The utility model provides a corrugated case with a preservation function, which is improved in pressure strength, realizes precooling, sterilization and other processing and is ventilated.

Description

The corrugated case that has preservation device

Technical field

The utility model relates to the corrugated case that article packing is used, and particularly relates to a kind of corrugated case that has preservation device.

Background technology

Corrugated case of the prior art has a wide range of applications in the various packings of product, particularly the more too busy to get away corrugated case of the packing of fruit and vegetable.The structure of traditional corrugated box is common by people, its function only limits to packing, and can't satisfy the specific (special) requirements that fruit and vegetable is packed, and in fact, fruits and vegetables has higher requirement to packing in storage, transportation and sales process, for preventing extruding, rot, go bad, should take to give cold, sterilization, sterilize and make measures such as packing material inner air flow, particularly all the more so for the fruit and vegetable of long-distance transport.

Summary of the invention

The utility model mainly is to solve the deficiencies in the prior art, and a kind of compressive strength that both increased is provided, processing such as that fork can give is cold, sterilization, and the corrugated case that has fresh-keeping function that maintains the circulation of air.Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:

A kind of corrugated case that has preservation device, comprise casing, by the side of two relative sides wherein a liner plate is housed respectively in the casing, respectively there is a flanging at the two ends, the left and right sides of each liner plate, four interior angles of this flanging and casing form four gas passages, and are covered with pore on the flanged plate face; The casing inner bottom part is equipped with backing plate, and the edge of backing plate is provided with downward flanging, makes to form gas passage between backing plate and box bottom, also is covered with pore on the backing plate plate face; Wall box is provided with the cold air and the sterilizing gas that are connected with gas passage and goes into mouth and outlet, in the gas access and the exit check valve is housed.

The utility model has effectively overcome the problem that existing corrugated case does not have fresh-keeping function, owing in corrugated case, be provided with liner plate and the backing plate that has flanging and pore, and formed gas passage between they and the casing, and be provided with the entrance and exit that to import cold air and sterilizing gas, thereby make fruits and vegetables in packing, store, in transportation and the sales process, particularly can give cold in the long-distance transport process, sterilizing, Preservation Treatment such as ventilation, rotten to guarantee the fruits and vegetables imputrescibility, liner plate and backing plate have also increased the compressive strength of casing simultaneously, can prevent effectively that fruits and vegetables is squeezed.The utility model also has simple in structure, implements the characteristics that are easy to.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: as shown in Figure 1 and Figure 2, comprise a square casing 10 of making by fluting board, its structure is identical with existing corrugated case, main points of the present utility model are, a liner plate 20 respectively is equipped with in keep left in casing right two sides or two sides, front and back, its structure as shown in Figure 3, respectively there is a vertical flanging 21 that is folded to forequarter at the two ends, the left and right sides of each liner plate, four interior angles of this flanging and casing form the gas passage 30 of four leg-of-mutton above-below directions, and be covered with pore 211 on the flanged plate face, the gas in the gas passage can be imported in the casing.The casing inner bottom part is equipped with backing plate 40, its structure as shown in Figure 4, the edge of backing plate is provided with downward flanging, this flanging is converted into square, to increase compressive strength, and flanging makes and also is covered with pore 41 on the backing plate plate face by the gas passage 50 that forms horizontal direction between backing plate and box bottom that the gas passage up and down at four jiaos of places of this horizontal gas passage and casing constitutes the gas circulation channel for gas communication in the case jointly.For the fruits and vegetables that is loaded in the casing is carried out Preservation Treatment, on near casing top sidewall, be provided with cold air and the sterilizing gas inlet 11 that is connected with gas passage 30,50, relative position place in its diagonal line one side is provided with gas vent 12, in the gas access 11 and export 12 places the check valve that is similar to bicycle valve core is housed, make gas unidirectionally enter or to discharge.When carrying out Preservation Treatment, available refrigerating compressor with cold air and ozonization gas in gas access input casing, PROCESS FOR TREATMENT such as, gasflow clean-up cold, sterilization to give, make shortage give on a large scale cold, clean, the medium-sized and small enterprises of sterilization can adopt packing chest of the present utility model to realize Preservation Treatment.

Claims (1)

1. corrugated case that has preservation device, comprise casing (10), it is characterized in that: by the side of two relative sides wherein a liner plate (20) is housed respectively in the casing, respectively there is a flanging (21) at the two ends, the left and right sides of each liner plate, four interior angles of this flanging and casing form four gas passages (30), and are covered with pore (211) on the flanged plate face; The casing inner bottom part is equipped with backing plate (40), and the edge of backing plate is provided with downward flanging, makes to form gas passage (50) between backing plate and box bottom, also is covered with pore (41) on the backing plate plate face; Wall box is provided with cold air and sterilizing gas inlet (11) and the outlet (12) that is connected with gas passage (30), (50), and (11) and outlet (12) locate to be equipped with check valve in the gas access.
