AI Technical Summary

Technical Problem

When existing ceramics are in close contact with the glass covering, they are prone to breakage and discoloration due to differences in the thermal expansion rates of the materials and external thermal damage, and are directly affected by external forces and heat.

Method used

Design a container with outer and inner container sections made of glass, in which ceramics can move within the gaps. The joints are formed by heating and welding to avoid fixed contact. The low expansion rate and thermal insulation properties of borosilicate glass are used to reduce thermal stress.

Benefits of technology

Ceramic ware is unaffected by differences in thermal expansion rates and direct heat or external force damage, retains its unique design, and has good thermal insulation and heat preservation properties.

Abstract

Provided is a container that is resistant to external force and heat even though ceramic is used. A cup (1A) as the container includes an outer container portion (2) having light transmissivity, an inner container portion (3) disposed apart by a gap inside the outer container portion (2) and joined to the outer container portion (2), and a ceramic (5) movably disposed in an internal space (4) formed by the gap between the outer container portion (2) and the inner container portion (3).
