Abstract: A beverage container assembly including a first beverage container having a first vessel body that has a first base having a first perimeter and a first side wall connected to the first base, wherein the first side wall includes a connecting member. The first beverage container including a first rim defined on the first side wall distal to the first base. The assembly further including a second beverage container that includes a second vessel body that has a second base having a second perimeter and a second side wall connected to the second base. The second side wall includes an engagement member that engages with the connecting member so that the first beverage container is attached to the second beverage container.

Abstract: An assembly that includes a first container having a first vessel body that includes: a first base having a first perimeter, a first side wall connected to the first base, and a first rim defined on the first side wall distal to the first base. The first container includes a cap that releasably engages the first rim. The assembly includes a second container having a second vessel body that includes: a second base having a second perimeter, a second side wall connected to the second base, and a second rim defined on the second side wall distal to the second base, wherein the cap of the first container is releasably engaged by the second base of the second container such that the cap is interposed between the first rim of the first container and the second base of the second container.

Abstract: A beverage container assembly including a first beverage container having a first vessel body that has a first base. The first beverage container including a first rim defined on a first side wall distal to the first base. The first base has a convex shape in a central portion of the base. The first vessel body further including an edge connected to the first rim, wherein the edge lies entirely in a first plane that does not intersect a second plane that contains a free end of the first rim. The assembly further including a second beverage container defining a detent. The second beverage container including a second rim defined on a second side wall distal to the second base, wherein the edge is releasably and directly engaged by the detent of the second base such that the first beverage container is releasably engaged by the second beverage container.

Abstract: A gas dissolving apparatus that combines a gas at first pressure into a working fluid, the working present at a second pressure equal to or greater than the first pressure. The device includes a molecular mixing chamber which is designed as a truncated conical chamber located between an inlet and an outlet. The device can include a plurality of inlets for the gas to enter into the mixing section, and a plurality of passages through the truncated conical chamber. The truncated conical chamber is surrounded by a cylindrical chamber leading to the outlet of the chamber.
