Description

Metering medicine bottle

Technical Field

The invention relates to the technical field of medicines and biological foods, in particular to a manually-controlled counting medicine bottle.

Background

In daily life and laboratory work, a lot of tablets or pills are all contained and stored by conventional medicine bottles, and because the number of the tablets in the medicine bottles is large, the tablets need to be opened for taking in batches for many times every day. Such frequent opening of the cap for taking the medicine will result in a large contact time between the tablet inside the medicine bottle and the air, and finally the tablet is affected by the moisture in the air and is easily affected by moisture, deteriorated or even lost. For some functional health foods containing flavonoids, the foods are easily oxidized in the air and lose the original health care effect.

When the bottle cap is opened and the tablets are poured in the inclined bottle body, the tablets with the required quantity are difficult to accurately pour out, the excessive medicines are often poured out under most conditions, and the excessive tablets can be picked back into the medicine bottle only by hands or tweezers at the moment, so that the medicine bottle is not only insanitary, but also the contact time of the medicines and the air is prolonged, and the quality of the medicines is possibly influenced.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Furthermore, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 1 and 2, a first embodiment of the present invention provides a metered dose vial. As can be seen from fig. 1, the metering medicine bottle includes a body 100, which is a main body portion of a conventional medicine bottle, the body 100 has a mouth 101 at an upper end, and the mouth 101 is opened upward (the opening direction of the mouth 101 is defined as an upward direction in the present invention, the same applies below).

The metered dose vial further includes a counting mechanism 200 and a cap 300. The counting mechanism 200 is arranged at the upper port of the bottle mouth 101 and is detachably connected with the bottle mouth 101, and the counting mechanism 200 is arranged at the bottle mouth 101 and can be used for taking out the medicine in a limited quantity pouring process and counting. Finally, the cap 300 can be coupled to the counting mechanism 200 to cover the medicine outlet of the counting mechanism 200, or can be directly coupled to the bottle opening 101 when the counting mechanism 200 is not needed (removed). Scenarios where the counting mechanism 200 need not be used include the following: … … when tablets are filled into the bottle 100 and when the medicine contained is fluid (such as cough syrup, etc.)

Specifically, the counting mechanism 200 includes an adapter 201 and a counting assembly 202 fixed to an upper end of the adapter 201. The counting assembly 202 is a functional assembly for counting the number of the poured tablets, the whole counting assembly can be arranged in an inverted funnel shape, the outlet of the funnel is vertically upward, and when the bottle body 100 is inclined or inverted, the tablets can fall out from the outlet of the funnel one by one, so that the counting is convenient. The counter assembly 202 is connected to the vial 100 via the adapter 201 (the lower end of the adapter 201 is in mating connection with the vial mouth 101). The adaptor 201 is an intermediate member capable of simultaneously connecting the vial 100 and the cap 300, and the cap 300 is capable of being coupled to an outer sidewall of the adaptor 201 and covering the entire counting assembly 202. In addition, the cap 300 can also be matingly connected to the vial mouth 101 when the counter mechanism 200 is removed.

The above-mentioned "the fitting connection between the adaptor 201 and the bottle mouth 101, the fitting connection between the adaptor 201 and the cap 300, and the fitting connection between the cap 300 and the bottle mouth 101" can be connected in a screw-thread fit manner, and it is as follows:

the adapter 201 is divided into an upper ring part 201a, a middle ring part 201b and a lower ring part 201c which are all in annular structures with different sizes, and the three parts are sequentially connected from top to bottom, and the outer diameters of the three parts are sequentially increased. The upper end surface of the upper ring portion 201a is fixed and integrated with the counting assembly 202, the outer side wall of the middle ring portion 201b is provided with a first external thread 201b-1, and the inner side wall of the lower ring portion 201c is provided with a first internal thread 201 c-1. In addition, the inner side wall of the lower port of the top cap 300 is provided with a second internal thread 301 matched with the first external thread 201b-1, and the top cap 300 is connected with the adaptor 201 through the matching of the first external thread 201b-1 and the second internal thread 301; the outer side wall of the bottle mouth 101 is provided with a second external thread 101a matched with the first internal thread 201c-1, and the adaptor 201 is connected with the bottle mouth 101 through the matching of the first internal thread 201c-1 and the second external thread 101 a. Finally, when the entire counter mechanism 200 is removed, the cap 300 can be engaged with the second external thread 101a of the bottle mouth 101 through the second internal thread 301.

