The quality of the invention is different from all kinds of preservation boxes in that: the interior of the box body can be decompressed by pumping air outwards through the air pumping plug 13, namely, the air pressure in the box body is lower than the air pressure outside the box body through pumping air; the box is pressurized by injecting gas into the box through the inflation plug 3, namely, the air pressure in the box is higher than the air pressure outside the box by injecting fresh-keeping gas into the box. For this purpose, the box body must be provided with a rubber plug which can be conveniently evacuated and a rubber plug which can be conveniently inflated at any time, and the purpose of installing the evacuation plug 13 and the inflation plug 3 is that.
The rubber plug mounting hole 18 is arranged on the box body and is matched with the inflation plug 3 and the air exhaust plug 13, the diameter of the hole is 1-4 mm smaller than the diameter of the bottom of the annular groove on the inflation plug 3 and the air exhaust plug 13, and the small hole ends of the inflation plug 3 and the air exhaust plug are pressed into the mounting hole 18 by brute force. For the convenience of installation, the diameter of the mounting hole 18 at the outer end of the box is 1.5 to 3mm larger than that at the inner end of the box, and in order to prevent the hole from extruding the bottom of the annular grooves of the inflation plug 3 and the suction plug 13 for a long time to cause the rubber stopper to lose elasticity, the depth (i.e. the wall thickness) of the hole is not less than 1.5 mm, and is generally 2 to 8 mm. In order to prevent the thickness of the whole box body from being increased due to the thickness of the hole, thereby wasting raw materials, the problem can be solved by adopting a method of singly thickening the parts where the inflation plug 3 and the air extraction plug 13 are arranged. For example, if the overall wall thickness of the box body is 1 mm, the wall thickness of the region of the mounting hole 18 which is 5 to 10 mm larger than the sphere diameter of the inflation plug 3 and the suction plug 13 is designed to be 2 to 3mm, and gradually changed, as shown in fig. 6. Therefore, the thickness requirement of the mounting hole is met, the box is attractive and durable, and the protruded part can be arranged outside the box body, can be arranged inside the box body and can be taken into consideration both inside and outside.
The other quality difference of the preservation box and the existing preservation box is as follows: the box body 1 is provided with 4-24 holes with the diameter of 20-200 mm, namely an air pressure display window 8, which is called a display window 8 for short. The window is covered with a layer of 0.2 to 1.2 mm thick air pressure display film 9 made of soft rubber film, the display film 9 is short, the film is pressed with a fixed pressing plate 10 with the inner hole diameter same as the display window, the fixed pressing plate 10 is tightly fixed on the box body wall through a fixing screw 11. In order to prevent the fixing screw 11 from loosening and falling off, a fixing retainer 12 is additionally arranged on the inner side of the box body wall, and the thickness and the inner diameter of the fixing retainer 12 are the same as those of the fixing pressure plate 10. The air pressure display window 8 may be round, square, oval, or other shapes, and functions as: when the air pressure in the box is lower than the air pressure outside the box, the display film 9 can be sunken in the box, the lower the air pressure in the box is, the larger the sunken amplitude is, and the sunken condition can help the air extractor to extrude the air in the box besides displaying the air pressure in the box, so that the pressure of the air pressure outside the box on the box wall is reduced. When gas is injected into the box and the pressure of the injected gas exceeds the pressure outside the box, the display membrane 9 protrudes outward from the box, and the larger the protruding range is, the higher the gas pressure inside the box is. The display membrane 9 protruding outward of the case can help the inflator relieve the pressure of the gas pressure inside the case against the case wall in addition to displaying the gas pressure inside the case.
4 to 24 display windows 8 can be distributed on the front, rear, left and right walls of the box body 1, or 1 to 2 display windows can be arranged on the box cover 2.
In order to facilitate carrying of the preservation box, the hand grips 15 can be arranged on any two opposite wall walls of the box body 1, and the hand grip 15 on each wall can be one or a pair, depending on convenience and attractiveness. When the content in the fresh-keeping box is less than 3 kilograms, the hand grip 15 is not needed.
