Description

a metering bottle

technical field

The invention relates to the technical field of medicine and biological food, in particular to a manual control counting medicine bottle.

Background technique

In daily life and laboratory work, many tablets or pills are stored and stored in conventional bottles. Due to the large number of tablets in the bottle, it is necessary to open the bottle several times a day in batches. Opening the bottle cap so frequently to take medicine will cause the tablets inside the bottle to have many opportunities to contact the air for a long time, and eventually, the tablets will easily be affected by the moisture in the air and become damp and deteriorate or even fail. For some functional health foods containing flavonoids, they are easily oxidized in the air and lose their original health benefits.

Moreover, when the bottle cap is opened and the bottle body is tilted to dump the tablets, it is difficult to accurately pour out the required number of tablets. In most cases, the excess drugs are often poured out. At this time, the excess tablets can only be picked up by hand or tweezers. It is not only unsanitary, but also increases the contact time between the medicine and the air, which may affect the quality of the medicine.

Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Many specific details are set forth in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can do so without departing from the connotation of the present invention. Similar promotion, therefore, the present invention is not limited by the specific embodiments disclosed below.

Second, reference herein to "one embodiment" or "an embodiment" refers to a particular feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in various places in this specification are not all referring to the same embodiment, nor are they separate or selectively mutually exclusive from other embodiments.

Referring to Figures 1 and 2, it is the first embodiment of the present invention, which provides a metering medicine bottle. It can be seen from FIG. 1 that the metering medicine bottle includes a bottle body 100, which is the main body of a conventional medicine bottle. The upper end of the bottle body 100 has a bottle mouth 101, and the opening of the bottle mouth 101 is upward (the opening of the bottle mouth 101 is defined in the present invention. The direction is the upward direction, the same below).

The metering vial also includes a counting mechanism 200 and a top cap 300 . Among them, the counting mechanism 200 is arranged on the upper port of the bottle mouth 101 and forms a detachable connection therewith. The counting mechanism 200 is arranged at the bottle mouth 101 and can take out a limited amount of medicine during the pouring process, and can also count. Finally, the top cover 300 can not only cooperate with the counting mechanism 200 and cover the medicine outlet of the counting mechanism 200, but also can directly cooperate with the bottle mouth 101 when the counting mechanism 200 is not needed (removed). . The scenarios in which the counting mechanism 200 does not need to be used include the following: when the bottle body 100 is filled with canned tablets, when the medicine contained is in a fluid state (such as cough syrup, etc.)…

Specifically, the counting mechanism 200 includes an adapter 201 and a counting assembly 202 fixed on the upper end of the adapter 201 . The counting component 202 is a functional component for counting the number of tablets poured out, and the whole can be set in the shape of an inverted funnel, with the outlet of the “funnel” facing upwards vertically. The funnel's exits fall out one by one, making it easy to count. The counting assembly 202 is connected with the bottle body 100 through the adapter 201 (the lower end of the adapter 201 is connected with the bottle mouth 101 in a matched manner). The adapter 201 is an intermediate member capable of connecting the bottle body 100 and the top cover 300 at the same time. The top cover 300 can be connected with the outer side wall of the adapter 201 and cover the entire counting assembly 202 . In addition, after the counting mechanism 200 is removed, the top cover 300 can also be connected with the bottle mouth 101 in a cooperative manner.

In the above, "the matching connection between the adapter 201 and the bottle mouth 101, the matching connection between the adapter 201 and the top cover 300, and the matching connection between the top cover 300 and the bottle mouth 101" can all be matched by threads. The connection method is as follows:

The present invention divides the adapter 201 into an upper ring portion 201a, a middle ring portion 201b, and a lower ring portion 201c, all of which are annular structures of different sizes, and are connected in sequence from top to bottom, and their outer diameters increase sequentially. 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 has a first external thread 201b-1, and the inner side wall of the lower ring portion 201c has a first inner thread 201c- 1. In addition, the inner side wall of the lower port of the top cover 300 has a second internal thread 301 matched with the first external thread 201b-1. The thread 301 is matched to connect; the outer side wall of the bottle mouth 101 has a second outer thread 101a that is matched with the first inner thread 201c-1, and the first inner thread 201c-1 and the first inner thread 201c-1 are connected between the adapter 201 and the bottle mouth 101. The second external thread 101a cooperates for connection. Finally, if the whole counting mechanism 200 is removed, the top cover 300 can also be connected with the second outer thread 101a of the bottle mouth 101 through the second inner thread 301 .

In order to match the screw setting method of bottle caps commonly used in the market, the forward rotation (clockwise rotation) of the top cover 300 is the tightening process, and the reverse rotation (counterclockwise rotation) of the top cover 300 is the opening process. Similarly, the counting mechanism 200 rotates forward (clockwise) as its installation process, and the counting mechanism 200 rotates reversely (counterclockwise) as its removal process.

Referring to FIGS. 3-7 , it is the second embodiment of the present invention. This embodiment is different from the previous embodiment in that the counting assembly 202 includes a butt barrel 202a, and a pair of horizontally disposed inside the butt barrel 202a and attached to each other. The movable plate 202b and the blocking plate 202c. Wherein, the docking cylinder 202a is in the shape of a hollow sleeve, the lower port of which is butted with the upper port of the upper ring portion 201a, and the two are connected in an integrated structure.

Further, the outer edge of the blocking plate 202c is fixed on the inner side wall of the docking cylinder 202a, and its edge has a first sieve hole 202c-1 therethrough, preferably the first sieve hole 202c-1 is formed by the edge of the blocking plate 202c. The notch at the end is formed by being enclosed together with the inner side wall of the docking cylinder 202a, which enables the tablets from the bottle body 100 to naturally slide out from the first screen hole 202c-1 along the inner side wall of the docking cylinder 202a.

The outer edge of the movable plate 202b is just in contact with the inner side wall of the docking cylinder 202a or forms a clearance fit, and the edge of the movable plate 202b has a second screen hole 202b-1 corresponding to the first screen hole 202c-1. The movable plate 202b is attached to the upper surface of the blocking plate 202c, and can rotate horizontally with respect to the blocking plate 202c. During the rotation of the movable plate 202b, the second sieve hole 202b-1 and the first sieve hole 202c-1 can be overlapped or completely dislocated, so as to realize the connected or blocked state of the counting assembly 202.

Preferably, the structure and size of the first screen hole 202c-1 and the second screen hole 202b-1 are exactly the same, and are distributed on the same circumference at the same time. However, it should be noted that the number of the first sieve holes 202c-1 and the second sieve holes 202b-1 are the same, and there are at least one group, and when the two have multiple groups, any two adjacent second sieves on the movable plate 202b The physical space range between the holes 202b-1 can completely cover the area of a first screen hole 202c-1, so as to form a state of "complete dislocation".

Further, in order to limit the rotation range of the movable plate 202b, so that the movable plate 202b can exactly perform a complete process of "overlap" to "completely misaligned" within the rotation range, the following technical solutions can be provided:

The docking cylinder 202a has a chute 202a-1 at a height position corresponding to the movable plate 202b. The chute 202a-1 here is a through-through arc-shaped slot, which can be provided with multiple and uniformly arranged in the docking cylinder 202a, forming a week. The outer edge of the movable plate 202b has outer bumps 202b-2 corresponding to the sliding grooves 202a-1 one-to-one. Exterior of 202a. Therefore, the outer bump 202b-2 can follow the rotation of the movable plate 202b to slide in the chute 202a-1, and the arc length of the chute 202a-1 can define the rotation angle of the movable plate 202b.

The method of "arc length limits rotation angle" here is as follows:

When the movable plate 202b is rotated so that the outer bump 202b-2 abuts one end of the chute 202a-1, the second sieve hole 202b-1 and the first sieve hole 202c-1 overlap each other to form a communication; when the movable plate is rotated When the outer bump 202b-2 is pressed against the other end of the chute 202a-1 by 202b, the second screen hole 202b-1 and the first screen hole 202c-1 are completely displaced from each other to form a block.

Further, the top cover 300 is divided into a connecting part 302 and a friction part 303, wherein the connecting part 302 is used for the connection between the top cover 300 and the adapter 201 (the second internal thread 301 is located on the inner side wall of the connecting part 302) . The friction part 303 is used to contact the outer bump 202b-2 and drive the movable plate 202b to rotate horizontally. The present invention sets that the inner diameter of the friction part 303 is smaller than the inner diameter of the connecting part 302, so that the top cover 300 can be rotated out In the middle, the outer bump 202b-2 cannot hinder the second inner thread 301.

Specifically, when the top cover 300 covers the upper part of the counting component 202, the outer edge surface of the outer bump 202b-2 is attached to the inner side of the friction part 303, and the top cover 300 can connect with the outer bump through its inner side wall The frictional force between 202b-2 drives the movable plate 202b to rotate. Therefore, in the present invention, the maximum static friction force between the outer bump 202b-2 and the inner surface of the friction portion 303 is greater than the sliding friction force between the movable plate 202b and the blocking plate 202c. Preferably, a layer of anti-skid cushion material, such as a thin rubber layer, may be coated on the outer edge surface of the outer bump 202b-2.

In conclusion, 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 screw setting method of bottle caps commonly used in the market, the forward rotation (clockwise rotation) of the top cover 300 is the tightening process, and the reverse rotation (counterclockwise rotation) of the top cover 300 is the opening process. Therefore, in the present invention, it can be set that when the outer bump 202b-2 slides to the A end of the chute 202a-1, the second screen hole 202b-1 and the first screen hole 202c-1 overlap each other correspondingly to form communication, and this When the top cover 300 is in the tightening process, the medicine bottle is blocked. If the top cover 300 is reversed counterclockwise at this time, the top cover 300 can drive the movable plate 202b to rotate counterclockwise until the outer bump 202b-2 slides to the B end of the chute 202a-1. At this time, the second screen hole 202b -1 is completely displaced from the first screen hole 202c-1 to form a block, while the top cover 300 is in the process of opening. If the top cover 300 continues to be reversed, the movable plate 202b will not be able to continue to rotate due to the travel limitation of the chute 202a-1, and the top cover 300 can continue to be reversed (the external driving force is greater than that between the outer bump 202b-2 and the outer bump 202b-2). The maximum static friction force between the inner sides of the friction part 303), until the top cover 300 is completely opened and removed.

