Description

Technical Field

[0001] The present application relates to the technical field of dry ice transport packaging, and in particular to a dry ice transport packaging bag. Background Art

[0002] Dry ice is solid carbon dioxide and is often used in food refrigeration, cloud effects in stage and film, and industrial cleaning.

[0003] Dry ice is generally processed into blocks and transported in foam boxes or insulated boxes. Common dry ice transport packaging currently on the market includes a dry ice transport box with patent publication number CN211167996U, which includes a box body and a box lid. The box body is provided with a box shell, an explosion-proof layer, an isolation layer, and an inner insulation layer from the outside to the inside. The inner insulation layer includes a tin foil reflective layer, a buffer layer, and an inner jacket layer from the outside to the inside. The inner jacket layer is an insulated aluminum film bag nested inside the box body. The inner jacket layer is provided with a zipper and a handle. The utility model provides an explosion-proof layer between the box body and the isolation layer to avoid explosions caused by excessive pressure due to the volatilization of dry ice, thereby preventing personal injury. A polyurethane soft foam buffer layer is added to the inner side of the box body to effectively reduce collisions of dry ice during transportation and reduce volatilization. An insulated aluminum film bag is nested on the innermost side of the box body to facilitate the loading and unloading of dry ice, thereby preventing frostbite caused by accidental contact with dry ice.

[0004] However, the above-mentioned box is a hard box, which results in the box occupying a large space during transportation after loading and unloading, making it inconvenient to transport. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a dry ice transport packaging bag, which has the advantages of facilitating the turnover and transportation of dry ice while reducing dry ice transportation losses.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0007] A dry ice transport packaging bag, comprising a flexible heat-insulating bag body, wherein the flexible heat-insulating bag body is provided with a material access opening on both the upper and lower sides, wherein the material access opening is provided with a closure member for blocking the material access opening, and a pair of carrying straps are provided on the side walls of the flexible heat-insulating bag body;

[0008] The closure member comprises a plurality of blocking pieces which are arranged at equal intervals along the circumference of the material taking-in and discharging opening, and a binding rope is passed through the plurality of blocking pieces.

[0009] To implement the above technical solution, dry ice can be placed into the flexible insulation bag through the loading and unloading port on the top of the flexible insulation bag to complete the loading of dry ice. After loading is completed, the loading and unloading port is sealed by a sealing member to prevent leakage of dry ice blocks. When unloading is required, the loading and unloading port is opened by simply using the carrying strap, so that the dry ice can fall out under its own gravity, facilitating turnover of loading and unloading. Moreover, because the entire flexible insulation bag is flexible, it can be folded and stacked after loading and unloading, facilitating batch turnover.

[0010] As a preferred solution of the present application, the blocking piece is integrally provided with the flexible heat-insulating bag body, and the end of the blocking piece is folded inwardly and sewn to form a cinch ring for the cinch rope to pass through.

[0011] To implement the above technical solution, the tightening rope passes through different tightening rings to connect several blocking pieces, and then controls the blocking pieces to retract and open.

[0012] As a preferred solution of the present application, each of the sealing pieces is sewn with an extension cloth on one side inside the flexible heat-insulating bag body, and the extension cloths are staggered and stacked.

[0013] To implement the above technical solution, the extended cloths are staggered and stacked to seal the gaps between the several sealing pieces; and when loading is required, the sealing pieces can be pulled upward to form a "guide tube" to facilitate the loading of dry ice.

[0014] As a preferred solution of the present application, the flexible insulation bag body includes a plurality of insulation sheets, and the plurality of insulation sheets are sewn and fixed.

[0015] By implementing the above technical solution, the flexible thermal insulation bag body is sewn from the thermal insulation sheet, so that the flexible thermal insulation bag body can be folded along the sewn seam to reduce the occurrence of thermal insulation sheet damage due to repeated folding.

[0016] As a preferred solution of the present application, the thermal insulation sheet includes a woven support layer, an aluminum foil layer arranged on the outside, and an internal thermal insulation cotton layer.

[0017] To implement the above technical solution, the woven support layer is used to ensure the structural strength of the entire insulation sheet, and the insulation cotton layer has a certain thickness to reduce shock and keep warm, thereby preventing the fixed dry ice from hitting the aluminum foil layer and causing damage; and the aluminum foil layer can prevent the dry ice from vaporizing and escaping, while reducing the occurrence of dry ice vaporization caused by heat radiation, thereby ensuring the normal transportation of dry ice.

[0018] As a preferred solution of the present application, a reinforcing braided belt is sewn at the sewing points of two adjacent thermal insulation sheets.