In order to match the cap thread arrangement commonly used in the market, the positive rotation (clockwise rotation) of the cap 300 is a screwing process, and the negative rotation (counterclockwise rotation) of the cap 300 is an opening process. Similarly, the counter mechanism 200 rotates forward (clockwise) for its installation and the counter mechanism 200 rotates backward (counterclockwise) for its removal.

Referring to fig. 3 to 7, a second embodiment of the present invention is different from the previous embodiment in that: the counting assembly 202 includes a docking barrel 202a, and a movable plate 202b and a blocking plate 202c horizontally disposed inside the docking barrel 202a and attached to each other. The docking barrel 202a is hollow and sleeve-shaped, the lower port of the docking barrel is docked with the upper port of the upper ring part 201a, and the docking barrel and the upper port are connected to form an integrated structure.

Further, the outer edge of the blocking plate 202c is fixed on the inner sidewall of the docking barrel 202a, and the edge thereof has a first screen hole 202c-1 penetrating therethrough, and preferably, the first screen hole 202c-1 is defined by a notch at the edge of the blocking plate 202c and the inner sidewall of the docking barrel 202a, so that the tablets from the bottle 100 can naturally slide out of the first screen hole 202c-1 along the inner sidewall of the docking barrel 202 a.

The outer edge of the movable plate 202b is in direct contact with or forms a clearance fit with the inner side wall of the docking barrel 202a, and the edge of the movable plate 202b is provided with a second sieve hole 202b-1 corresponding to the first sieve hole 202 c-1. The movable plate 202b is attached to the upper surface of the blocking plate 202c and can horizontally rotate with respect to the blocking plate 202 c. During the rotation of the movable plate 202b, the second sieve holes 202b-1 can be overlapped or completely dislocated with the first sieve holes 202c-1 to achieve the communication or blocking state of the counting assembly 202.

Preferably, the first screen 202c-1 and the second screen 202b-1 have the same structure and size and are distributed on the same circumference. But it should be noted that: the first holes 202c-1 and the second holes 202b-1 have the same number, and at least one group of the first holes 202c-1 and the second holes 202b-1 has a plurality of groups, and when the two groups of the first holes 202c-1 and the second holes 202b-1 are provided, the physical space range between any two adjacent second holes 202b-1 on the movable plate 202b can completely cover the area of one first hole 202c-1, so as to form a completely staggered state.

Further, in order to define the rotation range of the movable plate 202b, so that the movable plate 202b can perform exactly one complete process from "overlapping" to "completely dislocating" within the rotation range, the following technical solutions may be provided:

the butt cylinder 202a has a sliding groove 202a-1 at a position corresponding to the height of the movable plate 202b, where the sliding groove 202a-1 is an arc-shaped groove penetrating through the cylinder, and a plurality of sliding grooves may be uniformly arranged on the butt cylinder 202a to form a circle. The outer edge of the movable plate 202b has outer protrusions 202b-2 corresponding to the sliding slots 202a-1, and each outer protrusion 202b-2 passes through the corresponding sliding slot 202a-1 and extends to the outside of the docking barrel 202 a. Therefore, the outer protrusion 202b-2 can slide in the sliding groove 202a-1 following the rotation of the movable plate 202b, and the arc length of the sliding groove 202a-1 can define the rotation angle of the movable plate 202 b.

