Title:
COMPACT PRESERVATION AND REFRIGERATION SYSTEM FOR PERISHABLE SUBSTANCES
Document Type and Number:
WIPO Patent Application WO2004066749
Kind Code:
A9
Abstract:
A device for storage of an opened food container. The device includes a housing for receiving the opened food container. A poppet valve assembly is provided for insertion in an opening in the opened food container and biased to enable it to accommodate opened food containers of varying sizes. The device includes a pressurized source of inert gas located within the housing, a regulator for reducing the pressure of the inert gas at the poppet valve assembly. The poppet valve assembly also includes a spring-loaded check ball, low-pass port, shuttle and orifice to control pressure and flow path of the heavier-than-air inert gas and to direct the inert gas to the opened food container thus displacing any air that may have been present therein through an exhaust port.
