Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal insulation filling technology, and more specifically, it relates to a thermal insulation filling structure for packaging cartons. Background Technology
[0002] Corrugated cardboard boxes have become the mainstream in the packaging industry. When packaging goods, filler is usually placed inside the cardboard box to protect them from damage during transportation. In current technology, when packaging multiple items, each item needs to be individually wrapped with filler before being placed into the cardboard box. This process is complex and reduces packaging efficiency. Secondly, current cardboard boxes have poor insulation properties. When transporting frozen foods, the frozen foods easily thaw or spoil, making long-distance transport impossible. Utility Model Content

[0029] Please see Figures 1-6 A thermal insulation filling structure for packaging cartons includes a filling box 1. The upper end of the filling box 1 is movably provided with a cover 2. Multiple adjusting components are fixedly installed inside the filling box 1. Each adjusting component includes a partition strip 3. The partition strip 3 is fixedly installed inside the filling box 1. There are multiple partition strips 3. Each partition strip 3 is provided with an airbag 4. There are multiple airbags 4. A through hole 5 is provided between two adjacent airbags 4. One of the airbags 4 is connected to an inflation tube 6. The inflation tube 6 is a flexible tube and is provided with a valve body 7.
[0030] In this embodiment, multiple items to be packaged are placed on both sides of multiple dividers 3 inside the filling box 1. After the items are placed, the valve body 7 is opened, and multiple airbags 4 are inflated through the inflation tube 6. The multiple airbags 4 are connected through the through hole 5, so that all multiple airbags 4 are inflated, thereby fixing and protecting multiple items according to the size of the items placed. After inflation is completed, the valve body 7 is closed, and the cover 2 is placed on the top of the filling box 1, so that multiple items can be filled at the same time.
[0031] Please see Figures 1-6 As one embodiment for fixing and sealing the cover 2: a protruding ring 8 is fixedly provided at the lower end of the cover 2, a sealing ring 9 is fixedly provided at the lower end of the protruding ring 8, a groove 10 that mates with the protruding ring 8 is provided on the filling box 1, a fixing strip 11 is fixedly provided on the outer side of the cover 2, the number of fixing strips 11 is four, a first female hook and loop fastener 12 is fixedly provided on each fixing strip 11, a fixing ring 13 is fixedly provided on the filling box 1, and four first female hook and loop fasteners 14 that mate with the first female hook and loop fastener 12 are fixedly provided on the fixing ring 13.
[0032] Specifically, the cover 2 is placed on the upper end of the filling box 1, so that the convex ring 8 moves into the groove 10. The sealing ring 9 seals the convex ring 8 and the groove 10. The fixing strip 11 and the fixing ring 13 are made of non-woven fabric. The fixing strip 11 drives the first female hook and loop fastener 12 to move onto the first male hook and loop fastener 14, so that the first female hook and loop fastener and the first male hook and loop fastener 14 are attached to each other, thereby fixing the cover 2 to the upper end of the filling box 1.
[0033] Please see Figures 1-6 As one embodiment of placing ice packs: a mesh bag 15 is fixedly provided inside the cover 2, a second female hook and loop fastener 16 is fixedly provided on the mesh bag 15, a support strip 17 is fixedly provided on the cover 2, and a second female hook and loop fastener 18 that cooperates with the second female hook and loop fastener 16 is fixedly provided on the support strip 17.
[0034] Specifically, pulling the mesh bag 15 causes the second female hook and loop fastener 16 to separate from the second female hook and loop fastener 18, thus opening the mesh bag 15. An ice pack is then placed inside the mesh bag 15, and the second female hook and loop fastener 16 is attached to the second female hook and loop fastener 18, thus securing the ice pack inside the mesh bag 15. The ice pack inside the mesh bag 15 can be used to cool the items inside the filling box 1. The filling box 1 and the lid 2 are made of foam material, which can insulate the internal items.
[0035] In summary, when using the overall equipment:
[0036] When multiple items need to be quickly filled and packaged, place the items to be packaged on both sides of the multiple dividers 3 inside the filling box 1. After the items are placed, open the valve body 7 and inflate the multiple airbags 4 through the inflation tube 6. The multiple airbags 4 are connected through the through hole 5, so that all the airbags 4 are inflated. This fixes and protects the multiple items according to their size. After inflation, close the valve body 7 and put the cover 2 on the top of the filling box 1 to fill the multiple items at the same time.
[0037] When it is necessary to fix the lid 2 to the filling box 1, place the lid 2 on the top of the filling box 1, causing the convex ring 8 to move into the groove 10. The sealing ring 9 seals the convex ring 8 and the groove 10. The fixing strip 11 and the fixing ring 13 are made of non-woven fabric. The fixing strip 11 moves the first female hook and loop fastener 12 onto the first female hook and loop fastener 14, so that the first female hook and loop fastener and the first female hook and loop fastener 14 are attached, thereby fixing the lid 2 to the top of the filling box 1. Then, the filling box 1, along with the item and the lid 2, is placed into the packaging carton. The size of the filling box 1 is just enough to fill the inside of the packaging carton. The packaging carton is then closed and sealed to complete the packaging.
[0038] When it is necessary to cool the items inside the box, before the lid 2 is fixed, pull the mesh bag 15. This causes the second female hook and loop fastener 16 to separate from the second female hook and loop fastener 18, thus opening the mesh bag 15. Place the ice pack inside the mesh bag 15, and then attach the second female hook and loop fastener 16 to the second female hook and loop fastener 18, thus securing the ice pack inside the mesh bag 15. The ice pack inside the mesh bag 15 can be used to cool the items inside the filling box 1. The filling box 1 and the lid 2 are made of foam material, which can keep the internal items warm.
[0039] Of all the solutions mentioned above, those involving connections between two components can be selected based on actual conditions, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods. These will not be elaborated here. For all fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
