Device for cooling or heating liquids in a bottle

A device for cooling or heating a liquid contained in a bottle, said device comprising a tube having a tube wall and an open top end terminating said tube wall, said tube sized for insertion in the bottle and at least partially submerged in the liquid;

• a first container provided in said tube, a first container neck downwardly-extending from said first container and a first heat-exchanging fluid provided in said first container;
• a second container provided in said tube beneath said first container, a second container neck upwardly-extending from said first container and slidably receiving said first container neck and a second heat-exchanging fluid provided in said second container;
• at least one tube opening provided in said tube wall for flowing the liquid from the bottle or can, through said tube opening and said open top of said tube when the bottle or can is inverted;
• a seal provided in said second container neck to prevent commingling of said first heat-exchanging fluid and said second heat-exchanging fluid;
• and a button slidably disposed in said tube and contacting said second container for displacing said second container upwardly in said tube, contacting said seal with said first container neck, rupturing said seal against said first container neck and mixing said first heat-exchanging fluid with said second heat-exchanging fluid in said second container, responsive to application of pressure on said button.

A device for cooling or heating a liquid contained in a bottle or can having an internal bottle sleeve, said device comprising a first container provided in said bottle sleeve and a first heat-exchanging fluid provided in said first container;

• a second container provided in said bottle sleeve beneath said first container and a second heat-exchanging fluid provided in said second container;
• connecting means fixed to said first container and slidably engaging said second container;
• a seal provided in said second container between said first heat-exchanging fluid and said second heat-exchanging fluid to prevent commingling of said first heat-exchanging fluid and said second heat-exchanging fluid through said connecting means;
• and a button slidably disposed in said bottle sleeve and contacting said second container for displacing said second container in said sleeve contacting said seal with said connecting means, rupturing said seal and mixing said first heat-exchanging fluid with said second heat-exchanging fluid in said second container, responsive to application of pressure on said button.
