US 6,119,889 A · Transparent insulated container and manufacturing method therefor

Abstract

A transparent insulated container is provided which has a simple structure, which has superior temperature maintaining properties, and is transparent such that the contents housed within the insulated container can be visually checked from the sides. The transparent insulated container has a double-walled structure in which inner and outer containers formed from a transparent material such as glass or synthetic resin, are arranged so that a space is formed therebetween, and are made into a single body by joining the rims of their respective mouths and. A thermal radiation preventing layer through which visible rays can pass is formed on at least one of outer surface of inner container and inner surface of outer container which are on opposite sides of and face onto the space.

Dependent claims

A transparent insulated container comprising a double-walled structure formed by an inner container, formed from a transparent material such as glass or synthetic resin, arranged within an outer container, formed from a transparent material such as glass or synthetic resin, leaving a space therebetween, said inner container and said outer container being made into a single body by the joining of the rims of their respective mouths, wherein

a thermal radiation preventing layer through which visible rays can pass is formed on at least one surface of a surface of said inner container and a surface of said outer container which are on opposite sides of and face onto said space.

A manufacturing method for a transparent insulated container comprising

arranging a thermal radiation preventing layer through which visible rays can pass onto at least one surface of an outer surface of an inner container having a bottom and comprising a transparent material such as synthetic resin or glass and an inner surface of an outer container having a bottom slightly larger than said inner container and comprising a transparent material such as synthetic resin or glass;
then putting said inner container within said outer container;
arranging said inner container and said outer container leaving a space therebetween;
joining said inner container and said outer container into a single body by welding the rims of their respective mouths;
and thereby
forming a container having a double walled structure of said inner container and said outer container.

A manufacturing method for a transparent insulated container comprising

arranging a thermal radiation preventing layer through which visible rays can pass onto at least one surface of an outer surface of an inner container having a bottom and formed from a transparent material such as synthetic resin or glass and an inner surface of an outer container having a bottom slightly larger than said inner container and provided with an aperture and formed from a transparent material such as synthetic resin or glass;
then putting said inner container within said outer container;
arranging said inner container and said outer container leaving a space therebetween;
joining said inner container and said outer container into a single body by welding the rims of their respective mouths to form a container having a double walled structure of said inner container and said outer container;
filling said space with a gas having low thermal conductivity via said aperture;
and
sealing said aperture by attaching a sealing plate.
