Abstract

A beverage carafe comprises a beverage reservoir and a channel for directing a flow of liquid from the reservoir when the carafe is tilted for dispensing the liquid. The channel has a floor and an elongated protrusion projecting upward from the floor. The protrusion is transverse to the flow of the liquid through the channel and has a curved distal face and curved sides.

First claim

That which is claimed:

1. A beverage carafe comprising:
a beverage reservoir;
a channel for directing a flow of liquid from the reservoir when the carafe is tilted for dispensing the liquid, the channel having a floor and an elongated protrusion projecting upward from the floor, the protrusion being transverse to the flow of the liquid through the channel and having a curved distal face and curved sides;
a throat positioned such that the liquid flows from the reservoir through the throat to the channel;
a flapper that pivots between a down position in which the throat is at least partly closed off and an up position for dispensing, the flapper having a concave bottom surface to direct the flow of the liquid toward the channel; and
wherein the throat has opposing flat side edges such that opposing vent openings are defined between the concave bottom surface of the flapper and the flat side edges of the throat when the flapper is in the down position.

2. The beverage carafe of claim 1 , further comprising a pour spout;
wherein the channel directs the flow of the liquid from the reservoir to the pour spout.

3. The beverage carafe of claim 1 , further comprising a selectively removable lid for selectively closing off an open top end of the reservoir;
wherein the channel is defined in the lid.

4. A beverage carafe comprising:
a beverage reservoir;
a channel for directing a flow of liquid from the reservoir when the carafe is tilted for dispensing the liquid;
a throat positioned such that the liquid flows from the reservoir through the throat to the channel; and
a flapper that pivots between a down position in which the throat is at least partly closed off and an up position for dispensing, the flapper having a concave bottom surface to direct the flow of the liquid toward the channel.

5. The beverage carafe of claim 4 , wherein the throat has opposing flat side edges such that opposing vent openings are defined between the concave bottom surface of the flapper and the flat side edges of the throat when the flapper is in the down position.

6. The beverage carafe of claim 4 , wherein the channel has a floor and an elongated protrusion projecting upward from the floor, the protrusion being transverse to the flow of the liquid through the channel and having a curved distal face and curved sides.

7. The beverage carafe of claim 4 , further comprising a pour spout;
wherein the channel directs the flow of the liquid from the reservoir to the pour spout.

8. The beverage carafe of claim 4 , further comprising a selectively removable lid for selectively closing off an open top end of the reservoir;
wherein the channel is defined in the lid.
