Abstract

A container lid including: a lid body which includes a flared perimeter wall, an inner structure, and a perimeter well. The inner structure defines a central throat. The perimeter well defines a plurality of openings disposed around the central throat. A lid body seal is disposed about the lid body. A lid upper includes: a lid base and a lid roof secured to the lid base. The lid base is lockably received in the central throat. The lid roof at least partially covers the perimeter well when the lid base is lockably secured in the central throat.

First claim

The invention claimed is:

1. A container lid comprising:
a lid body comprising a flared perimeter wall, an inner structure, and a perimeter well,
wherein the perimeter well is at least partially defined by an inner surface of the flared perimeter wall, the flared perimeter wall having a first end and an opposite second end, the first end and the second end defining a longitudinal axis;
wherein the inner structure defines a central throat, an outer circumferential surface of the central throat being radially spaced from the inner surface of the flared perimeter wall;
wherein the central throat defines an aperture extending through the lid body, and
wherein the perimeter well defines a plurality of openings disposed around the central throat;

a lid body seal disposed about the lid body; and
a lid upper comprising:
a lid base; and
a lid roof secured to the lid base, wherein the lid base is lockably received within the aperture of the central throat, at an inner circumferential surface of the central throat,
wherein when the lid base is lockably secured in the aperture of the central throat, the lid roof partially covers the perimeter well,
wherein a bottom surface of the perimeter well pitches downward from the inner structure towards the flared perimeter wall,
wherein the plurality of openings are defined by the perimeter well proximate a lowermost extent of the perimeter well,
wherein the lid body further comprises an inner shelf projecting inward from the flared perimeter wall towards the perimeter well,
wherein the lid roof comprises an outer perimeter disposed at least partially above the inner shelf,
wherein an underside of the lid roof is concave,
wherein an apex of the lid roof is disposed below an upper extent of the lid body,
wherein the lid roof is separated from the inner shelf by a gap, the gap fully extending circumferentially around the longitudinal axis,
wherein the lid roof is spaced from the well wall such that a splash chamber is defined thereby, the splash chamber fully extending circumferentially around the longitudinal axis,
wherein an inlet to the splash chamber is defined by the plurality of openings and an outlet for the splash chamber is defined by the gap,
wherein a nonlinear flow path is defined through the splash chamber, and
wherein the liquid flow path is always open, and the gap is not covered.

2. The container lid of claim 1 , wherein the central throat defines the inner circumferential surface of the aperture defined by the central throat, the inner circumferential surface comprising a plurality of locking channels, and wherein the lid base comprises a plurality of bayonets extending into the plurality of locking channels when the lid base is lockably secured in the central throat.

3. The container lid of claim 2 , further comprising a thumbturn extending from a bottom of the lid base.

4. The container lid of claim 1 , wherein the lid base is rotatably secured in the central throat.

5. A container lid comprising:
a lid body including:
a substantially cylindrical outer side wall having a first end and an opposite second end, the first end and the second end defining a longitudinal axis;
a central throat disposed within the outer side wall and spaced radially apart therefrom, wherein the central throat defines an aperture extending through the lid body; and
a well wall extending between the outer side wall at the second end and the central throat, the well wall at least partially defining a plurality of openings spaced circumferentially around the longitudinal axis; and
a lid upper configured to be releasably secured to the lid body, the lid upper including:
a lid base configured to lockably mate within the aperture of the central throat, at an inner circumferential surface of the central throat; and
a lid roof coupled to the lid base, the lid roof having a perimeter diameter, wherein when the lid base is secured within the central throat, the perimeter diameter is such that the lid roof partially covers the plurality of openings,

wherein the outer side wall includes an inner shelf disposed between the first end and the second end, the inner shelf disposed at least partially underneath the lid roof when the lid upper is secured to the lid body,
wherein the lid roof is separated from the inner shelf by a gap, the gap fully extending circumferentially around the longitudinal axis,
wherein the central throat is spaced from the second end of the outer side wall such that an underside surface of the well wall is concave,
wherein an underside of the lid roof is concave,
wherein an apex of the lid roof is disposed below an upper extent of the lid body,
wherein the plurality of openings are defined by the well wall proximate a lowermost extent of the well wall,
wherein when the lid upper is secured to the lid body, the lid roof is spaced from the well wall such that a splash chamber is defined thereby, the splash chamber fully extends circumferentially around the longitudinal axis,
wherein an inlet to the splash chamber is defined by the plurality of openings and an outlet for the splash chamber is defined by the gap,
wherein a nonlinear flow path is defined through the splash chamber, and
wherein the liquid flow path is always open, and the gap is not covered.

6. The container lid of claim 5 , wherein the lid upper further includes a gasket disposed at least partially between the lid base and the lid roof.

7. The container lid of claim 5 , wherein the lid base lockably mates with the throat via a bayonet connection at the inner circumferential surface of the central throat.

8. The container lid of claim 7 , wherein the lid base includes one or more bayonets and the throat includes one or more corresponding locking channels.

9. The container lid of claim 7 , wherein the lid upper is at least partially rotatable around the longitudinal axis to lock the bayonet connection.

10. A beverage container comprising:
a container body; and
a container lid, the container lid configured to removable couple to the container body, the container lid including:
a lid body having a flared perimeter wall, the flared perimeter wall having an inner surface, the flared perimeter wall having a first end and an opposite second end, the first end and the second end defining a longitudinal axis;
a central throat disposed within the flared perimeter wall, an outer circumferential surface of the central throat being radially spaced apart from the inner surface of the flared perimeter wall, wherein the central throat defines an aperture extending through the lid body, and
a perimeter well extending between the flared perimeter wall and the central throat, the perimeter well at least partially defining a plurality of openings disposed around the central throat, the perimeter well being at least partially defined by the inner surface of the flared perimeter wall;
a seal disposed around an exterior of the lid body, the seal configured to engage with the container body; and
a lid upper having a lid base and a lid roof, the lid upper configured to releasably secure to the lid body such that the lid roof partially covers the perimeter well,
wherein when the lid upper is secured to the lid body, the lid roof is spaced from the perimeter well such that a splash chamber is defined, the splash chamber fully extending circumferentially around the longitudinal axis,

wherein the lid base is configured to lockably mate within the aperture of the central throat, at an inner circumferential surface of the central throat,
wherein a bottom surface of the perimeter well pitches downward from the inner structure towards the flared perimeter wall,
wherein the plurality of openin
