Description

Technical Field

[0001] This utility model relates to the field of chemical storage technology, and in particular to a dry chemical storage packaging bottle. Background Technology

[0002] Currently, most chemicals used in laboratories of universities and research institutes are required to be moisture-proof. Some chemicals are prone to deliquescence once their packaging is opened, and even when stored in ordinary medicine bottles without desiccants, frequent opening and closing of the caps can easily cause deliquescence. Once chemicals become deliquescent, the weight of the chemicals measured during the weighing process will be significantly inaccurate, affecting experimental results and causing considerable inconvenience to staff. Currently, there is no reliable technical solution for this problem. Utility Model Content

[0003] The purpose of this application is to provide a dry chemical storage packaging bottle to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: a dry chemical storage packaging bottle, comprising an inner bottle body, an outer bottle body, an upper cap, and a lower cap. The inner bottle body is disposed inside the outer bottle body, the inner bottle body and the outer bottle body are coaxial, and the inner bottle body and the outer bottle body are fixedly connected. An annular drying cavity is formed between the outer wall of the inner bottle body and the inner wall of the outer bottle body, surrounding the axis of the inner bottle body. The drying cavity is filled with a desiccant. The outer wall of the inner bottle body is provided with a plurality of vent holes, which communicate with the drying cavity. The top of the inner bottle body is open and its bottom is closed. The bottom of the drying cavity is open. The top of the outer bottle body is fitted with an upper cap that seals the top of the inner bottle body, and the bottom of the outer bottle body is fitted with a lower cap that seals the drying cavity.

[0005] Preferably, both the upper and lower caps are threadedly connected to the outer wall of the outer bottle body.

[0006] Preferably, a label is adhered and fixed to the outer wall of the outer bottle, and a waterproof film is fixedly installed on the outside of the label.

[0007] Preferably, a first sealing ring adapted to seal the outer bottle body is fixedly installed on the inner side wall of the upper cap.

[0008] Preferably, a second sealing ring adapted to seal the outer bottle body is fixedly installed on the inner side wall of the lower end cap.

[0009] Preferably, the particle size of the desiccant is larger than the diameter of the vent hole.

[0010] In summary, the technical effects and advantages of this utility model are as follows:

[0011] In this invention, the chemicals inside the inner bottle can be poured out and used by opening the upper cap, without spilling the desiccant. The desiccant inside the drying chamber can be poured out and replaced by opening the lower cap, without spilling the chemicals. This allows for independent storage, and the desiccant can absorb moisture inside the inner bottle through the vent, ensuring reliable storage of the chemicals. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] It should also be noted that all standard parts used in this application are commercially available, and can be custom-made according to the description and drawings. Unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances, and unless explicitly limited, machinery, parts, and equipment can all adopt conventional models in the prior art.

[0019] In this document, the term "comprising" is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0020] Example: Reference Figure 1-2 The illustrated drying chemical storage packaging bottle includes an inner bottle body 1, an outer bottle body 2, an upper cap 6, and a lower cap 7. The inner bottle body 1 is disposed inside the outer bottle body 2. The inner bottle body 1 and the outer bottle body 2 are coaxial and fixedly connected. An annular drying cavity 3 is formed between the outer wall of the inner bottle body 1 and the inner wall of the outer bottle body 2, surrounding the axis of the inner bottle body 1. The drying cavity 3 is filled with a desiccant 4. The outer wall of the inner bottle body 1 has several vent holes 5, which communicate with the drying cavity 3. The inner bottle 1 has an open top and a closed bottom. The drying chamber 3 has an open bottom. The outer bottle 2 has an upper cap 6 that seals the top of the inner bottle and a lower cap 7 that seals the drying chamber 3. The chemicals in the inner bottle can be poured out by opening the upper cap, but the desiccant will not spill out. The desiccant in the drying chamber can be poured out and replaced by opening the lower cap, but the chemicals will not spill out. This allows for independent storage. The desiccant can absorb moisture in the inner bottle through the vent, ensuring reliable storage of the chemicals.

[0021] With the above structure, both the upper cap 6 and the lower cap 7 are threadedly connected to the outer wall of the outer bottle body 2.

[0022] With the above structure, a label 8 is adhered and fixed to the outer wall of the outer bottle 2, and a waterproof film 9 is fixedly installed on the outside of the label 8 for water-blocking protection to prevent the label from becoming blurred or falling off.

[0023] With the above structure, a first sealing ring 10 that is adapted to seal the outer bottle body 2 is fixedly installed on the inner side wall of the upper cap 6.

[0024] With the above structure, a second sealing ring 11 that is adapted to seal the outer bottle body 2 is fixedly installed on the inner side wall of the lower end cap 7.

[0025] With the above structure, the particle size of the desiccant 4 is larger than the diameter of the vent 5, which can prevent the desiccant from entering the interior of the chemical.

[0026] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
