In some embodiments, the end of the first connector 301 connected to the ball valve assembly 10 is a flat key head. A keyway adapted to the flat key head is provided at the bottom of the groove 103 where it abuts against the first connector 301. The flat key head is inserted into the keyway to fix the first connector 301 to the ball valve assembly 10. In other embodiments, the end of the first connector 301 connected to the ball valve assembly 10 is a flat key head adapted to the groove 103. The flat key head is inserted into the groove 103 to fix the first connector 301 to the ball valve assembly 10. The end of the first connector 301 connected to the handle 302 is a spline. The connection point between the handle 302 and the first connector 301 is a spline sleeve adapted to the spline. The spline sleeve connects the first connector 301 to the handle 302. In other embodiments, the handle 302 is provided with a sleeve portion into which the first connector 301 can be inserted. The sleeve portion of the handle 302 is sleeved on the first connector 301. A screw hole is provided at the end of the first connector 301 that connects to the handle 302. The first connector 301 and the handle 302 are then secondary fixed by a nut and the screw hole. It can be understood that the handle assembly 30 is radially connected to the ball valve assembly 10 through the first connector 301, thereby achieving reliable driving and precise control of the rotational movement of the ball valve assembly 10. The first connector 301 passes through the second through hole 202 of the valve housing assembly 20 and extends into the groove 103 of the ball valve assembly 10, forming a stable rotating shaft structure. This ensures that the torque is effectively transmitted to the ball valve assembly 10 when the handle 302 is rotated, preventing slippage or loosening. This structure hides the drive mechanism inside the valve housing, reducing the risk of external contamination and preventing powder from contacting the connector, thus extending its service life. The groove 103 increases the contact area between the connector and the ball valve assembly 10, improving the connection strength and allowing it to withstand frequent rotation without failure. While simplifying the operation process, it ensures the stability and sealing of the ball valve assembly 10's rotation, improving the reliability and hygiene safety of the medicine bottle.

[0047] On the other hand, such as Figures 1 to 4 As shown, this application also provides a sealed powder bottle, which includes: a bottle body assembly 40 and a ball valve type bottle cap as described in any of the above claims; the valve housing assembly 20 is fixedly connected to the bottle body assembly 40.

[0048] Understandably, this application also provides a sealed powder bottle, which includes a bottle body assembly 40 and a ball valve cap as described in any of the above claims. The sealed powder bottle, through the fixed connection design between the bottle body assembly 40 and the ball valve cap, achieves efficient sealing and convenient operation for powder storage and retrieval: the fixed connection between the bottle body assembly 40 and the valve housing assembly 20 forms a stable mechanical support, ensuring the ball valve assembly 10 is stable and reliable when rotating and switching states. The sealed connection structure between the two effectively blocks external moisture, dust, and microorganisms from intruding, preventing the powder from becoming damp, clumping, or contaminated. The receiving cavity 101 of the ball valve cap can temporarily store the powder entering from the bottle body assembly 40. By rotating the handle 302, the overlap or separation of the opening of the receiving cavity and the opening of the bottle body 401 can be controlled, allowing for quantitative dispensing of the powder without fully opening the cap, reducing the frequency of contact between the powder and the outside environment, and ensuring hygiene during storage.

[0049] Optionally, the bottle assembly 40 is movably and sealingly connected to the ball valve assembly 10, and the bottle assembly 40 is fixedly and sealingly connected to the valve housing assembly 20; the receiving cavity 101 is used to temporarily store the powder entering from the bottle assembly 40; when the ball valve assembly 10 is in the first position, the opening of the receiving cavity 101 is away from the opening of the bottle assembly 40 and coincides with the first opening 201; when the ball valve assembly 10 is in the second position, the opening of the receiving cavity 101 coincides with the opening of the bottle assembly 40.

[0050] Specifically, the ball valve cap is movably and sealingly connected to the ball valve assembly 10. When the ball valve assembly 10 is in the second position, the opening of the receiving cavity 101 coincides with the opening of the bottle body assembly 40. The opening of the receiving cavity 101 is smaller than the opening of the bottle body assembly 40 by a preset value, so that the powder can enter the receiving cavity 101 from the bottle body assembly 40. The bottle body assembly 40 is fixedly and sealingly connected to the valve housing assembly 20. When the ball valve assembly 10 is in the first position, the opening of the receiving cavity 101 coincides with the first opening 201 of the valve housing assembly 20.

