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 a first end having a generally flat surface that is provided at an angle to the top surface of the lid base, a second end adapted to receive a straw, and a drink aperture therethrough. 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. The protrusion has a seal surface at an angle to the top wall to seal against the first end of the mouthpiece to close 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 having a top surface and a sidewall extending downwardly therefrom, the lid base having a mouthpiece aperture and a vent aperture;
a pliable mouthpiece connected to the lid base adjacent the mouthpiece aperture, the mouthpiece being curved toward a front of the beverage container adjacent a first end of the mouthpiece, the mouthpiece having a second end that is adapted to receive a straw that is located within the beverage container, the mouthpiece having a groove between the first end and the second end to assist in seating the mouthpiece to the lid base, a drink aperture extending through the mouthpiece from the first end to the second end thereof, and the first end of the mouthpiece having a flat surface that is provided in a plane at an angle to the top surface of the lid base;
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 from the sidewall, 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, wherein the protrusion in the lid dome has a seal surface at an angle to the top wall that operates to seal against the first end of the mouthpiece to close 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 secure 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 top wall of the lid dome extends at an angle to the top surface of the lid base and is transverse to the seal surface of the lid dome.

3. The lid assembly of claim 1 , wherein the seal surface of the protrusion is elliptical, and wherein the mouthpiece at the first end thereof is elliptical.

4. 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 the pushbutton activator in the lock position to prevent the pushbutton activator from being pushed in to release the lid dome.

5. A lid assembly for a beverage container, comprising:
a lid base;
a pliable mouthpiece connected to the lid base, the mouthpiece having a first end distal the lid base, a second end that is adapted to receive a straw that is located within the beverage container, a drink aperture extending through the mouthpiece from the first end to the second end thereof, and the first end of the mouthpiece having a flat surface that is provided in a plane at an angle to the top surface of the lid base; and,
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, wherein the lid dome has a protrusion that extends from an inner surface of the top wall of the lid dome, wherein the protrusion has a seal surface at an angle to the top wall that operates to seal against the first end of the mouthpiece to close the drink aperture when the lid dome is in the closed position.

6. The lid assembly of claim 5 , wherein the protrusion of the lid dome extends from an inner surface of the top wall of the lid dome at an angle to the top wall.

7. The lid assembly of claim 5 , wherein the lid dome has a tang extending downwardly from the sidewall in a direction opposite the top wall, and wherein the tang has an aperture therethrough.

8. The lid assembly of claim 7 , wherein the lid base has a fastening opening for receiving the tang of the lid dome, and a pushbutton activator, and wherein the pushbutton activator engages the aperture in the tang when the lid dome is in the closed position.

9. The lid assembly of claim 8 , wherein the pushbutton activator has a projection that engages the aperture in the tang when the lid dome is in the closed position to secure 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.

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

11. The lid assembly of claim 5 , 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.

12. The lid assembly of claim 5 , further comprising a lock member that transitions between a lock position and an unlock position, and wherein the lid base has a lock aperture to provide access to the lock member.

13. The lid assembly of claim 12 , 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.

14. The lid assembly of claim 5 , wherein the top wall of the lid dome extends at an angle to a top surface of the lid base.

15. The lid assembly of claim 5 , wherein the shape of the seal surface of the protrusion is elliptical, and wherein the mouthpiece at the first end thereof is generally elliptical.

16. The lid assembly of claim 5 , wherein the lid base and the lid dome are made of a hard rigid plastic, and wherein the mouthpiece is made of a pliable material.

17. A lid assembly for a beverage container, comprising:
a lid base having a top surface and a sidewall extending downwardly therefrom;
a mouthpiece having a first end distal the lid base, a second end that is adapted to receive a straw that is located within the beverage container, a drink aperture extending through the mouthpiece from the first end to the second end thereof, and the first end of the mouthpiece having a flat surface that is provided in a plane at an angle to the top surface of the lid base;
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, wherein the lid dome has a protrusion that extends from an inner surface of the top wall of the lid dome, wherein the protrusion has a seal surface at an angle to the top wall that operates to seal against the first end of the mouthpiece to close the drink aperture when the lid dome is in
the closed position, and wherein the protrusion mates with and is seated against the first end of the mouthpiece 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 secure the lid dome in the closed position, and wherein the pushbutton activator releases the ta
