[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Please refer to Figures 1-5This utility model provides a technical solution: an air column bag for toner cartridge packaging, including an air column bag body 1, the air column bag body 1 including multiple sets of air column units 11, each set of air column units 11 having a hot-pressing edge structure 12 on both sides, a sponge connecting strip 13 between two adjacent sets of air column units 11, one end of the sponge connecting strip 13 being fixedly connected to the hot-pressing edge structure 12 of one side of the air column unit 11, the other end of the sponge connecting strip 13 being fixedly connected to the hot-pressing edge structure 12 of the other side of the air column unit 11, and an inflation / deflation connecting strip 14 between two adjacent sets of air column units 11.

[0025] A sponge connecting strip 13 is added at the connection point of multiple air column units 11. The sponge connecting strip 13 is made of polyurethane sponge, which has high resilience and can produce a certain elastic deformation when subjected to external force. It is also inexpensive, effectively saving production costs. Figure 1 and Figure 2 As shown, a sponge connecting strip 13 is added between two adjacent sets of air column units 11, so that the connection between the two adjacent sets of air column units 11 is elastic. When a certain external force is applied to the air column bag body 1, the multiple sets of sponge connecting strips 13 at the connection point produce corresponding elastic deformation, which can increase the size of the placement chamber of the air column bag body 1. When the toner cartridge body is placed in the placement chamber, the multiple sets of air column units 11 of the air column bag body 1 can be tightly attached to the outside of the toner cartridge body, providing comprehensive protection for the toner cartridge body and preventing the toner cartridge body from falling off.

[0026] The chambers of each air column unit 11 are connected by multiple sets of inflation / deflation connecting strips 14, which facilitates the subsequent inflation / deflation of the air column bag body 1. The inflation / deflation connecting strips 14 have a certain length and can change accordingly with the shape of the air column bag body 1.

[0027] Multiple air column units 11 and multiple sponge connecting strips 13 are connected together to form a ring structure, and the ring structure is provided with a placement cavity for placing the toner cartridge.

[0028] The inflation / deflation connecting strip 14 includes an inflation / deflation connecting air passage.

[0029] One end of the inflation / deflation connecting strip 14 is connected to the chamber of one side air column unit 11, and the other end of the deflation connecting strip 14 is connected to the chamber of the other side air column unit 11. The inflation / deflation connecting air passage of the inflation / deflation connecting strip 14 connects the chambers of the air column units 11 on both sides.

[0030] The air column bag body 1 has an inflation port 15 on one of its air column units 11. The inflation port 15 is connected to the chamber of the air column unit 11, and the air column bag body 1 is inflated and deflated through the inflation port 15.

[0031] The air inlet 15 is equipped with a reverse air stop valve membrane, which is a commonly used air valve membrane on the market. The reverse air stop valve membrane consists of two tightly fitted valve membranes. The air inlet 15 is equipped with an air inlet channel. After the air column bag body 1 is inflated, the two membranes are pressed to the same side, thereby closing the gas backflow channel and realizing the air lock function. When deflation, a straw can be inserted into the air inlet 15 and the air column units 11 of the air column bag body 1 can be manually squeezed to expel the gas. The air column bag body 1 can be inflated and deflated, is easy to store and can be reused.

[0032] Specifically, the toner cartridge to be packaged is placed into the placement cavity, and the toner cartridge is packaged and protected by the air column bag body 1. The size of the air column bag body 1 is adapted to the specifications and dimensions of the toner cartridge. Multiple air column units 11 are tightly attached to the outside of the toner cartridge under the elasticity of the sponge connecting strip 13, wrapping the toner cartridge and effectively preventing it from falling off. The air column bag body 1 is a complete packaging bag structure. During packaging, there is no need to cut or use tape to fix it, making it convenient to use.

[0033] The air column bag body 1 has openings at both ends. When packaging toner cartridges, the toner cartridges to be packaged are inserted into the openings at both ends of the air column bag body 1.

[0034] In this invention, during use, the air column bag body 1 is inflated. An inflation tool is inserted through the inflation port 15, and the inflated gas causes each air column unit 11 to expand. The reverse check valve membrane at the inflation port 15 consists of two tightly fitted valve membranes. After the air column bag body 1 is inflated, the two membranes are pressed to the same side, thereby closing the gas backflow channel and achieving the air-locking function. The toner cartridge to be packaged is inserted into the placement cavity through the openings at both ends of the air column bag body 1. Because the sponge connecting strip 13 is made of polyurethane sponge, which has high resilience, it can produce a certain elastic deformation when subjected to external force, allowing the air column bag body 1 to expand. The size of the cavity is flexibly adjustable, so the size of the air column bag body 1 adapts to the specifications and dimensions of the toner cartridge. Multiple air column units 11 are tightly attached to the outside of the toner cartridge under the elasticity of the sponge connecting strip 13, wrapping the toner cartridge and effectively preventing it from falling off. It can be understood that the air column bag body 1 is a complete packaging bag structure, and no tape is needed to fix it during packaging. In addition, when deflating the air column bag body 1, a straw can be inserted into the inflation port 15 and the air column units 11 of the air column bag body 1 can be manually squeezed to expel the gas. Thus, the air column bag body 1 can be inflated and deflated, is easy to store, and can be reused.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
