CANNING
NEEDS ASSURED
WPB Promises
Supply of Lids and Rings
WASHINGTON,
D.C.—The War Production Board (WPB) today made assurances to housewives of an
adequate supply of metal closures and rubber rings for the glass containers
essential to home canning. Additionally, the director of the WPB containers
division, Roswell C. Mower, announced the development of what he calls a “virtually
fool-proof” closure. The new closure consists of a glass lid, a rubber ring,
and a metal band with a screw mechanism that holds the lid in place. The new
closer is being manufactured in large quantities for the first time. However, to
ensure supply of conventional closures for glass jars, the WPB removed all quota
restrictions on the manufacture of metal lids. Use of zinc in the manufacture,
however, is still prohibited. This year marks an expansion of the canning
program.
