A cylindrical plug (10) attached to a pouchy container proper capable of varying shape as passed through the container proper (1) in such a manner that one terminal side thereof is positioned inside the container proper (1) and the other terminal side thereof positioned outside the container proper (1). This plug comprises a split pipe (18) joined to one terminal side of the plug and divided into two halves along the longitudinal direction thereof so as to be provided with interstices (19) intercommunicating between the inside and the outside and a joint plate (17) for integrally coupling one and the other half of the split pipe. It, therefore, secures a path for air or liquid during the aspiration of the liquid from the interior of the container proper (1). When the container proper (1) happens to develop negative pressure, the plug prevents the path for the liquid from being blocked owing to the flexibility of the container proper (1), precludes the occurrence of a dead space for stagnating liquid in the upper part of the container proper (1), and enables the split pipe (18) to retain the shape and the strength thereof.

[ What is claimed is:] [1.]1. A cylindrical plug attached to a pouch container, the pouch container capable of varying its shape, the cylindrical plug having one terminal side positioned inside the pouch container, the cylindrical plug having a second terminal side positioned outside said pouch container comprising:a split pipe connected to the one terminal side and divided into two halves along its longitudinal direction, so that the split pipe is provided with interstices intercommunicating between the inside and the outside of the split pipe, anda joint plate for integrally coupling the two halves of the split pipe,the two halves of the split pipe joined by said joint plate, the joint plate having a S shape, with each side of the S shape having a continuous uninterrupted surface, so that the thickness of the S shape is constant along the total length of the S shape.
