Description

Thermos cup

This creation is about a heat preservation cup, especially a heat insulation cup which can be easily disassembled.

In the process of outdoor activities, the temperature of beverages or water is mostly stored in a thermos cup. For the purpose of heat insulation, the cup body of a general insulated cup is composed of two sets of inner and outer container sets.

A common assembly method is to apply an adhesive such as glue on the outer wall of the inner liner of the insulation cup, and leave the inner liner for a period of time. When the glue is air-dried, the tube-shaped outer sleeve covers the inner liner of the insulation cup upward, so that the adhesive on the outer wall of the inner liner adheres to the outer sleeve and the inner liner to fix the outer sleeve and the inner liner to each other.

However, this assembly method requires the adhesive to be air-dried before it can be assembled, making the overall assembly process very time-consuming. In addition, after long-term use of the insulation cup, the glue is easily aged and the viscosity is weakened, so that the inner liner is loosened and dropped out of the outer sleeve. In addition, if the user accidentally breaks the liner, the repairman needs to remove all the liner fragments remaining on the outer sleeve before replacing the liner, which is very inconvenient for the repair and maintenance of the insulation cup.

Therefore, how to propose a thermal insulation cup that can solve the above problems is one of the problems that the industry is eager to invest in research and development resources.

In view of this, one of the purposes of this creation is to propose an insulation cup that can be easily disassembled without the need for an adhesive.
