Abstract

Systems and devices for creating an infused liquid, for example using tea leaves, including a vessel having a base and a wall extending up from the base to a first height, wherein an interior surface of the wall defines a substantially cylindrical internal volume having a first diameter and substantially the first height and an exterior surface of the wall has a second diameter at an upper extent of the wall and a third diameter proximate to the base, wherein the third diameter is greater than the second diameter and the exterior surface of the wall gradually increases in diameter from the second diameter to the third diameter. The first height may be less than the first diameter. The vessel may have a spout and handle. The systems and devices may comprise a lid for the vessel, a plunger through the lid, and a strainer assembly coupled with the plunger.

Dependent claims

A system for creating an infused liquid, comprising:

a vessel having a base and a wall extending upwardly from the base to a first height, wherein:
an interior surface of the wall is substantially vertical and defines a cylindrical internal volume having a first diameter and substantially the first height;
the vessel comprises a spout at an upper portion of the wall;
the vessel comprises a handle on an exterior surface of the wall;
and
an exterior surface of the wall has a second diameter substantially at an upper extent of the wall and a third diameter proximate to the base, wherein:
the third diameter is greater than the second diameter;
and
the exterior surface of the wall gradually increases in diameter from the second diameter to the third diameter;
a strainer assembly comprising a mesh filter, wherein the strainer assembly is configured to be inserted within the internal volume and wherein a diameter of the mesh filter is configured to be received by the internal volume;
a plunger rod having a first end and a second end, wherein the first end is coupled with the strainer assembly;
and
a lid configured to removably couple with the wall near the upper extent of the wall, wherein the lid comprises an opening slidably coupled with the plunger rod.