The manner of "arc length defines rotation angle" here is as follows:

when the movable plate 202b is rotated to make the outer protrusion 202b-2 abut against one end of the sliding slot 202a-1, the second screen hole 202b-1 and the first screen hole 202c-1 are correspondingly overlapped to form communication; when the movable plate 202b is rotated to make the outer protrusion 202b-2 abut against the other end of the sliding groove 202a-1, the second screen hole 202b-1 and the first screen hole 202c-1 are completely dislocated from each other to form a block.

Further, the top cover 300 is divided into a connecting portion 302 and a friction portion 303, wherein the connecting portion 302 is used for connecting the top cover 300 and the adaptor 201 (the second internal thread 301 is located on the inner side wall of the connecting portion 302). The friction portion 303 is used for contacting the outer protrusion 202b-2 and driving the movable plate 202b to rotate horizontally, and the invention is configured as follows: the inner diameter of the friction portion 303 is smaller than that of the connection portion 302, so that the second internal thread 301 is not obstructed by the outer protrusion 202b-2 during the unscrewing of the top cap 300.

Specifically, when the top cap 300 covers the upper portion of the counting assembly 202, the outer edge surface of the outer protrusion 202b-2 is attached to the inner side surface of the friction portion 303, and the top cap 300 can drive the movable plate 202b to rotate by the friction force between the inner side wall of the outer protrusion 202 b-2. Therefore, in the present invention, the maximum static friction force between the outer protrusion 202b-2 and the inner side surface of the friction part 303 is greater than the sliding friction force between the movable plate 202b and the blocking plate 202 c. Preferably, the outer surface of the outer protrusion 202b-2 is coated with a non-slip mat material, such as a thin rubber layer.

In summary, the top cover 300 can drive the movable plate 202b to rotate within a limited range, so as to control the communication or blocking state of the counting assembly 202. The specific process is as follows:

in order to match the cap thread arrangement commonly used in the market, the positive rotation (clockwise rotation) of the cap 300 is a screwing process, and the negative rotation (counterclockwise rotation) of the cap 300 is an opening process. The invention can thus set: when the outer protrusion 202b-2 slides to the end A of the sliding groove 202a-1, the second hole 202b-1 and the first hole 202c-1 are correspondingly overlapped to form communication, and the cap 300 is screwed to close the medicine bottle. If the top cover 300 is rotated counterclockwise, the top cover 300 can drive the movable plate 202B to rotate counterclockwise until the outer protrusion 202B-2 slides to the end B of the sliding slot 202a-1, and the second sieve hole 202B-1 and the first sieve hole 202c-1 are completely dislocated to form a plug, and the top cover 300 is opened. If the top cover 300 is continuously rotated reversely, the movable plate 202b cannot be continuously rotated due to the stroke limitation of the sliding groove 202a-1, and the top cover 300 can be continuously rotated reversely (the external driving external force is larger than the maximum static friction force between the outer protrusion 202b-2 and the inner side surface of the friction part 303) until the top cover 300 is completely opened and removed.

The present embodiment provides the following application scenarios:

when it is desired to fill the vial with tablets, the counting mechanism 200 is rotated counterclockwise as a whole, removed, and then filled with tablets. After filling, the whole counting mechanism 200 is re-assembled, and then the top cap 300 is covered on the upper part of the counting mechanism 200 and is screwed by rotating the top cap 300 clockwise.

In the above process, the top cap 300 can drive the movable plate 202b to rotate clockwise when rotating clockwise, so that the outer protrusion 202b-2 slides to the a end of the sliding slot 202a-1 (the movable plate 202b cannot rotate clockwise), and at this time, the second sieve hole 202b-1 and the first sieve hole 202c-1 are correspondingly overlapped with each other to form a communicating state. If the cap 300 is rotated forward, the cap 300 can be tightly screwed, and the second screen hole 202b-1 and the first screen hole 202c-1 are still overlapped with each other. When the bottle body 100 is tilted, tablets inside thereof can sequentially slide through the first and second sieve holes 202c-1 and 202b-1 communicating with each other, and enter the cap 300. The cap 300 of the present invention may be made of a transparent material (e.g., transparent plastic) so that the number of tablets falling into the cap 300 can be counted by external observation. If the number of tablets entering the top cover 300 is excessive during the tablet pouring process, the bottle body 100 is reversely inclined to pour the tablets back without being picked up by hands, so that the sanitation of taking the tablets is guaranteed.

