Varialbe pour flow device
A cap for a variable pour flow device is configured to close an opening of a container holding a liquid when assembled with the container. The cap includes a spout in communication with an interior of the container when the cap is assembled with the container. The cap is further configured to provide a first fluid flow in which fluid flows through a first passage and the spout when the container with the cap assembled thereto is tilted from an upright position toward the spout to an intermediate degree. The cap is also configured to provide a second, greater fluid flow in which fluid flows through the first passage, a larger second passage, which is spaced from the first passage, and the spout when the container with the cap assembled thereto is tilted further toward the spout from the intermediate degree.

and the cap further includes an insert having a baffle defining the first passage and the second passage,
wherein a longitudinal plane bisects the cap along which a central axis of the cap resides, and the first passage and second passage are located on opposite sides of the plane, with the first passage located closer to the spout than the second passage.
2. The cap for the variable pour flow device of claim 1 , wherein fluid does not flow through the second passage when the container is tilted to the intermediate degree.
3. The cap for the variable pour flow device of claim 1 , wherein the first passage and the second passage are disposed adjacent opposite ends of the baffle.
4. The cap for the variable pour flow device of claim 1 , wherein the cap defines a cap interior, and an air vent disposed in the cap terminates in the cap interior at a vertically higher location than a lower most end of the baffle adjacent the second passage when the cap is in the upright position.
5. The cap for the variable pour flow device of claim 1 , wherein the first passage is located closer to the spout than the second passage.
6. The cap for the variable pour flow device of claim 1 , wherein the baffle defines a channel in communication with the first passage and the second passage having a substantially square U-shaped cross section taken normal to a longitudinal direction of the channel.
7. The cap for variable pour flow device of claim 1 , wherein the insert is made of flexible material.
8. The cap for the variable pour flow device of claim 7 , wherein the cap further includes an air vent configured for communicating air pressure between the interior of the container and the exterior of the container, and a boss extending downwardly from a cover toward the interior of the container when the cap is assembled with the container in the upright position, and wherein the air vent is a through hole disposed through the boss, and the insert made from the flexible material engages the container and the boss.
9. The cap for the variable pour flow device of claim 1 , wherein the cap includes threads configured for engaging the container.
10. The cap for the variable pour flow device of claim 9 , wherein the cap includes a flange facing the interior of the container when the cap is assembled with the container, and the cap further includes a gasket seated on the flange, the gasket being configured to engage the container when the cap is assembled with the container.
11. The cap for the variable pour flow device of claim 10 , wherein the cap includes an upper cap member having a ridge that faces the interior of the container when the cap is assembled with the container, the ridge being configured to support the flange against the gasket when the cap is assembled with the container.
12. The cap for the variable pour flow device of claim 1 , wherein the cap includes an upper cap member having a ridge that faces the interior of the container when the cap is assembled with the container, the ridge being disposed adjacent a periphery of the upper cap member.
13. A cap for the variable pour flow device configured to close an opening of a container holding a liquid when assembled with the container, the cap including a spout in communication with an interior of the container when the cap is assembled with the container, the cap being configured to provide:
a first fluid flow in which fluid flows through a first passage and the spout when the container with the cap assembled thereto is tilted from an upright position toward the spout to an intermediate degree; and
a second, greater, fluid flow in which fluid flows through the first passage, a larger second passage, which is spaced from the first passage, and the spout when the container with the cap assembled thereto is tilted further toward the spout from the intermediate degree;
and the cap further includes an insert having a baffle defining the first passage and the second passage,
wherein the cap further includes a gasket disposed within the cap configured to engage the wall of the container when the cap is assembled with the container, wherein the baffle and the gasket are integrally formed.
14. The cap for the variable pour flow device of claim 13 , wherein the baffle and the gasket are integrally formed from silicone.
15. A variable pour flow device, comprising:
a container formed by a wall having an inner surface defining an interior and an outer surface defining an exterior, the container having an end defining an opening;
a cap assembly including:
a cover configured to substantially close the opening of the container when the cap is assembled with the container, such that the cover has a cover inner surface facing the interior of the container;
a cap wall extending from the cover and configured for engaging the container around the opening of the container, such that the cap wall has a cap wall inner surface;
a spout configured for communicating liquid between the interior of the container and the exterior of the container; and
a channel along the cover having at least two passages configured to communicate an inside of the channel with the interior of the container, and an open end directed toward the spout;
wherein tilting the container from an upright position towards the spout to an intermediate degree with the cap assembled to the container facilitates fluid flow into the channel through a first passage of the at least two passages, and further tilting the container from the intermediate degree towards the spout facilitates fluid flow into the channel through a second passage, of the at least two passages;
wherein the channel and the at least two passages are at least partially defined by a baffle extending from the cover;
wherein the cap further includes a gasket disposed within the cap, the gasket being integrally formed with the baffle and configured to engage the container when the cap is assembled with the container.
16. The variable pour flow device of claim 15 , wherein the first passage of the channel is smaller than the second passage of the channel.
17. The variable pour flow device of claim 15 , wherein the cap includes an air vent spaced from the spout, the first passage, and the second passage, the air vent being configured for communicating air pressure between the interior of the container and the exterior of the container.