[0051] Understandably, the sealed powder bottle, through the design of the bottle body assembly 40 and the ball valve cap, achieves full-process sealed control of powder storage, temporary storage, and retrieval: the movable sealing connection between the bottle body assembly 40 and the ball valve assembly 10, and the fixed sealing connection with the valve shell assembly 20, form a double sealing barrier, effectively isolating external moisture, dust, and microorganisms, and preventing the powder from absorbing moisture, clumping, or becoming contaminated; the receiving cavity 101 serves as a temporary storage space, which can overlap with the opening of the bottle body assembly 40 when the ball valve assembly 10 is in the second position, allowing the powder to directly enter the receiving cavity from the bottle body 401; when rotated to the first position, the connection with the bottle body 401 is cut off, ensuring that the cap does not need to be fully opened during retrieval, reducing the frequency of powder contact with the outside world; this structure can switch between sealing and releasing states by driving the valve ball to rotate through the handle 302, which is simple to operate and avoids the cumbersome steps of scooping with tools required by traditional medicine bottles. At the same time, the precise positioning of the ball valve assembly 10 can control the amount of powder temporarily stored at one time, meeting the needs of dosage adjustment and hygiene safety in different scenarios.

[0052] Optionally, such as Figures 1 to 2 As shown, the bottle assembly 40 includes a bottle body 401 and a connecting cap 402; one end of the connecting cap 402 is connected to a ball valve type bottle cap, and the other end of the connecting cap 402 is rotatably connected to the bottle body 401.

[0053] Specifically, the bottle assembly 40 includes a bottle body 401 and a connecting cap 402. One end of the connecting cap 402 is rotatably connected to the bottle body 401, and the other end is connected to a ball valve type bottle cap. One end of the connecting cap 402 is fixedly and sealed to the bottle cap, and the other end is rotatably engaged with the bottle body 401, allowing the bottle body 401 to rotate relative to the bottle cap, which facilitates the filling of medicine powder. The fixed sealing design of the connecting cap 402 and the bottle cap ensures no leakage during rotation, while the rotational sealing structure between the bottle body 401 and the connecting cap 402 can effectively block external moisture, providing a more reliable storage environment for the medicine powder.

[0054] Optionally, such as Figures 1 to 2 As shown, the connecting cap 402 is a funnel-shaped structure with its diameter gradually decreasing from the end near the bottle body 401 to the end away from the bottle body 401 along the axial direction of the connecting cap 402; the opening on the side of the connecting cap 402 away from the bottle body 401 is rotatably and sealingly connected to the ball valve assembly 10, and the side of the connecting cap 402 near the ball valve assembly 10 is fixedly connected to the valve housing assembly 20; when the ball valve assembly 10 rotates to the first position, the opening of the receiving cavity 101 is away from the opening of the connecting cap 402; when the ball valve assembly 10 rotates to the second position, the opening of the receiving cavity 101 coincides with the opening of the connecting cap 402.

[0055] Specifically, the connecting cap 402 is a funnel-shaped structure with its diameter gradually decreasing from the end near the bottle body 401 to the end away from the bottle body 401 along the axial direction of the connecting cap 402, so as to facilitate the entry of the medicine powder from the bottle body 401 into the receiving cavity 101. The opening of the connecting cap 402 away from the bottle body 401 is rotatably and sealingly connected to the ball valve assembly 10, so that the ball valve assembly 10 can rotate at the opening of the connecting cap 402 away from the bottle body 401. The side of the connecting cap 402 near the ball valve assembly 10 is fixedly connected to the valve housing assembly 20, providing a limit for the ball valve assembly 10 in the axial direction of the bottle body 401. When the ball valve assembly 10 is rotated to the second position, the opening of the receiving cavity 101 coincides with the opening of the connecting cap 402. Inverting the bottle body 401 allows the medicine powder to enter the receiving cavity 101 from the bottle body 401 through the connecting cap 402. Continue rotating the ball valve assembly 10. When the ball valve assembly 10 is rotated to the first position, the opening of the receiving cavity 101 moves away from the opening of the connecting cover 402 and coincides with the first opening 201 of the valve housing assembly 20, thus pouring out the powder.

