Abstract: A shield for a pop top beverage container that provides a barrier to foreign objects entering or exiting the container while permitting the flow of liquid from the container. The shield is formed of resilient and flexible material and is positioned adjacent to the inside of a shearable tab of a pop top container and secured there so that when the shear tab of the pop top is displaced inward into the container.quadrature.it causes the shield to deflect inward to permit the shear tab to pass and there after, resiliently repositions itself so that it forms a liquid traversable barrier positioned in the opening created by the displacement of the shearable tab.
