Description

Technical Field

[0001] The utility model relates to the technical field of double-compartment bottles, in particular to a double-compartment bottle structure. Background Art

[0002] The dual-compartment bottle market is a complex and important field. Dual-compartment bottle technology creates two separate compartments within a single container, storing different ingredients in each compartment, which are then mixed when used. This design avoids problems such as moisture and deformation of solid pharmaceuticals, while ensuring the freshness and effectiveness of the drugs. Traditional dual-compartment mixing bottles require considerable force to open the inner compartment, but the new technology, through the setting of structures such as the screw cap and the inner compartment, allows users to easily open the inner compartment by rotating the screw cap, achieving mixing of the two ingredients. The operation is simple and labor-saving. Dual-compartment bottle technology is particularly suitable for drugs that need to be mixed, such as lyophilized preparations and diluents.

[0003] This design reduces the number of containers required for traditional drug administration, simplifies the drug administration process, and allows both medical staff and patients to easily reconstitute and administer the drug. For sensitive biomacromolecule drugs, the dual-compartment bottle technology helps maintain the stability of the drug formulation during its effective period by mixing or reconstituted the two contents before administration. Due to its high dosage accuracy, the dual-compartment bottle technology is safer and more convenient for patients, especially when using high-concentration drugs. The dual-compartment bottle technology can reduce the impact of mutual reactions between ingredients on product activity, extend the shelf life of the product, and reduce losses from unsold product series. The dual-compartment bottle technology is not only widely used in the pharmaceutical industry, but also in medical devices, cosmetic containers and other fields, providing a packaging solution with a simple structure, easy use, small capacity and high freshness preservation.

[0019] The technical solution of the present invention will be further described below through specific embodiments in combination with the accompanying drawings. The described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example 1: Reference Figures 1 to 3 , a double-chamber bottle structure, which includes a bottle body 3, which is cylindrical as a whole. One end of the bottle body 3 is provided with a connecting thread for connecting the cover 2. A cover 2 is connected above the bottle body 3, and the cover 2 is also provided with an internal thread. The cover 2 not only closes the bottle body, but also controls the outflow of liquid. The cover 2 is also cylindrical. A pinch tube 21 is provided on the cover 2. The pinch tube 21 is a flexible part. The middle part of the pinch tube 21 is provided with several protrusions so that it will not slip during operation. The material of the pinch tube 21 can be selected according to the actual liquid demand. A dripping port 22 is connected above this pinch tube. This design allows the liquid in the bottle to be controlled and dripped out through the pinching tube 21 and the dripping port 22, which is suitable for liquids that need to be measured or slowly released.

[0021] It should be noted that a dropper cover 1 is connected to the top of the cover 2. The bottom of the dropper cover 1 is designed with an anti-slip member 11. The anti-slip member 11 is a circle with textures. This anti-slip member 11 with textures allows the operator to have greater friction between the finger and the dropper cover 1 when opening this structure, making it easier to open and preventing it from slipping or shifting during use. The bottle body 3 can be selected from the most suitable material according to the properties of the liquid to be stored. This allows the bottle body 3 to adapt to various liquids, including corrosive chemicals. If the liquid is acidic or alkaline, acid- and alkali-resistant plastic or glass can be selected; if the liquid is an organic solvent, special plastic or stainless steel that can resist solvent erosion can be selected.

[0022] It should be noted that the bottom of the bottle body 3 is designed to be circular. The circular shape allows the liquid to be evenly distributed and facilitates the placement and transportation of the bottle. At the bottom of the bottle body 3, there is a pressing block 4 connected. The design of this pressing block 4 allows it to be snapped into the bottle bottom 3 to form a stable connection. The pressing block 4 can also be easily removed when necessary for easy cleaning and maintenance. An inner bottle 5 is connected above the pressing block 4. This double-layer design allows the double-compartment bottle structure to store two different substances at the same time, or to divide a substance into two independent parts for easy control and use. The shape of the inner bottle 5 can be adjusted as needed to adapt to different storage needs.

[0023] It's also important to note that before using this dual-chamber bottle structure, the inner bottle 5 must first be filled with the desired substance. The inner bottle 5 is screwed onto the top of the pressing block 4. This threaded connection ensures that the inner bottle 5 is securely mounted on the pressing block 4. After filling, the inner bottle 5 and the pressing block 4 are pressed into the bottle body 3. The grooves designed inside the bottle body 3 mate with the pressing block 4, locking the pressing block in place and securing the inner bottle 5 in place. Next, the cover 2 is unscrewed, and another substance is filled through the top of the bottle body 3. The cover 2 is then tightened again. Finally, the dropper cap 1 is screwed on, and the next step is ready. To mix the substance in the inner bottle 5 with that in the bottle body 3, the pressing member 6 is pushed to puncture the protective layer 52 at the mouth of the inner bottle 5. This action releases the substance inside the inner bottle 5 and allows it to mix with the substance in the bottle body 3. The design of the protective layer 52 both protects the purity of the substance inside the inner bottle 5 and conveniently allows for mixing when needed. Once the protective layer 52 is punctured, the substance in the inner bottle 5 can freely communicate with the substance in the bottle body 3, thereby achieving the dual storage and mixing functions of the dual-compartment bottle structure. After completing the above steps, the dropper cap 1 is unscrewed, and the dual-compartment bottle structure is put into use. The mixing ratio and timing of the two substances can be controlled as needed.

