Benefits of technology

The patent is about a solution for storing liquids in containers that minimize the presence of oxygen and other atmospheric gases. The solution is a lid that forms an airtight seal with the container and purges the atmospheric gases out of the container during the installation process. The lid accommodates thermal expansion and contraction of the stored fluid, allowing for a range of fill levels of the container, and also lowers the fluid level when the seal between the lid and the container is broken. The technical effects of this solution include improved storage and preservation of liquids, reduced risk of contamination, and better safety during handling and transportation.

Problems solved by technology

Many production and distribution companies are striving to develop more complex and sophisticated packaging mechanisms for securing consumable liquids, such as wine and other beverages.

Embodiment Construction

[0040]Many liquids spoil over time when exposed to oxygen and / or other atmospheric gases, and therefore, must be stored in airtight storage containers that minimize the presence of oxygen and other atmospheric gases. For example, during the aging of wine, if a wine is not protected from both microbial spoilage and oxygen at all times it is likely to spoil. Protecting wine usually involves maintaining proper sulfur dioxide (SO2) levels and keeping containers full. Typically, containers for fluids, that are to be protected from atmospheric gases, maintain a space between the top surface of a stored fluid and the underside of the lid of the container (e.g., headspace) at a reduced pressure with respect to the container's ambient environment. This air space (e.g., headspace) must be maintained to accommodate thermal expansion of the fluid to prevent the lid from being blown off of the container, or to prevent the container from rupturing.

Abstract

A lid, having an opening area encased by one of the variety of shaped sidewalls with a flexible ribbed portion extending downwardly to one of the variety of shaped bases is provided for completely purging of atmospheric gases out of a container upon installation so as to eliminate head space by forming an airtight barrier with the container and the lid. A lid rim, having an inside portion connected to the top of the one of the variety of shaped with the flexible ribbed portion and an outside portion is provided for seating the lid to the container. The dome shaped base is connected to the bottom of the one of the variety of shaped side walls forming a circular base of the lid.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application is a Continuation-in-Part (CIP) related to and claims priority from pending non-provisional U.S. patent application Ser. No. 13 / 545,481 filed Jul. 10, 2012 which application is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates in general to a container lid, and more particularly to a lid device for purging air of out of a container holding a liquid.DESCRIPTION OF THE RELATED ART[0003]Many production and distribution companies are striving to develop more complex and sophisticated packaging mechanisms for securing consumable liquids, such as wine and other beverages. Many of these packaged beverages to be sold and distributed throughout the world need a greater shelf life. Certain beverages, such as wine, require the consumable liquid be protected from atmospheric gases to preserve the inherent qualities and characteristics of the wine. As such, a need exists for an air purgin...
