Description

Technical Field

[0001] This utility model relates to the field of medicine bottle technology. Background Technology

[0002] Chinese invention patent CN116353959B discloses a medicine bottle, which includes a bottle body, a dispensing cap, a dispensing cap, a push cap, and a top cap arranged sequentially from bottom to top. The bottle body is divided into multiple independent medicine slots arranged circumferentially by multiple partitions. The dispensing cap is fixedly connected to the bottle body and has multiple dispensing ports arranged circumferentially. The dispensing cap is rotatably mounted on the dispensing cap and has a dispensing port. The push cap is mounted on the dispensing cap and can slide between a blocking position and an open position along the diameter of the dispensing cap. When the push cap is in the blocking position, it blocks the dispensing port. When the push cap is in the open position, the dispensing port is opened.

[0003] When a user needs to place medication into the medicine bottle, they must open the bottle between the body and the dispensing cap to expose the medication compartment. In the medicine bottle disclosed in CN116353959B, the dispensing cap is connected to the bottle body via upper and lower spring clips. Although it is easy for the user to pry it open, it is also easy for it to separate upon impact, causing the medication to spill out. Therefore, this medicine bottle also has an additional top cap that is screwed onto the bottle body by threads to protect against impacts. The user also needs to unscrew the top cap before using the medication, making the operation cumbersome. Utility Model Content The purpose of this invention is to provide a medicine bottle having the above-mentioned multi-stage dispensing cap assembly.

[0004] The medicine bottle provided by this utility model includes a bottle body, a dispensing cap, a discharging cap, and a baffle cap arranged sequentially from bottom to top. The bottle body is divided into multiple medicine slots arranged circumferentially by multiple partitions. The dispensing cap has a discharging port, and the baffle cap is installed on the dispensing cap. The baffle cap can move between a blocking position and an open position. When the baffle cap is in the blocking position, it blocks the dispensing port. When the baffle cap is in the open position, the dispensing port is open. The dispensing cap is fixedly connected to the bottle body and has multiple dispensing ports arranged circumferentially. The dispensing cap is rotatably installed on the dispensing cap, with the dispensing ports facing each other. A screw fastening structure is provided between the dispensing cap and the bottle body. After the dispensing cap rotates relative to the bottle body in a first preset rotation direction, the screw fastening structure enters the fastening state. When the screw fastening structure is in the fastening state, the vertical displacement of the dispensing cap and its rotation in the opposite direction of the first preset rotation direction are restricted.

[0005] A further embodiment is that the screw-on structure assembly includes a screw-on protrusion and a screw-on groove. The screw-on protrusion has a fastening position, and the screw-on groove has a fastening protrusion. One of the screw-on protrusion and the screw-on groove is located on the inner circumferential surface of the dispensing cap, and the other of the screw-on protrusion and the screw-on groove is located on the outer circumferential surface of the bottle. When the screw-on structure assembly is in the fastening state, the screw-on protrusion is located in the screw-on groove and the fastening position is engaged with the fastening protrusion.

[0006] As can be seen from the above solution, this utility model uses a screw-on structure to stably and reliably assemble the bottle body and the dispensing cap together, providing better anti-disassembly protection. Even if the bottle is impacted or dropped, the dispensing cap remains connected to the bottle body, preventing the medicine from falling out or becoming contaminated. Furthermore, this design eliminates the need for a separate top cap for protection; users simply need to twist the cap to dispense the medicine. This not only simplifies the product structure and reduces costs but also minimizes user steps and optimizes the user experience.

[0007] A further improvement is that the dispensing cap is also provided with a limiting protrusion, and the medicine bottle is provided with a limiting groove; when the screw fastener assembly is in the fastened state, the limiting groove restricts the limiting protrusion from rotating along the first preset rotation direction.