[0019] The above technical solution is implemented to strengthen the sewing parts of the insulation sheets, thereby ensuring the firmness of the connection between the insulation sheets, thereby ensuring the structural strength of the entire flexible insulation bag body.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. Dry ice can be loaded into the flexible insulation bag through the loading port on the top. After loading, the loading port is sealed with a closure to prevent leakage of dry ice. When unloading is required, the handle is simply used to open the loading port at the bottom, allowing the dry ice to fall out under its own gravity, facilitating turnover of loading and unloading. And because the flexible insulation bag is flexible, it can be folded and stacked after loading and unloading, facilitating batch turnover. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The embodiment of the present application discloses a dry ice transport packaging bag. Figure 1The dry ice transport packaging bag includes a flexible insulation bag body 1, which is provided with a loading and unloading port 2 on both the top and bottom of the flexible insulation bag body 1. The loading and unloading port 2 is provided with a closure member 4 for sealing the loading and unloading port 2. A pair of carrying straps 3 are provided on the side walls of the flexible insulation bag body 1. In other words, dry ice can be placed into the flexible insulation bag body 1 from the loading and unloading port 2 at the top of the flexible insulation bag body 1 to complete the loading of dry ice. After loading is completed, the loading and unloading port 2 is sealed with the closure member 4 to prevent leakage of dry ice blocks. When unloading is required, the carrying strap 3 is simply used to open the loading and unloading port 2 at the bottom, allowing the dry ice to fall out under its own gravity, facilitating turnover of loading and unloading. Moreover, because the flexible insulation bag body 1 is flexible, it can be folded and stacked after loading and unloading, facilitating batch turnover.

[0030] The flexible insulation bag 1 includes several insulation sheets 11, which are sewn together. This allows the flexible insulation bag 1 to be folded along the seams, reducing the risk of damage to the sheets 11 from repeated folding. To ensure the secure connection between the insulation sheets 11, a reinforcing braid 12 is sewn between adjacent insulation sheets 11 to reinforce the seams, thereby ensuring a secure connection between the sheets 11 and maintaining the structural strength of the entire flexible insulation bag 1.

[0031] The insulation sheet 11 comprises a woven support layer 111, an external aluminum foil layer 112, and an internal insulation layer 113. The woven support layer 111, aluminum foil layer 112, and insulation layer 113 are laminated using a laminating machine. The woven support layer 111 ensures the structural strength of the entire insulation sheet 11, while the insulation layer 113 has a certain thickness to provide shock absorption and insulation, thereby preventing the impact of fixed dry ice and damaging the aluminum foil layer 112. The aluminum foil layer 112 also prevents the dry ice from vaporizing and escaping, while also reducing the risk of dry ice vaporization caused by heat radiation, thereby ensuring the normal transportation of dry ice.

[0032] The closure 4 includes a number of blocking pieces 41 arranged at equal intervals along the circumference of the material access port 2, and a drawstring 42 is passed between the blocking pieces 41. That is, the drawstring 42 is used to tighten the distance between the blocking pieces 41, thereby achieving the effect of blocking the material access port 2. The blocking pieces 41 are integrally arranged with the flexible insulation bag body 1, and the ends of the blocking pieces 41 are folded inwardly and sewn to form a drawstring ring 43 for the drawstring 42 to pass through. That is, after the drawstring 42 passes through different drawstring rings 43 to connect the blocking pieces 41, the blocking pieces 41 are controlled to retract and open. And because of the integrated arrangement, the structural strength is guaranteed. However, after the drawstring 42 is tightened, there will still be gaps between the blocking pieces 41, resulting in dry ice leakage. Because each blocking piece 41 is located on one side of the interior of the flexible insulation bag body 1, an extension cloth 44 is sewn, and the extension cloths 44 are staggered and stacked, thereby completing the effect of blocking the gaps between the blocking pieces 41. When loading is required, the blocking piece 41 can be pulled out upwards to form a "guide tube" for easy loading of dry ice.

[0033] The implementation principle of a dry ice transport packaging bag in the embodiment of the present application is as follows: dry ice can be put into the flexible insulation bag body 1 from the loading and unloading port 2 on the top of the flexible insulation bag body 1 to complete the filling of dry ice. After the filling is completed, the loading and unloading port 2 is blocked by the sealing member 4 to prevent the leakage of dry ice blocks. When unloading is required, it is only necessary to use the carrying strap 3 to open the loading and unloading port 2 at the bottom, so that the dry ice can all fall under the action of its own gravity, so as to facilitate the turnover of loading and unloading. Moreover, because the entire flexible insulation bag body 1 is flexible, it can be folded and stacked after loading and unloading, so as to facilitate batch turnover.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
