Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical storage devices, specifically to a powdered pharmaceutical storage tank. Background Technology

[0002] In the pharmaceutical field, powdered medicines are widely used due to their ease of storage, transportation, and patient administration. However, existing powdered medicine storage containers present several problems. Firstly, traditional storage containers have poor sealing, allowing moisture from the air to easily enter, causing the powdered medicines to become damp and clump, thus affecting their quality and efficacy. Secondly, after multiple dispensings, the frequent exchange of air between the container and the outside environment further exacerbates the risk of moisture absorption and deterioration. Furthermore, while some existing storage devices incorporate desiccants, these are typically placed directly inside the container, easily mixing with the medicine and affecting both accessibility and potential contamination. Therefore, effectively addressing the problem of moisture absorption and deterioration of powdered medicines during storage, while ensuring both convenience and safety in dispensing, is a pressing technical challenge.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0016] Optionally, a second step structure is also provided on the medicine dispensing port. The second step structure is located above the first step structure, and the diameter of the lower end of the second step structure is larger than the diameter of its upper end.

[0017] The diameter of the upper end of the first step structure is larger than the diameter of the upper end of the second step structure.

[0018] Optionally, a support rod is connected to the top inner side of the sealing cover. The support rod is set vertically downward, and the bottom of the support rod is detachably connected to the receiving cavity.

[0019] Optionally, a sealing plug is movably provided at the bottom of the sealing cap, the sealing plug being configured to isolate and protect the desiccant inside the sealing cap when the medicine is taken out.

[0020] Optionally, an isolation filter is provided on the opening of the medicine dispensing port. The isolation filter is configured to allow gas to pass through while preventing particulate powder from passing through.

[0021] Compared with the prior art, the embodiments of this utility model have the following advantages and beneficial effects:

[0022] 1. The present invention provides a powder medicine storage container. The sealing cap is tightly connected to the dispensing port through its detachable structure, forming a good sealing effect. Then, an independent receiving cavity is set inside the sealing cap for placing desiccant. Several vent holes are provided on the cavity wall. These vent holes allow water vapor inside the container to enter the receiving cavity and be absorbed by the desiccant, thereby reducing the humidity inside the container. The receiving cavity fits tightly with the inner wall of the sealing cap to form a relatively independent drying area. The receiving cavity is located outside the dispensing port and there is a gap between the receiving cavity and the dispensing port to avoid direct contact between the desiccant and the dispensing port, thereby ensuring the convenience and safety of dispensing medicine.

[0023] 2. In this embodiment of the invention, the receiving cavity is fixed to the top of the sealing cap, with its bottom surface directly facing the upper opening of the dispensing port. When the sealing cap is closed, the bottom surface of the receiving cavity fits tightly with the upper opening of the dispensing port, but a certain gap is maintained between them to prevent direct contact between the desiccant and the medicine. The vertical projection of the upper opening of the dispensing port falls completely into the bottom surface of the receiving cavity, ensuring that air and water vapor can enter the receiving cavity to the maximum extent through the vent. The receiving cavity can also absorb moisture from the air through the vents on the side, while the gap between the receiving cavity and the sealing cap ensures air circulation, further improving the adsorption efficiency of the desiccant.

[0024] 3. In this embodiment of the utility model, the upper and lower parts of the can body are connected by a detachable sealing connection to ensure good sealing of the can body during use. The medicine dispensing port is located above the upper part of the can body. The smaller opening diameter makes it easy for users to accurately dispense medicine, while reducing the amount of air entering the can. The detachable design of the upper and lower parts allows for a larger opening diameter for efficient medicine filling.

[0025] 4. In this embodiment of the utility model, by setting a first step structure, the sealing cap will fit tightly with the lower end of the first step structure during installation. Through the transition of the step structure, the sealing performance between the sealing cap and the medicine dispensing port is ensured. The upper end of the first step structure has a smaller diameter, which can further reduce the amount of air entering the can when dispensing medicine.

[0026] In general, the powdered medicine storage container provided by the embodiments of this utility model improves the storage period of powdered medicines by providing a receiving cavity for containing desiccant inside the sealing cover and making the sealing cover and the medicine dispensing port detachable.

