Abstract

A lid assembly for a beverage container is provided. The lid assembly has a lid base, a mouthpiece and a lid dome. The mouthpiece is connected to the lid base and has an extended annular member with a first end and a drink aperture extending through a center of the annular member. The lid dome is pivotally connected to the lid base and pivots between an open position and a closed position. The lid dome has a protrusion that extends from an inner surface of the lid dome, and a seal surface that operates to seal against the first end of the annular member of the mouthpiece to close the drink aperture when the lid dome is in the closed position. The protrusion is generally seated within the drink aperture when the lid dome is in the closed position.

First claim

What is claimed is:

1. A lid assembly for a beverage container,
comprising: a lid base;
a pliable mouthpiece connected to the lid base, the mouthpiece having an extended annular member with a first end and a flange at a second end of the annular member, a drink aperture extending through a center of the annular member from the first end to the second end;
a lid dome pivotally connected to the lid base, the lid dome pivoting between an open position and a closed position, the lid dome having a top wall and a sidewall extending therefrom, and a tang extending downwardly away from the sidewall in a direction opposite the top wall, the tang having an aperture therethrough, wherein the lid dome has a protrusion that extends from an inner surface of the top wall of the lid dome and is co-planar with the top wall, wherein the lid dome has a seal surface that operates to seal against the first end of the annular member of the mouthpiece to close the drink aperture when the lid dome is in the closed position, and wherein the protrusion is generally positioned within the drink aperture when the lid dome is in the closed position; and,
wherein the lid base has a fastening opening for receiving the tang of the lid dome, wherein the lid base has a pushbutton activator adjacent the fastening opening, the pushbutton activator having a projection that engages the aperture in the tang when the lid dome is in the closed position to lock the lid dome in the closed position, the projection releasing the tang when the pushbutton activator is pushed in by a user to allow the lid dome to be transitioned to the open position.

2. The lid assembly of claim 1 , wherein the protrusion is circular, and wherein an external circumference of the protrusion mates with an inner diameter of the first end of the annular member.

3. The lid assembly of claim 1 , further comprising a lock member that moves within an annular opening in the lid base from a lock position to an unlock position, wherein the lid base has a lock aperture to provide access to the lock member, and wherein the lock member engages a pushbutton activator in the lock position to prevent the pushbutton activator from being pushed in to release the lid dome.

4. A lid assembly for a beverage container, comprising:
a lid base;
a mouthpiece connected to the lid base, the mouthpiece having an extended annular member with a first end and a flange at a second end of the annular member, a drink aperture extending through a center of the annular member from the first end to the second end;
a lid dome pivotally connected to the lid base, the lid dome pivoting between an open position and a closed position, the lid dome having a protrusion that extends from an inner surface of the lid dome, wherein the lid dome has a seal surface that operates to seal against the first end of the annular member of the mouthpiece to close the drink aperture when the lid dome is in the closed position, and wherein the protrusion is generally seated within the drink aperture when the lid dome is in the closed position; and,
a lock member that transitions between a lock position and an unlock position, wherein the lid base has a lock aperture to provide access to the lock member, wherein the lid dome has a top wall and a sidewall extending therefrom, and a tang extending downwardly away from the sidewall in a direction opposite the top wall, wherein the tang has an aperture therethrough, wherein the lid base has a fastening opening for receiving the tang of the lid dome, and a pushbutton activator, wherein the pushbutton activator engages the aperture in the tang when the lid dome is in the closed position, wherein the pushbutton activator has a projection that engages the aperture in the tang when the lid dome is in the closed position to lock the lid dome in the closed position, and wherein the projection releases the tang when the pushbutton activator is pushed in by a user to allow the lid dome to be transitioned to the open position.

5. The lid assembly of claim 4 , further comprising a spring member connected to the lid dome to bias the lid dome to the open position.

6. The lid assembly of claim 4 , wherein the lid dome has a top wall and a sidewall extending therefrom, and wherein the lid base has a top wall, a sidewall, and a step between the top wall and the sidewall for seating the sidewall of the lid dome.

7. The lid assembly of claim 4 , wherein the lock member moves within an annular opening in the lid base from the lock position to the unlock position, and wherein the lock member engages a pushbutton activator in the lock position to prevent the pushbutton activator from being pushed in to release the lid dome.

8. The lid assembly of claim 4 , wherein the protrusion is circular.

9. The lid assembly of claim 4 , wherein an external circumference of the protrusion mates with an inner diameter of the first end of the annular member.

10. The lid assembly of claim 4 , wherein the annular member has a generally flat top surface, and wherein a top wall of the lid dome has a mating generally flat top surface.

11. The lid assembly of claim 4 , wherein the annular member has a sloped top surface, and wherein a top wall of the lid dome has a mating sloped top surface.

12. The lid assembly of claim 4 , wherein the lid base and the lid dome are made of a generally hard rigid plastic, and wherein the mouthpiece is made of a pliable material.

13. A lid assembly for a beverage container,
comprising: a lid base;
a mouthpiece connected to the lid base, the mouthpiece having a first end and a second end, and an extended annular member therebetween, a drink aperture extending through a center of the annular member from the first end to the second end;
a lid dome pivotally connected to the lid base, the lid dome pivoting between an open position and a closed position, wherein the lid dome has a top wall and a sidewall extending therefrom, and a tang extending downwardly away from the sidewall in a direction opposite the top wall, wherein the lid dome has a protrusion that extends from an inner surface of the top wall of the lid dome, wherein the lid dome has a seal surface that operates to seal against the first end of the annular member of the mouthpiece to close the drink aperture when the lid dome is in the closed position, and wherein the protrusion generally mates with and is generally seated within the drink aperture when the lid dome is in the closed position; and,
wherein the lid base has a fastening opening for receiving the tang of the lid dome, wherein the lid base has a pushbutton activator adjacent the fastening opening, wherein the pushbutton activator engages the tang when the lid dome is in the closed position to lock the lid dome in the closed position, and wherein the pushbutton activator releases the tang when the pushbutton activator is pushed in by a user to allow the lid dome to be transitioned to the open position.

14. The lid assembly of claim 13 , wherein the tang has an opening, and wherein pushbutton activator has a projection that engages an opening in the tang when the lid dome is in the closed position to releasably secure the lid dome in the closed position.

15. The lid assembly of claim 13 , wherein the extended annular member of the mouthpiece is tubular in shape.

16. The lid assembly of claim 13 , wherein the lid dome compresses the mouthpiece in the closed position.
