    Abstract: A vacuum insulated container is constituted by a double-walled receptacle wherein the space between the walls is substantially evacuated to provide vacuum insulation. The outer wall is provided with an opening therein which is used during manufacture to provide access to the space between the walls so that the space may be evacuated. A stopper- or plug-like portion fills the opening after the container has been evacuated and is permanently joined or bonded to the surfaces of the opening thereby providing a sealing to maintain the vacuum in the space between the walls. The apparatus and method of manufacturing such a container include means for and the steps of: forming the opening by piercing the outer wall; providing a sealed chamber in which the container may be placed on a movable support after a sealing element is placed on the opening; evacuating the chamber; heating the container in the vicinity of the opening with the sealing element resting therein; and deforming the sealing element to cause it to completely seal the opening and bond to the container wall after it has been heated to a temperature permitting the material to flow.

    Abstract translation: 真空绝热容器由双壁容器构成,其中壁之间的空间被基本抽真空以提供真空绝热。 外壁在其中设置有开口,其在制造期间被使用以提供对壁之间的空间的通路,从而可以将空间抽真空。 在容器已被抽真空之后,塞子或塞状部分填充开口,并且永久地接合或结合到开口的表面,从而提供密封以将真空保持在壁之间的空间中。 制造这种容器的装置和方法包括以下步骤:用于穿过外壁形成开口; 提供密封室,其中密封元件放置在开口上之后容器可以放置在可移动支撑件上; 疏散室; 在密封元件处于其中的情况下加热开口附近的容器; 并使密封元件变形,使其在被加热到允许材料流动的温度之后完全密封开口并结合到容器壁。
