PLUG AND AMORPHOUS CONTAINER USING THE PLUG

摘要

A cylindrical plug (10) fitted to a container main body (1) to penetrate through the main body so that one of the ends thereof is positioned inside a container main body (1) having a shape of a deformable bag and the other end thereof is positioned outside the container main body, comprising a two-split pipe (18) so split in a longitudinal direction as to provide a gap (19) connected to one of the ends and providing communication between the inside and the outside, and a coupling plate (19) for integrally connecting one half of the split pipe (18) with the other half. When a liquid inside the container main body (1) is sucked, a passage of air and the liquid can be secured and when the inside of the container main body (1) reaches a negative pressure, the liquid passage is prevented from closing by flexibility of the container main body (1) and a dead space where the liquid remains is prevented from being formed at the upper part of the container main body (1), and the shape and the strength of the split pipe (18) can be secured. <IMAGE>