[0008] As can be seen above, during the process of screwing the dispensing cap onto the bottle body, the screw-on structure secures the two together to prevent the dispensing cap from retracting. This design only prevents retraction; the dispensing cap remains slightly loose, affecting the alignment between the dispensing opening and the medicine reservoir. Therefore, this invention further incorporates a limiting groove and a limiting protrusion. When the screw-on structure is engaged, the limiting groove and protrusion cooperate to prevent the dispensing cap from rotating further forward. At this point, both forward and reverse rotation of the dispensing cap are restricted, thus ensuring a stable and reliable connection between the dispensing cap and the bottle body, and guaranteeing the alignment between the dispensing opening and the medicine reservoir.

[0009] A further proposed solution is that the medicine dispensing cover includes an outer frame, ribs, and a second central seat connected sequentially from the outside to the inside, with multiple ribs distributed circumferentially along the medicine dispensing cover; the medicine dispensing opening is formed between two adjacent ribs, and when the screw fastener assembly is in the fastened state, each rib is aligned with the corresponding partition.

[0010] As can be seen from the above, in the prior art, the dispensing cap uses thin-walled openings to form dispensing ports; however, in the preferred embodiment of this utility model, the dispensing port is set to be an opening similar in size to the medicine tank. Under this premise, in the prior art, the thin wall is left with only fragile ribs separating adjacent dispensing ports, which not only makes the ribs prone to damage and breakage, but also significantly weakens the structural strength of the dispensing cap. Therefore, this utility model improves the structure of the dispensing cap by using ribs to separate the dispensing ports and connect them between the second central seat and the outer frame. The ribs themselves have good strength, and multiple ribs fix the second central seat and the outer frame as a whole. Therefore, while meeting the requirement of a large dispensing port, the overall structure of the dispensing cap has good strength and is not easily damaged. Each rib is aligned with a corresponding partition (the axial projection on the axis coincides), and a small gap is formed between the rib and the partition, which can prevent the medicine from reaching another medicine tank through a large gap, thus preventing cross-contamination.

[0011] A further proposed solution is that the baffle and the dispensing cover rotate around the same axis; the baffle is provided with a downwardly protruding rotating shaft; the dispensing cover includes a top wall and a first central seat, the first central seat protruding downward from the lower side of the top wall, the first central seat is provided with a first rotating connection hole; the second central seat is provided with a second rotating connection hole; the rotating shaft is inserted into the first rotating connection hole, and the first central seat is inserted into the second rotating connection hole.

[0012] As can be seen from the above, this design utilizes the characteristics of the rotating baffle (the baffle has a rotating shaft and the dispensing cap has a first central seat) to firmly connect the baffle, dispensing cap, and dispensing cap into one unit through a shaft-hole fit. This solves the problem of the relatively weak connection between the dispensing cap and the dispensing cap in the prior art. Furthermore, it utilizes the strength of the rib plate to resist the force when the baffle is operated, thus improving the mechanical state of the medicine bottle and making it less prone to damage.

[0013] A further embodiment is that the pivot includes at least two first spring clips arranged circumferentially at intervals, the first spring clips engaging a first center seat; and / or, the first center seat includes at least two second spring clips arranged circumferentially at intervals, the second spring clips engaging a second center seat.

[0014] As can be seen from the above, the spring-loaded design allows the rotating shaft and / or the first center seat to automatically engage after being inserted into their respective holes, quickly completing the rotational connection and axial positioning.

[0015] Another further solution is to provide at least two second protrusions spaced circumferentially on the lower side of the medicine dispensing cap; circumferentially, one second protrusion engages with the front side of a rib plate, and the other second protrusion engages with the rear side of another rib plate.

[0016] As can be seen from the above, this design utilizes the rib plate again. The circumferential limiting action of the rib plate and the second protrusion allows force to be applied to help the dispensing cap stay in its current position better.

[0017] A further proposed solution is to have two second protrusions positioned on the two sides of the medicine outlet, with each of the two second protrusions engaging with two adjacent reinforcing plates.

[0018] As can be seen above, when the dispensing cap rotates, the wall plate containing the second protrusion needs to elastically deform and float upwards before the second protrusion can cross the rib plate. Due to its proximity to the opening, the two sides of the dispensing port are more prone to deformation. This design makes it easier for the second protrusion to trigger deformation when crossing the rib plate, reducing the difficulty for the user to rotate the dispensing cap.

[0019] Another further option is to have at least one partition that can be removed.

