Abstract
A fluid component separation system includes a container that has an upper end comprising a threaded neck. The container has a first fluid therein. A housing has a top wall and a perimeter wall. The perimeter wall has a lower section that includes the bottom edge. An inner surface of the lower section is threaded and is threadably coupled to the threaded neck. A membrane is mounted in the housing and divides the lower section from an upper section of the housing. The upper section has a second fluid therein. A shaft has a top end and a bottom end. The shaft extends through the top wall and the top end is positioned above the top wall. The bottom end is pointed. The shaft is extendable downwardly through the membrane to pierce the membrane and empty the second fluid into the first fluid.
Claims5
A fluid separation assembly to allow selective mixing of two fluids, said assembly comprising:
- a container having an upper end comprising a threaded neck, said container having a first fluid therein;
- a housing having a top wall and a perimeter wall being attached to and extending downwardly from said top wall, said perimeter wall having a bottom edge, said perimeter wall including a lower section including said bottom edge, an inner surface of said lower section being threaded and being threadably coupled to said threaded neck;
- a membrane being mounted in said housing and dividing said lower section from an upper section of said housing, said upper section having a second fluid therein;
- a shaft having a top end and a bottom end, said shaft extending through said top wall and said top end being positioned above said top wall, said bottom end being pointed, said shaft being extendable downwardly through said membrane to pierce said membrane and empty said second fluid into said first fluid;
- and
- a lower wall being mounted rotatably mounted in said lower section and being positioned between said membrane and said bottom edge, said lower wall abutting said membrane, said lower wall having an opening extending therethrough being spaced from a center area of said lower wall, said shaft including a first section extending through a central area of said top wall and a second section including said bottom end, said first section being offset from said second section to allow said bottom end to be extended through said opening when said aligned with said bottom end.

- a container having an upper end comprising a threaded neck, said container having a first fluid therein;
- a housing having a top wall and a perimeter wall being attached to and extending downwardly from said top wall, said perimeter wall having a bottom edge, said perimeter wall including a lower section including said bottom edge, an inner surface of said lower section being threaded and being threadably coupled to said threaded neck;
- a membrane being mounted in said housing and dividing said lower section from an upper section of said housing, said upper section having a second fluid therein;
- a shaft having a top end and a bottom end, said shaft extending through said top wall and said top end being positioned above said top wall, said bottom end being pointed, said shaft being extendable downwardly through said membrane to pierce said membrane and empty said second fluid into said first fluid;
- a lower wall being mounted rotatably mounted in said lower section and being positioned between said membrane and said bottom edge, said lower wall abutting said membrane, said lower wall having an opening extending therethrough being spaced from a center area of said lower wall, said shaft including a first section extending through a central area of said top wall and a second section including said bottom end, said first section being offset from said second section to allow said bottom end to be extended through said opening when said opening is aligned with said bottom end;
- a grip being attached to said lower wall to facilitate rotation of said lower wall;
- a sleeve being attached to bottom surface of said top wall, said shaft extending through said sleeve;
- and
- a seal being mounted on said shaft, said seal being positioned in said sleeve to prevent air from entering said upper section when said bottom end is positioned within said upper section, said seal being positioned below said sleeve to allow air to enter said upper section when said bottom end is extended through said membrane.
