ABSTRACT:
The container has an elongated port section formed of a flexible cylindrical wall. A first tube member is lodged within the wall at a location spaced from the end thereof. A second tube member is forceably inserted within the first tube member, engaging a section of the wall therebetween. The engaged wall section may include a double wall thickness. One of the tube members is composed of substantially non-elastic material and the other is composed of relatively elastic material. The elastic member will deform so as to tightly seal the wall section. A detent may be present on one of the tube members to cooperate with a detent receiving recess on the other to enhance the strength of the seal. Any conventional drain valve or tubing can be connected to the protruding end of the second tube member.
