Problems solved by technology
[0006] The purpose of the present invention is to provide a fresh cold chain circulation packaging box to solve the problem that the cost of the general freight car proposed in the above-mentioned background technology is low, but it cannot be kept warm. One-time use cannot protect the goods well, resulting in increased costs and greater losses. At the same time, the foam box keeps fresh, but it is easy to cause environmental pollution.

Embodiment 1
[0048] see Figure 1-7 , the present invention provides a technical solution: a fresh cold chain cycle packaging box, including a carton body layer 1, a hollowed-out handle port 2, a bottom plate combination layer 3, an upper sealing cardboard 4, a connecting layer 5, a buckle layer 6, a conflicting Limiting cardboard layer 7, hollowed-out through hole 8, locking hole 9, outer limit cardboard layer 10, guide groove 11, corrugated raw cardboard 12, reserved cavity 13, outer coating 14, adhesive layer 15, convex Layer 16 and inner fresh-keeping layer 17 are formed.
[0049] The outer end of the carton body layer 1 is provided with a hollow handle opening 2 for easy lifting, and the lower end of the carton body layer 1 is cut with a combined and sealed bottom plate combination layer 3, and the upper end of the carton body layer 1 is cut with an upper sealing cardboard 4 ;
[0050] The upper end of the upper sealing cardboard 4 is cut with a connecting layer 5 to form a folded s...
Embodiment 2
[0060] refer to Figure 8-14 As shown, on the basis of Example 1, the applicant further proposed an improvement of the rigid support structure in order to seek a better carton support effect.
[0061] Specifically, the carton body layer is divided into a front body layer 101 and a rear body layer 102, specifically two side boxes with larger areas, and at least A set of front rigid supports and rear rigid supports; the front rigid supports and the rear rigid supports correspond to each other after the box is combined;
[0062] Both the front rigid support and the rear rigid support include two rigid support plates 18, an accommodating groove 19 arranged on the carton body layer 1 and matched with each rigid support plate 18, and an accommodating groove 19 arranged in the accommodating groove 19. The arched ear pressing grooves 20 on both sides and the elastic pressing ears 21 that can be elastically matched with the arched ear pressing grooves 20 and integrally formed at the e...

Abstract
The invention discloses a fresh food cold chain circulation packaging box. The fresh food cold chain circulation packaging box comprises a carton body layer, a connecting layer, hollowed-out through holes and clamping holes, hollowed-out hand lifting openings facilitating lifting are formed in the outer end of the carton body layer, a combined and sealed bottom plate combination layer is cut at the lower end of the carton body layer, and meanwhile an upper sealing paperboard is cut at the upper end of the carton body layer; and the connecting layer is cut at the upper end of the upper sealing paperboard and forms a folding structure, the hollow through holes are formed in the outer side of the upper sealing paperboard, and the clamping holes corresponding to the connecting layer are formed in the outer side of the carton body layer. According to the fresh cold chain circulation packaging box, corrugated base paper is connected into countless hollow three-dimensional regular hexagons through a glue bonding method to form an integral stress part, surface paper is bonded to the two faces of the integral stress part to form a novel environment-friendly and energy-saving material of a sandwich structure, honeycomb paperboards are good in load bearing, inner aluminum foil can keep fresh, preserve heat and prevent moisture, and an outer film is waterproof; and printing is convenient, environmental friendliness is achieved.
Description
technical field [0001] The invention relates to the technical field of fresh food cold chain, in particular to a fresh food cold chain circulation packaging box. Background technique [0002] IoT smart packaging is currently mainly used in food and beverage, logistics, daily chemical products, pharmaceuticals and other fields, among which the food and beverage field accounts for 30% of the market share, ranking first; followed by the logistics field, the application market share is about 20%. %; the market shares of daily chemical products and pharmaceuticals are both 10%. The demand for IoT smart packaging in the fresh food market is high, but the market share is very low; [0003] Various damage phenomena in the express delivery process, such as fresh fruits, have brought immeasurable losses to farmers. Generally, cold chain vehicles are used to transport fresh products, but the cost is high, and there are special requirements, and the general The cost of the freight car...
