ABSTRACT:
A completely enclosed plastic can or container has a neck-like opening closed by a spring biased cap. The cap is controlled by a handle linkage connected to a vertical fin formed on the can by an enlargement of the flash line between two plastic mold parts, which are joined together to mold the container, preferably by a blow molding process. Springs automatically urge the cap and handle to a closed position when the container is sitting at rest. The cap opens as the can is tipped while the handle is being held. A clip-on pouring spout is snapped onto the neck to guide the fluid flowing from the can.
