Abstract

A container assembly suitable for holding pressurized content includes a plastic container and a base cup. The plastic container may include a including a rounded base portion, and the base cup may be connected to the container and configured to support the plastic container. In embodiments the plastic container and the base cup are comprised of plastic, and may be comprised of substantially the same recyclable plastic material. In embodiments, the base cup may be thermoformed, and/or the container assembly may be comprised of 80% or more, by weight, of PET.

What is claimed is:
