Document Type and Number:
WIPO Patent Application WO/2024/090128
Kind Code:
A1
Abstract:
Provided is a pressure vessel (1) comprising a liner (2) and an insert member (3) that are integrally formed by blow molding the liner (2). The insert member (3) has a cylindrical shape with an inner-diameter opening (27). The liner (2) is molded integrally with the insert member (3) by inserting a parison through the inner-diameter opening (27) and performing blow molding. Since the liner (2) is inserted inside the insert member (3) and is blow molded, it is possible to prevent occurrence of a pinched portion. Consequently, it is possible to improve the strength, and to prevent a fluid from leaking from between the liner (2) and the insert member (3).
