Combined lid and pouring spout for a container having a U-shaped sealing channel |
摘要 |
A lid is disclosed for a conventional liquid container of the type having an annular U-shaped sealing channel at the open end thereof. The lid includes an upwardly-cambered disc-shaped base having a tapered annular skirt depending downwardly from the base near its periphery. A plurality of wedge-shaped tangs depend downwardly from the skirt in a radial pattern each tang being separated by a square interstice to allow independent movement of the tangs. A sealing groove is formed around the skirt between the tangs and the base for securely engaging the inside of the channel and thereby preventing liquid from entering the channel. A conically-shaped pouring spout preferably projects upwardly from the base at an inclined attitude to provide access for ambient air to the inside of the container during pouring thereby promoting a controllable rate of flow. The spout is provided with a specially configured end having a flared lip to minimize dripping after pouring is completed. The lid may be characterized as a virtually universally fitting, snap-on, self-locking, air-tight container cover, further featuring a self-venting, virtually dripless pouring spout.
