Problems solved by technology

[0003] Usually, the heat preservation time of the lunch box is not long. After the lunch box is filled with food, it is placed on the table or other surface, and the heat will be conducted from the bottom of the lunch box, causing the temperature of the food in the lunch box to drop rapidly, so it is not easy to keep warm.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0019] Such as Figure 1-Figure 3 The present embodiment provides an insulated lunch box, comprising: an inner container 200 and an outer shell 400 disposed outside the inner container, and a space 700 is provided between the bottom of the inner container 200 and the bottom of the outer shell 400 . The space 700 avoids direct contact between the inner container 200 and the bottom of the outer shell 400, thereby forming a heat insulation barrier, so that the food stored in the inner container 200 can keep warm for a long time.

[0020] A support column 410 is provided at the bottom of the shell 400 , and the bottom of the liner 200 rests on the support column 410 . It is used to support the inner container 200 in the space 700 to prevent the inner container 200 from sinking downward. At the same time, if Figure 4 As shown, the upper edge of...

Abstract

The invention discloses a heat-preserving lunch box. The heat-preserving lunch box comprises a liner and a shell, wherein the shell is arranged outside the liner; an interval space is formed between the bottom of the liner and the bottom of the shell. By forming the interval space between the bottom of the liner and the bottom of the shell, direct contact between the bottom of the liner and the bottom of the shell is avoided, so that a heat-preservation shield is formed, and the heat of food stored in the liner can be preserved for a long time.

Description

technical field [0001] The invention relates to the field of daily necessities, more specifically, to a thermal insulation lunch box. Background technique [0002] The lunch box is an important tableware commonly used in daily life, and it is used for carrying cooked food, and can provide cooked food in a working place or in the field within a certain period of time. [0003] Usually, the heat preservation time of the lunch box is not long. After the lunch box is placed on the tabletop or other object surface after containing food, the heat will be conducted from the bottom of the lunch box, causing the temperature of the food in the lunch box to drop rapidly, thus making it difficult to keep warm. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a thermal insulation lunch box with good thermal insulation effect. [0005] The object of the present invention is achieved by the following technical solutions: a ther...
