Claims

[Scope of utility model registration request]

A liquid conduction means having a large diameter part and a small diameter part connected to the large diameter part at the tip, a liquid supply container having a through hole in the container body into which the liquid conduction means is inserted and connected, and the small diameter part. and a sealing member that surrounds the through-hole and is expandable in volume, and when the connection is made, the sealing member expands in volume with the small-diameter portion located in the through-hole, thereby sealing at least the container body in the vicinity of the through-hole. A liquid supply device configured to come into close contact with the part.
