Title:
LIQUID INJECTION ATTACHMENT
Document Type and Number:
WIPO Patent Application WO/2017/208772
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a liquid injection attachment which is mounted at the distal end side of a liquid injecting implement and suppresses liquid leakage without causing the liquid injecting implement to become deformed or damaged, which simplifies the injection of a liquid into an introduction opening (injection opening), and in which a gasket is attached securely to an attachment main body without complicating the manufacturing process. This problem is solved by means of a liquid injection attachment 1 which is provided with: an attachment main body 11 including an insertion opening 11b into which a liquid injecting implement is inserted, and a liquid outflow opening 11a; a gasket mounting portion 13 formed around the distal end side of the attachment main body 11; and a gasket 12 which is mounted on the gasket mounting portion 13 and is in intimate contact with a portion around the liquid outflow opening 11a; wherein the gasket mounting portion 13 has an engaging recessed portion 14 and/or engaging protruding portions 15, 16, the gasket 12 has an engaging protruding portion 19 and/or engaging recessed portions 17, 18, and the engagement direction of the engaging protruding portion 19 and/or the engaging recessed portions 17, 18 is a direction approaching the central axis of the attachment main body 11.
