TECHNICAL FIELD

[0001] The utility model relates to the field of preservation box, more specifically, it relates to a preservation box with low-emission food contact level sealing cover. BACKGROUND

[0002] The preservation box, as a powerful assistant of modern home life, plays an important role in food storage. It is usually made of food-grade plastic, glass or ceramic materials, which effectively prevents food from being mixed with other foods, losing moisture and being invaded by external air and bacteria by sealing the food.

[0003] However, most of the preservation boxes on the market currently rely on a single sealing ring on the cover to achieve sealing. Over time, gas is generated inside the food, causing an increase in pressure. The sealing performance of a single sealing ring is severely tested when dealing with such internal pressure, and gas leakage may occur, causing food to mix with other foods and accelerate spoilage.

[0004] Therefore, in order to solve the above technical problems, the present application provides a preservation box with a low-emission food contact level sealing cover. UTILITY MODEL CONTENT

[0007] Preferably, an elastic fixing assembly is installed between the box body and the cover body, so that they can be firmly connected.

[0008] Preferably, the elastic fixing assembly comprises connecting groove seats fixed on both sides of the outer side wall of the box body, and plug blocks connected to both sides of the outer side wall of the box body through connecting plates, the surface of the connecting groove seat is provided with a circular through groove communicating with the inside thereof, the surface of the plug block is provided with a circular recess, a plurality of springs are arranged in a circular array in the inside of the circular recess, and the head of the spring is fixedly connected with a cylindrical block capable of penetrating through the circular through groove.

[0009] Preferably, the inner center part of the circular recess is connected to the cylindrical block through a telescopic rod, and the telescopic rod is used to maintain the linear movement of the cylindrical block relative to the circular recess.

[0010] Preferably, a handle is mounted on the outer wall of the box body, and the handle facilitates the staff to hold the preservation box.

[0011] Preferably, the bottom end of the box body is covered with a rubber pad, and the bottom of the rubber pad is provided with friction lines, which enhance the friction force between the preservation box and the placement plane, so that the preservation box can be stably placed, and the risk of damage caused by accidental sliding is reduced.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model discloses a top of box body is pressed against the elastomer on the inner top wall of cover body, and the four peripheral parts of the opening are in contact with the elastomer on the inner side wall of cover body, the elastomer is extruded, thereby adhering to the box body, filling the tiny gap, so that the sealed box is more completely sealed, although the elastomer on the other parts of the inner top wall of cover body is not in contact with the box body, but when the gas produced in the cover body makes the gas pressure in the preservation box higher, the elasticity of the elastomer will be deformed, thereby forming an expanded space, so as to reduce the gas pressure, thereby reducing the influence of the gas pressure on the elastomer of the sealing part, and the V-shaped structure of the elastomer can realize the deep sealing between the cover body and the box body, and the sealing effect is better, so that the problem of poor sealing effect of the single sealing ring in the background art is solved.
