Description

A double-layer bottle cap Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a bottle cap that provides an accurate number of pills. Background Technology

[0002] When administering different doses, multiple tablets need to be poured out of the medicine bottle at once, and there has always been a desire for a product that can accurately measure the amount of medicine.

[0003] Furthermore, microtablets refer to tiny tablets with a diameter between 1 and 4 mm. Compared to traditional tablets, microtablets offer advantages such as flexible dosage and ease of swallowing, making them suitable for pediatric patients, elderly patients, and those requiring special formulations. Due to their flexible dosage, the number of microtablets can be adjusted for personalized dosing. Children, in particular, require dosage adjustments based on weight due to significant differences in age; this can be achieved by flexibly increasing or decreasing the number of microtablets. However, because microtablets are very small, it is easy to overdose when the bottle is open and poured. Dividing the medication for each dose is not only inefficient but also prone to secondary contamination.

[0004] Although CN208393999U adopts a top and bottom cover design, the tablets are still poured out through the dispensing hole, which cannot guarantee that only one tablet passes through the dispensing hole at a time. Its three dispensing holes can only dispense an approximate number of tablets (large quantity, small quantity), requiring careful operation. Even so, it is still difficult to dispense tablets accurately, especially small micro-tablets. Summary of the Invention

[0005] To address the aforementioned issues, a double-layered dispensing bottle is provided, capable of dispensing an accurate quantity of tablets, especially micro-tablets.

[0006] This utility model provides a double-layer bottle cap, comprising an upper bottle cap and a lower bottle cap; the upper bottle cap has a recessed dispensing hole, which is closed around its perimeter and open at the bottom; the lower bottle cap has a through hole, and other positions can be provided with an array of recessed medicine-holding slots; the upper bottle cap is rotatably connected to the lower bottle cap, and the distance between the two allows one tablet to pass through freely. When the upper bottle cap is rotated, the dispensing hole is either closed, or partially or completely exposed to the array of medicine-holding slots on the lower bottle cap, and the dispensing hole is not opposite to the through hole on the lower bottle cap.

[0007] In one embodiment of the double-layer bottle cap of this utility model, the array of medicine-holding troughs is one or more.

[0008] The medicine-holding trough array described in this utility model refers to multiple medicine-holding troughs clustered together. Each medicine-holding trough is suitable for holding one tablet, and its shape can be concave and bowl-shaped or barrel-shaped, as long as it is suitable for holding a specific tablet.

[0009] In one embodiment of the double-layered bottle cap of this utility model, the upper bottle cap is transparent and visible. The transparent upper bottle cap allows for a clear view of the number of tablets in the medicine container.

[0010] In one embodiment of the double-layer bottle cap of this utility model, the lower bottle cap has a scale marking indicating the number of tablets that can be removed when the upper bottle cap is rotated to a specific position relative to the lower bottle cap.

[0011] In one embodiment of the double-layer bottle cap of this utility model, the medicine outlet is fan-shaped, the lower bottle cap is annular, and the middle is a circular through hole. Two medicine holding slots are arranged opposite each other on the left and right sides of the through hole. The radius of the fan-shaped medicine outlet is equal to the radius of the lower bottle cap annularity and is located in the part of the lower bottle cap annularity.

[0012] In one embodiment of the double-layer bottle cap of this utility model, the inner side of the lower bottle cap is provided with threads, and the outer ring of the bottom of the inner side is provided with a circular guide groove. The lower side of the upper bottle cap is provided with a circular guide rail, and the guide rail is installed in the guide groove. The rotational connection between the upper and lower bottle caps can also be achieved by other methods well known in the art.

[0013] The double-layer bottle cap of this invention can be fitted to the bottle body through the threads on the inner side of the lower bottle cap.

[0014] In one embodiment of the double-layer bottle cap of this utility model, the number of medicine-holding slots in one medicine-holding slot array is odd, and the number of medicine-holding slots in the other medicine-holding slot array is even, with a maximum of two medicine-holding slots distributed radially along the fan-shaped medicine dispensing hole. In a specific embodiment of the double-layer bottle cap of this utility model, the medicine-holding slots in one medicine-holding slot array are arranged as follows along the radial direction of the fan-shaped medicine dispensing hole: 1, 2, 2, 2, 2, 2; and the medicine-holding slots in the other medicine-holding slot array are arranged as follows: 2, 2, 2, 2, 2, 2. Correspondingly, 1, 2, 3, 4, 5, 6, 7, 8, and 10 tablets can be directly dispensed at once. A suitable medicine-holding slot array arrangement can be designed according to the size of the tablets and the required number of tablets.

[0015] In one embodiment of the double-layer bottle cap of this utility model, the bottle cap is used for medicine bottles containing micro-flake drugs with a diameter of 3-5 mm and a height of 2-3 mm.

[0016] In another embodiment of the double-layer bottle cap of this utility model, the bottle cap is used for medicine bottles containing micro-flake drugs with a diameter of 1-4 mm and a height of 2-3 mm.

[0017] When using the double-layered bottle cap of this invention, when the upper bottle cap is sealed, invert the bottle and gently shake it left and right. The tablets will enter between the lower and upper bottle caps through the through hole in the middle of the lower bottle cap. Invert the bottle so that the tablets enter the medicine storage slot. Shake the bottle left and right again so that the tablets that do not fall into the medicine storage slot fall back into the bottle through the through hole. At this time, rotate the upper bottle cap as needed to expose the required medicine storage slot array at the dispensing hole to obtain the required number of tablets. Rotate the upper bottle cap back to its sealed state.

[0018] The double-layered cap of this invention can accurately dispense the required dose of tablets, effectively preventing secondary contamination, saving time, and providing hygiene and convenience. Attached Figure Description

[0023] This invention relates to a double-layer bottle cap, as described in the accompanying drawings. The double-layer bottle cap comprises an upper cap 1 and a lower cap 2. The upper cap 1 is made of transparent material, allowing visibility of the medicine-holding compartment 5. It has a recessed fan-shaped medicine outlet 3, which is closed around its perimeter but open at the bottom. The lower cap 2 is annular, with a through hole 4 in the center. Two medicine-holding compartment arrays 2-1 and 2-2 are distributed opposite each other around the through hole 4 (see Figures 1 and 2). In medicine-holding compartment array 2-1, the number of medicine-holding compartments 5 is odd, with 1, 2, 2, 2, 2 arranged along the radius of the fan-shaped medicine outlet. In medicine-holding compartment array 2-2, the number of medicine-holding compartments 5 is even, with 2, 2, 2, 2, 2 arranged along the radius of the fan-shaped medicine outlet (see Figure 2). Accordingly, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 tablets can be dispensed directly at once. The upper cap 1 is rotatably connected to the lower cap 2, with the distance between them allowing one tablet to pass freely. When not in use, the dispensing hole 3 of the upper cap 1 does not cover the medicine storage array and is in a sealed state. When in use, the medicine bottle is inverted and gently shaken from side to side. The tablets enter between the lower cap 2 and the upper cap 1 through the through hole 4 of the lower cap 2. The medicine bottle is then inverted so that the tablets enter the medicine storage array 5. The medicine bottle is shaken from side to side again so that any tablets that do not fall into the medicine storage array 5 fall back into the medicine bottle through the through hole. At this time, the upper cap 1 is rotated so that the required medicine storage array is exposed at the dispensing hole 3, and the required number of tablets are obtained. Finally, the upper cap 1 is rotated back to its sealed state.

[0024] The lower cap 2 can be threaded inside to engage with the bottle body, as shown in Figure 3.
