ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a pour spout for a container. More particularly, the present invention relates to a self-stopping spout that vents air as a fluid is coincidentally poured.
SUMMARY OF THE PRESENT INVENTION
The present invention relates to a spout for a container. The spout includes a conduit having a first end connected to the container, an aperture and a second end adapted to be inserted into an opening. The spout also includes a closure, an opener, a vent passage disposed in the conduit and a valve. The closure prevents flow through the conduit. Specifically, the closure has a closed position that inhibits flow through the conduit and an open position that allows flow through the conduit. The opener is movably responsive to inserting the conduit into the opening. More specifically, the opener moves the closure from the closed position to the open position in response to inserting the conduit into the opening. The vent passage has an inlet and an outlet. The inlet is disposed within the aperture. The valve is disposed in the vent passage for permitting a flow of air through the inlet into the vent passage during a flow of fluid through the conduit from the container into the opening.
The present invention further relates to a spout for a container. The spout includes a conduit having a first end connected to the container, an aperture, a second end adapted to be inserted in an opening and a conduit wall connecting the first end and the second end. The spout also includes a closure, an opener, a vent passage and a valve. The closure prevents flow through the conduit. Specifically, the closure has a closed position to inhibit flow through the conduit and an open position to allow flow through the conduit. The opener is movably responsive to inserting the conduit into the opening. More specifically, the opener moves the closure from the closed position to the open position in response to inserting the conduit into the opening. The vent passage has an inlet and an outlet. The inlet is disposed within the aperture. The vent passage also has a passage wall disposed between the inlet and the outlet and in contact with the conduit wall. The valve is disposed in the vent passage for permitting a flow of air through the inlet into the vent passage during a flow of fluid through the conduit from the container into the opening.
The present invention even further relates to a spout for a container. The spout includes a conduit having a first end connected to the container, an aperture, a second end adapted to be inserted in an opening, and a conduit wall connecting the first end and the second end. The spout also includes a closure, an opener, a vent passage and a valve. The closure prevents flow through the conduit. Specifically, the closure has a closed position to inhibit flow through the conduit and an open position to allow flow through the conduit. The opener is movably responsive to inserting the conduit into the opening. More specifically, the opener moves the closure from the closed position to the open position in response to inserting the conduit into the opening. The vent passage has an inlet, an outlet, and a passage wall. The inlet is disposed within the aperture. The passage wall is disposed between the inlet and the outlet and external to the conduit wall. The valve is disposed in the vent passage for permitting a flow of air through the inlet into the vent passage during a flow of fluid through the conduit into the opening.
Other principal features and advantages of the invention will become apparent to those skilled in the art upon review of the following drawings, the detailed description and the appended claims.