After the number of tablets entering the cap 300 is determined, the bottle body 100 is kept inclined, the cap 300 is rotated counterclockwise, and the cap 300 can drive the movable plate 202B to rotate counterclockwise, so that the outer protrusion 202B-2 slides to the end B of the chute 202a-1 (the movable plate 202B cannot rotate backward), and at this time, the second sieve hole 202B-1 and the first sieve hole 202c-1 are completely dislocated to form a blocking state (i.e., the tablets in the bottle body 100 cannot be poured out). The cap 300 is continuously turned over (the second sieve hole 202b-1 and the first sieve hole 202c-1 are always completely dislocated in the subsequent turning process), until the friction part 303 is separated from the outer convex block 202b-2, and finally the cap 300 is taken out with the opening facing upwards, and the poured tablets are just contained in the cap 300, and even if the cap 300 is opened, the tablet inside the bottle body 100 can be ensured to be in a sealed state and cannot be communicated with the external space because the second sieve hole 202b-1 and the first sieve hole 202c-1 are completely dislocated to form a blocking state.

Therefore, no matter the cap 300 is in a sealed state of being screwed or in an opened state when taking medicine, the tablet in the bottle body 100 cannot be communicated with the external space all the time, which can be more favorable for the moisture-proof effect of the tablet. In addition, in the process, the quantitative taking-out of the tablets can be ensured, and the counting function is realized.

Referring to fig. 8 to 11, a third embodiment of the present invention is different from the previous embodiment in that: the outer protrusion 202b-2 is also pressed downward by the elastic member 202e, so as to achieve the close fit between the movable plate 202b and the blocking plate 202 c.

Specifically, the butt-joint cylinder 202a has a convex fixing ring 202d at the outer edge of the upper end, and the lower side of the fixing ring 202d is concave to form an annular groove 202d-1 with a downward opening. Meanwhile, the elastic member 202e is fitted over the docking cylinder 202a, and the upper end of the elastic member 202e is fixed in the annular groove 202d-1 and the lower end thereof abuts against the protruding outer protrusion 202b-2 (the end portion protruding from the docking cylinder 202 a). The elastic member 202e of the present invention can be a spring, and the movable plate 202b can be attached to the upper surface of the blocking plate 202c when the outer protrusion 202b-2 presses the elastic member 202e downward. Similarly, the maximum static friction force between the outer convex block 202b-2 and the inner side surface of the friction part 303 is still larger than the sliding friction force between the movable plate 202b and the blocking plate 202 c.

Further, the upper end of the butt-joint cylinder 202a is also provided with a discharge part 202f in an inverted funnel shape, the inner side surface and the outer side surface of the discharge part 202f are both conical curved surfaces, and the top of the discharge part 202f is provided with a medicine outlet 202 f-1. When the top cap 300 covers the upper portion of the counting assembly 202, an accommodating space M is formed between the inner sidewall of the top cap 300 and the discharge portion 202f, and the accommodating space M is used for temporarily accommodating the poured tablets. It should be noted that: the outlet 202f-1 allows the tablets entering the outlet 202f to be sequentially and singly slid out from the end thereof, thereby facilitating the counting of the user and counting the number of tablets to be discharged.

Further, the top end of the medicine outlet 202f-1 can not contact the top surface of the inner side of the top cover 300 all the time, so as to ensure that the tablets sliding down from the medicine outlet 202f-1 can smoothly enter the accommodating space M.
