Description

[Detailed Description of the Invention] The present invention relates to the structure of a pouring part in a thermos container, such as a magic bottle, in which the liquid content is injected from the top and poured out from the bottom. In conventional heat-insulating containers of this type, a heat-insulating inner container is housed within an outer package, and the inner container has an opening for pouring and dispensing only at the top. Therefore, when pouring out the contents, there were inconveniences such as having to lift and tilt the entire heat-insulating container to pour out the contents, and having to repeatedly operate the air pump. In this invention, openings are formed at the top and bottom of the medium container, and the upper opening is used as the inlet for the liquid content, and the lower opening is connected to the spout, so that the liquid flows from the bottom of the container due to its own weight. It was designed to flow out.

By the way, conventional thermal containers only have an opening at the top for pouring and dispensing, so when washing the inside of the inner container, you can easily wash it by inserting a brush etc. through the opening. However, in the case where the liquid is poured from the lower opening of the inner container as described above, it is extremely difficult to clean the spouting part from the lower opening to the spouting part.

The present invention has been devised in view of the above circumstances, and includes a spout unit that is detachably attached to the bottom of the exterior body, and a spout unit that is connected to the lower opening of the inner container. These structures are connected via a flexible member, and the lower part of these structures is covered with a bottom cover, so that the spout unit can be removed and cleaned if necessary. be.
