Title:
BOTTLE-SHAPED CAN AND CAPPED BOTTLE-SHAPED CAN
Document Type and Number:
WIPO Patent Application WO/2019/039184
Kind Code:
A1
Abstract:
The present invention addresses the problem of improving the shape of a curled portion of a capped bottle-shaped can such that the sealability of the capped bottle-shaped can when filled with contents is not compromised even upon impact such as from being dropped on its top. The bottle-shaped can (1) has a curled portion (10) at an open end of a mouth portion and is characterized in that the curled portion (10) has an upper end curved section (11) where an upper part of a neck shoulder section (20) of the mouth portion is curved outward and an outer wall section (12) which extends downward from the upper end curved section (11), a predetermined angle (θp) at which an outer edge side of a lower end face (12P) of the outer wall section (12) opens is formed between the lower end face (12P) of the outer wall section (12) and the neck shoulder section (20), and an inner edge (12Pe) of the lower end face (12P) comes into contact with the neck shoulder section (20) when a downward load is applied to the curled portion (10) from above.
