Description

Technical Field

[0001] The utility model relates to the technical field of medicine production, in particular to a medicine bottle blanking bottle cover. Background Art

[0002] At present, a relatively automated dispensing method has been realized in the process of dispensing Chinese medicine granules. This type of automated dispensing method usually involves a special bottle cap with a metering function. The cap is installed on the mouth of the medicine bottle and cooperates with corresponding automated equipment and programs to achieve automatic quantitative dispensing of medicine.

[0003] However, the amount of medicine that can be dispensed at a time with the above-mentioned bottle caps is usually fixed and cannot be changed. Therefore, there are certain defects in actual use. That is, the medicine can only be dispensed according to the designed fixed capacity each time, and the amount of medicine dispensed at a time cannot be changed. Therefore, if the proportion of the medicine is changed, the bottle cap may no longer be applicable and needs to be redesigned and replaced. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a medicine bottle dispensing bottle cover, which can meet the requirements of automatic medicine dispensing and at the same time allow the amount of medicine dispensed at a time to be adjusted within a certain range, so as to improve the applicability of the dispensing bottle cover.

[0005] The utility model solves the technical problem by adopting a technical solution: providing a medicine bottle blanking bottle cap, comprising:

[0006] A rotating body, wherein the rotating body is provided with a material removal hole;

[0007] A material discharge bottom cover, the material discharge bottom cover is arranged above the rotating body, the material discharge bottom cover has a first cavity, and a discharge hole is arranged at the bottom of the first cavity;

[0008] A follower, the follower is placed in the first cavity, the movement of the follower is controlled by the rotating body, and the follower has a metering cavity with a variable volume;

[0009] A feed top cover, the feed top cover is located above the follower and is fixedly connected to the feed bottom cover, the top of the feed top cover is used to be connected to the bottle mouth of the medicine bottle, and the bottom is provided with a feed hole;

[0010] Wherein, the rotating body can rotate relative to the material discharge bottom cover so that the metering cavity is connected with the material feed hole or the material discharge hole;

[0011] Furthermore, when the metering chamber is connected to the feed hole, the rotating body is rotated in a first clockwise direction, and the volume of the metering chamber will gradually increase until it reaches a maximum volume; when the metering chamber is connected to the discharge hole, the rotating body is rotated in a second clockwise direction, and the volume of the metering chamber will gradually decrease until it is reduced to zero.

[0012] The beneficial effect of the above technical solution is that: since the volume of the metering chamber can be changed, if the dispensing ratio changes, the amount of medicine dispensed at a single time can be adaptively changed by changing the volume of the metering chamber; compared with the existing bottle caps, the dispensing bottle cap of the utility model has better applicability and can meet the needs of different dispensing ratios.

[0018] When the rotating body rotates along the first clockwise direction to the feeding starting point, at this time, the second limiting structure rotates to the extreme position on one side relative to the first limiting structure. If the rotating body continues to rotate along the first clockwise direction, the second follower remains stationary, and the first follower continues to rotate, so that the first wall surface gradually moves away from the partition block, thereby gradually increasing the volume of the metering chamber;

[0019] When the rotating body rotates along the second clockwise direction to the material unloading starting point, at this time, the second limiting structure rotates to the extreme position on the other side relative to the first limiting structure. If the rotating body continues to rotate along the second clockwise direction, the second follower remains stationary and the first follower continues to rotate, so that the first wall surface gradually approaches the dividing block, thereby gradually reducing the volume of the metering chamber.

[0047] The present invention will be further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0048] Embodiment 1:

[0049] like Figures 1 to 5 As shown, this embodiment provides a medicine bottle feeding bottle cover, which includes a rotating body 100, a feeding bottom cover 200, a follower 300 and a feeding top cover 400.

[0050] The rotating body 100 is provided with a material removal hole 110 .

[0051] The material discharge bottom cover 200 is arranged above the rotating body 100 , and the material discharge bottom cover 200 has a first cavity 210 , and a discharge hole 220 is provided at the bottom of the first cavity 210 .