[0056] Understandably, the funnel-shaped structure of the cap 402, in conjunction with the ball valve assembly 10, enables efficient transfer and reliable sealing of the powder between the bottle body 401 and the receiving cavity: the axially tapering funnel shape of the cap 402 can utilize gravity to guide the powder smoothly into the receiving cavity 101 of the ball valve assembly 10, reducing powder retention and accumulation, especially suitable for powders with poor flowability; the end of the cap 402 away from the bottle body 401 is rotatably and sealingly connected to the ball valve assembly 10, ensuring that when the valve ball rotates to switch between the first and second positions, it can achieve rapid filling of the powder through the overlapping of the openings, and can also isolate the internal and external environments of the bottle by means of the sealing structure during separation, preventing moisture and dust from entering; the end closer to the ball valve assembly 10 is fixedly connected to the valve shell, forming a stable mechanical support, making the rotation operation smoother. This design allows for temporary storage of medicine powder without tilting or inverting the bottle 401, simplifying the retrieval process. At the same time, the funnel-guided flow and precise opening alignment improve the efficiency of medicine powder transfer. Combined with the rotating sealing structure, it effectively ensures the airtightness and hygiene during storage, reducing the risk of medicine powder getting damp or contaminated.

[0057] Optionally, such as Figures 2 to 5 As shown, the powder bottle also includes a cap 403; the connection between the cap 402 and the valve housing assembly 20 is provided with an annular protrusion 4021 that is close to the ball valve assembly along the axial direction of the valve housing assembly 20, and the end of the valve housing assembly 20 that is connected to the cap 402 is provided with an annular plane 203 that is radially away from the ball valve assembly 10 along the valve housing assembly 20; the cap 403 is used to press the annular plane 203 and the annular protrusion 4021 together along the radial direction of the valve housing assembly 20.

[0058] Specifically, at the connection between the cap 402 and the valve housing assembly 20, an annular protrusion 4021 is provided along the axial direction of the valve housing assembly 20, close to the ball valve assembly, to provide effective support for the valve housing assembly 20. At one end of the valve housing assembly 20 where it connects to the cap 402, an annular plane 203 is provided along the radial direction of the valve housing assembly 20, away from the ball valve assembly 10. This annular plane 203 and the annular protrusion 4021 are fitted together along the radial direction of the valve housing assembly 20. The powder bottle also includes a pressure cap 403, which is used to press the annular plane 203 and the annular protrusion 4021 together along the radial direction of the valve housing assembly 20, ensuring a tight seal and a secure connection between the cap 402 and the valve housing assembly 20.

[0059] In some embodiments, the gland 403 and the annular protrusion 4021 are connected by threads along the planes extending in the axial direction of the valve housing assembly 20. In other embodiments, the gland 403 and the annular plane 203 and the annular protrusion 4021 are connected along the planes extending in the radial direction of the valve housing assembly 20 by screws or adhesive materials. This application does not limit the specific connection methods.

[0060] Understandably, the cap 403, through the radial pressing of the annular protrusion 4021 and the annular plane 203, achieves a reliable and secure seal between the cap 402 and the valve housing assembly 20. The cap 403 radially presses the annular plane 203 of the valve housing assembly 20 and the annular protrusion 4021 of the cap 402 together, forming a tight planar seal structure. This effectively prevents external moisture, dust, and microorganisms from entering the bottle through the connection, avoiding moisture or contamination of the powder. This pressing method eliminates the need for complex threaded or glued seals, simplifying the assembly process and improving efficiency. While ensuring production efficiency, it also guarantees reliable sealing and facilitates subsequent disassembly and maintenance. The radial pressing design precisely fixes the relative position of the cap 402 and the valve housing assembly 20, preventing loosening due to long-term use or vibration, and ensuring the stability of the ball valve assembly 10 when rotating and switching positions. Compared with traditional point contact seals, the planar sealing structure has a larger contact area and a more uniform sealing effect, which is especially suitable for the high requirements of the storage environment for powdered pharmaceutical preparations, providing long-term reliable sealing for medicine bottles, extending the shelf life of the powder and improving the safety of use.

