Abstract
A cylindrical plug (,) attached to a pouchy container proper capable of varying shape as passed through the container proper (,) in such a manner that one terminal side thereof is positioned inside the container proper (,) and the other terminal side thereof positioned outside the container proper (,). This plug comprises a split pipe (,) 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 (,) intercommunicating between the inside and the outside and a joint plate (,) 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 (,). When the container proper (,) happens to develop negative pressure, the plug prevents the path for the liquid from being blocked owing to the flexibility of the container proper (,), precludes the occurrence of a dead space for stagnating liquid in the upper part of the container proper (,), and enables the split pipe (,) to retain the shape and the strength thereof.