[0052] The follower 300 is disposed in the first cavity 210 , the movement of the follower 300 is controlled by the rotating body 100 , and the follower 300 has a metering cavity 3 a with a variable volume.

[0053] The feed top cover 400 is located above the follower 300 and fixedly connected to the feed bottom cover 200 . An internal thread is provided on the top of the feed top cover 400 for connecting to the bottle mouth of the medicine bottle, and a feed hole 410 is provided on the bottom of the feed top cover 400 .

[0054] The rotating body 100 can rotate relative to the material discharge bottom cover 200 so that the metering cavity 3 a is connected to the material feed hole 410 or the material discharge hole 220 .

[0055] Furthermore, when the metering chamber 3a is connected to the feed hole 410, the rotating body 100 is rotated in the first clockwise direction, and the volume of the metering chamber 3a will gradually increase until it reaches the maximum volume; when the metering chamber 3a is connected to the discharge hole 220, the rotating body 100 is rotated in the second clockwise direction, and the volume of the metering chamber 3a will gradually decrease until it is reduced to zero.

[0056] The function of the material discharge avoidance hole 110 is to avoid the discharge hole 220 when discharging medicine, so that the bottom of the discharge hole 220 is opened to ensure that the medicine can fall smoothly.

[0057] In the above technical solution, the metering chamber 3a is used to temporarily store medicines, and its volume determines the amount of medicines released at a single time, that is, when the metering chamber 3a is connected to the feed hole 410, the larger the volume of the metering chamber 3a, the more medicines will enter the metering chamber 3a from the feed hole 410, so when the metering chamber 3a is subsequently connected to the discharge hole 220, more medicines can be released; conversely, the smaller the volume of the metering chamber 3a, the less medicines will be released when the medicine is released.

[0058] Since the volume of the metering chamber 3a is adjustable when it is connected to the feed hole 410, that is, the volume of the metering chamber 3a will gradually increase when the rotating body 100 is rotated in the first clockwise direction, therefore, in the above technical solution, the amount of medicine to be dispensed at a time can be adjusted within a certain range. It can be seen that compared with the existing bottle caps, the feeding bottle cap of this embodiment has better applicability. When the proportion of medicine dispensing changes, the feed volume of the metering chamber 3a can be adjusted accordingly to change the applicability of the amount of medicine to be dispensed at a time, thereby satisfying the corresponding medicine dispensing proportion.

[0059] In a preferred implementation of this embodiment, the formation of the metering cavity 3a and the change of its volume are as follows:

[0060] See also Figure 2 The inner wall of the bottom cover 200 is provided with a first limiting structure 230, and the first limiting structure 230 is a convex block arranged on the inner wall of the bottom cover 200;

[0061] The follower 300 includes a first follower 310 and a second follower 320;

[0062] See also Figure 2 , Figure 4 and Figure 6 The first follower 310 is in linkage with the rotating body 100, and the side wall of the first follower 310 is provided with an arc-shaped notch 311, and one of the side walls of the arc-shaped notch 311 is a first wall surface 3111;

[0063] See also Figure 2 , Figure 4 and Figure 6The second follower 320 is sleeved on the periphery of the first follower 310 and is tightly against the outer wall of the first follower 310. The inner wall of the second follower 320 is provided with a partition block 321, and the outer wall is provided with a second limiting structure 322. The second limiting structure 322 is a groove arranged on the outer wall of the second follower 320; the partition block 321 is located in the arc-shaped notch 311 and is in contact with the inner side wall of the arc-shaped notch 311 (that is, the partition block 321 divides the arc-shaped notch 311 into two areas ), wherein the area between the first wall 3111 and the dividing block 321 is the metering cavity 3a, the first limiting structure 230 is clamped in the second limiting structure 322, and the arc spanned by the groove of the second limiting structure 322 is much larger than the arc spanned by the protrusion of the first limiting structure 230, therefore, the first limiting structure 230 will limit the movable range of the second limiting structure 322, thereby limiting the angular range of rotation of the second follower 320 in the first cavity 210.

