A hollow tube attachable at one end to a container of fluid is provided at the other end with a fluid conduit termination disk separated from the end of the hollow tube by a space that defines a fluid discharge opening. A slide valve on the exterior of the tube is biased into a closed position engaging the fluid conduit termination disk and precluding fluid transfer until the discharge opening is inside a receiving vessel. A barricade is disposed across the interior of the tube at an inclination relative to the longitudinal axis thereof. Formed through the barricade is at least one elongated aperture extending continuously from a first longitudinal position in the tube to a second longitudinal position in the tube that is located further from the container of fluid than is the first longitudinal position. When the slide valve is opened, fluid passes through the barrier at the first longitudinal position, while air is simultaneously exchanged therethrough at the second longitudinal position, venting the container of fluid.

[ What is claimed is:] [1.] A pour spout for permitting transfer of a fluid from a container of the fluid to a receiving vessel, the pour spout comprising:(a) a fluid conduit opening at one end thereof into the container of fluid, said fluid conduit being provided at a location remote from the container with a fluid discharge opening through which fluid from the container is transferred into the receiving vessel;(b) closure means for precluding any transfer of the fluid through said discharge opening into the receiving vessel until said fluid discharge opening is inside the receiving vessel, said closure means comprising:(i) a slide valve having a closed position in which transfer of the fluid through said discharge opening is precluded;(ii) a spring urging said slide valve into said closed position thereof; and(iii) slide valve release means for co-acting with the receiving vessel to move said slide valve out of said closed position when said fluid discharge opening on said fluid conduit enters into the receiving vessel; and(c) baffle means located in said fluid conduit for (1) admitting air into the interior space within said fluid conduit and the container at a first longitudinal position in said fluid conduit, and (2) maintaining the point of zero static head pressure in fluid flowing through the baffle means at a second longitudinal position located further from the container of fluid than said first longitudinal position, said baffle means comprising a plate disposed across the interior of said fluid conduit at an inclination relative to the longitudinal axis thereof, said plate having an air vent aperture formed therethrough at said first longitudinal position in said fluid conduit and a fluid aperture formed therethrough at said second longitudinal position in said fluid conduit.
