ABSTRACT:
A fluid container, especially one formed of plastic, including a hollow body and a neck portion with an opening at the end thereof. A breakable seal for holding the fluid in the container is positioned in the neck between the hollow body and the container opening at the end of the neck. A cap at the container opening is optional but preferred. With the cap removed and the container tilted up side down with the container opening positioned inside or above the fluid receptacle, compression of the outside of the neck adjacent or nearly adjacent to the seal inside the neck, as applied with thumb and forefinger, causes the seal to break or separate allowing fluid to flow from the container into the receptacle without spillage.