[0061] Optionally, such as Figure 5 As shown, the pressure cap 403 also includes a gasket 4031; the gasket 4031 is placed between the annular top plate and the annular plane 203.

[0062] Specifically, the gasket 4031 is made of silicone or rubber, and this application embodiment does not limit its use. In some embodiments, the gland 403 is injection molded from medical-grade polypropylene, and its inner side is provided with a circular groove adapted to the size of the annular plane 203. An annular gasket 4031 made of silicone is placed in the groove. The outer diameter of the gasket 4031 is consistent with the outer diameter of the annular protrusion 4021 of the connecting cover 402, and the inner diameter is slightly larger than the axial through hole of the valve housing assembly 20. During assembly, the annular protrusion 4021 of the connecting cover 402 is aligned with the annular plane 203 of the valve housing assembly 20, so that the gasket 4031 completely covers the contact area of ​​the two. Then, the gasket 4031 is pressed between the annular plane 203 and the protrusion by tightening the internal thread of the edge of the gland 403 and the external thread of the valve housing assembly 20.

[0063] Understandably, the gasket 4031 significantly improves the overall sealing of the medicine bottle; it can effectively block external moisture for hygroscopic drugs; at the same time, the cushioning effect of the gasket 4031 can reduce the rigid contact when the cap 403 is connected to the valve housing assembly 20, avoid wear or cracks caused by long-term tightening, and extend the service life of the sealing structure.

[0064] Optionally, the ball valve assembly 10 and the handle assembly 30 are integral structures; and / or, the valve housing assembly 20 and the mandrel 402 are integral structures.

[0065] Specifically, the ball valve assembly 10 and the handle assembly 30 are manufactured as a single piece using an integral molding process. During manufacturing, the ball valve assembly 10 and the handle assembly 30 can be integrally molded first, then the integral structure of the ball valve assembly 10 and the handle assembly 30 can be placed into the mold of the valve body assembly 20. The valve body assembly 20 is then machined based on this integral structure. The ball valve cap can be integrally injection molded from plastic material, and this application does not limit its application. It is understood that when the ball valve assembly 10 includes an adjusting mechanism 102, after the ball valve assembly 10 and the handle assembly 30 are integrally molded, the adjusting mechanism 102 is installed first, and then the valve body assembly 20 is machined.

[0066] Furthermore, the valve housing assembly 20 and the connecting cap 402 can also be a one-piece structure manufactured using an integral molding process. During manufacturing, the ball valve assembly 10 and the handle assembly 30 can be integrally molded first, and then the integrated structure of the ball valve assembly 10 and the handle assembly 30 can be placed into an integrated mold for the valve housing assembly 20 and the connecting cap 402. The integrated structure of the valve housing assembly 20 and the connecting cap 402 can then be processed based on the integrated structure of the ball valve assembly 10 and the handle assembly 30. The sealed powder bottle can be integrally injection molded from plastic material; this application does not limit its application.

[0067] Understandably, the integrated structure eliminates the connection gaps of detachable components. Combined with a high-precision sealing design, it achieves a fully enclosed seal, significantly reducing the probability of the powder coming into contact with external air and moisture. This reduces the risk of the powder becoming damp, clumping, moldy, or deteriorating, effectively extending the shelf life of the powder. The precise dispensing of the powder can be controlled by rotating the ball valve assembly 10, eliminating the need to frequently open the bottle cap or use a small spoon to scoop it out, greatly improving the convenience of dispensing the medicine. The overall structure design without redundant interfaces has a smooth and flat surface, making it less likely for powder residue to remain, facilitating cleaning and disinfection, and reducing the risk of cross-contamination. In addition, the one-piece, non-detachable nature avoids problems such as loosening or loss of bottle cap components, ensuring long-term stable sealing performance. It is especially suitable for pharmaceutical scenarios with extremely high requirements for moisture and contamination prevention, providing a safer and more efficient solution for the storage and retrieval of powder.
