A container including a finish defining an opening at a first end of the container that provides access to an internal volume defined by the container. A base portion of the container includes a diaphragm that is concave relative to an exterior of the container. The diaphragm extends from a standing surface of the container to a center push-up portion of the base portion. The standing surface is at a second end of the container opposite to the first end. The diagram is configured to move from an as-blown first configuration to a second configuration in which the diaphragm is closer to the first end as compared to the first configuration in order to reduce residual vacuum within the container. The diaphragm is generally hemispherical in cross-section when in the second configuration.

The present disclosure relates to a container base including a hemispherical actuating diaphragm.
This section provides background information related to the present disclosure, which is not necessarily prior art.
As a result of environmental and other concerns, plastic containers, more specifically polyester and even more specifically polyethylene terephthalate (PET) containers, are now being used more than ever to package numerous commodities previously supplied in glass containers. Manufacturers and fillers, as well as consumers, have recognized that PET containers are lightweight, inexpensive, recyclable and manufacturable in large quantities.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
FIG. 1 is a side view of a container according to the present teachings;
FIG. 2A is a perspective view of an exemplary container base according to the present teachings;
Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.
Example embodiments will now be described more fully with reference to the accompanying drawings.
With initial reference to FIG. 1, a container according to the present teachings is generally illustrated at reference numeral 10. The container 10 can be any suitable container having any suitable size and shape. For example, the container 10 can be a generally round bottle, and can be configured to be filled with 20 ounces of a commodity.