[0038] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0039] Example

[0040] Example 1: As Figure 1 and Figure 4 As shown, this utility model embodiment provides a powdered medicine storage container, including a container body 1 and a sealing cap 3. The container body 1 is used to store powdered medicine, and its top is provided with a dispensing port 2 for easy access by the user. It should be noted that the container body 1 can be made of a material with good sealing properties, such as plastic or glass, to prevent the external environment from directly affecting the medicine. The sealing cap 3 is detachably connected to the dispensing port 2 to seal the dispensing port 2 and prevent moisture in the air from entering the container, thereby reducing the risk of the medicine becoming damp. The sealing cap 3 can be tightly connected to the dispensing port 2 by threads, snaps, or other detachable structures, or a sealing ring can be provided to enhance the sealing performance. In this utility model embodiment, the sealing cap 3 is provided with a receiving cavity 4 for containing desiccant. The cavity wall of the receiving cavity 4 is provided with several vent holes 5, which are designed to guide water vapor in the container body 1 into the receiving cavity 4 to be absorbed by the desiccant. The receiving cavity 4 is located outside the dispensing port 2, and there is a gap between the receiving cavity 2 and the dispensing port 2.

[0041] Specifically, the receiving cavity 4 is located inside the sealing cover 3 and is used to hold the desiccant. Several vent holes 5 are provided on its cavity wall. These vent holes 5 allow water vapor inside the canister body 1 to enter the receiving cavity 4 and be absorbed by the desiccant, thereby reducing the humidity inside the canister. It should be noted that the shape and size of the receiving cavity 4 can be set according to the internal space of the sealing cover 3, and are not limited here. For example, it can be circular or square, etc. The size and number of vent holes 5 can also be set according to actual needs, and are not limited here, as long as sufficient ventilation and prevention of desiccant particles from leaking into the canister body 1 are achieved.

[0042] To prevent a small amount of desiccant particles from leaking into the canister body 1, an isolation filter 12 can be installed at the opening of the dispensing port 2. The isolation filter 12 is designed to allow gas passage while blocking the passage of particulate powder. The isolation filter 12 can be made of existing high-density metal wire mesh or microporous filter membrane material to ensure good air permeability and filtration performance. By installing the isolation filter 12 at the dispensing port 2, the powdered medicine storage canister can effectively prevent drug particle leakage and the entry of external impurities while ensuring air circulation, further improving the safety and convenience of drug storage.

[0043] In this embodiment of the invention, the inner wall of the receiving cavity 4 is tightly fitted with the inner wall of the sealing cap 3, forming a relatively independent drying area. The vent 5 allows water vapor inside the canister body 1 to smoothly enter the receiving cavity 4 and be absorbed by the desiccant, which is then confined within the receiving cavity 4 and does not directly contact the medicine. Since the receiving cavity 4 is located outside the dispensing port 2 and there is a gap between them, the independence of the dispensing port 2 is ensured, preventing direct contact between the desiccant and the dispensing port 2, thus guaranteeing the convenience and safety of dispensing the medicine. The size of the gap can be designed according to actual needs, preferably between 1-3 mm. This gap ensures the normal operation of the vent 5 while preventing direct contact between desiccant particles and the dispensing port 2. The gap makes the dispensing port 2 and the receiving cavity 4 independent, so the user is not disturbed by the desiccant when dispensing the medicine, while also providing space for gas exchange through the vent 5.

[0044] In a preferred embodiment of this invention, the dispensing port 2 is configured with an upper opening, and the receiving cavity 4 is fixed to the top of the sealing cap 3 and faces the upper opening of the dispensing port 2. The receiving cavity 4 is located directly above the upper opening of the dispensing port 2. This structure can follow the direction of gas flow, allowing the desiccant in the receiving cavity 4 to directly act on the air above the dispensing port 2, more effectively absorbing water vapor entering from the dispensing port 2, thereby reducing the humidity inside the can. Of course, in other embodiments, the dispensing port 2 can also be configured as a side opening, and the receiving cavity 4 can also be fixed to the side of the sealing cap 3; there are no restrictions here.