[0020] As can be seen from the above, the amount of each drug in the user's prescription is not necessarily equal, and the size of the drugs varies. At least one partition can be removed, and after removal, it can form a larger medicine tank (composed of two medicine tanks) or even more medicine tanks (composed of multiple medicine tanks). In this way, the medicine tank has a higher degree of freedom in setting up and can meet the placement needs of different prescriptions.

[0021] Another further solution is to rotate the cover between the blocked position and the open position.

[0022] As can be seen from the above, this utility model also improves the cover from a push cover to a screw cover to optimize the user's operating feel when opening the cover.

[0023] A further proposed solution is to provide a first protrusion on the cover and a recessed structure on the dispensing cap. During the movement of the cover between the blocking position and the open position, the first protrusion and the recessed structure cooperate with each other. The recessed structure includes at least two structural groups arranged circumferentially along the rotation axis of the cover. Each structural group includes an arc groove and a first recessed point arranged sequentially along the circumferential direction. The center of the arc groove is the rotation axis of the cover.

[0024] Another further design is to make the medicine outlet fan-shaped with the rotation axis of the cover as the center.

[0025] As can be seen above, with each rotation of the cover through a structural group, the opening of the dispensing nozzle increases by one level. The first protrusion then engages with the first concave point of that structural group, allowing the cover to remain in its current position and maintain the dispensing nozzle at its current opening. Therefore, the user only needs to rotate the cover to adjust the opening size. Once the vibration generated by the engagement of the first protrusion and concave point reaches the desired setting, there is no need to support the cover when shaking the inverted medicine bottle to dispense the medicine, making operation simple and convenient. Furthermore, the advantage of designing the cover as a rotating opening is that the increase in opening size at each level is more uniform than the previous level, meaning the increase in the dispensing nozzle area is more uniform. Especially when the dispensing nozzle is fan-shaped, it is easier for the user to observe and select the desired opening size based on the required medicine volume and dispensing amount.

[0026] A further proposed solution is that the direction of rotation of the cover from the blocking position to the open position is the second preset rotation direction; the medicine outlet and the arc groove of the nearest structural group are sequentially arranged along the second preset rotation direction; when the cover is in the blocking position, the first protrusion is located in the medicine outlet.

[0027] As can be seen from the above, under this setting, the outlet itself serves as a recessed structure in the blocking position to cooperate with the first protrusion, simplifying the amount of component processing and simplifying the component construction.

[0028] A further proposed solution is that the upper side of the dispensing cap includes a high part and a low part distributed in the circumferential direction, with the low part sinking below the high part; the recessed structure and the dispensing port are in the low part, and the baffle is vertically opposite to the low part. When the baffle is in the blocking position, the high part restricts the baffle from rotating in the opposite direction of the second preset rotation direction.

[0029] As can be seen above, installing the baffle on the recessed part of the dispensing cap prevents it from being higher than the dispensing cap, resulting in a better overall appearance for the dispensing cap assembly. On the other hand, while the actions of opening and closing the cap are similar, the user experience differs. When opening, the user needs more precise control to position the baffle at the target opening degree; while when closing, the target position is always the blocking position. Ideally, the user should simply apply force to push the baffle into place without needing to think or perform precise operations. Therefore, by utilizing the higher part to block the baffle from reaching the blocking position, the baffle continues to rotate. With this design, the user doesn't need to think at all when closing the cap; they only need to apply force to rotate the baffle. The reason this effect is easy to achieve is that using a larger dispensing port instead of a single point (the first concave point) to engage with the first convex point reduces the high-precision machining requirements of a dual-fit design where the baffle and the higher part must meet, and the first convex point must accurately enter the first concave point.

[0030] Another further embodiment is that the cover includes a first wall and a second wall. The first wall extends radially along the rotation axis of the cover and includes an edge away from the rotation axis of the cover. The second wall is curved to the edge and extends axially along the rotation axis of the cover. A limiting slider is provided on the inner periphery of the second wall. A limiting groove is provided on the outer periphery of the dispensing cap. The second wall is located on the outer periphery of the dispensing cap, and the limiting slider is located in the limiting groove. The limiting groove axially restricts the limiting slider.

