Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging and transportation, in particular to a high-efficiency heat-insulating transportation carton. Background Art
[0002] With the rapid development of e-commerce, especially the growing demand for temperature-sensitive goods such as fresh food and medicine, how to ensure that these goods maintain their quality during transportation has become an urgent problem to be solved. Traditional insulated transportation solutions often have the following problems:
[0003] Insufficient thermal insulation performance: Many existing thermal insulation boxes use simple foam materials as the thermal insulation layer. Although the cost is low, it is difficult to maintain a stable low-temperature environment inside during long-term transportation or extreme weather conditions.
[0004] Fragile structure: Some thermal insulation boxes sacrifice durability in pursuit of lightweight design, which makes them easily damaged during the logistics process, affecting the insulation effect and the safety of the items.
[0005] High cost: Some advanced thermal insulation boxes use complex multi-layer composite materials and advanced temperature control systems. Although they have good thermal insulation effects, they are expensive and not suitable for large-scale promotion and application.
[0006] Non-recyclable: Many disposable insulation packaging materials not only increase the burden on consumers, but also put great pressure on the environment and do not meet the requirements of sustainable development. Utility Model Content
[0007] In view of this, in view of the existence of the above problems, it is particularly necessary to develop a new type of transport carton that can ensure good thermal insulation effect and is economical and environmentally friendly.
[0008] The utility model discloses a highly efficient heat-insulating shipping carton, comprising a base box and a sleeve box. The sleeve box is buckled onto the base box. The panels of the base box and sleeve box are, from the inside to the outside, a waterproof layer, corrugated paper, a heat-insulating buffer layer, aluminum foil, corrugated paper, and a waterproof layer. This design not only allows for adjustable box volume, but also utilizes the overlapping areas of the base box and sleeve box to enhance the heat-insulating effect and the overall structural strength.
[0009] To further describe the above solution, the waterproof layer is made of waterproof kraft paper or polypropylene material, which has good wear resistance and waterproofness and can effectively resist the influence of the external environment.
[0010] More preferably, the thermal insulation buffer layer is made of pearl cotton or polyethylene foam. These two materials are low in cost, have excellent thermal insulation properties, and can keep the temperature in the box stable for a long time.
[0011] According to one embodiment of the present application, the thermal insulation buffer layer is polyethylene foam, the waterproof layer is waterproof kraft paper, and the waterproof kraft paper, corrugated paper, polyethylene foam, aluminum foil, corrugated paper, and waterproof kraft paper are pressed together in sequence to form a whole, and corresponding creases are pressed.
[0012] Furthermore, the inner bottom of the bottom box and the inner top of the cover box are both provided with polyethylene foam boards, which further improve the cushioning performance and heat preservation effect.
[0013] Furthermore, the thickness of the thermal insulation buffer layer is between 20 mm and 50 mm.
[0014] Optionally, the top of the box is further provided with an openable cover, providing different ways of opening the box.
[0015] Compared with the existing technology, the high-efficiency heat-insulating transport carton proposed by the utility model has the following significant advantages:
[0016] Excellent thermal insulation performance: By using high-density polyethylene foam as the main insulation material, combined with aluminum foil to reflect radiant heat inside and outside the box, the thermal insulation effect is further enhanced.
[0017] Sturdy and durable design: The outer layer of waterproof and wear-resistant material not only enhances the overall strength of the carton, but also extends its service life, making it more suitable for long-distance transportation and repeated use; the box board is pressed and synthesized, with strong impact resistance and bending force, and the nested installation of the bottom box and the outer box further improves the pressure resistance.
[0018] Economical and affordable: Compared with other high-end insulation products on the market, this utility model has lower cost and higher cost performance, which is very suitable for small and medium-sized enterprises and individual consumers.
[0019] Green environmental protection concept: all are made of environmentally friendly and recyclable materials.
[0020] In summary, this highly efficient insulated shipping carton not only solves many defects of traditional insulated boxes, but also provides users with a more reliable, convenient and environmentally friendly cold chain logistics solution. BRIEF DESCRIPTION OF THE DRAWINGS