[0064] In the above technical solution, since the first follower 310 is always linked with the rotating body 100 , when the rotating body 100 rotates, the first follower 310 will always rotate synchronously with the rotating body 100 .

[0065] The second follower 320 is designed to be tightly pressed against the outer wall of the first follower 310. Its purpose is to allow the second follower 320 to rotate together with the first follower 310. That is, when the first follower 310 is driven to rotate by the rotating body 100, the second follower 320 and the outer wall of the first follower 310 are tightly pressed against each other. Therefore, under the action of the friction force at the pressing point between the two, the second follower 320 will rotate together with the first follower 310, thereby allowing the metering chamber 3a to rotate to a position connected with the feed hole 410 or a position connected with the discharge hole 220.

[0066] In addition, in order to adjust the volume of the metering chamber 3a, the above technical solution deliberately adds a first limiting structure 230 and a second limiting structure 322, the purpose of which is to prevent the second follower 320 from continuing to rotate with the first follower 310 after rotating to a specific position, and then, during the subsequent rotation of the first follower 310, the distance between the first wall 3111 and the partition block 321 changes, thereby achieving the purpose of changing the volume of the metering chamber 3a.

[0067] Specific:

[0068] The points that the rotating body 100 passes through within the rotation angle range include a feeding starting point and a unloading starting point;

[0069] like Figure 7As shown, the hole wall of the feed hole 410 close to the discharge hole 220 is the feed hole front wall 411, and the hole wall away from the discharge hole 220 is the feed hole rear wall 412; Figure 7 The exploded view is when the rotating body 100 rotates along the first clockwise direction (i.e., counterclockwise direction in the figure) to the starting point of feeding. At this time, the second limiting structure 322 rotates to the extreme position on one side relative to the first limiting structure 230, and the first wall surface 3111 is aligned with the front wall 411 of the upper feeding hole 410, and at the same time, the volume of the metering cavity 3a is zero; Figure 7 On the basis of, if the rotating body 100 continues to rotate in the first clockwise direction (i.e., the counterclockwise direction in the figure), it will be blocked by the first limiting structure 230, and the second follower 320 cannot rotate with it and can only remain stationary. The first follower 310 will rotate with the rotating body 100, so the first wall 3111 will gradually move away from the partition block 321, thereby making the volume of the metering chamber 3a gradually increase, such as Figure 8 As shown, it is a display diagram showing that the volume of the metering chamber 3a increases after the first follower 310 rotates.

[0070] like Fig. 9 As shown, the discharge hole 220 has a hole wall close to the feed hole 410 as the discharge hole rear wall 222, and a hole wall away from the feed hole 410 as the discharge hole front wall 221; Fig. 9 The exploded view is when the rotating body 100 rotates along the second clockwise direction (i.e., the clockwise direction in the figure) to the starting point of material discharge. At this time, the second limiting structure 322 rotates to the extreme position on the other side relative to the first limiting structure 230, and the side wall of the partition block 321 close to the first wall surface 3111 is aligned with the front wall 221 of the discharge hole; Fig. 9 On the basis of, if the rotating body 100 continues to rotate in the second clockwise direction (i.e., the clockwise direction in the figure), it will be blocked by the first limiting structure 230, and the second follower 320 cannot rotate with it and can only remain stationary, and the first follower 310 will rotate with the rotating body 100, so the first wall 3111 will gradually move toward the direction close to the partition block 321, thereby making the volume of the metering chamber 3a gradually smaller, thereby allowing the medicine in the metering chamber 3a to be gradually discharged from the discharge hole 220, until the first wall 3111 is in contact with the partition block 321, at which time the volume of the metering chamber 3a is zero, see Fig.10 .

