Jasper County Democrat, Volume 9, Number 14, Rensselaer, Jasper County, 7 July 1906 — Handy Preserving Jar. [ARTICLE+ILLUSTRATION]

Handy Preserving Jar.

In the illustration is shown a jar the upper end of which Is formed with a flange. ui>on which rests a cap so shaped as to form a tight connection. Around the edge of the cap Is a rubber gasket. The center of the cap is formed with a small vent, closed by means of a rubber valve. A vacuum or partial vacuum can be created by bringing the contents to a boiling temperature, which will cause the outside atmos-

pberic pressure to tightly close the rubber valve in the cap, or the air at the top of the vessel can be exhausted by means of a pump. In the latter event the invention can be used for preserving materials without cooking. This invention is adapted to the use of any other material than glass for Jars, and the form Is not necessarily limited to that Indicated In the drawing. Both the Jar and the cover are made entirely of glass, making it nonpolsonous, with the advantage that it can be used again and again.