[0045] For example, the bottom surface of the receiving cavity 4 is circular, and the upper opening of the dispensing port 2 is circular. The vertical projection of the upper opening of the dispensing port 2 falls into the bottom surface of the receiving cavity 4. The bottom surface of the receiving cavity 4 is provided with multiple vent holes 5. These vent holes 5 are evenly distributed on the bottom surface of the receiving cavity 4 to ensure sufficient ventilation and ensure the adsorption effect of the desiccant. The vent holes 5 allow air and water vapor entering from the dispensing port 2 to pass through. After entering the receiving cavity 4, they are absorbed by the desiccant, thereby reducing the humidity inside the can. By setting the vent holes 5 on the bottom surface of the receiving cavity 4, the air will fully contact the desiccant when entering the receiving cavity 4, further improving the drying effect and ensuring the uniformity of air circulation, thus avoiding premature failure of the desiccant in some areas. Preferably, there is a gap between the inner wall of the receiving cavity 4 and the sealing cover 3, and multiple vent holes 5 are provided on the side of the receiving cavity 4, so that air can enter the receiving cavity 4 from multiple directions and come into full contact with the desiccant, thereby more effectively absorbing moisture in the air. The existence of the gap allows air to circulate freely between the receiving cavity 4 and the sealing cover 3.

[0046] Furthermore, the canister body 1 includes an upper body 6 and a lower body 7. The lower body 7 is cylindrical, and the upper body 6 is arc-shaped. The lower end of the upper body 6 is open, and the upper end of the lower body 7 is open. The lower end of the upper body 6 and the upper end of the lower body 7 are detachably and sealingly connected. The medicine dispensing port 2 is located above the upper body 6, and the diameter of the upper opening of the medicine dispensing port 2 is smaller than the diameter of the upper opening of the lower body 7. Specifically, the upper body 6 and the lower body 7 are connected by a detachable and sealing connection, which facilitates the user to disassemble and clean the canister body 1 as needed, while ensuring airtightness. At the same time, medicine can be loaded using the upper end of the lower body 7 in the initial stage of loading because the opening is larger and more efficient. The smaller diameter of the upper opening of the medicine dispensing port 2 compared to the upper opening of the lower body 7 reduces the amount of outside air entering the canister.

[0047] like Figure 2 and Figure 3 As shown, in a preferred embodiment of this utility model, the dispensing port 2 is provided with a first step structure 8, the lower diameter of the first step structure 8 being larger than the upper diameter. This structure creates a stepped transition area in the vertical direction for the dispensing port 2, with its outer wall diameter gradually decreasing from bottom to top. The lower end of the first step structure 8 fits tightly with the upper body 6 of the can body 1, serving a positioning and sealing function, while the upper end provides more convenient space for dispensing medicine. When installed, the sealing cap 3 fits tightly with the lower end of the first step structure 8. Through the transition of the step structure, the sealing performance between the sealing cap 3 and the dispensing port 2 is ensured. The smaller diameter of the upper end of the first step structure 8 further reduces the amount of air entering the can during dispensing.

[0048] Of course, in another embodiment, a second step structure 9 can also be provided, such as... Figure 5 As shown, specifically, the dispensing port 2 is further provided with a second step structure 9, which is located above the first step structure 8. The lower diameter of the second step structure 9 is larger than the upper diameter; the upper diameter of the first step structure 8 is larger than the upper diameter of the second step structure 9. The second step structure 9 can further reduce the diameter of the opening at the upper end of the dispensing port 2. Of course, in other embodiments, a third step structure can also be provided sequentially. The specific arrangement can be determined according to actual needs and is not limited here.

[0049] Furthermore, to improve the installation flexibility of the receiving cavity 4, a support rod 10 is connected to the top inner side of the sealing cover 3. The support rod 10 is set vertically downwards, and its bottom is detachably connected to the receiving cavity 4. The support rod 10 enhances the overall structural stability of the sealing cover 3 and avoids the cumbersome direct installation of the receiving cavity 4 and the sealing cover 3. Through the detachable connection, users can easily remove the support rod 10 and the receiving cavity 4 for convenient replacement of the desiccant or cleaning.

[0050] Preferably, a sealing plug 11 is movably provided at the bottom of the sealing cap 3. The sealing plug 11 is designed to isolate and protect the desiccant inside the sealing cap 3 when the medicine is taken out. Specifically, the main function of the sealing plug 11 is to isolate the desiccant when the medicine is taken out, preventing the desiccant from directly contacting the outside air and avoiding desiccant failure. The sealing plug 11 is movable, making it easy to remove after taking out the medicine and to reinsert it when needed. Importantly, in the actual production process, the sealing plug 11, the sealing cap 3, and the receiving cavity 4 can be produced as a prefabricated unit, or the receiving cavity 4 can be produced as a prefabricated unit after adding desiccant. In this way, when the sealing cap 3 has been used for too long, a new sealing cap 3 can be directly replaced for continued use.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing techniques, and processes are omitted to avoid unnecessarily limiting the utility model.
