PepsiCo solves post-fill carbonation challenges

PepsiCo solves post-fill carbonation challenges

This patent assigned to PepsiCo, Purchase, NY, solves a production challenge to produce carbonated soft drinks (CSDs) and other beverages by inducing carbonation after filling. One obvious way to carbonate a liquid is to add solid carbon dioxide, but that presents problems—including but not limited to container deformation—that the patent addresses.

In one method, after adding solid carbon dioxide and sealing the container, the development of overpressure is limited through the use of an adsorber material—such as activated carbon—that is included in the applied closure.

Alternately, in-line agitation done at 150 to 200 oscillations per minute for at least 2½ minutes can be used to control the overpressure from the added CO2. The filing indicates that standard production equipment such as vibratory conveyors can be used to provide the needed agitation.
