Technical Field
The utility model relates to a lunch-box technical field specifically is a sealed lid of lunch-box.
Background
The lunch box is a box specially used for containing food and is also calledLunch boxThe box is mostly made of aluminum, stainless steel and plastic; the common lunch box consists of a box body and a cover body, generally speaking, most of the traditional lunch box cover bodies are fixed in a buckling mode, and the lunch box is made of materialsThe tension of the body, the elasticity of the material can be reduced after the material is used for many times, so that the connection mode is not tight after being used for a long time; in addition, the existing cover body has many vent hole structures, but in many cases, perfect combination of operation and air tightness is difficult to achieve.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sealed lid of lunch-box to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a closure for a lunchbox comprising: lid, frame, silica gel strip, sealing plug, the lid be transparent material's square flat board, and open on the lid and have the air vent, the frame rigid coupling around the lid, silica gel strip rigid coupling in the inboard of frame, silica gel strip parcel box body upper port when using, the sealing plug setting on the air vent of lid, the sealing plug comprises gasket, spliced pole, stopper, support ball, the gasket be the disc, the gasket covers the air vent upper surface at the lid, the central point of spliced pole up end connection terminal surface under the gasket put, the spliced pole passes the air vent of lid, the stopper establish the end at the spliced pole, the stopper is located the lower terminal surface of lid, the support ball be the hemisphere, support ball rigid coupling under the gasket the inboard of terminal surface around.
Furthermore, the sealing plug is of an integrated structure formed by injection molding of rubber materials.
Furthermore, a cylindrical groove is formed in the upper surface of the cover body, and the sealing plug is located inside the cylindrical groove.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the structure is simple, and the production is convenient;
2. the operation is easy and the use is convenient;
3. the sealing effect is good, and the air tightness is good.
The utility model has the advantages of simple structure, easy operation, good use effect, etc.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 and 2, the present invention provides a sealing cover for a lunch box, including: a cover body 1, a frame 2, a silica gel strip 3 and a sealing plug 4, wherein the cover body 1 is a square flat plate made of transparent material, the cover body 1 is provided with vent holes, the frame 2 is fixedly connected around the cover body 1, the silica gel strip 3 is fixedly connected at the inner side of the frame 2, the silica gel strip 3 wraps the upper end opening of the box body when in use, the sealing plug 4 is arranged on the vent hole of the cover body 1, the sealing plug 4 is composed of a sealing sheet 5, a connecting column 6, a limiting block 7 and a supporting ball 8, the sealing piece 5 is in a circular sheet shape, the sealing piece 5 covers the upper surface of the vent hole of the cover body 1, the upper end surface of the connecting column 6 is connected with the central position of the lower end surface of the sealing piece 5, the connecting column 6 penetrates through the vent hole of the cover body 1, the limiting block 7 is arranged at the tail end of the connecting column 6, the limiting block 7 is positioned on the lower end surface of the cover body 1, the supporting balls 8 are hemispherical, and the supporting balls 8 are fixedly connected to the periphery of the inner side of the lower end face of the sealing piece 5.
Furthermore, the sealing plug 4 is an integral structure formed by injection molding of a rubber material.
Furthermore, a cylindrical groove is formed on the upper surface of the cover body 1, and the sealing plug 4 is located inside the cylindrical groove.
The working principle is as follows: the utility model provides a sealing cover body of a lunch box, firstly, the utility model changes the traditional buckle connection mode, utilizes the air in the lunch box to become cold and form negative pressure, adopts the silica gel strip 3 to seal, utilizes the air pressure to fix the cover body 1 on the box body, at the moment, the sealing plug 4 can be tightly adsorbed on the cover body 1, when needing to open the lunch box, only the central position of the sealing sheet 5 needs to be pressed, because of the function of the supporting ball 8, the outside of the sealing sheet 5 can be tilted at the moment, the outside air can pass through the gap of the supporting ball 8 at the moment, and enters the inside of the lunch box through the air vent, thereby balancing the air pressure in the lunch box, and opening the cover body 1 lightly; and the sealing plug 4 is positioned in the cylindrical groove, so that the lunch box can be effectively prevented from being opened due to mistaken collision.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
