To provide a top-seal container holder that improves stability of a top-seal container placed on a table, ensures stable grasping of the top-seal container, and improves thermal insulation effect of the top-seal container.

A holder main body 15 is in the form of a cylinder that broadens towards its bottom. Therefore, when the holder main body 15 holding the top-seal container 11 therein is placed on a table, stability of the top-seal container 11 is enhanced. Because the holder main body 15 is larger than the top-seal container 11, the top-seal container 11 can be grasped stably. In addition, because an empty space is defined between the holder main body 15 and the container main body 12, thermal insulation is high. Accordingly, coffee or tea in the container main body 12 can be kept warm for a long time.