[0071] Based on the above technical solution, it can be known that although the first follower 310 can drive the second follower 320 to rotate together by abutting against the second follower 320, the range of rotation will be limited by the cooperation relationship between the second limiting structure 322 and the first limiting structure 230, that is, only when the second limiting structure 322 is not blocked by the first limiting structure 230, the rotation of the first follower 310 will drive the second follower 320 to rotate together, otherwise, when the first follower 310 rotates, the second follower 320 will remain motionless. Among them, when the second follower 320 rotates with the first follower 310, the role played is: to allow the metering cavity 3a to rotate to a position connected with the feed hole 410 or a position connected with the discharge hole 220. When the second follower 320 cannot rotate with the first follower 310, its role is to allow the volume of the metering chamber 3a to gradually increase or decrease, changing the feed volume of the metering chamber 3a in the process of increasing, and allowing the medicine in the metering chamber 3a to be gradually discharged from the discharge hole 220 in the process of decreasing.

[0072] Preferably, the number of the discharge holes 220 and the number of the feed holes 410 are both two, and the two discharge holes 220 and the two feed holes 410 are equally spaced around the central axis of their respective components. Correspondingly, the number of the material discharge avoidance hole 110, the first limiting structure 230, the partition block 321, the second limiting structure 322 and the arc-shaped notch 311 are also two and are equally spaced around the central axis of their respective components.

[0073] In a preferred implementation of this embodiment, in order to allow the second follower 320 to fit tightly with the outer wall of the first follower 310 to avoid slipping therebetween, a protruding structure 323 protruding toward the center of the second follower 320 is intentionally provided on the wall of the second follower 320. When the first follower 310 is placed in the second follower 320, the outer wall of the first follower 310 exerts an outward squeezing force on the protruding structure 323, causing the protruding structure 323 to undergo elastic deformation, and the elastic deformation causes the first follower 310 to be clamped in the second follower 320 by the clamp.

[0074] For further information, see Figure 2 As shown in the enlarged view in FIG, the left and right sides of the protruding structure 323 are connected to the wall of the second follower 320, and the upper and lower sides are disconnected from the wall of the second follower 320. Therefore, when the inner wall of the protruding structure 323 is subjected to an outward extrusion force, the protruding structure 323 can be displaced outward and elastically deformed based on the connection of the left and right sides and the disconnection of the upper and lower sides, and then the first follower 310 is tightly clamped in the second follower 320 by the force generated by the elastic deformation.

[0075] Preferably, there are two protruding structures 323, and the two protruding structures 323 are disposed opposite to each other on the wall of the second follower 320. The two protruding structures 323 can clamp the first follower 310 from both sides, so that the first follower 310 is clamped more firmly.

[0076] Furthermore, the inner wall of the protrusion structure 323 is undulating and protruding in a wave-like manner. Figure 2 In the enlarged view, the inner wall of the protruding structure 323 has two wavy protruding surfaces. When the first follower 310 is clamped, the two wavy protruding surfaces form two action points on the outer wall of the first follower 310, providing a better clamping effect.

[0077] In a preferred implementation of the embodiment, the first follower 310 is linked with the rotating body 100 through the following structure, specifically:

[0078] like Figure 2 As shown, a boss 120 with a hexagonal outer contour is provided in the middle of the rotating body 100, and a groove 312 matching the outer contour of the boss 120 is provided in the middle of the first follower 310. The boss 120 is inserted into the groove 312, thereby realizing the linkage between the first follower 310 and the rotating body 100.

[0079] like Figure 2 and Figure 4 As shown, in a preferred implementation manner of the present embodiment, the medicine bottle feed bottle cap further includes a guide member 500, and the guide member 500 is provided with guide slopes 510 around it for facilitating the introduction of medicine into the feed hole 410, and the guide member 500 is fixedly connected to the rotating body 100 and can move with the rotating body 100.

[0080] Preferably, a plug connector 530 matching the outer contour of the boss 120 is provided at the bottom of the flow guide 500, and the plug connector 530 is inserted into the slot 312 of the first follower 310 and fixedly connected to the boss 120 by screws. In addition, two stirring rods 520 for disturbing the medicine are provided on the opposite sides of the flow guide 500.

