Filtrate storage system
View Patent ↗A method of removing a filtrate storage bottle from a water bath includes inserting at least two finger underneath a radially protruding lip of a filtrate storage bottle sealing cap and raising the at least two fingers to lift the bottle from the water bath. A side wall portion of the filtrate storage bottle sealing cap is smaller in perimeter than a circle surrounding the radially protruding lip. The cap creates a liquid tight seal with the filtrate storage bottle.

a filtrate storage bottle; and
a filtrate storage bottle sealing cap characterized by:
an upper portion having a top surface and a radially protruding lip comprising an outer edge; and
a side wall portion connected to the upper portion, the side wall portion having an outer surface with a smaller perimeter than the radially protruding lip, the side wall portion also having an inner surface including a thread forming a helical ridge.
2. A filtrate storage system according to claim 1 , wherein the outer edge includes surface ridges thereon.
3. A filtrate storage system according to claim 1 , wherein the outer surface of the side wall portion decreases in perimeter away from the upper portion.
4. A filtrate storage system according to claim 1 , wherein the outer surface of the side wall portion concaves radially inward.
5. A filtrate storage system according to claim 4 , wherein a section of the side wall outer surface has a constant perimeter.
6. A filtrate storage system according to claim 1 , wherein the top surface of the upper portion is flat.
7. A filtrate storage system according to claim 1 , wherein the top surface of the upper portion is specially adapted to receive labeling information.
8. A filtrate storage system according to claim 1 , further comprising a plurality of ribs connected to the side wall portion and the radially protruding lip.
9. A filtrate storage system according to claim 8 , wherein the plurality of ribs has a concave profile.
10. A filtrate storage system according to claim 1 , further comprising a sealing ring extending from a bottom surface of the upper portion.
