1. A sealable containing comprising:
- a tubular member having an open end and an inner wall;
a deformable sealing cap including a base and a cup shaped member extending from said base, said cup shaped member having an open end adjacent said base and a closed end comprising a generally convex end wall bulging outwardly in a direction away from said open end and being configured to occlude said tubular member when said cup shaped member is inserted through the open end of said tubular member, said cup shaped member including a tubular section between said base and generally convex end wall, said tubular section having a frustoconical outer and inner wall surface, the diameter of said wall surfaces adjacent said generally convex end wall being less than the diameter of said wall surfaces adjacent said base, said sealing cap including means for securing said sealing cap to said tubular member; and
a locking cap coupled to said base, said locking cap having a portion configured for being received within said cup shaped member and sized to prevent said convex end wall from being inverted into a concave configuration when said cup shaped member is positioned in said tubular member and said portion of said locking cap is positioned within said cup shaped member.
