CONTAINER CAP

摘要

When the temperature of an external environment is decreased, for example, a heat radiating portion 12a whose surface area is increased by convex portions 12b and 12c provided on the external surface of a cap body 12 actively radiates heat of the external surface of the cap body 12 and thus promotes cooling. Consequently, condensation forms on the inner surface of the cap body 12 before condensation forms on the external surface of a container covered by the cap body 12. The condensed drops are trapped, by surface tension, in a concave portion 12d of a liquid trapping portion 12k provided on the inner surface of the cap body 12. The drops can be prevented from adhering to the external surface of the container covered by the cap body 12.
