Pour spout

A pour spout for permitting transfer of a fluid from a container of the fluid into a receiving vessel, the pour spout comprising:

• (a) a fluid conduit opening at one end thereof into the container of fluid;
• (b) a fluid conduit termination disk supported at a distance from the end of said fluid conduit remote from the container of fluid, thereby to define between said fluid conduit termination disk and the end of said fluid conduit remote from the fluid container a fluid discharge opening through which fluid from the container is transferred into the receiving vessel;
• (c) 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;
• and
• (d) a barrier to flow of the fluid comprising a planar structure disposed across the interior of said fluid conduit at an inclination relative to said longitudinal axis thereof, said planar structure having formed therethrough an air vent aperture at a first longitudinal position in said fluid conduit and a fluid aperture at a second longitudinal position in said fluid conduit located remote from said first longitudinal position relative to the container of fluid.

A pour spout for permitting transfer of a fluid from a container of the fluid into 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) a fluid conduit termination disk supported at a distance from the end of said fluid conduit remote from the container of fluid, thereby to define between said fluid conduit termination disk and the end of said fluid conduit remote from the fluid container a fluid discharge opening through which fluid from the container is transferred into the receiving vessel;
• (c) a slide valve having a closed position in which transfer of the fluid through said discharge opening is precluded;
• (d) a spring urging said slide valve into said close position thereof;
• (e) slide valve release means for co-acting with the receiving vessel to move said slide valve out of said close position when said fluid discharge opening on said fluid conduit enters into the receiving vessel;
• and
• (f) 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 a second longitudinal position in said fluid conduit.
