Mixing container and method of filling
First Claim
1. A mixing container comprising:
- an outer vessel having a bottom, an open mouth and a peripheral sidewall between the open mouth and the bottom;
an inner vessel having an end, an open mouth and a peripheral sidewall between the end and the open mouth;
a seal; and
a closure positionable to close the open mouth of the outer vessel and form an exterior seal between the closure and open mouth of the outer vessel, the closure being attached to the end of the inner vessel, the closure and inner vessel being rigidly fixed to one another;
wherein the open mouth of the inner vessel is biased against a portion of the seal that is disposed between the open mouth of the inner vessel and the bottom of the outer vessel to effectuate an interior seal between the inner and outer vessels when the closure is positioned to close the open mouth of the outer vessel; and
wherein breaking of the exterior seal between the closure and the open mouth of the outer vessel breaks the interior seal between the inner and outer vessels.

Abstract
A mixing container having an outer vessel with an open mouth and an inner vessel also with an open mouth separately stores two liquids for automatic mixing when the container is opened. Upon assembly, an interior seal between the open mouth of the inner vessel and the bottom of the outer vessel is effected through placement of a closure in the open mouth of the outer vessel. The inner vessel is received by a socket mounted in the closure which provides a resilient bias on the inner vessel to force the open mouth of the inner vessel against the bottom. A method for filling the mixing container includes a filling of the inner vessel, placement of the outer vessel over the inner vessel, immersing at least the open mouth of the outer vessel into a second liquid and evacuating the outer vessel. The mixing container may then be closed to resiliently bias the open mouth of the inner vessel against the bottom of the outer vessel to effect the interior seal.

12. A mixing container comprising:
-
an outer vessel having a bottom, an open mouth and a peripheral sidewall between the open mouth and the bottom; an inner vessel having an end, an open mouth having an edge and a peripheral sidewall between the end and the open mouth; and a closure positionable to close the open mouth of the outer vessel and form an exterior seal between the closure and the open mouth of the outer vessel; wherein the open mouth of the inner vessel is resiliently biased downwardly towards the bottom of the outer vessel to effect an interior seal when the mixing container is assembled; and wherein breaking of the exterior seal between the closure and the open mouth of the outer vessel breaks the interior seal between the inner and outer vessels. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
