Document Type and Number:
WIPO Patent Application WO/2010/055553
Kind Code:
A1
Abstract:
A tank structured to prevent strength of a thread from deteriorating is provided to solve the problem that the strength of the thread deteriorates due to repeated use in a thread structure of a high pressure tank. To realize the purpose, the tank comprises a mouthpiece (11) having a mouthpiece thread (42) with an outer diameter larger than the interior in the tank axial direction and having a thread formed and a valve (50 (50t)) having a valve thread (51 (51t)) supporting only part of the mouthpiece thread (42). A testing valve (50t) and a product valve (50p) different in position of valve threads (51t, 51p) for example are employed in this tank, whereby the mouthpiece thread (42 (42p)) free from deterioration in strength can be used when attaching the product valve (50p) to the mouthpiece (11).
