Abstract
A reagent bottle and cap assembly includes a bottle which may be positioned in current apparatus in such a manner that the removal of fluids is maximized. The cap has a flip-top with a live hinge and live over-center spring for holding the cap in an open position and includes a conical core which is in communication with a wiper blade for breaking the meniscus or fluid seal between the core and the neck to enhance the flow of fluids which have collected on the cap back into the bottle for minimizing evaporation.

A container for a reagent, comprising a container having a neck with an open top and a removable cap for selectively closing the top, said cap including
- a. an outer portion having a central aperture receiving said neck;
- b. an integral inner portion movable between opened and closed positions and disposed in the open top when in the closed position;
- said inner portion including a cylindrical core substantially concentric with the neck of the container when the cap is placed thereon, and
- a conical tip depending from the core and extending into the neck;
- and
- c. an annular wiper blade on said outer portion and in communication with the conical tip at the intersection of the tip and the core when said inner portion is in the closed position.
A container for a reagent, comprising a container having a neck with an open top and a removable cap for selectively closing the top, said cap including
- a. an outer portion having a central aperture receiving said neck;
- b. an integral inner portion movable between opened and closed positions, said inner portion having a cylindrical core substantially concentric with the neck of the container and disposed in the open neck when in the closed position, and a conical tip depending from the core and extending into the neck;
- c. an annular wiper blade on said outer portion and in communication with the conical tip at the intersection of the tip and the core when said inner portion is in the closed position;
- and
- d. means for selectively biasing the inner portion into the opened position.
A container for a reagent, comprising a container having a neck with an open top, a closed bottom, a substantially cylindrical side wall, and a peripheral rim near the top of the neck and extending about the perimeter thereof, and a removable cap placed over the open neck in non-interfering relationship with said rim for selectively closing the top, said cap further including:
- a. an outer portion having a central aperture receiving said neck;
- and
