CAN FOR FOAMING DRINK HAVING ROUGH SURFACE ON INNER SIDE OF COVER

摘要

PROBLEM TO BE SOLVED: To provide a can which is used for filling foaming drinks such as beer, foaming alcohol or the like and has many convex and concave portions formed around a spout (a drinking mouth) of a can cover to enjoy sudsing. SOLUTION: The can for foaming drinks comprises a bottom possessing body and a cover 10 sealing the upper portion of the bottom possessing body wherein a rough surface portion 20 formed of many projections or concave portions is formed on the inner side surface around an opening portion 14 in the cover 10. This accelerates sudsing by an effect of the rough surface around the opening portion and enables the spout of the foaming drinks with qualified bubbles when the content is poured out from the opening.