[0024] The specific working steps of this embodiment are as follows: This structure is mainly composed of a cylindrical bottle body 3, one end of which is provided with a connecting thread for connecting to the cover 2. The cover 2 is internally threaded, which not only seals the bottle body but also controls the outflow of liquid. The cover 2 has a flexible pinch tube 21 with a ridge in the middle to prevent slipping. The material can be selected according to the liquid required. The top of the pinch tube is connected to a dripping spout 22, which facilitates the control and dripping of liquid, suitable for metering or slow release of liquid. There is also a dropper cap 1 above the cover 2, with a textured anti-slip member 11 at the bottom to increase friction, improve opening stability and safety, and prevent slipping. The material of the bottle body 3 can be selected according to the properties of the stored liquid and is suitable for various liquids, including corrosive chemicals. The bottom of the bottle body 3 is designed to be rounded to facilitate even distribution and transportation of the liquid. It is connected to a pressure block 4 to form a stable connection and facilitate disassembly for cleaning and maintenance. The inner bottle 5 is connected to the top of the pressing block 4. The double-layer design can store two substances at the same time or divide one substance into two parts. The shape of the inner bottle 5 can be adjusted according to needs. When in use, fill the inner bottle 5 first, screw the filled inner bottle 5 into the thread above the pressing block, and after the vial is filled, press the assembled inner bottle 5 into the bottle body 3. The bottle body 3 is provided with a groove to clamp the pressing block, and then unscrew the cover 2, fill the material from the upper mouth of the bottle body, and then screw on the dropper cap 1. By pushing the pressing piece 6 to pierce the protective layer 52, the inner bottle is mixed with the liquid in the bottle body, and the dropper cap 1 is unscrewed for use.

[0025] Example 2: Reference Figures 1 to 3The main structure of this embodiment is similar to that of Example 1, but the shape of the pressure piece 6 has been extended. The bottle body 3 is cylindrical, ensuring structural strength while also being easy to hold and place. One end of the bottle body 3 features a connecting thread. This detailed design allows the bottle body 3 to securely connect to the cover 2. The cover 2 is also cylindrical and features internal threads that mate with the external threads of the bottle body 3, ensuring a tight fit. The cover 2 is not limited to sealing the bottle body; it also incorporates a flexible pinch tube 21. The center of the pinch tube 21 features several protrusions, increasing stability during operation and preventing slippage. The material of the pinch tube 21 can be selected based on the properties of the stored liquid, adapting to varying chemical and physical states, ensuring safe and reliable use. A drip nozzle 22 is connected to the top of the pinch tube 21. This design allows the liquid in the bottle to be controlled and dripped out through the pinch tube 21 and drip nozzle 22.

[0026] It should be noted that a dropper cover 1 is also connected to the top of the cover 2, and the bottom of the dropper cover 1 is designed with an anti-slip part 11. This detailed design increases the friction between the operator's fingers and the dropper cover 1 when opening this structure, making it easier to open, while improving the stability and safety during use, and preventing it from slipping or shifting during use. The bottom of the bottle body 3 is designed to be circular, so that the liquid is evenly distributed, which is convenient for bottle placement and transportation. At the bottom of the bottle body 3, a pressing block 4 is connected. The design of the pressing block 4 allows it to be stuck into the bottle bottom 3 to form a stable connection. The pressing block 4 can also be easily removed when needed for easy cleaning and maintenance. An inner bottle 5 is connected above the pressing block 4. This double-layer design allows the double-compartment bottle structure to store two different substances at the same time, or to divide a substance into two independent parts for easy control and use. The shape of the inner bottle 5 can be adjusted as needed to adapt to different storage needs.

