Abstract

The telescopic heat insulating container includes heat insulating cover, sealing gasket, several stages of inner rings capable of being socket jointed, several stages of outer rings capable of being socket jointed, and sealing rings set in the joints between inner rings. Between the inner rings and the outer rings, there are heat insulating air layers and there may be vacuum double-layer structure. During use, the upper heat insulating body and the lower insulating body are separated to maximize the volume. After use, the upper heat insulating body is pressed into the lower insulating body to reduce volume for convenient storage.

Description

technical field

[0001] The invention relates to a telescopic heat preservation container, in particular to a telescopic heat preservation cup or a thermos bottle. Background technique

[0002] In people's daily life, thermal insulation containers are generally used, such as thermos cups and thermos bottles. They are of a great variety and have different structures. It is fixed, and its volume cannot be changed according to people's needs when it is used, and it is especially inconvenient to carry when people go out. People urgently need a kind of adjustable volume size, heat preservation effect is good, the heat preservation container that is easy to carry. Contents of the invention

[0003] The object of the present invention is to provide a telescopic heat preservation container, which has adjustable volume and good heat preservation function.

[0004] The present invention is realized through the following technical solutions:

[0005] The telescopic heat preservatio...
