摘要：
In one general aspect, the present disclosure provides a drainage system. The drainage system may include a container having an interior and a mouth, the mouth having an outer surface and an opening. A frangible seal may cover the opening. A cap may be secured to the mouth, and the cap may be in fluid communication with a drainage line. The cap may have an inner surface for engaging with the outer surface of the mouth. The drainage system may further include a retention ring with a collar having an inner surface configured to engage an outer surface of the cap, where the retention ring includes a bead for at least partially concentrating a restriction force provided by the retention ring on an adjacent area of the outer surface of the cap.
