The present disclosure relates to a pilferproof cap assembly(100) for a container(10). The assembly(100) is configured to facilitate refilling and decanting of fluid in the container(10). The assembly(100) comprises a neck housing(12) and an adaptor(40). The neck housing(14) is configured to be fitted on an opening of the container(10). The neck housing(12) is provided with a linearly displaceable diaphragm(24) to define a fluid-orifice(50) for fluid flow, and an air-orifice(30) to facilitate air flow. The adaptor(40) is configured to be mounted on an operative top of the neck housing(12) and is further configured to actuate the fluid-orifice(50) and the air-orifice(30) in an operative configuration of the assembly(100). The assembly thus facilitates the refilling and decanting of fluid therefrom in a pilferproof manner.

A measuring and dispensing device for a flowable material has a cap body configured to be removably secured to a container, the cap body having a bottom wall that extends across the container and has a bottom aperture configured to allow the flowable material to pass from the container into the cap body. A top housing extends over the bottom aperture, the top housing including a top wall having a top aperture. A metering button is slidably mounted within the top housing for rectilinear movement between a closed position and a dispensing position. A metering bore is formed through the metering button, the metering bore being aligned with the bottom aperture in the closed position to receive a predetermined volume of the flowable material, and being aligned with the top aperture in the dispensing position to dispense the predetermined volume of the flowable material. A biasing mechanism is disposed within the cap body for biasing the metering button toward the closed position.