This embodiment provides the following application scenarios:

When the tablet needs to be filled into the bottle, the whole of the counting mechanism 200 is rotated counterclockwise to remove it, and then the tablet is loaded. After the canning is completed, the whole of the counting mechanism 200 is re-installed, and then the top cover 300 is fastened to the upper part of the counting mechanism 200, and the top cover 300 is rotated clockwise to tighten it.

In the above process, when the top cover 300 rotates forward clockwise, it can drive the movable plate 202b to rotate clockwise, so that the outer bump 202b-2 slides to the end A of the chute 202a-1 (the movable plate 202b cannot continue to rotate forward), At this time, the second sieve hole 202b-1 and the first sieve hole 202c-1 overlap each other correspondingly to form a connected state. If the top cover 300 continues to be rotated forward, the top cover 300 can be screwed tightly and closed, and the second screen hole 202b-1 and the first screen hole 202c-1 at this time still remain correspondingly overlapped with each other. When the bottle body 100 is tilted, the tablets in it can slide through the first sieve hole 202c-1 and the second sieve hole 202b-1 which communicate with each other in sequence, and enter the top cover 300. The top cover 300 in the present invention can be made of a transparent material (such as transparent plastic), so that the number of tablets dropped into the top cover 300 can be counted through external observation. If the number of tablets entering the top cover 300 is excessive during the process of dumping the tablets, the bottle body 100 is tilted inversely, and the tablets are dumped back without hand picking, which ensures the hygiene of the medicine.

After the number of tablets entering the top cover 300 is determined, keep the bottle body 100 tilted, turn the top cover 300 counterclockwise, and the top cover 300 can drive the movable plate 202b to rotate counterclockwise, so that the outer bump 202b-2 slides to The B end of the chute 202a-1 (the movable plate 202b cannot continue to be reversed), at this time, the second sieve hole 202b-1 and the first sieve hole 202c-1 are completely dislocated, forming a blocked state (that is, the tablets in the bottle body 100). cannot be poured out). Continue to invert the top cover 300 (the second screen hole 202b-1 and the first screen hole 202c-1 are always completely dislocated during the subsequent inversion process) until the friction part 303 is separated from the outer bump 202b-2, and finally the top cover 300 Take out with the opening facing upwards, and the inside of it just contains the above-mentioned poured tablets, and even if the top cover 300 has been opened, the second screen hole 202b-1 and the first screen hole 202c-1 are completely misaligned, forming a blocked state, so It is still possible to ensure that the tablets inside the bottle body 100 are in a sealed state and cannot be connected to the external space.

Therefore, regardless of whether the top cover 300 is in a tightly sealed state or in an open state when taking medicines, the tablets in the bottle body 100 can never communicate with the outside space, which is more conducive to the moisture-proof effect of the tablets. In addition, in the above-mentioned process, the quantitative take-out of the tablets can also be ensured, and the function of counting can be realized.

8 to 11, it is the third embodiment of the present invention. This embodiment is different from the previous embodiment in that the outer bump 202b-2 also needs to be pressed downward by the elastic member 202e, so as to realize the movable plate 202b Close fit with the blocking plate 202c.

Specifically, the outer edge of the upper end of the docking cylinder 202a has a ring of fixing rings 202d convex, and the lower side of the fixing ring 202d is concave upward to form an annular groove 202d-1 with an opening downward. At the same time, an elastic member 202e is sleeved on the outside of the docking cylinder 202a, the upper end of the elastic member 202e is fixed in the annular groove 202d-1, and the lower end abuts on the protruding outer bump 202b-2 (extending the end portion of the docking cylinder 202a) . The elastic member 202e in 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 is pressed downward by the elastic member 202e. Likewise, the maximum static friction force between the outer bump 202b-2 and the inner surface of the friction portion 303 is still greater than the sliding friction force between the movable plate 202b and the blocking plate 202c.

Further, the upper end of the docking cylinder 202a also has an inverted funnel-shaped discharge portion 202f, the inner and outer sides of the discharge portion 202f are conical curved surfaces, and the top of the discharge portion 202f has a drug outlet 202f-1. When the top cover 300 covers the upper part of the counting assembly 202 , an accommodating space M is formed between the inner side wall of the top cover 300 and the discharging part 202f, and the accommodating space M is used for temporarily accommodating the poured tablets. It should be noted that: the medicine outlet 202f-1 enables the tablets entering the discharge part 202f to slide out from the end of the discharge part 202f in sequence and singly. Therefore, it is more convenient for the user to count and count the number of tablets poured out.

Further, the top end of the medicine outlet 202f-1 never contacts the top surface of the inner side of the top cover 300, so as to ensure that the tablet sliding from the medicine outlet 202f-1 can enter the accommodating space M smoothly.