[0031] As can be seen from the above, under this setting, the cooperation between the limit slider and the limit groove prevents the cover from warping and deforming, and provides a guiding effect, making the cover more stable when rotating. Attached Figure Description

[0044] First embodiment of medicine bottle and dispensing cap assembly See Figure 1 The medicine bottle in this embodiment includes a bottle body 1, a dispensing cap 2, a dispensing cap 3, and a baffle cap 4. The medicine bottle 1 includes a detachable partition 19. The dispensing cap 3 and the baffle cap 4 together form the dispensing cap assembly of this utility model.

[0045] See Figure 2 The cover 4 includes a first wall 41 and a second wall 42. The first wall 41 is a wall extending along a plane perpendicular to the axis L. Further, the first wall 41 extends radially along the axis L. The first wall 41 includes a central portion 411 located at the axis L and an edge 419 away from the axis L. The second wall 42 is curvedly connected to the edge 419. The second wall 42 extends axially along the axis L and downward.

[0046] The cover 4 also includes a pivot 40, which extends axially downward along the axis L below the central portion 411. Further, the pivot 40 includes two first spring clips 49 spaced circumferentially along the axis L, located on opposite sides of the axis L. Each first spring clip 49 includes a first spring arm 491 and a first latching protrusion 492 connected to the first spring arm 491. The first spring arm 491 extends downward from below the central portion 411, and the first latching protrusion 492 protrudes radially outward from the deformed end (lower end) of the first spring arm 491. Further, the lower surface of the first latching protrusion 492 is a first trigger slope.

[0047] A downwardly protruding first protrusion 43 is provided on the lower side of the first wall 41, and the first protrusion 43 is located circumferentially around the axis L. Further, the first protrusion 43 is a circular protrusion structure, and its outer circumferential surface is a spherical cap surface or a conical surface. Further, circumferentially around the axis L, the first protrusion 43 is close to the edge of the first wall 41.

[0048] The lower side of the first wall 41 is also provided with ribs 45, which are located circumferentially around the axis L and extend in an arc shape. Two ribs 45 are distributed at different positions in the radial center of the first wall 41. The ribs 45 not only reinforce the first wall 41 but also oppose the upper surface of the medicine dispensing cover 3 below it. When the first wall 41 is subjected to downward pressure, the ribs 45 abut against the upper surface of the medicine dispensing cover 3, preventing the first wall 41 from bending and deforming. The inner circumference of the second wall 42 is provided with a limiting slider 44, which protrudes radially towards the axis L from the inner circumferential surface of the second wall 42.

[0049] See Figure 3 and Figure 4 The dispensing cap 3 includes a top wall 31 and a peripheral wall 33. The top wall 31 is a wall panel extending in a plane perpendicular to the axis L. The peripheral wall 33 is connected to the outer peripheral edge of the top wall 31 and extends downward along the axial direction of the axis L. The upper side of the top wall 31 includes a high portion 311 and a low portion 312 distributed in the circumferential direction, with the low portion 312 recessed below the high portion 311. The axial region of the top wall 31 is also located in the low portion 312. The angle traversed by the low portion 312 is smaller than the angle traversed by the high portion 311.

[0050] The lower part 312 is provided with a drug outlet 30, which penetrates both sides of the thickness of the top wall 31. The drug outlet 30 is fan-shaped with the axis L as the center. In this utility model, the fan-shaped shape of the drug outlet 30 with the axis L as the center does not limit the inner contour of the drug outlet 30 to a standard fan shape. As long as it is approximately fan-shaped, it is within the protection scope of this utility model. Further, "approximately fan-shaped" specifically means that the circumference of the drug outlet 30 is a radius line with the axis L on both the front and rear sides. The outer edge 30b and inner edge 30c of the drug outlet 30 are not required to be arc lines with the center located at the axis L. For example, in this embodiment, the outer edge 30b is an arc line with the center located at the axis L, while the inner edge 30c is an arc line with the center away from the axis L. In general, the fan-shaped design of the inner contour of the discharge port 30 mainly makes the maximum opening of the discharge port 30 larger, and the opening variable is more uniform when the opening is adjusted in the circumferential direction.

