Abstract

A closure can include a base having an opening. The base can be connected to a container such that a liquid in the container, for example a creamer, is pourable through the opening of the closure into a beverage cup. The closure can include an overcap having a plug, and the plug can seal the opening when the overcap is in a closed position relative to the base. A hinge can connect the overcap to the base and be biased to establish and maintain an angle of the overcap when the overcap moves out of the closed position. Liquid retained on the overcap during opening of the overcap can then fall directly into the beverage cup during pouring due to the angle of the overcap in the open position. Any retained liquid ingredient that falls from the overcap onto the base can be confined within a ring on the base.

First claim

The invention is claimed as follows:

1. A closure comprising:
a base comprising a first surface comprising an opening, the base configured to be connected to a container such that a liquid in the container is pourable from the container through the opening, and the first surface defines a plane of the base;
an overcap comprising a body and a plug, the plug is configured to seal the opening when the overcap is in a closed position relative to the base, wherein the body defines a plane of the overcap, wherein the plane of the overcap extends through a top surface of the overcap when the overcap is in the closed position, and the plug extends from the body in a main extension direction to which the plane of the overcap is perpendicular; and
a hinge configured to connect the overcap to the base, the hinge is biased to maintain an open position of the overcap relative to the base, and the hinge is configured such that the plane of the overcap and the plane of the base define an angle of 125 degrees to 145 degrees when the overcap is in the open position;
the first surface of the base further comprises a ring configured to retain a portion of the liquid on a section of the first surface within the ring, the base comprises a spout extending from the first surface along at least a portion of a perimeter of the opening, and the ring circumscribes the spout; and
the body of the overcap comprises an inner wall and an outer wall that circumscribe the plug, and both the inner wall and the outer wall abut at least a portion of the first surface when the overcap is in the closed position, and the ring does not abut the inner wall when the overcap is in the closed position wherein the plane of the overcap is perpendicular to both the inner wall and the outer wall of the overcap.

2. The closure of claim 1 , wherein the ring is perpendicular to the plane of the base.

3. The closure of claim 1 , wherein the base comprises a connecting wall configured to connect the base to the container, and the connecting wall is configured to extend from an opposite side of the first surface relative to the ring.

4. The closure of claim 3 , wherein the base comprises a skirt that circumscribes the connecting wall.

5. The closure of claim 3 , wherein the connecting wall comprises threads.

6. The closure of claim 1 , wherein an end of the plug opposite from the body of the overcap is a tapered end such that a diameter of the end of the plug opposite from the body has a diameter smaller than a diameter of a section of the plug between the tapered end and the body, and an aperture is provided within the plug.

7. The closure of claim 1 , wherein the angle defined by the plane of the overcap and the plane of the base is about 135 degrees when the overcap is in the open position.

8. A package comprising:
a container housing a liquid; and
a closure comprising
a base comprising a first surface comprising an opening, the base connected to the container such that the liquid in the container is pourable from the container through the opening, and the first surface defines a plane of the base;
an overcap comprising a body and a plug, the plug is sized and shaped to seal the opening when the overcap is in a closed position relative to the base, wherein the body defines a plane of the overcap, wherein the plane of the overcap extends through the top surface of the overcap when the overcap is in the closed position, and the plug extends from the body in a main extension direction to which the plane of the overcap is perpendicular; and
a hinge configured to connect the overcap to the base, the hinge is biased to maintain an open position of the overcap relative to the base, and the hinge is configured such that the plane of the overcap and the plane of the base define an angle of 125 degrees to 145 degrees when the overcap is in the open position;

the first surface of the base further comprises a ring configured to retain a portion of the liquid on a section of the first surface that is within the ring, the base comprises a spout extending from the first surface along at least a portion of a perimeter of the opening, and the ring circumscribes the spout; and
the body of the overcap comprises an inner wall and an outer wall that circumscribe the plug, and both the inner wall and the outer wall abut at least a portion of the first surface when the overcap is in the closed position, and the ring does not abut the inner wall when the overcap is in the closed position wherein the plane of the overcap is perpendicular to both the inner wall and the outer wall of the overcap.

9. The package of claim 8 wherein the liquid is a coffee creamer.
