Methods and systems for forming vacuum insulated containers, such as beverage and food containers, are described. The methods and systems include using a laser to close openings in walls of the container while the container is held at vacuum conditions. The closing of the opening forms the vacuum space within the walls of the container.

An insulated container for food particulate and beverages is described. The insulated container includes a double-walled structure composed of a metal, and a glass structure arranged within a hollow interior of the double-walled structure. The glass structure includes a body and a sipping portion extending from the body. The sipping portion isolates the user's lips from contacting the double-walled structure. The glass structure may be repeatably removed for cleaning or replacement. The insulated structure includes a deformable flange that secures the glass structure to the double-walled structure. The insulated container may be vacuum-insulated.

An insulating container can be configured to retain a volume of liquid, and include a canister having a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The opening can be sealed by a spout adapter, the spout adapter having a spout channel extending between the internal reservoir and a spout opening, smaller than the opening of the canister. The spout opening may be sealed with a cap having a magnetic top surface, and the spout adapter may be further removably coupled to a lid that may be used as a cup into which a volume of the liquid can be poured.

A pressure capture canister is disclosed. The pressure capture canister includes a body, a cap, and a seal. The cap and the seal are positioned within the body and are arranged to allow fluid communication from outside of the pressure capture canister to within the body. The seal can be selected to melt or soften at a temperature threshold.

A configurable beverage container that insulates a disposable lidded cup (which can be of varying sizes) while a user drinks from it while travelling. A user can then remove a disposable cup for increased beverage portability while leaving the insulated portion in a desired location. Similarly, if a person chooses to drink the beverage more slowly the container will assist in maintaining the desired temperature of the beverage for a longer period of time.

A water bottle capable of freely adjusting temperature and a method for vacuumizing a sealed space thereof. The vacuumizing method includes: injecting a low-boiling point liquid into a sealed space between an inner container and an outer shell through a liquid injection hole; after the liquid injection is completed, placing a bottle mouth portion of a water bottle upside down, so that the low-boiling point liquid flows to the bottle mouth portion; heating the water bottle to vaporize the low-boiling point liquid, where since the specific gravity of the gas generated after vaporization is greater than the specific gravity of air, the air in the sealed space is lifted upward and discharged from the sealed space through the liquid injection hole; and after heating for a period of time, closing the liquid injection hole to form a vacuum or semi-vacuum state in the sealed space. The traditional vacuumizing method cannot perform vacuumizing after the conventional hand warming bottle or icing bottle is filled with a heat-conducting liquid. According to the present invention, the principle that the vaporization temperature of the low-boiling point liquid is low and the gas generated after vaporization is heavier than air is cleverly utilized for performing vacuumizing, thereby resolving the problem that the traditional vacuumizing process cannot perform vacuumizing after the sealed space is filled with the liquid.

A storage container apparatus is provided for storing air sensitive materials under a vacuum. The apparatus includes having a cylindrical container body opened at its upper end and a cap apparatus with an integral air pump to evacuate air from the container body to create a vacuum. The cap apparatus comprises an inner cap with a one-way air valve and an outer cap. The outer cap is slidably nested over the inner cap and confines a central air chamber which fills with air from the container body through the one-way air valve when pulled upwardly in a reciprocating motion. In the down stroke the air is evacuated from the air chamber through vents. The outer cap may include locking mechanism and vacuum level indicator. The outer cap may include an activated carbon cloth insert that suppresses odors from the material stored in the container.

[Object] To provide a thermal insulation container with which the heat/cold insulation effect is kept for longer time without increasing the size and weight of the thermal insulation container.

[Solving Means] The thermal insulation container includes an inner container, an outer container, and an overlap region. The inner container includes a first bottom portion, a first side wall portion that extends in a first direction from the first bottom portion and forms a first open end portion, and a first vacuum layer continuously formed inside the first bottom portion and the first side wall portion. The outer container includes a second bottom portion, a second side wall portion that extends in a second direction opposite to the first direction from the second bottom portion and forms a second open end portion, and a second vacuum layer continuously formed inside the second bottom portion and the second side wall portion. The outer container is fitted onto the inner container in such a manner that an inner surface of the second side wall portion and an outer surface of the first side wall portion face each other and forms a storage portion. The overlap region is formed in such a manner that the inner surface of the second side wall portion and the outer surface of the first side wall portion overlap each other.