[0051] The lower part 312 is also provided with a recessed structure. In this embodiment, the recessed structure includes two structural groups 32 arranged circumferentially along the axis L. Each structural group 32 includes an arc groove 321 and a first concave point 322 arranged sequentially along the circumferential direction. The arc groove 321 and the first concave point 322 are both recessed downward on the upper surface of the lower part 312. The first concave point 322 is a circular concave position, and the center of the arc groove 321 is the axis L.

[0052] See Figure 4 The medicine outlet 30 and the two structural groups 32 are arranged sequentially along the second preset rotation direction a, and the medicine outlet 30 and the arc groove 321 of the closest structural group 32 are arranged sequentially along the second preset rotation direction a.

[0053] See Figure 3 and Figure 7 The medicine dispensing cap 3 also includes a first center seat 39, which protrudes downward from the lower side of the top wall 31. The first center seat 39 is provided with a first rotating connection hole 390, which is located at the axis L and passes through the upper and lower sides of the top wall 31 along the axial direction.

[0054] The first center seat 39 includes at least two second spring clips 399 arranged circumferentially at intervals, located on opposite sides of the axis L. Each second spring clip 399 includes a second spring arm 391 and a second latching protrusion 392 connected to the second spring arm 391. The second spring arm 391 extends downward from the first center seat 399, and the second latching protrusion 392 protrudes radially outward from the outer side of the deformed end (lower end) of the second spring arm 391. Further, the lower side of the second latching protrusion 392 forms a second triggering slope.

[0055] In addition, stepped fastening positions 398 are formed on the inner periphery of the base of the two second spring buckles 399 and on the outer periphery of the opening of the first rotating connection hole 390.

[0056] In addition, the dispensing cap 3 also includes reinforcing ribs 393, which are connected between the outer peripheral surface of the first central seat 39 and the lower surface of the top wall 31, and multiple reinforcing ribs 393 are evenly and spaced apart along the circumferential direction of the axis L.

[0057] In addition, the lower side of the top wall 31 is provided with two second protrusions 34 spaced apart along the circumference. The second protrusions 34 protrude downward from the lower surface of the top wall 31. The second protrusions 34 are circular protrusions, and their outer circumferential surfaces are set as spherical cap surfaces or conical surfaces. In the circumferential direction of the axis L, the two second protrusions 34 are respectively set on the two sides of the drug outlet 30.

[0058] In addition, the outer periphery of the peripheral wall 33 is provided with a limiting groove 331 extending circumferentially; the inner periphery of the peripheral wall 33 is provided with a second fastening protrusion 36, and a plurality of third recesses 360 are evenly arranged circumferentially on the second fastening protrusion 36; in addition, the inner periphery of the peripheral wall 33 is provided with a plurality of first snap-fit ​​ribs 35 evenly arranged circumferentially. Along the axial direction of the axis L, the second fastening protrusion 36 is closer to the top wall 31 than the first snap-fit ​​ribs 35, that is, the second fastening protrusion 36 is located above the first snap-fit ​​ribs 35.

[0059] The cover 4 is rotatably mounted on the medicine dispensing cover 3 along the axis L. The rotating shaft 40 is inserted into the first rotating connection hole 390 from top to bottom. The first spring buckle 49 can pass through the first rotating connection hole 390 after elastic deformation and contraction. When the first locking protrusion 492 reaches the stepped engagement position 398, the first spring buckle 49 returns to its original deformation and the first locking protrusion 492 engages with the first center seat 39, thereby preventing the rotating shaft 40 from coming out of the first rotating connection hole 390.