[0081] Therefore, when the rotating body 100 is rotated, the guide member 500 will rotate together, so the stirring rod 520 fixed on the guide member 500 can stir the medicine to prevent the medicine from being stuck above the feed hole 410 and unable to fall.

[0082] In a preferred implementation of this embodiment, an RFID tag 700 is disposed on the top of the guide member 500, and the drug name information is recorded on the RFID tag 700. By identifying the RFID tag 700, the type of medicine can be known so as to realize automatic dispensing.

[0083] In a preferred implementation manner of the present embodiment, two driving protrusions 130 are disposed opposite to each other on the outer wall of the rotating body 100 , and two positioning protrusions 420 are disposed opposite to each other on the outer wall of the feeding top cover 400 .

[0084] See also Figure 2 and Figure 4 A first magnet 140 is disposed on the top of the driving protrusion 130 , a flange is disposed around the top of the blanking bottom cover 200 , and two second magnets 240 matched with the first magnet 140 are disposed at the bottom of the flange.

[0085] When the rotating body 100 stays at the starting point of feeding, the two driving protrusions 130 correspond to the two positioning protrusions 420 respectively, and the two first magnets 140 and the two second magnets 240 also correspond to each other and are attracted to each other.

[0086] The working principle of this embodiment is as follows:

[0087] The medicine bottle is pre-filled with medicine. Before feeding the medicine, the feeding bottle cap of this embodiment is connected to the bottle mouth of the medicine bottle through the internal thread of the feeding top cover 400;

[0088] Afterwards, the medicine bottle is inverted, and the positioning protrusion 420 of the feed cover 400 is inserted into the slot of the external positioning device, and at the same time, the driving protrusion 130 of the rotating body 100 is inserted into the slot of the external driving device; that is, the feed cover 400 is kept fixed, and the rotating body 100 can be driven by the driving device to rotate clockwise or counterclockwise;

[0089] At the initial position, the two first magnets 140 of the rotating body 100 and the two second magnets 240 of the feeding bottom cover 200 overlap and are respectively adsorbed together; at this time, the rotating body 100 stays at the starting point of feeding, see Figure 7 , the first wall surface 3111 is attached to the partition block 321, the volume of the metering chamber 3a is zero, and at the same time, the first wall surface 3111 is also aligned with the front wall 411 of the feed hole, and the second limiting structure 322 is attached to one side of the first limiting structure 230;

[0090] In a single medication dispensing process, the medicine in the medicine bottle needs to first enter the metering chamber 3a to achieve the purpose of metering, and then the medicine in the metering chamber 3a is released to achieve the purpose of medication dispensing, and then the rotating body 100 and the first follower 310 and the second follower 320 are restored to the initial position, that is, one medication dispensing is completed; the specific process is as follows;

[0091] First, the driving device drives the rotating body 100 to rotate a certain angle along the first clockwise direction (i.e., along the Figure 7During this process, the second limiting structure 322 will be blocked by the first limiting structure 230, so the second follower 320 will remain stationary, and the first follower 310 will rotate counterclockwise with the rotating body 100. Figure 8 As shown, the distance between the first wall 3111 and the partition block 321 will gradually increase until the driving device stops driving the rotating body 100 to rotate. At this time, the rotating body 100 and the first follower 310 stay at the predetermined position of counterclockwise rotation, and the volume of the metering chamber 3a reaches the predetermined metering volume; during this process, the medicine in the medicine bottle will enter the metering chamber 3a through the feed hole 410 of the feed top cover 400 and fill the metering chamber 3a;

