Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a breathable and absorbent bag. Background Technology

[0002] Breathable absorbent bags are products that absorb moisture from the surrounding environment to reduce humidity. These bags are usually made of absorbent materials such as silicone or molecular sieves, and are placed directly or hung in areas that need to be kept dry, such as wardrobes or drawers.

[0003] To ensure the absorbency of breathable and absorbent bags, desiccants are typically placed inside. During use, the desiccant absorbs more moisture, keeping the surrounding environment dry. After use, sun exposure removes moisture, allowing for reuse. However, due to the material properties of the bag, moisture evaporates slowly during sun exposure. Additionally, the desiccant tends to accumulate at the bottom of the bag due to gravity, reducing the effective absorption area and causing the desiccant to clump together, rendering sun exposure ineffective and forcing the bag to be discarded – a waste. Therefore, a breathable and absorbent bag is provided to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a breathable and absorbent bag that solves the problems of slow moisture expulsion during sun exposure due to the overall material properties of the bag, the accumulation of desiccant at the bottom of the bag under gravity, the reduction of effective absorbent area, and the clumping of desiccant after use, which prevents it from regaining its original effectiveness after sun exposure and necessitates disposal.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a breathable and absorbent bag, comprising a bag body, wherein the two sides of the bag body are respectively bonded together with plastic film and absorbent paper;

[0006] A self-sealing zipper is provided on one side of the plastic film;

[0007] The absorbent paper has multiple equidistant dividers on its inner side, which divide the inside of the bag into multiple independent storage chambers.

[0008] Preferably, easy-tear points are provided between the plurality of bags.

[0009] Preferably, the bag body is provided with a plastic seal around its perimeter, and the plastic seal is a 1 cm wide hot-stamped line.

[0010] Preferably, a hanging ring is integrally formed on the outer side of one of the plastic-sealed edges, and the hanging ring is on the same side as the self-sealing zipper.

[0011] Preferably, the plastic film has an opening for sealing, and the self-sealing zipper is fixedly attached to the inside of the opening.

[0012] Preferably, a protective layer is fixedly adhered to the inner side of the absorbent paper, and the separator is integrally formed with the inner side of the protective layer.

[0013] Preferably, the plastic film is made of PA or PE material.

[0014] This utility model discloses a breathable and absorbent bag, which has the following beneficial effects: the interior of the breathable and absorbent bag is divided into multiple independent storage chambers by a separator, so that the desiccant can avoid direct accumulation at the bottom during storage, effectively increasing the contact surface of the desiccant during the adsorption process. At the same time, the self-sealing zipper allows for easy access to the desiccant, making it convenient to add the desiccant during processing. During use, the user can also take out the desiccant through the self-sealing zipper for exposure to the sun, effectively and quickly removing the moisture from the desiccant. When the desiccant is completely ineffective, it can be easily replaced with new desiccant. It is convenient to use and effectively reduces replacement costs. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application provides a breathable and absorbent bag that solves the problems of existing breathable and absorbent bags, which suffer from slow moisture expulsion during sun exposure due to the overall material properties of the bag. Additionally, during use, the desiccant tends to accumulate at the bottom of the bag under gravity, reducing the effective absorbent area. Furthermore, after use, the desiccant often clumps together, making it impossible to restore its original effectiveness with sun exposure alone, resulting in wasteful disposal.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a breathable and absorbent bag.

[0025] Example 1

[0026] According to the appendix Figure 1-4 As shown, it includes a bag body 1, and the two sides of the bag body 1 are respectively bonded together with plastic film 12 and absorbent paper 11;

[0027] A self-sealing zipper 19 is provided on one side of the plastic film 12. The desiccant can be put in and taken out through the self-sealing zipper 19, which is convenient for adding desiccant during processing. At the same time, the user can also take out the desiccant through the self-sealing zipper 19 for sun exposure, which can effectively and quickly remove the moisture in the desiccant. When the desiccant is completely ineffective, it can be easily replaced with new desiccant. Unlike the form of direct opening, it can prevent the desiccant from scattering during use.

[0028] Multiple bags 1 are provided with easy-tear points 2, which allows multiple bags 1 to be continuously generated and connected in sequence during actual production. This facilitates quick and accurate retrieval of a specified quantity during subsequent packaging. When in use, users can quickly tear open a single bag 1 along the easy-tear points 2 to retrieve it, making it easy to store and use.

[0029] The bag body 1 is provided with a plastic sealing edge 13 around its perimeter. The plastic sealing edge 13 is a 1 cm wide hot-stamped line, which enables the entire bag body 1 to form an effective sealed space except for the opening 14, preventing the internal desiccant from leaking out.

[0030] A set of plastic-sealed edges 13 has an integrally formed hanging loop 15 on the outer side. The hanging loop 15 is on the same side as the self-sealing zipper 19, and the hanging loop 15 makes it convenient to hang the breathable and absorbent bag in cabinets or other places.

[0031] The plastic film 12 has an opening 14, and the self-sealing zipper 19 is fixedly attached to the inside of the opening 14.

[0032] The plastic film 12 is made of PA or PE material, which gives the entire plastic film 12 good ductility and ultra-long service life.

[0033] Working principle: When in use, the device fills the bag body 1 formed by bonding the plastic film 12 and the absorbent paper 11 with desiccant, and then hangs it in the designated applicable place using the hanging ring 15. At this time, the moisture in the outside air enters the bag body 1 through the absorbent paper 11 and is absorbed by the desiccant and absorbent paper 11, thereby achieving the dehumidification effect.

[0034] Example 2

[0035] According to the appendix Figure 1-4 As shown, based on Embodiment 1, more specifically, the absorbent paper 11 has a plurality of equidistant partitions 17 on its inner side, which divide the inside of the bag body 1 into a plurality of independent storage chambers 18.

[0036] A protective layer 16 is fixedly adhered to the inner side of the absorbent paper 11, and the separator 17 is integrally formed with the inner side of the protective layer 16.

[0037] Working principle: The device uses a separator 17 to divide the inside of the breathable and absorbent bag into multiple independent storage chambers 18, which prevents the desiccant from accumulating directly at the bottom during storage, effectively increasing the contact surface of the desiccant during the adsorption process, and also making it easy to remove the desiccant after use.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