[0060] The first wall 41 and the lower part 312 are vertically opposite each other. The cover 4 can rotate around the axis L between the blocking position and the open position. The direction of rotation of the cover 4 from the blocking position to the open position is the second preset rotation direction a. When the cover 4 is in the blocking position, it blocks the medicine outlet 30. When the cover 4 is in the open position, the medicine outlet 30 is open. When the cover 4 is in the blocking position, the upper part 311 restricts the cover 4 from rotating in the opposite direction of the second preset rotation direction a. During the movement of the cover 4 between the blocking position and the open position, the first protrusion 43 cooperates with the recessed structure. In addition, the second wall 42 is located on the outer periphery of the peripheral wall 33 of the medicine outlet cover 3, and the limiting slider 44 is located in the limiting groove 331. The limiting groove 331 restricts the limiting slider 44 axially.

[0061] When the cover 4 is in the blocking position, the first protrusion 43 is located in the medicine outlet 30. When the user needs to open the cover to take medicine, push the cover 4 to rotate it in the second preset rotation direction a. The cover 4 first reaches the first process position, at which time the first protrusion 43 engages with the first arc groove 321. Then the cover 4 reaches the first opening position, at which time the first protrusion 43 engages with the first first concave point 322. If the user continues to push the cover 4, the cover 4 will first reach the second process position, at which time the first protrusion 43 engages with the second arc groove 321. Finally, the cover 4 reaches the second opening position, at which time the first protrusion 43 engages with the second first concave point 322.

[0062] After the user has taken the medicine, without considering the accuracy or force, the user can push the cover 4 and make it rotate in the opposite direction of the second preset rotation direction a until the high part 311 restricts the cover 4 from continuing to rotate. At this time, the cover 4 returns to the blocking position and the first protrusion 43 enters the medicine outlet 30.

[0063] In this configuration, the opening of the medicine outlet 30 increases by one level with each rotation of the cover 4 through the structural assembly 32, and the first protrusion 43 engages with the first concave point 322 of the structural assembly 32. The cover 4 can remain in its current position so that the medicine outlet 30 remains at its current opening. The user only needs to rotate the cover 4 to adjust the opening size. When the vibration generated by the engagement of the first protrusion 43 and the first concave point reaches the set position, there is no need to support the cover 4 when the medicine bottle is shaken to dispense the medicine, making the operation simple and convenient.

[0064] On the other hand, the advantage of setting the cover 4 as a rotating cover is that the increase in the opening degree of each level is more uniform than the increase in the opening degree of the previous level, that is, the increase in the area of ​​the medicine outlet 30 is more uniform. In particular, when the medicine outlet 30 is set as a fan shape, it is easier for users to observe and select the required opening degree according to the required drug volume and amount of medicine.

[0065] A further technical advantage is that by installing the baffle 4 in the recessed part of the dispensing cap 3, the baffle 4 does not protrude above the dispensing cap 3, resulting in a better overall appearance for the dispensing cap assembly. On the other hand, with this design, the user does not need to consider precision or force when closing the cap; they only need to apply force to rotate the baffle 4, and the higher part 311 prevents rotation when the cap is fully closed. This effect is easily achieved because the larger dispensing port 30 replaces the single-point first recess 322 to engage with the first protrusion 43, reducing the high-precision machining requirements of a dual-fit design where both the baffle 4 and the higher part 311 must abut, and the first protrusion 43 must precisely enter the first recess 322.

[0066] A further technical effect is that when the user presses the cover 4, the rib 45 abuts against the upper surface of the medicine dispensing cover 3, preventing the first wall 41 from bending and deforming. A further technical effect is that the cooperation between the limiting slider 44 and the limiting groove 331 prevents the cover 4 from warping and provides a guiding function, making the cover 4 more stable when rotating.

[0067] See also Figures 5 to 7 The medicine dispensing cover 2 includes an outer frame 21, ribs 22, and a second center seat 29 connected sequentially from the outside to the inside. Multiple ribs 22 extend radially and are evenly distributed circumferentially. A medicine dispensing opening 20 is formed between two adjacent ribs 22, extending axially.

[0068] Rib 22 is connected to the upper inner side of outer frame 21. The upper part of outer frame 21 is provided with a third spring clip 23, a third protrusion 24, and a second snap-fit ​​rib 27. The third spring clip 23 and the third protrusion 24 are both located on the upwardly extending spring arm, and are respectively located on opposite sides of axis L. The engaging protrusion of the third spring clip 23 and the third protrusion 24 both protrude radially outward. The second snap-fit ​​rib 27 is a ring-shaped protrusion with a guide slope on its upper side. The engaging protrusion of the third spring clip 23 is positioned above the position of the third protrusion 24, while the second snap-fit ​​rib 27 is positioned below the position of the third protrusion 24.

