Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and more specifically, to a pharmaceutical packaging box. Background Technology

[0002] As a special commodity, the quality and safety of pharmaceuticals are directly related to human health and life. Any improper handling during production, storage, and transportation can affect their efficacy or even create safety hazards. Temperature is one of the most critical factors affecting the stability and effectiveness of pharmaceuticals during storage and transportation. Many biological agents, vaccines, blood products, and some chemical drugs must be transported under strictly constant temperature conditions (such as a low-temperature environment of 2-8°C) to ensure that their active ingredients do not degrade or denature.

[0003] Currently, for long-distance, large-volume drug transportation, specialized refrigerated transport vehicles equipped with temperature control systems and real-time monitoring equipment are typically used to maintain a stable low-temperature environment during transportation, effectively ensuring drug quality. However, this cold chain transportation method is costly and mainly used for cross-regional or large-scale distribution scenarios. In short-distance transportation scenarios, such as the "last mile" delivery from regional distribution centers to hospital pharmacies, community clinics, or retail pharmacies, dedicated temperature-controlled transport equipment is often lacking. In practice, short-distance transportation typically involves placing ice packs or ice blocks inside or around the medicine box for cooling. While this method is simple to operate and low-cost, it has several technical drawbacks: First, the ice packs or ice blocks release cold energy unevenly, easily causing uneven temperature distribution inside the medicine box. Second, as the ice packs melt, the humidity inside the box rises sharply and condensation occurs, easily soaking the medicine box and making subsequent handling difficult. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a medicine packaging box to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A pharmaceutical packaging box includes a packaging box body, with loading and unloading slots on each side of the interior of the packaging box body. A phase change cold storage plate is slidably installed inside the loading and unloading slots. The phase change cold storage plate is filled with a phase change material. A positioning block is connected to one end of the phase change cold storage plate, and a limiting groove is opened at the other end. The positioning block and the limiting groove cooperate with each other.

[0007] Furthermore, in order to achieve the moisture-proof and moisture-absorbing effect inside the packaging box, a dehumidification groove is opened at the bottom of the inner wall of the packaging box. A protective cover is slidably installed inside the dehumidification groove. Moisture-absorbing holes are opened on the surface of the protective cover. The dehumidification groove is filled with desiccant.

[0008] Furthermore, in order to achieve the heat insulation effect of the packaging box and slow down the heating rate of the internal phase change cold storage plate, a heat insulation layer is provided on the outer surface of the packaging box.

[0009] Furthermore, to prevent condensate generated on the surface of the phase change cold storage plate from seeping into the packaging box, a waterproof membrane is installed on the inner wall of the loading and unloading trough.

[0010] Furthermore, in order to facilitate the filling of phase change material inside the phase change cold storage plate, a filling port is provided on one side of the surface of the phase change cold storage plate, and a sealing cap is installed on the top of the filling port.

[0011] Furthermore, in order to achieve a waterproof effect on the inner and outer surfaces of the packaging box, a waterproof membrane is provided on the inner wall of the packaging box and the outer surface of the insulation layer.

[0012] Furthermore, in order to seal the opening at the top of the packaging box, lids are provided on both sides of the top of the packaging box.

[0013] Furthermore, in order to facilitate the lifting of the phase change cold storage plate from the loading and unloading tank, a lifting groove is opened on one side of the surface of the phase change cold storage plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The phase change cold storage plate is filled with a phase change material with a specific phase change temperature. After absorbing and storing cold energy during the pre-cooling process, the phase change material can stably release cold energy during transportation, maintaining a constant temperature environment inside the box. By splicing and installing various phase change cold storage plates inside the packaging box, the cold source is evenly distributed around the box, significantly improving the uniformity of the temperature field inside the box. Multiple phase change cold storage plates are spliced ​​and arranged around the inner wall of the packaging box to form a ring-shaped temperature control structure, which not only increases the contact area for cold energy release but also enhances the continuity and stability of cold energy transfer. This allows the space inside the box to quickly reach and maintain the required low temperature range for a long time, extending the duration of constant temperature and effectively ensuring the stability and safety of the medicine throughout the transportation process.

[0016] 2. By splicing and installing phase change cold storage plates on each side inside the packaging box, the overall structural strength of the packaging box can be effectively enhanced. Compared with traditional paper medicine packaging boxes, the packaging box has a stronger load-bearing capacity when loading and handling medicines and when subjected to external impacts. It is not easy to deform or be damaged, which greatly improves the protection of the medicines inside. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] According to an embodiment of the present invention, a medicine packaging box is provided.

