Description

  The present invention is a cover used for a liquid container having an upper opening, such as a pitcher, a large / medium mug, and the like, and holds a cooling stick in an upright state inside a liquid inner vessel. The present invention also relates to a cover set that uses a cover and a cooling stick.

  As a conventional liquid container having an open top, a container having a double wall structure on the side wall and the bottom wall and an empty space provided between the double walls is known (see Patent Document 1). This structure is intended to make it difficult for heat transferred from the outside of the side wall and the bottom wall to be transferred to the liquid.

  As another conventional liquid container, there is also known one in which a refrigerant is put into a double-walled vacant space in order to further enhance the cooling effect of the liquid or to maintain the temperature of the cooled liquid for a certain period of time. (See Patent Document 2).

  These series of liquid containers are intended to provide a heat insulating effect and a cooling effect with respect to the liquid container itself. Therefore, the present inventor has considered that the liquid is kept cold or the cooling effect is enhanced by another method, and has come to the idea of directly cooling the liquid in the liquid container.

  In order to achieve the improvement of the cooling effect not by the shape of the liquid container as in the prior art but by directly cooling the liquid, it is necessary to devise from another viewpoint. Therefore, the present inventor has come up with the use of a cover that covers the liquid container.

  In addition, not only a liquid container but a cover is wash | cleaned and reused whenever it uses it. Therefore, it is desirable that the cover be easy to wash.
