A cup-like measuring device for dispensing liquid from a container having a neck portion and a threaded closure cap, said device having a cylindrical plastic body portion provided with an unrestricted open end and a closed end; said cylindrical portion in a stored condition capable of extending into the container neck with the open end directed downwardly so as to drain into the container any residual liquid remaining therein after use; said closed end of the device having a flat peripheral shoulder extending outwardly normal from said body which in said stored position extends into the closure cap to form an annular seal when said cap is clamped to the container neck portion; said plastic shoulder being sufficiently thin to be flexible for threading into and secured within the threaded cap; at least a portion of said body portion being made of material capable of transmitting light so that in an inverted liquid-receiving position the level of the fluid substance contained therein can be observed through the device; graduated indicia on said body for measuring the level of fluid in the device to be dispensed from the container; and said peripheral shoulder has a concentric scribe mark to provide a cutting guide to enable the shoulder to be trimmed off to fit into various size container caps.
