Abstract
A beverage container comprising a body section comprising an outer metallic wall and an inner wall, the inner wall defining an inner space for containing a liquid or material, a space adjacent to the inner wall being substantially evacuated to provide thermal insulation to the inner space, and an open-only lid sealingly attached to the body section to close an opening therein.
Claims38
A beverage container comprising:
- a body section comprising an outer metallic wall and an inner wall, the inner wall defining an inner space for containing a liquid or material, a space adjacent to the inner wall being substantially evacuated to provide thermal insulation to the inner space;
- and
- an open-only lid sealingly attached to the body section to close an opening therein.
A temperature indicator for indicating the internal temperature of an insulated container, the temperature indicator being disposed on the external surface of the container and providing a visual indication of the temperature of its contents.
A thermally insulating material comprising:
- first and second opposed flexible sheets, the sheets being impermeable;
- spacer means which is in contact with both the first and second sheets,
- wherein the space between the first and second sheets is substantially evacuated.
A method of manufacturing a thermally insulating material, the method comprising:
- attaching spacer means to one side of a first flexible, impermeable sheet;
- applying a second flexible, impermeable sheet on top of the spacer means so that the first and second sheets are spaced apart from one another;
- and
- substantially evacuating the space between the first and second sheets and forming an airtight seal between the sheets.
A container comprising:
- first and second opposed flexible sheets, the sheets being impermeable;
- spacer means which is in contact with both the first and second sheets,
- wherein the space between the first and second sheets is substantially evacuated, the combined sheets being shaped to provide an inner, insulated space for containing a substance.
A beverage container comprising, a substantially rigid outer container and an inner container disposed within the outer container, the inner container comprising:
- first and second opposed flexible sheets, the sheets being impermeable;
- spacer means which is in contact with both the first and second sheets,
- wherein the space between the first and second sheets is substantially evacuated,
- the combined sheets being shaped to provide an inner, insulated space for containing a beverage.
A beverage container comprising a substantially rigid inner container shaped to provide an inner space for containing a beverage, and an outer container disposed around the inner container, the outer container comprising:
- first and second opposed flexible sheets, the sheets being impermeable;
- and
- spacer means which is in contact with both the first and second sheets,
- wherein the space between the first and second sheets is substantially evacuated.
A beverage container comprising a body section having an outer wall and an inner wall, the inner wall defining an inner space for containing a liquid or material, a highly porous material substantially filling the space between the inner and outer walls, wherein the space containing the highly porous material is substantially evacuated.
A method of manufacturing a beverage container, the method comprising:
- inserting a flexible inner container into a rigid outer container, the inner container comprising first and second opposed flexible sheets, the sheets being impermeable, and spacer means which is in contact with both the first and second sheets,
- wherein the space between the first and second sheets is substantially evacuated.
A method of providing a visual indication of the historical temperature to which a product or material has been exposed, the method comprising placing a thermal indicator in thermally conductive contact with the product or material, the thermal indicator providing a visual indication of temperature and comprising a thermally sensitive material which exhibits a time-lag response.
