A container assembly comprising:
- a container body having an upper open end and a lower open end, said upper open end having an upper neck, said lower open end having a lower neck with a rim, said upper neck having a first securing structure, said lower neck having a second securing structure;
- a bottom cap having a bottom wall and a side wall, said bottom wall having a central portion, a peripheral portion, an outside bottom surface, and a plurality of holes disposed completely through said bottom wall, said central portion being surrounded by said peripheral portion and recessed towards said upper open end, said side wall extending upwardly from said peripheral portion, said side wall having a third securing structure that removably engages with said second securing structure for securing said bottom cap to said container body;
- and
- a sealing member being disposed between said rim of said lower neck and said bottom cap when said bottom cap is connected to said container body, wherein said bottom cap is made of a first material, said sealing member is made of a second material, and said second material is flexible, and wherein said sealing member extends through said plurality of holes and protrudes below said outside bottom surface adjacent said plurality of holes and seals said plurality of holes.