[0069] The inner circumferential surface of the outer frame 21 is provided with a snap-fit ​​protrusion 25 and a limiting protrusion 26. Both the snap-fit ​​protrusion 25 and the limiting protrusion 26 protrude from the lower inner surface of the outer frame 21, with the limiting protrusion 26 being more prominent than the snap-fit ​​protrusion 25. The snap-fit ​​protrusion 25 extends circumferentially along the axis L. The screwing direction of the dispensing cap 2 onto the bottle body 1 is a first preset rotation direction b. In the first preset rotation direction b, the front part of the snap-fit ​​protrusion 25 is provided with a recessed fastening position 251.

[0070] In addition, the second center seat 29 is provided with a second rotating connection hole 290, and a first fastening protrusion 291 is provided in the second rotating connection hole 290.

[0071] Combined Figure 8 The medicine dispensing cap 3 is rotatably mounted onto the medicine dispensing cap 2 along the axis L. The first center seat 39 is inserted into the second rotating connecting hole 290 from top to bottom. During the process, the second spring buckle 399 first contracts and deforms until the second locking protrusion 392 passes the first fastening protrusion 291. The second spring buckle 399 then returns to its original shape, and the second locking protrusion 392 engages with the first fastening protrusion 291 to prevent the first center seat 39 from falling out.

[0072] Because the second rotating connecting hole 290 needs to accommodate the second retaining protrusion 392, its upper diameter is relatively large. To strengthen the shaft-hole fit, the outer diameter of the reinforcing ribs 393 on the outer periphery of the first center seat 39 matches the upper diameter of the second rotating connecting hole 290. Furthermore, the reason for not directly increasing the root diameter of the first center seat 39 but instead using multiple spaced reinforcing ribs 393 is that if the root diameter of the first center seat 39 were increased, the thickness at that point would be too large, easily shrinking during injection molding and cooling, failing to achieve the target size. Using multiple spaced reinforcing ribs 393 solves this problem.

[0073] Furthermore, during the process of fitting the dispensing cap 3 onto the medicine dispensing cap 2 from top to bottom, the first snap-fit ​​rib 35 and the second snap-fit ​​rib 27 abut against each other, forcing the peripheral wall 33 to expand and deform until the first snap-fit ​​rib 35 passes over the second snap-fit ​​rib 27, at which point the first snap-fit ​​rib 35 and the second snap-fit ​​rib 27 are engaged, thereby preventing the dispensing cap 3 from detaching from the medicine dispensing cap 2 axially. At this time, the engaging protrusion of the third spring buckle 23 moves upward past the second engaging protrusion ring 36 and engages with it, and when the dispensing cap 3 is rotated to the correct angle, the third protrusion 24 enters the third concave point 360.

[0074] Furthermore, when the medicine dispensing cap 3 is rotated to the correct angle, one second protrusion 34 engages with the front side of a rib plate 22 for limiting, and the other second protrusion 34 engages with the rear side of another rib plate 22 for limiting. Further, in this embodiment, the two second protrusions 34 engage with two adjacent rib plates 22 respectively. The aforementioned correct angle refers to the angle between the medicine dispensing port 30 and the medicine dispensing port 20.

[0075] With the above multiple locking mechanisms, the dispensing cap 3 and the distributing cap 2 are stably and reliably connected together. When the dispensing cap 3 rotates relative to the distributing cap 2, it also receives gear feedback generated by the vibration of the second protrusion 34 and the third protrusion 24. Furthermore, the dispensing cap 3 can maintain its current angle well.

[0076] See Figures 9 to 11 The bottle body 1 has a screw-on groove 15 on the outer periphery of the upper part of the bottle mouth wall 11. The screw-on groove 15 extends circumferentially along the axis L. Furthermore, the outer peripheral surface of the bottle body 1 has a raised rib structure that extends circumferentially along the axis L, and the screw-on groove 15 is formed between adjacent rib structures.

