Description

Technical Field

[0001] The utility model relates to the technical field of glass products and lunch boxes, in particular to a glass lunch box. Background Art

[0002] In today's society, as people's pace of life accelerates, bringing lunch has become a common lifestyle. Glass lunch boxes have become the choice of many consumers due to their unique advantages. As a stable material, glass will not release harmful substances during heating like plastic, ensuring the safety of food. Special types of heat-resistant glass such as high borosilicate glass can withstand sudden temperature changes and are not easy to break, making them suitable for use in microwave ovens and ovens.

[0003] The existing patent (publication number is CN216875338U) and a glass embedded lunch box, this patent uses silicone material to fix the glass panel, the silicone material box cover frame better covers the box body, and the exhaust valve and the exhaust hole are used in combination to release the hot air in the inner cavity of the glass bowl or balance the external air pressure with the internal air pressure of the lunch box, so as to achieve the purpose of convenient exhaust, and solve the problem that when the lunch box is heated, if the exhaust cover is not opened in time, the steam inside the heated lunch box will increase, causing the product to deform, and then the lunch box cannot be used normally. When the internal air pressure of the lunch box is lower than the external atmospheric pressure, the lunch box will shrink and deform, which will also cause damage to the lunch box. The above-mentioned glass lunch box is mainly heated by a microwave oven, which is difficult to heat in the absence of a microwave oven;

[0004] Another existing patent (publication number CN216316124U) and a portable self-heating glass lunch box, this patent can pour a large amount of self-heating powder into the placement box for storage through the cooperation between the placement box, the connecting ring, the connecting plate and the connecting spring. When heating is needed, the insertion rod is pressed to allow an appropriate amount of self-heating powder to be dropped into the self-heating groove along the guidance of the connecting plate. The elastic force of the connecting spring is used to reset the connecting plate and seal the placement box again. There is no need to use traditional means to repeatedly take out the self-heating powder to wrap hot meals, which is conducive to the repeated use of the self-heating glass lunch box. It is correspondingly difficult for people who lack microwave ovens to use self-heating powder. At the same time, the complex structure will increase the manufacturing cost, and the method of using the self-heating bag is too cumbersome.

[0005] Therefore, we propose a glass lunch box, which is conducive to heating the glass lunch box with hot water, and can also keep the temperature of the glass lunch box from losing quickly by adding hot water, and at the same time protect the glass lunch box. Utility Model Content
