Abstract
The utility model relates to a sealed lunch box. The structure of the sealed lunch box is that a sealing ring is arranged between the box body and the cover of the lunch box; both sides of the lunch box body are provided with a pressing device for pressing the cover of the lunch box, so that the sealing ring is clamped tightly between the box cover and the box body to reach the aim of seal; therefore, the problem of the soup leakage of the lunch box is effectively solved.
Description
The utility model belongs to household implements.
Lunch box is indispensable commodity in China people daily life.But lunch box exists a very big shortcoming always for a long time, leaks soup when carrying exactly easily, and this has brought very big worry and inconvenience to people.
The purpose of this utility model is to solve lunch box to leak this problem of soup.
The purpose of this utility model realizes by following structures.As shown in drawings, a sealing ring 2 is arranged between cover of the lunch box and box body, form with a tension linkage that links to each other with clinching 4 by a clinching 3 that can ride on the cover of the lunch box by hold down gag 1 hold down gag that compresses lid in the both sides of box body.Effect lower casing and box body at hold down gag clamp sealing ring, thereby make the lunch box sealing.Have a bit of 5 differently with sealing ring on sealing ring, the top in its cross section is less than the top in sealing ring cross section.This section is as safety valve.The cross section of this section can be an inverted T-shaped, also can be L shaped, can also be triangle.When lunch box is heated internal pressure when excessive, the top distortion of safety valve, the mouth that makes breakthroughs is discharged pressure.When the lunch box internal pressure reduced to a certain degree, the top of safety valve relied on elasticity to set back, and reseals.This safety valve plays the effect of control lunch box internal pressure.Can also the fixed fold handle in the both sides of lunch box, can be during the heat-obtaining lunch box with the handle pull-up, not only non-scald on hand but also steady.
Accompanying drawing 1 is the front view of sealing lunch box;
Accompanying drawing 2 is that accompanying drawing 1A is to cutaway view;
Accompanying drawing 3 is the safety valve schematic diagram;
Accompanying drawing 4 is the safety valve schematic cross-section.
In embodiment of the present utility model, hold down gag is to be made by rubber with the elasticity clinching sealing ring that stainless steel wire is made, and the cross section of safety valve is an inverted T-shaped, long 12 millimeters, be arranged on that the cover of the lunch box upper punch becomes groove and has some oblique angles on the angle, sealing ring is embedded in the groove.
