Description

Technical Field

[0001] The utility model belongs to the technical field of transportation packaging, and particularly relates to a heat-insulating outer cover for a container liquid bag. Background Art

[0002] A container liquid bag is a new type of flexible packaging container capable of storing and transporting various non-hazardous liquid goods. Since there are no empty container and empty vehicle return freight charges and cleaning costs, and it can effectively avoid cross-contamination of goods, it has more advantages than tank trucks. Therefore, it is widely used in the storage and transportation fields of various non-hazardous liquid goods such as chemicals, food, feed, and agricultural products. During the actual transportation of goods, due to the long transportation distance and drastic temperature changes, the goods in the container are very likely to deteriorate or be damaged, resulting in serious economic losses. To solve this problem, the Chinese utility model patent with the publication number CN205397059U discloses a heat-insulating container liquid bag, which designs the liquid bag into a three-layer structure, and a heat-insulating layer is arranged between the original inner layer of PE film and the outer layer of PP cloth, thereby achieving the effect of constant temperature inside the liquid bag. However, both the bag body and the outer cover of this integrated heat-insulating liquid bag cannot be used alone, thus increasing the use cost and production cost. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a heat-insulating outer cover for a container liquid bag, which can be recycled and add functions such as heat insulation and light insulation to the original container liquid bag.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a heat-insulating cover for a container liquid bag, including a cover body in the shape of a cuboid, which is stitched and connected by a top sheet material, a bottom sheet material, a front sheet material, a rear sheet material, a left sheet material, and a right sheet material. It is characterized in that: a replacement opening is provided at the rear end of the cover body, and a door stopper is detachably connected to the outside of the replacement opening. The top sheet material, the bottom sheet material, the front sheet material, the rear sheet material, the left sheet material, the right sheet material, and the door stopper are all made of aluminum foil bubble film.

[0005] Further, the replacement opening is a square opening located below the rear sheet material. The width of the replacement opening is equivalent to the width of the cover body, and the height is greater than half of the height of the cover body.

[0006] Further, the left side of the door stopper is detachably connected to the rear end of the left sheet material, the right side is detachably connected to the rear end of the right sheet material, the bottom is detachably connected to the rear end of the bottom sheet material, and the top is detachably connected to the bottom of the rear sheet material.

[0007] Further, a window is also provided on the rear sheet material above the door stopper, and a window stopper is detachably connected to the outside of the window. The window stopper is made of aluminum foil bubble film.

[0008] Further, both the door stopper and the window stopper are detachably connected to the cover body through mother-and-son buckles or magic tapes.

[0009] Further, the aluminum foil bubble film is formed by sequentially laminating aluminum foil, bubble film, and aluminum foil.

[0010] Further, the tops of the left sheet and the right sheet both have flanges that extend beyond the top sheet, and multiple suspension straps are sewn on the flanges.

[0011] Further, the multiple suspension straps are evenly distributed along the flange.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Since a replacement opening is provided below the rear sheet of the cover body, and a door stop is detachably connected to the outside of the replacement opening, the liquid bag inside the cover body can be easily replaced after opening the door stop, thereby realizing the recycling of the cover body; each sheet of the cover body and the door stop are made of aluminum foil bubble film. By utilizing the heat insulation, light insulation, air insulation, etc. effects of the aluminum foil bubble film, the temperature change of the material inside the liquid bag is reduced, and the applicable range of the original liquid bag is expanded.

[0014] 2. Since the width of the replacement opening is equivalent to the width of the rear sheet and the height is greater than half of the height of the cover body, the size of the replacement opening is large enough to make the replacement of the liquid bag more convenient and fast, which helps to improve production efficiency.

[0015] 3. Since the left side of the door stop is detachably connected to the rear end of the left sheet, the right side is detachably connected to the rear end of the right sheet, the bottom is detachably connected to the rear end of the bottom sheet, and the top is detachably connected to the bottom of the rear sheet, the door stop is exactly installed at the rear end of the cover body, which not only facilitates the installation or disassembly of the door stop, but also meets the heat preservation function of the door stop for the liquid bag.

[0016] 4. Since a window is also opened on the rear sheet above the door stop, it helps the operator to timely observe the state of the liquid bag inside the cover body through the window.

[0017] 5. Since both the door stop and the window stop are detachably connected to the cover body through mother - and - son buttons or Velcro, it is not only convenient for operation and simple in processing, but also reduces the production cost.

[0018] 6. Since the aluminum foil bubble film is formed by sequentially laminating aluminum foil, bubble film, and aluminum foil, it can not only meet the heat preservation requirements of the liquid bag, but also will not be too thick to affect the capacity of the liquid bag, and has a simple structure and is easy to produce.

[0019] 7. Since the suspension straps are sewn on the flanges of the left sheet and the right sheet, and the flanges are integral with the left sheet or the right sheet, the connection strength between the suspension straps and the cover body is greatly improved, avoiding excessive pulling damage to the cover body during transportation, ensuring the stability of the cover body during transportation, and thus extending the service life of the cover body.

[0020] 8. Since the multiple suspension straps are evenly distributed along the flange, the pulling force of the suspension straps on the flange is more uniform, avoiding local stress causing damage to the cover body, and further extending the service life of the cover body.

[0021] 9. The design of the cover body independent of the liquid bag in the present utility model greatly improves the usage frequency of the original liquid bag, enables it to meet the material transportation needs with heat preservation requirements, and effectively saves transportation costs.
