ABSTRACT:
A quick-pour container of the present invention includes a base portion, a ody portion extending upwardly from the base portion, and a spout portion integrally formed with the body portion. The spout portion has a mouth through which fluid contained in the container flows when emptying it. An upwardly extending neck portion is formed in the base portion, the neck portion defining a downwardly opening cavity. An annular wall of the neck portion terminates at its upper end to define an opening which is closed by a membrane attached to the neck portion to contain fluid in the container. A puncturing device controls and quickens the flow of fluid from the container when emptying it. The puncturing device has a member movable by manual manipulation between a fluid stored position in which it is spaced from the membrane to a puncturing position in which the member moves through the opening to puncture the membrane for allowing gas to be vented into the container when emptying the fluid from the container thereby controlling and quickening the flow of fluid therefrom.