[0077] Furthermore, the snap fastener groove 15 allows the snap fastener protrusion to enter along the first preset rotation direction b. In the first preset rotation direction b, a snap fastening protrusion 151 is provided in the snap fastener groove 15 near the extended end.

[0078] In addition, a notch is provided at the upper end of the bottle mouth wall 11. The notch opens upward and extends at a certain angle along the circumference of the axis L. This notch is the limiting groove 16 of this utility model.

[0079] The screw-on groove 15 and the screw-on protrusion 25 are the screw-on structure assembly of this utility model, which is set between the dispensing cap 2 and the bottle body 1. After the dispensing cap 2 is closed onto the bottle body 1, it is rotated relative to the bottle body 1 in the first preset rotation direction b, so that the screw-on structure assembly enters the fastening state. When the screw-on structure assembly is in the fastening state, the screw-on protrusion 25 is located in the screw-on groove 15 to prevent axial loosening, and the fastening position 251 and the fastening protrusion 151 fasten to prevent the dispensing cap 2 from reversing and loosening. Thus, the vertical displacement of the dispensing cap 2 and its rotation in the opposite direction of the first preset rotation direction b are both restricted.

[0080] Furthermore, to ensure the anti-loosening properties of the screw-on structure assembly, in this embodiment, the dispensing cap 2 is provided with two screw-on protrusions 25 spaced apart axially along the axis L. Correspondingly, the bottle body 1 is provided with two screw-on grooves 15 spaced apart axially along the axis L. Each screw-on protrusion 25 engages with a corresponding screw-on groove 15. With this axial double-locking design, the impact force of a fall is almost impossible to cause the dispensing cap 2 to deform and separate axially.

[0081] Combined Figure 11 When the snap-lock structure is engaged, the limiting groove 16 restricts the limiting protrusion 26 from continuing to rotate along the second preset rotation direction b. At this time, the forward and reverse rotation of the dispensing cap 2 is restricted, thereby ensuring a stable and reliable connection between the dispensing cap 2 and the bottle body 1, and also ensuring the alignment between the dispensing port 20 and the medicine groove 10.

[0082] In addition, when the screw fastener structure is in the fastened state, each stiffener 22 is aligned with the corresponding partition 19 (the axial projection of the partition L coincides), and a small gap is formed between the stiffener 22 and the partition 19, which can prevent the drug from reaching another drug tank 10 through a large gap, thus preventing drug cross-contamination.

[0083] During the process of screwing the dispensing cap 2 onto the bottle body 1, the snap-fit ​​structure secures the two together to prevent the dispensing cap 2 from retracting. However, this only prevents retraction; the dispensing cap 2 remains slightly loose, affecting the alignment between the dispensing opening 20 and the medicine reservoir 10. Therefore, this invention further includes a limiting groove 16 and a limiting protrusion 26. When the snap-fit ​​structure is engaged, the limiting groove 16 and the limiting protrusion 26 cooperate to prevent the dispensing cap 2 from rotating further forward. At this point, both forward and reverse rotation of the dispensing cap 2 are restricted, thus ensuring a stable and reliable connection between the dispensing cap 2 and the bottle body 1, and also guaranteeing the alignment between the dispensing opening 20 and the medicine reservoir 10.

[0084] Second embodiment of medicine bottle and dispensing cap assembly See Figure 12 In this embodiment, there are three structural groups 51. Furthermore, the structural groups 51 can be positioned closer to the outer periphery.

[0085] In other embodiments, when the cover is in the blocking position, the first protrusion engages with a first concave point.

[0086] In other embodiments, the upper side of the dispensing cap is not distinguished into a high part and a low part.

[0087] In other embodiments, the cover does not have a second wall.

[0088] In other embodiments, the dispensing port is in other shapes such as round, oval, or square.

[0089] In other embodiments, the dispensing cap has multiple dispensing openings separated by multiple ribs. Furthermore, the dispensing cap does not have a second protrusion.

[0090] In other embodiments, the partition cannot be removed.

[0091] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
