Pour cap for fluid containers having open or closed position communication structure with sound and visual features

1. A cap for a container adapted to contain a fluid comprising:

a cap body configured for attachment to a neck of the container having at least one pour opening through which the fluid can be poured from the container, the cap body moveable by rotation on the neck of the container to an open position or to a closed position and;

a gasket attached to the cap body having a fluid flow opening, a first portion configured to form a first seal on the cap body, and a second portion configured to form a second seal on an inside diameter or a top surface of the neck of the container, the gasket configured for compression by the cap body in the closed position to form a third seal on a top surface of the neck of the container, the gasket configured to form a fluid flow passage in the open position allowing fluid flow from the container through the fluid flow opening in the gasket to the at least one pour opening in the cap body while maintaining the first seal and the second seal; and

an open or closed position communication structure configured to indicate the open position or the closed position to a user of the cap, the structure comprising a rib on the gasket and a mating detent on the cap body for producing a clicking sensation upon manipulation of the cap body by the user,

wherein the cap body includes a shelf wherein the gasket rests having a height selected to produce the clicking sensation.

2. The cap of claim 1 wherein the gasket is configured to deform in reaction to positional interference between the rib and the detent during movement of the cap body causing the clicking sensation.

3. A cap for a container adapted to contain a fluid comprising:

a cap body configured for attachment to a neck of the container having at least one pour opening through which the fluid can be poured from the container, the cap body moveable by rotation on the neck of the container to an open position or to a closed position and;

a gasket attached to the cap body having a fluid flow opening, a first portion configured to form a first seal on the cap body, and a second portion configured to form a second seal on an inside diameter or a top surface of the neck of the container, the gasket configured for compression by the cap body in the closed position to form a third seal on a top surface of the neck of the container, the gasket configured to form a fluid flow passage in the open position allowing fluid flow from the container through the fluid flow opening in the gasket to the at least one pour opening in the cap body while maintaining the first seal and the second seal; and

an open or closed position communication structure configured to indicate the open position or the closed position to a user of the cap, the structure comprising a rib on the gasket and a mating detent on the cap body for producing a clicking sensation upon manipulation of the cap body by the user,

wherein the cap body comprises a transparent material and further comprising at least one visual feature on the cap body viewable by the user in the open position, the visual feature comprising at least one color patch that matches a color of the gasket, or a marking that contrasts with a textured background on the cap body.

4. A cap for a container adapted to contain a fluid comprising:

a cap body configured for attachment to a neck of the container having at least one pour opening through which the fluid can be poured from the container, the cap body moveable by rotation on the neck of the container to an open position or to a closed position and;

a gasket attached to the cap body having a fluid flow opening, a first portion configured to form a first seal on the cap body, and a second portion configured to form a second seal on an inside diameter or a top surface of the neck of the container, the gasket configured for compression by the cap body in the closed position to form a third seal on a top surface of the neck of the container, the gasket configured to form a fluid flow passage in the open position allowing fluid flow from the container through the fluid flow opening in gasket to the at least one pour opening in the cap body while maintaining the first seal and the second seal; and

an open or closed position communication structure configured to indicate the open position or the closed position to a user of the cap, the structure comprising a rib on the gasket and a mating detent on the cap body for producing a clicking sensation upon manipulation of the cap body by the user,

wherein the second portion of the gasket has an inwardly tapered surface configured to facilitate compression of the gasket in the closed position.

5. A cap for a container adapted to contain a fluid having a threaded neck comprising:

a cap body comprising a transparent material having at least one pour opening through which the fluid can be poured from the container and a plurality of threads configured for mating engagement with the threaded neck of the container to place the cap in an open position or in a closed position;

a gasket attached to the cap body having a first portion configured to form a first low pressure seal on the cap body, a sealing surface configured for compression by the cap body to seal the container in the closed position with a high pressure seal and for return to an undeformed state to form a fluid flow passage in the open position, an o-ring feature configured to seat in an inside diameter of the threaded neck to form a second low pressure seal, and a fluid flow opening configured to allow fluid flow through the gasket to the fluid flow passage and the at least one pour opening in the open position; and

an open or closed position communication structure configured to indicate the open position or the closed position to a user of the cap, the structure comprising at least one visual feature on the cap body viewable by the user in the open position, the visual feature comprising a marking that contrasts with a textured background on the cap body.

6. The cap of claim 5 wherein the threads are formed on an inside surface of the cap body.

7. The cap of claim 5 wherein the threads are contained on a threaded ring mounted on the cap body.

8. The cap of claim 5 further comprising a rib on the gasket and a mating detent on the cap body for producing a clicking sensation upon manipulation of the cap body by the user.

9. A cap for a container adapted to contain a fluid having a threaded neck comprising:

a cap body comprising a transparent material having at least one pour opening through which the fluid can be poured from the container and a plurality of threads configured for mating engagement with the threaded neck of the container to place the cap in an open position or in a closed position;

a gasket attached to the cap body having a first portion configured to form a first low pressure seal on the cap body, a sealing surface configured for compression by the cap body to seal the container in the closed position with a high pressure seal and for return to an undeformed state to form a fluid flow passage in the open position, an o-ring feature configured to seat in an inside diameter of the threaded neck to form a second low pressure seal, and a fluid flow opening configured to allow fluid flow through the gasket to the fluid flow passage and the at least one pour opening in the open position;

an open or closed position communication structure configured to indicate the open position or the closed position to a user of the cap, the structure comprising at least one visual feature on the cap body viewable by the user in the open position,

wherein the visual feature comprises at least one color patch that matches a color of the gasket.

10. The cap of claim 9 wherein the sealing surface of the gasket comprises an inwardly tapered surface configured to facilitate compression of the gasket in the closed position.
