Description

Technical Field

[0001] This application relates to the technical field of packaging bags, and in particular to a desiccant packaging bag. Background Technology

[0002] In daily life, desiccants are widely used in various fields such as food, medicine, and electronic products to prevent items from becoming damp, deteriorating, or damaged. Existing desiccant packaging bags are usually made of breathable materials, and the desiccant material placed inside absorbs moisture in the enclosed space, thereby drying the enclosed space.

[0003] However, existing desiccant packaging bags have the drawback of not being able to visually indicate the current humidity level, requiring the inclusion of an additional humidity indicator card. Utility Model Content

[0004] To address the shortcomings of existing desiccant packaging bags that fail to visually indicate the current humidity level, this application provides a desiccant packaging bag.

[0005] The desiccant packaging bag provided in this application adopts the following technical solution:

[0006] A desiccant packaging bag, comprising:

[0007] Packaging leather;

[0008] A humidity indicator area is located on one side of the packaging skin, and a humidity indicator is provided in the humidity indicator area to indicate the humidity.

[0009] A waterproof and heat-insulating barrier sheet is fixedly connected to the packaging skin and positioned opposite the humidity indicator area.

[0010] By adopting the above technical solution, the packaging skin is the main part of the entire structure, serving to support and protect the internal items, preventing them from being physically damaged during transportation or storage, and providing a carrier for the installation and fixation of other components. The humidity indicator area is located on one side of the packaging skin and contains a humidity indicator to monitor changes in the current ambient humidity in real time. When the humidity changes, the humidity indicator will visually display the humidity level through color or other changes, thus reminding the user to take timely measures to prevent the items from being damaged by excessive humidity. The baffle is fixedly connected to the packaging skin and is set opposite to the humidity indicator area. Its main function is to provide waterproofing and heat insulation, preventing the humidity indicator area from being affected by the dry materials inside the packaging skin, and ensuring the accuracy of the humidity indication.

[0011] Preferably, the humidity indicator is provided in three locations: a first indicator block, a second indicator block, and a third indicator block. The first indicator block, the second indicator block, and the third indicator block correspond to different ranges of relative humidity in the current environment.

[0012] By adopting the above technical solution, the humidity indicator is placed in three locations: a first indicator block, a second indicator block, and a third indicator block. Each block corresponds to a different relative humidity of the current environment, resulting in more accurate and detailed humidity indication. This allows for a more comprehensive reflection of humidity changes inside or around the packaging, improving the accuracy and reliability of the humidity indicator. It avoids the ambiguity or error that may exist with a single indicator, enabling users to clearly understand the trend of humidity changes. No additional humidity measuring tools are needed; users can easily grasp the humidity situation simply by observing the indicator blocks on the packaging, and thus take timely measures, such as ventilation, drying, or adjusting storage conditions, to ensure the quality and performance of the goods in the current environment.

[0013] Preferably, the relative humidity of the current environment corresponding to the first indicator block is in the range of 4% to 12%, the relative humidity of the current environment corresponding to the second indicator block is in the range of 25% to 34%, and the relative humidity of the current environment corresponding to the third indicator block is in the range of 55% to 65%.

[0014] By adopting the above technical solution, the relative humidity range corresponding to the first indicator block is 4%~12%. This low humidity range is generally suitable for items that require a dry environment, such as certain electronic components, medicines, or precision instruments. By observing the changes in the first indicator block, users can intuitively determine whether the current environment is in an ideal dry state, promptly detect abnormal increases in humidity, and take appropriate measures. The relative humidity range corresponding to the second indicator block is 25%~34%. This medium humidity range is suitable for the storage conditions of most common items. When the second indicator block changes, users can clearly understand whether the current ambient humidity is at a moderate level, avoiding adverse effects on items due to excessively high or low humidity. For example, for some foods or textiles, maintaining this humidity range can effectively extend their shelf life or maintain their performance. The relative humidity range corresponding to the third indicator block is 55%~65%. This higher humidity range usually requires special attention from users. When the third indicator block changes, it indicates that the current ambient humidity has approached or reached a dangerous level that could cause items to become damp, moldy, or experience performance degradation. At this point, users can take timely measures, such as using desiccants, ventilation, or adjusting the storage environment, to prevent damage to the items due to excessive humidity. By clearly defining humidity ranges, users can more accurately grasp the humidity status inside the packaging, avoiding misjudgments caused by the ambiguity of a single humidity indicator. This meets the differentiated needs of different items with varying humidity sensitivities. Whether it's an item with extremely high requirements for a dry environment or a general item with a certain tolerance for humidity, it can be effectively monitored through the corresponding indicator block. This enhances the intelligence and user-friendliness of the packaging, allowing users to quickly understand the humidity situation simply by observing the indicator block without the need for additional humidity measurement equipment, thus enabling them to take timely and appropriate measures to ensure the quality and performance of the items in the current environment.