[0028] like Figures 1-5As shown, a pharmaceutical packaging box according to an embodiment of the present invention includes a paper packaging box body 1. Each side of the packaging box body 1 has a loading / unloading groove 2. An aluminum alloy phase change cold storage plate 3 is slidably installed inside the loading / unloading groove 2. The phase change cold storage plate 3 is filled with a phase change material (different phase change materials, such as paraffin mixtures or fatty acids, can be filled according to different temperature requirements). One end of the phase change cold storage plate 3 is connected to a positioning block 4, and the other end has a limiting groove 5. The positioning block 4 cooperates with the limiting groove 5. When it is necessary to transport the medicine inside the packaging box body 1 at low temperature, each phase change cold storage plate 3, after cold storage, is slidably installed in the loading / unloading groove 2. The positioning blocks 4 and limiting grooves 5 at both ends of the cold storage plate are mutually coordinated to achieve end-to-end splicing, thus ensuring its proper installation inside the packaging box body 1. The phase change material inside the phase change cold storage plate 3 absorbs and stores cold energy during the pre-cooling process and can stably release cold energy into the box body during transportation, maintaining a constant temperature environment inside the box.

[0029] like Figures 1-6 As shown, a dehumidification groove 6 is opened at the bottom of the inner wall of the packaging box 1. A protective cover 7 is slidably installed inside the dehumidification groove 6. Moisture absorption holes 8 are opened on the surface of the protective cover 7. The dehumidification groove 6 is filled with desiccant, which can absorb moisture and prevent dampness inside the box through the desiccant in the dehumidification groove 6. A heat insulation layer 9 is provided on the outer surface of the packaging box 1 to achieve the heat insulation effect of the packaging box 1 and slow down the heating rate of the internal phase change cold storage plate 3. A waterproof membrane 10 is provided on the inner wall of the loading and unloading groove 2 to prevent condensate generated on the surface of the phase change cold storage plate 3 from seeping into the packaging box 1. The surface of the phase change cold storage plate 3 is... A filling port 11 is provided on one side of the packaging box 1, and a sealing cap 12 is installed on the top of the filling port 11. The phase change material is conveniently injected into the phase change cold storage plate 3 by opening the sealing cap 12. The inner wall of the packaging box 1 and the outer surface of the heat insulation layer 9 are provided with a waterproof membrane 13 to achieve the waterproof effect of the inner and outer surfaces of the packaging box 1. The top two sides of the packaging box 1 are provided with box covers 14, which are used to close the top opening of the packaging box 1 after being rotated. A lifting groove 15 is opened on one side of the surface of the phase change cold storage plate 3. By pulling the lifting groove 15, the phase change cold storage plate 3 can be conveniently slid out of the loading and unloading groove 2.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical use, before use, a phase change material with a suitable phase change temperature (such as paraffin mixture, fatty acids, etc.) is selected according to the temperature control requirements of the medicine to be transported. This material is injected into the inner cavity of the phase change cold storage plate 3 through the injection port 11, and then the sealing cap 12 is placed on top to ensure airtightness. Subsequently, multiple phase change cold storage plates 3 are placed in a low-temperature environment for pre-cooling treatment, allowing the internal phase change material to fully solidify and store cold energy. Simultaneously, the dehumidification tank 6 at the bottom of the packaging box 1 is pre-filled with desiccant and covered with a protective cap 7 with moisture-absorbing holes 8 to continuously absorb excess moisture inside the box during transportation, preventing moisture accumulation. When the medicine inside the packaging box 1 needs to be transported, the pre-cooled phase change cold storage plate 3 is removed from the cold storage and slid into the loading / unloading groove 2 on the inner wall of the packaging box 1 via the lifting groove 15. During installation, the positioning block 4 at one end of each phase change cold storage plate 3 is inserted into the limiting groove 5 of the adjacent cold storage plate, achieving end-to-end splicing and tight connection, thus forming a surrounding, seamless low-temperature barrier structure around the packaging box 1. This splicing method not only ensures the uniform release of cold energy inside the box and avoids temperature dead zones, but also enhances the structural stability between the cold storage plates and reduces vibration and displacement during transportation. During transportation, the phase change material inside the phase change cold storage plate 3 gradually absorbs heat and undergoes a phase change, absorbing a large amount of heat and maintaining a basically constant temperature, thereby maintaining the space inside the box at a stable low temperature.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
