Description

Technical Field

[0001] The utility model relates to the technical field of fresh-keeping boxes, in particular to a snap-fit ​​fresh-keeping box cover. Background Art

[0002] Fresh-keeping boxes are generally made of transparent or translucent materials, especially heat-resistant glass fresh-keeping boxes are made of high borosilicate glass. The glass is transparent, so people can easily confirm the contents of the box without having to open the box when using it. Different shapes can store different things, which is more convenient to use. In addition to the common square, rectangular and round shapes, there are also sets designed for picnics, which make life simpler and more convenient. The fresh-keeping box lid is an important part of the fresh-keeping box, but the existing fresh-keeping box lid mostly adopts a snap-on structure design. After long-term repeated use, the snap-on structure is easily broken, making the fresh-keeping box unable to be sealed, thereby losing the fresh-keeping function. At the same time, the snap-on structure cannot be replaced accordingly after being damaged, and the original fresh-keeping box lid can only be discarded, thereby wasting resources. In addition, the sealing ring of the fresh-keeping box lid is not firmly fixed and is prone to accidental falling, making the components of the fresh-keeping box lid easily lost. In addition, the vent sealing structure of the existing fresh-keeping box lid mostly adopts a flip-top structure. When the food in the fresh-keeping box needs to be sealed and preserved, the flip-top sealing lid is easily accidentally opened, resulting in failure of the seal of the fresh-keeping box.

When the food storage box abuts against the main sealing ring 8, the fastening layer 3 will also abut against the food storage box at the same time. During the deformation of the fastening layer 3, the adsorption holes on the surface of the fastening layer 3 will adsorb and fix the surface of the protruding outer edge of the food storage box, thereby completing the fixed connection between the food storage box and the lid of the food storage box. It can also effectively reduce the probability of accidental release of the two sets of fixing structures. When the snap plate 2 is damaged, the fitting columns 16 on both sides of the upper end of the snap plate 2 are squeezed at the same time, so that The engaging column 16 can be moved into the corresponding auxiliary buffer groove 17, so that the connection between the locking plate 2 and the movable seat 11 can be smoothly released, and the efficiency of loading, unloading and replacing the locking plate 2 is improved. When the air vent 6 of the fresh-keeping box cover needs to be closed later, the movable block 4 is pushed to move through the auxiliary groove.
