424 CORK INSULATION<br />

Covers for Junior Box.—As there is but a single opening <strong>on</strong> the<br />

Junior type Mechanicold, the full opening cover is supplied with dou-<br />

ble point hinges.<br />

These lids are made of 16-gauge nickel silver (weighing 2^/4 pounds<br />

to the square foot). The linings, also of nickel silver, are formed so as to<br />

fit inside the turned down edges of the top. This is known as telescoping<br />

and the joint is flooded with solder, making what amounts to <strong>on</strong>e piece<br />

c<strong>on</strong>structi<strong>on</strong>.<br />

Between the top and lining is <str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g> of pure <strong>cork</strong> board.<br />

The double point hinge permits of the full opening of the lid.<br />

The raised edge around the opening in the capping which received the<br />

lid, is die stamped and will not break down. It prevents moisture <strong>on</strong> the<br />

cover getting into the ice cream can.
