ABSTRACT:
The a fluid-tight receptacle comprises a container with a neck portion, a cup-shaped member tightly engaged within the neck portion, a cap threadedly engaged with the neck portion, a resilient liner inside the cap, and a float member slidably and concentrically mounted within the cup-shaped member; the float member has a cup portion so dimensioned as to lie within the cup-shaped member so that tight engagement of the cap to the neck portion forces the rim of the cup-shaped member to sink in the resilient liner of the cap; this prevents fluid leakage from the container during transport or as a result of accidental tip of the container.