[0015] Preferably, the first indicator block, the second indicator block, and the third indicator block are all provided with an outer boundary for differentiation.

[0016] By adopting the above technical solution, the recognizability of the indicator blocks can be improved, especially in complex environments or low light conditions. Users can still quickly find the corresponding indicator block and judge the humidity status, ensuring that the indication effect of each indicator block is independent and accurate. The outer ring boundary can clearly separate the two, avoiding user confusion. In addition, the design of the outer ring boundary also enhances the overall aesthetics of the packaging, making the humidity indication area neater and more orderly, and improving the appearance quality of the product.

[0017] Preferably, the humidity indicator is a cobalt-free humidity indicator.

[0018] By adopting the above technical solutions, cobalt-free humidity indicators are environmentally friendly materials that avoid the pollution that cobalt elements may cause to the environment during production and use, while also reducing potential harm to human health. Cobalt-free humidity indicators have good chemical stability and reliability, and can accurately reflect humidity changes over a wide temperature range. The color changes of cobalt-free humidity indicators are usually more obvious, providing a more intuitive humidity indication effect, making it easier for users to quickly judge the humidity status.

[0019] Preferably, the packaging skin is a non-woven fabric-polyester composite skin.

[0020] By adopting the above technical solution, the nonwoven fabric-polyester composite leather combines the excellent properties of nonwoven fabric and polyester fiber, and has high strength, good breathability, water resistance and chemical corrosion resistance. It can effectively prevent external physical damage, such as scratches and collisions, and has high strength and durability, and can withstand certain pressure and friction during transportation and storage.

[0021] Preferably, the packaging skin is folded in half and then heat-sealed on three sides, forming a cavity for holding the dried material.

[0022] By adopting the above technical solution, the packaging skin is folded in half and the three sides are heat-sealed to form a cavity for holding the dry material. This ensures that the dry material is stably placed inside the packaging skin and prevents it from shifting or leaking during transportation or storage.

[0023] Preferably, the blocking sheet is disposed in the receiving cavity, and the blocking sheet is an aerogel sheet.

[0024] By adopting the above technical solution, aerogel is a material with extremely low thermal conductivity, which can effectively reduce heat transfer and has good waterproof performance. It can avoid interference between the humidity indicator area and the dry material, so that the humidity indicator area can relatively accurately indicate the humidity of the current environment. The aerogel sheet is lightweight and has high porosity, which will not significantly increase the weight.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The packaging skin is the main part of the entire structure, serving to support and protect the contents, preventing them from being physically damaged during transportation or storage, and providing a carrier for the installation and fixation of other components. The humidity indicator area is located on one side of the packaging skin and contains a humidity indicator to monitor changes in the current ambient humidity in real time. When the humidity changes, the humidity indicator will visually display the humidity level through color or other changes, thus reminding the user to take timely measures to prevent the items from being damaged by excessive humidity. The baffle is fixedly connected to the packaging skin and is set opposite to the humidity indicator area. Its main function is to provide waterproofing and heat insulation, preventing the humidity indicator area from being affected by the dry materials inside the packaging skin, and ensuring the accuracy of the humidity indication area.

[0027] 2. The humidity indicator is placed in three locations: the first indicator block, the second indicator block, and the third indicator block. Each block corresponds to a different relative humidity of the current environment, making the humidity indication more accurate and detailed. It can more comprehensively reflect the humidity changes inside or around the packaging, improving the accuracy and reliability of the humidity indication. It avoids the ambiguity or error that may exist with a single indicator, allowing users to more clearly understand the trend of humidity changes. No additional humidity measuring tools are needed; users can easily grasp the humidity situation by simply observing the indicator blocks on the packaging, and thus take timely measures, such as ventilation, drying, or adjusting storage conditions, to ensure the quality and performance of the goods in the current environment.

