<p>PROBLEM TO BE SOLVED: To provide a glass bottle for the use in hot packing, which increases the cooling speed of liquid contents to keep it fresh so as to prevent the taste and quality of the contents from deteriorating. SOLUTION: A constriction is provided on the body of the bottle for the use in hot packing. The constriction enhances the convection of the liquid contents around the constricted part of the bottle, improving heat exchange between the lower and upper parts of the bottle. As a result, the temperature of the upper part of the bottle can be particularly quickly lowered so that the cooling speed of the contents is increased in total.</p> |