[0092] Afterwards, the driving device drives the rotating body 100 to rotate along the second clockwise direction (i.e., along the Figure 8 During this process, since the first limiting structure 230 does not block the second limiting structure 322, under the action of the protruding structure 323, the first follower 310 and the second follower 320 rotate clockwise with the rotating body 100 until the second limiting structure 322 rotates to fit with the other side of the first limiting structure 230, and the rotating body 100 arrives at the starting point of material unloading. Fig. 9 As shown, at this time, the side wall of the partition block 321 close to the first wall surface 3111 is aligned with the front wall 221 of the discharge hole, and at the same time, the metering cavity 3a is connected with the discharge hole 220, and the Chinese medicine in the metering cavity 3a begins to fall from the discharge hole 220;

[0093] Subsequently, the driving device continues to drive the rotating body 100 to rotate in the clockwise direction. During this process, the second limiting structure 322 will be blocked by the first limiting structure 230, so the second follower 320 will remain stationary, and the first follower 310 will rotate clockwise with the rotating body 100 until the first wall surface 3111 rotates to fit the partition block 321. At this time, the driving device stops driving the rotating body 100 to rotate. Fig.10 As shown, at this time, the rotating body 100 and the first follower 310 stay at the extreme position of clockwise rotation, and the volume of the metering chamber 3a becomes zero; during this process, since the volume of the metering chamber 3a will gradually shrink, the medicine in the metering chamber 3a will be gradually pushed by the first wall 3111, and then fall from the discharge hole 220 until the volume of the metering chamber 3a becomes zero;

[0094] Finally, the driving device moves in the opposite direction, driving the rotating body 100 to rotate in the counterclockwise direction. During this process, since the first limiting structure 230 will not block the second limiting structure 322, the first follower 310 and the second follower 320 will both rotate counterclockwise with the rotating body 100 until the rotating body 100, the first follower 310, and the second follower 320 return to the initial position, thereby completing a complete drug delivery process.

[0095] In the above process, when the rotating body 100 starts to rotate in the first clockwise direction from the starting point of feeding (i.e., from Figure 7 The position where the rotating body 100 stops after the rotation determines the volume of the metering chamber 3a, and then determines the amount of subsequent medicine to be dispensed. For example, the rotating body 100 starts from the starting point of the feed and rotates 30° or 45° in the first clockwise direction. The amount of medicine entering the metering chamber 3a is different, so the final amount of medicine to be dispensed is also different. Therefore, in actual use, the driving device can be used to control the rotation angle of the rotating body 100, and then control the predetermined metering volume of the metering device 3a, so that the amount of medicine dispensed at a single time can be controlled to meet the needs of different dispensing ratios.

[0096] Embodiment 2:

[0097] See also Fig.11 This embodiment also provides a medicine bottle blanking bottle cap, which is mainly different from the embodiment 1 in that:

[0098] (1) The follower 300 further includes a steel ring 330;

[0099] The wall of the second follower 320 is not provided with the protruding structure 323 of the embodiment 1, but a circle of annular grooves 324 are provided on the outer wall, and the second follower 320 is a non-closed ring on the ring, and there is a disconnected gap;

[0100] The second follower 320 is tightly pressed against the outer wall of the first follower 310 by: the steel ring 330 is clamped in the annular groove 324 of the outer wall of the second follower 320, and the steel ring 330 is used to apply a force to the second follower 320, so that the second follower 320 is tightly pressed against the outer wall of the first follower 310;

[0101] (2) The first limiting structure 230 is an arc-shaped groove arranged on the inner wall of the unloading bottom cover 200, and the second limiting structure 322 is a raised plate arranged on the outer wall of the second follower 320, and the raised plate is located in the arc-shaped groove. When the raised plate rotates to contact the end face of the arc-shaped groove, it is the extreme position within the rotation range.

[0102] That is, this embodiment adopts the method of adding a steel ring 330 on the periphery of the second follower 320 to achieve the same effect as setting a protruding structure 323 on the wall of the second follower 320 in Example 1, so that the second follower 320 is tightly pressed against the outer wall of the first follower 310, allowing the second follower 320 to rotate with the first follower 310 within the rotatable range.

[0103] The working principle of this embodiment is basically the same as that of Embodiment 1, so this article will not further describe its working principle in detail.

[0104] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
