A pouring spout for a liquid container, the pouring spout including a pliable plastic sheet defining one side of the pouring spout and freely movable towards and away from an opposite side of the pouring spout to close and open the pouring spout for dispensing liquid therethrough. The pliable plastic sheet is dimensioned such that when liquid is not being dispensed from the pouring spout, the pliable plastic sheet moves towards and into contact with the opposite surface and adheres thereto by surface tension to produce a self-sealing action with respect to the pouring spout.

The lid of claim 8, wherein the door opens in two stages, the tab engaging the upper notch during the first stage and engaging the lower notch during the second stage.13. The lid of claim 12, wherein the first and second stages correspond to two unequal downward pressures on the push section of the door.14. The lid of claim 12, wherein the flip section is limited in rotation to a first degree α relative to the main body in the first stage, and limited in rotation to a second degree ß relative to the main body in the second stage, wherein ß is greater than α.15. The lid of claim 14, wherein ß is less than 90°.16. The lid of claim 8, wherein the position of the hinged connection between the push and flip sections relative to the pivot wall, and the depth of the recess, are both controlled to limit the rotation of the flip section relative to the push section to less than 90°.17. The lid of claim 8, wherein the recess includes a floor, a portion of the floor below the push section being angled downwardly and inwardly from a position adjacent the hinged connection of the push section and main body.18. The lid of claim 10, further comprising an aperture in a floor of the recess and a sealing ring projecting from an underside of the flip section of the door, the sealing ring sized to engage the outer periphery of the aperture.19. The lid of claim 10, wherein downward pressure on the push section results in the flip section disengaging the main body prior to the tabs disengaging the upper notches.20. The lid of claim 10, wherein downward pressure on the push section results in the flip section disengaging the main body at about the same time as the tabs disengage the upper notches.21. A lid for a container comprising: a planar body having a recess therein defining a pivot wall; a door received within the recess, the door comprising a flip section pivotally connected to a push section, the push section pivotally connected to the main body with no hinge pins; the flip section engaging the pivot wall for rotation relative to the push section in response to downward pressure on the push section; and the push section having a detent mechanism to control opening of the flip section between at least two locked positions corresponding to open and closed positions of the flip section. 22. The lid of claim 21, wherein the push section is parallel to the main body in the first locked position, and is angled downwardly and inwardly in the second locked position.23. The lid of claim 21, wherein the push section is operable between three locked positions corresponding to closed, first open and second open positions of the flip section, the flip section being rotated more in the second open position than the first open position.24. The lid of claim 21, wherein the recess further defines two opposing side walls, and wherein the detent mechanism comprises two vertically spaced notches in each opposing side wall and a tab on opposing sides of the push section positioned to sequentially engage the two notches in the respective side wall.25. A lid for a container comprising: a main body having a recess therein defined by a pivot wall, a rear wall and a floor; a door comprising a flip section pivotally connected to a push section, the push section pivotally connected to the main body adjacent the rear wall, over the recess and without any hinge pins; the flip section engaging the pivot wall upon the push section moving downwardly in the recess to rotate the flip section toward the push section to open the lid; and a majority of the floor of the recess being angled downwardly and inwardly from the rear wall towards the pivot wall. 26. The lid of claim 25, wherein the push section is disposed proximate the angled portion of the floor when in the open position.27. The lid of claim 26, wherein the floor limits the flexure of the push section.28. The lid of claim 23, wherein the angled p