[0028] 3. The first indicator block corresponds to a relative humidity range of 4% to 12%. This low humidity range is generally suitable for items that require a dry environment, such as certain electronic components, medicines, or precision instruments. By observing the changes in the first indicator block, users can intuitively determine whether the current environment is in an ideal dry state and promptly detect and address any abnormal increases in humidity. The second indicator block corresponds to a relative humidity range of 25% to 34%. This medium humidity range is suitable for the storage conditions of most common items. When the second indicator block changes, users can clearly understand whether the current ambient humidity is at a suitable level, avoiding adverse effects on items due to excessively high or low humidity. For example, for some foods or textiles, maintaining this humidity range can effectively extend their shelf life or maintain their performance. The third indicator block corresponds to a relative humidity range of 55% to 65%. This higher humidity range usually requires special attention from users. When the third indicator block changes, it indicates that the current ambient humidity has approached or reached a dangerous level that could cause items to become damp, moldy, or experience performance degradation.

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a desiccant packaging bag. (Refer to...) Figure 1 and Figure 2 The desiccant packaging bag includes a packaging skin 1, a humidity indicator area 3, and a barrier sheet 5.

[0037] like Figure 1 and Figure 2 As shown, the packaging skin 1 is a non-woven fabric-polyester composite skin. When unfolded, the packaging skin 1 is rectangular. The packaging skin 1 is the main part of the entire structure, which plays the role of supporting and protecting the contents. It can prevent the contents from being physically damaged by the outside world during transportation or storage, and at the same time provide a carrier for the installation and fixation of other components. The non-woven fabric-polyester composite skin combines the excellent properties of non-woven fabric and polyester fiber. It has high strength, good breathability, water resistance and chemical corrosion resistance. It can effectively prevent external physical damage, such as scratches and collisions, and has high strength and durability. It can withstand a certain amount of pressure and friction during transportation and storage.

[0038] Please refer to Figure 3 and Figure 4 In this embodiment of the application, the packaging skin 1 is folded in half and the three sides are heat-sealed. The packaging skin 1 forms a cavity 2 for placing the dry material. Folding the packaging skin 1 in half and heat-sealing the three sides forms a cavity 2 for placing the dry material, which ensures the stable placement of the dry material in the packaging skin 1 and prevents it from shifting or leaking during transportation or storage.

[0039] like Figure 1 As shown, the humidity indicator area 3 is located on one side of the packaging skin 1, and a humidity indicator is provided inside the humidity indicator area 3 for indicating humidity. The humidity indicator area 3 is located on one side of the packaging skin 1, and a humidity indicator is provided inside it for real-time monitoring of the humidity changes in the current environment. When the humidity changes, the humidity indicator will intuitively display the humidity level through color or other changes, thereby reminding the user to take timely measures to prevent the items from being damaged by excessive humidity.

[0040] In this embodiment, the humidity indicator is provided in three locations: a first indicator block 31, a second indicator block 32, and a third indicator block 33. The first indicator block 31, the second indicator block 32, and the third indicator block 33 correspond to different ranges of relative humidity in the current environment. Each indicator block corresponds to a different relative humidity in the current environment, making the humidity indication more accurate and detailed. It can more comprehensively reflect the humidity changes inside or around the packaging, improve the accuracy and reliability of the humidity indication, avoid the ambiguity or error that may exist with a single indicator, and allow users to more clearly understand the trend of humidity changes. Without the need for additional humidity measuring tools, users can easily grasp the humidity situation by simply observing the indicator blocks on the packaging, and thus take timely measures, such as ventilation, drying, or adjusting storage conditions, to ensure the quality and performance of the items in the current environment.

[0041] For example, the relative humidity range of the current environment corresponding to the first indicator block 31 is 4% to 12%. This low humidity range is usually suitable for items that require a dry environment, such as certain electronic components, medicines, or precision instruments. By changing the first indicator block 31, users can intuitively determine whether the current environment is in an ideal dry state, and promptly detect and deal with abnormal increases in humidity.

[0042] For example, the relative humidity range of the current environment corresponding to the second indicator block 32 is 25% to 34%. This moderate humidity range is suitable for the storage conditions of most common items. When the second indicator block 32 changes, the user can clearly understand whether the current ambient humidity is at a moderate level, avoiding adverse effects on the items due to excessively high or low humidity. For example, for some foods or textiles, maintaining this humidity range can effectively extend their shelf life or maintain their performance.