[0027] It should be noted that the hook-shaped positioning member 7 is used to fix the pressing block 4 and the bottle body 3. The pressing block 4 and the pressing member 6 are fixed by a hook-shaped positioning member 7. This fixing method is both stable and easy to disassemble, convenient for maintenance and cleaning. At the same time, a pressing block ring 42 is also provided inside the pressing block 4. The pressing block ring 42 itself is a part of the pressing block 4 and is located at the upper end of the pressing block 4. This pressing block ring 42 can be stuck into the hook-shaped positioning member 7. The hook-shaped positioning member 7 is a wide strip on one side and a shorter strip on the other side. The groove formed by the two strips locks the pressing block ring 42. The groove formed by the two strips can just clamp the pressing block ring 42, ensuring that the fixing of the pressing block 4 on the bottle body 3 is more secure. At the same time, the sealing performance of the liquid inside the pressing block ring 42 is good, preventing the liquid from leaking from the inside of the pressing block ring 42.

[0028] It should be noted that a pressing block protrusion 41 is designed at the bottom of the pressing block 4. The pressing block protrusion is a hollow or elastic protrusion. This protrusion can be embedded in the bottle body groove 31 at the bottom of the bottle body 3. This design makes the connection between the bottle body and the pressing block tighter, ensuring the sealing and stability of the overall structure. The bottle body 3 and the pressing block 4 together form a first silo 32, which can store substances such as liquids or powders, and the inner bottle 5 is provided with a second silo 51 inside. This second silo can also store different substances. The entire double-bin bottle structure can store two different substances at the same time without interfering with each other. The bottle mouth of the inner bottle 5 is covered with a protective layer 52. This protective layer can protect the bottle mouth from contamination and ensure the purity and safety of the substances inside the inner bottle.

[0029] It should be noted that the interior of the pressure block 4 is designed with a pressure piece 6 and a pressure block notch 43. One end of the pressure piece 6 is a curved pressure portion 61, which better conforms to the shape of the human hand, making it more convenient and labor-saving to use. While the curved pressure portion 61 is designed to control the liquid flow rate, a hook-shaped positioning member 7 is designed inside the pressure piece to secure the pressure piece 4 to the bottle body 3. The other side of the pressure piece 6 is designed with a stab hole 62. This stab hole 62 is spiral-shaped and has a sharp bevel at the top. When pressed, it can directly penetrate into the inner bottle 5. At the same time, because the stab holes 5 are independent thorns, liquid can flow out through the hollow area. This stab hole interacts with the inner bottle 5 to achieve liquid control and distribution. This design allows liquid to be guided out of the inner bottle 5 while maintaining its purity and safety. The stab hole 62 also prevents liquid leakage. The bottle body 3, pressure block 4, inner bottle 5, and pressure piece 6, together, effectively control and distribute the liquid.

[0030] The specific working steps of this embodiment: The double-bin bottle structure in Example 2 has a main structure similar to that of Example 1, and the shape of the pressing piece 6 has been adjusted. The bottle body 3 is cylindrical, with a connecting thread at one end connected to the sleeve cover 2, and the sleeve cover 2 is provided with an internal thread matching the bottle body 3. There is a flexible pinch tube 21 on the sleeve cover 2, with a protrusion in the middle, the material is variable, and there is a dropper 22 on the top. The bottom of the dropper cover 1 has a textured anti-slip part 11. The bottom of the bottle body 3 is circular, connected to a detachable pressing block 4, and there is an inner bottle 5 on the top, forming a double-layer storage. The hook-shaped positioning piece 7 fixes the pressing block 4 and the bottle body 3, and there is a pressing block ring 42 in the pressing block 4. The pressing block protrusion 41 at the bottom of the pressing block 4 is embedded in the groove 31 at the bottom of the bottle body 3. The bottle body 3 and the pressing block 4 form a first material bin 32, and a second material bin 51 is provided in the inner bottle 5. The mouth of the inner bottle 5 has a protective layer 52. The pressing piece 6 and the pressing piece notch 43 inside the pressing piece 4 are designed with a curved pressing portion 61 on one end and a puncture 62 on the other side. Before using the double-chamber bottle structure, the inner bottle 5 must be filled and screwed onto the pressing piece 4. Then, the inner bottle 5 and the pressing piece 4 must be pressed together into the bottle body 3. The pressing piece 4 is clamped in the groove inside the bottle body 3 to fix the inner bottle 5. Unscrew the cover 2, fill another substance through the upper opening of the bottle body 3, tighten the cover 2, and finally screw on the dropper cap 1. Push the pressing piece 6 to puncture the protective layer 52, so that the substance in the inner bottle 5 is mixed with the substance in the bottle body 3. The protective layer 52 not only protects the purity of the substance in the inner bottle 5, but also facilitates mixing. After puncture, the substances in the inner bottle 5 and the bottle body 3 can be mixed freely, realizing the dual storage and mixing functions of the double-chamber bottle. After unscrewing the dropper cap 1, the double-chamber bottle structure can be used, allowing the control of the mixing ratio and timing of the two substances.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