[0043] For example, the relative humidity range corresponding to the third indicator block 33 is 55% to 65%. This relatively high humidity range usually requires special attention from the user. When the third indicator block 33 changes, it indicates that the current ambient humidity has approached or reached a dangerous level that may cause the items to become damp, moldy, or experience performance degradation. At this time, the user can take timely measures, such as further using desiccants, ventilation, or adjusting the storage environment, to prevent the items from being damaged due to excessive humidity.

[0044] Specifically, by using the first indicator block 31, the second indicator block 32, and the third indicator block 33 to represent different ranges of relative humidity in the current environment, users can more accurately grasp the humidity status inside the packaging, avoiding misjudgments caused by the ambiguity of a single humidity indicator. This meets the differentiated needs of different items regarding their humidity sensitivity. Whether it is an item with extremely high requirements for a dry environment or an ordinary item with a certain tolerance for humidity, it can be effectively monitored through the corresponding indicator blocks. This enhances the intelligence and user-friendliness of the packaging, allowing users to quickly understand the humidity situation simply by observing the indicator blocks without the need for additional humidity measuring equipment, and thus take timely measures to ensure the quality and performance of the items in the current environment.

[0045] For example, the humidity indicator is a cobalt-free humidity indicator. Cobalt-free humidity indicators are environmentally friendly materials that avoid the pollution that cobalt elements may cause to the environment during production and use, and also reduce potential harm to human health. Cobalt-free humidity indicators have good chemical stability and reliability, and can accurately reflect humidity changes over a wide temperature range. The color changes of cobalt-free humidity indicators are usually more obvious, providing a more intuitive humidity indication effect, making it easier for users to quickly judge the humidity status. Cobalt-free humidity indicators are existing technology. In this application, the first indicator block 31, the second indicator block 32, and the third indicator block 33 formed by the cobalt-free humidity indicator can achieve a relative humidity range of 4%~12%, 25%~34%, and 55%~65% for the current environment, respectively. This application does not impose specific restrictions on the materials and proportions of the cobalt-free humidity indicator.

[0046] It should be noted that, in this embodiment of the application, the first indicator block 31, the second indicator block 32 and the third indicator block 33 are all provided with an outer ring boundary 4 for differentiation. The outer ring boundary 4 is a thick black ring. The outer ring boundary 4 can improve the recognizability of the indicator blocks. Especially in complex environments or in low light conditions, users can still quickly find the corresponding indicator block and judge the humidity status, ensuring that the indication effect of each indicator block is independent and accurate. The outer ring boundary 4 can clearly separate the two and avoid user confusion. In addition, the design of the outer ring boundary 4 also enhances the overall aesthetics of the packaging, making the humidity indication area 3 neater and more orderly, and improving the appearance quality of the product.

[0047] like Figure 2 and Figure 5 As shown, the blocking sheet 5 is fixedly connected to the packaging skin 1 and is set opposite to the humidity indication area 3. The blocking sheet 5 is used for waterproofing and heat insulation to prevent the humidity indication area 3 from being affected by the dry material inside the packaging skin 1, and to ensure the accuracy of the humidity indication in the humidity indication area 3.

[0048] In this embodiment, the blocking sheet 5 is disposed in the receiving cavity 2 to reduce heat transfer and block moisture, prevent the humidity indicating area 3 from interfering with the drying material, and enable the humidity indicating area 3 to indicate the humidity of the current environment relatively accurately.

[0049] For example, in this embodiment of the application, the blocking sheet 5 is an aerogel sheet; aerogel is a material with extremely low thermal conductivity, which can effectively reduce heat transfer and has good waterproof performance, which can reduce heat transfer and block moisture, and prevent the humidity indicator area 3 from interfering with the desiccant material; at the same time, the aerogel sheet has the characteristics of being lightweight and having high porosity, which will not significantly increase the weight, ensuring the lightweight of the desiccant packaging bag; the blocking sheet 5 is fixedly connected to the packaging skin 1 by means including but not limited to adhesives and / or sewing.

[0050] It should be noted that the blocking sheet 5 in this application only needs to reduce heat transfer and block moisture. This application does not impose specific limitations on the specific material and / or structure of the blocking sheet 5.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
